Description

Technical Field

[0001] The utility model relates to the technical field of refractory materials, in particular to an iron removal device for refractory material powder. Background Art

[0002] Refractory materials are a type of inorganic non-metallic materials with a refractoriness of not less than 1580℃. Refractory materials are widely used in metallurgy, chemical industry, petroleum, machinery manufacturing, silicate, power and other industrial fields. The largest amount is used in the metallurgical industry, accounting for 50% to 60% of the total output. Refractory materials include high-temperature resistant materials such as corundum powder, quartz powder, bauxite powder, mullite powder, etc. Refractory materials are mostly produced by crushing and processing raw materials or recycled refractory materials. Both raw materials and recycled waste refractory materials contain iron. If the iron content is too high, it will affect the quality of the refractory materials and will also have an adverse effect on castings. Therefore, in the production process of refractory materials, they need to be crushed and screened first, and then iron removal equipment is used to remove iron.

[0003] However, in the existing refractory material iron removal device, after the magnet adsorbs the iron powder, the iron on the surface of the magnet cannot be removed. As more and more iron is adsorbed on the surface of the magnet, the magnet's suction force will decrease, and after a long period of use, a good adsorption effect cannot be achieved.
