Description

Technical Field

[0001] The present application relates to the technical field of magnetic separators, and in particular to an automatic electromagnetic magnetic separator for powder materials. Background Art

[0002] Magnetic separator is a screening device used to remove iron powder from recycled powder particles. After the slurry flows into the tank through the feed box, the ore particles enter the feeding area of the tank in a loose state under the action of the water flow of the feed water pipe. Under the action of the magnetic field, the magnetic ore particles are magnetically gathered to form "magnetic clusters" or "magnetic chains". The "magnetic clusters" or "magnetic chains" are affected by the magnetic force in the slurry and move toward the magnetic poles and are adsorbed on the cylinder. Since the polarity of the magnetic poles is arranged alternately along the rotation direction of the cylinder and is fixed during operation, the "magnetic clusters" or "magnetic chains" produce magnetic stirring due to the alternation of magnetic poles when the "magnetic clusters" or "magnetic chains" rotate with the cylinder. Non-magnetic minerals such as gangue mixed in the "magnetic clusters" or "magnetic chains" fall off during the turning, and the "magnetic clusters" or "magnetic lotuses" that are finally adsorbed on the surface of the cylinder are the concentrates. Magnetic separators are widely used in resource recycling, wood industry, mining industry, kiln industry, chemical industry, food industry and other factories. They are suitable for wet magnetic separation of magnetite, pyrrhotite, roasted ore, ilmenite and other materials with a particle size below 3mm. They are also used for iron removal of coal, non-metallic minerals, building materials and other materials. They are one of the most widely used and versatile machines in the industry.

[0003] Through searching, Chinese patent announcement number CN218796502U discloses a magnetic separation mechanism of a magnetic separator, including a magnetic separation box, the top of the magnetic separation box is fixedly connected with a box body, the top of the magnetic separation box is fixedly connected with a feed hopper, a uniform feeding assembly is arranged between the box body, the magnetic separation box and the feed hopper, and the inner walls on both sides of the magnetic separation box are fixedly connected with slide rails. The utility model has the following advantages and effects: through the left and right reciprocating shaking of the material balancing plate, the powder can be evenly dispersed and discharged from multiple material balancing holes, avoiding the accumulation of powder and reducing the magnetic separation effect on iron powder. Through the cooperation of the slide rail, the mounting frame, the lock slot, the lock rod, the extrusion spring and the connecting rod, it is convenient to disassemble and assemble the mounting frame, so as to pull out the electromagnetic rod, and then cut off the power of the electromagnetic rod, so that the electromagnetic rod loses its magnetism, and the iron powder on the electromagnetic rod automatically falls off, so as to facilitate the cleaning of the iron powder adsorbed on the electromagnetic rod.
