Sludge rubber crusher

Abstract

The sludge rubber crusher comprises a static mixer, a dynamic stirring tank, a belt type thickener, a first machine body and a second machine body, the static mixer is installed on a water inlet pipe opening in the bottom of the left end of the dynamic stirring tank, and the belt type thickener is located in the middle of the right side of the dynamic stirring tank; a first machine body and a second machine body are sequentially arranged on the right side of the belt thickener from top to bottom; the first machine body comprises a porous screen roller rotationally installed at the bottom of the right side of the first machine body. Compared with the prior art, the sludge gel breaker has good gel breaking and wall breaking effects on sludge which is complex in component and difficult to break and condition, when the sludge treated by the sludge gel breaker is flocculated again, the sludge pie reaction is thorough, the floccules are flourishing and firm, the sludge-water separation effect is good, the subsequent mechanical dehydration medicine consumption can be reduced, the sludge conditioning difficulty is reduced, lime does not need to be added, and the cost is reduced. The subsequent mechanical filter pressing time can be shortened, the production efficiency is improved, and the water content of a filter cake is reduced.

Description

technical field [0001] The invention relates to the technical field of sludge treatment, in particular to a sludge breaker. Background technique [0002] Sludge treatment is the process of reducing, stabilizing and harmlessly treating sludge. The higher the degree of sewage treatment, the more sludge residues will be generated to be treated, unless land treatment or sewage ponds are used Otherwise, general sewage treatment plants must be equipped with sludge treatment facilities. For modern sewage treatment plants, sludge treatment and disposal have become the most complicated and costly part of the sewage treatment system. However, there are still deficiencies in the existing sludge breakers: river and lake bottom mud, pile foundation mud, municipal sludge, industrial sludge, etc., often appear that the appearance of mud balls has been conditioned into flowers when conditioning and flocculating before mechanical dehydration However, because there are still many colloidal m...

Problems solved by technology

However, there are still deficiencies in the existing sludge breakers: river and lake bottom mud, pile foundation mud, municipal sludge, industrial sludge, etc., often appear that the appearance of mud balls has been conditioned into flowers when conditioning and flocculating before mechanical dehydration However, because there are still many colloidal mud groups inside the flocs that have not been completely separated, the process of gravity dehydration and extrusion dehydration is slow, and even mud leakage occurs. In the current mechanical dehydration process, in order to solve this Colloidal sludge, to improve the efficiency of sludge mechanical dewatering, generally adopts the method of adding lime to break the gel, but adding lime will lead to a higher pH value of the tail water, which is not conducive to the final disposal of the subsequent sludge cake
