Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of silicon carbide production, specifically to a purification device for silicon carbide powder. BACKGROUND

[0002] Silicon carbide is an inorganic substance with the chemical formula SiC, which is made from quartz sand, petroleum coke (or coal coke), wood chips (salt is needed when producing green silicon carbide), and other raw materials through high-temperature smelting in an electric resistance furnace. Silicon carbide also exists as a rare mineral in nature, called moissanite. During the production, processing, and manufacturing of silicon carbide, dust and other foreign matter inevitably mix in the produced silicon carbide powder. Therefore, purification and dust removal are usually required to obtain relatively pure silicon carbide powder.

[0003] However, during the purification and dust removal process, the powder sucked into the device may be mixed with larger dust particles, which may affect the normal operation of the device and cause damage to the equipment. To address this issue, a purification and dust removal device for recrystallized silicon carbide powder is disclosed in Chinese Patent Publication No. CN217662147U. The main function of this device is to grind the dust particles inside the equipment using a grinding plate and then purify and discharge them, preventing larger particle dust from damaging the equipment. However, during long-term use, the surface of the grinding plate may wear out, resulting in a shorter service life of the device. Moreover, during use, dust may easily adhere to the filter plate, reducing the filtering effect and the purification and dust removal effect of the device.

[0004] To address this issue, we propose a purification device for silicon carbide powder. UTILITY MODEL CONTENTS
