Description

Novel sludge bucket capable of being used for secondary sedimentation tank Technical Field The utility model belongs to the technical field of secondary sedimentation tanks, and particularly relates to a novel sludge hopper which can be used for a secondary sedimentation tank. Background In the sewage treatment process, a secondary sedimentation tank is an important link, and the secondary sedimentation tank has the main functions of clarifying, separating and concentrating the mixed liquor, and a sludge hopper in the secondary sedimentation tank is responsible for collecting and discharging the precipitated sludge. The traditional secondary sedimentation tank sludge hopper has a plurality of problems in the use process. On the one hand, the design of the sludge discharge structure is unreasonable, and the sludge discharge pipeline is easy to be blocked, so that the sludge discharge is unsmooth, the sewage treatment efficiency is influenced, for example, the size and the distribution of sludge discharge holes are unreasonable, the sludge discharge requirements of sludge with different properties cannot be met, and the sludge is easy to be accumulated in the pipeline. On the other hand, the performance of scraping mud subassembly remains to promote, and traditional mud scraping device is difficult to laminating two heavy pond bottoms and lateral wall well, and it is not good to scrape mud effect, and mud remains more, needs frequent clearance and maintenance. In addition, the existing sludge hopper has the defects in the aspects of automatic control and maintenance convenience, and is difficult to realize accurate control of sludge discharge and real-time monitoring of equipment operation states, so that the efficient and stable operation of a sewage treatment system is not facilitated. Disclosure of utility model Aiming at the defects of the prior art, the utility model aims to provide a novel sludge bucket for a secondary sedimentation tank, which solves the problems that sludge discharge is unsmooth and sewage treatment efficiency is affected due to unreasonable sludge discharge structural design and easy blockage of a sludge discharge pipeline on one hand, and solves the technical problems that the sludge scraping effect is poor, more sludge residues are caused and frequent cleaning and maintenance are required due to the fact that the performance of a sludge scraping assembly is to be improved and the traditional sludge scraping device is difficult to well attach to the bottom and the side wall of the secondary sedimentation tank on the other hand.
