A sludge filter press and its processing method

Abstract

The invention discloses a sludge filter press, which comprises a frame on which several plate frames are slidably arranged, and an oil cylinder for driving the plate frame to slide on the frame is installed at one end of the frame, the plate frame includes an outer Frame, the inner side of the outer frame is fixed with a pressure plate, the edge of one side of the outer frame is fixed with a filter plate, a number of filtrate holes are evenly arranged on the filter plate, filter cloth is installed on the outer side of the filter plate, and installation grooves are arranged on the edge of the filter plate. There are several threaded holes and a cleaning liquid socket evenly arranged inside, and the first through hole corresponding to the threaded holes is arranged on the filter cloth, and the edge of the filter cloth is crimped in the installation groove by the rubber tube, and the opening of the rubber tube The side wall of the rubber tube is provided with several liquid outlet holes, and the side of the frame that is not fixed with the filter plate is fixed with a rubber sealing strip. The invention can improve the deficiencies of the prior art, prolong the service life of the filter cloth, and facilitate the disassembly and replacement of the filter cloth.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a sludge filter press and a treatment method thereof. Background technique [0002] Sludge filter press is a device for dehydrating sludge with high water content. After dehydration, the water content of the mud cake is reduced, which is convenient for transportation and reuse. There are many types of sludge filter presses, among which plate and frame filter presses are widely used due to their high dehydration rate. The plate and frame filter press realizes the separation of sludge and water through the filter cloth in the plate and frame. During use, the filter cloth will be damaged and polluted, which requires replacement of the filter cloth, but because the filter cloth is easy to be separated from the plate The frame and the remaining sludge are stuck together, which makes it inconvenient to disassemble and replace. At the same time, it is easy to cause la...

Problems solved by technology

The plate and frame filter press realizes the separation of sludge and water through the filter cloth in the plate and frame. During use, the filter cloth will be damaged and polluted, which requires replacement of the filter cloth, but because the filter cloth is easy to be separated from the plate The frame and the remaining sludge are stuck together, which makes it inconvenient to disassemble and replace. At the same time, it is easy to cause large-scale damage to the filter cloth during disassembly, making the filter cloth unable to be recycled and reused.
