The filter press models can be divided into: plate and frame filter press, box filter press, box diaphragm filter press, belt filter press and screw stacker, etc. Belt filter presses, centrifuges and screw stackers, etc., are of the continuous working type without interruption. Plate and frame filter press, box filter press, and diaphragm filter press belong to intermittent pressurized filtration equipment.
The filter press is used for solid-liquid separation of various suspensions. It relies on a compacting device to compress the filter plate, and then pumps the suspension into the filter chamber to achieve the purpose of separating solid particles and liquid materials through the filter cloth.
The structure of the whole machine is simple, the separation effect is good, the use is convenient, the application range is wide, and it is widely used in the solid-liquid separation of various suspensions in the fields of metallurgy, environmental protection, electroplating, breeding manure, coal washing, inorganic salt, mining, alcohol, petroleum, chemical industry, dyestuff, metallurgy, medicine, food, textile, printing and dyeing, papermaking and sewage treatment.
2. The filter press is composed of a frame, a hydraulic system, a compression plate, a thrust plate, a filter plate, and a filter cloth. The detailed functions can be divided into: 1) Compression methods: manual compression, mechanical compression, and hydraulic compression. Hydraulic pressure can be divided into hydraulic self-protection, manual locking, and manual hydraulic pressure.
2) Automation: manual, semi-automatic and fully automatic
3) Liquid outlet method: open flow, dark flow, light and dark common
4) Washing method: forward washing, reverse washing (one-way washing, two-way washing, two-way cross washing, side washing)
5) Feeding method: upper corner feeding, upper middle feeding, middle feeding, lower corner feeding
6) Cleaning method of filter cloth and filter plate: manual, automatic water washing
