Description

Technical Field

[0001] The present invention belongs to the technical field of biomass particle carbonization, and specifically relates to a carbonization device for biomass particle production. Background Art

[0002] With the increasing global emphasis on renewable energy and the continuous growth of demand, biomass energy, as a clean and renewable energy form, has received extensive attention and application. Biomass particles, as an important form of biomass energy, have the advantages of high energy density, easy storage and transportation, etc., and occupy an important position in the field of biomass energy. In the production process of biomass particles, carbonization is a key link. The carbonization process can not only convert biomass particles into carbonized products with higher energy density, but also reduce the volatile matter and moisture in biomass, improving its combustion efficiency and stability.

[0003] When the existing carbonization devices for biomass particle production carbonize biomass particles of different material qualities, since biomass particles of different density materials require different heating temperatures for carbonization, it is necessary to manually adjust the distance between the heating tube and the carbonization inner cylinder to control the heating temperature of the inner cylinder by the heating tube. This not only takes time for each adjustment, reducing production efficiency, but also is prone to improper adjustment, which may lead to unstable quality of carbonized products, increasing the waste rate and reprocessing cost.

[0094] Working principle or structural principle: When in use, first start the auger conveyor 2, and then place the biological particles to be carbonized on the feeding hopper on one side of the auger conveyor 2. The biomass particles are conveyed by the auger conveyor 2 and placed on the feeding hopper 303, and then fall into the storage tank 323 through the feeding hopper 303. As the biomass particles continue to be conveyed, the biomass particles fall into the storage box 314 through the discharge port three 325 on one side of the storage tank 323. When the storage box 314 is full of biomass particles, the biomass particles continue to accumulate in the storage tank 323. When the biomass particles gradually accumulate at the conical opening of the feeding hopper 303, the self-weight of the biomass particles causes the feeding hopper 303 to slide downward in the cavity between the outer shell 302 and the storage tank 323. At the same time, the feeding hopper 303 drives the sliding rod 306 to slide downward in the receiving hole on the outer shell 302 and compress the compression spring 307. When the bottom of one side of the feeding hopper 303 contacts the wedge-shaped clamping column two 326, the wedge-shaped clamping column two 326 slides to one side on the outer shell 302 through the inclined surface at the upper end of the wedge-shaped clamping column two 326. At the same time, the wedge-shaped clamping column two 326 drives the wedge-shaped clamping column one 310 to move through the connecting rod 309 and compress the two groups of return springs one 311. When the wedge-shaped clamping column two 326 is clamped in the clamping groove one 308, the wedge-shaped clamping column one 310 disengages from the clamping groove two 315. At this time, one side of the feeding hopper 303 closes the discharge port three 325, and at the same time, the discharge port one 321 on one side of the feeding hopper 303 corresponds to the conveying cylinder 324. Due to the inclined setting at the bottom of the storage tank 323, the biomass particles slide onto the conveying cylinder 324 through the discharge port one 321 and are conveyed into the carbonization inner cylinder 413 through the conveying cylinder 324. When the wedge-shaped clamping column one 310 is driven by the connecting rod 309 to disengage from the clamping groove two 315, the storage box 314 slides downward on the sliding groove 313 due to the self-weight of the biomass particles. The storage box 314 drives the vertical rod 318 to slide downward on the outer shell 302 and compress the return spring two 319. The vertical rod 318 drives the connecting plate 320 to move downward, and the connecting plate 320 drives the rack 401 to slide downward in the vertical groove 402. The rack 401 drives the first circular gear 403 to rotate on the carbonization outer cylinder 301. The first circular gear 403 drives the second circular gear 404 to rotate on the carbonization outer cylinder 301. The second circular gear 404 drives the first transmission shaft 405 to rotate on the carbonization outer cylinder 301. The first transmission shaft 405 drives the first bevel gear 406 to rotate. The first bevel gear 406 drives the second bevel gear 407 to rotate. The second bevel gear 407 drives the round rod 408 to rotate on the carbonization outer cylinder 301. The round rod 408 drives the transmission gear 409 to rotate. The transmission gear 409 drives the circular tooth disc 410 to rotate at the bottom end of the carbonization inner cylinder 413. The rotation of the circular tooth disc 410 drives the four groups of heating rods 414 to slide inward on the limiting groove two 412 through the guidance of the guiding groove 411. The distance that the storage box 314 descends due to the different material qualities and self-weights of the carbonized biomass particles in the storage box 314 is used to adjust the distance between the four groups of heating rods 414 close to the carbonization inner cylinder 413.The higher the density of the biomass particles to be carbonized, the higher the required temperature. At the same time, the greater the density, the heavier the self-weight of the biomass particles. By storing the same volume of biomass particles in the storage box 314 each time during carbonization, the self-weight of the biomass particles can be used to adaptively adjust the contact distance between the four groups of heating rods 414 and the carbonization inner cylinder 413. The adaptive adjustment of the heating distance enables particles of different densities to be carbonized at the most suitable temperature without the need to replace equipment or perform complex setting adjustments, ensuring consistent carbonization of the biomass particles, thereby improving the uniformity and quality stability of the product. Before carbonization, one end of the exhaust pipe 603 can be flange-connected to an air purification device to prevent the gas generated during carbonization from polluting the air. During the carbonization process, the oxygen contact amount in the carbonization inner cylinder 413 can be adjusted according to the valve 602 to further control the temperature in the carbonization inner cylinder 413. At the same time, the stirring component in the carbonization inner cylinder 413 can be turned on during carbonization to further increase the uniformity of the heat received by the biomass particles in the carbonization inner cylinder 413, improving the uniformity of carbonization. After carbonization is completed, turn the threaded rod 504 to rotate on the stopper 503. The stopper 503 is threadedly connected to the fixed plate 502 and drives the stopper 503 to slide to one side in the discharge cylinder 501. When one end of the threaded rod 504 disengages from the fixed plate 502, pull the stopper 503 to completely slide out of the discharge cylinder 501 to discharge the carbonized particles in the carbonization inner cylinder 413, facilitating the subsequent discharge of the carbonized particles. After the carbonization of the biomass particles of this material is completed, the staff climbs to the storage box 314 through auxiliary tools, and then turns the bolt 317. The bolt 317 is threadedly connected to the box door 316 and the storage box 314 and moves to one side. When one end of the bolt 317 disengages from the storage box 314, pull the box door 316 to rotate on the storage box 314. At this time, the biomass particles stored in the storage box 314 slide down to the collection container through the inclined setting at the bottom of the storage box 314. After the biological particles are discharged, the storage box 314 slides upward on the chute 313 under the action of the rebound of the return spring two 319. When the upper end of one side of the storage box 314 contacts the inclined surface at the bottom of the wedge-shaped clamping column one 310, it drives the wedge-shaped clamping column one 310 to slide to one side on the outer shell 302. The wedge-shaped clamping column one 310 synchronously drives the wedge-shaped clamping column two 326 to move through the connecting rod 309 and compresses the return spring one 311. When the wedge-shaped clamping column one 310 is clamped on the clamping groove two 315 under the action of the rebound of the return spring one 311, the wedge-shaped clamping column two 326 disengages from the clamping groove one 308, and the feed hopper 303 is reset under the action of the rebound of the compression spring 307. When the storage box 314 rises, it drives the circular gear disk 410 to rotate in the reverse direction to reset the four groups of heating rods 414. Subsequently, fix the box door 316 on the storage box 314 with the bolt 317 to wait for the carbonization of the next group of biomass particles.,
