Embodiment 1

[0016] A method for recycling metal scraps during machining, comprising the following steps:

[0017] (1) Firstly, metal scrap is collected through the scrap collection device in conjunction with the structure of the workbench and the use of processing tools;

[0018] (2) Combine the collected metal waste with a hammer crusher and a scissor crusher for crushing, and crush the waste to 15 meshes;

[0019] (3) Soak the crushed metal waste powder in an organic solvent for 60 minutes;

[0020] (4) Dry the metal scrap soaked in organic solvent at a drying temperature of 90°C for 2 hours;

[0021] (5) Screen the dried metal scraps and classify them according to the number of meshes and store them in vacuum for later use.

Embodiment 2

[0023] A method for recycling metal scraps during machining, comprising the following steps:

[0024] (1) Firstly, metal scrap is collected through the scrap collection device in conjunction with the structure of the workbench and the use of processing tools;

[0025] (2) Combine the collected metal waste with a hammer crusher and a scissor crusher for crushing, and crush the waste to 45 meshes;

[0026] (3) Soak the crushed metal waste powder in an organic solvent for 90 minutes;

[0027] (4) Dry the metal scrap soaked in organic solvent at a drying temperature of 110°C for 3 hours;

[0028] (5) Screen the dried metal scraps and classify them according to the number of meshes and store them in vacuum for later use.

Embodiment 3

[0030] A method for recycling metal scraps during machining, comprising the following steps:

[0031] (1) Firstly, metal scrap is collected through the scrap collection device in conjunction with the structure of the workbench and the use of processing tools;

[0032] (2) Combine the collected metal waste with a hammer crusher and a scissor crusher for crushing, and crush the waste to 30 meshes;

[0033] (3) Soak the crushed metal waste powder in an organic solvent for 75 minutes;

[0034] (4) Dry the metal waste after soaking in organic solvent, the drying temperature is 100°C, and the treatment time is 2.5h;

[0035] (5) Screen the dried metal scraps and classify them according to the number of meshes and store them in vacuum for later use.

Abstract

The invention discloses a recovery method of metal waste during machining process. The recovery method comprises the following steps: firstly effectively collecting waste material; then crushing the waste material, soaking the waste material by an organic solvent, drying and then performing classification sieving; and finally performing vacuum storage. According to the recovery method, the recovery cost of the metal waste is effectively reduced, and the classification sieving of the waste material is easy through the processing steps of pretreatment, and thus the environmental pressure and economic loss caused by blind chemical treatment for mixture of the metal waste in the traditional technology are prevented.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a method for recycling metal waste in the machining process. Background technique [0002] With the development of industry and the advancement of science and technology, there are more and more scraps in the machining industry, especially metal scraps such as iron scraps, aluminum scraps, nickel scraps or some alloy scraps in the processing of the steel industry, machinery industry, and electronics industry. , and its output makes people think deeply. If they are not properly disposed of, on the one hand, it will cause great pressure on the environment, on the other hand, it will also waste its own surplus value, and it will also be a great loss to social resources. At present, many treatment methods are not classified and screened, but the waste mixture is directly subjected to complex chemical treatment processes, acid-dissolved, impurity-removed, filtered, precipitated an...
