Description

Technical Field

[0001] The utility model relates to silicon powder pretreatment equipment and belongs to the technical field of silicon powder pretreatment. Background Art

[0002] Silica powder, also known as microsilica powder, scientifically known as silica fume, is the smoke and dust that escapes with the exhaust gas during the high-temperature smelting of industrial silicon and ferrosilicon in industrial electric furnaces, and is collected and processed by special capture devices. In the escaped smoke and dust, the SiO2 content accounts for about 90% of the total smoke and dust, and the particle size is very small, and the average particle size is almost nanometer level, so it is called silicon powder.

[0025] In this embodiment, the driving assembly 4 includes a forward and reverse motor 41 and a driven gear 44. The forward and reverse motor 41 drives the connecting shaft 42 to rotate, and then the connecting shaft 42 drives the driving gear 43 to rotate. Because the driving gear 43 and the driven gear 44 are meshed, the driven gear 44 can be driven to rotate at the same time.
