Technical Field

[0001] This utility model belongs to the field of silicon carbide particle separation technology, and specifically relates to a silicon carbide particle separation device for silicon wafers. Background Technology

[0002] Silicon carbide particles are third-generation semiconductor materials composed of carbon and silicon elements. They have high hardness, high thermal conductivity, wide bandgap, and excellent chemical stability. Before processing, silicon carbide particles need to be further crushed using a pulverizer to reduce the particle diameter.

[0003] The aforementioned device lacks a structure for separating and secondary crushing of silicon carbide particles after crushing. As a result, when silicon carbide particles are crushed using a pulverizer, some of the silicon carbide particles cannot reach the required diameter after crushing and are mixed with the qualified particles. This not only affects subsequent processing but also adds a cumbersome step of sieving the particles separately. Based on the shortcomings of the existing technology, this utility model designs a silicon carbide particle separation device for silicon wafers. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] Please see Figure 1-5 The present invention provides the following technical solution: a silicon carbide particle separation device for silicon wafers, including a particle separator 1, a fixing strip 2 fixedly connected to one side of the particle separator 1, and a lifting mechanism 3 provided at the bottom of the particle separator 1;

[0026] The bottom of the particle separator 1 is fixedly connected to a support foot 101, and the top of the particle separator 1 is fixedly connected to a feed hopper 102.

[0027] The fixing strip 2 is internally fixedly connected to a fixing pipe 201. A feed pipe 202 is fixedly connected to one side of the fixing pipe 201, and a discharge pipe 203 is fixedly connected to one side of the fixing strip 2.

[0028] The fixed pipe 201 is set on one side of the particle separator 1, and the feed pipe 202 is fixedly connected to one side of the connecting cylinder 303.

[0029] The feed pipe 202 is located on one side of the screen 302, and the discharge pipe 203 is located inside the feed hopper 102.

[0030] Further explanation is needed: silicon carbide particles for silicon wafers are fed into the particle separator 1 from the feed hopper 102. After being processed and crushed, they are screened by the lifting mechanism 3. The silicon carbide particles that do not meet the standards are lifted back into the feed hopper 102 for further crushing.

[0031] Example 2

[0032] Please see Figure 2-5 The present invention provides the following technical solution:

[0033] The lifting mechanism 3 includes a feeding cylinder 301, a screen 302, a connecting cylinder 303, a motor 304, and an auger 305. The feeding cylinder 301 is located at the bottom of the particle separator 1. The screen 302 is fixedly connected inside the feeding cylinder 301. The connecting cylinder 303 is fixedly connected to one side of the feeding cylinder 301. The motor 304 is located on one side of the particle separator 1. The auger 305 is located at the bottom of the motor 304.

[0034] The feed cylinder 301 is located on one side of the support foot 101, and the screen 302 is located at the bottom of the particle separator 1.

[0035] The connecting cylinder 303 is located on one side of the screen 302, and the motor 304 is located on the top of the fixing strip 2.

[0036] The auger 305 is located inside the fixed bar 2 and is located on one side of the feed pipe 202.

[0037] Further explanation is needed: After being crushed inside the particle separator 1, the particles fall into the feed cylinder 301 and are screened by the screen 302 inside the feed cylinder 301. The screened particles fall directly from the feed cylinder 301 for collection, while the particles that do not meet the screening standards slide from the screen 302 into the connecting cylinder 303 and then into the feed pipe 202. At this time, the screw conveyor 305 lifts the particles that do not meet the screening standards and makes them enter the feed hopper 102 for further processing through the fixed pipe 201 and the discharge pipe 203.

[0038] Working principle: When a silicon carbide particle separation device is used, the silicon carbide particles are first fed into the particle separator 1 from the feed hopper 102. After being processed and crushed, they are screened by the lifting mechanism 3. The silicon carbide particles that do not meet the standards are lifted back into the feed hopper 102 for further crushing.

[0039] When the crushed particles need to be separated again, the crushed particles first fall into the feed cylinder 301 inside the particle separator 1 and are screened by the screen 302 inside the feed cylinder 301. The screened particles fall directly from the feed cylinder 301 for collection, while the particles that do not meet the screening standards slide from the screen 302 into the connecting cylinder 303 and then into the feed pipe 202. At this time, the screw conveyor 305 lifts the particles that do not meet the screening standards and makes them enter the feed hopper 102 for further processing through the fixed pipe 201 and the discharge pipe 203. This device facilitates the further separation of crushed particles.
