[0024] [First embodiment] Reference Figure 1-10 As shown, a high-temperature carbonization furnace for preparing carbon nanotubes disclosed in the first embodiment of the present invention is shown. Figure 1 As shown, it includes a furnace body 1, a heater 2 is arranged on one side of the furnace body 1, a conduit 3 is arranged on the top of the furnace body 1, a furnace door 4 is arranged on the front side of the furnace body 1, and the furnace door 4 is connected to the furnace body 1 through a hinge. A storage device 5 is arranged inside the furnace body 1 for storing and neatly arranging the raw materials put into the furnace body 1. First, the raw materials for preparing carbon nanotubes are put into the storage device 5. Under the action of the storage device 5, the put raw materials can be neatly arranged. At this time, the furnace door 4 is closed and the heater 2 is started. The heater 2 provides heat to the inside of the furnace body 1 under the driving action of an external power source. When the temperature inside the furnace body 1 reaches a specified value, the raw materials are pyrolyzed in the furnace body 1 to generate gas and carbonaceous materials. Then the gas is discharged into an external vacuum device through the conduit 3 for storage, thereby achieving high-temperature carbonization treatment of the raw materials. At the same time, the regular raw materials can be taken out one by one later, reducing the damage caused by the disorderly arrangement of the raw materials when taking the materials.

[0025] Reference Figure 2-8As shown, the present embodiment discloses a storage device 5 including a circular tube 51 and an annular plate 56, a cooling device 6 is arranged on one side of the annular plate 56, the circular tube 51 is fixedly connected to the inner wall of the furnace body 1, the annular plate 56 is sleeved on the outer circumference of the circular tube 51 and is rotatably connected thereto, the annular plate is located inside the furnace body 1, a rectangular hole 52 is provided on one side of the circular tube 51, a U-shaped cylinder 57 is fixedly connected to one side of the annular plate 56, the U-shaped cylinder 57 is adapted to the rectangular hole 52, a plurality of air holes 58 are provided inside the U-shaped cylinder 57, a limiting ring 59 is fixedly connected to the side of the U-shaped cylinder 57 away from the annular plate 56, a baffle 510 is slidably connected to the inner wall of the limiting ring 59, the baffle 510 is slidably connected to the inside of the U-shaped cylinder 57, and a fixed connection is provided on one side of the annular plate 56. A first gear ring 514 is connected, a motor 53 is fixedly connected to one side of the furnace body 1, an output end of the motor 53 is fixedly connected to a circular shaft 54, the circular shaft 54 ​​is rotatably connected to the inner wall of the furnace body 1, an end of the circular shaft 54 ​​away from the motor 53 is fixedly connected to a first gear 55, the first gear 55 is located inside the furnace body 1, the first gear 55 is correspondingly meshed with the first gear ring 514, a circular hole block 511 is slidably connected to the inside of the annular plate 56, a first spring 513 is fixedly connected to one side of the circular hole block 511, the other end of the first spring 513 is fixedly connected to the first gear ring 514, a pressure plate 512 is fixedly connected to one side of the circular hole block 511, the pressure plate 512 is located inside the U-shaped cylinder 57, and the pressure plate 512 is slidably connected to the inside of the U-shaped cylinder 57. By setting up the storage device 5, first move the baffle 510 so that the baffle 510 slides along the inside of the limiting ring 59. When the baffle 510 moves to a position completely inserted into the inside of the limiting ring 59, the baffle 510 completely closes the opening position of the U-shaped cylinder 57 on one side close to the circular tube 51. At this time, slide the pressure plate 512 open and stack the raw materials in the U-shaped cylinder 57 in sequence. The raw materials are neatly stored in the U-shaped cylinder 57. Then slide and close the pressure plate 512 to squeeze the raw materials inside the U-shaped cylinder 57, thereby completing the neat stacking of the raw materials.

[0026] After the raw material is carbonized inside the furnace body 1, the motor 53 is started, so that the motor 53 drives the first gear 55 to rotate through the circular shaft 54, and the first gear 55 drives the first gear ring 514 meshed with it to rotate, so that the first gear ring 514 drives the annular plate 56 to rotate along the outer circumference of the circular tube 51, and the U-shaped cylinder 57 is driven to rotate through the annular plate 56. When the U-shaped cylinder 57 rotates to a position where the inner wall coincides with the inner wall of the rectangular hole 52, the baffle 510 is moved out of the limiting ring 59 and the inside of the U-shaped cylinder 57, so that the baffle 510 releases the interception limit of the raw material inside the U-shaped cylinder 57. At this time, the reaction force of the first spring 513 The first spring 513 pulls the circular hole block 511 and the pressure plate 512 to move toward the circular tube 51, so that the pressure plate 512 squeezes the raw material inside the U-shaped cylinder 57. At this time, the raw material inside the U-shaped cylinder 57 is pressed into the circular tube 51 through the rectangular hole 52 by the pressure plate 512, thereby facilitating the removal of the raw materials pressed into the circular tube 51 one by one, reducing the risk of raw materials being broken or damaged when being taken out due to the large resistance between the raw materials when personnel are taking them out, thereby improving the convenience of personnel taking materials and the production quality of raw materials.

[0027] Reference Figure 2-8 As shown, in the present embodiment, a positioning rod 515 is fixedly connected to one side of the first gear ring 514. The positioning rod 515 is passed through the interior of the circular hole block 511 and is slidably connected thereto. The positioning rod 515 is located inside the first spring 513. By setting the positioning rod 515, the positioning rod 515 can assist in limiting the circular hole block 511 and the pressure plate 512, thereby reducing unexpected shaking of the circular hole block 511 and the pressure plate 512 during use. At the same time, the positioning rod 515 is located inside the first spring 513 to provide auxiliary support to the interior thereof, thereby reducing the possibility of large bending and deformation of the first spring 513 during telescopic movement.

[0028] A collecting trough 516 is fixedly connected to the inside of the circular tube 51. The cross-section of the collecting trough 516 is semicircular. A discharge hole 518 is opened on one side of the collecting trough 516. A filter plate 517 is fixedly connected to the inside of the collecting trough 516. By arranging the collecting trough 516 and the filter plate 517, the raw materials falling from the rectangular hole 52 can be intercepted by the filter plate 517, so that small particles of carbon slag and carbon powder scattered when the raw materials fall can enter the collecting trough 516 through the filter plate 517 for collection and storage, while large particles of carbon slag and carbon powder cannot pass through the filter plate 517 and stay on the top of the filter plate 517, so that personnel can classify and collect carbon slag and carbon powder of different particle sizes and reuse them, thereby improving the utilization rate of resources.

[0029] Preferably, two connecting blocks 519 are symmetrically fixedly connected to one side of the collecting trough 516, and an elastic belt 520 is fixedly connected between the two connecting blocks 519. By setting the elastic belt 520, the elastic belt 520 can intercept the falling raw materials and have a certain buffering effect, thereby reducing the direct collision between the raw materials and the filter plate 517, causing the raw materials to break, and improving the discharge stability of the raw materials.

[0030] Reference Figure 2-8 As shown, the collection tank 516 in this embodiment is internally slidably connected with a scraper 521, and one side of the scraper 521 is fixedly connected with a pull rod 522, and the pull rod 522 slides with the collection tank 516. By setting the scraper 521, the scraper 521 can be driven to move by moving the pull rod 522, so that the scraper 521 moves along the inside of the collection tank 516 and pushes the carbon residue and carbon powder stored in the collection tank 516 out through the discharge hole 518, thereby further improving the efficiency and convenience of collecting carbon residue and carbon powder.

[0031] Reference Figure 6-10 As shown, the cooling device 6 in this embodiment includes a hollow tube 62, which is rotatably connected to one side of the annular plate 56, and a second gear 61 is fixedly connected to one side of the hollow tube 62. A second gear ring 611 is fixedly connected to the inner wall of the furnace body 1, and the second gear 61 is meshed with the second gear ring 611. A fan 63 is provided on one side of the hollow tube 62, and a plurality of air ducts 65 are fixedly connected to one side of the hollow tube 62. The air ducts 65 correspond to the positions of the air holes 58. The hollow tube 62 is located on one side of the U-shaped cylinder 57. By setting the cooling device 6, when the raw material is carbonized, the motor 53 is started, so that the motor 53 drives the first gear 55 and the first gear ring 514 to rotate, and the first gear 63 is used to rotate the first gear 55 and the first gear ring 514. The ring 514 drives the annular plate 56 to rotate, so that the annular plate 56 drives the hollow tube 62 and the second gear 61 to move. Under the meshing action of the second gear 61 and the second gear ring 611, the second gear 61 rotates while following the rotation of the annular plate 56, so that the second gear 61 drives the hollow rod and the multiple air ducts 65 to rotate. At this time, the fan 63 is started, so that the fan 63 conveys wind force into the hollow tube 62, and the wind force is discharged through the multiple air ducts 65. The wind force assists in cooling the raw materials inside the U-shaped tube 57 through the air vents 58, thereby reducing the high temperature of the raw materials after carbonization, which may cause accidental scalding when manually taking the materials, and improving the safety when taking the materials.

[0032] Reference Figure 6-10As shown, this embodiment discloses that one end of the hollow tube 62 away from the second gear 61 is fixedly connected with a bearing 64, one side of the U-shaped cylinder 57 is fixedly connected with a support plate 610, and the outer ring of the bearing 64 is fixedly connected to the support plate 610. By arranging the bearing 64 and the support plate 610, the bearing 64 cooperates with the support plate 610 to provide auxiliary support for the side of the hollow tube 62 away from the second gear 61, thereby reducing the unexpected shaking of the side of the hollow tube 62 away from the second gear 61 during use. At the same time, the bearing 64 can increase the rotation efficiency and stability between the hollow tube 62 and the support plate 610.

[0033] Reference Figure 6-10 As shown, in the present embodiment, one side of the plurality of air ducts 65 is fixedly connected with a rotating frame 66, the inner sides of the plurality of rotating frames 66 are fixedly connected with a second spring 67, and the other side of the second spring 67 is fixedly connected with a cover plate 68, the cross-sectional area of ​​the cover plate 68 is larger than the cross-sectional area of ​​the pipe opening of the air duct 65. By providing the cover plate 68, when the fan 63 provides wind force to the hollow tube 62 and the inside of the air duct 65, the wind force is discharged through the air duct 65 and the cover plate 68 is pushed up, so that the cover plate 68 releases the seal with the outlet of the air duct 65. When the air duct 65 finishes discharging wind force, under the reaction force of the second spring 67, the second spring 67 drives the rotating frame 66 to move in a closed manner, and the cover plate 68 is driven by the rotating frame 66 to completely cover the air duct 65, thereby reducing the external carbon residue, carbon powder and dust from entering the air duct 65, causing the air duct 65 to be blocked, thereby improving the use efficiency of the air duct 65.

[0034] Furthermore, a rubber pad 69 is fixedly connected to one side of each of the multiple cover plates 68. The surface of the rubber pad 69 is rectangular, and the cross-sectional area of ​​the rubber pad 69 is larger than the cross-sectional area of ​​the pipe opening of the air duct 65. By providing the rubber pad 69, the rubber pad 69 can fill and seal the gap between the cover plate 68 and the air duct 65, thereby reducing the possibility of external dust, carbon residue and carbon powder entering the interior of the air duct 65 through the gap.

[0035] The working process of this embodiment is: First, move the baffle 510 so that the baffle 510 slides along the inside of the limiting ring 59. When the baffle 510 moves to a position where it is completely inserted into the inside of the limiting ring 59, the baffle 510 completely closes the opening position of the U-shaped cylinder 57 close to the round tube 51. At this time, slide the pressing plate 512 open and stack the raw materials in the U-shaped cylinder 57 in sequence, so that the raw materials are neatly stored in the U-shaped cylinder 57. The pressing plate 512 squeezes the raw materials in the U-shaped cylinder 57, thereby completing the neat stacking of the raw materials. At this time, close the furnace door 4 and start the heater 2, so that the heater 2 provides heat to the inside of the furnace body 1 under the driving action of the external power source. When the temperature inside the furnace body 1 reaches a specified value, the raw materials are pyrolyzed in the furnace body 1 to generate gas and carbonaceous materials. Then, the gas is discharged into the external vacuum equipment through the conduit 3 for storage, thereby achieving high-temperature carbonization treatment of the raw materials. After the raw material is carbonized inside the furnace body 1, the motor 53 is started. The motor 53 outputs power to drive the first gear 55 to rotate through the circular shaft 54, and the first gear ring 514 is driven to rotate through the first gear 55, so that the first gear ring 514 drives the annular plate 56 to rotate along the outer circumference of the circular tube 51, and the U-shaped tube 57 is driven to rotate through the annular plate 56. At the same time, the annular plate 56 drives the hollow tube 62 and the second gear 61 to move. Under the meshing action of the second gear 61 and the second gear ring 611, the second gear 61 rotates in the process of following the rotation of the annular plate 56, so that the second gear 61 drives the hollow rod and the multiple air ducts 65 to rotate. At this time, the fan 63 is started, so that the fan 63 transmits wind to the inside of the hollow tube 62, and the wind is discharged through the multiple air ducts 65. The wind passes through the air vents 58 to assist in cooling the raw material inside the U-shaped tube 57, thereby completing the rapid cooling of the raw material after carbonization. When the U-shaped cylinder 57 rotates to the position where the inner wall coincides with the inner wall of the rectangular hole 52, the baffle 510 is moved out of the limiting ring 59 and the inside of the U-shaped cylinder 57, so that the baffle 510 releases the interception and limiting of the raw material inside the U-shaped cylinder 57. At this time, under the reaction force of the first spring 513, the circular hole block 511 and the pressing plate 512 are pulled by the first spring 513 to move toward the direction of the circular tube 51, so that the pressing plate 512 squeezes the raw material inside the U-shaped cylinder 57, so that the raw material inside the U-shaped cylinder 57 is pressed into the inside of the circular tube 51 through the rectangular hole 52 by the pressing plate 512, so that the raw material falls on the elastic band 520 and is released by the elastic band 520. The belt 520 intercepts the falling raw materials and has a certain buffering effect, reducing the possibility of direct collision and damage between the raw materials and the filter plate 517, so that the small particles of carbon slag and carbon powder scattered when the raw materials fall can pass through the filter plate 517 into the collection tank 516 for collection and storage, while the large particles of carbon slag and carbon powder cannot pass through the filter plate 517 and stay on the top of the filter plate 517, so that personnel can classify and collect carbon slag and carbon powder of different particle sizes and reuse them, thereby improving the utilization rate of resources. At this time, the raw materials pressed into the circular tube 51 can be taken out one by one, thereby completing the safe and fast removal of the raw materials.
