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...

The invention discloses a filter press and aims at providing a filter press which is short in body, low in filter residue moisture content, capable of saving cleaning water and facilitating clean and dry keeping of an operating environment. The filter press is a closed filter chamber structurally consisting of a rack, a cover plate, a base plate, a front plate, filtering plates and a filtering fabric, the rack consists of a rear plate, a left lattice plate and a right lattice plate, the rear plate, the cover plate, the front plate and the base plate are provided with long grooves, elongated bosses and elongated transparent grooves are formed in the lattice plates, the front plate is fixed to the rack by using screws, and the filtering fabric covers the filtering plates. A residue extruding and discharging plate is arranged in a partition chamber between the two filtering plates and can further extrude, dry and push filter residues out of the filtering partition chamber. A flushing pipe installed on the rear plate and penetrating through the rear plate to the filtering partition chamber can clean the filtering partition chamber and the filtering fabric.
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 ...
