Technical Field

[0001] The utility model relates to the technical field of ultrasonic treatment of waste aluminum alloy, in particular to an ultrasonic degreasing device for waste aluminum alloy scraps. Background Technique

[0002] Aluminum alloy is an alloy with aluminum as the base and a certain amount of other alloying elements added. It is one of the light metal materials, having good casting performance and plastic processing performance, good electrical and thermal conductivity, good corrosion resistance and weldability, and is widely used in aerospace, aviation, transportation, construction and electromechanics. A large amount of oil stains adhere to the surface of waste aluminum alloy scraps, and degreasing treatment is required when recycling waste aluminum alloy.

[0003] The existing degreasing methods are mainly mechanical stirring cleaning, high-pressure water flow cleaning and laser rust removal. However, the above methods all have defects in different aspects. For example, in mechanical stirring cleaning, a large amount of cleaning agent needs to be used for soaking treatment, which will cause corrosion or oxidation of the aluminum alloy surface; high-pressure water flow cleaning can only treat a small amount of waste materials at a time, cannot handle a large amount of waste materials, and the cleaned parts are mostly large waste materials, and complex waste materials cannot be cleaned; laser rust removal has a high cost and the cleaning effect is not ideal.

[0004] Furthermore, the existing cleaning methods are difficult to meet the processing requirements of a large amount of waste aluminum alloy scraps, and the cleaning effect is not good. Therefore, there is an urgent need for an efficient, environmentally friendly and low-cost cleaning device to process waste aluminum alloy scraps. Content of the Utility Model
