Embodiment Construction
[0015] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.
[0016] Reference Figure 1-2 , An aeration device for sewage treatment, comprising a base 8, a plurality of brackets 9 distributed in an annular shape are welded to the lower end of the base 8 to support the installation device, and a chassis 18 is provided above the base 8. A turntable 7 is provided between the chassis 18 and the base 8. The turntable 7 and the base 8 are connected to the chassis 18 in rotation, and a stirring rod 24 is slidably connected to the turntable 7, and a stirring blade 26 is welded to the lower end of the stirring rod 24. The bottom of the sewage tank is stirred to agitate the sewage to make the garbage residue a...

The invention discloses an aeration device for sewage treatment, which comprises a machine base, a plurality of ring-shaped brackets are welded on the lower end of the machine base, and a cabinet is arranged above the machine base, the cabinet and the machine base There is a turntable between them, the turntable is connected with the machine base and the case in rotation, and a stirring rod is slidably connected to the turntable, the lower end of the stirring rod is welded with a stirring blade, and the upper end of the case is fixedly connected with a motor. The output shaft of the motor is fixedly connected with a drive pulley, and the end of the chassis far away from the motor is fixedly connected with a shaft seat, and a support rod is rotatably connected between the shaft seat and the inner side wall of the case, and the support rod is sequentially fixed with sleeves A driven pulley and a crown gear are connected, and the driven pulley and the driving pulley are connected in rotation through a transmission belt. The invention has a novel structure, can well complete the aeration operation in the sewage treatment, and at the same time stirs the sewage pool to fully contact the impurities and the like with the flocculant, thereby improving the treatment efficiency.
Description
Technical field [0001] The invention relates to the technical field of sewage treatment devices, and in particular to an aeration device for sewage treatment. Background technique [0002] Aeration is one of the most important processes in the activated sludge process for sewage biochemical treatment. The submersible aerator drives the impeller to rotate at a high speed. The impeller generates strong centrifugal force. Under the action of the centrifugal force, a negative pressure zone is formed around the impeller. Self-suction is generated, and a large amount of fresh air in the atmosphere is continuously sucked through the suction pipe. At the same time, the impeller sucks sewage into the suction cover. In the suction cover, the sewage and the sucked air collide with each other to form a large number of ultra-fine bubbles passing through the guide groove It is sprayed around, and the sprayed gas-liquid mixed flow produces the effect of stirring and convection. Due to the gene...
