Furthermore, the matching plate film increases the capacity of the matching filter plate, the protruding filter points on the edge of the film plate decrease gradually from the edge to the inner layer by layer until the filter points are flush with the filter point of the filter surface, and the filter points with the higher edge of the filter surface extrude the material and the flat plate in the filter chamber, so that the bending deformation of the periphery of the filter plate is prevented, and the service life of the filter plate is prolonged.

The utility model also provides a special sludge filter press, which uses the matched filter plates of the utility model to form an integrated mechanism, and consists of a thrust plate, a head and tail anti-corrosion plate, a plurality of matched filter plates, a pressure plate, a filter cloth, a hydraulic drive system, a pulling plate system, an electric appliance control system and the like; during feeding, the solid-liquid mixture is conveyed to each filtering chamber by the pump, the materials are intercepted to form filter cakes, and the filtrate is discharged from the liquid outlet holes at the lower two corners, so that the blind flow liquid discharge is realized, the liquid is not volatilized or leaked in a clicking manner, and the site is clean and tidy; the utility model discloses a pressure filter degree of automation is high, and the filter cake moisture content is low, long service life.

The utility model provides a pair of supporting filter plate of balance plate membrane increase-volume and corresponding sludge filter press have that it is fast, filter area increase, take off the cake easy, the filter cake moisture content is low, intensity is high, toughness is good, long service life's advantage.
