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...

Embodiment Construction

[0035] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0036] Such as Figure 1 to Figure 6 Shown, a kind of cutting fluid purification method comprises the following steps:

[0037] S1. Static precipitation: put the recovered cutting fluid into the collection bucket for static precipitation;

[0038] S2. Degreasing the upper layer: Manually remove impurities such as dirty oil and floating objects floating on the surface of the cutting fluid after standing in step S1;

[0039] S3. Pre-filtering: Pour the liquid degreased in step S2 into the filter device 3, and the filter device 3 can pre-filter larger particles of chips and particles inside the liquid;

[0040] S4, demagnetization of the filtrate: the filtrate after the pre-filtration in step S3 enters the inside of the demagnetization device 4, and ...
