[0050] Among them, the heat-conducting sleeve 504 is fixedly connected to one side of the inner wall of the dehydration cylinder 103, one end of the carbon tube furnace return pipe 503 passes through the inner wall of the dehydration cylinder 103 and is connected to the top of the outer wall of the heat-conducting sleeve 504, and the other end of the carbon tube furnace return pipe 503 is connected to the cooling circulation return water pipeline of the high-temperature furnace 101, one end of the delivery pipe 501 passes through the inner wall of the dehydration cylinder 103 and is connected to the bottom of the outer wall of the heat-conducting sleeve 504, and the other end of the delivery pipe 501 is connected to the drain outlet of the circulation pump 502, one end of the carbon tube furnace heat exchange pipe 505 is connected to the water inlet of the circulation pump 502, and the other end of the carbon tube furnace heat exchange pipe 505 is connected to the cooling circulation drain pipeline of the high-temperature furnace 101.

[0051] The circulating cooling medium after absorbing heat is extracted by the circulating pump 502 using the carbon tube furnace heat exchange tube 505 and injected into the interior of the heat-conducting sleeve 504 through the delivery pipe 501, so that the inner cylinder 401 is heated by the circulating cooling medium through the heat-conducting sleeve 504.

[0052] In one embodiment, a damping knob 62 is rotatably connected to one side of the dehydration cylinder 103, one end of the damping knob 62 passes through the inner wall of the dehydration cylinder 103 and is fixedly connected to a material blocking plate 61, the outer wall of the material blocking plate 61 is slidably connected to the inner wall of the dehydration cylinder 103, and a feed pipe 63 is connected to the bottom of one side of the dehydration cylinder 103.

[0054] In one embodiment, a top side of the outer side wall of the dehydration cylinder 103 is connected to a feed hopper 64 , and a bottom side of the outer side wall of the dehydration cylinder 103 is connected to a sewage pipe 65 .

[0055] The clean coal to be dehydrated and dried is added into the dehydration cylinder 103 by using the feed hopper 64 , and the water filtered out by the filter cylinder 204 is discharged through the provided sewage pipe 65 .

[0056] When the utility model is working: the clean coal to be dehydrated and dried is added into the interior of the dehydration cylinder 103 by utilizing the feed hopper 64, and then the clean coal is initially filtered by utilizing the filter cartridge 204, and then the central shaft 202 is driven to rotate by the output shaft of the driving motor 201, and the rotating central shaft 202 drives the auger piece 203 and the connecting frame 403 to rotate, and the rotating auger piece 203 drives the clean coal to be squeezed toward one side of the pressure plate 303, so as to utilize the pressure to squeeze out the residual water in the clean coal.

The rotating inner cylinder 401 drives the shifting piece 402 to shift and scatter the clean coal so that the clean coal can be evenly heated in the inner cylinder 401.

[0058] When the high-temperature coking in the high-temperature furnace 101 is completed and circulated cooling is performed, the circulating cooling medium after absorbing heat is extracted by the circulating pump 502 using the carbon tube furnace heat exchange pipe 505, and injected into the interior of the heat-conducting sleeve 504 using the conveying pipe 501, so that the inner tube 401 is heated by the circulating cooling medium through the heat-conducting sleeve 504, and then the clean coal inside is heated and dried by the inner tube 401 for heat conduction, thereby further reducing the moisture content in the clean coal, increasing the temperature of the clean coal, and thus improving the efficiency of high-temperature coking during the production of negative electrode materials for sodium ion batteries. Then, the circulating cooling medium after the heat exchange in the heat-conducting sleeve 504 is discharged through the carbon tube furnace return pipe 503, and transported to the cooling circulation return water pipeline of the high-temperature furnace 101, so that the cooling medium can circulate between the high-temperature furnace 101 and the heat-conducting sleeve 504.

[0059] When it is necessary to discharge the clean coal after heating and drying in the inner cylinder 401, it is only necessary to rotate the damping knob 62 to drive the material blocking plate 61 to open one side of the dehydration cylinder 103, so that the clean coal can be pushed out by the rotating inner cylinder 401 and the material stripping piece 402, and then the clean coal can be discharged from the dehydration cylinder 103 by the discharge pipe 63 for centralized collection.
