[0002] Silicon carbide sand screening machine is a device used to screen and grade silicon carbide particles. Silicon carbide is a hard material with high wear resistance and high temperature stability. It is widely used in abrasives, refractory materials, electronics, aerospace and other fields. During the production process, silicon carbide particles need to be graded according to different particle sizes for subsequent processing and application. The sand screening machine mainly uses the vibration of the screen and the dead weight of the particles to screen the silicon carbide particles on the screen and grade particles of different sizes.

[0003] The mesh plate is an important component of the sand screening machine. However, the traditional mesh plate still has some shortcomings. For example, its anti-clogging ability is poor, so it is very easy to cause mesh clogging due to the bonding and agglomeration of silicon carbide when screening sand, thus affecting the sand screening effect and efficiency. In addition, its structure is relatively fixed, so it is cumbersome, time-consuming and labor-intensive to disassemble it when it needs to be cleaned or maintained. Therefore, in response to the above problems, an anti-clogging silicon carbide sand screening machine mesh plate structure is proposed. Utility Model Content
