Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a sewage treatment silt removal device. Background Art

[0002] During the crushing and rinsing process of refined cotton production, a certain amount of reducible industrial wastewater is generated. In the sewage treatment process, sedimentation tanks are one of the main equipment commonly used. Sedimentation tanks are used to achieve solid-liquid separation to remove sludge and suspended matter. The bottom of the sewage sedimentation tank commonly used at present is in the shape of a funnel. The silt is scraped to the center of the bottom by the silt removal plate at the bottom of the tank, and then the silt is pumped out by the silt pump to achieve silt removal. This silt removal method is difficult to completely remove the silt at the bottom. The silt that is not completely removed tends to adhere to the bottom of the sedimentation tank, accumulate and become thicker, and even clump, making subsequent cleaning more difficult. In severe cases, the silt removal plate used for removal will be damaged, thereby affecting the normal operation of the sedimentation tank. In response to such situations, we have proposed a sewage treatment silt removal device. Utility Model Content
