what is Jack Filter Press? The Jack Filter Press is an intermittent filter press machine for the solid-liquid separation of various suspensions. The separation effect is good and easy to use. Widely used in petroleum, chemical industry, dyestuff, metallurgy, pharmacy, food, paper making, sewage treatment and other fields where solid-liquid separation is required. Suitable for small-scale filtration industry. The Press Filter is mainly composed of three parts: the frame part, the filter part and the compression device. When the Filter Presses is working, the hand wheel is rotated, and the pressure plate is pushed by the small gear halo and large gear driving the screw, which presses the filter plate and filter medium (filter cloth) between the pressure plate and the stop push plate to ensure that the filter material (slurry) is pressurized and filtered in the filter chamber under working pressure. (1) Frame part: The frame forms the foundation of the Filter Presse and is used to support the filtering mechanism and connect other parts. It mainly consists of the push plate, pressure plate, press plate and main beam. (2) Filtration part:It consists of the Filtration Plate and the filter media (filter cloth) sandwiched between the filter plate, arranged in a certain order on the main beam to form the filter unit (filter chamber).

How is the filter press cared for and maintained?
2023 / 04 / 10
How is the filter press cared for and maintained? The filter press is a common type of solid-liquid separation equipment that requires strict adherence to the operating system. Once the Press Filter is operated incorrectly, it is prone to various faults, which seriously affect the use effect and filtration effect of the filter press equipment. Therefore, it is very important to do a good job in the daily maintenance and upkeep of the plate and frame Filter Presses. Maintenance and servicing of the Filter Press Machine: (1) Check carefully whether the connections are firm and whether the parts are well used, and if abnormalities are found, the maintenance personnel must be notified in time for maintenance. If it is not used for a long time, the filter cloth and Filtration Plate should be cleaned first and then dried in the sun. The power supply must be cut off when dismantling the module. Check the bearings and piston rod parts so that the parts are kept clean and well lubricated to ensure the flexibility of the moving parts. (5) Conduct insulation and reliability tests on the electrical control system. If abnormalities are found, the electrical components should be repaired or replaced in time. Before pressing, check the filter cloth carefully to ensure that it is not folded or damaged, and make it flat and intact to ensure the filtering effect. Maintenance and servicing of the hydraulic station: Every refuelling needs to be done vi
How are the process steps of the filter press manufacturer divided?
2023 / 04 / 07
The process of a plate and frame filter manufacturer is divided into several machining stages and cannot simply be judged by the nature of a surface finish or a process. For example, the positioning datum of the workpiece needs to be very accurate in the semi-finishing stage or even in the roughing stage, and it is common to arrange some roughing processes such as drilling in the finishing stage. Process division The process concentration of the plate and frame filter manufacturer is that the processing of the parts is concentrated in a few processes, but each process has more processing content; on the contrary, there are a large number of processes in the whole process, and each process has relatively little processing content. (1) The characteristics of process concentration in filter presses. ①It is conducive to the use of multi-tool and multi-edge, multi-axis machine tools, CNC machine tools, machining centres and other special equipment and process equipment with high productivity, thus greatly improving productivity. ②Reduces the number of processes and shortens the process route, thus simplifying production planning and production organization. ③Reduced the number of equipment and correspondingly reduced the number of operators and production area. ④Reduces the number of times the workpiece is mounted, which not only shortens the auxiliary time, but also allows more surfaces to be machined under one mounting, and it is easy to ensure the r
Professional details on the structure and principle of filter press products
2023 / 04 / 06
Professional details on the structure and principle of filter press products In the early 18th century, filter press equipment began to be used in chemical production. Today, it has become an indispensable facility for many production areas. Driven by this market environment, Shenzhen Hongfa Filter Press Equipment Factory was established in 2008 and has developed into a well-known manufacturer of filter press equipment in China, with three branches in China. Shenzhen Hongfa Filter Press Equipment Factory produces Filter Press Machine with simple structure, good separation effect, easy to use and wide range of application. At present, the products produced by Shenzhen Hongfa Filter Press Equipment Factory have been widely used in environmental protection, chemical industry, mining and other fields. The Filter Presses equipment mainly consists of frame, Filtration Plate, compression system, hydraulic station and electrical control cabinet. The frame is the basic part of the Flter Press equipment, including the seat, compression plate, thrust plate and main beam, which mainly supports the compression device and the filter plate. The thrust plate is connected to the stand and places one end of the Filter Presse on the foundation. The compression plate is mainly used to press the filter plate filter frame and rollers on both sides support the plate rolling on the beam track. The filter plate is mounted on the main beam between the press plate and the thrust plate, clamping the filter cloth. The beam is the main load-bearing part of the filter press. Depending on the anti-corrosion requirements of the operating environment, rigid PVC, PP polypropylene, stainless steel coating or new anti-corrosion coatings can be selected. In the working process of the filter equipment, the compression device pushes t
A brief introduction to the main classifications of filter press equipment
2023 / 04 / 03
A brief introduction to the main classifications of filter press equipment Solid-liquid separation is a mechanical method of separating discrete solid particles from liquids and is widely used in industrial production. The Filter Press Equipment is an important facility to complete the solid-liquid separation. Shenhongfa said that with the continuous development of modern industrial production, Press Filter equipment has become a necessary equipment for food, pharmaceutical, mining, environmental protection and other industries. The Filter Press Machine is divided into plate and frame type Filter Presses and chamber type filter press. It is a kind of intermittent pressure filtration equipment, used for solid-liquid separation of various suspensions. During operation, the Flter Press equipment relies on a compression device to compress the Filtration Plate, which then pumps the suspended liquid material into the filter chamber, separating the solid particles from the liquid material through the filter cloth. The Filter Presses equipment is made up of the frame, the filter plate, the compression system and the electrical control cabinet. Depending on the compression system, the Flter Press can be divided into jack type, mechanical compression type and hydraulic compression type. In addition, according to the different outlet methods of the Filter Presse, it can be divided into open-flow and dark-flow. Open flow is the outlet method where the filtrate is discharged directly from the outlet hole of each filter plate; dark flow is where the filtrate of each filter plate is mixed and discharged from the outlet hole. Of these, the open flow is more commonly used. In addition, for customers with special needs, it is also possible to cu
How to overhaul a filter press after it has stopped working?
2023 / 03 / 31
How to overhaul a filter press after it has stopped working? Every holiday season, Filter Press Equipment in many industries should be out of action. To keep filter presses in better working condition for the future, Filter Press should be serviced and maintained during the holidays to ensure safe and proper operation. How do I repair a Press Filter? What are the steps? Replace the hydraulic oil: 1.Replace the hydraulic oil: It is recommended to replace all the hydraulic oil in the Filter Press Machine again and clean the oil tank. Due to long-term work, the hydraulic oil will deposit impurities in the inner wall of the hydraulic system in the mailbox due to wear and tear. Therefore, for the next normal use, we need to replace all the hydraulic oil. 2. Filtration Plate handle overhaul: Due to the long working hours of the Filter Presse, the filter plate handle is operated a lot and it is easy to cause wear and error. Therefore, we need to take out the filter plates one by one from the Press Filters and check the filter plate handles carefully. Once abnormalities are found, they need to be repaired immediately. Once the handle is found to be badly worn, it is recommended to replace it with a new one. 3.Filtration Plate: During the work of the Press Filters, the filter plate often moves back and forth repeatedly and is also subject to great pressure, which can easily lead to broken filter plates or incorrect filter plate handles. Therefore, it is recommended to stop the work of the filter press and check whether the filter plate is cleaned and whether there are cracks
The main advantages of the filter press
2023 / 03 / 30
The main advantages of the filter press The main advantages of the Press Filter include high efficiency, good filtration, relative durability of the Filtration Plate (under the same conditions) and a high degree of automation. In addition, it is equipped with a filter cloth device that can be cleaned automatically, which usually does not require frequent replacement of the filter cloth. Filter Press Machine feed pressure; in the actual production process, the filtration pressure is generally provided by the feed pump (the proportion of combined feed from the on-site pump and air compressor is very small and will not be discussed here). Therefore, an extremely important factor affecting the filtration speed is the feed pressure of the feed pump. The feed pressure directly affects the working conditions of the Filter Presses, and the separation effect of the filter press is also very much related to the Flter Press. In actual use, it is found that in the process of Filter Presse dewatering, most of the water can be discharged by reducing the porosity of the filter cake through hydrostatic pressure, but the dewatering effect is not ideal and can only be achieved by increasing the hydrostatic pressure. The possible reason for this is that as the pressure increases, the porosity of the filter cake gradually decreases and the pore saturation of the filter cake gradually decreases. However, when the saturation of the filter cake is close to the residual saturation, the moisture of the filter cake basically does not decrease. Analysis of the microstructure of the filter cake shows that at this point the particles form an arch bridge structure and the moisture contain

The Plate And Frame Press for slurry treatment enable slurry treatment trucks to reach a water content of around 60%. The slurry treatment truck is a model for on-site sewage treatment and is equivalent to a small mobile sewage treatment plant. It eliminates the need for a long construction cycle, large investment and large area for sewage treatment plants, without the cumbersome process of project planning and land acquisition. Conventional suction and purification vehicles generally use a folding Screw Filter Press to treat mud, and can extrude mud cakes with a water content of about 80%. The slurry treatment truck can handle all flocculable sewage and sludge, but the Filter Press Machine is large and the plate and frame filter press is not as fast as the folding screw machine, so it is mainly used to treat slurry and other sewage and slurry that cannot be treated by the folding screw machine. 1.More than 80% of the slurry treatment carts are made of stainless steel, and more than 98% of the box pipes in contact with the water are made of stainless steel, which has a longer service life and is more convenient to clean. 2.The mud treatment vehicle has good treatment effect, the treated sewage can reach the national emission standard, the mud cake can reach the sludge landfill standard, it can well treat various types of sludge. 3.The mud treatment truck can also choose diesel generator when operating with external three-phase power supply, and can generate its own p

The differences between plate and frame filter press and Belt Filter Press can be summarized as follows. There are many varieties of plate and frame filter presses and belt filter presses. Let's talk about their similarities. Plate and frame filter presses and belt filter presses are widely used in municipal wastewater treatment and food processing. Plate and frame filter presses and belt filter presses are widely used in petrochemical, metallurgical manufacturing, mining, metal forging, pharmaceutical, electronics, chemical and other fields. Both types of equipment are capable of completing the filtration and separation process of solid-liquid mixtures. We are responsible for receiving and managing the materials involved, treating the wastewater, and maintaining the condition of the facility. What is the difference between plate and frame filter presses and belt filter presses? Plate and frame filter press. This equipment has a simple structure and is highly functional. Compared with the belt filter press equipment, there are the following differences. 1) The task of plate and frame filter press is operated intermittently, i.e. the operation forgets a completed task round and starts a new task from the beginning, i.e.: feeding - filtering - pressing, boring - discharging. As a result, some equipment requires more than one person to operate together, which increases the probability of equipment damage. 2) An additional process of replacing the filter cloth. The process of replacing the filter cloth in a box-type filter press is more complicated. The nature of the filter cloth directly affects its resorption performance and thus the efficiency of the filter press. 3) The water content of the filter residu
The history of filter press development and cleaning methods after use
2023 / 03 / 11
The history of filter press development and cleaning methods after use This type of filter pressees was first used in the chemical industry in the 18th century and is still widely used today in the chemical, pharmaceutical, metallurgical, dye, food, brewing, ceramic and environmental industries. The pressure filter press machine consists of multiple filter plate that are stacked to form a filter room and includes a filter frame that uses pressure as the driving force. Filter presses are intermittent in operation and are divided into three different types, including plate and frame filter press, chamber filter press and vertical filter press. Filter plates offer stable performance, easy operation, and safety and labor saving. Filter plates made of metal and plastic are made by casting or molding and have the characteristics of resistance to high temperature, high pressure and long-lasting durability. How do we usually clean the filter press after using it? Let's learn more about it: When performing filter cake cleaning, sometimes it is necessary to perform clear flow one-way/bidirectional washing, or dark flow one-way/bidirectional washing. Clear flow one-way washing means that the washing liquid enters from the washing liquid inlet holes on the thrust plate in sequence, passes through the filter cloth, the filter cake, and then flows out from the non-porous filter plate. During this process, the liquid flows out of the nozzles on the orifice plate and closes. The exit nozzles without holes are open.

As a device for solid-liquid separation, the filter press has some essential components, that is, the frame, filter plate and filter cloth. Whether it is a jack filter press, a hydraulic compression filter press, a mechanical compression filter press or a hydraulic compression filter press, or a filter press of any form and material such as a box type or a plate frame, these three items are indispensable. . So do you know what role does the filter press play in sludge dewatering? What is it about the material selection? Shenhongfa Company briefly analyzes the little knowledge about the filter plate of the filter press. The filter plate of the filter press is designed with some concave and convex dots, which play a vital role in the filtration and dehydration capacity of the filter press. It can speed up the flow rate of the equipment and shorten the filtration cycle, thus greatly improving the working efficiency of the filter press. During the operation of the filter press, the filtrate will not be limited by the direction, and will flow around along the line formed by the bumps, and it is the existence of the bumps that reduces the flow time of the filtrate and greatly improves the filtration speed. The bumps on the filter plate further expand the filter area to help the filter performance of the filter press to be in a stable state, which not only protects the filter cloth from damage, but also prolongs the service life of the filter press. When selecting a filter plate, the user must first determine the size of the filter plate of the existing filter press, and then deter
When to change the press cloth? Shen Hongfa is here to tell you.

The filter plate and filter cloth of the filter press are important components to ensure the normal solid-liquid separation of the filter press, and the filter cloth is also a vulnerable part. So, how long can a piece of filter cloth, or a set of filter cloth, last? In fact, there is no strict specific time for the service life of the filter cloth of the filter press, and more judgments come from the accumulation of experience. Generally speaking, as long as the filter cloth is not damaged, the ideal effect of the filter can be achieved by extending the mud feeding time appropriately, so there is no need to replace the filter cloth; if the mud pressing in a factory is very tight, it must maintain a relatively high mud pressing efficiency , then it can be replaced. Whether to change the filter cloth or not depends on the filtering effect of the filter press and the company's requirements for the moisture content of the sludge or the solid content of the mud cake. If the requirements for the moisture content of the sludge are not very strict and a slightly higher water content of the filter cake is acceptable, then the filter cloth can still be used; otherwise, if the filter cloth is more blocked, the mud cake cannot be squeezed out or the liquid cannot seep out. , it must be replaced immediately. Combined with many years of user experience, the average service life of a piece of filter cloth is 4-8 months, and it also depends on the frequency of use of the machine and the properties of the filter material. For some
How to choose a filter press? Come with me!

Filter press can be divided into a variety of categories according to different structures, pressing methods, outsourcing materials, etc., when the user chooses, but also according to the filter material properties, area, productivity and so on to choose the right filter press. And the accessories of the filter press are also very important. Different filter press matches different special pump of the filter press, and the choice of the press cloth is also exquisite. Because of the particularity of products in some factories, there may be some large particles of solid slag in the discharge sludge, so it is necessary to filter the large particles of sludge before the feed pump. Because the sludge into the filter press is retained in the filter room composed of the filter plate cloth for pressing and filtering, if the filter contains hard, large volume of solid particles, then it is likely to cause damage to the filter plate of the filter press. In the filtration process, so hard and volume of solid particles will accumulate in the chamber, with more and more solid particles, a variety of hard particles piled up together, plus the filter press automatically to the filter plate to provide a filter cake extrusion force, we all know that the force is mutual, plus hard particles in the filter chamber uneven distribution, This will also cause the filter press filter plate easy to damage. The damage here is only in the process of using the filter press, the filter plate inadvertently, the pressure deformation of the filter plate, uneven, or the height of the filter plate edge and boss is not consistent, or the edge is directly worn. The above damaged filter plates are not easy to see, if the appearance of the filter plate does not look damaged and other filter plates are used together, in the operation of the filter press, the equipment to provide strong pressure to the filter plate, and t
