[0002] A pyrolysis furnace is a reaction device that decomposes solid materials into gaseous, liquid, and solid forms through thermochemical conversion. It is widely used in a variety of fields, including the treatment of solid waste such as scrap tires, plastics, and rubber, as well as in the production processes of industries such as biomass energy and petrochemicals. Pyrolysis furnaces utilize high temperatures to cause thermal cracking of solid materials, generating gaseous, liquid, and solid products. In this process, macromolecular compounds in the raw materials are broken down into smaller molecules at high temperatures, resulting in reusable products such as fuel oil and carbon black, while also reducing environmental pollution.

[0003] At present, carbon black is produced during the pyrolysis process of waste tires in the pyrolysis furnace. Carbon black is usually a black powdery solid substance with a certain adsorption capacity and is easy to adhere to the inner wall of the furnace body. The accumulation of carbon black will affect the heat transfer efficiency of the pyrolysis furnace. Therefore, it is necessary to shut down the furnace regularly to allow staff to clean the carbon black on the inner wall of the furnace body, which affects production efficiency and increases the workload of staff.

[0010] A push ring is provided near one end of the inner wall of the furnace body, and the push ring can push the cleaning component to clean the carbon black on the inner wall of the furnace body as the furnace body rotates;

[0011] The feeding device is arranged on the support frame and is used to transport the cleaned carbon black to the outside of the furnace body.

[0012] Furthermore, fixing rods are symmetrically provided at both ends of the support frame, and the support frame is fixed to the supporting device through the fixing rods, so that the support frame is overhead arranged in the furnace body.

[0013] Furthermore, the cleaning assembly includes a connecting rod and multiple cleaning scrapers, and the multiple cleaning scrapers are fixed by the connecting rod.

The overhead arrangement can prevent the supporting frame 5 from contacting the furnace body 2;

[0032] A gear ring 15 is sleeved on the furnace body 2, and a driving device 16 that cooperates with the gear ring 15 is provided on the device frame 1, so that the furnace body 2 can rotate under the cooperation of the gear ring 15 and the driving device 16;

[0033] The carbon black cleaning mechanism is arranged above the support frame 5. The carbon black cleaning mechanism includes a support frame 6 and a support rod 7. A limit rod 8 is arranged in the support frame 6, and a cleaning component 9 slidably connected to the limit rod 8. The cleaning component 9 includes a connecting rod 91 and multiple cleaning scrapers 92. The multiple cleaning scrapers 92 are fixed by the connecting rod 91. A spring 93 is arranged between the cleaning scraper 92 closest to one end of the cleaning component 9 and an inner end surface of the support frame 6. The spring 93 is sleeved on the limit rod 8, and a first arc-shaped top block 94 is connected to the side of the cleaning scraper 92 closest to the other end of the cleaning component 9. A limit hole is provided on the cleaning scraper 92 that is slidably connected to the limit rod 8. The top of the cleaning scraper 92 is set to an arc structure and fits against the inner wall of the furnace body 2. A push ring 11 is provided near one end of the inner wall of the furnace body 2. The push ring 11 includes The ring body 111 is fixed on the inner wall of the furnace body 2, and a second arc-shaped top block 112 is provided on the side of the ring body 111. During the rotation of the furnace body 2, the pushing ring 11 can be driven to rotate, and then the second arc-shaped top block 112 of the pushing ring 11 will come into contact with the first arc-shaped top block 94 on the side of the cleaning scraper 92, thereby pushing the cleaning scraper 92 to move. At the same time, the spring 93 is compressed, and the cleaning scraper 92 scrapes off the carbon black on the inner wall of the rotating furnace body 2.

As the cleaning scraper 92 works, the carbon black attached to the inner wall of the furnace body 2 is scraped off, and then falls into the feeding dragon 12, and is discharged from the furnace body 2 through the feeding dragon 12 and the discharge pipe.

[0036] Specifically, the driving device 16 can be started, and the driving gear ring 15 drives the furnace body 2 to rotate. During the rotation of the furnace body 2, the pushing ring 11 is driven to rotate, and then the second arc-shaped top block 112 of the pushing ring 11 will come into contact with the first arc-shaped top block 94 on the side of the cleaning scraper 92, thereby pushing the cleaning scraper 92 to move. At the same time, the spring 93 is compressed. As the pushing ring 11 rotates, when the second arc-shaped top block 112 no longer contacts the first arc-shaped top block 94, the cleaning scraper 92 is reset under the action of the spring 93. Therefore, as the pushing ring 11 rotates, the second arc-shaped top block 112 repeatedly contacts the first arc-shaped top block 94, causing the cleaning scraper 92 to move back and forth continuously, thereby cleaning the carbon black on the inner wall of the furnace body 2. The carbon black on the inner wall of the rotating furnace body 2 is scraped off by the cleaning scraper 92, and the scraped carbon black will fall on the feeding device, and the carbon black is transported to the discharge pipe by the feeding dragon 12, and then discharged out of the furnace body 2 through the discharge pipe.
