[0020] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0021] See Figures 1 to 3 The bio-based material preparation system of this invention includes a pretreatment device 1, a conveying device 3, a material cylinder 4, a pyrolysis device 5, and a partition device.

[0022] The pretreatment device 1 has a feed port 13 and a discharge port 14. Raw materials can be added into the pretreatment device 1 through the feed port 13. The pretreatment device 1 is used to compress the raw materials to form material blocks. The material blocks flow out from the discharge port 14 and enter the material cylinder 4.

[0023] In this embodiment, the first end of the conveying device 3 corresponds to the discharge port 14 of the pretreatment device 1, and the second end of the conveying device 3 corresponds to the inlet 58 of the pyrolysis device 5. The material cylinder 4 is mounted on the conveying device 3, so that when the material block flows out from the discharge port 14, it can directly enter the material cylinder 4 at the first end of the conveying device 3. Subsequently, the conveying device 3 can transport the material cylinder 4 located at the first end of the conveying device 3 to the second end of the conveying device 3; and then send it into the pyrolysis device 5 for pyrolysis. In this embodiment, the material cylinder 4 can be directly transported into the interior of the pyrolysis device 5 by the conveying device 3, or the conveying device 3 can transport the material cylinder 4 to the inlet 58, and then transport it into the interior of the pyrolysis device 5 by hoisting or transfer equipment. The conveying device 3 can be a belt conveyor or a plate chain conveyor.

[0024] The partition device has a discharge port. Both the discharge port of the partition device and the discharge port 14 of the pretreatment device 1 correspond to the material cylinder 4 located at the first end of the conveying device 3, so that the partitions entering the material cylinder 4 from the discharge port and the material blocks entering the material cylinder 4 from the discharge port 14 are stacked. In this embodiment, the partition device stores multiple partitions. When the partitions fall from the discharge port, they can directly enter the material cylinder 4 at the first end of the conveying device 3. Thus, in this embodiment, the stacking arrangement of the material blocks and partitions can be achieved by controlling the falling time of the material blocks and the falling time of the partitions.

[0025] For example, material blocks and partitions are stacked alternately in the material cylinder 4 in a one-to-one correspondence. At this time, a partition is attached to the top and bottom of each material block, and a material block is attached to the top and bottom of each partition.

[0026] For example, after multiple material blocks are dropped into the material cylinder 4, a partition is dropped in, and the material is dropped into the material cylinder 4 alternately. At this time, two, three or four material blocks can be set between two adjacent partitions.

[0027] In application, the stacking arrangement of partitions and material blocks can be determined based on the thickness of the material blocks.

[0028] The bio-based material preparation system of this invention can utilize raw materials such as wheat straw, corn cobs, and sawdust to prepare bio-based materials. This embodiment can optimize the process flow, reduce the amount of chemical reagents used, improve the diversity of product properties, enhance pyrolysis efficiency and effect, and achieve large-scale, efficient production, thereby meeting the demand for efficient and environmentally friendly technologies in the field of agricultural waste resource utilization.

[0029] In some embodiments, the pretreatment device 1 includes a crushing component 11 and a forming component 12 connected to each other. The inlet of the crushing component 11 is a feeding port 13, and the outlet of the forming component 12 is a discharging port 14. The crushing component 11 is used to crush the raw material, and the forming component 12 is used to compress the crushed raw material to form a block.

[0030] The crushing component 11 is a material crusher that crushes raw materials such as wheat straw, corn cobs, and sawdust into roughly uniform particle sizes. The forming component 12 is an extrusion molding machine that compresses the crushed material into round cake-shaped blocks, thereby increasing the density of the blocks, facilitating pyrolysis, and improving the performance of the bio-based materials after pyrolysis.

[0031] In some embodiments, the partition device includes a compartment 21, a slide 22, and a plate feeding assembly. The slide 22 is connected to the outlet at the lower part of the compartment 21. The end of the slide 22 away from the compartment 21 is configured as a plate outlet 23. The plate feeding assembly is located at the lower part of the compartment 21 and is used to push the partitions in the compartment 21 into the slide 22.

[0032] The silo 21 can be a generally cylindrical silo, with the partitions being generally disc-shaped or elongated. The slide 22 is an inclined slide 22, which guides the partitions to ensure they can slide into the material cylinder 4. The plate feeding assembly can be a cylinder, an electric push rod, or a hydraulic cylinder. For example, the plate feeding assembly includes an electric push rod, with a push plate 241 at the actuating end of the electric push rod. The push plate 241 can push the partitions from the outlet of the silo 21 into the slide 22. The plate feeding assembly is positioned opposite to the outlet of the silo 21, thereby pushing the lowest partition of the silo 21 into the slide 22 and sliding it along the slide 22 into the material cylinder 4.

[0033] In this embodiment, the timing of the feeding assembly's movement can be coordinated with the material block's drop to achieve the stacking arrangement of the material block and partition plate within the material cylinder 4.

[0034] In this embodiment, the partition is made of a thermally conductive material. Similarly, the barrel 4 is also made of a material with good thermal conductivity. Thus, after the barrel 4 is fed into the pyrolysis device 5, the heat conduction of the barrel 4 and the partition can be used to heat the material block, so that the material block is heated evenly, improving the pyrolysis efficiency, achieving efficient pyrolysis, avoiding the problem of excessive differences in the degree of pyrolysis in different areas, and facilitating mass production operations.

[0035] The partition plate in this embodiment has through holes, which facilitates heat transfer and the discharge of pyrolysis gases, thereby improving its practicality.

[0036] In some embodiments, the pyrolysis apparatus 5 includes a pyrolysis chamber 51, a turntable 52, a heating component 55, and a first driver. The turntable 52 and the heating component 55 are disposed in the pyrolysis chamber 51. The first driver is used to drive the turntable 52 to rotate. The turntable 52 is used to drive the material cylinder 4 located above it to rotate in the pyrolysis chamber 51. The turntable 52 and the heating component 55 are arranged spaced apart from each other in the circumferential direction of the turntable 52.

[0037] The pyrolysis chamber 51 can be a relatively sealed chamber. The turntable 52 is located at the bottom of the inner cavity of the pyrolysis chamber 51. The turntable 52 can rotate under the drive of the first driver, which can be a motor. When the material cylinder 4 is placed on the turntable 52, the turntable 52 can drive the material cylinder 4 to rotate inside the pyrolysis chamber 51. When the material cylinder 4 is close to the heating component 55, the material cylinder 4 is in a heating state. When the material cylinder 4 moves in the area adjacent to the heating component 55, the material cylinder 4 is in a high-efficiency pyrolysis state. When the material cylinder 4 moves towards the outlet of the pyrolysis chamber 51, the material cylinder 4 can be cooled down.

[0038] This embodiment can optimize the pyrolysis process of the material block in the barrel 4 by controlling the rotation speed of the turntable 52, improve the pyrolysis efficiency, and make the heating, pyrolysis and cooling of the material block proceed in an orderly manner, which is convenient for large-scale production.

[0039] In the rotation direction of the turntable 52, the heating component 55 is located between the inlet 58 and the outlet of the pyrolysis chamber 51, with the inlet 58 and the pyrolysis station forming a heating section and the pyrolysis station and the outlet forming a cooling section.

[0040] This embodiment can also optimize the position of the heating component 55 so that the distance between the heating component 55 and the inlet 58 determines the stroke of the heating section, the size of the area covered by the heating component 55 determines the stroke of the pyrolysis section, and the distance between the heating component 55 and the outlet determines the stroke of the cooling section. In this way, the central angles corresponding to the heating section, pyrolysis section and cooling section in the pyrolysis chamber 51 can be adjusted, and the time of each process interval can be reasonably adjusted.

[0041] In this embodiment, the heating component 55 can be an electric heater. The heating component 55 can be located in a circumferential section of the inner wall of the pyrolysis chamber 51 to create a highly efficient pyrolysis zone.

[0042] In some embodiments, the turntable 52 is provided with a plurality of positioning components 53, which are used to support the material cylinder 4 and limit the position of the material cylinder 4 relative to the turntable 52. The positioning components 53 can constrain the position of the material cylinder 4 to prevent the material cylinder 4 from slipping off the turntable 52.

[0043] Furthermore, the positioning assembly 53 includes a rotating frame 531, which is rotatably connected to the turntable 52. The upper part of the rotating frame 531 has a positioning part 533, and the bottom of the material cylinder 4 cooperates with the positioning part 533. The rotating frame 531 can rotate on the turntable 52, and drive the material cylinder 4 to rotate. At this time, a second driver can be set in the positioning assembly 53 to drive the rotating frame 531 to rotate. The second driver can be a motor, which drives the rotating frame 531 to rotate relative to the turntable 52.

[0044] As the turntable 52 rotates, the rotating frame 531 drives the material cylinder 4 to rotate, thereby allowing the material cylinder 4 to revolve and rotate, improving the sufficiency of heating during pyrolysis and enhancing the pyrolysis effect.

[0045] Optionally, the positioning assembly 53 further includes a spring 532. The rotating frame 531 has a support shaft in the middle, and the spring 532 is sleeved on the support shaft. The first end of the spring 532 abuts against the rotating frame 531, and the second end of the spring 532 abuts against the turntable 52. The spring 532 can support the outer circumferential edge of the rotating frame 531, preventing the rotating frame 531 from wearing due to lateral force, thus improving the service life of the component.

[0046] In some embodiments, the pyrolysis apparatus 5 includes an adjustment component 54, which is disposed on the upper part of the pyrolysis chamber 51. The area of ​​the pyrolysis chamber 51 near the heating component 55 is configured as a pyrolysis station. The adjustment component 54 is located above the pyrolysis station and has a clamping component 544 for clamping the material cylinder 4 at the pyrolysis station to drive the material cylinder 4 to rotate or vibrate.

[0047] When the material cylinder 4 moves to the pyrolysis station, the turntable 52 can stop moving for a period of time. The clamping component 544 in the adjustment component 54 can clamp the material cylinder 4 and drive the material cylinder 4 to rotate or shake, so that the internal material is more regular and avoids large gaps between the material block and the partition, which would lead to problems such as poor heat transfer performance.

[0048] The clamping component 544 can be a claw or a clamp, etc. When the clamping component 544 is activated, it can clamp the edge of the material cylinder 4, thereby driving the material cylinder 4 to move.

[0049] The adjusting assembly 54 includes a housing 541, a third actuator 542, and a fourth actuator 543. The housing 541 is connected to the pyrolysis chamber 51 via the third actuator 542 to drive the housing 541 to move vertically. The third actuator 542 can be a cylinder, an electric push rod, or a hydraulic cylinder. When the clamping component 544 clamps the material cylinder 4, the third actuator 542 retracts, which can drive the material cylinder 4 to detach from the turntable 52, facilitating vibration and rotation. The fourth actuator 543 is connected between the housing 541 and the clamping component 544 to drive the clamping component 544 to rotate or vibrate. The fourth actuator 543 can be a common motor or a vibration motor. When it is a common motor, it can drive the clamping component 544 and the material cylinder 4 to rotate; when it is a vibration motor, it can drive the clamping component 544 and the material cylinder 4 to vibrate.

[0050] In this embodiment, the pyrolysis chamber 51 is provided with an air inlet pipe 56 and an exhaust pipe 57. The air inlet pipe 56 is used to deliver protective gas into the pyrolysis chamber 51. When the pyrolysis device 5 is started up, protective gas can be introduced into the pyrolysis chamber 51 to prevent the raw materials from oxidizing. After the pyrolysis gas is stably discharged, the gas generated by pyrolysis can be extracted through the exhaust pipe 57 to ensure pressure balance and efficient pyrolysis.

[0051] The bio-based material preparation method of this invention utilizes the bio-based material preparation system of any of the above embodiments to prepare bio-based materials. The bio-based material preparation method includes: S1. Clean the biological raw materials.

[0052] S2. The biological raw materials are fed into the pretreatment device 1 to be crushed and compressed into blocks.

[0053] In the wheat straw collection and pretreatment stage, waste wheat straw from the field is mechanically collected and sent to a washing device to remove surface impurities. The washed wheat straw is then conveyed to a crushing assembly 11, where high-speed rotating blades cut the straw into fine particles of uniform size. The crushed particles are then compressed in a compression assembly, where a compression mold presses the particles into blocks to improve heat transfer efficiency and material stability during subsequent pyrolysis.

[0054] S3. Feed the material block and the partition in the partition device into the material cylinder 4, and stack the material block and the partition.

[0055] After the material blocks enter the feed cylinder 4, the baffle assembly 2 begins operation. The push rod of the plate feeding component 24 drives the push plate 241 to push out the porous thermally conductive baffles one by one from the plate bin 21 and send them into the feed cylinder 4. While receiving the material blocks, the baffles are inserted into the feed cylinder 4, forming a structure where the material blocks and baffles are arranged alternately. This design ensures that heat is evenly distributed inside the feed cylinder 4 during pyrolysis, avoiding problems such as localized overheating or incomplete pyrolysis.

[0056] S4. The conveying device 3 transports the material cylinder 4, containing material blocks and partitions, into the pyrolysis device 5. When the material cylinder 4 is delivered to the pyrolysis chamber 51 by the conveying device 3, the positioning component 53 on the turntable 52 can fix the material cylinder 4, for example, by limiting the material cylinder 4 through structures such as slots and positioning posts, and the spring 532 can improve the stability of the material cylinder 4 during rotation. The turntable 52 is driven by a motor and rotates intermittently at set time intervals, so that each material cylinder 4 approaches the heating component 55 one by one. After the heating component 55 is started, it maintains the temperature in the pyrolysis chamber 51 between 300℃ and 600℃. This temperature range can effectively promote the pyrolysis reaction of raw materials such as wheat straw, while avoiding excessive carbonization that would lead to a decline in product performance. S5. Start the rotation of the turntable 52 in the pyrolysis device 5. The temperature in the pyrolysis chamber 51 of the pyrolysis device 5 is 300 degrees Celsius to 600 degrees Celsius. The material block in the material cylinder 4 is pyrolyzed in the pyrolysis chamber 51 and forms bio-based material.

[0057] S6. After pyrolysis is completed, remove the cylinder 4 containing the pyrolyzed material blocks.

[0058] During pyrolysis, a protective gas is continuously introduced into the pyrolysis chamber through the inlet pipe to prevent oxidation reactions and ensure the purity and performance of the bio-based materials. The exhaust pipe promptly discharges gases generated during pyrolysis, maintaining the pressure within the chamber within a safe range. After pyrolysis, doors are installed at the inlet and outlet. These doors are opened by hydraulic cylinders or other actuators. After the material is removed from the chamber, it can be transported away via a separately arranged conveyor system, transferring the pyrolysis products to subsequent processing steps. This invention achieves flexible switching between heating and cooling of the material cylinder through the intermittent rotation of the turntable, while the vibration function of the regulating component significantly improves the heat transfer efficiency and material decomposition effect during pyrolysis. The porous thermal conductivity design of the baffle further optimizes the temperature distribution during pyrolysis, ensuring the consistency of product performance. Overall, this invention reduces the complexity of manual operation, improves the automation level of the system, and provides technical support for large-scale, efficient production.
