Background

In the cutting fluid in which a large amount of scrap iron to be cut is mixed during the operation of the lathe, the scrap iron in the cutting fluid needs to be purified because the cutting fluid is recycled. With the improvement of machining precision, high-speed grinding and powerful grinding technologies are rapidly developed, and besides reasonable grinding parameters are selected, the circulation quality of grinding fluid must be improved. The existing cutting fluid purifiers are mainly filter purifiers which remove impurities by filter media, such as filter screens, linear gap filters, sheet filters and paper belt filters. In order to avoid the accumulation of scrap iron, the filtering purifier needs to be cleaned regularly, is very troublesome to use, has poor purifying effect on cutting fluid, and can cause adverse effect on the normal use of a machine tool.

Chinese patent No. CN203264855U discloses a machine tool cutting fluid purifier, which includes a frame, a magnetic roller and a rubber roller are arranged on the frame, the magnetic roller and the rubber roller are arranged oppositely, the magnetic roller is connected with a driving motor through a transmission mechanism, a scraper is further arranged on one side of the magnetic roller, and the scraper is attached to the magnetic roller. When dirty cutting fluid flows through a magnetic roller adsorption area which rotates slowly, magnetic solid particles are magnetized under the action of a magnetic field, adsorbed to the surface of the magnetic roller and taken out of a cutting fluid flowing area, extruded and dehydrated by a rubber roller, and scrap iron on the magnetic roller is scraped by a scraper attached to the magnetic roller. The machine tool cutting fluid purifier can realize automatic separation of ferromagnetic substances, keep the cutting fluid clean, improve the processing performance and the service life of a cutter, and reduce environmental pollution; the machine tool cutting fluid purifier also has the advantages of simple structure and convenient use.

The magnetic roller of above-mentioned patent includes a magnet portion and a rubber portion, magnet portion follows 270 distributions of magnetic roller circumference, rubber portion follows 90 distributions of magnetic roller circumference to iron fillings separate with the magnetic roller, but such structure, when the relative magnetic roller of scraper blade was scraped, the scraper blade need promote iron fillings and can make iron fillings and magnetic roller throw off after reaching the rubber portion by magnet portion, and at this in-process, magnetic force between iron fillings and the magnet portion produced great resistance to the scraper blade, and the required moment of motor and consumption are great relatively like this, and power consumption is also more. On the other hand, when the cutting fluid flows through, the cutting fluid is not adsorbed if the cutting fluid is just in contact with the rubber portion, and thus it is difficult to ensure a good cleaning effect of the cutting fluid.
