[0002] The plate-and-frame filter press is a filter device frequently used in the production of traditional Chinese medicine. The plate-and-frame filter press is formed by arranging plates and frames alternately. Filter cloth is arranged on both sides of the plates. A compression device is used to compress the plates and frames, thereby forming a compression filter chamber between the plates and frames. A small hole is formed in the same position of the upper end of the plate and frame. After compression, the small hole becomes a passage, and impurities enter the compression filter chamber through the passage. The surface of the plate is engraved with a groove, and a hole is drilled at the lower end of the plate for discharging filtrate. Under pressure, the filtrate is discharged from the filter press through the filter cloth along the groove and the hole, thereby dehydrating. After dehydration, the impurities are stored in the compression filter chamber in the form of a cake. Then, the plates and frames are separated, and the mud cake falls off.

[0003] However, the plates and frames still need to be cleaned after the mud cake falls off, and residual soil and other impurities need to be cleaned. Therefore, the existing plate-and-frame filter press is cleaned by a filter cloth flushing vehicle after the plates and frames are separated, which is low in efficiency and greatly affects the efficiency.
