[0001] The utility model relates to the technical field of silicon powder production, in particular to a novel high-efficiency silicon powder dryer. Background Art

[0002] Silica powder, also known as microsilica powder, scientifically known as silica fume, is produced by collecting and treating the smoke emitted with the exhaust gas during the high-temperature smelting of industrial silicon and ferrosilicon in industrial electric furnaces through special capture devices.

[0003] Silicon powder is a solid raw material, and the original sample has a certain water content, so the silicon powder needs to be dried by a dryer. In the prior art, most dryers used for silicon powder dry the silicon powder by means of a heating plate. However, since the silicon powder is piled together, the silicon powder is heated unevenly, which affects the drying effect. In addition, a lot of time is required for drying, which reduces the drying efficiency of the device and is not practical enough. Therefore, it is necessary to redesign a new high-efficiency silicon powder dryer to address the above problems. Utility Model Content
