Description

Technical Field

[0001] The invention belongs to the technical field of aluminum rod production technology, and specifically relates to a raw material melting and impurity removal device for aluminum rod production. Background Art

[0002] Aluminum rod is a kind of aluminum product. The casting of aluminum rod includes melting, purification, impurity removal, degassing, slag removal and casting process. Aluminum rod is the raw material for many aluminum alloys and aluminum products. As a common metal material, aluminum rod has excellent electrical conductivity, thermal conductivity and good processing performance. It is widely used in many fields such as machinery manufacturing, electronic equipment, and architectural decoration to meet the needs of all walks of life. Aluminum rod is widely used in the field of machinery manufacturing. The aluminum products made of it have the characteristics of light weight, high strength and good corrosion resistance.

[0003] Part of the raw materials for aluminum rod production are recycled aluminum products. After high-temperature melting, there will be many impurities on their surface. Therefore, when producing aluminum rods, it is necessary to effectively clean the impurities on the surface of the molten aluminum water. In the utility model patent with 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, and 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 a primary degassing chamber and a secondary degassing chamber, the aluminum melt is degassed twice online, which effectively ensures the degassing effect, improves the purification efficiency, and effectively ensures 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 liquid. The suspended matter on the surface of the aluminum liquid will remain on the filter screen in the filter chamber and is difficult to clean.

[0005] It is difficult to clean the suspended matter on the surface of the aluminum liquid when the existing online degassing device for aluminum melt is 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, which is difficult to clean.
