[0002] As a new type of functional material, carbon nitride materials are widely used in fields such as energy conversion, environmental governance, and new material development due to their excellent photocatalytic performance, chemical stability, and mechanical strength. In photocatalytic applications, carbon nitride materials can effectively absorb light energy and convert it into chemical energy for water splitting to produce hydrogen, carbon dioxide reduction, and degradation of organic pollutants. In addition, in the fields of electronics and optoelectronics, carbon nitride materials are also studied as new semiconductor materials due to their special bandgap structure. With the continuous growth of these application demands, higher requirements are put forward for the preparation and performance optimization of carbon nitride materials. Among them, the microstructure and particle size of the materials directly affect their performance. Therefore, it is usually necessary to grind the carbon nitride materials before further use.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] Referring to Figures 1 - 3 , an embodiment provided by the present invention: a grinding device for a carbon nitride material, including a bracket 1, a grinding chamber 2 is fixedly connected to the outer wall of the bracket 1, a feed hopper 3 is fixedly connected to the outer wall of the grinding chamber 2, a discharge hopper 4 is fixedly connected to the outer wall of the bracket 1, a first motor 5 is fixedly connected to the outer wall of the bracket 1, a main runner 6 is fixedly connected to the output end of the first motor 5, a first belt 7 is arranged on the outer wall of the main runner 6, a secondary runner 8 is arranged on the outer wall of the first belt 7, a first rotating shaft 9 is rotatably connected inside the secondary runner 8, a rolling drum 10 is fixedly connected to the outer wall of the first rotating shaft 9, a first driving wheel 11 is fixedly connected to the outer wall of the first rotating shaft 9, a second belt 12 is arranged on the outer wall of the first driving wheel 11, a second driving wheel 13 is arranged on the outer wall of the second belt 12, a second rotating shaft 14 is fixedly connected inside the second driving wheel 13, a second grinding rod 22 is fixedly connected to the outer wall of the second rotating shaft 14, a third driving wheel 15 is fixedly connected to the outer wall of the second rotating shaft 14, a third belt 16 is arranged on the outer wall of the third driving wheel 15, a fourth driving wheel 17 is arranged on the outer wall of the third belt 16, and a grinding assembly is arranged inside the fourth driving wheel 17 for initially grinding the material; the grinding assembly includes symmetrically arranged connecting shafts 18 on the left and right, the outer wall of the left connecting shaft 18 is fixedly connected inside the fourth driving wheel 17, a first grinding rod 19 is rotatably connected to the outer wall of the connecting shaft 18, a grinding plate 20 is fixedly connected to the outer wall of the connecting shaft 18, a gear 21 is fixedly connected to the outer wall of the connecting shaft 18, and the two gears 21 are meshed with each other; the main runner 6 and the secondary runner 8 are connected by the first belt 7, the first driving wheel 11 and the second driving wheel 13 are connected by the second belt 12, and the third driving wheel 15 and the fourth driving wheel 17 are connected by the third belt 16; the outer wall of the second rotating shaft 14 is rotatably connected inside the grinding chamber 2, and the outer wall of the rolling drum 10 is rotatably connected inside the grinding chamber 2;

[0024] Specifically, when it is necessary to fully grind the material, first, the main rotating wheel 6 is driven to rotate by the first motor 5. The main rotating wheel 6 drives the auxiliary rotating wheel 8 to rotate through the first belt 7. The auxiliary rotating wheel 8 further drives the first rotating shaft 9 and the material rolling cylinder 10. The rotation of the material rolling cylinder 10 is responsible for discharging the ground material inside the grinding chamber 2 to ensure the smooth discharge of the material. Driven by the first rotating shaft 9, the first driving wheel 11 starts to rotate. Through the second belt 12, the first driving wheel 11 drives the second driving wheel 13 to rotate. The second driving wheel 13 then drives the second rotating shaft 14 and the second grinding rod 22, so that the second grinding rod 22 performs secondary grinding on the material. The grinding at this stage helps to further refine the material and improve the grinding quality. At the same time, the second rotating shaft 14 also drives the third driving wheel 15 to rotate. The third driving wheel 15 drives the fourth driving wheel 17 through the third belt 16. The fourth driving wheel 17 then drives the connecting shaft 18 to rotate. The connecting shaft 18 cooperates with the gear 21 to drive the two grinding plates 20 to rotate in opposite directions. The opposite rotation of the grinding plates 20 performs preliminary grinding on the material. This multi-stage grinding ensures that the material undergoes grinding in multiple stages, not only improving the grinding effect, but also enhancing the overall practicality and working efficiency of the equipment.

[0025] Refer to Figure 2 and Figure 4 As shown in FIGS. 2 and 3, a first screen 23 is fixedly connected inside the grinding chamber 2, and the first screen 23 is in contact with the second grinding rod 22; a fixed frame 24 is slidably connected inside the grinding chamber 2, and a second screen 25 is fixedly connected inside the fixed frame 24; snap rings 26 are fixedly connected to the outer wall of the fixed frame 24 and the inner part of the grinding chamber 2. A limiting spring 27 is arranged inside the grinding chamber 2, and both ends of the limiting spring 27 are fixedly connected to the outer wall of the snap ring 26; a second motor 28 is fixedly connected to the outer wall of the grinding chamber 2, the output end of the second motor 28 is fixedly connected with a rotating rod 29, and a roller sleeve 30 is rotatably connected to the outer wall of the rotating rod 29;

[0026] Specifically, when it is necessary to screen the material, the motor two 28 drives the rotating rod 29 to rotate. The rotating rod 29 intermittently pushes the second sieve 25 through the roller sleeve 30, causing the second sieve 25 to shake inside the grinding chamber 2. The shaking of the second sieve 25 is achieved by the telescopic action of the limiting spring 27. The limiting spring 27 allows the second sieve 25 to move freely within a certain range, which can effectively shake off the material accumulated on the surface of the second sieve 25, completing the preliminary screening process. After the preliminary screening, the first sieve 23 and the second grinding rod 22 work in coordination. The second grinding rod 22 not only continues to finely grind the material but also performs screening. The rotation of the second grinding rod 22 and the cooperation of the first sieve 23 can more finely classify the ground material according to particle size. During the grinding process, the material continuously passes through the first sieve 23, screening out particles of different particle sizes, leaving the larger particles on the surface of the first sieve 23, while the smaller particles flow out through the first sieve 23, thus achieving the effect of multi-step screening. This ensures that the ground material can be effectively separated, enabling each particle size level of the material to be properly processed. This not only improves the quality of the material but also enhances the overall efficiency of the equipment.

[0027] Working principle: When it is necessary to fully grind the material, the motor one 5 drives the main runner 6 to rotate, enabling the main runner 6 to drive the auxiliary runner 8 to rotate through the first belt 7, and then driving the first rotating shaft 9 and the rolling drum 10 to rotate together, so that the rolling drum 10 can unload the material that has been ground inside the grinding chamber 2. Then, the first rotating shaft 9 drives the first driving wheel 11 to rotate, enabling the first driving wheel 11 to drive the second driving wheel 13 to rotate in cooperation with the second belt 12, and then driving the second rotating shaft 14 and the second grinding rod 22 to rotate, so that the second grinding rod 22 can grind the material for the second time. Then, the second rotating shaft 14 drives the third driving wheel 15 to rotate, enabling the third driving wheel 15 to drive the fourth driving wheel 17 and the connecting shaft 18 to rotate in cooperation with the third belt 16, so that the connecting shaft 18 can drive the two grinding plates 20 to rotate in opposite directions in cooperation with the gear 21, thereby preliminarily grinding the material, thus achieving the effect of multi-stage grinding of the material, ensuring the grinding effect of the device, improving the practicality and working efficiency of the device. When it is necessary to screen the material, the motor two 28 drives the rotating rod 29 to rotate, enabling the rotating rod 29 to intermittently push the second sieve 25 through the roller sleeve 30, causing the second sieve 25 to shake inside the grinding chamber 2 due to the telescopic action of the limiting spring 27, and then the material on the surface of the second sieve 25 can be shaken off, thereby performing preliminary screening. Then, the first sieve 23 can cooperate with the second grinding rod 22 to grind and screen the material at the same time, thus achieving the effect of multi-step screening of the ground material and improving the grinding quality of the device.

[0028] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features.
