[0002] Aluminum bar is a type of aluminum product. Its production process includes melting, purification, impurity removal, degassing, slag removal, and casting. Aluminum bar is the raw material for many aluminum alloys and aluminum products. As a common metal material, aluminum bar has excellent electrical and thermal conductivity and good processing properties. It is widely used in machinery manufacturing, electronic equipment, architectural decoration, and other fields, meeting the needs of various industries. Aluminum bar is widely used in machinery manufacturing, and aluminum products made from it are characterized by light weight, high strength, and excellent corrosion resistance.

[0003] Part of the raw materials for aluminum rod production is recycled aluminum products. After being melted at high temperature, there will be a lot of impurities on its surface. Therefore, during the production of aluminum rods, it is necessary to effectively clean the impurities on the surface of the molten aluminum liquid. In the utility model patent with the authorization announcement number CN221480026U, an impurity removal device for melting raw materials for aluminum rod production was invented. However, during extraction, the suspended matter on the surface of the aluminum liquid is difficult to clean. At the same time, the process of extracting the aluminum liquid is too cumbersome and the amount of extracted aluminum liquid is too small.

[0004] In the utility model patent with authorization announcement number CN217651293U, an online degassing device for aluminum melt was invented. By setting up a primary degassing chamber and a secondary degassing chamber, the aluminum melt is degassed twice online, effectively ensuring the degassing effect, improving the purification efficiency, and effectively ensuring the melt quality of the aluminum melt, thereby improving the product quality of aluminum products; however, it is also difficult to remove suspended matter on the surface of the aluminum melt. The suspended matter on the surface of the aluminum melt will remain on the filter screen in the filter chamber and is difficult to clean.

[0005] Existing online degassing devices for molten aluminum are difficult to clean suspended matter on the surface of the aluminum liquid when in use. For example, the above-mentioned patent can fully degas the aluminum melt and improve the product quality of aluminum products. However, the suspended matter on the surface of the aluminum liquid will flow with the aluminum liquid and be adsorbed on the inner wall of the device, causing the inner wall of the device to be filled with suspended matter, making it difficult to clean the suspended matter.
