When the second rotating sleeve 17 rotates, the second rotating sleeve 17 will drive the connecting ring 21 and the outer air cylinder 22 to rotate on the fixed column 7. The hot air in the air cavity of the fixed column 7 can flow into the exhaust pipe rack 23 through the outer air cylinder 22. Since a force receiving rod 19 is coaxially and fixedly connected to the end face of the cross plate 18, and the force receiving rod 19 slides through the inner wall of the second rotating sleeve 17. Two groups of equally angularly distributed extrusion blocks 20 are fixedly installed in the annular groove on the side wall of the fixed column 7, and the two groups of extrusion blocks 20 are arranged in a vertically staggered manner. And the end of the force receiving rod 19 is arranged in the gap between the extrusion blocks 20 to form a transmission structure.

Moreover, the other end of the docking rod 38 is arranged opposite to the docking hole 40 on the vertical plate 39. At the same time, the diameter of the docking hole 40 is larger than the diameter of the docking rod 38. When the docking rod 38 enters the docking hole 40, the vertical plate 39 will drive the lifting plate 33 to move through the docking rod 38.

The outer sleeve rod 3201 will drive the jet head 25 to move.

[0024] Working principle: When using the direct-fired high-efficiency energy-saving humidity-controlled denitration catalyst drying system, first refer to Figures 1 - 17 , the user places the denitration catalyst to be dried on the support table 15, so that both ends of the catalyst are between the air-permeable plate 16 and the moving frame 14. Then, the electric cylinder 11 is started. At this time, the electric cylinder 11 will drive the rotating ring 12 to move upward through the convex ring on the side wall of the loading ring 10, and the rotating ring 12 will drive the moving frame 14 to move on the support table 15 through the pull arm 13, so that the moving frame 14 can drive the pressure-bearing block 24 to move towards the end face of the catalyst. At this time, the corresponding pressure-bearing block 24 under the reverse pressure of the end face of the catalyst will move, while the pressure-bearing block 24 that does not contact the end face of the catalyst will not move. The moving pressure-bearing block 24 will compress the return spring 28. At the same time, the pressure-bearing block 24 will drive the corresponding moving air cylinder 27 to move, so that the docking air port 29 on the moving air cylinder 27 can communicate with the air outlet on the exhaust pipe rack 23. At the same time, the moving air cylinder 27 can drive the fixed frame 31 through the guide rod 30, and the fixed frame 31 will drive the docking rod 38 to move through the guide block 34 and the lifting plate 33, so that the end of the docking rod 38 can enter the docking hole 40 on the vertical plate 39. Then, the device controls the combustion rack 5 to spray flames to increase the gas temperature in the hot air box 3. The intake pipe 4 is used to supplement gas, and the started hot air blower 6 can send the high-temperature gas in the hot air box 3 into the air cavity at the bottom of the fixed column 7. The hot air in the fixed column 7 can enter the exhaust pipe rack 23 through the outer air cylinder 22. The hot air in the exhaust pipe rack 23 will sequentially pass through the docking air port 29, the moving air cylinder 27, the pressure-bearing block 24 and the ventilation port 26 into the jet head 25, and the hot air sprayed out of the jet head 25 will enter the through holes in the catalyst for efficient drying; Next, the motor 9 inside the user control device is started. At this time, the motor 9 will drive the first rotating sleeve 8 to rotate, and the first rotating sleeve 8 will drive the support platform 15 and the second rotating sleeve 17 to rotate synchronously. The catalyst on the support platform 15 will rotate synchronously. Since the hot gas will gradually cool down during the process of passing through the catalyst pores, and under the action of centrifugal force, the moisture in the catalyst will move towards the part closer to the jet head 25, making the moisture content of the catalyst higher at the position closer to the jet head 25, and the temperature of the hot gas ejected from the jet head 25 at this position is the highest. Therefore, the airflow ejected from the jet head 25 can dry the catalyst relatively evenly and quickly. At the same time, when the second rotating sleeve 17 drives the cross plate 18 to rotate, the force receiving rod 19 at the end of the cross plate 18 will be squeezed by different pressing blocks 20, enabling the force receiving rod 19 to drive the cross plate 18 to reciprocate up and down. Since the cross plate 18 is slidably installed through the bottom of the vertical plate 39, the cross plate 18 will drive the vertical plate 39 to reciprocate synchronously. A docking rod 38 is inserted into the docking hole 40 on the vertical plate 39. At this time, the vertical plate 39 will drive the lifting plate 33 to reciprocate up and down synchronously through the docking rod 38. The lifting plate 33 will drive the guide block 34 and the toothed plate 36 to move synchronously. During this process, the inclined groove 35 on the lifting plate 33 will push the convex rod 3205 to move, causing the thrust sleeves 3204 and the limit blocks 3206 on both sides of the convex rod 3205 to move horizontally reciprocally synchronously. The thrust sleeve 3204 will pull the outer sleeve rod 3201 to move synchronously, and the outer sleeve rod 3201 will drive the jet head 25 to move synchronously. At the same time, the moving toothed plate 36 will drive the transmission gear 3203 to move synchronously. The transmission gear 3203 will drive the embedded rod 3202 to rotate, and the embedded rod 3202 will drive the jet head 25 to rotate synchronously through the outer sleeve rod 3201, enabling the jet head 25 to periodically move away from or close to the end face of the catalyst and rotate, so that the hot gas ejected from the jet head 25 can more effectively enter the pores on the end face of the catalyst. The hot gas passing through the catalyst pores will carry out moisture, and an exhaust pipe is provided at the top of the housing 1 and connected to external equipment.
