Clearing device for residual filter cakes of filter cloth

Abstract

The invention discloses a clearing device for residual filter cakes of a filter cloth. The clearing device comprises a rack, brushes and high-pressure nozzles, the clearing device is further internally provided with a plurality of symmetrical V-shaped puckering mechanisms, the puckering mechanisms comprise upper layer puckering rollers with elastic supports, and lower layer puckering rollers withelastic supports, the faces, in contact with the upper surface of the filter cloth, of the upper layer puckering rollers are arranged as convex faces, the faces, in contact with the lower surface of the filter cloth, of the lower layer puckering rollers are arranged as concave faces, and the puckering mechanisms, the brushes and the high-pressure nozzles are all mounted in the rack. By using the clearing device, when the filter cloth advances, a plurality of sets of approximately continuous puckered textures are generated on the surface of the filter cloth and the filter cloth is not off tracking, a residual filter cake layer on the filter cloth is crushed by squeezing and powdered, under the effect of the brushes, most of the powdered residual filter cakes are discharged out of the filtercloth, the filter cloth is washed with water by the high-pressure nozzles, the residual filter cakes are discharged out of the filter cloth in time, thus the effect of deeply clearing the filter cloth is achieved, the problem that the filter cloth is plugged by materials and consequently is difficult to clear is solved, and breathability of the filter cloth is regenerated.

Description

technical field [0001] The invention belongs to the technical field of filter cloth cleaning, and in particular relates to a device for cleaning residual filter cakes of filter cloth. Background technique [0002] Filter cloth can be used for solid-liquid separation of materials. After solid-liquid separation and discharge, the filter cloth will generally be washed with high-pressure water to remove fine particles in the filter cloth, thereby regenerating the air permeability of the filter cloth. The filter cloth enters the next cycle. [0003] Due to the different characteristics of materials and different working conditions, some materials clog the filter cloth seriously, the air permeability of the filter cloth is poor, the operation performance of the equipment decreases, and in severe cases, the entire filter cloth collectively fails. For example, if the temperature drops too fast, the filtrate will form crystals on the surface of the filter cloth; the chemical propert...

AI Technical Summary

Problems solved by technology

[0004] In view of this, the present invention expects to provide a device for cleaning filter cloth residual filter cake, in which a plurality of symmetrical V-shaped wrinkle mechanisms, cleaning brushes, and high-pressure nozzles are set. When the filter cloth travels along the length direction, Multiple groups of approximately continuous wrinkled textures will be produced on the surface of the filter cloth, and the filter cloth will not deviate, and the residual filter cake layer on the filter cloth will be crushed and pulverized. The filter cake will be mostly discharged out of the filter cloth, and then the surface of the filter cloth will be washed with high-pressure water through the high-pressure nozzle, and the residual filter cake will be discharged out of the filter cloth in time to achieve the effect of deep cleaning of the filter cloth , so as to solve the problem that the material clogs the filter cloth seriously and is difficult to clean, so that the air permeability of the filter cloth can be regenerated
