Magnetic filter for high-precision machining field

Abstract

The invention discloses a magnetic filter for the field of high-precision machining, and relates to a ferromagnetic waste filter, which comprises at least two filtering tanks, wherein the filtering tank comprises a liquid inlet and a liquid outlet formed above the liquid inlet, a lining sleeve is arranged in the filtering tank in a sealing manner, a strong magnetic rod capable of sliding up and down is arranged in the lining sleeve, the ferromagnetic waste filter further comprises a cleaner, the cleaner comprises a treatment chamber, a cleaning liquid inlet, a cleaning liquid outlet and a slagdischarge port are formed in the treatment chamber, a magnetic rolling shaft and a scraping plate matched with the magnetic rolling shaft are arranged in the treatment chamber, and the scraping plateis communicated with the slag discharge port. Compared with the prior art, the ferromagnetic waste filter of the invention has the following characteristics that submicron iron-containing impuritiescan be effectively removed, long-time continuous uninterrupted operation can be truly achieved, a filtering loop and an impurity discharging loop are not collinear, and it is guaranteed that the filtering loop is still free of pollution after ultra-long-time operation.

Description

technical field [0001] The invention relates to a filter for ferromagnetic waste materials, in particular to the filtration of tiny ferromagnetic waste materials in fluid media. Background technique [0002] In the various processing of ferromagnetic materials, a large amount of industrial fluid media such as coolant and cutting fluid are required. These fluid media contain a large amount of ferromagnetic impurities after use. In order to save costs, these fluid media are usually filtered and recycled. The existing filtration methods mainly include barrier filtration, sedimentation filtration, vortex separation filtration, vacuum filtration, etc. The barrier filtration accuracy is between 10 microns and 20 microns, and the filter material needs to be replaced frequently. Sedimentation filtration cannot remove tiny particles. In most cases, vortex separation filtration cannot remove impurities smaller than 10 microns. Vacuum filters can remove particles of about 1 micron . ...

AI Technical Summary

Problems solved by technology

However, in the existing magnetic filtration system, the fluid medium circulation loop and the impurity discharge loop are partly collinear, and different iron removal methods are used for filtration and discharge, and the iron removal effects are different. After long-term operation, the fluid medium circulation loop will be polluted and affect The effect of high-precision machining
