[0001] The utility model relates to the technical field of cleaning devices, in particular to a cleaning device for an oil-water separation tank with air flotation for oil removal. Background Art

[0002] The cleaning device for an oil-water separation tank with air flotation for oil removal is usually installed inside the tank body of the oil-water separation tank to effectively clean and process floating oil and floating scum. Nowadays, common cleaning devices usually install a support plate at the opening on the top of the tank body, and a motor is arranged on the support plate. The motor drives a rotating shaft to drive a scraper welded on the outer wall of the rotating shaft, so as to complete the sorting of the floating scum and grease on the surface of the wastewater, making it located at the side wall of the scraper, and then the cleaning is completed manually.

[0003] However, for the common cleaning device for an oil-water separation tank with air flotation for oil removal, since the scraper accumulates the floating scum on the side wall and it also floats on the water surface, it still requires the staff to clean the floating scum on the water surface, resulting in a reduction in the cleaning effect of the scraper. In view of this, we propose a cleaning device for an oil-water separation tank with air flotation for oil removal. Summary of the Utility Model

[0015] By starting the cylinder, the cleaning assembly can be driven to lift as a whole, which is beneficial to adjusting the height of the cleaning assembly according to the water level change. When there is a water level difference, it can avoid the situation that it is difficult for the cleaning assembly to clean the scum and grease floating on the water surface, reducing the cleaning effect. At the same time, by starting the motor, the telescopic assembly can be driven to drive the gear to rotate, so that the gear cooperates with the toothed ring to drive the sewage extraction pump to rotate.
