Embodiment 1
[0051] see figure 1 , a kind of nepenthes type aluminum scrap recycling process, comprises the following steps:
[0052] S1. Collect aluminum shavings produced after aluminum processing in the workshop;
[0053] S2. Preheating and baking. Put the aluminum chips recovered in S1 on the steel plate to heat and bake to remove the oil and moisture on the aluminum chips. The baking temperature is controlled between 280°C. If the temperature is too high, not only the heat loss is large, Moreover, it will cause strong oxidation of aluminum chips, and too low temperature will lead to prolonged baking time, which will affect the efficiency of recycling aluminum chips;
[0054] S3. Screening to remove impurities and magnetic separation to remove iron. Pour the cooled aluminum scraps into a pitcher-type sieving bucket for screening to remove impurities such as sediment and oxidized powder, so the iron scraps can be removed. ; The specific operation is:
[0055] Step 1: Pour an appropri...

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...
