when the graphitization furnace 62 moves to the power transmission station of the graphitization zone 2, the graphitization furnace 62 is temporarily fixed by the rail 7 positioning and fixing device, then the graphitization furnace 62 is electrified and connected with the transformer 22, a furnace core consisting of furnace charging products 8 and resistance materials is heated by the resistance of the furnace core under the action of current, high-temperature graphitization is realized, meanwhile, in the graphitization process, high-temperature flue gas discharged from the graphitization furnace 62 is collected and processed in real time by the flue gas processing device 23, and then the flue gas is discharged after processing;

when the graphitization furnace 62 is moved to the cooling zone 3, the cooling circulation device 33 is used to perform circulating water cooling treatment on the high-temperature graphitization furnace 62, and at the same time, the second cooling device 32 is used to perform air cooling treatment on the high-temperature graphitization furnace 62;

when the graphitization furnace 62 moves to the discharging area 4, the graphitized materials in the graphitization furnace 62 are absorbed by the material absorbing mechanism 42 and conveyed to the second discharging mechanism, and then the materials are weighed and packaged; meanwhile, the heat insulating material 10 and the resistance material 9 between the box body 61 and the graphitizing furnace 62 are absorbed by the material absorbing mechanism 42 and conveyed to the screening mechanism 43 for screening treatment, the heat insulating material 10 and the resistance material 9 are separated from the materials, the two materials are independently stored in the first discharging mechanism 44, wherein the heat insulating material 10 can be conveyed to the auxiliary material charging device 13 through a pipeline for reuse.

When the graphitization furnace 62 breaks down, the graphitization furnace 62 can be moved to the maintenance area 5 through the traction device for troubleshooting, specifically, the graphitization device 6 after unloading and the crucible inside are conveyed to the maintenance station in the maintenance workshop through the rail 7 for maintenance, and after the maintenance is ensured to be not damaged, the graphitizing treatment is carried to the charging station of the charging workshop 11 for charging for the next time.

the walking wheels 63 are arranged at the bottoms of the first graphitization furnace 62 and move to the power transmission station of the graphitization workshop 21 through the rails 7 to be connected with the transformer 22, so that the power transmission distance of the transformer 22 is effectively shortened, and the power consumption loss is reduced;

secondly, the smoke treatment device 23 is arranged in the graphitization workshop 21, so that high-temperature smoke discharged by the graphitization furnace 62 can be treated in real time, and the problem of emission of a large amount of sulfur, asphalt and heavy metal smoke generated by carbon materials at high temperature in the graphitization production process is effectively solved;

thirdly, the loading and unloading device is fixedly arranged above the rail 7, and the corresponding loading and unloading operation is carried out by moving the graphitization furnace 62 on the rail 7, so that the mechanical automation degree is high, the equipment manufacturing difficulty is low, and the working efficiency is high;

fourthly, corresponding pipelines are arranged in the loading and unloading station areas of the loading and unloading workshop 41 and communicated with a dust treatment device, dust generated in the loading and unloading operation process is collected, the collected gas is used as power for transporting the recovered heat insulation material in the pipelines, a refractory containing component such as a crucible is used for installing the furnace loading product 8, and the crucible is lifted into and out of the graphitization furnace 62 only at the end part of the workshop by a crane, so that the cleanness, tidiness and order of the production site are effectively ensured;

fifthly, a plurality of tracks 7 are arranged in each workshop, so that the working efficiency is effectively improved through a dislocation method;
