3. A method for using a catalyst primary drying device, using the catalyst primary drying device as claimed in claim 2, characterized in that: The steps include: S1. Loading: Open the door panel (102), rotate one of the rotating handles (804), and the rotating handle (804) drives the spur gear (803) to rotate through the rotating rod (802). Since the rack (801) connected to the support frame (4) is meshed with the spur gear (803), the spur gear (803) can drive the support frame (4) and the sliding connecting plate (3) to move along the slide rail (2) to the outside of the box (101). When the support frame (4) moves outward to a certain extent, After reaching the distance, stop rotating the rotary handle (804), place the catalyst (504) to be dried on the removed support plate 1 (502) through the handling equipment, and then rotate the rotary handle (804) in the opposite direction to move the catalyst (504) on the support plate 1 (502) into the box body (101), rotate the other rotary handles (804) in turn, place the catalyst (504) on each row of the support plate 1 (502), and then close the door panel (102); S2, drying: heating the air in the box (101) to dry the catalyst (504). After a period of time, rotating the hand wheel (708), the rotating hand wheel (708) drives the transmission rod (702) to rotate through the driving rod (706), and the remaining transmission rods (702) rotate together under the drive of the belt transmission assembly (703). The transmission rod (702) drives the screw rod (602) to rotate through the meshing bevel gear 1 (604) and the bevel gear 2 (704). The screw rod (602) drives the moving block (603) threadedly connected thereto to translate along the slide groove (401), and the moving block (603) drives the main frame (501) slidably connected thereto to move. During the movement of the main frame (501), the spur gear 1 (507) first meshes with the rack gear 1 (516) and then moves to the main frame (501). The two gears are combined and rotated 180 degrees, driving the eccentric guide ring 1 (508) to rotate 180 degrees, and driving the support plate 1 (502) to slide along the main support (501) through the guide rod 1 (510) and the fixed support 1 (509), so that one side of the catalyst (504) is in contact with the support plate 2 (503), and then the spur gear 3 (515) and the rack 3 (518) are meshed and rotated 90 degrees, driving the main support (501) fixedly connected to the spur gear 3 (515) to rotate 90 degrees, so that the support plate 2 (503) is horizontal and the support plate 1 (502) is vertical, and finally the spur gear 2 (511) and the rack 2 (517) are meshed and rotated 180 degrees, so that the support plate 2 (503) slides along the main support (501), so that the catalyst (504) and the support plate 1 (502) are separated; S3, discharging: After drying is completed, the door panel (102) is opened, and the handle (804) is rotated to take out each row of catalysts (504) in turn.
