A bottom groove 6 is provided on the bottom wall of the rotating rod 8, and a circular cavity is provided inside the rotating rod 8. A plurality of stirring shafts 9 are provided on the outer wall of the rotating rod 8, and the plurality of stirring shafts 9 at the bottom all penetrate the outer wall of the rotating rod 8 and pass through the circular cavity and extend into the bottom groove 6 at the same time. A fixing rod 7 is fixedly provided on the inner bottom wall of the pot body 1, and the lowest stirring shaft 9 is connected to the fixing rod 7 through a rotating mechanism, and the ends of the remaining rotating rods 8 all extend into the circular cavity and the corresponding rotating rods 8 above and below are connected by a transmission mechanism.

[0025] The elastic mechanism includes a spring 5 sleeved on the outside of the T-shaped rod 4, and the two ends of the spring 5 are elastically connected to the outer wall of the head of the T-shaped rod 4 and the arc-shaped outer wall of the upper cover 2 respectively. Under the action of the elastic potential energy provided by the spring 5, the end of the T-shaped rod 4 will be in the slot on the outer wall of the pot body 1, thereby realizing a stable connection between the pot body 1 and the upper cover 2. When disassembling, grab the head position of the T-shaped rod 4 and drag it to make its end disengage from the slot to complete convenient disassembly.

[0026] The driving mechanism includes a driving motor arranged on the upper end surface of the upper cover 2. The output shaft of the driving motor rotates through the upper cover 2 and is fixedly connected to the end of the rotating rod 8. The driving motor is the power device of the rotating rod 8 and can realize the driving and rotating operation of the rotating rod 8.

[0027] The rotating mechanism includes a rotating gear 12 arranged on the end of the stirring shaft 9, and a fixed gear 11 meshing with the rotating gear 12 is provided at the end of the fixed rod 7. As shown in the figure, the fixed gear 11 and the rotating gear 12 are both bevel gears.

At this time, the power of the pot body 1 is turned on to make it work so as to perform the drying operation. At the same time, the driving motor is started, and the driving motor can drive the rotating rod 8 to rotate. When the rotating rod 8 rotates, the spherical graphite is stirred with the help of the stirring shaft 9 and the stirring rod 10 to ensure uniform heating and thus ensure drying efficiency and effect. At the same time, the multiple stirring shafts 9 at the bottom rotate together with the rotating gear 12 relative to the fixed gear 11, so the rotating gear 12 can drive the multiple stirring shafts 9 at the bottom to rotate, and at the same time cooperate with the transmission gear 13 and the meshing gear 14 to realize the synchronous rotation of the remaining stirring shafts 9. Finally, each stirring shaft 9 rotates to drive the stirring rod 10 to rotate to realize the stirring of the spherical graphite.
