a filter press

Abstract

The invention discloses a filter press, aiming to provide a filter press with a shorter fuselage, less water content in the filter residue, saving cleaning water, and favorable working environment to keep clean and dry. Its structure is a closed filter room composed of frame, cover plate, bottom plate, front plate, filter plate and filter cloth. The frame is composed of rear plate and left and right grid plates; rear plate, cover plate, front plate and bottom plate Both have long slots, and there are long strip bosses and long strip hollow slots in the grid plate. The front plate is fixed on the frame with screws, and the filter cloth is covered on the filter plate; there is extrusion in the compartment between the two filter plates. The slag discharge plate can further squeeze and dry the filter residue and push the filter residue out of the filter room; the flushing pipe installed on the back plate and passing through the back plate to the filter room can clean the filter room and filter cloth.

Description

technical field [0001] The invention relates to a solid-liquid separation machine, especially a plate-frame and box-type filter press machine for pressure filtration. Background technique [0002] In the existing plate-frame and box-type filter press, when the filtration is completed, the filter plate and filter frame need to be loosened, the filter residue is removed, and the filter cloth is washed, so the frame is very long; the washing process is open, and the working environment is not easy to keep clean and dry , the large water consumption is not conducive to recycling; in order to reduce the moisture content of the filter residue, the diaphragm filter plate with a short service life is often squeezed with compressed air, so that the diaphragm expands and squeezes the filter residue. Contents of the invention [0003] The present invention overcomes the above-mentioned deficiencies of the prior art, and provides a filter residue and filter cloth flushing that can be ...
