[0002] In recent years, with the rapid growth of car ownership, the demand for tires has increased year by year, resulting in a rapid increase in waste tires at a double-digit growth rate. Currently, the main methods for recycling waste tires in my country include tire retreading, producing recycled rubber and rubber powder, and pyrolysis. Pyrolysis is the ultimate method for recycling waste tires. Through pyrolysis technology, waste tires can be decomposed into 45% fuel oil, 35% carbon black, 10% steel wire, and 10% combustible gas, which has significant economic value. Unlike traditional oil refining methods, pyrolysis technology can fully recover various resources from waste tires without polluting the environment, falling under the categories of circular economy and energy conservation and emission reduction.

[0003] Thermolytic pyrolysis of used tires is usually carried out by workers who cut the used tires with a cutting machine and then manually transport the tires into the pyrolysis furnace for incineration and pyrolysis. The commonly used cutting machine can only perform simple crushing and cutting of the tires. At the same time, relying on manual feeding by workers is slow and time-consuming. In order to address this technical problem, this application proposes a feeding device for high-temperature pyrolysis of scrapped automobiles. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Reference Figures 1-2 This utility model provides an embodiment of a feeding device for high-temperature pyrolysis of scrapped automobiles, including a feeding box 1, a conveyor belt 2 on the top of the feeding box 1, a power assembly 7 mounted on the top side of the feeding box 1 via a fixed bracket, iron plates 8 fixedly connected to both sides of the inner wall of the top of the feeding box 1, a cutting assembly connected to the power assembly 7 on the side of the two iron plates 8 that are close to each other, an inclined plate 10 fixedly connected to the middle of the inner wall of the feeding box 1, a feeding box 3 fixedly connected to the left side of the feeding box 1, a conveying pipe 4 fixedly connected to the bottom of the feeding box 3, a spiral roller 16 installed on the inner wall of the conveying pipe 4, and a sealing assembly connected to the pyrolysis furnace 6 on the left side of the conveying pipe 4.

[0018] Specifically, waste tires are transported into the feeding box 1 via the conveyor belt 2, and then fall down the slope into the cutting assembly between the iron plates 8. The cutting assembly is driven by the power assembly 7 to rotate and cut the waste tires. The tires then enter the feeding box 3 through the inclined plate 10, and are then conveyed into the pyrolysis furnace 6 through the spiral roller 16 in the conveying pipe 4 and the enclosed assembly.

[0019] Reference Figures 2-4 The cutting assembly includes a roller 11 located on one side of two iron plates 8. The outer wall of the roller 11 is rotatably connected to the inner wall of the feeding box 1. A rotating shaft 13 is fixedly connected to the inner wall of the roller 11. The end of the rotating shaft 13 is connected to the power assembly 7. Multiple cutting teeth 11 are fixedly connected to the end of the two iron plates 8 on one side of the two iron plates 8. Multiple cutting teeth 22 are fixedly connected to the outer wall of the roller 11. The power assembly 7 drives the rotating shaft 13 to rotate, which in turn drives the cutting teeth 22 on the roller 11 to rotate, thereby cooperating with the cutting teeth 119 to crush the tire.

[0020] The enclosure assembly includes an enclosure box 5 located on the left side of the conveying pipe 4. A sealing plate 17 is slidably connected to the inner wall of the enclosure box 5, and a connecting block 21 is fixedly connected to the top of the sealing plate 17. Cylinders 18 are installed around the right side of the enclosure box 5 via fixed brackets. The left side of the enclosure box 5 is connected to the pyrolysis furnace 6. A motor 19 is installed on the top of one side of the enclosure box 5 via a fixed bracket, and a connecting rod 24 is fixedly connected to the top of the other side of the enclosure box 5. Turntables 23 are provided on the drive end of the motor 19 and the inner wall of the connecting rod 24. The outer walls of the two turntables 23 are provided with leather straps. A fixed block 22 is fixedly connected to the inner wall of the belt 20 and the connecting block 21. The fixed block 22 is connected to the belt 20. The motor 19 drives one of the turntables 23 to rotate, thereby driving the belt 20 to move. The other turntable 23 is on the connecting rod 24, thereby driving the fixed block 22 on the belt 20 to move back and forth. This causes the sealing plate 17 at the bottom of the connecting block 21 to slide open and close on the inner wall of the sealing box 5. When the sealing plate 17 is closed, the four cylinders 18 will push against the sealing plate 17 to prevent the sealing plate 17 from opening.

[0021] Both the feeding box 3 and the loading box 1 are provided with a feeding port 14, and both the feeding box 3 and the conveying pipe 4 are provided with a feeding port 25. Waste tires enter the feeding box 3 from the loading box 1 through the feeding port 14, and at the same time enter the conveying pipe 4 from the feeding box 3 through the feeding port 25.

[0022] Working principle: Waste tires are transported into the feeding box 1 via conveyor belt 2, and then fall onto the rollers 11 between the iron plates 8 via a ramp. The rotating shaft 13 is driven by the power component 7, which is an electric motor that drives the gears to rotate, thereby driving the rotating shaft 13 to rotate. This, in turn, drives the cutting teeth 12 on the rollers 11 to rotate, thus crushing the tires in conjunction with the cutting teeth 9. The tires then slide through the inclined plate 10 into the feed inlet 14 and enter the feeding box 3. At the same time, they enter the feeding box 3 through the feed inlet 15. In the conveying pipe 4, the material is then conveyed into the pyrolysis furnace 6 via the spiral roller 16 inside the conveying pipe 4. During conveying, one of the turntables 23 is driven to rotate by the motor 19, which in turn drives the belt 20 to move. This drives the other turntable 23 on the connecting rod 24, which in turn drives the fixed block 22 on the belt 20 to move back and forth. This causes the sealing plate 17 at the bottom of the connecting block 21 to slide open and close on the inner wall of the sealing box 5. When the sealing plate 17 is closed, the four cylinders 18 will press against the sealing plate 17 to prevent the sealing plate 17 from opening.

[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
