A mixing barrel 3 is installed inside the support frame 2, and the support frame 2 supports and stabilizes the mixing barrel 3. A barrel cover 4 is threadedly installed on the top of the mixing barrel 3, and a feeding hopper 5 is installed on the left side of the mixing barrel 3. The silicon carbide raw material that needs to be stirred and mixed is poured from the feeding hopper 5. The feeding hopper 5 is convenient for adding materials, and the silicon carbide raw material enters the mixing barrel 3. A first motor 6 is installed on the upper surface of the barrel cover 4, and a support plate 7 is connected to the output end of the first motor 6. Motors 8 are installed on both ends of the upper surface of the support plate 7, and cutting blades 9 are connected to the output end of the motor 8. Turn on the first motor 6, and the first motor 6 drives the support plate 7 to rotate, thereby driving the support plate 7 to rotate, and then turn on the motor 8, and the motor 8 drives the cutting blades 9 to rotate in the opposite direction. The cutting blades 9 cut and disperse the silicon carbide raw materials, which is convenient for subsequent raw materials to be fully stirred and mixed;

[0024] A filter plate 10 is installed inside the mixing barrel 3. After the silicon carbide raw material is cut and dispersed, it is filtered through the filter plate 10. The silicon carbide raw material that meets the aperture enters the lower cavity of the mixing barrel 3, and the larger silicon carbide raw material continues to be cut and dispersed. A second motor 11 is installed in the middle of the filter plate 10. A stirring blade 12 is connected to the output end of the second motor 11.
