Technical Field

[0001] The utility model relates to the field of kaolin production, in particular to a low-noise iron removal device. Background Art

[0002] Kaolin is a non-metallic mineral, a type of clay and clay rock mainly composed of kaolinite clay minerals. Because it is white and fine, it is also called dolomite.

[0003] The pure kaolin is white, fine, soft and has good physical and chemical properties such as plasticity and fire resistance. Its mineral composition is mainly composed of kaolinite, halloysite, hydromica, illite, montmorillonite, quartz, feldspar and other minerals. Kaolin has a wide range of uses, mainly in papermaking, ceramics and refractory materials, secondly in coatings, rubber fillers, enamel glazes and white cement raw materials, and a small amount in plastics, paints, pigments, grinding wheels, pencils, daily cosmetics, soaps, pesticides, medicines, textiles, petroleum, chemicals, building materials and other industrial sectors.

[0004] In actual use, kaolin needs to be treated to remove iron in order to improve its whiteness. In the prior art, there are many methods for removing iron from kaolin, including chemical methods, such as oxidation, reduction, oxidation-reduction combined method, acid leaching, physical method, etc. The use of chemical methods to remove iron from kaolin will cause pollution to the environment. Environmentally friendly methods of iron removal mostly use physical methods. In the physical method, an electromagnet is used to adsorb the iron-containing particles in the kaolin powder, thereby removing the iron-containing components in the kaolin powder.

[0005] However, when an electromagnet is used to adsorb iron-containing particles in kaolin powder, when the iron-containing particles are wrapped inside the kaolin, part of the kaolin will also be sucked out, resulting in a waste of material.

[0006] Therefore, it is necessary to provide a new low-noise iron removal device to solve the above technical problems. Utility Model Content

[0007] In order to solve the above technical problems, the utility model provides a low-noise iron removal device, which solves the problem that when the iron-containing particles in kaolin powder are adsorbed by electromagnets, when the iron-containing particles are wrapped inside the kaolin, part of the kaolin will be sucked out, thereby causing material waste.
