The various technical features in the utility model creation can be interactively combined under the premise of no mutual contradiction and conflict.

[0029] The utility model provides a kind of atmosphere roller drive mechanism of convenient cooling, it includes kiln main body 1, transmission shaft 4, transmission box 3 and rotary joint 5. Applied to the flow of material graphitization process, can effectively reduce the temperature of transmission mechanism, so that transmission mechanism is more stable and reliable in use process, guarantee the smooth progress of material graphitization.

[0030] Refer to Figures 1 to 5The kiln main body 1 is provided with a plurality of roller bars 11, and the kiln main body 1 is provided with roller bar boxes 2 on opposite sides. The two ends of the roller bar 11 extend into the roller bar boxes 2 on the two sides, and the transmission end of the roller bar 11 is connected with a driven bevel gear 111. The transmission box 3 is fixedly connected to the roller bar box 2 close to the transmission end of the roller bar 11, and the driven bevel gear 111 is located in the transmission box 3. The transmission shaft 4 is rotatably arranged in the transmission box 3, and a plurality of driving bevel gears 41 are sleeved and mounted on the transmission shaft 4. The driving bevel gears 41 correspond to the driven bevel gears 111 one by one and are engaged with each other. The transmission shaft 4 has a hollow structure (i.e. a hollow structure), and a rotary joint 5 is arranged at the end of the transmission shaft 4, and the rotary joint 5 is in communication with the internal cavity of the transmission shaft 4. The rotary joint 5 is used to be connected to the gas source. The rotary joint 5 is a mechanical component for connecting rotating parts and fixed pipelines to realize medium conveying and sealing, which includes a threaded connection part and a joint part. The threaded connection part is connected with the transmission shaft 4, and the joint part is connected with the gas source.

[0031] In the embodiment, the transmission end of the roller bar 11 is fixedly connected with a roller bar sleeve 112, the roller bar sleeve 112 is rotatably connected to the roller bar box 2, and extends into the transmission box 3. The transmission box 3 is fixedly connected with a sleeve mounting seat 32, the roller bar sleeve 112 is rotatably arranged in the sleeve mounting seat 32, and the driven bevel gear 111 is fixedly sleeved on the side of the roller bar sleeve 112 away from the roller bar 11.

[0032] In use, the transmission shaft 4 can be connected with a driving motor (not shown in the figure), the driving motor drives the transmission shaft 4 to rotate, the driving bevel gears 41 rotate synchronously with the transmission shaft 4, the driven bevel gears 111 engaged with the driving bevel gears 41 are driven to rotate, the roller bar sleeve 112 rotates with the driven bevel gears 111, and the roller bar 11 is driven to rotate. The rotary joint 5 connected with the gas source can introduce gas into the transmission shaft 4 to take away the heat transferred from the kiln main body 1 to the transmission shaft 4, thereby achieving the effect of air cooling of the transmission shaft 4, so as to reduce the temperature of the transmission mechanism. The driving motor drives the transmission shaft 4 to rotate, which is a technology familiar to those skilled in the art and can be realized. The specific connection structure and implementation principle can refer to the existing technology, and will not be described here.

[0033] Referring to Figures 2 to 4 Further, the transmission box 3 is fixedly connected with a limiting plate 31, the limiting plate 31 is provided with a limiting groove 311, and the limiting part of the rotary joint 5 is located in the limiting groove 311. The limiting plate 31 limits the rotation of the rotary joint 5. When the transmission shaft 4 rotates, the rotary joint 5 is limited by the limiting plate 31. The threaded connection part of the rotary joint 5 rotates with the transmission shaft 4, and the joint part remains stationary. This effectively avoids the possibility that the gas source / gas pipeline rotates with the transmission shaft when the transmission shaft 4 rotates.

[0034] In the embodiment, the end of the transmission shaft 4 away from the gas source is connected with an exhaust pipe (not shown in the figure), which is selectively connected to the inside of the kiln body 1 or to the outside of the transmission box 3 and communicates with the atmosphere. Specifically, if the gas source connected with the rotary joint 5 is compressed air, the exhaust pipe is selectively connected to the outside of the transmission box 3 and communicates with the atmosphere, that is, the compressed gas is directly discharged into the atmosphere after taking away the heat on the transmission shaft 4; if the gas source connected with the rotary joint 5 is nitrogen, the exhaust pipe is selectively connected to the inside of the kiln body 1, and the nitrogen is heated after taking away the heat of the transmission shaft 4 and can be used as the atmosphere transported into the kiln body 1, which can effectively reduce the power consumption of the kiln in heating nitrogen. And after the temperature of the transmission mechanism is reduced, a large amount of nitrogen is not needed to be introduced into the transmission box 3 to take away the heat of the transmission mechanism, only a small amount of nitrogen needs to be introduced into the transmission box 3 to maintain a slightly positive pressure state, which effectively reduces the loss of nitrogen and can effectively reduce the possibility of nitrogen overflow. In some embodiments, nitrogen can not be introduced into the transmission box 3, and only gas can be introduced into the transmission shaft 4.

[0035] Further, the transmission shaft 4 is rotatably connected with a plurality of bearing seats 42, and the bearing seats 42 are fixedly connected in the transmission box 3 to realize stable rotation of the transmission shaft 4 in the transmission box 3.

[0036] Further, the roller bar 11 is provided with roller support seats 6 at both ends, and the roller support seats 6 at both ends are fixedly arranged in the roller bar boxes 2 on both sides. The roller support seat 6 is used to fix and support the roller bar 11 to ensure stable operation of the roller bar 11 in a high-temperature environment and can also prevent the roller bar 11 from being bent or deformed under the action of high temperature and load. The roller support seat 6 can also reduce the direct contact between the roller bar 11 and the furnace body or other components, and reduce the wear of the roller bar 11.

[0037] In the embodiment, the roller support seat 6 is provided with rotating grooves 61 corresponding to the roller bars 11, and the rotating grooves 61 are provided with rolling bearings 62 located on both sides of the roller bars 11, and the rolling bearings 62 on both sides are in rolling contact with the outer periphery of the corresponding roller bars 11. The rolling bearings 62 are arranged to realize the rotary connection between the roller bar 11 and the roller support seat 6, effectively reducing the direct contact between the roller bar 11 and the roller support seat 6, thereby reducing wear and prolonging the service life of the roller bar 11.
