[0026] See also Figure 1 , the first connection end seat 6 is provided with two water-cooling heat dissipation devices, and the first connection end seat 6 and the second connection end seat 4 are also provided with temperature sensor interfaces. In this embodiment, the water-cooling heat dissipation device is a cooling water jacket, and the cooling water jacket is respectively embedded in at least one annular groove formed in the surface of the first connection end seat 6 and the second connection end seat 4. In detail, in the first connection end seat 6, the annular grooves are respectively a first annular groove 64 and a second annular groove 65, the first annular groove 64 is formed on the end face of the first connection end seat, the second annular groove 65 is formed on the side of the first connection end seat, and the second annular groove 65 is opened around the central axis of the first connection end seat 6, and in the second connection end seat 4, the annular groove of the second connection end seat 4 is a third annular groove 41, and the third annular groove 41 is formed on the side of the second connection end seat 4, around the central axis of the second connection end seat 4. The first connection terminal seat 6 is provided with a cooling water jacket 61 and a cooling water jacket 62, and the second connection terminal seat 4 is provided with a cooling water jacket 41, both of which are used to pass cooling water to cool the above-mentioned connection terminal seats to meet the temperature requirements of the power supply copper plate, and a temperature sensor interface 63 is provided on the first connection terminal seat 6 to detect the operating temperature of the first connection terminal seat 6.

[0027] Refer to Figure 1 The power supply copper disk and the first connection end seat 6 are connected by a bolt, and the bolt passes through the first connection end seat 6 and is threadedly connected to the first end of the graphite connection joint. A heat-insulating material is also laid between the inner sleeve 2 and the graphite connection joint to seal and fix and isolate the heat transfer of the graphite connection joint. The heat-insulating material is a hard heat-insulating material 3, which can prevent the heat of the graphite connection joint 1 from being transferred to the first connection end seat 6 and can also play a supporting role.

[0028] The second connection terminal seat 4 is connected to the high-temperature carbonization furnace by welding, and the second connection terminal seat 4 and the shell wall 10 of the high-temperature carbonization furnace are connected by welding to achieve a fixed connection between the entire wiring structure and the high-temperature carbonization furnace.
