Description

Technical Field

[0001] The utility model relates to the technical field of cleaning devices, in particular to an air flotation machine cleaning device. Background Art

[0002] Air flotation machine is a kind of water treatment equipment. Its working principle is to generate a large number of fine bubbles in the water through the dissolved air system, so that the air is attached to the suspended particles in the form of highly dispersed tiny bubbles, resulting in a state where the density is less than that of water. The buoyancy principle is then used to make these particles float on the water surface, thus achieving solid-liquid separation. This equipment is widely used in the treatment of various industrial and municipal sewage, including the removal of suspended solids, grease and various colloids.

[0003] There are many types of air flotation machines, including super-efficient shallow air flotation machines, vortex air flotation machines and horizontal air flotation machines. They have their own characteristics, but their common goal is to improve water quality and achieve effective solid-liquid separation. The main advantages of air flotation machines are good solid-liquid separation effect, low investment, small footprint, high degree of automation, and easy operation and management.

[0004] In order to remove the sludge, impurities and other pollutants accumulated inside the equipment to ensure its normal operation and maintain good treatment effects, the flotation machine needs to be cleaned regularly;

[0005] After searching, such as Chinese patent: CN219597590U, a flotation machine cleaning device includes a shell, both sides of the top of the shell are fixedly connected with a connecting frame, the top of the inner cavity of the connecting frame is fixedly connected with an electric push rod, and the output end of the electric push rod is fixedly connected with a first scraper. Through the cooperation of the electric push rod and the first scraper, impurities on the inner walls of both sides of the shell are scraped off, and through the cooperation of the motor, the threaded rod, the movable frame and the second scraper, impurities adhering to the front and back of the inner cavity of the shell are scraped off. Through the cooperation of the water tank, the transmission pipe, the nozzle and the first valve, the water in the inner cavity of the water tank is sprayed on the inner wall of the shell, and then the water carries the impurities and slides off, completing the cleaning of the inner wall of the shell, solving the problem that some impurities floating on the water surface of the flotation machine will adhere to the inner shell wall of the flotation machine, which is not convenient for salvaging and removing, and then affecting the discharge of impurities, thereby causing incomplete impurity removal.

[0006] Although the existing flotation machine cleaning device can clean the inner wall of the shell through the cooperation of the water tank and the scraper, the scraper cannot clean the bottom of the inner wall of the shell, resulting in incomplete cleaning. Utility Model Content
