Description
Technical Field

[0002] Silicon carbide, also known as emery, is made by high-temperature smelting of raw materials such as quartz sand, petroleum coke, and wood chips in an electric resistance furnace. It has stable chemical properties, high thermal conductivity, low thermal expansion coefficient, and good wear resistance. Therefore, in addition to being used as an abrasive, it can also be used to improve the wear resistance of impellers or cylinder blocks and as high-grade refractory materials, etc., with wide applications.
[0003] Since the natural content of silicon carbide is small, it is mainly produced artificially. The most common method in the prior art is to mix quartz sand and coke, then add salt and wood chips, and finally place them in an electric furnace for high-temperature heating. Through a chemical process, silicon carbide can be obtained. Obviously, in the preparation process, it is necessary to mix the raw material components in a determined proportion. In the prior art, most of them are weighed in advance and then uniformly poured into a mixing reactor for mixing, and finally put into an electric furnace. However, this method requires manual repeated weighing, which will undoubtedly consume a large amount of manpower and material resources, and at the same time increase the processing and preparation time.

[0006] As a further scheme of the utility model: A first limit ring is fixed on the top of the first frame, and a second limit ring is fixed on the top of the second frame.
