Description

Technical Field

[0001] The utility model belongs to the technical field of aeration tanks, and specifically relates to an aerobic aeration tank lifting aeration device that can avoid shutdown for replacement. Background Technique

[0002] An aeration tank is a biochemical reactor designed according to the characteristics of microorganisms, and the degradation degree of organic pollutants mainly depends on the designed aeration reaction conditions. The aeration tank uses the activated sludge method for sewage treatment, providing a certain sewage retention time in the tank to meet the oxygen demand of aerobic microorganisms and the mixing conditions for sufficient contact between sewage and activated sludge. The aeration tank mainly consists of three parts: a tank body, an aeration system, and an inlet and outlet. The tank body is generally made of reinforced concrete, and the planar shape can be rectangular, square, circular, etc.

[0003] When the existing aeration tank is aerated, the gas entering is likely to form relatively large bubbles, resulting in poor aeration reaction effect and affecting the reaction effect of sewage.

The exhaust mesh cover is rotatably installed outside the L-shaped conduit, and a plurality of stirring rods are fixedly installed on the exhaust mesh cover.

[0013] The gas in the L-shaped conduit is discharged through the exhaust mesh cover, and the gas is dispersed under the action of the exhaust mesh cover. At the same time, the size of the bubbles can be reduced. At the same time, the arrangement of the stirring rods can stir the sewage, so that the air can fully contact the sewage.

[0018] Preferably, an eccentric shaft is fixedly installed at the bottom of the turntable, and the eccentric shaft is slidably connected to the loop-shaped frame.
