Description

An additive structure for preparing high-purity silicon carbide Technical Field

[0001] This utility model relates to the technical field of additive structure for preparing high-purity silicon carbide, and particularly to an additive structure for preparing high-purity silicon carbide. Background Technology

[0002] Existing feeding structures often directly add raw materials into the reactor through a feed pipe. However, when the temperature and pressure inside the reactor are high, the added raw materials are sprayed out due to the pressure difference between the inside and outside of the reactor, resulting in material splashing. This is not suitable for the preparation of silicon carbide. For example, Chinese patent disclosure "A high-temperature resistant silicon carbide production reactor" (application number: CN201922088120.2) includes a base with a rotating structure installed on the upper wall of the base. The rotating structure is equipped with a stirring structure. This structure facilitates use, but during use, the added raw materials are sprayed out due to the pressure difference between the inside and outside of the reactor, resulting in material splashing.
