A kind of cutting fluid purification method

Abstract

The invention relates to a cutting fluid purification method which comprises a bottom plate, a shell frame, a filtering device and a demagnetizing device. The shell frame is mounted at the upper end of the bottom plate, the section of the shell frame is of a U-shaped structure, the filtering device is mounted at the upper end of the interior of the shell frame, and the demagnetizing device is arranged below the filtering device and is mounted at the lower end of the interior of the shell frame. According to the present invention, the problems that when an existing device is used for filteringthe cutting fluid, the filtering effect is poor; and the filtering is incomplete; generally, a large amount of metal waste is mixed in the filtered filtrate, so that the subsequent treatment of the filtrate is influenced; meanwhile, the filter residues cannot be cleaned rapidly, so that the filtering efficiency is influenced; moreover, when the magnetic metals in waste liquid are removed, the removed metal impurities cannot be cleaned and collected effectively, so that the metal impurities cause the secondary pollution to the cutting fluid, and the use effect of the cutting fluid is influenced, etc., can be solved.

Description

technical field [0001] The invention relates to the technical field of cutting fluid purification, in particular to a cutting fluid purification method. Background technique [0002] Cutting fluid is an industrial liquid used in metal cutting and grinding to cool and lubricate cutting tools and workpieces. Cooling performance, lubricating performance, anti-rust performance, degreasing and cleaning function, anti-corrosion function, easy to dilute. In order to avoid the waste of cutting fluid, the cutting fluid is usually recycled. However, the recovered cutting fluid usually contains a large amount of impurities such as metal impurities and dirty oil, so the cutting fluid needs to be purified. [0003] At present, the existing cutting fluid usually has the following defects in the purification process: 1. When the cutting fluid is filtered, the filtering effect is poor and the filtration is incomplete. The filtered filtrate is usually mixed with a large amount of metal wast...

AI Technical Summary

Problems solved by technology

[0005] The present invention can solve the problem that the existing equipment has poor filtering effect and incomplete filtering when filtering the cutting fluid, and the filtered filtrate is usually mixed with a large amount of metal waste, which affects the subsequent treatment of the filtrate, and at the same time cannot quickly remove the filter residue. Cleaning will affect the filtration efficiency, and when removing the magnetic metal inside the waste liquid, the removed metal impurities cannot be effectively cleaned and collected, resulting in secondary pollution of the cutting fluid by the metal impurities and affecting the use of the cutting fluid Effects and other problems
