Technical Field

[0001] The utility model relates to the technical field of aeration tank equipment, in particular to an aeration tank with a silt removal function. Background Art

[0002] Aeration tanks are biochemical reactors designed according to the characteristics of microorganisms. The degree of degradation of organic pollutants mainly depends on the aeration reaction conditions designed by people. In the prior art, a large amount of sludge adheres to the bottom of the aeration tank after long-term use. The sludge adheres to the inner wall of the aeration tank and is difficult to clean. At the same time, when the sludge is discharged, it is easy to cause blockage, and it does not have the function of guiding the discharge of sludge.

[0003] For example, an aeration tank disclosed in an authorized patent document with application number CN201621470437.2 includes a tank body and an aeration pipe, wherein an air outlet is provided on the aeration pipe, and the aeration pipe has an air inlet and a plurality of air outlets. Oxygen enters the aeration pipe through the air inlet and then enters the tank body through the air outlet to contact the liquid in the tank body. The aeration pipe rotation mechanism drives the aeration pipe to rotate. Beneficial effects of the utility model: 1. In the aeration tank of the utility model, the aeration pipe can rotate while delivering oxygen to the tank body, thereby increasing the turbulent flow speed of the liquid and improving the aeration efficiency; 2. In the aeration tank of the utility model, a radially movable stirring arm is provided to stir the liquid in the tank body, thereby further enhancing the turbulence of the liquid and further improving the aeration speed.

The silt adheres to the inner wall of the aeration tank and is difficult to clean, and there is no function to guide and discharge the silt. Therefore, we need to provide an aeration tank with a silt removal function. Utility Model Content
