下圖清晰地展示了一個完整的工作循環：

下面我們來詳細拆解這個過程及其應用。

工作原理詳解：四個步驟的循環

壓濾機的工作是一個周期性的過程，主要包括**頂壓、壓濾、松板和卸料**四個步驟。

1. 頂壓與合攏
– 液壓系統推動頭板向前移動，將一系列濾板緊緊擠壓在頭板和尾板之間。
– 每兩塊相鄰的濾板凹面相對，形成一個封閉的**濾室**，這是過濾發生的基本單元。

2. 壓濾與入料
– 給料泵將需要過濾的混合物料（如煤漿）從尾板的給料孔高壓打入各個濾室。
– 在壓力作用下，液體（濾液）穿過濾布，沿著濾板表面的溝槽流出機外。
– 固體顆粒則被濾布截留在濾室內，并逐漸堆積形成**濾餅**。當濾餅充滿濾室，濾液流量減少至成滴時，壓濾階段結束。

3. 松板
– 液壓系統換向，活塞桿帶動頭板退回原位，原本被壓緊的濾板隨之松開。

4. 卸料
– 傳動系統（如拉板裝置）工作，將濾板一塊塊拉開。
– 濾餅失去擠壓力的束縛，依靠自重從打開的濾室中脫落下來，完成卸料。卸料完成后，濾板被重新壓緊，進入下一個循環。

壓濾機的主要應用領域

憑借高效的固液分離能力，壓濾機在眾多行業中扮演著關鍵角色。以下是其主要的應用領域：

| 應用領域 | 具體用途舉例 |
環保與污水處理:市政污泥脫水、工業廢水（如電鍍、印染、皮革廢水）處理、河道淤泥處理。
礦物與冶金:選煤廠煤泥回收和洗水閉路循環、精礦過濾、尾礦干排。
化工與制藥:分離化工中間體、顏料、染料、催化劑、抗生素、維生素等。
食品與釀造:果汁、果膠、淀粉、食用油、砂糖、醬油、酒類等的澄清和提純。
其他工業:陶瓷原料脫水、高嶺土提煉、電石渣脫水等。

不同類型的壓濾機

根據結構和性能的不同，主要有以下幾種類型，它們各有側重：

廂式壓濾機：由一組凹進的濾板組成，濾室由相鄰兩塊濾板構成。它是目前應用最廣泛的類型，效率較高、濾板耐用。適用于精礦過濾、尾礦干排等。
板框壓濾機：由平板濾板和中空濾框交替組成，濾布固定在板框上。優點是更換濾布方便，但效率相對較低。
隔膜壓濾機：在廂式壓濾機的基礎上，部分濾板帶有可膨脹的隔膜。在完成第一次壓濾后，向隔膜內充入水或空氣進行二次壓榨，能進一步降低濾餅含水率。適用于對濾餅含水率有嚴格要求的場合。
立式壓濾機：采用垂直的濾板結構，通常自動化程度更高，結構緊湊，處理能力大，適用于對產品品質要求高的領域，如礦山冶金、食品醫藥等。

壓濾機的核心價值在于高效、可靠地將混合物料中的液體與固體分開。它通過一個看似簡單的循環過程，解決了從環境保護到工業生產中的眾多關鍵環節。如果你對特定類型的壓濾機或其在某個行業的應用有更深入的興趣，我很樂意提供進一步的信息。

2.Factors affecting the capacity of the filter press analysis of the filter press capacity is mainly determined by the filter press cycle efficiency, cake thickness, cake moisture content of three aspects. Circulation efficiency: the filter press is a batch operation equipment, to complete the unloading of a cake is to complete a cycle, the number of unloading of the cake can be completed per hour is the cycle efficiency. Production capacity=(weight of filter cake in a single cycle x cycle efficiency)–(weight of filter cake in a single cycle x recycling efficiency x water content). Through the table1The comparison shows that the filter press capacity can be increased by solving the problems of low circulation efficiency and thin cake thickness. In order to find out the reasons for the low capacity of the filter press, the factors that may lead to the substandard capacity of the filter press were analysed.

(1)Filter cloth quality poor filter press nonwoven quality requirements: air permeability2.5m 3 /m2-minFilter cloth weight750g/m2Rupture strength–radial direction320kN/mlatitudinal90kN/mThe surface of the filter cloth is smooth. Separately tested the1#, and2#Two batches of filter cloth, it can be seen that all indicators are met and are not the main factor affecting capacity.(2)Low compressed air pressure The Filter Press Operator's Manual requires that the press air pressure of the filter press be not less than0.8MPaThe pressure of the blowback air is not less than0.6MPaThe output pressure of the press air compressor and the backblow air compressor was confirmed to meet the production requirements of the filter press. Through the site to confirm that the output pressure of the press air compressor and the reverse air compressor both meet the production requirements of the filter press: the output pressure of the press air compressor is0.97MPaThe output pressure of the blowback compressor is0.75MPa, is not a major factor affecting capacity.

(3)Feed pressure setting low A filter press was selected at the site to test the relationship between the thickness change of the filter cake produced at different settings of feed pressure, from Fig.2Comparison of the table line graph can be seen, different feed pressure, the output of different thickness of the cake, feed pressure and cake thickness is positively proportional to the relationship between the main factors affecting the capacity.

(4)Low circulation efficiency "Filter Press Operation Manual" stipulates that: filter press circulation efficiency ≥2.5vice-/Hours. Randomly selected on site6One filter press test from feed–pancake unloading–The time required for the feeding process, from Table3It can be seen that the efficiency of the filter press cycle2.22vice-/hours, which falls short of design capacity and is a major factor affecting capacity.

(5)Feed solids low feed solids low, single sub-filter press to deal with the end of the bottom flow increased, but the amount of mud processing the same case increased the single sub-filter press operating time, need to reasonably control the feed solids, "Filter Press Operator's Manual" stipulates that: Filter press feed solids must be controlled at>500g/LAccording to the survey, it was found that2020surname Nian7Month-12The average feed solids of the filter presses for the month was only 0.5 per cent.452g/L, which is not up to scratch, is the main factor affecting capacity.

(6)The effect of flocculant addition after the increase in the amount of red mud, red mud in the settling tank residence time becomes shorter, the ability of red mud free settlement, compression decreases, the system needs to be added in excess of the flocculant, in order to ensure that the red mud settling, compression performance, excessive flocculant resulting in the viscosity of the red mud increased, the unloading of the cake of the filter press decreased, affecting the operating efficiency, is the main factor affecting the production capacity.

3.Measures to increase the capacity of filter presses

(1)Determine the most reasonable feed pressure to find out the relationship between feed pressure and cake thickness, cake moisture content, determine the optimal feed pressure for industrial testing, to find out the relationship between cake thickness and cake moisture content under different feed pressures to ultimately determine the most reasonable set pressure. In0.3~0.6MPaThe cake thickness and moisture content are tested at different feed pressures (each pressure is tested at a different level).3(take the average value), through the test to find out the relationship between the feed pressure and the thickness of the filter cake, water content, in order to ensure that the water content of the filter cake ≤25%conditions to achieve the thickest filter cake thickness. From the table4It can be seen that: as the set pressure is increased, the thickness of the filter cake gradually becomes thicker, but the pressure mentioned0.52barAfter that, the thickness of the filter cake is not obvious; with the set pressure to increase the water content of the filter cake shows a rising trend, but the amplitude is small, the pressure reaches0.57barAfter that, the water content of the filter cake exceeds25.0%; All things considered, the pressure is set at0.52~0.56barBetween both the water content of the cake and the ideal thickness of the cake can be obtained.

(2)Improve filter press cycle efficiency Filter presses use aPLCControl, according to the manufacturer to provide the filter press related information, the filter press operating procedures for each step of the time required for the analysis of the demonstration, to improve the efficiency of the filter press cycle, it is necessary to shorten the time of some steps, through the actual test, and ultimately determine the time to adjust the time of the steps can be feed delay, press time, blowing the filter cake, and the development of the implementation of the adjustment of the programme. The purpose of the feed delay is to ensure that the filter chamber is full of slurry to form a thick cake, if you shorten the feed delay, the thickness of the cake is not affected, you can shorten the time, through the test, the filter press feed delay is set in the240~160sBetween, the change in cake thickness is small and negligible, but decreases to160sThe large drop in cake thickness later on is evidence of the feed delay160sThis ensures that the filter press chamber is filled with slurry and a good cake thickness is obtained.160sThe later time is useless and can be removed. The length of the pressing time determines the water content of the filter cake, so the water content of the filter cake is tested on site under different pressing times, and the extra time is eliminated to choose the best pressing time. Through on-site observation, it is found that a large amount of water is discharged from the filtrate pipe at the beginning of pressing.120sThe amount of water gradually decreases thereafter.160sAfterwards almost no water is pressed out, based on this phenomenon, the selection of the160~240sTime period, per10sMeasurement of cake moisture content, per time point3The average value was taken. The test data show that the press180sAfter that, the water content of the filter cake was basically unchanged and the pressing time was set at180sThe water content of filter cake can meet the requirement of water content of filter cake. Blowing back the filter cake, the length of the blowing time determines whether the water content can be further reduced after the filter cake has been pressed, and the changes in the water content of the filter cake under different blowing times are tested on site, so as to eliminate the extra time and select the best blowing time. According to the implementation experience of shortening the pressing time and on-site observation, it is also found that more water is blown out in the early stage of blowback, and almost none in the later stage, according to this law, the best blowback time is selected.10~100sTime period, per10sMeasurement of cake moisture content, per time point3times and take the average value. The test results prove that the blowback60sAfter that, the water content of the filter cake was basically unchanged, and the time of the backblowing air was set at60sIt will be able to meet the water content requirement of the filter cake. According to the filter press programme time adjustment scheme, the operating programme and time of the filter press are optimised: the filter press feed delay time is adjusted according to160sSetting, press time by180sSetting, backblowing time is set by60sSettings. Test after adjustment10The time per cycle for each filter press was used to calculate the cycle efficiency from Table5It can be seen that10All filter presses have a cycle efficiency of2.5vice-/Hours.

(3)Improve the feed solids in principle, the higher the feed solids control of the filter press, the better, which will reduce the amount of attached liquid, reduce the feeding time, the filter press operating time will be reduced, the filter press capacity will be increased, the power consumption will also be less. But the feed solid content is too high will make the red mud is very easy to stain on the filter cloth, resulting in filter cloth cake unloading effect will be worse, the filter cloth filtration effect will be worse, the water content of the cake has increased, the filter cloth is easy to clip between the mud and lead to the filter plate splintering material, increase the failure rate of the filter press. Through continuous exploration, it is found that the feed solid content of filter press is controlled in500~550g/LBetween them, the filter press operates with high efficiency, low failure rate, and good effect of cake unloading from the filter cloth. In order to preserve the stability of the feed solids of the filter press, it is necessary to grasp the operation of the washing and settling tank: firstly, the bottom-flow pumps are backed up and overhauled in accordance with the cycle to ensure the stable operation of the equipment; secondly, the solid content of the discharged material is controlled stably through the on-line instrument and density meter, and the solid content of the discharged material is controlled in accordance with the cycle.500~550g/LEnsure that the outlet pressure of the outgoing diaphragm pump is greater than9MPa.

(4)Precise control of flocculant additive alumina production need to use flocculant to accelerate the settlement, flocculant additive, will increase the content of polymer organics in the system, in order to strengthen the production efficiency of alumina, in the red mud washing work to add flocculant beyond a certain range, plate and frame filter press filter cloth unloading the cake will gradually reduce the effect of this time the red mud cake will be in the filter cloth, so it is not difficult to see that the flocculant for the filter cloth has a certain impact on the role of flocculant, will lead to the increase in the moisture of the cake itself. Certain impact on the filter cloth will lead to an increase in the moisture of the cake itself, so in the application of flocculant need to control the amount of flocculant, flocculant dosage control also need to ensure the flexibility of the need to control, combined with the model of the filter cloth and the use of experience in selecting the dosage of flocculant, will be controlled in the range of standard ratios, to ensure the effective operation of the eventual improvement of the production capacity of alumina.

4.Conclusions By adjusting the feed pressure setting of the filter press to 0 . 5 2 ~0.56MPaThe filter press feed delay is set to160sThe press time is adjusted to180sThe blowback time is adjusted to60s; Increase feed solids control to500~550g/Lbetween; precise control of the addition of settling flocculants and other improvements.2021surname Nian1-3The capacity of the filter presses was increased to56.7t/hThe number of people who have been in the market since the beginning of the year is higher than the previous one.12.6%The filter presses are operating at a rate of73%(math.) genus2020The annual filter press operating rates were all85%In addition, the reduction in the operating rate of the filter presses has resulted in spare capacity and fewer filter presses than would otherwise have been required to meet production requirements.1The number of filter presses has been reduced, and the number of operating equipment has been reduced, saving on spare parts and material consumption, reducing energy consumption, and achieving the following results38$10,000,000/year's economic benefits.

Diaphragm type plate and frame filter pressIt is the commonly used equipment in tailing coal treatment and dewatering in coal processing plant, which is widely used due to its advantages of strong processing capacity, good dewatering effect, low noise, low energy consumption and so on. Guandi Coal Processing Plant, as the supporting pit-head coal processing plant of Guandi Mine, most of the coal transported during the production process of raw coal mining is mixed with mud and sand rocks, and these impurities and coal are mixed to form coal sludge, so it is necessary to use special filtration equipment for filtration and processing work. Plate and frame filter press as a commonly used filtration equipment in coal mines, its performance directly affects the economic benefits of coal mines, based on this, to strengthen the plate and frame filter press equipment to improve the processing, enhance the efficiency of the plate and frame filter press is extremely important. This paper will optimise the performance of the filter press from the perspective of improving the design of the plate and frame filter press pulling device, to provide reference for the optimisation and upgrading of the coal mine filter press.

1 Overview of Guandi Coal Processing PlantGuandi Coal Processing Plant is a pit-type coal processing plant supporting the construction of Guandi Mine of Xishan Coal and Electricity Group, with a design capacity of 400×104t/aThe raw coal to be washed comes from the Guandi Mine and is a high quality fat coal. The use of desliming non-pressure feeding three products heavy media+Screw sorting machine+Combined flotation process flow. The dewatering of the flotation concentrate at this plant is performed by two ZKG450/2000-U The quick release diaphragm filter press is complete.

2 Plate and frame filter pressThe overall design of the plate and frame filter press is the use of pressure pumps, the slurry will be pumped into the two adjacent filter plate formed in the closed space, the formation of a pressure difference between the two sides of the filter cloth, so as to achieve the effect of solid-liquid separation. Plate and frame filter press consists of material transport system, filtration system and line system. The material transport system consists of four parts: motor, base, coupling and hydraulic pump; the filtration system consists of plate pulling device, fixed filter plate, filter plate and frame, beam, support and accessories, plate pulling assembly, filter cloth and filter paper, etc.; the line system mainly consists of two parts: the disc assembly and the steel pipe.[1]. Figures. 1 because of ZKG450/2000-U Schematic diagram of a type plate and frame filter press.

3 Plate and frame filter press pulling device composition and working principle of the pulling device as a whole is through the thrust plate, compression device, base and hydraulic cylinders and various components.The working principle of the pull plate device is driven by the piston in the hydraulic pump in the cylinder to drive the pull plate device for tensioning activities, through this tensioning activities to squeeze the thrust plate, the thrust plate to remain fixed in order to play the effect of extruding the mud, to achieve the effective extrusion of the filter cloth. This process will produce a large extrusion pressure, reasonable selection of component materials will enhance the overall performance of the strength of the pull plate device. Usually in the plate and frame filter press above the design of the steel plate for the crushing of mud, falling into the plate and frame filter press after the crushing of mud through the steel grille will be due to the impact of the crushing into small pieces of cake, small pieces of cake will be conducive to the subsequent transfer and storage, the size of this grille can be flexibly adjusted according to the body of the size of the mud cake. Slope treatment is carried out at the discharge opening, and the treated material will have a 3/1000 The downward slope of the conveyor belt also ensures that the water on the conveyor belt can flow along this slope without accumulating on the conveyor belt. The filtration process starts at the inlet, where the mud enters the inlet and is uniformly transported through the filter chambers, where it is centrifuged by a centrifugal pump for solid-liquid separation, and where the solids are compressed and retained in the filter chambers in the form of a sludge cake. After air-drying process in the air-drying interface, the moisture content of the solid part will be greatly reduced and transferred to the next outlet.

4 Optimisation of plate and frame filter press pulling devices

4.1 The selection of the material of the pulling plate material on the pulling plate machine frame selection can significantly improve the strength of the pulling plate device and the overall structural performance, in the improvement of the design of the frame beams will be selected Q345 Model materials for welding, and the key parts of the structure to strengthen the processing, to ensure that the entire frame has a high structural strength, to ensure that the pulling device for pulling the plate operation will not occur when the beam deformation and torsion of the problem. At the same time, the material of plate frame including thrust plate, compression plate and other plate types are also selected.Q345 Model material to be welded to the hydraulic pump cylinder blockSilicon-manganese material treatment ensures the working strength of the pulling plate device. Reasonable material selection for the pulling device can greatly enhance the service life of the components of the pulling device and reduce the maintenance cost of the plate and frame filter press equipment. At the same time, it avoids the influence on the working efficiency of the plate and frame filter press caused by the failure of the pulling plate device, and improves the working efficiency of the plate and frame filter press..

4.2 Plate and frame filter press in the installation error adjustment plate and frame filter press in the installation process due to the installation of normality will cause large errors, in the installation process, the horizontal error of the beam usually presents a 1.5mm/m The horizontal levelling error in the transverse direction as well as the longitudinal levelling error. The smaller this error is, the smoother the beam is and the less resistance the pulling device has in the working process. If the beam is placed completely horizontally, the pulling device will only be subject to horizontal friction during the working process; while the error exists and the larger the error value is, the plate frame will have a vertical force, and the friction between the plate and the plate will increase the squeezing pressure, which will play a hindering role in the work of the pulling device and accelerate the wear and tear of the components. Therefore, in the installation process of the filter press, it is necessary to carry out levelling operations on the foundation first. You can use the level meter and other geological surveys, grouting and grouting of the foundation, embedded steel processing, to enhance the bearing capacity of the foundation as well as the flatness of the foundation. After processing the foundation, the equipment is installed in accordance with the equipment installation specifications, the specific programme is shown in the figure. 4. Use the mobile crane to lift the lugs of the plate and frame filter press, and pull the whole machine to the pre-levelled foundation position. After installing in place, use the level to adjust and check the flatness of the plate and frame filter press again, and adjust it to within the specified error for the fixing of the plate and frame filter press. Install the base bolt to fix the plate and frame filter press, and keep the legs freely adjustable. Completion of the above operations will complete the installation of the plate and frame filter press and improve the working efficiency of the pulling device..

4.3 Automation of the pulling plate design of the current plate and frame filter press pulling device is not high degree of automation, the equipment often occurs during the operation of the oil failure and spring damage, equipment maintenance and parts replacement will significantly reduce the efficiency of the plate and frame filter press. Based on this phenomenon, we must carry out the automation design of the plate and frame filter press, and design the oil electronic control system and the adaptive adjustment of the pulling device. So that the pull plate device in the operation process according to the pressure required by the filter cloth to flexibly adjust the size of the pressure, to avoid excessive pressure output caused by the damage to the pull plate device and the plastic deformation of the spring. Through the adaptive adjustment of pressure can reduce the pressure output of the oil system, change the traditional plate and frame filter press in the process of mud processing, the spring of the pulling device of the height of the operation of the damage, to improve the short service life of the components of the plate and frame filter press.[4].. By designing variable frequency geared motors, sprockets, drives and PLCController and other components for the automatic control of the pulling device, composed of pulling plate drive system. The filter plates of the plate and frame filter press are divided equally, and each plate is fixed with a chain and connected by a PLC The controller is controlled to realise the high-speed operation of the pulling plate, and the speed is automatically reduced and automatically converted when the plate is taken away. In the process of pulling the plate, it realises the effect of pulling one group at a time and pulling all the filter plates in sequence, discharging the material and loosening the pressure plate after the filtration work is completed. With the above operation, the pulling device can be realised. PLC The controller control system improves the automatic operation level of the plate and frame filter press and reduces the damage to the equipment caused by improper manual operation. Adaptive adjustment of the pulling plate device is realised, and the pressure output is reasonable according to the composition of the filtrate, which reduces the damage to the pulling plate device. This operation can greatly improve the service life of the components of the pulling plate device, reduce the replacement cycle of the components, and save the maintenance cost of the plate and frame filter press equipment in coal mines..

5 Analysis of the application effect of the improved pulling plate device was carried out in the field test after completing the improvement of the pulling plate device. Through the inspection and installation of the plate and frame filter press after the practicality of the test, the test process found that the plate and frame filter press pulling device in good operating condition. The material selection of the pulling device is good and there is no damage to the parts, and the analysis and testing of the composition of the filtrate also meets the relevant specifications. Comparing with the working effect of the original plate and frame filter press, it is found that the efficiency of the plate and frame filter press has been increased by almost 20% after the horizontal installation and adjustment. 20%The failure rate of the filter plate and the puller device is greatly reduced, and the replacement cycle of the puller spring and plate components is delayed. 1 times around.

This improvement saves the coal mining company nearly $100,000 on just one plate and frame filter press. 20 The cost expenditure of 10,000 yuan, the effect is very significant. Can be carried out to improve the plate and frame filter press pulling plate device large-scale popularisation and application.6 Conclusion The Guandi Coal Processing Plant has been developed through the ZKG450/2000-U With the optimisation of plate and frame filter press pulling device, the working efficiency of plate and frame filter press has been greatly improved, and the damage rate of equipment parts has been greatly reduced. The improved plate and frame filter press has good practical effect and feasibility, which brings great economic benefits to the coal mine, and also provides a successful case demonstration for the innovation and upgrading of coal mine equipment.

1 Compound chemical process for treating river and lake sludge The compound chemical process scheme integrating dredging of sludge, separation of rubbish, sand and gravel, conditioning and coagulation, first flocculation, first concentration, secondary flocculation, secondary concentration, tertiary flocculation, belt filter press dewatering and resource utilisation, etc., is shown in Fig. 1, with pumping of river and lake sludge, and the specific treatment process routes in the dotted box.

2 Process operation for treating river and lake silt The silt after waste sorting and sand and gravel separation has a small particle size, and because of the large amount of humus and other pollutants, it forms a gelatinous structure that is difficult to dewater under natural conditions. The main function of adding conditioning agent is to break the gel, stabilise the ionic pollutants (e.g. heavy metal ions, etc.), deodorise, coagulate, etc., and form tiny particles. After conditioning, the sludge is coagulated into easy-to-sediment flocs by flocculant net trapping, and the sludge and water are initially separated through a concentration process (by means of a buffer tower). The buffer tower homogenises and buffers the slurry and removes most of the water in the slurry to increase the solid content, so as to provide a guarantee for the continuous work of the subsequent equipment. It has been proved that the more suitable water content after the first concentration is controlled at 85-90%, too low a water content will cause difficulties in releasing the underflow and clogging of the pipeline; too high a water content will increase the hydraulic load of the subsequent equipment and lead to the decline in operating efficiency. The sludge after primary concentration is flocculated for the second time, and then it is thickened for the second time, adopting the belt thickening method, and the water content is reduced to 70-80%. When the sludge after secondary concentration is flocculated for the third time, the flocculant is different from that of the previous two times, and the flocculating agent is different from that of the previous two times.It is like breaking up the flocs first and then flocculation again, releasing a large amount of free water wrapped up in the concentrated flocs to meet the requirements of high intensity operation of dewatering immediately after the filter press and realise high effective dewatering efficiency. The sludge is pressed by the high-pressure belt dewatering machine into solids with a water content of ≤50%.

3 Compound chemical process application system operation effect According to the current domestic winch suction dredging volume, 8 inch winch suction dredging volume per hour for the underwater side of 60 ~ 100 m3, a single set of units per hour to deal with the absolute dry sludge volume of 15 ~ 30 t per hour can be dewatered sludge volume of 20 ~ 40 m3. The composite chemical process is applied in the dredging and curing project of Meishe River in Haikou City, Hainan Province, and the width of the equipment is controlled to be within 3 m. The pumping capacity of a single set of system is 15 to 30 t per hour. A single set of system hourly pumped into the slurry volume of 200-500 m (rated value of 3,350 m3), after the rubbish sand and gravel sorting, the slurry water content ≥ 95%, through the conditioning and flocculation into the thickener tower, the first concentration of the hourly discharge of 150 m3 of sludge, the range of water content in the 85-90%, the hourly discharge of clear water volume of 100-300 m3. After the second flocculation, the sludge enters the belt thickener, and after the second flocculation, the sludge is discharged 50-80 m3 per hour, and the water content is in the range of 70-80%. The sludge enters the high-pressure filter belt dewatering machine after the last flocculation, and after the dewatering, the sludge cake discharged is about 20-40 m3 per hour, and the water content can be reduced to the lowest value. Table 1 shows the results of the two experiments with a total of 350 m3 of slurry pumped per hour. The water content of the sludge becomes lower after each concentration dewatering process, and the final cake formed by filter press dewatering has a water content of less than 50%, which is in line with the requirements of sludge treatment for reduction and resourcing, and shows that the chemical process is feasible.

First, filter press pump feeding slow cause analysis

1. Conveying pipeline blockage: If the conveying pipeline is blocked when the filter press pump is conveying materials, it will lead to poor material flow and slow down the feeding speed. Possible reasons include the inner wall of the pipeline is not smooth, the bending radius of the pipeline is too small, and the material contains impurities.

2. Pump speed is too low: The speed of the pump is an important factor affecting the feeding speed. If the pump speed is too low, it will result in a reduction in the pump output flow rate, thus affecting the feeding speed. Possible causes include motor failure, loose or worn drive belts, and mechanical failure of the pump.

3. Insufficient suction of the pump: the filter press pump needs to have a certain suction to absorb the material in the process of conveying the material. If the suction of the pump is not enough, it will lead to sucking up the material at a slower speed, thus affecting the feeding speed. Possible reasons include low pressure at the suction port of the pump and cavitation.

4. Influence of material characteristics: different materials have different characteristics such as fluidity, particle size distribution, water content, etc., and these factors will affect the feeding speed of the filter press pump. For poor fluidity, large particle size, high water content of the material, the feeding speed may become slower.

5. Improper operation: In the process of using the filter press pump, if it is not operated properly, such as frequent starts and stops, overloaded operation, etc., it may lead to the pump's loading speed to become slower.

Second, to solve the filter press pump feeding slow method

In response to the above possible causes, here are some ways to solve the slow feeding of the filter press pump:

1. Cleaning or replacing pipes: For slow loading problems caused by clogged pipes, measures such as clearing the clog, replacing the pipes or increasing the bending radius of the pipes can be taken to restore smoothness to the pipes.

2. Check and adjust the speed of the pump: check whether the pump motor and transmission device work properly, adjust the speed of the pump to the normal range to ensure that the output flow of the pump meets the requirements.

3. Improve the suction of the pump: check whether the suction port pressure of the pump is normal, if necessary, you can adjust the working parameters of the pump or take other measures to improve the suction port pressure. Pay attention to prevent the occurrence of cavitation.

4. Improvement of material characteristics: For materials with poor fluidity, large particle size and high water content, measures such as adding flow improvers, crushing large-size materials and reducing water content can be taken to improve the fluidity of the materials, thus speeding up the feeding speed.

5. Standardised operation: In the process of using the filter press pump, irregular operations such as frequent starting and stopping and overloading should be avoided. Operate in accordance with the specified operating procedures to ensure the normal operation of the pump and the feeding speed.

6. Regular maintenance: Regular maintenance of the filter press pump, cleaning pipes and pump body, replacing worn parts, checking seals, etc., in order to keep the pump in good working condition and prolong its service life.

7. Seek professional help: If none of the above methods solves the problem, it is recommended to seek professional help in order to better diagnose the problem and fix it.

Through the above analysis, we can conclude that the reasons for the slow feeding of the filter press pump mainly include the clogging of the conveying pipeline, the low speed of the pump, insufficient suction, the influence of material characteristics and improper operation. In order to solve this problem, we need to start from many aspects, including cleaning or replacing the pipeline, checking and adjusting the speed of the pump, improving suction, improving material properties and standardising operation. In order to ensure the efficient and stable operation of the filter press pump, we should also pay attention to the regular maintenance of the equipment. In the event of equipment failure, we should seek professional help in a timely manner to repair, so as not to bring unnecessary losses to the production of equipment downtime for a long time. In the actual use of the process, we should also pay attention to the operating conditions of the equipment and performance changes, in order to find and solve potential problems in a timely manner. Strengthen the daily inspection and maintenance of equipment is also an important measure to ensure the normal operation of equipment. Through regular inspection and maintenance of the key parts of the equipment and wearing parts, you can find and deal with potential problems in a timely manner, to avoid the occurrence of serious equipment failure or downtime. Strengthening the daily maintenance of equipment can also extend the service life of equipment and reduce maintenance costs. Therefore, operators and maintenance personnel should fully understand the importance of routine maintenance, and take effective measures to ensure the normal operation of the equipment and the use of results.
