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

Embodiment 1

[0072] Embodiment 1, rare precious metal turning material cleaning process

[0073]Referring to accompanying drawing, working process of the present invention is:

[0074] A, magnetic separation and impurity removal: take the metal turning material and put it into the magnetic separation device 2 after crushing to remove some magnetic impurities, then put the metal turning material into the operation material basket 100, and each operation material basket 100 is loaded with 10-15 kilograms; In this step, the stepping manipulator 200 is consistent with the stepping conveyor belt, stepping once every 80s on average;

[0075] B. Wind blowing and impurity removal: put the operation material basket 100 carrying the metal turning material on the starting end of the stepping conveyor belt, and when the operation material basket 100 travels to the end of the stepping conveyor belt, the stepping robot hand 200 grasps the operation material basket 100 into the air-blowing cleaning tank...

Embodiment 2

[0089] Embodiment 2, the special device of cleaning process

[0090] Referring to the accompanying drawings, the special device of the present invention includes a magnetic separation device 2, a cleaning and drying assembly, a sand washing and drying assembly, and a receiving device 5 in sequence according to the sequence of flow operation; Miscellaneous wind-blown cleaning tank 11, spray cleaning tank 21 for removing impurities by water washing, at least one set of lye ultrasonic cleaning tank 31, at least one set of bubbling cleaning tank 41, using gravity for natural dehydration and drying Drying tank 3 and the wind-cutting drying tank 51 that utilizes wind blowing to dry; the sand washing and drying assembly is arranged at the lower station of the cleaning and drying assembly, which successively includes a three-dimensional rolling sand washing device 60, a separation sand sand material separation device 70, at least one group of bubbling cleaning tanks 41, wind-cutting d...

Abstract

The invention discloses a rare / precious metal turning material cleaning process. The process comprises the following core operating steps: (A) carrying out impurity removal by magnetic separation; (B) carrying out impurity removal by blowing; (C) carrying out coarse wash by spraying; (D-1) carrying out first-time ultrasonic washing by alkali liquor; (D-2) carrying out second-time ultrasonic washing by alkali liquor; (E) carrying out blistering rinsing; (F) carrying out gravitational drying; (G) carrying out wind-shearing drying; (H) carrying out sand washing operation; (I) carrying out sand separation; (J) carrying out blistering rinsing; (K) carrying out gravitational drying; (L) carrying out wind-shearing drying; and (M) baking and conveying to a material receiving device by a stepping conveyer belt after the baking is completed, thereby completing a whole operation flow. According to the rare / precious metal turning material cleaning process, a 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 method, in particular to a cleaning process for metal turning material assembly line operations. 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...
