[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1-4A waste tire pyrolysis treatment device includes a heating chamber 1, with mounting holes on both sides of the heating chamber 1. A pyrolysis chamber 2 is rotatably connected to the two mounting holes. An annular filter plate 3 is fixedly connected inside the pyrolysis chamber 2. A circular hole is opened at one end of the pyrolysis chamber 2, and a connecting pipe 4 is fixedly connected inside the circular hole. A beating mechanism is provided at one end of the connecting pipe 4, which matches the annular filter plate 3. An annular frame 5 is fixedly connected to one end of the heating chamber 1. A driving mechanism is provided on one side of the annular frame 5. The connecting pipe 4 and the pyrolysis chamber 2 are both rotated by the driving mechanism. A three-way pipe 7 is rotatably connected to one end of the connecting pipe 4. An oil outlet pipe 8 and an air inlet pipe 9 are fixedly connected to the end of the three-way pipe 7 away from the connecting pipe 4, respectively. The air inlet pipe 9 is fixedly connected to one side of the annular frame 5.

[0022] refer to Figures 1-4 The beating mechanism includes a circular plate 10 and two beating plates 11. A through hole is provided on one side of the circular plate 10. The circular plate 10 is fixedly sleeved to the wall of the connecting pipe 4 through the through hole. The two beating plates 11 are symmetrically fixedly connected to one side of the circular plate 10. The sides of the two beating plates 11 are in contact with the inner wall of the annular filter screen plate 3. The driving mechanism includes a motor 12, a driving gear 13, a driven gear 14 and an internal gear ring 15. The motor 12 is fixedly connected to one side of the annular frame 5. The driving gear 13 is fixedly sleeved to the output end of the motor 12. The driven gear 14 is fixedly sleeved to the wall of the connecting pipe 4. The driving gear 13 meshes with the driven gear 14. The internal gear ring 15 is fixedly connected to one side of the pyrolysis chamber 2. The internal gear ring 15 meshes with the driving gear 13. The upper end of the oil outlet pipe 8 passes through the upper surface of the annular frame 5. Multiple stirring rods 20 are fixedly connected around the inner wall of the pyrolysis chamber 2.

[0023] The motor 12 of the drive mechanism is started, and then the drive gear 13 rotates, which in turn drives the driven gear 14 and the internal gear ring 15 to rotate. When the internal gear ring 15 rotates, it drives the pyrolysis chamber 2 to rotate slowly in the mounting hole of the heating chamber 1, which can continuously turn the waste tire blocks in the chamber, so that the tires can be heated evenly. At this time, the oil and gas generated by the tires at high temperature are discharged and collected from the oil and gas outlet pipe 8. When the driven gear 14 rotates, it drives the connecting pipe 4 to rotate, which causes the circular plate 10 to rotate and drive the two slapping plates 11 to slap the tires, separating the carbon black from the steel wire. Then the carbon black passes through the filter screen and falls into the bottom of the pyrolysis chamber, thus achieving the effect of separating it from the steel wire.

[0024] refer to Figures 1-2 A combustion chamber 16 is symmetrically and fixedly connected to the lower surface inside the heating chamber 1, and a gas pipe 17 is fixedly connected to one end of the combustion chamber 16.

[0025] Connect the gas pipe 17 to a fuel source such as natural gas or biomass gas, and then ignite the combustion exhaust 16 in the heating chamber 1. The heat released by the combustion exhaust raises the internal temperature of the heating chamber to the temperature required for the thermal pyrolysis of waste tires, providing a stable high-temperature environment for the thermal pyrolysis chamber 2. The thermal pyrolysis chamber is made of high-temperature resistant alloy material, which can withstand long-term high-temperature baking without deformation.

[0026] refer to Figures 1-2 A fan 6 is fixedly connected to one side of the annular frame 5. One end of the connecting pipe 4 passes through one side of the annular frame 5 and is fixedly connected to the output end of the fan 6. Two exhaust valves 22 are symmetrically arranged at one end of the pyrolysis chamber 2. Switch valves 21 are provided on the surface of the oil outlet pipe 8 and the air inlet pipe 9. A sealing door 18 is hinged to one end of the pyrolysis chamber 2. A handle 19 is fixedly connected to one side of the sealing door 18.

[0027] After the waste tires have undergone pyrolysis, the switch valve 21 on the surface of the oil outlet pipe 8 is closed, and the switch valve 21 and exhaust valve 22 on the surface of the air inlet pipe 9 are opened. Then, the blower 6 is started, and cold outside air is sent into the pyrolysis chamber 2. The cold air flows in the chamber, absorbs heat from the steel wire and the chamber wall, and is then discharged through the exhaust valve 22 at one end of the pyrolysis chamber. Thus, without the need for a long period of natural cooling, the sealing door 18 can be opened to remove the steel wire for the next batch of tires to be pyrolyzed.

[0028] In summary, during operation, this waste tire pyrolysis treatment device first inputs gas into the combustion chamber 16 through the gas pipe 17, then ignites the combustion chamber 16 to provide a stable high-temperature environment for the pyrolysis chamber 2. During this process, the oil and gas generated by the tire pyrolysis can be discharged through the oil and gas outlet pipe 8. Then, the motor 12 is started, driving the pyrolysis chamber 2 and connecting pipe 4 to rotate via gear transmission. The rotation of the pyrolysis chamber 2 causes the tire to flip, ensuring even heating. The rotation of the connecting pipe 4 drives two striking plates 11 to strike the tire, causing the circular plate 10 to rotate and drive the two striking plates 11 to strike the tire. The carbon black is separated from the steel wire by passing through the filter mesh and falling into the bottom of the pyrolysis chamber, thus achieving the effect of separation from the steel wire. After the waste tire is pyrolyzed, the switch valve 21 on the surface of the oil and gas pipe 8 is closed, and the switch valve 21 and exhaust valve 22 on the surface of the air inlet pipe 9 are opened. Then the fan 6 is started, and cold air from the outside can be sent into the pyrolysis chamber 2. The cold air flows in the chamber, absorbs the heat from the steel wire and the chamber wall, and is discharged through the exhaust valve 22 at one end of the pyrolysis chamber. Therefore, without the need for long-term natural cooling, the sealing door 18 can be opened to remove the steel wire for the next batch of tires to be pyrolyzed.
