Elastic pressing filter plate, filter pressing assembly and filter press for electroosmosis high-pressure sludge

The utility model provides an elastic pressing filter plate, a filter pressing assembly and a filter press for electroosmosis high-pressure sludge. The elastic pressing filter plate comprises a filter plate body and a plate frame, the front face of the filter plate body is concave, springs which can make the plate frame and a base plate elastic are arranged between the plate frame and the base plate, and cathode conductive filter screens connected with cathode copper bars are simultaneously arranged behind filter cloth of the filter plate or a cathode conductive filter screen connected with the cathode copper bars and an anode plate connected with anode copper bars are arranged behind the filter cloth of the filter plate, so that a relatively sealed sludge storage cavity with an electroosmosis function is formed. By means of the elastic pressing filter plate, the filter pressing assembly and the filter press for the electroosmosis high-pressure sludge, when a ton of sludge with 80% moisture content is disposed by a hydraulic device, the energy consumption is lowered to 70 kwh, the moisture content of the sludge can be quickly reduced below 30%, and compared with a common diaphragm filter press, the dehydration efficiency is increased by two times.
