Description

Technical Field

[0001] This invention relates to a production apparatus and method for ecological filler used in the treatment of tailwater from ecological wetlands, belonging to the field of biomass pyrolysis technology. Background Technology

[0002] Ecological fillers used for treating wastewater from ecological wetlands need to possess high specific surface area, controllable pore structure, and biocompatibility. Therefore, the pyrolysis process in its core preparation requires precise control of the temperature gradient and material residence time. This includes achieving volatile matter removal and preliminary carbonization at a low temperature of 200℃, completing macromolecular cleavage and pore development at a medium temperature of 300-500℃, and promoting aromatization and surface functional group stabilization at a high temperature of 600℃. However, traditional pyrolysis technologies, due to design flaws, struggle to meet these multi-stage synergistic requirements, as detailed below:

[0003] The use of a stationary reactor requires complete evacuation after each material input before restarting, leading to increased daily effective operating time and low equipment utilization. During intermediate feeding, the mixing of new and old materials causes localized overheating (>800℃) or underreaction (<250℃), resulting in increased fluctuations in product carbonization and porosity dispersion. After the high-temperature stage, the residual furnace temperature exceeds 600℃; switching directly to the low-temperature stage results in a 400℃ temperature difference, increasing time costs. Forced water cooling causes a sudden drop in furnace temperature, also increasing the energy consumption of the cooling medium. Single burner temperature control cannot meet the three-stage gradient requirements, resulting in poor pyrolysis stability and a tendency for secondary pyrolysis of lignocellulose raw materials (such as secondary cracking of tar to produce coke), leading to a decrease in the conversion rate of the target product.

[0004] Furthermore, the airflow direction inside the pyrolysis chamber was not dynamically adjusted, resulting in uneven temperature distribution and poor heat conduction, which could easily lead to localized overheating or carbon buildup.

[0005] Therefore, it is necessary to propose a production device and method for ecological filler material used in the treatment of tailwater from ecological wetlands to solve this problem. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a production device and method for ecological filler for the treatment of tailwater in ecological wetlands, which solves the problems of temperature field control mismatch in pyrolysis furnace, energy waste caused by shutdown and cooling, and uneven temperature inside the pyrolysis chamber in the prior art.

[0007] The technical problem to be solved by this invention is achieved by the following technical solution:

[0008] A production device for ecological filler used in the treatment of tailwater from ecological wetlands includes a pyrolysis furnace fixedly installed at one end of a base. Inside the pyrolysis furnace is a partition plate dividing the furnace into a pyrolysis chamber and an installation chamber. The pyrolysis chamber contains a rotatable pyrolysis bin. Multiple partitioned compartments are arranged in a ring around the outer side of the pyrolysis bin. Each partitioned compartment corresponds to a loading and unloading chamber and multiple pyrolysis chambers. Each pyrolysis chamber is connected to a burner system for controlling the temperature of the pyrolysis chamber. An airflow control mechanism is installed inside the installation chamber. Airflow holes are opened at the bottom of the partitioned compartments, corresponding to the airflow control mechanism.

[0009] By adopting the above technical solution, a rotatable pyrolysis chamber is set up inside the pyrolysis chamber. The pyrolysis chamber is further divided into multiple compartments, and the pyrolysis chambers corresponding to the multiple compartments are the charging and discharging chamber and multiple pyrolysis chambers, respectively. The temperature in the multiple pyrolysis chambers is controlled by controlling the heating power of multiple burner systems. At the same time, by rotating the pyrolysis chamber, the material located in the charging and discharging chamber enters the multiple pyrolysis chambers in sequence. The material in the low-temperature pyrolysis chamber enters the medium-temperature pyrolysis chamber, the material in the medium-temperature pyrolysis chamber enters the high-temperature pyrolysis chamber, and the material that has completed pyrolysis in the high-temperature pyrolysis chamber enters the charging and discharging chamber. On the one hand, it realizes the charging / discharging operation without stopping the machine. On the other hand, it can gradually complete the low-temperature, medium-temperature and high-temperature pyrolysis operations without frequently changing the furnace temperature.

[0010] The present invention is further configured such that: a ceramic fiber board is fixedly installed on the inner wall of the partition chamber, and a vacuum interlayer is provided in the inner wall between adjacent partition chambers.

[0011] By adopting the above technical solution, the ceramic fiber board is a high-density ceramic fiber board with a density ≥280kg / m³. 3 It can withstand high temperatures of 800℃. High-density ceramic fiber boards have strong anti-shrinkage properties and reflect heat radiation. Setting high-density ceramic fiber boards can reduce heat transfer between the compartments. Vacuum interlayer is used to reduce the thermal conductivity of the compartments.

[0012] The invention is further configured such that: the airflow control mechanism includes a swing block located directly below the partition support plate; three mounting arms are fixedly connected circumferentially to the outer side of the swing block; a universal ball mount is fixedly connected to the end of each mounting arm; a second universal ball joint is movably connected inside the universal ball mount; guide rails are symmetrically fixedly connected to the top of the second universal ball joint; sliders are slidably connected inside both guide rails; an air nozzle is fixedly connected between the two sliders; the air nozzle communicates with a second air supply pipe; a first universal ball joint is fixedly connected to the outer side of the top of the air nozzle; a universal ball mounting hole is opened inside the partition support plate; the first universal ball joint is movably connected inside the universal ball mounting hole; the airflow hole corresponds to the universal ball mounting hole; an annular groove is opened in the middle of the swing block; a power system is provided in the middle of the annular groove; the power system includes an eccentric wheel disposed inside the annular groove; a first rotating shaft is fixedly connected to one end of the eccentric wheel; a second servo motor is fixedly connected to the middle of the bottom end of the mounting cavity; and the bottom end of the first rotating shaft is fixedly connected to the output shaft of the second servo motor.

[0013] By adopting the above technical solution, the second servo motor drives the first rotating shaft to rotate, which in turn drives the eccentric wheel to rotate. The eccentric wheel inside the annular groove pushes the swing block to perform an eccentric annular motion. The swing block then drives the universal ball mount to perform an eccentric annular motion through the mounting arm. The universal ball mount drives the upper jet nozzle to twist along the universal ball mounting hole through the first universal ball joint, thereby synchronizing the adjustment of the three jet nozzles located at the bottom of the low-temperature pyrolysis chamber, the medium-temperature pyrolysis chamber, and the high-temperature pyrolysis chamber. During this movement, the distance between the bottom of the jet nozzle and the universal ball mount changes continuously as the jet nozzle twists, and the guide rail plate and the slider provide the space for movement. The universal ball mount and the second universal ball joint are used to provide the angle change range during twisting. By changing the angle of the jet nozzle, the angle of the exhaust gas is changed, which is used to adjust the airflow direction of the compartment and ensure the uniformity of the temperature inside the compartment.

[0014] The invention is further configured such that: a ratchet and a ratchet mounting groove are provided above the power system; multiple ratchet teeth are rotatably connected in a ring shape inside the bottom end of the ratchet mounting groove; the outer side of the ratchet teeth is fixedly connected to the ratchet mounting groove by a spring; the top end of the first rotating shaft is fixedly connected to the ratchet; a rotating shaft hole is opened in the inner shaft center of the pyrolysis chamber; a second rotating shaft is rotatably connected inside the rotating shaft hole; the bottom of the second rotating shaft extends into the bearing rotating cylinder and is fixedly connected to the ratchet mounting groove.

[0015] By adopting the above technical solution, the ratchet and ratchet can only cooperate in one direction, which is to avoid the second rotating shaft being driven to rotate due to gravity when the pyrolysis chamber rotates, which in turn drives the first rotating shaft to rotate, thus avoiding damage to the second servo motor; the cooperation of the ratchet and ratchet can also realize the single control of the swing block to make an eccentric circular motion, thereby controlling the change of the nozzle angle, without controlling the movement of the second rotating shaft.

[0016] The invention is further configured such that: a second mounting groove is provided inside the top of the pyrolysis chamber; the top of the second rotating shaft extends into the second mounting groove and is equipped with a packing control mechanism; a packing bearing mechanism is installed below the packing control mechanism; the packing control mechanism includes a driving gear fixedly connected to the top of the second rotating shaft; four driven gears are circumferentially meshed with the driving gear; the driven gears are rotatably connected to the second mounting groove through a third rotating shaft; the bottom of the third rotating shaft extends into the partition chamber and is equipped with a hanging plate; and a hanging hole is provided at the bottom of the hanging plate.

[0017] By adopting the above technical solution, the second rotating shaft drives the driving gear to rotate, which in turn drives the driven gear, the third rotating shaft and the hanging plate to rotate in sequence, and finally drives the packing support mechanism in the four compartments to rotate synchronously. The purpose is to change the position of the material inside the packing support mechanism, and cooperate with the airflow control mechanism to achieve uniform pyrolysis and avoid the problem of insufficient pyrolysis.

[0018] The present invention is further configured such that: the filler bearing mechanism includes a hook, the bottom of the hook is fixedly connected to a bearing column, the outer side of the bearing column is linearly fixedly connected to a plurality of bearing discs, and the bottom of the bearing discs is provided with ventilation holes distributed in a mesh pattern.

[0019] By adopting the above technical solution, the pretreated raw materials are placed in the bearing plate, and the filler bearing mechanism is hung in the hanging hole by hooks to complete the feeding. By opening the mesh-distributed ventilation holes at the bottom of the bearing plate, the material contact area is increased, and incomplete pyrolysis of some materials is avoided.

[0020] The invention is further configured such that: a packing resonance mechanism is installed between the third rotating shaft and the hanging plate; the packing resonance mechanism includes a transmission connecting slider fixed to the bottom of the third rotating shaft and a load-bearing plate fixed to the top of the hanging plate; an inner sliding sleeve is fixedly connected to the top of the vibration generating plate; the transmission connecting slider and the inner sliding sleeve are slidably connected; a first spring is provided between the vibration generating plate and the third rotating shaft; a limiting installation cover is sleeved on the outer side of the hanging plate; the top of the limiting installation cover is fixedly connected to the pyrolysis chamber; a limiting platform is symmetrically fixedly connected inside the limiting installation cover; and notches are provided at both ends of the vibration generating plate.

[0021] By adopting the above technical solution and setting up a packing resonance mechanism, the driven gear drives the third rotating shaft to rotate, and the third rotating shaft drives the inner sliding sleeve to rotate through the transmission connecting slider. The inner sliding sleeve synchronously drives the vibration generating disk and the hanging plate to rotate. When the notch on the vibration generating disk reaches the limiting platform, it is lifted by its interference. When the vibration generating disk moves upward, it drives the inner sliding sleeve to slide along the transmission connecting slider and compresses the first spring. When the next notch passes the limiting platform, the vibration generating disk is unrestrained and accelerates downward under the action of gravity and the elastic force of the first spring, eventually hitting the limiting mounting cover and generating vibration. This vibration is then transmitted by the hanging plate to the packing bearing mechanism, causing the material on the bearing disk to vibrate, effectively changing the material's accumulation pattern and improving the efficiency and quality of the pyrolysis reaction.

[0022] A method for producing an ecological filler material for treating tailwater from ecological wetlands, the method comprising the following steps:

[0023] Step 1: Loading. Open the feeding door and place the pre-treated raw materials into the partitioned compartment of the pyrolysis chamber. At this time, the materials are located in the loading and discharging chamber. Close the feeding door.

[0024] Step 2: Pyrolysis reaction. The pyrolysis chamber rotates 90° to allow the material in the charging and discharging chamber to enter the pyrolysis chamber. The burner system is started. After the first pyrolysis chamber is completed, the pyrolysis chamber rotates 90° to enter the next pyrolysis chamber.

[0025] Step 3: Unloading. After pyrolysis is completed, the pyrolysis chamber rotates the material to the loading and unloading chamber and removes the material.

[0026] The beneficial effects of this invention are as follows: Through the rotating partition design and temperature gradient control of the pyrolysis chamber, this invention achieves a continuous, staged pyrolysis process. The rotating pyrolysis chamber sequentially feeds materials into the low-temperature, medium-temperature, and high-temperature pyrolysis chambers, achieving seamless connection between the loading and unloading chambers and other pyrolysis chambers. Unloading can be completed without stopping the machine, significantly improving equipment utilization. The three burner systems are independently temperature-controlled, combined with PID control to achieve pyrolysis. Furthermore, the continuous constant temperature operation of the three pyrolysis chambers not only solves the problem of increased energy consumption and time costs caused by the need for cooling after the high-temperature section of existing pyrolysis furnaces, but also eliminates concerns about localized overheating caused by the mixing of new and old materials, leading to increased fluctuations in product carbonization and porosity dispersion.

[0027] This invention introduces an airflow control mechanism to dynamically adjust the airflow direction within the pyrolysis chamber, optimize temperature uniformity, change the jet angle, enhance heat conduction, avoid local overheating or carbon buildup, and improve pyrolysis efficiency.

[0042] To facilitate a clear understanding of the technical means, creative features, objectives, and effects of this invention, the invention will be further described below in conjunction with specific illustrations.

[0043] Example 1

[0044] Please see Figures 1 to 4 A production device for ecological filler for ecological wetland tailwater treatment includes a base 1, a pyrolysis furnace 2 fixedly installed at one top end of the base 1, a feeding door 4 installed on one side of the pyrolysis furnace 2, and a partition bearing plate 19 installed inside the pyrolysis furnace 2 to divide the pyrolysis furnace 2 into a pyrolysis chamber 3 and an installation chamber 5.

[0045] The pyrolysis chamber 25 has multiple partitioned compartments 26 arranged in a ring on its outer side. The pyrolysis chamber 3 corresponding to the partitioned compartments 26 is divided into a loading and unloading chamber and multiple pyrolysis chambers. The inner wall of the partitioned compartments 26 is fixedly installed with ceramic fiber boards, which are high-density ceramic fiber boards with a density ≥280kg / m³. 3It can withstand high temperatures of 800℃. The high-density ceramic fiber board has strong anti-shrinkage properties and reflects heat radiation, reducing the heat transfer between each compartment 26. A vacuum interlayer is provided in the inner wall between adjacent compartments 26. The vacuum interlayer is a cavity opened inside the pyrolysis chamber 25 and evacuated to reduce the thermal conductivity of the compartment 26.

[0046] Each pyrolysis chamber is connected to a burner system 6, which is used to control the temperature of the pyrolysis chamber. The burner system 6 is a metal fiber burner, model DWMG-500, which is compatible with natural gas / liquefied petroleum gas and has a combustion temperature range of 100-800℃.

[0047] Multiple pyrolysis chambers are sequentially classified as low-temperature pyrolysis chamber, medium-temperature pyrolysis chamber, and high-temperature pyrolysis chamber. The middle of the low-temperature pyrolysis chamber, medium-temperature pyrolysis chamber, and high-temperature pyrolysis chamber is connected to a heat supply pipe 7. The end of each heat supply pipe 7 is connected to a burner system 6. A burner mounting bracket 18 is installed at the bottom of the burner system 6 and is fixedly connected to the base 1.

[0048] A first mounting groove 20 is provided in the middle of the partition bearing plate 19. A bearing rotating cylinder 21 is rotatably connected inside the first mounting groove 20. A speed-changing gear ring 22 is fixedly connected to the outside of the bearing rotating cylinder 21. One end of the speed-changing gear ring 22 is meshed with an output gear 24. A first servo motor 23 is fixedly connected to the bottom of the partition bearing plate 19. The output shaft of the first servo motor 23 extends into the first mounting groove 20 and is fixedly connected to the shaft of the output gear 24. The top end of the bearing rotating cylinder 21 extends into the pyrolysis chamber 3 and is fixedly connected to the bottom center of the pyrolysis chamber 25.

[0049] The upper part of the low temperature pyrolysis chamber, the medium temperature pyrolysis chamber and the high temperature pyrolysis chamber are connected to exhaust branch pipes 15. The top of the three exhaust branch pipes 15 are connected to the exhaust main pipe 16. The end of the exhaust main pipe 16 is connected to the oil-water separator 14. The oil-water separator 14 is installed on the base 1. An oil storage tank 17 is provided on one side of the oil-water separator 14. The oil storage tank 17 is connected to the oil-water separator 14.

[0050] A heat supply pipe 7 is connected in the middle of the low-temperature pyrolysis chamber, the medium-temperature pyrolysis chamber and the high-temperature pyrolysis chamber. Each heat supply pipe 7 is connected to a burner system 6 at its end. A burner mounting bracket 18 is installed at the bottom of the burner system 6. The burner mounting bracket 18 is fixedly connected to the base 1. The three burner systems 6 are used to control the temperature inside the low-temperature pyrolysis chamber, the medium-temperature pyrolysis chamber and the high-temperature pyrolysis chamber, respectively.

[0051] The lower parts of the low-temperature pyrolysis chamber, the medium-temperature pyrolysis chamber and the high-temperature pyrolysis chamber are connected to a first gas supply pipe 9. The end of the first gas supply pipe 9 is connected to a first inert gas control system 8. The first inert gas control system 8 is installed on the base 1. A first solenoid valve 10 is installed inside the first gas supply pipe 9.

[0052] The interior of the mounting cavity 5 is connected to a second gas supply pipe 12. The end of the second gas supply pipe 12 extends out of the mounting cavity 5 and is connected to a second inert gas control system 11. The second inert gas control system 11 is mounted on the base 1. A second solenoid valve 13 is installed inside the second gas supply pipe 12.

[0053] In this embodiment, a rotatable pyrolysis chamber 25 is set in the pyrolysis chamber 3. The pyrolysis chamber 25 is further divided into four compartments 26, and the pyrolysis chamber 3 corresponding to the four compartments 26 are the loading and unloading chamber, the low-temperature pyrolysis chamber, the medium-temperature pyrolysis chamber, and the high-temperature pyrolysis chamber, respectively. The temperature in the low-temperature pyrolysis chamber, the medium-temperature pyrolysis chamber, and the high-temperature pyrolysis chamber is controlled by controlling the heating power of the three burner systems 6. The first inert gas control system 8, the first solenoid valve 10, the second inert gas control system 11, and the second solenoid valve 13 are used to input inert gas into different chambers according to the pyrolysis scenario, and the air in the furnace is removed to prevent the tree branch particles from oxidizing and burning during the pyrolysis process. The inert gas control system includes components such as a gas storage tank, a pressure reducing valve, a flow meter, and pipelines, which can accurately control the flow rate and pressure of the inert gas.

[0054] Simultaneously, the first servo motor 23 drives the output gear 24 to rotate, and the output gear 24 drives the bearing drum 21 to rotate through the speed-changing gear ring 22. The bearing drum 21 drives the pyrolysis chamber 25 to rotate 90 degrees, so that the material in the charging and discharging chamber enters the low-temperature pyrolysis chamber, the material in the low-temperature pyrolysis chamber enters the medium-temperature pyrolysis chamber, the material in the medium-temperature pyrolysis chamber enters the high-temperature pyrolysis chamber, and the material that has completed pyrolysis in the high-temperature pyrolysis chamber enters the charging and discharging chamber. The material can be taken out by opening the feeding door 4. On the one hand, it realizes the charging / discharging operation without stopping the machine, and on the other hand, it can gradually complete the low-temperature, medium-temperature and high-temperature pyrolysis operations without frequently changing the furnace temperature.

[0055] In one embodiment, the burner system 6 keeps the temperature inside the low-temperature pyrolysis chamber below 200°C, the temperature inside the medium-temperature pyrolysis chamber between 300-500°C, and the temperature inside the high-temperature pyrolysis chamber above 600°C to achieve deep pyrolysis. Each pyrolysis chamber is equipped with a temperature sensor, and an independent feedback loop is formed by a PID controller. The intake air volume and fuel volume in each burner system 6 are independently adjusted through mechanical or pneumatic devices (such as dampers and gas valves).

[0056] Example 2

[0057] Please see Figure 7 , Figure 8 , Figure 9 and Figure 10This embodiment is a further optimization based on embodiment 1. Specifically, the mounting cavity 5 is provided with an airflow control mechanism 28. The airflow control mechanism 28 includes a swing block 36 located directly below the partition support plate 19. Three mounting arms 38 are fixedly connected to the outer circumferential side of the swing block 36. A universal ball mount 35 is fixedly connected to the end of each mounting arm 38. A second universal ball joint 34 is movably connected inside the universal ball mount 35. Guide rail plates 33 are symmetrically fixedly connected to the top of the second universal ball joint 34. Both guide rail plates 33 are slidably connected inside. A slider 32 is connected to the partition 26, and a jet nozzle 30 is fixedly connected between the two sliders 32. The jet nozzle 30 is connected to the second air supply pipe 12. A first universal ball joint 29 is fixedly connected to the outer side of the top of the jet nozzle 30. A universal ball mounting hole 31 is opened inside the partition bearing plate 19. There are three universal ball mounting holes 31, which correspond to the low temperature pyrolysis chamber, the medium temperature pyrolysis chamber and the high temperature pyrolysis chamber respectively. The first universal ball joint 29 is movably connected in the universal ball mounting hole 31. An air flow hole 27 is opened at the bottom of the partition chamber 26, and the air flow hole 27 corresponds to the universal ball mounting hole 31.

[0058] The swing block 36 has an annular groove 37 in the middle, and a power system is provided in the middle of the annular groove 37. The power system includes an eccentric wheel 41 set inside the annular groove 37. One end of the eccentric wheel 41 is fixedly connected to a first rotating shaft 40. A second servo motor 39 is fixedly connected to the bottom center of the mounting cavity 5. The bottom end of the first rotating shaft 40 is fixedly connected to the output shaft of the second servo motor 39.

[0059] In this embodiment, by setting an airflow control mechanism 28, the second servo motor 39 drives the first rotating shaft 40 to rotate, and the first rotating shaft 40 drives the eccentric wheel 41 to rotate. The eccentric wheel 41 inside the annular groove 37 pushes the swing block 36 to perform eccentric annular motion. The swing block 36 then drives the universal ball mounting seat 35 to perform eccentric annular motion through the mounting arm 38. The universal ball mounting seat 35 drives the upper jet nozzle 30 to twist along the universal ball mounting hole 31 through the first universal ball joint 29, so that the three jet nozzles 30 located at the bottom of the low temperature pyrolysis chamber, the medium temperature pyrolysis chamber and the high temperature pyrolysis chamber are adjusted synchronously. During this movement, when the jet nozzle 30 twists, the distance between the bottom and the universal ball mounting seat 35 will change continuously, and the guide rail plate 33 and the slider 32 can provide the space for movement; wherein, the universal ball mounting seat 35 and the second universal ball joint 34 are used to provide the angle change range during twisting;

[0060] By changing the angle of the jet nozzle 30, and thus the angle of the exhaust, the direction of airflow in the compartment 26 is adjusted to ensure the uniformity of the internal temperature of the compartment 26.

[0061] Example 3

[0062] Please see Figures 5 to 10This embodiment is a further optimization based on embodiment 2. Specifically, a ratchet 42 and a ratchet mounting groove 43 are provided above the power system. Multiple ratchet teeth 44 are rotatably connected in a ring shape inside the bottom end of the ratchet mounting groove 43. The outer sides of the ratchet teeth 44 are fixedly connected to the ratchet mounting groove 43 by springs. The top end of the first rotating shaft 40 is fixedly connected to the ratchet 42. A rotating shaft hole 59 is opened in the axial part inside the pyrolysis chamber 25. A second rotating shaft 45 is rotatably connected inside the rotating shaft hole 59. The bottom of the second rotating shaft 45 extends into the bearing rotating cylinder 21 and is fixedly connected to the ratchet mounting groove 43. The ratchet teeth 44 are adapted to the ratchet 42 at the top of the first rotating shaft 40. The top of the pyrolysis chamber 25 has a second mounting groove 48. The top of the second rotating shaft 45 extends into the second mounting groove 48 and is equipped with a packing control mechanism 60. A packing support mechanism 54 is installed below the packing control mechanism 60. The packing control mechanism 60 includes a drive gear 46 fixedly connected to the top of the second rotating shaft 45. The drive gear 46 is circumferentially meshed with four driven gears 47. The driven gears 47 are rotatably connected to the second mounting groove 48 through a third rotating shaft 49. The bottom of the third rotating shaft 49 extends into the partition chamber 26 and is equipped with a hanging plate 52. The bottom of the hanging plate 52 has a hanging hole 53, and the packing support mechanism 54 is installed in the hanging hole 53.

[0063] In this embodiment, when the second servo motor 39 is running, it synchronously drives the ratchet 42 to rotate via the first rotating shaft 40. The ratchet 42 drives the ratchet mounting groove 43 to rotate via the ratchet teeth 44. The ratchet mounting groove 43 drives the drive gear 46 to rotate via the second rotating shaft 45, which in turn drives the driven gear 47, the third rotating shaft 49 and the hanging plate 52 to rotate in sequence. Finally, it drives the packing support mechanism 54 in the four compartments 26 to rotate synchronously. The purpose is to change the position of the material inside the packing support mechanism 54 and cooperate with the airflow control mechanism 28 to achieve uniform pyrolysis and avoid the problem of insufficient pyrolysis.

[0064] The ratchet 42 and ratchet 44 can only cooperate in one direction to prevent the second rotating shaft 45 from rotating under the action of gravity when the pyrolysis chamber 25 rotates, which in turn drives the first rotating shaft 40 to rotate, thus avoiding damage to the second servo motor 39. The cooperation between the ratchet 42 and ratchet 44 can also realize the single control of the swing block 36 to make an eccentric ring motion, thereby controlling the angle change of the jet nozzle 30, without controlling the movement of the second rotating shaft 45.

[0065] Example 4

[0066] Please see Figure 5 This embodiment is a further optimization based on embodiment 3. Specifically, the filler carrying mechanism 54 includes a hook 55, a carrying column 56 is fixedly connected to the bottom of the hook 55, and multiple carrying discs 57 are linearly fixedly connected to the outside of the carrying column 56. The bottom of the carrying disc 57 is provided with ventilation holes 58 distributed in a mesh pattern.

[0067] In this embodiment, the pretreated raw materials are placed in the support plate 57, and the filler support mechanism 54 is hung in the hanging hole 53 by the hook 55 to complete the feeding. By opening the mesh-distributed ventilation holes 58 at the bottom of the support plate 57, the material contact area is increased, and incomplete pyrolysis of some materials is avoided.

[0069] Please see Figure 12 and Figure 13 This embodiment is a further optimization based on embodiment 3. Specifically, a packing resonance mechanism 61 is installed between the third rotating shaft 49 and the hanging plate 52. The packing resonance mechanism 61 includes a transmission connecting slider 62 fixed to the bottom of the third rotating shaft 49 and a vibration generating disk 50 fixed to the top of the hanging plate 52. An inner sliding sleeve 72 is fixedly connected to the top of the vibration generating disk 50. The transmission connecting slider 62 and the inner sliding sleeve 72 are slidably connected. A first spring 65 is provided between the vibration generating disk 50 and the third rotating shaft 49. A limiting mounting cover 51 is sleeved on the outside of the hanging plate 52. The top of the limiting mounting cover 51 is fixedly connected to the pyrolysis chamber 25. A limiting platform 63 is symmetrically fixedly connected inside the limiting mounting cover 51. The limiting platform 63 is inclined and has rollers on its surface to reduce friction. Notches 64 are opened at both ends of the vibration generating disk 50. The length of the notches 64 is greater than the length of the limiting platform 63.

[0070] A support plate 67 is symmetrically fixedly connected to the bottom end of the limiting mounting cover 51. A lever plate 69 is rotatably connected to the top of the support plate 67. The inner side of one end of the lever plate 69 is fixedly connected to the limiting mounting cover 51 through a second spring 70. An impact block 68 is fixedly connected to the inner side of the other end of the lever plate 69. A connecting hole 66 corresponding to the impact block 68 is opened at the bottom of the limiting mounting cover 51. Linkage plates 71 are fixedly connected to both sides of the bottom of the hanging plate 52.

[0071] Since the material is statically piled on the bearing plate 57, prolonged pyrolysis will result in incomplete pyrolysis. Therefore, in this embodiment, a packing resonance mechanism 61 is set up so that the driven gear 47 drives the third rotating shaft 49 to rotate, and the third rotating shaft 49 drives the inner sliding sleeve 72 to rotate through the transmission connecting slider 62. The inner sliding sleeve 72 synchronously drives the vibration generating plate 50 and the hanging plate 52 to rotate. When the notch 64 on the vibration generating plate 50 reaches the limiting platform 63, it is lifted by its interference. When the vibration generating plate 50 moves upward, it drives the inner sliding sleeve 72 to slide along the transmission connecting slider 62 and compresses the first spring 65. When the next notch 64 passes the limiting platform 63, the vibration generating plate 50 is unrestrained and accelerates under the action of gravity and the elastic force of the first spring 65. The material moves downward and eventually impacts the limiting mounting cover 51, generating vibration. This vibration is then transmitted by the hanging plate 52 to the packing support mechanism 54, causing the material on the support plate 57 to vibrate. Simultaneously, the hanging plate 52, which rotates and rises synchronously with the vibration generating plate 50, drives the linkage plate 71 to move upward. The linkage plate 71 presses the lever plate 69, which compresses the second spring 70 and drives the impact block 68 at the other end to move downward. When the linkage plate 71 disengages from the lever plate 69, the lever plate 69, under the elastic force of the second spring 70, drives the impact block 68 to strike the vibration generating plate 50, ultimately transmitting the vibration to the material on the support plate 57, further enhancing the vibration effect. Through the above multi-level linkage mechanism, the material's accumulation pattern is effectively changed, significantly improving the efficiency and quality of the pyrolysis reaction.

[0072] This invention also discloses a method for producing an ecological filler material for treating tailwater from ecological wetlands, the method comprising the following steps:

[0073] Step 1: Loading. Place the pre-treated raw materials into the bearing plate 57, open the feeding door 4, and hang the filling bearing mechanism 54 in the hanging hole 53 through the hook 55. At this time, the material is located in the loading and discharging chamber. Close the feeding door 4.

[0074] Step 2: Pyrolysis reaction - drying and preheating. Start the first servo motor 23. The first servo motor 23 drives the output gear 24 to rotate. The output gear 24 drives the bearing drum 21 to rotate through the speed change gear ring 22. The bearing drum 21 drives the pyrolysis chamber 25 to rotate 90°, so that the material located in the loading and unloading chamber enters the low-temperature pyrolysis chamber. Start the burner system 6, the first inert gas control system 8, the second inert gas control system 11 and the oil-water separator 14. By controlling the burner system 6 corresponding to the low-temperature pyrolysis chamber, drying and preheating at a temperature below 200°C is carried out. Open the first solenoid valve 10 and the second solenoid valve 13 corresponding to the low-temperature pyrolysis chamber to introduce inert gas (such as nitrogen) into the pyrolysis furnace, remove the air in the chamber and prevent the tree branch particles from oxidizing and burning during the pyrolysis process.

[0075] Step 3: Pyrolysis reaction - main pyrolysis. Start the first servo motor 23, and the rotating drum 21 drives the pyrolysis chamber 25 to rotate 90° again, so that the material in the low temperature pyrolysis chamber enters the medium temperature pyrolysis chamber. At the same time, start the corresponding burner system 6 and open the corresponding solenoid valve; remove the air in the chamber and make the temperature in the medium temperature pyrolysis chamber reach 300-500℃.

[0076] Step 4: Pyrolysis reaction - deep cracking. Start the first servo motor 23, and the bearing drum 21 drives the pyrolysis chamber 25 to rotate 90° again, so that the material in the medium-temperature pyrolysis chamber enters the high-temperature pyrolysis chamber. At the same time, start the corresponding burner system 6 and open the corresponding solenoid valve; remove the air in the chamber and make the temperature in the medium-temperature pyrolysis chamber greater than 600°C.

[0077] Step 5: Unloading. Start the first servo motor 23. The bearing drum 21 drives the pyrolysis chamber 25 to rotate 90° again, so that the material in the high temperature pyrolysis chamber enters the loading and unloading chamber. Open the feeding door 4 and remove the packing bearing mechanism 54 from the hanging hole 53.

[0078] In this process, after the pyrolysis chamber 25 rotates 90°, if the material enters the low-temperature pyrolysis chamber from the loading and discharging chamber for the first time, the loading and discharging chamber can repeat the loading and discharging operation until the material loaded for the first time is deeply pyrolyzed and transferred to the loading and discharging chamber. Then, the pyrolyzed material is taken out and a new material to be pyrolyzed is loaded. The unloading and loading operations are repeated continuously thereafter, so as to achieve pyrolysis without stopping the machine.

[0079] Step 6: Product collection. The volatile gases generated by pyrolysis enter the oil-water separator 14 through the exhaust manifold 15 and the exhaust manifold 16 to obtain liquid products. The liquid products are filtered to remove the impurities and fine powder with a particle size of less than 0.3 mm remaining in the crushed wood particles, and bio-oil is obtained and stored in the oil storage tank 17.

[0080] This invention achieves a continuous, staged pyrolysis process through the rotating partition design and temperature gradient control of the pyrolysis chamber 25. The pyrolysis chamber 25 is driven to rotate 90° by the first servo motor 23, sequentially feeding materials into the low-temperature, medium-temperature, and high-temperature pyrolysis chambers. This achieves seamless connection between the "loading and unloading chamber" and other pyrolysis chambers, allowing unloading operations to be completed without stopping the machine, significantly improving equipment utilization. The three pyrolysis chambers—low-temperature, medium-temperature, and high-temperature—operate at a continuous constant temperature, which not only solves the problem of increased energy consumption and time costs caused by the need for cooling after the high-temperature section of existing pyrolysis furnaces, but also eliminates concerns about local overheating caused by the mixing of new and old materials, leading to increased fluctuations in the carbonization degree and increased porosity dispersion of the product.

[0081] Three burner systems 6 are independently temperature controlled (low temperature <200℃, medium temperature 300-500℃, high temperature >600℃), and pyrolysis is achieved by combining PID control; inert gas is precisely injected through the first solenoid valve 10 and the second solenoid valve 13 to isolate air, prevent the oxidation and combustion of tree branch particles, ensure pyrolysis stability, and increase the conversion rate of the target product; the pyrolysis gas enters the oil-water separator 14 through the exhaust manifold 16, and the liquid products (such as tar) are separated from the gas and stored in the oil storage tank 17 to reduce the risk of secondary pollution;

[0082] Furthermore, by introducing an airflow control mechanism 28 to dynamically adjust the airflow direction within the pyrolysis chamber 3, temperature uniformity is optimized. The jet nozzle 30 is linked to the swing block 36 via a universal ball joint and driven by the eccentric wheel 41 to perform eccentric circular motion, changing the jet angle, enhancing heat conduction, avoiding local overheating or carbon buildup, and improving pyrolysis efficiency. The second servo motor 39, combined with the eccentric wheel 41, achieves stepless speed regulation, allowing adjustment of airflow intensity and direction according to material characteristics, suitable for different biomass raw materials (such as branches and straw).

[0083] The ratchet 42 and ratchet 44 work together to drive the second rotating shaft 45, the driving gear 46, and the driven gear 47 to rotate, ultimately causing the hanging plate 52 to drive the packing support mechanism 54 to rotate, achieving dynamic adjustment of the material position and enhancing the uniformity of pyrolysis. The unidirectional meshing design of the ratchet 42 and ratchet 44 ensures that when the pyrolysis chamber 25 rotates, it only drives the supporting rotating drum 21 to rotate in one direction, avoiding damage to the servo motor by the gravitational reaction force. Moreover, the cooperation of the ratchet 42 and ratchet 44 can also achieve single control of the swing block 36 to make an eccentric circular motion, thereby controlling the angle change of the jet nozzle 30, without controlling the movement of the second rotating shaft 45.

[0084] Furthermore, the linearly arranged bearing plates 57 on the bearing column 56 facilitate layered loading of materials, avoiding accumulation that could lead to localized overheating or incomplete pyrolysis; the mesh-distributed ventilation holes 58 form a microchannel structure, increasing the surface area of ​​the material to be heated, promoting rapid exchange between pyrolysis gases and materials, shortening pyrolysis time, accelerating the release of volatiles and heat transfer, and reducing unreacted residues; the hook-type installation simplifies the feeding process and is compatible with the needs of automated production lines.

Those skilled in the art should understand that the present invention is not limited to the above embodiments, and various changes and modifications can be made without departing from the spirit and scope of the invention, all of which fall within the scope of protection claimed by the present invention. The scope of protection of the present invention is defined by the appended claims and their equivalents.
