A filter cloth cleaning device for a filter press

Abstract

The invention relates to a filter press and in particular relates to a filter cloth cleaning device for a filter press. The device comprises a cleaning moving rack, a cleaning lifting rack, a detection plate, position sensors and limit switches, wherein the structures of the cleaning moving rack and the cleaning lifting rack are greatly different from those in the prior art; more than eight groups of cleaning parts are arranged in the cleaning lifting rack; the position sensors are arranged at four corners at the bottom of the cleaning lifting rack; and the limit switches are respectively arranged above and below the cleaning moving rack along the Z direction, so that more than eight groups of filter plates are automatically cleaned. Compared with the prior art, the filter cloth of multiple filter plates can be cleaned at a time, the cleaning efficiency is high, and the consumption of cleaning water is saved; the four bottom points of the cleaning moving rack are positioned, the start and stop positions of a cleaning vehicle are accurate, the phenomenon that the cleaning pipe is collided with the filter plates is avoided, and the failure rate is low; and moreover, full-automatic operation of the cleaning device is realized, manual intervention is not needed, and the manual cost can be reduced.

Description

technical field [0001] The invention relates to a filter press, in particular to a filter cloth cleaning device for a filter press. technical background [0002] The filter press uses filter cloth as the filter medium and is an intermittent pressurized filter. It has the advantages of small footprint per unit area, strong adaptability to materials, and high filtration pressure. It is widely used in the field of solid-liquid separation. The material is injected into the filter chamber through the slurry pump, the liquid passes through the filter cloth to form a filtrate and is discharged, and the solid particles are trapped by the filter cloth to form a filter cake, which is unloaded after a series of operations such as pressing and air drying. Due to the difference in physical properties such as material particle size and viscosity, after the filter press has been working for a period of time, there will be varying degrees of clogging of the filter cloth, resulting in poor a...

AI Technical Summary

Problems solved by technology

Due to the difference in physical properties such as material particle size and viscosity, after the filter press has been working for a period of time, there will be varying degrees of clogging of the filter cloth, resulting in poor air permeability of the filter cloth and inability to drain fluid smoothly, which in turn makes the filter press Filtration cycle side length, reduced work efficiency

The existing filter cloth cleaning technology adopts the cleaning driving method installed above the filter press. The problems of this technology are that the cleaning time is long, the efficiency is low, and the cleaning vehicle travels and the positioning failure rate is high.
