Magnetic separation device

Abstract

The invention discloses a magnetic separation device. The problem that in the prior art, liquid and iron filings cannot be better effectively separated is solved. According to the technical scheme main point, the magnetic separation device comprises a placement frame; a mandrel is placed in the placement frame; a magnet block with a helical path is mounted on the outer surface of the mandrel; the mandrel is sleeved with a conveying cylinder; a gap is arranged between the conveying cylinder and the mandrel; the two ends of the conveying cylinder are fixed to the placement frame; one end of the mandrel is placed below a liquid outlet, and the other end of the mandrel is provided with a motor to drive the mandrel to conduct autorotation along the axis; a scraper used for scraping the surface of the conveying cylinder is arranged at the end, close to the motor, of the placement frame; and a spiral-shaped magnet of the scraper can drive an iron block on the surface of the placement frame to move in the direction of the conveying cylinder to one end of the motor, so that scraping on an iron piece or the iron filings can be achieved through the scraper, full automatic separation is achieved, and cleaning in time is achieved in the whole process.

Description

technical field [0001] The invention relates to a filtering device in mechanical processing, in particular to an iron filings separation device for liquid in mechanical processing. Background technique [0002] In the various processing processes of machinery, it is necessary to cut the material, such as grinding machines, wire cutting, cold heading machines, etc., all involve changing the shape of the material through cutting, and in cutting, etc. A lot of heat will be generated during the processing. At present, coolant is usually used for cooling during the cutting process, and a lot of electric corrosion products (including many iron filings and small iron pieces, etc.) will be generated during the cutting process. , and these products are washed away by the cooling liquid and mixed into the cooling liquid. The cooling liquid is recycled on the machine, so the filtration of the cooling liquid is essential. At present, the cooling liquid is usually filtered by paper core...

Problems solved by technology

But the method is only when the coolant passes through the magnetic filter table, the iron filings are adsorbed on the chute during the passage, and the electromagnet is turned off when cleaning is required to realize cleaning, but the iron filings on the magnetic filter table After the increase, the adsorption capacity of the electromagnet to the coolant flowing through the magnetic filter table is reduced, and the adsorption efficiency is greatly reduced, and the switching between the two modes cannot be fully automated
