The automatic sand washing pressure filter is made of high-quality carbon steel by optimized design and welding, and the beams made of hot-rolled structural steel with one-time molding structure, which has been treated to eliminate internal stress, mechanical rust removal ST2 grade, and the main welding parts treated by high-speed airflow shot blasting machine sandblasting. It has excellent wear resistance, strong adhesion of the coating, low shrinkage, high mechanical strength, coating integrity, no pinholes, good electrical insulation performance, high solid content, and very little paint volatilization, which meets the requirements of environmental protection; the filter plate made of TPE elastic body alkali-free glass fiber polypropylene, which has enhanced the toughness and rigidity of polypropylene, and also has the elasticity rubber diaphragm, which is solid and reliable, not easy to fall off, and has a long service life. (Corrosion resistance, acid resistance, alkali, salt resistance, non-toxic and tasteless) can withstand clamping force 25 Mpa, the hydraulic system's cylinder adopts precision boring sealing pipe, the reaches: IT7 grade; the automatic pull plate discharge system adopts low energy consumption small power frequency conversion speed motor, energy saving and environmental protection. The transmission torque is increased through the reducing motor. The frequency conversion motor has a wide range of speed regulation, which can be adjusted arbitrarily between 20HZ-60HZ, gear chain transmission,ying chain driving, mechanical hand pull plate; the automatic pull plate filter press adopts PLC control, which can perform various operations on the filter press (such as filter plate cl, loosening the filter plate, pulling the filter plate), and can automatically operate the control; the main functions include: automatic clamping and loosening, automatic high pressure un, automatic pressure maintaining, automatic pressure supplementing, automatic pull plate, automatic cake discharge, pause, automatic operation, etc. The whole process control can be automatically controlled by the program can be manually operated. The action process mainly includes: first start the hydraulic system, pressurize the filter press, and automatically stop when the pressure rises to the set pressure. open the feed pump and the feed pipeline valve, and inject the slurry into the filter press. Filter through the filter cloth, the material residue is retained in the filter press and the filtrate flows into the clear water tank through the dark or bright outflow pipe. When the filter press is full of filter cake, the feed pump stops, and the on the feed pipeline is closed. Then loosen the filter press pressure plate, and the pressure plate stops at the limit position. After the filter cake is discharged, the pressure system started again, and the filter press is pressed. After the filter plate is pressed, the second feeding operation is carried out. The operation is convenient and the performance is stable It is widely used in chemical industry, light industry, petroleum, pharmaceutical, food, resource development, metallurgical coal, environmental protection, waste (waste): chemical waste water, metallurgical waste water, electroplating waste water, leather waste water, printing and dyeing waste water, pharmaceutical waste water, breeding waste water, slaughter water, sand washing field waste water, building pile driving waste water, stone cutting waste water and other fields, which is deeply welcomed by users. Our company produces various models of box filter press, hydraulic filter press, diaphragm filter press, fully automatic filter press and filter press accessories, with reliable quality and complete specifications.
Filter plate materials are divided into cast iron, reinforced polypropylene, glass fiber polypropylene, etc.
There are various forms fluid flow: open flow, closed flow, washable, non-washable, central feed, corner feed, etc.
(5)Filter plate clamping methods include: clamping and hydraulic cylinder clamping. For filter presses with special requirements, solutions can be negotiated separately.
