[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-Figure 4A high-purity graphite preparation device comprises a box 1, a plurality of heaters 14 are fixedly mounted on the inner wall of the box 1, a vertical pipe 2 is vertically fixedly mounted in the box 1 through a support frame 15, a disc 3 is fixedly mounted on the upper end of the vertical pipe 2, and a circular hole connected to the vertical pipe 2 is opened on the surface of the disc 3;

[0022] A rotating shaft 4 is vertically inserted into the vertical tube 2, and one end of the rotating shaft 4 passes through the box body 1. A driving motor 5 is fixedly installed on the upper end of the box body 1. The output shaft of the driving motor 5 is fixedly connected to the rotating shaft 4. A spiral leaf 6 is fixedly sleeved on the rotating shaft 4, and both ends of the spiral leaf 6 extend out of the vertical tube 2.

[0023] When drying graphite, first add graphite into the box 1, then start the driving motor 5, drive the rotating shaft 4 to rotate through the output shaft of the driving motor 5, and then drive the spiral blade 6 to rotate in the vertical tube 2 through the rotating shaft 4. During the rotation of the spiral blade 6, the graphite at the bottom of the box 1 will be transported to the vertical tube 2, and then continuously move upward along the vertical tube 2 until it is transported to the disc 3. As the graphite on the disc 3 continues to increase, the graphite on the disc 3 will fall from the disc 3 to the bottom of the box 1. In the process of graphite falling from the disc 3, the heater 14 installed inside the box 1 can effectively heat it. The spiral blade 6 can continuously drive the graphite at the bottom of the box 1 to move to the upper end of the vertical tube 2, and then fall from the upper end, so as to avoid the graphite from piling up during drying, and make the graphite flow between multiple heaters 14, thereby ensuring the comprehensive drying of the high-purity graphite and improving the drying effect of the high-purity graphite.

[0024] A plurality of support rods 12 are fixedly installed at the bottom of the box body 1. A discharge port is opened at the bottom of the box body 1. A discharge pipe 13 is fixedly installed in the discharge port. A valve is installed in the discharge pipe 13. The dried graphite can be taken out of the box body 1 through the universal discharge pipe 13 by opening the valve.

[0025] A guide plate 7 is fixedly installed inside the box body 1. A conical groove is provided on the surface of the guide plate 7. A through hole connected to the discharge port is provided on the inner wall of the conical groove. The spiral blade 6 is located at the center of the guide plate 7. The graphite dropped from the disc 3 will fall into the conical groove. The guide plate 7 gathers the graphite at the bottom of the box body 1, thereby facilitating the spiral blade 6 to transport the graphite to the vertical pipe 2.

[0026] An annular ring 8 is fixedly mounted on the surface of the disc 3, and a plurality of rectangular holes are opened on the surface of the ring 8. A plurality of arc-shaped scraping rods 9 are arranged above the disc 3. A transmission assembly for driving the plurality of scraping rods 9 to rotate simultaneously is provided on the disc 3. The transmission assembly comprises a rotating ring 10 rotatably mounted on the disc 3 and a U-shaped connecting rod 11 fixedly mounted on the rotating ring 10. The plurality of scraping rods 9 are fixedly mounted on the rotating ring 10, and the connecting rod 11 is fixedly sleeved on the rotating shaft 4.

[0027] While the rotating shaft 4 drives the spiral blade 6 to rotate, it drives the rotating ring 10 to rotate through the connecting rod 11, and then drives multiple scraper rods 9 to rotate on the disc 3 through the rotating ring 10. Under the arc shape of the scraper rod 9, the graphite on the disc 3 can be driven to move around continuously, so that it passes through the rectangular hole opened in the ring 8 and falls from the disc 3.

[0028] The diameter of the spiral blade 6 is the same as the inner diameter of the vertical tube 2, and the side wall of the spiral blade 6 is in sliding contact with the inner wall of the vertical tube 2, ensuring that when the spiral blade 6 drives the graphite to move upward in the vertical tube 2, no graphite will pass through the gap between the spiral blade 6 and the inner wall of the vertical tube 2.

[0029] In the utility model, when drying graphite, firstly, graphite is added into the box body 1, and then the driving motor 5 is started, and the output shaft of the driving motor 5 drives the rotating shaft 4 to rotate, thereby driving the spiral blade 6 to rotate in the vertical tube 2. During the rotation of the spiral blade 6, the graphite at the bottom of the box body 1 is transported into the vertical tube 2, and then continuously moves upward along the vertical tube 2 to the disc 3. As the graphite on the disc 3 increases, the graphite will fall from the disc 3. The heater 14 installed inside the box body 1 can effectively heat it, avoid the graphite from piling up during drying, and make the graphite flow between multiple heaters 14, thereby ensuring the comprehensive drying of the high-purity graphite and improving the drying effect of the high-purity graphite.

[0030] In general, the technical problem is that the graphite to be dried is in a piled state. During drying, the graphite inside cannot be fully dried, which makes it easy for the high-purity graphite to be not dried completely, thereby affecting the drying effect of the high-purity graphite. A technical solution is adopted: through the cooperation of the vertical tube 2, the disc 3, the rotating shaft 4, the driving motor 5 and the spiral blade 6, the graphite can be driven to move continuously from top to bottom in the box 1; because the implementation process of the technical solution is: add graphite into the box 1, then start the driving motor 5, and drive the rotating shaft 4 to rotate through the output shaft of the driving motor 5, thereby driving the spiral blade 6. The spiral blade 6 rotates in the vertical tube 2. During the rotation, the spiral blade 6 will transport the graphite at the bottom of the box 1 into the vertical tube 2, and then continuously move upward along the vertical tube 2 to the disc 3. As the graphite on the disc 3 continues to increase, the graphite will fall from the disc 3, and the heater 14 installed inside the box 1 can effectively heat it; therefore, the technical problem can definitely be solved, and the technical effect achieved is: avoiding the graphite from piling up during drying, allowing the graphite to flow between multiple heaters 14, thereby ensuring the comprehensive drying of the high-purity graphite and improving the drying effect of the high-purity graphite.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
