Aeration tank surface scum cleaning device for sewage treatment

Abstract

The invention relates to the technical field of sewage treatment, and discloses an aeration tank surface scum cleaning device for sewage treatment. The cleaning device comprises a water tank, an air cylinder is fixedly connected to the inner bottom wall of the water tank, a fixing disc is fixedly connected to the top of the air cylinder, a sleeve is connected to the outer portion of the fixing disc in a sleeving mode, and a motor is rotationally connected to the top of the sleeve. Rotating pipes are fixedly connected to the two sides of the sleeve, cavities and inner cavities are formed in the rotating pipes, first sliding rods are fixedly connected to the interiors of the cavities, floating plates are connected to the exteriors of the two first sliding rods in a sleeving mode, and hard pipes are fixedly connected to the bottoms of the two floating plates. After the position of the rotating pipes is adjusted, the floating plates float on the water surface, the hard pipes are always located below the water level under the action of the floating plates, the effect of finely adjusting the position of the hard pipes is achieved, and the situation that the hard pipes cannot suck away scum when sucking sewage due to the fact that the hard pipes are located at the too deep position above or below the water level is prevented.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a device for cleaning scum on the surface of an aeration tank for sewage treatment. Background technique [0002] Sewage refers to the polluted discharge water from life and production. It can also be understood as water that has lost its original function. With the improvement of people's awareness of environmental protection, sewage treatment has attracted more and more attention. , Aeration treatment is an important link, after aeration, the oxygen in the air is transferred to the mixed liquid and used by microorganisms. [0003] During the process of aeration treatment, scum will be continuously produced on the surface of the sewage. If it cannot be treated in time, the scum will be merged into the sewage again, reducing the aeration effect. The current treatment method is manual salvage, which is time-consuming and laborious, and workers It is dangerous to work nex...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a device for cleaning the scum on the surface of the aeration tank for sewage treatment, which is equipped with automatic cleaning of the scum generated on the surface of the sewage during aeration and automatic cleaning of the suction pipe tip according to the change of the liquid level. The advantage of fine-tuning solves the problem that the existing method of cleaning the scum generated on the surface of the sewage during aeration is through manual salvage, which is time-consuming and laborious, and the workers work beside the aeration tank for a long time during salvage, which is relatively dangerous.
