[0002] A biomass carbonization reactor is a device that pyrolyzes and carbonizes biomass raw materials (such as straw, wood chips, rice husks, fruit shells, etc.) under oxygen-deficient or oxygen-limited conditions to produce biochar. It controls the reaction temperature, time, and oxygen supply to cause a series of complex physicochemical changes in biomass, ultimately producing biochar, while also generating byproducts such as combustible gas and tar. It is commonly referred to as a biomass carbonization furnace.

[0034] Please see Figure 1-4 This utility model provides a new technical solution: a biomass carbonization reactor, including an outer shell 1, a support block 2 fixedly connected to the lower side of the outer shell 1, a carbonization furnace body 3 fixedly connected to the rear wall of the outer shell 1, a feed inlet 4 fixedly connected to the front side of the outer shell 1, the rear side of the feed inlet 4 extending into the interior of the outer shell 1, a discharge port 5 fixedly connected to the rear side of the outer shell 1, the front side of the discharge port 5 extending into the interior of the outer shell 1, both the feed inlet 4 and the discharge port 5 communicating with the interior of the carbonization furnace body 3, and both the feed inlet 4 and the discharge port 5 being equipped with a switching valve, and a gas distribution pipe 6 fixedly connected to the rear wall of the outer shell 1, the front side of the gas distribution pipe 6 being fixedly connected to the rear wall of the outer shell 1. The outer shell 1 is fixedly connected to six flame-sparking bases 7, which are arranged in a circular array. The flame nozzles of the six flame-sparking bases 7 all face the carbonization furnace body 3. A gas supply pipe 8 is fixedly connected to the left side of the outer shell 1. The right end of the gas supply pipe 8 extends into the interior of the gas distribution pipe 6, and the left end of the gas supply pipe 8 is connected to an external gas source. A striking mechanism is provided on the outer shell 1. The striking mechanism can strike the carbonization furnace body 3, thereby causing the residual material attached to the inner wall of the carbonization furnace body 3 to fall off through vibration. The striking mechanism includes six striking blocks 9, six sets of springs 11, a rotating ring 12, six blades 13, a toothed ring 14, a motor assembly 15, and a gear 17.
[0035] Furthermore, all six striking blocks 9 are mounted on the rear wall of the outer casing 1, and each of the six striking blocks 9 and the bottom wall of the outer casing 1 is rotatably connected to a rotating shaft 10. The six striking blocks 9 are rotatably connected to the outer casing 1 through the six rotating shafts 10. Six sets of springs 11 are respectively fixedly connected to the sides of the six striking blocks 9 that are far apart from each other, and the ends of the six sets of springs 11 that are far apart from each other are fixedly connected to the inner wall of the outer casing 1. The rotating ring 12 is rotatably connected to the front wall of the outer casing 1 and is sleeved on the outside of the feed inlet 4. The six blades 13 are respectively fixedly connected to Six blades 13 are arranged in a ring array on the outer surface of the rotating ring 12. The blades 13 can contact the striking block 9. The toothed ring 14 is fixedly sleeved on the outer surface of the rotating ring 12. The toothed ring 14 is located on the front side of the blades 13. The motor assembly 15 is fixedly connected to the front side of the housing 1. The output end of the motor assembly 15 is fixedly connected to the drive shaft 16. The rear end of the drive shaft 16 rotatably extends into the interior of the housing 1. The gear 17 is fixedly connected to the rear end of the drive shaft 16. The gear 17 and the toothed ring 14 are meshed together.
[0036] Furthermore, at the start of operation, the biomass material to be carbonized is fed into the carbonization furnace body 3 through the feed inlet 4. The switch valve installed on the feed inlet 4 can control the material input process, ensuring that the material enters the carbonization furnace body 3 smoothly and can close the feed inlet 4 when necessary. An external gas source delivers gaseous fuel (such as natural gas, coal gas, etc.) to the gas distribution pipe 6 through the gas supply pipe 8. After being distributed by the gas distribution pipe 6, the gaseous fuel enters six burner seats 7 arranged in a ring array. The burner nozzles of the burner seats 7 face the carbonization furnace body 3, heating the carbonization furnace body 3, causing the biomass material in the carbonization furnace body 3 to undergo a carbonization reaction in a high-temperature and oxygen-deficient environment, generating biochar and other products. After the carbonization reaction is completed, the switch valve on the discharge port 5 is opened to discharge the carbonized products from the discharge port 5, completing the carbonization process.
[0037] After the carbonization furnace has been used for a period of time, residual materials will adhere to the inner wall of the carbonization furnace body 3. To clean these residual materials, the motor assembly 15 is started, and its output end drives the transmission shaft 16 to rotate. The gear 17 at the rear end of the transmission shaft 16 rotates accordingly. Since the gear 17 is meshed with the toothed ring 14 fixedly sleeved on the outer surface of the rotating ring 12, the rotation of the gear 17 will drive the toothed ring 14 to rotate, thereby causing the rotating ring 12 to rotate on the front wall of the outer shell 1. When the rotating ring 12 rotates, the six blades 13 arranged in a ring array on its outer surface will rotate accordingly. When the blades 13 rotate to the position of contacting the striking block 9, they will push the striking block 9 to rotate around the rotating shaft 10. At this time, the striking block 9 overcomes the elastic force of the spring 11 connected to the inner wall of the outer shell 1, causing the spring 11 to be compressed. As the blade 13 continues to rotate, the blade 13 separates from the striking block 9. The striking block 9 quickly resets under the action of the spring 11, striking the carbonization furnace body 3 and causing the carbonization furnace body 3 to vibrate. Since the six striking blocks 9 and the six blades 13 are arranged in a ring array, as the rotating ring 12 continues to rotate, the six blades 13 will contact and separate from the six striking blocks 9 in sequence, causing the six striking blocks 9 to strike the carbonization furnace body 3, thereby causing the residual material attached to the inner wall of the carbonization furnace body 3 to fall off through vibration, completing the cleaning work.
[0038] Furthermore, this method allows for the removal of residual materials inside the furnace through tapping and vibration, ensuring that the residual materials are promptly removed and discharged, preventing them from occupying space inside the furnace. It also guarantees the purity of the carbonized materials and improves the practicality of the biomass carbonization furnace.
[0039] Structural Description: Outer Shell 1: Serves as the external structural frame of the entire carbonization reactor, supporting and protecting the internal components and providing a mounting base for other components.
[0040] Support block 2: It is fixedly connected to the lower side of the outer shell 1 and is used to support the entire reactor and make it stably placed in the corresponding position.

[0045] Flame-emitting base 7: There are six flame-emitting bases 7 in total, arranged in a ring array in front of the gas distribution pipe 6. The flame nozzles are all facing the carbonization furnace body 3.

[0047] Tapping Block 9: There are six tapping blocks 9 in total, all of which are installed on the bottom wall of the outer shell 1 and are rotatably connected to the outer shell 1 via the rotating shaft 10. They are used to tap the carbonization furnace body 3 under the push of the blade 13 and the action of the spring 11, so that the carbonization furnace body 3 vibrates and the residual material attached to the inner wall falls off through the vibration.

The opposite ends are fixedly connected to the inner wall of the outer shell 1. When the striking blocks 9 are pushed and rotated by the blades 13, the springs 11 are compressed. After the blades 13 separate from the striking blocks 9, the elastic force of the springs 11 causes the striking blocks 9 to quickly return to their original position, thereby achieving the striking of the carbonization furnace body 3.
[0050] Rotating ring 12: Rotatably connected to the front wall of the outer shell 1, sleeved on the outside of the feed port 4, with six blades 13 fixedly connected to its outer surface and a toothed ring 14 fixedly sleeved thereon.
