A special device for cleaning rare and precious metal turning material

Abstract

The invention discloses a special device for cleaning a rare / precious metal turning material. The special device comprises an operating material basket which is used for containing the metal turning material, wherein the operating material basket sequentially comprises a magnetic separation apparatus, a cleaning and drying assembly, a sand washing and drying assembly and a material receiving device according to an assembly-line operation sequence; the cleaning and drying assembly sequentially comprises a blowing-washing tank platform which is used for preliminarily removing impurities by wind power, a sprinkling-washing tank platform which is used for removing impurities by water washing, at least one group of alkali-liquor ultrasonic washing tank platform, at least one group of blistering-washing tank platform, a gravitational drying tank platform which is used for naturally dehydrating and drying by using gravity, and a wind-shearing drying tank platform which is used for drying through blowing according to the assembly-line operation sequence; the sand washing and drying assembly is arranged at a next station of the cleaning and drying assembly. According to the special device for cleaning the rare / precious metal turning material, the turning material can be subjected to cleaning treatment and can be subjected to original-value smelting (high-proportion value reduction can be caused during ordinary treatment), so that the cost of rare / precious metal material smelting is greatly reduced, and a large number of resources are saved; meanwhile, the pollution caused by smelting pure rare / precious metals by using raw ores is reduced, and the environment is protected.

Description

technical field [0001] The invention relates to an industrial cleaning device, in particular to a system device for pipelined cleaning of metal turning materials. Background technique [0002] During the machining process of metal, a large amount of waste will be generated, which will be piled up in the form of strips and coils. After reaching a certain scale, they will be treated centrally, and some of them will be directly discarded as industrial waste. With the advancement of recycling technology for precious metal turning materials, most manufacturers will sell metal processing waste at a suitable price, and enter professional metal turning material processing enterprises through market circulation. [0003] First of all, strip-like metal turning materials from metal turning workshops often contain a lot of impurities, including dust, soil and rocks, plastic strip bags, cigarette butts, wood chips, food residues, etc. In order to remove or reduce these impurities, a The...

AI Technical Summary

Problems solved by technology

A large amount of turning material will be produced during lathe processing. At present, the turning material is devalued and smelted after simple recycling (metal materials containing vanadium, niobium, tungsten, cobalt and nickel are used to smelt common steel types), and the rare and precious metals in it have not been effectively utilized. great waste of resources
