Rotational living sewage aeration mechanism

Abstract

The invention discloses a rotational living sewage aeration mechanism which comprises a tank body, a fixing rack, a motor, a rotating shaft, aeration blades, an aeration disc, a main air conveying tube, a water discharge tube and a water inlet tube, wherein the fixing rack is fixedly connected with the top of the tank body; the motor is fixedly connected with the lower surface of the fixing rack; the rotating shaft is fixedly connected with a shaft extension end of the motor; a chute is formed in the side wall of the rotating shaft; a sliding block is arranged on the rotating shaft in a sleeved manner; aeration blades are fixedly connected with the left side and the right side of the sliding block; a driving gear is arranged at the lower end of the rotating shaft in a sleeving manner; three driven gears are distributed around the driving gear; an annular tooth groove is fixedly connected with the inner wall of the tank body; the aeration disc is arranged on a driven shaft in the sleeve manner; an air blower is fixedly connected with the left side wall of the fixing rack. Under the action of buoyancy, the aeration blades always float on a water surface, and surface sewage is aerated by using the aeration blades; air is conveyed to the rotating shaft and the driven shaft by using the air blower, and thus sewage at the bottom and in the middle can be aerated simultaneously.

Description

technical field [0001] The invention relates to sewage treatment equipment, in particular to a rotary domestic sewage aeration mechanism. Background technique [0002] The aeration tank is a structure that uses the activated sludge method for sewage treatment. A certain sewage residence time is provided in the tank to meet the oxygen required by aerobic microorganisms and the mixing conditions for full contact between the sewage and the activated sludge. The aeration tank is mainly composed of the tank body It consists of three parts, the aeration system and the water inlet and outlet. The pool body is generally made of reinforced concrete, and the plane shape is rectangular, square and circular. The existing aeration methods are mainly divided into blast aeration and mechanical aeration. First, the existing aeration tanks often have a single aeration mechanism, long aeration time, low aeration efficiency, and the ability to treat sewage needs to be improved, making it diffi...

[0002] The aeration tank is a structure that uses the activated sludge method for sewage treatment. A certain sewage residence time is provided in the tank to meet the oxygen required by aerobic microorganisms and the mixing conditions for full contact between the sewage and the activated sludge. The aeration tank is mainly composed of the tank body It consists of three parts, the aeration system and the water inlet and outlet. The pool body is generally made of reinforced concrete, and the plane shape is rectangular, square and circular. The existing aeration methods are mainly divided into blast aeration and mechanical aeration. The existing aeration tanks often have a relatively single aeration mechanism, long aeration time, low aeration efficiency, and the ability to treat sewage needs to be improved, making it difficult to meet people's growing sewage treatment needs.
