Problems solved by technology

[0005] During the whole grinding process, the coolant keeps rotating and flowing so that the iron filings do not settle, and the iron filings are continuously removed, and the coolant is thoroughly purified, which solves the problem of iron filings being oxidized and smelly when they encounter oxygen in the air. Removal of Ferromagnetic Impurities in Efficient Grinding Coolant

Embodiment Construction

[0009] The specific implementation mode that the present invention adopts is:

[0010] First, the coolant is heated to 200-300°C through the heating pipe, flows into the high-pressure furnace, rotates from top to bottom and flows out from the bottom of the high-pressure furnace. There is a filter pad at the bottom of the high-pressure furnace for initial filtration. The filtered coolant passes through the cooling After the pipe is cooled to room temperature, the cooling liquid passes through the magnetic field box. There are magnetized iron plates in the magnetic field box, so that multiple magnetic field spaces are formed in the magnetic field box. When the cooling liquid passes through the water hole in the magnetic field box, it is S Shaped flow, so that the iron filings carried in the coolant are adsorbed on the iron plate. After the coolant flows out of the magnetic field box, it is filtered again through the filter, so that the impurities in the coolant are fully filtered...

Abstract

The invention discloses a cooling liquid demagnetizing and purifying method for grinding, relating to a cooling liquid processing method for grinding in the field of machinery manufacturing, comprising the following steps of: continuously turning the cooling liquid for grinding in rotation during the whole working process to form a vortex; firstly filtering by heating and pressurizing so that iron filings of a magnetic field box body are sucked; and filtering again by the filter to completely filter the impurities in the iron filings in the cooling liquid, so that the cooling liquid is purified thoroughly. In the whole grinding process, the cooling liquid continuously turns in rotation to make the iron filings continuously be removed without depositing and the cooling liquid be thoroughly purified, which solves the problem that the iron filings are oxidized and stink with oxygen in the air. The cooling liquid demagnetizing and purifying method for grinding disclosed by the invention is suitable for removing ferromagnetic impurities in the high-efficiency grinding cooling liquid, has the advantages of good separation effect, high re-utilizing degree of cooling liquid, no need of external cooling liquid discharge, and saving manufacturing cost, and is complete in demagnetization.

Description

technical field [0001] The invention relates to a method for demagnetizing and purifying cooling fluid for grinding, and belongs to the technical field of mechanical manufacturing. Background technique [0002] With the development of the machinery manufacturing industry, the application of mechanical grinding is becoming more and more extensive. The traditional grinding coolant purification treatment mainly adopts isolation sedimentation, paper tape filtration and magnetic separation, which is only suitable for low-efficiency grinding methods with less grinding iron filings, and cannot solve the separation and separation of a large number of iron filings in high-efficiency grinding Excluded, the iron filings from grinding cannot be separated well, which affects the grinding effect; the coolant for high-efficiency grinding is also easy to deteriorate, and the coolant needs to be replaced frequently, which shortens the service life of the coolant and increases the production ...
