[0021] Please see Figure 1-5This utility model provides an embodiment of a silicon powder processing device for silicon nitride ceramic production, comprising a processing box 1 and an annular collection box 2. The annular collection box 2 is located on the outer side of the bottom of the processing box 1, and an annular plate 22 is located in the middle position near the top of the annular collection box 2. The annular plate 22 has evenly distributed tooth marks on the side away from the processing box 1, and an inverted T-shaped sweeping brush 16 is located in the middle position of the bottom side of the annular plate 22, with the bristles at the bottom of the sweeping brush 16 adhering to the bottom of the annular collection box 2. A conical filter cover 12 is provided between the inner walls of the lower middle part of the processing box 1, and an inverted conical discharge cover 17 is provided between the bottom of the filter cover 12 and the inner walls of the processing box 1. A rotating tube 4 is located between the discharge cover 17 and the filter cover 12 via a bearing. Both sides of the rotating tube 4 near the top are provided with oblique brushes 13, and the bristles of the oblique brushes 13 are in close contact with the filter cover 12. A feeding groove 24 is provided on the rotating tube 4 between the oblique brushes 13. A central rod 18 is provided at the middle of the top of the rotating tube 4, and material-tapping plates 19 are evenly distributed on the outer side of the central rod 18. A downward-sloping feeding groove is evenly distributed on the top of the central rod 18. An outer cover 3 is provided at the bottom of the processing box 1 corresponding to the position of the rotating tube 4. A motor 5 is provided on the bottom side of the outer cover 3 away from the rotating tube 4, and the output end of the motor 5 extends through a bearing into the outer cover 3 where a gear 15 is located. The bottom end of the rotating tube 4 extends through a bearing to the bottom of the outer cover 3, and a gear 14 is provided on the rotating tube 4 inside the outer cover 3. Gear 14 and gear 15 are mutually... The annular collecting box 2 has two motors 6 located on both sides away from the middle of the processing box 1. The output end of motor 6 extends through bearings to a gear 23 located between the annular support plate 20. The gear 23 meshes with the toothed teeth of the annular plate 22. A feeding hopper 7 is located at the middle of the top of the processing box 1, and a guide cover 11 is located at the top of the processing box 1 corresponding to the feeding hopper 7. A sloping annular opening is located at the connection between the processing box 1 and the annular collecting box 2. A discharge pipe is located at the middle of one side of the bottom of the annular collecting box 2, allowing material to enter the processing box 1 through the feeding hopper 7 and the guide cover 11 for crushing and grinding. Then, motor 5 can be started, causing motor 5 to drive gear 15 on its shaft to rotate. Gear 15 then drives gears meshing with it... Gear 14 rotates, driving the rotating tube 4 to rotate. This causes the central rod 18 at the top of the rotating tube 4 to rotate the material-tapping plate 19, which then taps the ground material onto the filter cover 12. Simultaneously, material falling onto the central rod 18 rotates and falls through the feed chute, then passes through the filter cover 12 for filtration. The rotating tube 4 also drives the inclined brush 13 to rotate and clean the filter cover 12, improving its filtration effect. Larger materials can then enter the rotating tube 4 through the discharge chute 24, be discharged through the rotating tube 4, and collected for re-grinding. After filtration, the material can be guided through the discharge cover 17 to the annular opening for discharge. Then, motor 26 can be started, driving gear 3 23 on its shaft to rotate. Gear 3 23 drives the annular plate 22 meshing with it to rotate.The annular plate 22 drives the sweeping brush 16 on one side of the bottom to rotate and clean the annular collection box 2, which can sweep the material in the annular collection box 2 to the discharge pipe, facilitating the discharge and collection of the ground and filtered material;

[0022] Inside the processing box 1, near the top center, there are intermeshing crushing rollers 8 connected by a crushing shaft. Below the crushing rollers 8, inside the processing box 1, there are grinding rollers 9 connected by a grinding shaft. Cleaning blocks 10 are provided on the inner walls of the processing box 1 outside both the grinding rollers 9 and the crushing rollers 8. The bristles of the cleaning blocks 10 are respectively attached to the corresponding grinding rollers 9 and crushing rollers 8. After the silicon powder material enters the processing box 1, the crushing rollers 8 can be driven by a drive motor to rotate relative to each other to crush the material. Then, the grinding rollers 9 can be driven by a drive motor to rotate relative to each other to grind the crushed material. During crushing and grinding, the bristles of the cleaning blocks 10 can clean the outer surface of the material to prevent excessive material adhesion, which would affect the crushing and grinding effect.

[0023] Both sides of the annular plate 22 have annular support plates 20 inside the annular collection boxes 2 at the top and bottom. The annular support plates 20 are equipped with sliding balls 21 on the inner side of the annular support plates 20 corresponding to the position of the annular plate 22. The other side of the sliding balls 21 are in contact with the annular plate 22. When the annular plate 22 rotates, the annular support plates 20 and sliding balls 21 can support it, making the rotation of the annular plate 22 more stable.

[0024] In this embodiment, silicon powder is fed into the processing box 1 through the feeding hopper 7 and the guide cover 11. The drive motor then drives the crushing drum 8 to rotate relative to each other, crushing the material. The drive motor then drives the grinding drum 9 to rotate relative to each other, grinding the crushed material. During crushing and grinding, the bristles of the cleaning block 10 clean the outer surface, preventing excessive material adhesion and affecting the crushing and grinding effect. Then, the motor 5 is started, driving the gear 15 on its shaft to rotate. The gear 15 drives the meshing gear 14 to rotate, which in turn drives the rotating tube 4 to rotate. This causes the central rod 18 at the top of the rotating tube 4 to rotate the material-tapping plate 19, tapping the ground material onto the filter cover 12. Simultaneously, material falling onto the central rod 18 is allowed to fall through the rotating feed chute. The material is filtered through the filter cover 12, and the rotating tube 4 drives the inclined brush 13 to rotate and clean the filter cover 12, thus improving the filtration effect. Larger materials can then enter the rotating tube 4 through the feed chute 24, and be discharged and collected for re-grinding. After filtration, the material can be guided to the annular opening through the feed cover 17 for discharge. Then, the motor 26 can be started to drive the gear 3 23 on its shaft to rotate. The gear 3 23 drives the annular plate 22 that meshes with it to rotate. When the annular plate 22 rotates, the annular support plate 20 and the sliding ball 21 can support it, making the rotation of the annular plate 22 more stable. Then, the annular plate 22 can drive the sweeping brush 16 on the bottom side to rotate and clean the annular collection box 2, which can sweep the material in the annular collection box 2 to the feed tube, making it convenient to discharge and collect the ground and filtered material.

[0025] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
