[0002] Against the backdrop of rapid industrial development, the disposal of organic hazardous waste has become a major challenge in the environmental protection field. Traditional incineration and landfill methods not only pose a risk of secondary pollution but also result in resource waste. Meanwhile, anaerobic pyrolysis treatment equipment for hazardous waste, with its revolutionary technology of "harmlessness, volume reduction, and resource recovery," is becoming the benchmark choice in the hazardous waste treatment industry.

[0003] Utility model patent CN216890798U discloses a pyrolysis device suitable for solid hazardous waste, including: a feed inlet, a silo door, a pyrolysis tank, a display component, a recovery pipe, a conduit, a heat insulation seat, blades, a filter screen, a mounting bracket, a connecting pipe, a gas inlet, a frame, a display screen, a temperature sensor, a gas analyzer, a controller, a fixed base, a pyrolysis chamber, a partition screen, a heat recovery component, and a gas flow valve. The pyrolysis tank is installed on the lower end face of the feed inlet, the connecting pipe is installed on the lower right end face of the mounting bracket, the conduit is installed on the lower right end face of the recovery pipe, and the controller is installed on the left end face of the display screen. This patent can recover heat during the pyrolysis process by using the heat recovery component, and can effectively pyrolyze solid waste and obtain data during the pyrolysis process by using the display component and the pyrolysis tank, which is convenient for operators and improves the pyrolysis and heat recovery effect of this utility model.

[0004] However, the above-mentioned patents still have the following shortcomings: the position of the hazardous waste falling onto the mesh is fixed, which makes it difficult for the waste to move in the pyrolysis chamber and affects the quality of waste pyrolysis; in addition, the waste entering the pyrolysis chamber from the feed inlet is prone to clump together, affecting the pyrolysis efficiency. Therefore, we have proposed a pyrolysis device for the harmless treatment of hazardous waste. Utility Model Content

[0030] In this embodiment, a first motor 13 drives a crushing rod 14 and a spur gear 16 to rotate. The meshing transmission between the two spur gears 16 drives the two crushing rods 14 to rotate, and the crushing blades 15 on the crushing rods 14 crush the garbage.

[0031] For details, please refer to Figure 1 , Figure 3 and Figure 4 The ignition mechanism 9 includes a vacuum pump 21 fixedly installed on the side of the pyrolysis tank 1 and a gas distribution network 22 fixedly connected to the inner cavity of the pyrolysis tank 1. The gas distribution network 22 is located inside the conveying steel belt 3. Multiple gas ports 23 are provided on the top surface of the gas distribution network 22. An igniter 24 is provided on the top of the gas distribution network 22 and on the side of the gas ports 23. The output end of the vacuum pump 21 is connected to the gas distribution network 22.

[0032] In this embodiment, the input end of the air pump 21 is connected to an external gas tank through a pipe so that the gas can be introduced into the gas port 23 through the air pump 21 and the gas distribution network 22.

In addition, the inner wall of the pyrolysis tank 1 is used to limit the receiving box 11 to ensure that the receiving box 11 can catch the waste generated by pyrolysis.

[0039] Working principle: In operation, the first motor 13 is started, driving a crushing rod 14 and a spur gear 16 to rotate. The meshing transmission between the two spur gears 16 drives the two crushing rods 14 to rotate, which in turn drives the crushing blades 15 to rotate. At this time, the hazardous waste to be pyrolyzed is placed into the inner cavity of the feed hopper 6, and the crushing blades 15 crush the waste. The crushed waste falls onto the conveyor belt 3. Then, the second motor 5 is started, driving a conveyor roller 2 to rotate clockwise. The conveyor roller 2 drives the conveyor belt 3 and the waste on it to move forward. Simultaneously, the air pump 21 is started to introduce external gas into the gas distribution network 22, causing the gas to spray upwards from the gas port 23. Ignite the gas with igniter 24, and use the heat generated by the combustion of the gas to pyrolyze the waste on the conveyor belt 3. While the hazardous waste is being burned, temperature sensor 27 and gas analyzer 28 can analyze the temperature and harmful gases inside the pyrolysis tank 1 through control panel 26, and display the detected and analyzed data through control panel 26 for easy observation by staff. In addition, exhaust fan 20 is used to exhaust the high-temperature gas in the pyrolysis tank 1 through exhaust pipe 17. Finally, the waste produced by pyrolysis falls onto receiving box 11, so that the end cover 10 and receiving box 11 can be pulled out of the pyrolysis tank 1 by pulling handle 12 for processing of the waste produced by pyrolysis.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
