Nepenthes type aluminum scrap recycling treatment process

Abstract

The invention discloses a nepenthes type aluminum scrap recycling treatment process, and belongs to the field of metal waste recovery. The nepenthes type aluminum scrap recycling treatment process hasthe beneficial effects that the two steps of screening and impurity removal, and magnetic separation and iron removal are combined in one step through the use of a nepenthes type screening barrel, sothat the aluminum scrap recovery process is simplified, and the time of the aluminum scrap recycling treatment is saved to a great extent, and the efficiency of the aluminum scrap recycling treatmentis remarkably improved; meanwhile, nepenthes type special-shaped sleeve pipes in screening holes are used so as to enable the probability that aluminum scraps are gotten stuck in the screening holesto be reduced, and the service life of a screen is prolonged; and meanwhile, nano-scale micropores of the nepenthes type special-shaped sleeve pipes and lubricating oil inside the nepenthes type special-shaped sleeve pipes are used, so that the aluminum scraps gotten stuck in the screening holes are just like insects preyed by nepenthes and are very difficult to stay in the screening holes; and even if the aluminum scraps are gotten stuck, when the aluminum scraps are taken out, the screen can be effectively protected due to the reduction of the friction, so that the probability that the screen is damaged by the aluminum scraps is reduced, and the cost investment of the aluminum scrap treatment is reduced.

Description

technical field [0001] The invention relates to the field of recycling metal scraps, and more specifically, relates to a recycling process of nepenthes type aluminum chips. Background technique [0002] A large amount of aluminum chips will be generated when the machine tool is in operation. The current way to deal with aluminum chips is that each machine tool is equipped with an independent aluminum chip collection box, and the aluminum chip collection box needs to be replaced every 4 hours. The chips are transported to the aluminum chip processing system for unified treatment, and the aluminum chip collection box needs to be manually dragged out every month to clean the sediment inside. When aluminum castings are cut, chips account for about 20% of the weight of the castings, up to about 30%. At present, the price of aluminum in the market is about 15,000 yuan / ton, so recycling the aluminum chips in the machining process of the piston series products can reduce the produc...

Problems solved by technology

[0003] Aluminum chip recycling generally includes the steps of collecting aluminum chips in the workshop, preheating and baking, screening and removing impurities, magnetic separation and iron removal, and ingot casting. However, due to the uncertain size and shape of aluminum chips, and the edges of aluminum chips are usually sharp, As a result, during the screening process, aluminum chips are often stuck in the sieve holes of the screen, unable to go up and down, which will seriously affect the screening effect of the screen, thereby affecting the working efficiency of the entire aluminum chip recycling process. Forcibly removing the aluminum chips stuck on the screen is easy to damage the screen, resulting in a reduction in the service life of the screen and increasing the cost of recycling aluminum chips
