Sludge removal device of sewage treatment tank

Abstract

The invention discloses a sludge removal device of a sewage treatment tank. The sludge removal device comprises a fixing rack. Fixing protrusion blocks are designed to be conical, the lower end surfaces of the fixing protrusion blocks and the lower end surface of a sludge removal device body are located on the same horizontal plane, and due to the structures, the movement is stable without affecting the work of the sludge removal device body; by fixing a drainage plate to the upper end of the sludge removal device body, openings of first water spraying holes are titled to face the sludge removal device body, and due to the structures, washing and softening of sludge are more suitable to actual circumstances; a first fixing rod, a second fixing rod and a third fixing rod are arranged in thevertical direction of the sludge removal device body in sequence, a movable scraper plate is in flexible connection with the first fixing rod, second water spraying holes are mutually staggered withthe second fixing rod and the third fixing rod, fixed scraper plates on the second fixing rod are tilted opposite to fixed scraper plates on the third fixing rod, and when the novel structure is adopted, the movable scraper plate cooperates with the fixed scraper plates to more quickly remove the sludge.

Description

technical field [0001] The invention relates to the related technical field of sludge treatment, in particular to a sludge removal device for a sewage treatment tank. Background technique [0002] In recent years, the discharge of urban domestic sewage has become the main pollution source of urban water in China. Urban domestic sewage treatment is the top priority of urban water conservation and environmental protection at present and in the future. This requires us to regard the construction of domestic sewage treatment facilities as a city The important content of the infrastructure is to be grasped, and it is an urgent matter. However, the current sewage treatment tanks have high production costs and poor treatment effects, and the key link in sewage treatment is sludge treatment. Incineration is to fully burn the combustible components in sludge at high temperatures, and finally become stable ash. The sludge treatment link is to process the sludge in the sewage step by ...

AI Technical Summary

Problems solved by technology

However, the existing sludge treatment devices are relatively expensive to build, and the effect is poor, and the dried sludge after burning is more likely to adhere to the inner wall of the sewage treatment tank. For this situation, most of the actual operation methods are through High-pressure water guns are used to flush the sludge to soften it and then remove it. However, this method not only wastes manpower and material resources, but also takes a long time to process, which affects production efficiency. Therefore, we propose a sludge removal device for sewage treatment tanks to solve the problem. above question
