Anti-blocking sludge discharge device for sewage treatment

Abstract

The invention relates to the technical field of sewage treatment, and discloses an anti-blocking sludge discharge device for sewage treatment. The device comprises a corrosion-resistant film, a base is fixedly arranged below the corrosion-resistant film, the base comprises a reinforcing layer, a wear-resistant layer and a protective layer, the protective layer is tightly attached to the upper portion of the reinforcing layer, the wear-resistant layers are arranged below the protective layer in parallel, a fixing groove is fixedly formed in the outer surface of the base, a shell is connected to the upper portion of the fixing groove, a rotating seat is fixedly installed on the outer surface of the shell, and the rotating seat comprises a rotating shaft, stirring blades, a blade seat, a shaft seat and a bearing seat. According to the anti-blocking sludge discharge device for sewage treatment, through cooperation of the rotating seat, a filter plate, a reset spring, a limiting seat, a scraping strip, the stirring blades and a connecting rope, the device can well treat sewage, the possibility of blocking is reduced, the utilization rate of the sewage is increased, excessive waste of a water source is avoided, and meanwhile the service life of the device is prolonged.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an anti-clogging mud discharge device for sewage treatment. Background technique [0002] According to the classification of sewage sources, sewage treatment is generally divided into production sewage treatment and domestic sewage treatment. Production sewage includes industrial sewage, agricultural sewage and medical sewage, while domestic sewage is sewage generated in daily life, which refers to various forms of inorganic substances and A complex mixture of organic matter, including: floating and suspended large and small solid particles; colloidal and gel-like diffusion; pure solution, according to the nature of water pollution, there are two types of water pollution: one is natural pollution; The first type is man-made pollution. At present, man-made pollution is the most harmful to water bodies. Water pollution can be mainly divided into three categories: chemical ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides an anti-clogging sludge discharge device for sewage treatment, capable of scraping off the sludge on the filter plate, reducing the number of removal and cleaning of the filter plate, thereby reducing the The degree of wear and tear of installation and disassembly, and the addition of a manpower stirring device at the bottom can prevent a little sludge from clogging due to sedimentation, and facilitate the timely discharge of sludge, etc., which solves the problem of anti-clogging sludge discharge devices for sewage treatment. It is very inconvenient to install a filter in the pipeline, and then take out the filter regularly for cleaning. In addition, during the process of filtering sludge with the filter, the mesh holes on the filter are easily blocked, affecting water flow, and it is not convenient to clean the sedimentation tank. The sludge at the bottom is stirred, which is conducive to stirring the stubborn sludge and facilitating the sludge discharge work; the problem of poor anti-blocking effect of the sludge discharge device
