Description

Technical Field

[0001] The utility model relates to the technical field of electrolytic aluminum processing, in particular to an aluminum ash processing device for electrolytic aluminum processing. Background Art

[0002] At present, electrolytic aluminum processing is the process of obtaining aluminum through electrolysis. Modern electrolytic aluminum industrial production adopts cryolite-alumina molten salt electrolysis. Molten cryolite is the solvent, alumina is the solute, carbonite is the anode, and aluminum liquid is the cathode. After a strong direct current is passed through, an electrochemical reaction is carried out at the two electrodes in the electrolytic cell at 950℃-970℃.

[0003] During the electrolytic aluminum processing process, the aluminum liquid is sucked into the aluminum ladle through the negative pressure formed by compressed air, and then sent to the foundry by the ladle transport vehicle to be cast into ordinary aluminum ingots for remelting and other products. The aluminum liquid needs to be purified and smelted in a mixing furnace before casting. In order to absorb harmful inclusions in the aluminum liquid, reduce the viscosity of the slag on the surface of the aluminum liquid, and prevent the oxidation of the aluminum liquid, some additives are added during the aluminum liquid smelting process, resulting in a certain amount of slag on the surface of the aluminum liquid. This slag needs to be manually or mechanically scraped out of the mixing furnace before casting. The scraped slag is in the form of loose ash, so it is called aluminum ash.

[0004] The aluminum ash produced is convenient for secondary utilization and will be physically separated by a ball mill. However, when using a ball mill, not only will the large volume of aluminum ash affect the grinding efficiency of the ball mill, but a large amount of dust will be generated during discharge and screening, affecting the working environment. Therefore, a new technical solution needs to be designed to solve this problem. Utility Model Content
