[0033] The technical solutions of the present application will be described in detail below with reference to the accompanying drawings. Figs. 1-3 The embodiments of the technical solutions of the present application will be described in detail below. The following embodiments are only used to more clearly illustrate the technical solutions of the present application, and therefore only serve as examples, and cannot limit the protection scope of the present application. In addition, the technical features involved in the various embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0034] Embodiment one:

[0035] As Figs. 1-2 The present application illustrates a silicon carbide micro-powder spheroidization treatment device. In order to improve the falling efficiency of silicon carbide micro-powder and solve the problem of low feeding rate, the present application proposes a silicon carbide micro-powder spheroidization treatment device, which reduces the adhesion of silicon carbide micro-powder falling on the sieve plate by setting a conical sieve plate 7. The design of the conical sieve plate makes it easier for the material to slide down along its conical surface. At the same time, a wave-shaped guide plate 93 is arranged at the top of the circumferential edge of the conical sieve plate 7, which cooperates with the work of the shaking component 9 to make the conical sieve plate 7 vibrate multiple times when the motor 91 rotates one circle. This design not only does not block the falling of silicon carbide micro-powder, but also effectively promotes the crushing of silicon carbide agglomerates into micro-powder through multiple vibrations, thereby improving the efficiency of micro-powder entering the feeding pipe 4. This improvement effectively solves the problem of low feeding rate of the ball mill in the prior art.

[0036] Embodiment two:

[0037] Please refer to Fig. 2, in order to make the conical sieve plate continuous up and down to increase the falling efficiency of silicon carbide powder, the shaking part 9 of the application includes a motor 91, a rotating shaft 92, a wave-shaped guide plate 93, a lever 94 and a telescopic device 95. The end of the lever 94 is placed between the wave crest and wave trough of the wave-shaped guide plate 93, when the motor 91 drives the rotating shaft 92 to rotate, the lever 94 rotates and moves along the wave-shaped trajectory of the wave-shaped guide plate 93, driving the conical sieve plate 7 to continuously shake up and down. This continuous shaking makes the silicon carbide powder on the conical sieve plate 7 constantly stimulated, further increasing the falling efficiency of the powder. The setting of the wave-shaped guide plate 93 ensures that the shaking part 9 realizes effective vibration effect without blocking the falling of the material.

[0038] Embodiment three:

[0039] Please continue to refer to Fig. 2 , in order to prevent the silicon carbide powder from affecting the compression performance of the spring, the telescopic device 95 of the application includes a pre-compression spring 951 arranged in the vertical direction and a telescopic sleeve 952 covering the pre-compression spring 951. The pre-compression spring 951 is used to provide the power for the shaking of the conical sieve plate 7, while the telescopic sleeve 952 effectively prevents the silicon carbide powder from directly falling on the spring, thereby avoiding the problem that the spring loses compression performance due to the accumulation of powder. This design ensures the long-term stable work of the spring, and further ensures the reliability and durability of the shaking part 9.

[0040] Embodiment four:

[0041] Please refer to Fig. 3 , in order to make the crushing part fit the surface of the conical sieve plate and improve the crushing effect, the crushing part 8 of the application is connected and installed on the rotating shaft 92 through the first symmetrical fixed plate 81 and the second symmetrical fixed plate 86, and can adjust its opening angle according to the taper of the conical sieve plate 7. The support rod 82 is connected to the first symmetrical fixed plate 81 through a pin, and is connected to the cleaning brush 83 and the grinding roller 84 respectively. The cleaning brush 83 and the grinding roller 84 are tightly attached to the surface of the conical sieve plate 7, and the compression rod 87 is in a compressed state, so that the crushing part 8 can better fit the surface of the sieve plate. This design not only improves the crushing effect, but also avoids the problem of poor crushing effect caused by uneven sieve plate. The synergistic effect of the grinding roller 84 and the cleaning brush 83 further promotes the crushing of silicon carbide agglomerates and the generation of fine powder.

[0042] In summary, the silicon carbide powder spheroidization treatment device of the application realizes efficient spheroidization treatment of silicon carbide powder through the synergistic effect of the conical sieve plate, the shaking part and the crushing part, and improves the feeding rate and grinding efficiency of the ball mill.
