[0002] Sedimentation tank is a kind of structure that uses sedimentation to remove suspended matter in water and is a device for purifying water. It uses the natural sedimentation of water or the effect of coagulation and sedimentation to remove suspended matter in water. Sedimentation tanks are divided into horizontal sedimentation tanks and vertical sedimentation tanks according to the direction of water flow. The sedimentation effect is determined by the flow rate of water in the sedimentation tank and the residence time of water in the tank. Sedimentation tanks are widely used in sewage treatment. In order to pursue efficient treatment of sediment, sedimentation tanks usually use the combination of transmission rods and mud scrapers to promote the rapid concentration of sediments in one place, so as to achieve the effect of efficient centralized treatment of sediments.

[0003] Although the above method is convenient for centralized treatment of sediment, it is inevitable that there are still some shortcomings in the actual use process. For example, the device lacks a transmission mechanism, so that the sewage water mixing and sediment concentration are independently driven, resulting in a large energy consumption. In order to avoid the above problems, a high-efficiency sedimentation tank is proposed to solve the existing problems. Utility Model Content
