9. The device for recovering nonferrous metals according to claim 1, characterized in that: The outer wall cleaning mechanism comprises two groups of support columns (31) mounted on both sides of the material guide seat (2); the tops of the support columns (31) are connected to a mounting horizontal plate (32); a plurality of flushing nozzles (33) are arranged on the mounting horizontal plate (32); and the mounting surfaces of the flushing nozzles (33) are inclined structures.

10. A system for recovering nonferrous metals according to any one of claims 1 to 9, characterized in that: The system includes a collection and processing module, a classification and disassembly module, a smelting and refining module, a quality inspection module, a product molding module, a waste treatment module, a logistics and sales module, and an information management module; The collection and processing module is responsible for collecting scrap nonferrous metals and performing preliminary pretreatment, collecting nonferrous metal scraps by setting up recycling points, cooperative recycling stations or directly collecting scraps from production enterprises, manually or mechanically sorting, removing obvious large pieces of non-metallic impurities, using crushers to break large pieces of scrap into small particles, and using cleaning equipment to clean the scraps to remove oil stains, paint, etc.; The classification and disassembly module further classifies and disassembles the non-ferrous metals to separate different metals; The smelting and refining module smelts the classified nonferrous metals to remove impurities and obtain metals with higher purity; The quality inspection module performs component analysis on the smelted and refined metals, uses a spectrometer, chemical analysis and other means to detect the metal composition and purity, and adjusts the smelting and refining process parameters according to the test results to ensure that the metals meet the specified purity and quality standards; The product forming module casts the refined metal into a shape for easy storage, transportation and use; The waste treatment module processes the waste residue and waste liquid generated during the recycling process to ensure that the entire recycling process meets environmental protection requirements and reduces pollution to the environment; The logistics and sales module is responsible for transporting finished metals to the market and selling them to achieve the economic benefits of non-ferrous metal recycling; The information management module includes an information management system for recording and managing data throughout the entire recycling process in order to track and optimize the entire recycling process. Data recording is required, and a computer system is used to record data such as the source of waste materials, processing process, product quality, sales status, etc., and then process monitoring is carried out. Through real-time data monitoring, the smoothness of the production process and the stability of product quality are ensured. Data analysis is carried out regularly to optimize the recycling process and improve efficiency and profit margins.
