Description

Technical Field

[0001] The invention relates to the technical field of aluminum alloy processing, and in particular to a device for recycling and processing aluminum alloy profile processing waste. Background Art

[0002] Aluminum alloy profiles are the most widely used nonferrous metal structural materials in industry, and have been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding, construction, decoration, and chemical industries. With the rapid development of science and technology and industrial economy in recent years, the demand for aluminum alloy profiles has increased day by day. However, aluminum alloy profiles are not specially customized, and a large amount of scraps will inevitably be generated during use. The installed aluminum alloy profile components will also have a certain damage rate, and the damaged profiles replaced are countless. If they are not recycled, it will cause a lot of waste of resources.

[0003] When aluminum alloy profiles are used, they are usually matched with other alloy metal components as connectors, which mainly include screws and bolts. These connectors are often made of iron. It is impossible for the staff to dismantle these connectors one by one and then melt the waste. They are often directly melted at high temperature, which greatly increases the iron content in the recycled aluminum alloy parts. When there is too much iron, brittle metal crystals will form in the aluminum, thereby reducing its mechanical properties and weakening its corrosion resistance. As a result, the quality of aluminum alloy profile recycling and recasting is generally poor. In the process of transporting and placing waste profiles, a lot of sand and impurities will adhere to the surface of the aluminum alloy profile waste. The aluminum alloy waste after melting and recycling will have problems with many impurities and poor quality. Summary of the invention
