Description

Technical Field

[0001] The utility model relates to the technical field of electrolytic aluminum equipment, and more specifically, the utility model relates to a slag cleaning and scraping device for electrolytic aluminum. Background Art

[0002] During the electrolysis process of molten aluminum, after a series of reactions, it needs to be pumped out of the electrolytic cell through a vacuum ladle and then sent to the casting workshop for subsequent processing. In the casting workshop, the molten aluminum will first be sent into a holding furnace for purification and clarification to remove impurities and gases in it, ensuring the purity of the molten aluminum. The purified molten aluminum will be cast into aluminum ingots and then further processed into wire-matched profiles.

[0003] However, during the casting and processing of molten aluminum, residues will inevitably be generated in the furnace. If these residues are not cleaned in time, it will seriously affect the product quality of aluminum ingots and wire-matched profiles, and may even cause production safety accidents. Therefore, residue cleaning is an essential part of the molten aluminum processing process. Traditional residue cleaning methods usually rely on manual operations by workers. Workers need to hold slag scraping tools and reach deep into the furnace to clean out the residues one by one. This method not only has low efficiency, but also the cleaning effect is not satisfactory. Due to the high temperature and harsh environment in the furnace, long-term manual operations will not only make workers extremely tired, but may also cause damage to the physical health of workers. In addition, existing residue cleaning devices also have certain defects. Since the specifications of the furnaces used in the molten aluminum processing process vary, existing devices often cannot adapt to furnaces with different diameters. This results in that in actual operations, different devices may need to be frequently replaced to adapt to different furnaces, greatly increasing the complexity and cost of operations. Summary of the Utility Model
