when the filter cake needs to be washed, there are sometimes unidirectional washing and bidirectional washing, undercurrent unidirectional washing and bidirectional washing.
The filter mechanism is composed of a filter plate, a filter frame, a filter cloth, and a press membrane. Both sides of the filter plate are covered with filter cloth. When a press membrane needs to be configured, a set of filter plates is composed of a diaphragm plate and a side plate. Both sides of the base plate of the diaphragm plate are covered with a rubber diaphragm, the outer edge of the diaphragm is covered with a filter cloth, and the side plate is an ordinary filter plate. The material enters each filter chamber from the feed hole on the thrust plate. The solid particles are trapped in the filter chamber because the particle size is larger than the pore size of the filter medium (filter cloth), and the filtrate flows out from the outlet hole below the filter plate. When the filter cake needs to be squeezed out, in addition to squeezing with a diaphragm, compressed air or steam can also be introduced from the washing port, and the air flow flushes the water in the filter cake to reduce the water content of the filter cake.
