[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0023] See also Figure 1-6 As shown, a rotary drum drying equipment for recycling and processing waste plastic bottles includes a base plate 1, a support frame 2 and a rotating drum 3. The support frame 2 is connected to the top of the base plate 1, and the rotating drum 3 is rotatably connected to the support frame 2. A driving ring gear 4 is fixedly installed on the outer wall of the rotating drum 3, and a feed box 5 is installed on the outer wall of the support frame 2 through an L-shaped support plate. A one-use-one-standby drive assembly for driving the driving ring gear 4 to rotate is connected to the support frame 2, and a side plate 6 is installed on the outer wall of the support frame 2. A retractable pre-drying assembly is connected to the top of the side plate 6. The feed box 5 is connected to the rotating drum 3 at one end, so that the material in the feed box 5 can enter the rotating drum 3.
[0024] The one-for-one drive assembly includes a mounting frame 7, which is fixedly mounted on the top of the support frame 2. A drive gear 8 is rotatably mounted on the mounting frame 7, and the drive gear 8 is engaged with the drive ring gear 4. Square slot blocks 9 are fixedly mounted on both ends of the drive gear 8. A connecting plate 10 is fixedly mounted on the top of the support frame 2, and a groove is provided on the top of the connecting plate 10. The mounting frame 7 facilitates the installation and rotation of the drive gear 8. When the drive gear 8 is rotated, it can drive the drive ring gear 4 and the rotating drum 3 to rotate.
[0025] A driving screw 11 is rotatably installed on the inner wall of the groove, and a handle 12 is installed on one end of the driving screw 11. A movable seat 13 is screwed on the driving screw 11. There are two movable seats 13. A driving motor 14 is connected to the movable seat 13 by bolts. A square plate 15 is installed on the output shaft of the driving motor 14. When the driving screw 11 rotates, the two driving motors 14 can be displaced synchronously. At this time, the damaged driving motor 14 drives the square plate 15 away from the square slot block 9. At the same time, the other unused driving motor 14 can drive the square plate 15 into another square slot block 9, thereby achieving the purpose of quickly switching the driving motor 14.
[0026] The retractable pre-drying assembly includes a chute plate 16, which is fixedly mounted on both sides of the top of the side plate 6, a sliding plate 17 is slidably mounted in the chute plate 16, and a conveying device 18 is mounted on one end of the sliding plate 17. A top plate 19 is fixedly mounted on both sides of the top of the conveying device 18, and a hot air blower 20 is mounted on the outer wall of the top plate 19 through a mounting seat. An air duct 21 is fixedly mounted on the inner wall of the top plate 19, and one end of the air duct 21 is connected to the hot air blower 20. The air duct 21 is provided with a means for discharging the hot air. The electric telescopic rod 22 is fixedly mounted on the outer wall of the side panel 6, and a push plate 23 is mounted on the output end of the electric telescopic rod 22. The push plate 23 is fixedly mounted on the outer wall of the sliding plate 17. When the hot air blower 20 of the conveying device 18 is not in use, the user can make the electric telescopic rod 22 work and drive the push plate 23 and the sliding plate 17 to move, so that the sliding plate 17 can drive the conveying device 18 and the hot air blower 20 to move above the rotating drum 3. The utility model will reduce the occupied space.
[0027] When the utility model is in use, the user can first move the square plate 15 on a driving motor 14 into the square slot block 9. When drying the crushed plastic bottles, the user can place the plastic bottles into the rotating drum 3 through the feed box 5. Then the user can make the driving motor 14 work to drive the square plate 15 and the square slot block 9 to rotate, thereby driving the driving gear 8 and the driving ring gear 4 to rotate, and then driving the rotating drum 3 to rotate. At this time, the rotating rotating drum 3 can fully dry the plastic bottles. When a driving motor 14 on the utility model is damaged, the user can rotate the driving screw 11 through the handle 12, thereby driving the two moving seats 13 to perform synchronous displacement in the connecting plate 10. At this time, the damaged drive motor 14 will drive the square plate 15 to move, and the unused drive motor 14 will also drive another square plate 15 to move, until the square plate 15 on the unused drive motor 14 is placed in another square slot block 9. At this time, the unused drive motor 14 can drive the rotating drum 3 to work, which reduces downtime and improves efficiency. When the rotating drum 3 is working, the user can place the plastic bottles to be dried and crushed on the conveyor 18. When the hot air blower 20 is working, the hot air can be placed in the air duct 21, so that the hot air ejected from the air duct 21 can preheat the plastic bottles, thereby improving the subsequent drying efficiency of the plastic bottles. The conveyor 18 can convey the preheated plastic bottles to the feed box 5.
