In addition, valves (not shown in the figure) are provided on the first connecting pipe 5 and the second connecting pipe 7 to facilitate the adjustment of the closure of the pipeline.

[0025] In this embodiment, a turntable 9 is provided inside the furnace body 1, and a rotating mechanism is provided between the turntable 9 and the furnace body 1, and the rotating mechanism includes a driving motor 10 fixedly mounted on the outer wall of the furnace body 1, and a connecting shaft 11 is fixedly mounted on the output shaft of the driving motor 10, and a worm 12 is fixedly connected to the end of the connecting shaft 11 away from the driving motor 10, and a worm wheel 13 is meshed on the outer side of the worm 12, and a transmission shaft 14 is fixedly connected to the inner side of the worm wheel 13, and the upper end of the transmission shaft 14 is fixedly connected to the bottom of the turntable 9, wherein a mounting box 8 is fixedly mounted on the inner bottom wall of the furnace body 1, and the connecting shaft 11 extends to the interior of the mounting box 8, and the lower end of the transmission shaft 14 is connected to the interior of the mounting box 8 through a bearing, and the upper end of the transmission shaft 14 extends to the upper side of the mounting box 8.
