Description

Technical Field

[0001] This utility model relates to the field of electrolytic aluminum and related equipment, and in particular to a flotation machine for flotation of carbon slag in aluminum electrolysis. Background Technology

[0002] A large amount of anode carbon slag is generated during aluminum electrolysis. This is mainly because some anode carbon blocks do not participate in the electrochemical reaction and are mixed into the electrolyte to form carbon slag. Another reason is that when a new electrolytic cell is started up using coke granule roasting, the coke granules used all enter the electrolyte as carbon slag, eventually forming a large amount of carbon slag. Carbon slag is very harmful to electrolytic production. At the same time, in order to recover the carbon resources in the carbon slag, multiple processing steps are required for the carbon slag, and a flotation machine is needed for the carbon slag flotation.

[0003] The prior art can be referenced to the Chinese authorized utility model patent with publication number CN220071998U, which is specifically a flotation machine applied to the flotation of carbon slag in aluminum electrolysis. It includes a flotation box, with discharge ports at both ends of the upper surface of the flotation box. A guide plate is welded to the bottom of the outer wall of the discharge port. A first motor is installed on both sides of the upper surface of the flotation box. The adjustment component includes a hoisting frame and an electric telescopic rod. Electric telescopic rods are installed on both sides of the top of the hoisting frame. A first U-shaped frame and a second U-shaped frame are welded to the bottom sides of the moving plate, respectively. The cleaning component includes a tank and a water pump. A water pump is installed at the center of the top of the tank.

[0004] The aforementioned prior art has the following shortcomings in actual implementation: it cannot clean floating objects on the scraper, and the scraper will bring the floating objects back into the water when it re-enters the water. Utility Model Content

[0033] The present invention provides a technical solution in which, during use, ground carbon slag is fed into the housing 1, flotation reagent is added, and then the liquid inside the housing is stirred using a stirring unit. When skimming is required, the moving drive assembly is activated, which drives the scraper 5 to move, scraping off the floating debris. After the scraper 5 moves out of the housing 1 and into front of the cleaning plate 8, the electric telescopic rod 7 is activated, which drives the cleaning plate 8 to move upward, and the cleaning plate 8 moves downward, thus cleaning the floating debris on the surface of the scraper 5.

[0042] Workflow: The ground carbon slag is fed into the tank 1, and flotation reagents are added. The liquid inside the tank is then stirred using a stirring unit. When skimming is required, the moving drive assembly is activated, which moves the scraper 5 to scrape off the floating debris. Once the scraper 5 has moved out of the tank 1 and is in front of the cleaning plate 8, the electric telescopic rod 7 is activated, which moves the cleaning plate 8 upward. The cleaning plate 8 then moves downward to clean the floating debris on the surface of the scraper 5.

[0043] The second motor 4 drives the first synchronous pulley 15 to rotate, and the synchronous belt 17 drives the second synchronous pulley 16 to rotate. The second synchronous pulley 16 drives the lead screw 12 to rotate, and the lead screw 12 drives the scraper 5 to move. The electric telescopic rod drives the connecting block 13 to move up and down, and the connecting block 13 drives the scraper 5 to move up and down.
