Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. In addition, terms such as "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0030] All electrical components appearing in this article are electrically connected to an external main controller and 220V mains power, and the main controller can be a conventional known device such as a computer for control.

[0031] In the description of the embodiments of the present utility model, it should be noted that the orientation or positional relationship indicated by terms such as "inside", "outside", "above", etc. is based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product of the present utility model is usually placed during use.

[0032] As Figures 1 to 7 shown, a graphitization box furnace includes: a fixed box 1, the fixed box 1 is open on one side, a heat insulation layer 102, a reflection layer 103 and a heat-resistant layer 104 are sequentially arranged inside the fixed box 1, electrode blocks 101 are arranged outside the fixed box 1, and there are multiple electrode blocks 101; a sealing assembly 4, arranged outside the fixed box 1, for sealing the open end of the fixed box 1; a moving assembly 2, arranged outside the fixed box 1, for controlling the sealing assembly 4; a rotating assembly 3, arranged outside the fixed box 1, for pushing the sealing assembly 4 to fold. Specifically, during the graphitization process, the generated gas is blocked by the sealing assembly 4 to avoid air pollution caused by gas leakage during the graphitization process and ensure the stability during the graphitization process. During the graphitization process, the sealing assembly 4 is closed and opened through the cooperation of the moving assembly 2 and the rotating assembly 3, which is convenient for adding and taking materials inside the fixed box 1.

[0033] As Figures 1 to 7 shown, a plurality of grooves 105 are further arranged outside the fixed box 1, and the inside of the heat insulation layer 102 is hollow. Specifically, when the hollow heat insulation layer 102 is in use, it blocks the temperature inside the heat-resistant layer 104 to avoid the heat inside the heat-resistant layer 104 from being transferred outward during use. At the same time, the heat is blocked by the hollow heat insulation layer 102 to avoid the fixed box 1 from having too high a temperature and causing the operator to be accidentally scalded when touching it during use.

[0034] As Figures 1 to 7As shown, the sealing assembly 4 includes a first cover plate 401 and a second cover plate 402. There are multiple first cover plates 401 and second cover plates 402, and adjacent first cover plate 401 and second cover plate 402 form a group. The first cover plate 401 and the second cover plate 402 are arranged at the opening end of the fixed box 1, and the first cover plate 401 is rotatably connected to the fixed box 1. The first cover plate 401 and the second cover plate 402 are strip-shaped. Connecting rings 405 are provided at both ends of the first cover plate 401, and fixed shafts 406 are provided at both ends of the second cover plate 402. The fixed shafts 406 are arranged inside the connecting rings 405 and rotate relative to the connecting rings 405. Fixed tubes 404 are provided on the outer sides of the second cover plates 402, and connecting grooves 403 are opened at both ends of the second cover plates 402. Specifically, the connecting rings 405 and the fixed shafts 406 are arranged at both ends of the first cover plate 401 and the second cover plate 402 to ensure that the first cover plate 401 and the second cover plate 402 fit tightly against the top of the fixed box 1, preventing the gas inside the fixed box 1 from escaping through the gaps between the first cover plate 401, the second cover plate 402 and the fixed box 1, and ensuring the sealing performance during use. The first cover plate 401 and the second cover plate 402 are folded in half through the cooperation of the connecting rings 405 and the fixed shafts 406, so as to reduce the space occupied by the first cover plate 401 and the second cover plate 402 during use when the first cover plate 401 and the second cover plate 402 are opened. The fixed tubes 404 are communicated with the fixed box 1 and are connected to the absorption mechanism, so as to collect the generated gas during the graphitization process, preventing the gas inside the fixed box 1 from accumulating and affecting the graphitization effect.

[0035] As Figures 1 to 7As shown in the figure, the moving component 2 includes fixing bars 201. There are multiple fixing bars 201, and the multiple fixing bars 201 are connected to the fixing box 1. The fixing bars 201 are strip-shaped, and the extending directions of both ends of the fixing bars 201 are perpendicular to the length extending direction of the first cover plate 401. Threaded rods 203 are provided inside the fixing bars 201, and sliding blocks 202 are provided outside the threaded rods 203. There are multiple sliding blocks 202. Connecting blocks 206 are provided on one side of the sliding blocks 202 relative to the first cover plate 401, and the connecting blocks 206 slide inside the connecting grooves 403. Second guiding grooves 207 and first guiding grooves 205 are respectively formed on one side of the sliding blocks 202 relative to the first cover plate 401. Guiding grooves 204 are formed on one side of the opposite surfaces of the first guiding grooves 205. Specifically, left-handed threads and right-handed threads are respectively provided at both ends of the threaded rod 203, so as to control the sliding blocks 202 to move towards each other or in opposite directions when the threaded rod 203 rotates. A motor is provided outside the fixing bar 201, and the output end of the motor is connected to the threaded rod 203. When it is necessary to open the first cover plate 401 and the second cover plate 402, first drive the sliding blocks 202 to move through the threaded rod 203. While the sliding blocks 202 are moving, push the second cover plate 402 through the rotating component 3, so as to guide the moving direction of the second cover plate 402. As the sliding blocks 202 continue to move, the sliding blocks 202 cooperate with the connecting blocks 206 to fold the first cover plate 401 and the second cover plate 402, which is convenient for the operator to take the materials inside the fixing box 1.

[0036] As Figures 1 to 7As shown in the figure, the rotating assembly 3 includes a connecting rod 301. There are multiple connecting rods 301, which are rotatably connected to the fixed box 1, and the connecting rods 301 correspond to the grooves 105. A rotating wheel 302 is provided at one end of each connecting rod 301. A guiding member 5 is further provided on the outer side of the connecting rod 301. There are multiple guiding members 5, and the guiding members 5 correspond to the connecting rods 301. Specifically, through the cooperation of the connecting groove 403 and the connecting block 206, during the process of opening the first cover plate 401 and the second cover plate 402, first, the sliding block 202 is used to push the connecting rod 301 to rotate. While the rotating connecting rod 301 pushes the second cover plate 402 upward, the second cover plate 402 is continuously pushed to open through the connecting block 206. A torsion spring rod is provided between the guiding rod 501 and the fixed box 1, so that after the connecting rod 301 rotates, it is reset by the torsion spring rod. Since the rotating wheel 302 is rotatably connected to the connecting rod 301, the frictional resistance during the process of the connecting rod 301 pushing the second cover plate 402 is reduced. When opening the first cover plate 401 and the second cover plate 402, the guiding member 5 slides along the first guiding groove 205. Since the first guiding groove 205 is inclined, while the guiding member 5 slides along the first guiding groove 205, it drives the connecting rod 301 to rotate around the torsion spring rod as the center. When it is necessary to use the first cover plate 401 and the second cover plate 402 to seal the fixed box 1, since the connecting rod 301 is reset under the drive of the torsion spring rod, the guiding member 5 slides inside the second guiding groove 207, avoiding interference between the connecting rod 301 and the second cover plate 402 during the process of sealing the fixed box 1 and ensuring the stability during use. During the movement of the sliding block 202, the connecting rod 301 is driven to rotate through the cooperation of the guiding member 5 and the first guiding groove 205. During the rotation of the connecting rod 301, the second cover plate 402 is pushed upward through the rotating wheel 302, guiding the moving direction of the second cover plate 402 and ensuring the stability during the opening process.

[0037] As Figures 1 to 7 shown, the guiding member 5 includes a guiding rod 501. A sliding disk 503 is provided inside the guiding rod 501. A spring 504 is provided between the sliding disk 503 and the connecting rod 301. An expansion rod 502 is provided on the outer side of the sliding disk 503, and the expansion rod 502 penetrates through one end of the guiding rod 501. Specifically, when the sliding block 202 moves in the reverse direction, the guiding rod 501 slides inside the first guiding groove 205 through the cooperation of the expansion rod 502 and the guiding groove 204. When the sliding blocks 202 move towards each other, since the outer side of the expansion rod 502 is inclined, the sliding block 202 gradually pushes the expansion rod 502 to slide into the guiding rod 501, causing the guiding rod 501 to slide inside the second guiding groove 207, avoiding interference between the expansion rod 502 and the sliding block 202 and ensuring the stability of the movement of the sliding block 202.

[0038] The foregoing has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments, and what is described in the above embodiments and the specification is only the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and all these changes and improvements fall within the scope of the present utility model claimed. The scope of protection required by the present utility model is defined by the appended claims and their equivalents.
