Cleaning device for filter belt of sludge electroosmosis dewatering machine

Abstract

The invention aims to provide a cleaning device for a filter belt of a sludge electroosmosis dewatering machine. The cleaning device comprises a dry washing device and a wet washing device, wherein a partition plate is arranged between the dry washing device and the wet washing device; a temperature control device, a scrubbing device and a dust collection device are arranged in a box body; the scrubbing device comprises a plurality of rolling brushes and a gas guide pipe; the rolling brushes comprise rotating rollers and a plurality of bristles; the rotating rollers adopt hollow structures, and a plurality of air outlet holes are formed in the rotating rollers; a plurality of spraying heads are arranged on the inner side of an upper cover in the box body of the wet washing device; a sewage collection tank is arranged at the lower part of a lower cover of the box body. The cleaning device has the beneficial effects that the dry washing device and the wet washing device are combined, so that most of solid particles fall off from the filter belt through the dry washing device by the combination of the high-pressure air and the rolling brushes and then enter the wet washing device; the spraying brushes are used for scrubbing off the sludge retained on the filter belt; by the step-by-step cleaning mode, the sludge on the filter belt can be effectively removed; the cleaning efficiency is high, water is saved, and the cleaning cost is reduced.

Description

technical field [0001] The invention relates to a cleaning device, in particular to a cleaning device for the filter belt of a sludge electroosmosis dehydrator. Background technique [0002] Sludge, as a solid pollutant produced by urban sewage treatment plants, is an extremely complex heterogeneous body composed of organic matter, inorganic salts, microorganisms, and parasite eggs. Most urban sewage treatment plants use activated sludge process to treat sewage. The electroosmotic sludge dewatering machine uses the phenomenon that sludge particles and water molecules separate and move in opposite polar directions to dehydrate. The sludge high-dry dehydration equipment that removes part of the interstitial water and adsorbed water can reduce the moisture content of the activated residual sludge to below 60%. [0003] The positive and negative poles of the electro-osmotic sludge dewatering machine are equipped with filter belts. After the electrodes are energized, the sludge...

AI Technical Summary

Problems solved by technology

[0003] The positive and negative poles of the electro-osmotic sludge dewatering machine are equipped with filter belts. After the electrodes are energized, the sludge particles move, the water passes through the filter belts to form filtrate and is discharged, and the solid sludge is trapped by the filter belts to form filter cakes. The electro-osmotic sludge dewatering machine runs After a period of time, there will be different degrees of clogging of the filter belt, resulting in poor air permeability of the filter belt and inability to drain fluid smoothly, thereby reducing the working efficiency of the sludge electroosmosis dewatering machine
