Problems solved by technology

[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 water consumption is large, which 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

Embodiment Construction

[0012] The present invention will be further described below in conjunction with accompanying drawing:

[0013] figure 1 , figure 2 It is an embodiment of the present invention, first remove the front plate 16, put the bottom of the filter plate 22 on the boss of the grid plate 21, push the filter plate 22 to insert it into the long groove of the cover plate 3 and the rear plate of the frame 4 , and then the front plate 16 is fixed on the frame 4 with screws, the lower hydraulic cylinder 18 is started to press the bottom plate 6, and the front and rear hydraulic cylinders 19, 20 push the slanting block 5, and the slanting block 5 pushes the wheel 15 to fasten the claw 14 Base plate 6, shut down, front and rear hydraulic cylinders 18, 19, 20, open feed valve 2 to feed the filter chamber, open the filtrate end of two-way liquid outlet valve 23 simultaneously, carry out pressure filtration.

[0014] At the end of the filter press, stop feeding, start the upper hydraulic cylind...

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 ...
