[0030] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0031] In this application, terms such as "upper," "inner," "outer," and "middle" indicate positions or locations based on those shown in the accompanying drawings. These terms are intended to better describe this application and its embodiments and are not intended to limit the devices, elements, or components indicated to specific positions, or to their construction or operation in a specific position.

[0032] like Figure 1-4 As shown, a reactor for efficient graphite mixing and stirring comprises a reactor body 3 and a lid 1 flange-connected to the reactor body 3. The reactor body 3 comprises an outer shell 4, an annular oil heating layer 5, and a heat-conducting inner liner 6. The annular oil heating layer 5 is connected to an oil temperature controller 8 via an oil conduit 7. The annular oil heating layer 5 is connected to the oil temperature controller 8 via the oil conduit 7, providing a stable heating environment for the heat-conducting inner liner 6, ensuring the desired temperature during the graphite mixing process. A platform 2 is connected to the lower end of the reactor body 3. This ensures stable operation of the reactor and reduces the impact of external environmental factors on the reactor's operation.

[0033] like Figure 4 and Figure 5As shown, the central axis position of the cover body 1 is rotatably connected to a rotating rod 9, and the rotating rod 9 is connected to the driving shaft of the reduction motor 10. The reduction motor 10 is connected to the cover body 1, and a plurality of stirring paddles 11 are evenly connected to the bottom of the rotating rod 9. The stirring paddles 11 are in contact with the bottom and side walls of the heat-conducting liner 6. The stirring paddles 11 are tilted, and one end of the stirring paddle 11 that is in contact with the side wall of the heat-conducting liner 6 is connected to a scraper 12, and the height of the scraper 12 is higher than the stirring paddle 11; then the central material of the heat-conducting liner 6 moves downward, the bottom material of the heat-conducting liner 6 moves centrifugally, and the edge material of the heat-conducting liner 6 moves upward, so that the temperature of the material is uniform, and the material can move back and forth, and the stirring paddle 11 is in contact with the bottom and side walls of the heat-conducting liner 6, scraping the material from the bottom and side walls of the liner, ensuring that the material can be stirred in all directions, avoiding material accumulation.

[0034] like Figure 5As shown, the cover 1 is also connected to a feeding channel 13, an exhaust port 15, a pressure sensor 17, and a temperature sensor 18. The pressure sensor 17 and the temperature sensor 18 can monitor the pressure and temperature changes in the reactor in real time to ensure that the reactor operates within a safe and stable range. A rotary drum 19 is rotatably connected to the feeding channel 13. The rotary drum 19 has a feed port 22 corresponding to the feeding channel 13. The rotary drum 19 is connected to the drive shaft of a first drive motor 23, which is fixedly connected to the feeding channel 13. A propeller 20 is rotatably connected to the rotary drum 19, which is connected to the drive shaft of a second drive motor 21, which is fixedly connected to the rotary drum 19. The material is then placed in the feeding channel 13. The first drive motor 23 drives the rotary drum 19 to rotate in the feeding channel 13, so that the feed port 22 of the rotary drum 19 faces upward, and the material enters the rotary drum 19 through the feed port 22. At the same time, the second drive motor 21 drives the propeller 20 to rotate in the rotary drum 19 to ensure that the material is evenly distributed in the rotary drum 19. The first drive motor 23 drives the rotary drum 19 to rotate in the feeding channel 13, so that the feed port 22 of the rotary drum 19 faces downward. With the propeller 20 rotating in the rotary drum 19, the material in the rotary drum 19 falls into the heat-conducting inner liner 6, achieving continuous, uniform, and quantitative feeding of the material, improving the feeding efficiency, and reducing the problem of material blockage and dust during the feeding process. The end side wall of the feeding channel 13 is rotatably connected to the discharge plate 14, which is arranged above the rotary drum 19. The remaining material can be recycled by rotating the discharge plate 14. The exhaust port 15 is connected to a gas-solid separator 16. During the mixing process, generated gases are discharged through the exhaust port 15, maintaining pressure balance within the reactor. The gas-solid separator 16, connected to the exhaust port 15, separates solid particles from the gas and discharges the gas, preventing contamination by solid particles. The cover 1, outer shell 4, and heat-conducting liner 6 are all made of stainless steel. The corrosion resistance and high temperature resistance of stainless steel enhance the stability of the reactor and prevent corrosion and contamination of the reactor by materials.

[0035] The bottom of the thermal liner 6 is provided with a discharge port 24, to which a discharge pipe 25 is connected, and a drop pipe 27 is provided at the lower end of the discharge pipe 25, and a plug 28 is slidably connected in the discharge pipe 25. The end of the discharge pipe 25 is connected to a driving cylinder 29, and the piston rod of the driving cylinder 29 is connected to the plug 28. When the mixing reaction is completed and the material needs to be discharged, the driving cylinder 29 is started, and the piston rod of the driving cylinder 29 pushes the plug 28 to release the blockage of the discharge port 24. At the same time, the reduction motor 10 drives the rotating rod 9 and the stirring paddle 11 to rotate, and then the material in the thermal liner 6 is discharged through the discharge port 24, the discharge pipe 25 and the drop pipe 27, thereby avoiding the blockage of the material. The upper end of the discharge pipe 25 is provided with a blowing port 26, and the position of the blowing port 26 corresponds to that of the discharge pipe 25. Furthermore, when there is residual material during the discharge process, inert gas is blown into the lower feeding pipe 25 through the blowing port 26 to help the material to be discharged smoothly.

[0036] The working process of this utility model is:

[0037] First, the annular oil heating layer 5 is connected to the oil temperature machine 8 through the oil pipe 7, providing a stable heating environment for the heat-conducting inner tank 6, ensuring that the graphite mixing process is under the required temperature conditions.

[0038] Then the material is placed in the feeding channel 13, and the first drive motor 23 drives the rotary drum 19 to rotate in the feeding channel 13 so that the feed port 22 of the rotary drum 19 faces upward, and then the material enters the rotary drum 19 through the feed port 22. At the same time, the second drive motor 21 drives the propeller 20 to rotate in the rotary drum 19 to ensure that the material is evenly arranged in the rotary drum 19. Then the first drive motor 23 drives the rotary drum 19 to rotate in the feeding channel 13 so that the feed port 22 of the rotary drum 19 faces downward, and the propeller 20 rotates in the rotary drum 19. The material in the rotary drum 19 falls into the heat-conducting liner 6, and then the first drive motor 23 drives the rotary drum 19 so that the feed port 22 faces upward. Then the reduction motor 10 drives the rotating rod 9 and the stirring paddle 11 to rotate. The stirring paddle 11 is in contact with the bottom and side wall of the heat-conducting inner liner 6. The stirring paddle 11 is tilted. One end of the stirring paddle 11 that is in contact with the side wall of the heat-conducting inner liner 6 is connected to a scraper 12. The height of the scraper 12 is higher than the stirring paddle 11, so that the central material of the heat-conducting inner liner 6 moves downward, the bottom material of the heat-conducting inner liner 6 moves centrifugally, and the edge material of the heat-conducting inner liner 6 moves upward, so that the material is heated evenly and the material can move back and forth. During the stirring and mixing process, the generated gas is discharged through the exhaust port 15. The gas-solid separator 16 connected to the exhaust port 15 separates the solid particles in the gas and discharges the gas.

[0039] When the mixing reaction is completed and the material needs to be discharged, the driving cylinder 29 is started, and the piston rod of the driving cylinder 29 pushes the plug 28 to release the blockage of the discharge port 24. At the same time, the reduction motor 10 drives the rotating rod 9 and the stirring paddle 11 to rotate, and then the material in the heat-conducting liner 6 is discharged through the discharge port 24, the discharge pipe 25 and the drop pipe 27. If there is any residual material during the discharge process, inert gas is blown into the discharge pipe 25 through the blowing port 26 to help the material be discharged smoothly.
