[0026] The furnace tube 4 includes a middle tube section 401 and an end tube section 402. There are two end tube sections 402 and they are symmetrically installed at both ends of the middle tube section 401. The end tube sections 402 are installed in the avoidance groove 12 on the furnace shell 2. First flanges 403 are installed at both ends of the middle tube section 401. A second flange 404 is installed at one end of the end tube section 402 close to the middle tube section 401. The middle tube section 401 and the end tube sections 402 at both ends are connected by the first flange 403 and the second flange 404. The first flange 403 and the second flange 404 are fixedly connected by bolts 406 and nuts 407.

[0027] The support mechanism 5 includes a telescopic rod 501 and a support seat 502. The number of the telescopic rods 501 is two and they are installed on the outer wall of the furnace shell 2. The movable end of the telescopic rod 501 extends to the interior of the furnace shell 2. The support seat 502 is located inside the furnace shell 2 and is connected to the ends of the movable ends of the two telescopic rods 501. The end of the support seat 502 away from the side wall of the furnace shell 2 is an arc-shaped surface, which is convenient for better fitting with the middle pipe section 401. When unloading is required, the telescopic rod 501 is extended to drive the two support seats 502 to approach each other and contact with the middle pipe section 401, thereby supporting the middle pipe section 401 and completing the separation of the middle pipe section 401 and the end pipe section 402.

[0028] Convex rings 405 are installed at both ends of the middle pipe section 401, and an arc groove 503 matching with the convex ring 405 is opened on the support seat 502.

The end pipe section 402 is installed in the bearing seat 604. When the middle pipe section 401 is separated from the end pipe section 402, the first motor 605 works to drive the rotating shaft 601 to rotate, and the threaded section 602 located on the rotating shaft 601 rotates accordingly. The two sliders 603 drive the two end pipe sections 402 to move away from each other under the action of the threaded section 602, so as to realize the disassembly of the entire furnace tube 4. When the furnace tube 4 is installed, the middle pipe section 401 is placed on the support seat 502, and the first motor 605 is reversed, and the two end pipe sections 402 are driven to approach each other and contact with the middle pipe section 401 through the two sliders 603.

[0030] The rotating mechanism 7 includes a second motor 701, a gear 702, and a ring gear 703. The second motor 701 is installed on the side wall of one of the sliders 603. The end of the output shaft of the second motor 701 passes through the slider 603 and is installed with a gear 702. The outer periphery of the end above the gear 702 is installed with a ring gear 703. The ring gear 703 is meshed and connected with the gear 702. When the end pipe section 402 is connected to the middle pipe section 401 for heating, the second motor 701 drives the gear 702 to rotate. After the gear 702 is meshed with the ring gear 703, it drives the end pipe section 402 to rotate in the bearing seat 604, finally realizing the overall rotation of the furnace tube 4, ensuring that the furnace tube 4 is heated evenly.
