Problems solved by technology

[0002] The traditional fully automatic filter press is a frame composed of a thrust plate, a main beam, a pressing device and a pulling plate device. The filter unit is composed of a filter cloth; the supporting system is composed of a hydraulic station, a slurry pump, a peripheral pipeline and an electrical control system; when the filter starts, the filter slurry is fed by the thrust plate under the push of the feed pump. The filter press enters each filter chamber through the inlet, and the filter press uses the pressure generated by the feed pump to separate the solid from the liquid. Due to the action of the filter medium (filter cloth), the solid remains in the filter chamber to form a filter cake, and the filtrate is discharged from the nozzle or the outlet valve. ; If the filter cake needs to be washed, the washing water can be passed through the washing port on the thrust plate to wash the filter cake; if the filter cake with a low moisture content is required, compressed air can be passed through the washing port to penetrate the filter cake layer, Part of the water in the filter cake is blown out; after the filtration is finished, the pressing device releases the pressing plate, and the plate pulling device pulls the filter plates apart one by one, and the filter cake falls off from the opened filter chamber under the action of gravity, and all the filter cakes in the filter chamber After the unloading is completed, a working cycle is completed; in the unloading process of the traditional filter press, the filter unit is unloaded by opening the plates one by one, and the chain pull plate is unloaded, and the structure is complex, resulting in long unloading time and low efficiency; therefore , need a multi-stage unloading filter press
