Description

Technical Field

[0001] The invention relates to the technical field of bamboo desugaring and carbonization, in particular to a bamboo desugaring and carbonization device and a bamboo desugaring and carbonization method. Background Art

[0002] Bamboo is a renewable green building and industrial raw material with excellent strength and elasticity. During the processing of bamboo, especially during high-temperature treatment, the desugaring and carbonization process is an important means to improve the performance of bamboo.

[0003] Bamboo desugars and carbonizes in a high temperature environment, decomposes sugar substances and gradually carbonizes. In this process, the control of temperature and steam is crucial, because high temperature will accelerate the decomposition of lignin and hemicellulose. Appropriate steam and atmosphere can prevent excessive carbonization and uneven carbonization. The bamboo after pyrolysis and desugaring carbonization needs to be cooled quickly to solidify the carbonization structure. After cooling, the bamboo becomes harder and more corrosion-resistant and insect-proof. When the existing bamboo desugaring carbonization device performs steam injection, due to the long size of the carbonization furnace, the steam cannot flow quickly to every position of the carbonization furnace, and due to the high density of bamboo placement, the steam cannot quickly reach the center of the bamboo pile during the circulation process, which will cause the bamboo in the middle of the bamboo pile to heat up slowly, and the bamboo outside the bamboo pile to heat up quickly, which is easy to cause a temperature difference between the two areas, affecting the desugaring carbonization effect of the bamboo. In addition, during the bamboo desugaring carbonization process, the tar and resin deposits secreted by the bamboo will adhere to the inner wall of the carbonization furnace. If they are not cleaned in time, an adhesion layer will be formed. When there is a lot of accumulation, it is easy to affect the carbonization operation of the bamboo, so it needs to be improved.

[0013] Preferably, the drying mechanism comprises an air intake valve, an output end of the air intake valve is connected to an air intake pipe, and an end of the air intake pipe away from the air intake valve is fixedly connected to an air diffuser.

[0015] Preferably, the transmission shaft passes through the frame, the rear chamber, the carbonization furnace and the mounting plate and is fixedly connected to the second gear, and the side wall of the air delivery pipe is slidably mounted in the guide rail.

[0016] Preferably, a desugaring and carbonizing method of a bamboo desugaring and carbonizing device comprises the following steps:

[0017] S1: Before carbonization begins, bamboo is placed on the carbonization rack. After the bamboo is placed on the carbonization rack, a bamboo pile is formed. A gap for ventilation is reserved between each bamboo. The carbonization rack is pushed into the carbonization furnace along the feed rail. Then the furnace cover is closed, the exhaust valve is closed, and the steam valve is opened. The steam generated in the boiler is transported to the two horizontal pipes through the steam valve, and then flows out to the outlet valve through the hose. The outlet valve is opened, and the steam fills the inside of the gas pipe and continues to extend to the far end. It is sprayed into the inside of the carbonization furnace through several nozzles on the gas pipe, and a high-temperature and high-humidity desugaring carbonization environment is quickly formed in the carbonization furnace;

[0018] S2: Then the driving motor is started, and the output end of the driving motor drives the turntable to rotate continuously. The side of the turntable connected to the slide rail drives the slide rail to move to one side on the frame. In the process, the rack 1 drives the gear 1 to rotate. When the turntable rotates half a circle, it drives the slide rail to return to its original position, so that the rack 1 drives the gear 1 to rotate, thereby making the gear 1 perform a reciprocating rotation. Through the transmission shaft, the gear 2 and the gear 1 move synchronously, driving the two gears 3 to rotate and then return to their original positions. The cross bar connected to the other end of the spring telescopic rod drives the air pipe to swing up and down reciprocatingly. The steam sprayed from the nozzle of the air pipe directly contacts the surface of the bamboo, so that the steam is evenly distributed in the carbonization furnace, and can quickly heat up the bamboo, which is convenient for the desugaring and carbonization operation.

[0019] S3: During the desugaring and carbonization process, when the tar and resin deposits produced by the bamboo material adhere to the inner wall of the carbonization furnace, according to the cleaning mechanism, while the uniform carbonization mechanism and the gas transmission mechanism are in operation, the gear four is driven to move. When the gas transmission mechanism moves to the top of the carbonization furnace, the gear four drives the cone wheel one to rotate through the belt, and the cone wheel one drives the cone wheel two meshed at the bottom to rotate, so that the turntable rotates synchronously. The support rod on the turntable is squeezed toward the outside of the roller by the elastic force of the spring sheet, so that the support rod is stuck in the multi-angle slot opened on the inner side of the roller. When the turntable rotates, through the support rod, the spring sheet and the multi-angle slot, The roller is driven to rotate continuously, and the roller drives the cleaning belt installed on the upper part to roll continuously. The surface of the cleaning belt rolls and cleans the inner wall of the carbonization furnace. When the gas pipe moves downward, the rotation direction of the gear 4 is reversed, so that the turntable support rod and the spring sheet rotate in the opposite direction. During the process, the support rod is stuck in the multi-angle slot by the force of the spring sheet and then separated due to the rotation force, and the roller will never be driven to rotate. When the gas pipe moves downward, the cleaning belt does not roll. The stationary cleaning belt wipes the inner wall of the carbonization furnace that has just been cleaned. The sewage is left on the inner wall of the carbonization furnace and flows to the bottom of the carbonization furnace through the discharge port;

[0020] S4: After the carbonization is completed, the air outlet valve and the steam valve are closed, and the exhaust valve and the air inlet valve are opened. Dry air is transported into the air inlet pipe through the air inlet valve. The temperature of the input air is the same as the surface temperature of the bamboo in the carbonization furnace to prevent the bamboo from being rapidly cooled and cracked and deformed. When the dry air is blown out from the diffuser, it is diffused to the outside by the diffuser, so that the dry air is diffused and circulated, and the air contacts more bamboo surfaces. The dry air after heat exchange is discharged from the outside of the carbonization furnace through the exhaust valve. After the drying is completed, the furnace cover is opened to pull the bamboo pile out of the carbonization furnace.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. In the present invention, by means of the uniform carbonization mechanism, the gear 2 drives the two spring telescopic rods to rotate in opposite directions through the gear 3, and in the process drives the gas pipe to deliver high-temperature steam to the bamboo pile, and the steam directly contacts the surface of the bamboo, and because the nozzle on the gas pipe is close to the bamboo pile, the steam can penetrate the gap between the bamboo and enter the middle of the bamboo pile, so that the bamboo in the middle of the bamboo pile can be quickly heated, effectively preventing significant temperature differences in different areas of the bamboo pile, and facilitating the improvement of the carbonization efficiency of the bamboo;

[0023] 2. In the present invention, the cleaning mechanism is arranged to drive the cleaning belt to roll and wipe the inner wall of the carbonization furnace while the gas pipe is delivering gas upward. In the process, the tar and resin deposits are removed in combination with the moisture contained on the inner wall of the carbonization furnace. When the gas pipe is running downward, the cleaning belt is kept stationary during the descent process according to the reverse rotation of the gear four, and the cleaning traces are wiped off, which is beneficial to improve the cleanliness of the inner wall of the carbonization furnace and facilitates improving the carbonization output of bamboo;

[0024] 3. In the present invention, by means of the drying mechanism, during the drying process, the air diffuser diffuses the dry air so that the bamboo can be evenly exposed to the dry air, thereby preventing the situation where the humidity of the local bamboo is high during drying and insufficient drying occurs. The dry air can be transported to the middle of the bamboo pile through the through holes, thereby improving the drying efficiency of the bamboo. BRIEF DESCRIPTION OF THE DRAWINGS

[0050] The use method and advantages of the present invention: The desugaring carbonization method of the bamboo desugaring carbonization device has the following working process:

[0051] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 As shown:

[0052] S1: Before carbonization begins, bamboos are placed on the carbonization rack. After the bamboos are placed on the carbonization rack, a bamboo pile is formed. A gap for ventilation is reserved between each bamboo. The carbonization rack is pushed into the carbonization furnace 1 along the feed rail 102, and then the furnace cover 4 is closed, the exhaust valve 10 is closed, and the steam valve 501 is opened. The steam generated in the boiler is transported to the two horizontal pipes 502 through the steam valve 501, and then flows out to the air outlet valve 504 through the hose 503. The air outlet valve 504 is opened, and the steam fills the inside of the gas pipe 505 and continues to extend to the far end, and is sprayed into the inside of the carbonization furnace 1 through the multiple nozzles 506 on the gas pipe 505, so that a high temperature and high humidity desugaring carbonization environment is quickly formed in the carbonization furnace 1;

[0053] S2: Then the driving motor 301 is started, and the output end of the driving motor 301 drives the turntable 302 to rotate continuously. During the process, the side of the turntable 302 connected to the slide rail 305 drives the slide rail 305 to move to one side on the frame 2. During the process, the rack 1 304 drives the gear 1 303 to rotate. After the turntable 302 rotates half a circle, it drives the slide rail 305 to return to its original position, so that the rack 1 304 drives the gear 1 303 to rotate, thereby making the gear 1 303 perform a reciprocating rotation action. Through the transmission shaft 307, the gear 2 601 and the gear 1 303 move synchronously, driving the two gears 3 602 to rotate and then return to their original positions. The cross bar 604 connected to the other end of the spring telescopic rod 603 drives the gas pipe 505 to swing back and forth up and down. The steam sprayed from the nozzle 506 of the gas pipe 505 directly contacts the surface of the bamboo material, so that the steam is evenly distributed in the carbonization furnace 1, and can quickly heat up the bamboo material, which is convenient for the desugaring and carbonization operation.

[0054] S3: During the desugaring and carbonization process, when the tar and resin deposits produced by the bamboo material adhere to the inner wall of the carbonization furnace 1, according to the cleaning mechanism 7, while the uniform carbonization mechanism 6 and the gas delivery mechanism 5 are running, the gear 4 704 is driven to move. When the gas delivery mechanism 5 moves toward the top of the carbonization furnace 1, the gear 4 704 drives the cone wheel 1 706 to rotate through the belt 707, and the cone wheel 1 706 drives the cone wheel 2 708 meshing at the bottom to rotate, so that the turntable 714 rotates synchronously. The support rod 711 on the turntable 714 is squeezed toward the outside of the roller 709 by the elastic force of the spring sheet 712, so that the support rod 711 is stuck in the multi-angle slot 713 opened on the inner side of the roller 709. When the turntable 714 rotates, the support rod 711, the spring sheet 712 and the multi-angle slot 713 are used to move the turntable 714. 3. The roller 709 is driven to rotate continuously. The roller 709 drives the cleaning belt 710 sleeved and installed above it to roll continuously. The surface of the cleaning belt 710 rolls and cleans the inner wall of the carbonization furnace 1. When the gas pipe 505 moves downward, the rotation direction of the gear 4 704 is reversed, so that the support rod 711 and the spring sheet 712 of the turntable 714 rotate in the opposite direction. During the process, the support rod 711 is clamped into the multi-angle clamping groove 713 by the force of the spring sheet 712 and then separated due to the rotation force, and the roller 709 will never be driven to rotate. When the gas pipe 505 moves downward, the cleaning belt 710 does not roll. The stationary cleaning belt 710 wipes the inner wall of the carbonization furnace 1 that has just been cleaned, and the sewage is left on the inner wall of the carbonization furnace 1 and flows to the bottom of the carbonization furnace 1 through the discharge port 103;

[0055] S4: After the carbonization is completed, the air outlet valve 504 and the steam valve 501 are closed, and the exhaust valve 10 is opened, and the air inlet valve 801 is opened, and dry air is transported into the air inlet pipe 802 through the air inlet valve 801. The temperature of the input air is the same as the surface temperature of the bamboo in the carbonization furnace 1 to prevent the bamboo from being cracked and deformed due to rapid cooling. When the dry air is blown out from the air diffuser 803, it is diffused to the outside by the air diffuser 803, so that the dry air is diffused and circulated, and the air contacts more bamboo surfaces. The dry air after heat exchange is discharged from the outside of the carbonization furnace 1 through the exhaust valve 10. After the drying is completed, the furnace cover 4 is opened to pull the bamboo pile out of the carbonization furnace 1.
