Description

Technical Field

[0001] The present invention relates to the technical field of nonferrous metal recycling, and in particular to a park-based waste nonferrous metal recycling device and method. Background Art

[0002] Nonferrous metals, also known as non-ferrous metals in a narrow sense, refer to all metals other than iron (and sometimes manganese and chromium) and iron-based alloys. They can be categorized as heavy metals, light metals, precious metals, and rare metals. In a broader sense, nonferrous metals also include nonferrous alloys, which are alloys composed of one or more other elements in a nonferrous metal matrix. Nonferrous metals are fundamental materials for national economic development. Most industries, including aviation, aerospace, automotive, machinery manufacturing, electricity, communications, construction, and home appliances, rely on nonferrous metals for production. With the rapid advancement of modern industry, agriculture, and science and technology, nonferrous metals are playing an increasingly important role in human development. They are not only important strategic materials and means of production worldwide, but also essential consumer goods. The production of nonferrous metals in nonferrous metal industrial parks generates a certain amount of waste nonferrous metals, which require recycling equipment. During the recycling process, pre-treated metal materials are added to the smelting furnace for smelting.

[0003] Waste non-ferrous metals are often mixed together in various forms, including blocks, flakes, powders, etc., and may be mixed with other impurities. The smelting furnace can provide a high enough temperature to transform non-ferrous metals from solid to liquid. When the waste non-ferrous metals are placed in the smelting furnace and heated to the corresponding temperature, the non-ferrous metals will melt, and most non-metallic impurities will undergo decomposition, oxidation and other reactions at high temperatures because their melting points are much higher than those of non-ferrous metals or they will undergo other reactions such as decomposition and oxidation at high temperatures, thereby achieving preliminary separation from non-ferrous metals. This is an important part of the non-ferrous metal recycling process.

[0004] However, existing waste non-ferrous metal recycling smelting furnaces still have certain drawbacks. When melting non-ferrous metals, these furnaces generate flue gas and excess heat. These furnaces are unable to recycle the excess heat and purify the flue gas, resulting in a waste of resources. Direct emission of the generated flue gas can also cause environmental damage. Therefore, it is necessary to propose a park-based waste non-ferrous metal recycling device and method to address these issues. Summary of the Invention
