The utility model discloses a can dismantle pressure filter of filter cake fast, including compressing tightly the base, thrust base and two establish at the thrust base and compress tightly the crossbeam between the base, two crossbeams are in the side of controlling that compresses tightly base or thrust base, it includes the telescopic ejector pin and fixes the pressure strip on the ejector pinto compress tightly the base, the thrust base includes rigid's thrust plate, be equipped with a plurality of filter frame subassemblies and filter cloth on two crossbeams in turn, the filter frame subassembly at both ends around thrust plate and pressure strip are connected respectively, the left and right sides of each filter frame subassembly is equipped with is convenient for the crossbeam bearing in one's ear, it draws the area to be connected with on in one's ear with every adjacent two of one side, but pull area elastic extension to regular length. The efficiency of unload is improved worker labor intensity, especially operator need not frequent contacting equipment, the potential safety hazard of stopping probably to exist with the reduction. This utility model is used for the pressure filter field.
