Description

Technical Field

[0001] The utility model relates to the technical field of sedimentation tanks, in particular to an air flotation sedimentation tank. Background Art

[0002] A flotation sedimentation tank refers to a tank that mainly uses a large number of microbubbles to capture and adsorb fine particles and sticky substances to make them float, thereby achieving the effect of solid-liquid separation. The principle is to form highly dispersed tiny bubbles in the water, which adhere to the hydrophobic solid or liquid particles in the wastewater to form a water-air-particle three-phase mixed system. After the particles adhere to the bubbles, they form flocs with an apparent density less than that of water and float to the water surface, forming a scum layer that is scraped off, thereby achieving the solid-liquid or liquid-liquid separation process.

[0003] For example, the utility model with application number CN201922352082.7 belongs to a high-density flotation sedimentation tank. The utility model overcomes the shortcomings of existing sedimentation tanks and has the advantages of simple structure, high chemical utilization efficiency, good water treatment effect, easy use and good effect. However, most of the existing flotation sedimentation tanks do not have the function of automatic cleaning and decontamination, and require staff to go down into the tank and use tools to perform manual cleaning and decontamination operations. This manual cleaning and decontamination method has a cumbersome operation process, a large workload, high labor intensity and low work efficiency. Utility Model Content

In the present embodiment, the driving member can adopt a driving motor, so that the driving end of the driving motor is connected to the driving gear, and the driven gear is fixedly installed on the rotating shaft. Through the meshing effect of the driving gear and the driven gear, the driving rotation effect of the rotating shaft can be achieved, thereby driving the rotating disk 16 to rotate; an air supply pipe 18 is coaxially installed on the side of the rotating disk 16, one end of the air supply pipe 18 is connected to the external air source, and the other end of the air supply pipe 18 is connected to the air flotation tube 17.

[0022] Working principle:

[0023] When in use, the wastewater is first transported to the pool body 1, and then the gas is transported to the flotation tube 17 through the air pipe 18 for flotation treatment in the pool body 1, so that the gas floats with the scum. In addition, the rotating disk 16 can be driven by a driving motor to rotate, and then the flotation tube 17 can be driven to rotate in the pool body 1, so that a more uniform flotation treatment can be performed in the pool body 1. Then, the screw rod 2 is controlled to rotate under the drive of the motor to drive the screw rod slider 3 to move along the axial direction of the screw rod 2, and at the same time, the lifting electric telescopic rod 4 is controlled to extend, so that the cleaning filter frame 8 moves downward in the pool body 1, so that the cleaning filter frame 8 can be used to pick up scum at different positions inside the pool body 1, and then the driving end of the rotating motor 6 is controlled to drive the connecting shaft 7 to rotate, and then drive the cleaning filter frame 8 to rotate, so that the side of the cleaning filter frame 8 with scum is lifted, and then the lifting electric telescopic rod 4 is controlled to retract to drive the cleaning filter frame 8 to move upward, so that the scraper 10 can contact the surface of the cleaning filter frame 8, so that the cleaning electric telescopic rod 9 can be controlled to operate to drive the scraper 10 to move on the surface of the cleaning filter frame 8, and then the scraper 10 can push the scum on the surface of the cleaning filter frame 8 to achieve the cleaning effect of the surface of the cleaning filter frame 8 for subsequent continued use.
