Description

Technical Field

[0001] The utility model relates to the technical field of silicon carbide mixing equipment, in particular to a horizontal dry mixing mixer. Background Art

[0002] Silicon carbide is an inorganic substance, which is smelted at high temperature in a resistance furnace with raw materials such as quartz sand, petroleum coke, and wood chips. Silicon carbide also exists as a rare mineral in nature. Among non-oxide high-tech refractory raw materials such as C, N, and B, silicon carbide is the most widely used and economical one, and can be called carborundum or refractory sand.

[0003] At present, when manufacturing silicon carbide, the materials need to be ground and then mixed and stirred, which is beneficial to the manufacture of crucibles. However, when adding materials into the mixing tank, due to the relatively fine particle size of silicon carbide, it is easy to adsorb together or adsorb at the mixing dead corners of the mixing tank, resulting in the mixing paddle blades being unable to reach these positions, making it difficult to achieve the expected mixing and stirring effect. The mixing and stirring process takes a long time and the mixing is uneven, resulting in a low yield of the mixed products. Summary of the Utility Model

[0004] The utility model provides a horizontal dry mixing mixer, which solves the problems of long time consumption, uneven mixing, and low yield of the mixed products in the traditional silicon carbide dry mixing mixer during the mixing and stirring process.
