Description

Technical Field

[0001] The utility model relates to the field of thermal cracking equipment, and more specifically to whole tire thermal cracking equipment. Background Art

[0002] Whole tire pyrolysis is a technology for processing waste tires. Usually, the processed waste tires are cut into smaller pieces and then sent to a pyrolysis reactor for high-temperature pyrolysis, so as to convert the tires into high-value products such as fuel oil and carbon black.

[0003] When the whole tire thermal cracking equipment is in use, the cut waste tires are usually fed into the reaction tank through the feed pipe for processing. At this time, the high-temperature device is started to gradually raise the temperature inside the reaction tank to the set high temperature condition (usually between 400°C and 500°C). At this temperature, the tire begins to crack, and the cracked residues will remain on the inner wall of the reaction tank. Its harmful gases will be discharged from the reaction tank through the outlet pipe, thereby completing the thermal cracking of the tire.

[0004] In actual use of the prior art, since part of the substances produced during the thermal cracking of tire materials will adhere to the inner wall of the reaction tank and be difficult to remove, they will remain in the reaction tank for a long time and accumulate dirt, forming an insulation layer, which hinders the effective transfer of heat energy and leads to a decrease in thermal cracking efficiency. Therefore, a whole tire thermal cracking device is proposed. Utility Model Content

[0032] Example 1

[0033] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 , which is the first embodiment of the utility model, provides a whole tire thermal cracking device, including a reaction tank 1 and a support rod 101. Four support rods 101 are fixedly connected to the bottom of the reaction tank 1, and a catalytic and scraping component 2 is arranged inside the reaction tank 1.

[0034] Specifically, the catalytic and scraping assembly 2 includes a motor 201 fixedly mounted on the outer surface of the reaction tank 1, the output shaft end of the motor 201 is fixedly connected to a rotating rod 202, the outer surface of the rotating rod 202 is fixedly connected to a plurality of stirring rods 203, the side of the stirring rod 203 is fixedly connected to a scraper 204, the outer surface of the rotating rod 202 is connected to a turntable 205 via a bearing seat, the outer surface of the turntable 205 is provided with a plurality of nozzles 206, and the scraper 204 abuts against the inner wall of the reaction tank 1.

[0035] Furthermore, the starter motor 201 drives the rotating rod 202 to rotate. When the rotating rod 202 rotates, it drives the stirring rod 203 to rotate so as to stir the whole tire. When the stirring rod 203 moves, it drives the scraper 204 to move, so that the scraper 204 scrapes the material on the inner wall of the reaction tank 1, and drives the material to perform thermal cracking through the reaction tank 1. Further, the catalyst can be evenly sprayed and evenly covered on the reaction material through the nozzle 206 on the outer surface of the turntable 205, thereby accelerating the thermal cracking reaction rate, improving the cracking efficiency, and avoiding the difficulty in removing the material adhering to the inner wall of the reaction tank 1 during the thermal cracking process to form an insulation layer, resulting in a decrease in the thermal cracking efficiency.

[0036] Example 2

[0037] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 , which is the second embodiment of the utility model. This embodiment is based on the previous embodiment. An air outlet pipe 102 is provided on the upper surface of the reaction tank 1, and a harmful gas filter component 3 is provided inside the air outlet pipe 102.

[0038] Specifically, the harmful gas filtering assembly 3 includes a frame 301 fixedly connected to the inner wall of the outlet pipe 102, a slide rail 302 is provided inside the outlet pipe 102, a bracket 303 is slidably connected inside the slide rail 302, and a HEPA filter 307, an activated carbon filter 304, a UV photolysis and photo-oxidation catalytic filter 305 and a dust filter 306 are fixedly connected inside the bracket 303.

[0039] Furthermore, the harmful gas generated during the tire thermal cracking process floats to the outlet pipe 102 above the reaction tank 1. The dust, fine particles and harmful substances in the harmful gas can be filtered through the HEPA filter 307, the activated carbon filter 304, the UV photolysis photocatalytic filter 305 and the dust filter 306 in the outlet pipe 102, so as to purify the harmful gas and convert it into harmless gas, and discharge it from the reaction tank 1 through the outlet pipe 102. At the same time, the HEPA filter 307, the activated carbon filter 304, the UV photolysis photocatalytic filter 305 and the dust filter 306 can be removed from the outlet pipe 102 through the cooperation of the slide rail 302, the frame 301 and the bracket 303 for cleaning and replacement, and vice versa, they can be installed, thereby improving the air purification effect.

[0040] Working principle: When in use, the device is placed at the designated position through the support rod 101 on the lower surface of the reaction tank 1, and then the high temperature component 4 is started in advance to make the temperature in the reaction tank 1 reach between 400°C and 500°C. Subsequently, the feed pipe 104 is opened to allow the processed whole tire material to enter the reaction tank 1. After placement, the feed pipe 104 is closed through the sealing cover, and the motor 201 is started to drive the rotating rod 202 to rotate. When the rotating rod 202 rotates, it will drive the stirring rod 203 to rotate, so as to stir the whole tire. When the stirring rod 203 moves, it will drive the scraper 204 to move, so that the scraper 204 scrapes the material on the inner wall of the reaction tank 1, and drives the material to perform thermal cracking through the reaction tank 1. Further, the catalyst can be evenly sprayed and evenly covered on the reaction material through the nozzle 206 on the outer surface of the turntable 205, thereby accelerating the thermal cracking reaction rate, improving the cracking efficiency, and avoiding the difficulty in removing the material adhering to the inner wall of the reaction tank 1 during the thermal cracking process to form an insulating layer, resulting in a decrease in the thermal cracking efficiency, thereby reducing the inner wall adhesion problem and maintaining the efficient operation of the reaction environment.

[0041] The harmful gas generated during the tire thermal cracking process floats to the outlet pipe 102 above the reaction tank 1. The HEPA filter 307, the activated carbon filter 304, the UV photolysis photocatalytic filter 305 and the dust filter 306 in the outlet pipe 102 can filter the dust, fine particles and harmful substances in the harmful gas, so as to purify the harmful gas and convert it into harmless gas, and discharge it from the reaction tank 1 through the outlet pipe 102. At the same time, the HEPA filter 307, the activated carbon filter 304, the UV photolysis photocatalytic filter 305 and the dust filter 306 can be removed from the outlet pipe 102 through the cooperation of the slide rail 302, the frame 301 and the bracket 303 for cleaning and replacement, and vice versa, they can be installed, thereby improving the air purification effect.

[0042] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
