  Working principle of cast iron plate and frame filter press The plate and frame filter press consists of a set of filter chambers arranged alternately through filter plates and filter frames. There are grooves on the surface of the filter plate, and the protruding parts are used to support the filter cloth. There are through holes on the corners of the filter frame and filter plate, which form a complete channel after assembly, and can pass into the suspension, washing water and lead out the filtrate. There are handles on both sides of the plate and frame to support the beam, and the plate and frame are pressed by the pressing device. The filter cloth between the plate and the frame acts as a sealing gasket. The suspension is hydraulically pumped into the filter chamber by the feed pump, and filter residue is formed on the filter cloth until the filter chamber is full. The filtrate passes through the filter cloth and flows along the groove of the filter plate to the channel at the corner of the plate frame, where it is discharged concentratedly. After the filtration is completed, the filter residue can be washed with clean water. After washing, sometimes compressed air is introduced to remove the remaining washing liquid. Then open the filter press to remove the filter residue, clean the filter cloth, re-press the plate and frame, and start the next working cycle. The plate and frame filter press is suitable for suspensions with high compressibility or nearly incompressible suspensions. The plate and frame are usually square, and the plate and frame are compressed by manual screw, electric screw and hydraulic pressure. Plates and frames are manufactured from materials such as wood, cast iron, cast steel, stainless steel, polypropylene and rubber. Plate and frame filter presses are used for the separation of solids and liquids

  Process and advantages of program-controlled automatic pull plate filter press for treating hospital wastewater The program-controlled automatic plate drawing and pressing machine is a widely used return and separation equipment, which can be used to treat various waste water, including lost water. It is convenient and has high treatment efficiency, and can effectively remove floating objects and waste water in waste water. Pollutants, so that it meets the rescue standards. The editor of Jungong will introduce the process and advantages of the program-controlled automatic pull-plate filter press to treat hospital wastewater. 1. Program-controlled automatic pull plate filter press process for treating hospital wastewater 1. Feeding: After preliminary treatment, the hospital wastewater flows into the hopper of the program-controlled automatic pull-plate filter press by pump or gravity. 2. Filtration: Wastewater is separated from solid and liquid by a filter plate. Suspended solids and pollutants are intercepted on the filter plate, and the clean water flows out after passing through the filter plate. 3. Washing: The filtered filter cake needs to be washed to remove the remaining dirt on the surface of the filter cake and ensure the quality of the effluent. The washing water is pumped into the filter cake and then flows out through the filter plate. 4. Dehydration: The washed filter cake needs to be dehydrated to reduce the moisture content and facilitate transportation and handling. Dehydration requires two steps of pressure filtration and extrusion. 5. Slagging: The dehydrated filter cake needs to be slagging, and the filter cake is di

  Advantages of program-controlled automatic pull plate filter press in treating hospital wastewater 1. Higher treatment efficiency: The program-controlled automatic pull plate filter press has a higher treatment efficiency, and can complete a large amount of solid-liquid separation work in a short time, improving the efficiency and treatment capacity of wastewater treatment. 2. The treatment effect is very good: the effluent quality of the wastewater treated by the program-controlled automatic plate filter press is high, which meets the relevant discharge standards and meets the environmental protection requirements. 3. Simple operation: The operation of the program-controlled automatic pull plate filter press is simple and convenient. It only needs to be operated according to the operation process, and the requirements for professional skills and knowledge are relatively low. 4. Easy maintenance: the program-controlled automatic plate filter press is easy to maintain, and equipment maintenance personnel can perform simple maintenance and repairs to prolong the life of the equipment. 5. Stable and reliable: the program-controlled automatic pull plate filter press adopts PLC control system, which has high stability and reliability, and the probability of failure during operation is very low The above is about the process and advantages of the program-controlled automatic pull plate filter press for treating hospital wastewater. In short, as a high-energy-efficiency, economical, stable, reliable, and effective equipment, the automatic plate-drawing machine can effectively treat
