Filter press for mine sludge treatment

The invention relates to a mine sludge treatment filter press which comprises a rack, a filter plate and a plate pulling trolley are horizontally and slidably connected to the rack, meanwhile, a water inlet pipeline, a water outlet pipeline, an extrusion plate and a hydraulic cylinder are arranged on the rack, a clamping block is slidably connected to the plate pulling trolley, a clamping groove is formed in the clamping block, and the clamping groove is communicated with the clamping plate. Two adjacent filter plates can be clamped and locked and can be driven to slide, a cleaning mechanism is arranged on the plate pulling trolley, the cleaning mechanism is located between the two clamping blocks, when the filter plates are clamped and locked through the plate pulling trolley, the cleaning mechanism cleans the faces, close to the cleaning mechanism, of the filter plates, the cleaning function is achieved, and the cleaning mechanism is integrated on the plate pulling trolley. The low-pressure filter has the e
