Description

Technical Field

[0001] The invention relates to the technical field of scrap iron recycling equipment, and in particular discloses a scrap iron recycling device for machining. Background Art

[0002] Machining mainly involves cutting and grinding workpieces with the help of lathes, milling machines, drilling machines and other metal processing equipment to produce metal parts of the required shape and size. During the machining process, metal materials will produce scraps when they are cut and ground, and the scraps are iron or metal scraps. In order to optimize production costs and improve resource utilization, most manufacturers need to recycle scrap iron generated during machining. This can not only reduce production costs and energy consumption, but also reduce environmental pollution and improve the cleanliness of the machining area.

[0003] Most of the scrap iron generated during the machining process is directly scattered in the working area. After the machining operation is completed, the on-site operators need to collect the scrap iron in the working area through cleaning and collection equipment. At present, most operators pile the collected scrap iron into storage boxes. Since the scrap iron is easily contaminated with sewage and moisture in the machining operation area, the scrap iron is humid and the water content is too high, causing the scrap iron to oxidize and produce rust. If the proportion of rust in the scrap iron is high, the recycling rate of the scrap iron will be reduced, which will greatly affect the purity of the metal products and lead to a decline in quality. At the same time, it is necessary to add additional reducing agents for removing rust during the recycling process, which further increases energy consumption and production costs, and limits the market competitiveness of the product. Summary of the invention
