Technical Field

[0001] The utility model relates to the field of silicon micropowder, in particular to silicon micropowder purification equipment. Background Art

[0002] Silica powder is a non-toxic, tasteless, pollution-free inorganic non-metallic material. It is widely used in chemical industry, electronics, integrated circuit (IC), electrical appliances, plastics, coatings, advanced paints, rubber, national defense and other fields due to its excellent properties such as good temperature resistance, acid and alkali corrosion resistance, high thermal conductivity, high insulation, low expansion, stable chemical properties and high hardness. With the rapid development of high-tech fields, silica powder will also enter a new historical development period. Silica powder is a micropowder made of natural quartz (SiO2) or fused quartz (amorphous SiO2 after natural quartz is melted at high temperature and cooled) through multiple processes such as crushing, ball milling (or vibration, air flow milling), flotation, acid washing and purification, high-purity water treatment, etc. Among them, acid washing is one of the most important steps in the production of silica powder.

Next, when the purification equipment is used, silicon micropowder can be added into the purification box 4 from the feed hopper 19. When the silicon micropowder enters the feed box 8, the crushing roller 13 and the crushing roller ring 14 rotating in opposite directions will further crush the large particles inside the silicon micropowder to increase its contact area with the pickling solution. In the process of the silicon micropowder being crushed, the iron filings mixed in the silicon micropowder will be adsorbed on the surface of the crushing roller ring 14 under the action of the electromagnet 15.
