After the wet material in the mixing drum 9 is stirred and dispersed, the handle 828 is pulled. When the rack 2 824, the rack 3 825 and the gear 4 827 are meshed with each other, the two partitions 823 move outward at the same time, thereby connecting the collecting hopper 806 with the mixing drum 9, so that the wet material in the mixing drum 9 enters the feed box 6 and is transported into the box body 1.

[0031] In a specific application scenario, the stirring module 8 is mainly suitable for the stirring link in the stirring process, that is, the stirring module 8 can enable the device to pre-treat the wet material that needs to be dried, and disperse the agglomerates in the wet material by stirring and crushing the wet material, thereby assisting the drying process in the box 1 to prevent the wet material agglomerates from being quickly heated and solidified into a shell, making it impossible for the wet material in the shell to dry, thereby improving the drying effect.

[0032] Working principle: After the wet material is conveyed into the mixing drum 9 through the feed hopper 811, the drive motor 801 is started, and the drive motor 801 drives the main shaft 802 to rotate, so that the main stirring rod 804 stirs the wet material, and the rotating rod 803 on the main shaft 802 drives the secondary shaft 809 to stir synchronously. In the meshing of the gear 3 818 and the inner gear ring 808, the rotating gear 3 818 drives the secondary shaft 809 to rotate, so that the secondary stirring rod 810 further stirs the wet material. The short shaft 819 on the gear 3 818 pushes the transmission rod 820 to reciprocate when the gear 3 818 rotates, so that the crushing rod 807 reciprocates on the movable groove 812. At this time, the outer gear ring 817 is meshed with the rack 1 814 to make the outer gear ring 817 rotate, so that The crushing rod 807 is used to crush the agglomerated wet materials in the mixing drum 9. After the wet materials in the mixing drum 9 are stirred and dispersed, the handle 828 is pulled. When the rack 2 824, the rack 3 825 and the gear 4 827 are meshed with each other, the two partitions 823 move outward at the same time, thereby connecting the collecting hopper 806 with the mixing drum 9, so that the wet materials in the mixing drum 9 enter the feed box 6 and are transported into the box body 1. The servo motor 10 is started. The servo motor 10 drives the conveyor belt 14 to divert the wet materials through the diverter grate 15 and transport them to the conveyor belt 2 16. The heating tube 18 is started. The heating tube 18 generates high-temperature gas. The high-temperature gas rises upward to the conveyor belt 2 16 to dry the wet materials on the conveyor belt 2 16. The servo motor 11 is started. The servo motor 12 is driven by the servo motor 13. The service motor 11 drives the conveyor belt 16 to convey the wet material to the conveyor belt 3 19, and the high-temperature gas continues to dry the wet material on the conveyor belt 3 19, and the dried material is discharged through the discharge port 3. When the heating tube 18 is started to dry the wet material in the box body 1, after the wet material that has been continuously dried falls onto the conveyor belt 16, the motor 712 is started, and the motor 712 drives the winding roller 711 to rotate, so that the winding roller 711 reels the wire rope 715, so that the protrusion 724 connected to the insulation plate 703 drives the insulation plate 703 to move on the guide rail 702 toward the discharge port 3. After the insulation plate 703 is attached to the inner wall of the box body 1, the air holes 707 on the insulation plate 703 and the closing plate 706 will lower the box. The heat passing rate inside the whole body 1 is improved. When the material has a higher moisture content requirement, the motor 1 712 is started and the motor 1 712 is reversed, so that the winding roller 2 718 reels the wire rope 2 722, thereby pulling the insulation plate 703 back to its original position through the protrusion 2 723 connected to the wire rope 2 722, and the driving motor 1 727 is started. The driving motor 1 727 drives the screw rod 728 to rotate, so that the connecting plate 726 on the screw rod 728 pushes the closing plate 2 705 to drive the closing plate 1 706 to move toward the inner wall of the box body 1 away from the discharge port 3. After the closing plate 1 706 is completely fitted with the inner wall of the box body 1, the closing plate 2 705 will overlap with the insulation plate 703 and cover the air hole 707 on the insulation plate 703 to prevent the hot air from flowing.The hot air can only flow out through the insulation plate 703 on the forward-moving closing plate 706, thereby performing regional control on the drying temperature in the box 1, and starting the exhaust fan 5 to collect and discharge the evaporated water vapor in the box 1 through the moisture collecting pipe 4.
