Novel efficient multi-functional dual-roller magnetic separator

Abstract

The invention discloses a novel efficient multi-functional dual-roller magnetic separator. The novel efficient multi-functional dual-roller magnetic separator comprises a main machine frame and a base arranged at the bottom of the main machine frame. An angle adjusting device is arranged between the main machine frame and the base. A magnetic separation body assembly is arranged on the main machine frame and comprises a coil and an iron core arranged inside the coil. The coil is powered on to form an electromagnetic pole. A left magnetic separation device is arranged on the left side of the iron core, and a right magnetic separation device is arranged on the right side of the iron core. The left magnetic separation device and the right magnetic separation device each comprises a roller fixing ring and a magnetic separation roller arranged in the roller fixing ring. Each magnetic separation roller is internally provided with a magnetic yoke. Magnetic yokes in bridge connection with a magnetic circuit are arranged on the two sides of the left magnetic separation device and the two sides of the right magnetic separation device. The overall design is reasonable; the inclination angle of the magnetic separation body assembly can be adjusted according to production needs; and materials are turned over up and down in the magnetic separation roller, so that magnetic impurities in the materials are fully sucked out, the whole process is completed automatically, and the magnetic separation effect is improved by 60% or over compared with that of a traditional magnetic separation machine.

Description

technical field [0001] The invention relates to the technical field of iron removal machinery, in particular to a novel high-efficiency multifunctional double-drum magnetic separator. Background technique [0002] In the production raw materials of ceramics, cement and some ores, since the content of iron in the earth’s crust is at a relatively high level, fine particles such as iron powder and iron slag are easily mixed in the powder or slurry, especially when the quality of the ore source is not high. If such iron impurities are not removed before processing, it will affect the quality of the products made of the above raw materials. For example, if the iron removal treatment is not carried out before firing ceramic tiles and porcelain, the iron will cause The color of the product is darker than expected. Excessive iron filings will form black spots or pinholes on the surface of the porcelain after firing, which will greatly affect the surface effect of the product. Durin...

Problems solved by technology

[0002] In the production raw materials of ceramics, cement and some ores, since the content of iron in the earth’s crust is at a relatively high level, fine particles such as iron powder and iron slag are easily mixed in the powder or slurry, especially when the quality of the ore source is not high. If such iron impurities are not removed before processing, it will affect the quality of the products made of the above raw materials. For example, if the iron removal treatment is not carried out before firing ceramic tiles and porcelain, the iron will cause The color of the product is darker than expected. Excessive iron filings will form black spots or pinholes on the surface of the porcelain after firing, which will greatly affect the surface effect of the product. During the manufacturing process, it is prone to cracking, damage, etc., resulting in the problem that the production and processing cannot be completed

[0003] In order to solve these problems, at present, the magnetic separators on the market are mainly two types: permanent magnet and electromagnetic iron removers. , currently still in the manual unloading stage

It is difficult to unload iron with a large volume and weight in this way. At the same time, the safety of personnel cannot be guaranteed during use. It is not suitable for automatic control and is only suitable for use in small-scale occasions; The rotating drum sucks out the magnetic impurities in the mixed material, but after the traditional drum magnetic separator absorbs the magnetic impurities in the powder, some magnetic impurities with strong magnetic force cannot be effectively removed by the drum under the action of the magnetic field force. When it is taken out, it will still be adsorbed on the wall of the magnetic drum. When the adsorbed magnetic miscellaneous material is too thick, it will interfere with the magnetism, causing the newly entered magnetic miscellaneous material to be unable to be adsorbed on the magnetic drum, resulting in magnetic separation. Low efficiency, incomplete magnetic separation
