Abstract
Description
Technical Field
[0001] This utility model relates to the field of rapid cooling of green raw materials of high-strength graphite, and more specifically, to a rapid cooling device for green raw materials of high-strength graphite. Background Technology
[0002] Rapid cooling of high-strength graphite green blanks refers to the process of rapidly reducing the temperature of pre-formed graphite green blanks that have not yet undergone high-temperature graphitization treatment during the preparation of graphite green blanks using a special cooling method. Rapid cooling helps to fix their internal structure, such as maintaining the stability of the pore structure. If the cooling is too slow, structural deformation may occur due to factors such as thermal stress, affecting the strength of the final graphite product. For example, in some graphite green blanks impregnated with additives, rapid cooling can prevent excessive migration and segregation of the additives, thereby ensuring that the additives can play a uniform role in subsequent processing and improve the strength of the graphite.
[0003] In existing technologies, during the green body preparation process, natural cooling relies entirely on heat exchange with the surrounding environment to reduce the green body temperature. The cooling rate is slow, which greatly prolongs the production cycle and reduces production efficiency for large-scale production. During natural cooling, the heat exchange conditions between different parts of the green body and the surrounding environment are different, which can easily lead to uneven cooling of the green body and generate thermal stress, which in turn causes defects such as cracks, thus affecting the strength and quality of the final graphite product. Therefore, we propose a rapid cooling device for high-strength graphite green body raw materials to solve the above-mentioned problems. Utility Model Content

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0026] Example 1:
[0027] Please see Figure 1 - Figure 6A rapid cooling device for high-strength graphite green raw materials includes a top plate 1, with side plates A2 and B3 fixedly connected to both sides of the top plate 1 respectively. A motor 4 is fixedly connected to the surface of side plate A2, and a rotating shaft 5 is fixedly connected to the output end of the motor 4. The rotating shaft 5 passes through the side plate A2, and two drive wheels 6 are fixedly connected to the arc surface of the rotating shaft 5. An extension arm 7 is fixedly connected to the side of side plate A2 and side plate B3 that are far apart from each other. A threaded rod 8 is threaded through the surface of the extension arm 7. A limit plate 9 is rotatably connected to the end of the two threaded rods 8 that are close to each other. A limit arm 10 is fixedly connected to the surface of side plate A2 and side plate B3. A connecting plate 11 is fixedly connected to the surface of the limit arm 10. Two driven wheels 12 are rotatably connected to the surface of the connecting plate 11. A cooling fan 13 is fixedly connected to the surface of the driven wheels 12. A transmission belt 14 is sleeved on the surface of the two driven wheels 12 and the drive wheel 6. Two rotating rods are fixedly connected to the side of side plate A2 and side plate B3 that are close to each other. Several shielding strips 15 are rotatably connected to the arc surface of the rotating rods. Two round rods 16 are fixedly connected to the side of side plate A2 and side plate B3 that are close to each other. Two heat-concentrating tubes 17 are fixedly connected to the side of side plate B3 that is away from side plate A2. Two guide rods 18 slide through the surface of the extension arm 7, and both guide rods 18 are fixedly connected to the surface of the limiting plate 9. A filter screen 19 is fixedly connected to the surface of side plate B3.
[0028] Working principle: When rapid cooling of high-strength graphite green material is required, the top plate 1, along with side plates A2 and B3, is first placed on the surface of the conveyor belt. Side plates A2 and B3 will respectively adhere to the two sides of the conveyor belt. Then, the threaded rod 8 is rotated. The rotation of the threaded rod 8 will cause it to move within the extension arm 7 via the thread. The movement of the threaded rod 8 will cause the limiting plate 9 to move closer to the conveyor belt. The movement of the limiting plate 9 will cause the guide rod 18 to slide within the extension arm 7. The guide rod 18 restricts the movement path of the limiting plate 9, thereby preventing the limiting plate 9 from rotating during movement. When the limiting plate 9 moves to the appropriate position... After positioning, the two limiting plates 9 will simultaneously press against the surface of the conveyor belt, thereby limiting side plates A2 and B3 to the surface of the conveyor belt. Then, the exhaust pipes are connected to the two heat-concentrating pipes 17 respectively. Then, the conveyor belt is started, and the conveyor belt will transport the high-strength graphite green material to a position close to the side plates A2 and B3. After the high-strength graphite green material moves to the appropriate position, it will press against the blocking strip 15. The blocking strip 15 will rotate on the surface of the rotating rod with the force of the high-strength graphite green material. When the blocking strip 15 rotates to the appropriate position, the high-strength graphite green material can pass through the blocking strip 15. 5. When the position between the conveyor belt and side plate A2 and side plate B3 is reached, the blocking strip 15 will rotate back to its original position due to inertia. The blocking strip 15 will then adhere to the surface of the round rod 16, limiting the rotation angle of the blocking strip 15 and preventing it from jamming due to excessive reverse rotation. Motor 4 is then started. The rotation of motor 4 drives the rotating shaft 5 to rotate, which in turn drives the drive wheel 6 to rotate. The drive wheel 6, through the conveyor belt, drives the driven wheel 12 to rotate, which in turn drives the cooling fan 13 to rotate. The cooling fan 13 on side plate A2 will draw external air into side plate A2 and... In the area within side plate B3, the high-strength graphite green material on the conveyor belt moves to the middle position between side plates A2 and B3. Air is blown towards the high-strength graphite green material to cool it down. At this time, the cooling fan 13 on side plate B3 blows the air out of side plates A2 and B3. The filter 19 on side plate B3 filters the blown air to prevent debris of the high-strength graphite green material from entering and being discharged with the air. The blown air then enters the exhaust pipe from the heat-collecting pipe 17 and is discharged to prevent hot air from being discharged randomly in the workshop.
