Solid waste is inevitably generated in the process of industrial production, and can be divided into hazardous solid waste and general solid waste, depending on the degree of danger under China's environmental management requirements.
Oil-impregnated metal chips are metal chips that are contaminated with oil/water, hydrocarbon/water mixtures, degreasers, and waste mineral oil generated during production processes in the metalworking industry. The metal chips themselves are not harmful, but oil-filled metal chips are. According to the ``General Rules for Identification of Hazardous Waste'', ``When hazardous waste that has toxic and/or infectious hazards is mixed with other substances, the toxicity spreads to other substances. The mixed solid waste becomes hazardous waste.''
Currently, according to the waste production link's judgment, the metal chips generated during cutting are generally in the form of flakes or shavings, with a relatively small specific surface area, and are free from mineral oil, oil/water, hydrocarbon/ Most of the water mixture and degreasing agent can be removed by mechanical degreasing techniques, and the metal chips generated by grinding and honing are generally in the form of powder or mud, with a large specific surface area, high oil content, and simple It cannot be removed by mechanical degreasing techniques. Therefore, depending on a company's production process, it may be necessary to collect metal chips containing oil and store them separately. Therefore, there is an urgent need to find a simpler and more efficient method to quickly process oil-bearing metal chips in order to achieve effective control of oil-bearing metal chips.

A method for treating oil-impregnated metal chips using the apparatus according to any one of claims 1 to 5, comprising:
Step S1: sieving and classifying;
The oil-impregnated metal chips are placed in the first separating tube (1) of the sieving device, and the first motor (41) is started to rotate the first stirring rod (11) to remove the powdery and muddy oil-impregnated metal chips. The oil-impregnated metal chips in the form of flakes and shavings are held inside the first separating cylinder (1) by leaking from the bottom and side wall screen of the first separating cylinder (1) and falling into the material guide groove (3) . Contains grain-like and cut-knot-like
The oil-impregnated metal chips are called first oil-impregnated metal chips, and the powdered and muddy oil-impregnated metal chips are called second oil-impregnated metal chips.
It is called oil metal chip.
the second oil-impregnated metal chip is discharged, pressed into a cake shape, and stored;
Step S2, a step of degreasing;
The first oil-impregnated metal chips are held in the first separation cylinder (1) of the sieving device, and at the same time the second separation cylinder (
2) by adding water and a degreasing agent so that the weight ratio of the first oil-impregnated metal chip, water and degreasing agent is 1:3:0.
.. 5 to 2, the water and degreaser are passed through the screen of the first separation cylinder (1) to submerge the first oil-impregnated metal chips, and the first stirring rod (11) and the The second stirring rod (7) in the two separation cylinders (2) is simultaneously rotated in opposite directions to perform rotary degreasing treatment, and the treatment time is 15 minutes.
~20min,
Step S3: collecting and detecting;
In step S2, the degreased first oil-impregnated metal chips are collected and dried, the content of petroleum hydrocarbons in the first metal chips is detected, and the content of petroleum hydrocarbons in the first metal chips is ≧3%. If the content of petroleum hydrocarbons in the first metal chip is <3%, the process returns to step S2 to perform a degreasing process, and the process is completed and stored.
