Abstract

The invention discloses an aluminum scrap regeneration smelting device. According to the aluminum scrap regeneration smelting device, two impellers are applied into a stirring device inside a molten aluminum holding furnace, and air supply holes are formed between the two impellers; when the upper impeller and the lower impeller rotate in the same direction, negative pressure is generated betweenthe two impellers, and gas is promoted to be blended in molten aluminum; and when the two impellers rotate reversely, bubbles are dispersed into the whole molten aluminum better. Further, the size anddispersion degree of the bubbles in the molten aluminum can be adjusted by regulating the rotating speed of a motor and the reverse rotating time of the two impellers, and accordingly, impurity elements in the molten aluminum can be better removed.

Description

technical field [0001] The invention relates to the field of recycling and reprocessing of environmental protection waste, in particular to the technical field of recycled smelting of waste aluminum. Background technique [0002] Aluminum and aluminum alloys have low density, high specific strength, second only to silver and copper in electrical conductivity and heat, and have good processability, beautiful surface gloss, and many special properties such as surface coating. It is widely used in construction, transportation, national defense, packaging and other industries and fields of daily life. my country is a big producer and consumer of aluminum products. However, my country's bauxite resources are very scarce, and the current mining life of bauxite is less than 30 years. Therefore, the ever-expanding market demand and relatively poor aluminum ore resources have become the bottleneck of the future development of my country's aluminum industry. This contradiction has pr...
