Description

Technical Field

[0001] The utility model relates to the technical field of demagnetization devices, in particular to a high-efficiency device for removing magnetic materials from electronic-grade nano powder materials. Background Art

[0002] In the field of electronic materials, barium carbonate is one of the most important raw materials for preparing dielectric materials in multilayer ceramic capacitors (MLCC). With the advancement of science and technology and the expanding application field of barium carbonate, as well as the trend of electronic products towards miniaturization, ultra-thinness and portability, the corresponding MLCC is also developing towards miniaturization and thin-layer, requiring the raw materials for producing dielectric materials to be at the nanometer level, and companies have increasingly higher requirements for the quality of barium carbonate crystals. Therefore, in the production of barium carbonate powder materials, the magnetic impurities in it must be removed. Traditional demagnetization devices directly contact the barium carbonate powder through a magnetic rod, and use the magnetism of the magnetic rod to adsorb the magnetic impurities in it. However, when the barium carbonate powder enters the traditional demagnetization device, due to extrusion and agglomeration during transmission, the agglomerated barium carbonate powder is squeezed and agglomerated when it contacts the magnetic rod, and the magnetic impurities inside are wrapped, which is not conducive to the adsorption of the magnetic rod, and the demagnetization efficiency is low, and repeated material return is required for adsorption operations.

[0003] The present application designs a highly efficient device for removing magnetic materials from electronic-grade nano-powder materials, which can break up agglomerated barium carbonate powder in advance and then adsorb it through a demagnetization device to improve the removal efficiency of magnetic impurities in the barium carbonate powder.
