[0030] It should be further explained that a heater 2 is provided above the support frame 11. The lower end of the heater 2 is fixedly assembled to the surface of the support frame 11 through a bracket. The air outlet position of the heater 2 is flange-connected with an air duct 21. Hot air can be transported through the heater 2, thereby drying the catalyst distributed on the conveyor belt 111 with hot air.

[0031] It should be further explained that the end of the air duct 21 away from the heater 2 is a closed end, and a pipe seat 22 is fixedly sleeved on the surface of the closed end. The lower end of the outer wall of the pipe seat 22 is fixedly assembled with the upper end of the support frame 11 through a bracket.

Then, the conveying roller 110 on the linkage shaft 19 can be driven to rotate through the conveyor belt 111, so that the entire conveyor belt 111 can operate stably. The driving bearing 13 can ensure the stable rotation of the driving shaft 14, and the linkage bearing 18 can ensure the stable rotation of the linkage shaft 19. The catalyst is placed on the conveyor belt 111 for belt transportation;

[0038] Then, the heater 2 is powered on, and the heater 2 blows out hot air, which is transported through the air duct 21 and then divided by multiple air nozzles 23 so that the hot air flow can be evenly distributed on the conveyor belt 111 to dry the catalyst.

[0039] The structure of the shield 3 can prevent the catalyst from being blown or dropped from the conveyor belt 111 when the catalyst is dried by hot air. A number of air holes 31 are provided on the surface and side walls of the shield 3 to ensure the circulation of the hot air flow and the stable drying of the catalyst.
