Van-type filter press for preventing mud cake from sticking to filter cloth and method for separating from mud cake

Abstract

The invention relates to the technical field of van filter press, in particular to a van-type filter press for preventing mud cake from sticking to filter cloth and a method for separating from mud cake. The press comprises a frame, the upper end of the filter cloth is fixed under the action of the force plate, the upper end of the filter cloth can be driven away from the filter plate through thestress plate, at the same time, under the mutual cooperating of the elastic force of the tension spring, the stress plate can be driven to vibrate, and the stress plate can drive the filter cloth to vibrate, so that the mud cake remaining on the filter cloth, which is difficult to fall off, can be vibrated and separated, and at the same time, the sludge remaining in the gap of the filter cloth canbe vibrated to fall off, so as to ensure the filtering effect of the filter cloth; under the action of the vibration pressing plate, the stress plate can be quickly pushed, so that the tension springgenerates vibration with larger amplitude, which is beneficial to improving the vibration amplitude of the filter cloth, thus ensuring that the residual mud cake on the filter cloth can fall down, thus reducing and avoiding manual cleaning of the mud cake, effectively reducing the manual workload, and increasing the efficiency of filtering sludge.

Description

technical field [0001] The invention relates to the field of box-type filter presses, in particular to a box-type filter press for preventing mud cakes from sticking to filter cloth and a method for separating from mud cakes. Background technique [0002] The filter press is a machine that applies mechanical force on one side of the filter medium to achieve filtration. The chamber filter press is composed of two adjacent concave filter plates, and a filter chamber is formed between the adjacent filter plates. The sludge is passed into the filter chamber to form a higher pressure in the filter chamber, and the water is filtered out under the action of the pressure to form a mud cake, and finally the filter plate is separated to make the mud cake fall, but when the sludge to be filtered has a high viscosity At this time, the mud cake is often difficult to fall or cannot fall completely, and some mud cakes remain on the filter cloth, resulting in the need to manually clean the ...

AI Technical Summary

Problems solved by technology

[0003] The present invention provides a chamber filter press that prevents mud cakes from sticking to the filter cloth to overcome the existing technology. When the sludge to be filtered has a high viscosity, the mud cakes are often difficult to fall or cannot be completely dropped, and some mud cakes Residues on the filter cloth, resulting in the need for manual cleaning of the mud cake
