Abstract
Description
Technical Field
[0001] This invention relates to the field of biochar preparation technology, specifically to a biochar preparation device based on environmental organisms. Background Technology
[0002] The core of biochar preparation is the biomass pyrolysis reaction. In a closed environment with oxygen isolated or introduced in a small amount, biomass is heated at high temperature and undergoes a series of reactions such as dehydration, removal of volatiles, and carbonization. The remaining solid carbon skeleton gradually forms a porous structure and eventually forms biochar.
[0003] Chinese Patent CN118480362A discloses a biochar preparation device based on environmental organisms, including a carbonization chamber. A material tray is horizontally arranged inside the carbonization chamber, and a material-feeding mechanism is located above the material tray. The material-feeding mechanism includes multiple mounting rods horizontally above the material tray. A horizontal plate is distributed above the front and rear ends of each mounting rod, and a slidable arc-shaped plate is arranged above the horizontal plate. A reciprocating component is arranged between the arc-shaped plate and the horizontal plate. During the material carbonization process, the material can be continuously moved left and right, exposing the pressed material to the outside, facilitating the hot air to fully penetrate the material for carbonization. While this reduces the upward movement of carbonized material to some extent, the material-feeding hook generates resistance when in hard contact with the raw material, easily leading to breakage and splashing of the raw material. This is detrimental to maintaining the raw material's shape and causes it to scatter within the carbonization furnace, making collection and utilization inconvenient. Therefore, we propose a biochar preparation device based on environmental organisms to solve the above problems. Summary of the Invention

[0007] The I-beam frame has two symmetrically arranged side shafts on both sides of its middle section, and a transmission plate is fixedly connected to the top of each side shaft. The top side of the transmission plate abuts against the top of the connecting frame.
[0008] Preferably, a central shaft is rotatably connected to the bottom of each of the two side shafts, and a swing frame is fixedly connected to both sides of the central shaft. A torsion spring is provided between the central shaft and the side shafts, and the torsion spring is used to twist the swing frame to a horizontally horizontal state.
[0009] Preferably, a reversing guide shaft is fixedly installed on one side of the middle part of the I-beam frame. The reversing guide shaft is located below the side of the swing frame and its surface abuts against the swing frame. The reversing guide shaft is used to make the swing frame rotate and swing.
[0010] Preferably, the inside of the swing frame is elastically and slidably provided with a material-pushing shaft, the length of which is shorter than the length of the swing frame, and the outer surface is provided with multiple rods for material-pushing. One side of the material-pushing shaft passes through the swing frame and is fixedly connected to a side frame.
[0011] Preferably, a push block is fixedly installed on the front part of the material rack on one side of the guide shaft. A double-body cross frame fixedly connected to the carbonization furnace is provided above the push block. A first slider is slidably arranged on the double-body cross frame. A first wedge block is slidably arranged on the front part of the first slider block. One side of the surface of the first wedge block abuts against the push block.
[0012] Preferably, a second slider is slidably provided at the end of the double-body crossbar, and a slide plate is slidably provided on both the first slider and the second slider.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0016] 1. In this invention, by setting a material rack with an inclined frame, the transmission swing arm rotates during the movement of the material rack, thereby causing the material feeding shaft to move downward and close to the top of the raw material. During the process, the side wall of the swing frame is blocked by the guide shaft, causing it to rotate 90 degrees around the side shaft, so that the material feeding shaft and several feeding rods are inserted into the raw material. The feeding rods gradually embed into the material in a sweeping posture, avoiding the raw material being forcibly squeezed, protecting the raw material and preventing splashing.
[0017] 2. In this invention, the pushing block and the first inclined wedge block drive the material feeding rod of the feeding shaft to achieve dynamic switching of the feeding area. The feeding rod changes its working position with the cooperation of the side frame and the second long shaft to intermittently form ridges. The gaps formed between several ridges facilitate the flow of high-temperature gas, thereby allowing for a full thermal reaction with the turned-out raw material. This avoids repeated feeding of the same area, reduces dead corners, and improves the efficiency of ensuring that the raw material can fully contact the high-temperature gas.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0029] Example 1: Please refer to Figures 1 to 6 The present invention provides a technical solution: including a carbonization furnace 1, a heating system 2 is provided on the top of the carbonization furnace 1, the output end of the heating system 2 is connected to a gas guide pipe 3, the gas guide pipe 3 is connected to the interior of the carbonization furnace 1 at a distance away from the heating system 2, a feed inlet 4 is provided on the front side of the carbonization furnace 1, a feed baffle 5 is slidably connected to the feed inlet 4, a guide plate 6 is inclinedly provided on the inner wall of the carbonization furnace 1 at the bottom of the feed inlet 4, and a material rack 7 is slidably provided inside the carbonization furnace 1;
[0030] A drive motor 8 is provided on one side of the carbonization furnace 1. The output end of the drive motor 8 is connected to a pulley group 9. The end of the pulley group 9 away from the drive motor 8 passes through the carbonization furnace 1 and is connected to a guide wheel 10. A walking frame 11 is sleeved on the surface of the guide wheel 10 off the axis. The off-axis part of the guide wheel 10 is slidably connected to the inner surface of the walking frame 11. The top and bottom of the walking frame 11 are slidably connected to the carbonization furnace 1.
[0031] A lower swing arm 12 is rotatably installed on one side of the inner wall of the carbonization furnace 1. The connection between the lower swing arm 12 and the carbonization furnace 1 is located below the material rack 7, and the end of the lower swing arm 12 is in frictional contact with the outer wall of the material rack 7. The outer side of the lower swing arm 12 abuts against one side of the connecting frame 13. The connecting frame 13 is slidably connected to the inside of the carbonization furnace 1. An I-beam frame 14 fixedly connected to the carbonization furnace 1 is installed above the material rack 7.
[0032] Two side shafts 15 are symmetrically and slidably arranged on both sides of the middle part of the I-beam frame 14. A transmission plate 16 is fixedly connected to the top of each side shaft 15. One side of the top of the transmission plate 16 abuts against the top of the connecting frame 13.
[0033] The bottom of each of the two side shafts 15 is rotatably connected to a central shaft 17. The two sides of the central shaft 17 are fixedly connected to a swing frame 18. A torsion spring 19 is provided between the central shaft 17 and the side shafts 15. The torsion spring 19 is used to twist the swing frame 18 to a horizontal state.
[0034] A reversing guide shaft 20 is fixedly installed on one side of the middle part of the I-beam frame 14. The reversing guide shaft 20 is located below the side of the swing frame 18 and its surface abuts against the swing frame 18. The reversing guide shaft 20 is used to make the swing frame 18 rotate and swing.
[0035] The swing frame 18 has a flexible and slidable material-pulling shaft 21 inside. The length of the material-pulling shaft 21 is shorter than the length of the swing frame 18, and multiple rods for material-pulling are provided on the outer surface. One side of the material-pulling shaft 21 passes through the swing frame 18 and is fixedly connected to the side frame 22.
[0036] In this embodiment, the operator opens the feed baffle 5 and puts the biomass raw material into the carbonization furnace 1 through the feed port 4. The raw material slides down naturally along the inclined guide plate 6 and finally accumulates on the material rack 7. After the raw material is put in, the feed baffle 5 is closed to form a closed space inside the carbonization furnace 1. The heating system 2 is started and transported to the inside of the carbonization furnace 1 through the gas pipe 3, so that the temperature inside the furnace gradually rises to the temperature required for biomass pyrolysis. At the same time, the drive motor 8 is started. The output end of the drive motor 8 drives the guide wheel 10 to rotate through the pulley group 9. The guide wheel 10 is fitted with a walking frame 11 off the axis. Its rotation drives the walking frame 11 to make reciprocating linear motion under the limit of the inner wall of the carbonization furnace 1. When the walking frame 11 moves forward, it pushes the lower swing arm 12 to rotate around its hinge point with the carbonization furnace 1. The end of the lower swing arm 12 rubs against the outer wall of the material rack 7, causing the lower swing arm 12 to swing downward. During the process, the connecting frame 13 is pulled down.
[0037] In this embodiment, the connecting frame 13 slides downward inside the carbonization furnace 1. Since the top of the connecting frame 13 contacts the transmission plate 16, it drives the transmission plate 16 and the side shaft 15 fixed thereto to slide downward on the I-beam frame 14. The bottom of the side shaft 15 is connected to the swing frame 18 through the central shaft 17. When the side shaft 15 slides, it drives the swing frame 18 to move synchronously. When the swing frame 18 descends to near the reversing guide shaft 20, the reversing guide shaft 20 abuts against the surface of the swing frame 18, forcing the swing frame 18 to rotate and swing around the central shaft 17 to overcome the torque of the torsion spring 19. The swing frame 18 changes from a horizontal state to a vertical state. The material feeding shaft 21 inside the swing frame 18 rotates with the swing frame 18. The material feeding rod on its surface is obliquely inserted into the raw material, which can penetrate deep into the inside of the raw material. As the material feeding frame 7 moves forward, the raw material is ridged and presented in a row, so that the airflow flows through the ridging parts and carries out the heating reaction, which can improve the heating efficiency of the raw material and accelerate the pyrolysis reaction.
[0038] Example 2:
[0039] Please see Figures 7 to 9 The present invention provides a technical solution: a push block 23 is fixedly installed on the front part of the material rack 7 relative to the guide shaft 20. A double-body cross frame 24 fixedly connected to the carbonization furnace 1 is provided above the push block 23. A first slider 25 is slidably arranged on the double-body cross frame 24. A first inclined wedge 26 is slidably arranged on the front part of the first slider 25. One side of the surface of the first inclined wedge 26 abuts against the push block 23.
[0040] The end of the double-body cross frame 24 is slidably provided with a second slider 27. Slide plates 28 are slidably provided on both the first slider 25 and the second slider 27. The top two sides of the slide plate 28 are respectively fixedly connected with a first long shaft 29 and a second long shaft 30. The front part of the second long shaft 30 protrudes from the front side of the first slider 25, and the second long shaft 30 is movably sleeved in the side frame 22.
[0041] A sleeve rod 31 is fixedly connected to one side of the top of the first long shaft 29. A top plate 32 fixedly connected to the carbonization furnace 1 is provided above the double-body cross frame 24. A guide groove 33 is opened through the surface of the top plate 32. The sleeve rod 31 is slidably arranged in the guide groove 33. The guide groove 33 is provided with two sections, one of which is inclined and the other is straight, and the inclined section is shorter than the straight section.
[0042] A fixing member 34 is installed on the double-body cross frame 24 away from the second slider 27. A second inclined wedge block 35 is fixedly connected to the bottom of the fixing member 34. The second inclined wedge block 35 abuts against the first inclined wedge block 26. A return spring 36 is sleeved on the double-body cross frame 24 between the first slider 25 and the fixing member 34.
[0043] In this embodiment, when the material rack 7 moves, the push block 23 on it pushes the first inclined wedge block 26, causing the first slider 25 to slide in the same direction on the double-body cross frame 24. Before this, the side frame 22 rotates with the swing frame 18, and its opening is facing downward and directly framed on the second long shaft 30. During the sliding of the first slider 25, the sleeve rod 31 at the top of the first long shaft 29 slides from the inclined section of the guide groove 33 to the straight section. During the process, it is subjected to force, pulling the first long shaft 29 to drive the slide plate 28 to slide from one side of the first slider 25 to the other side, and simultaneously pulling the second long shaft 30, so that the side frame 22 is pulled outward. The spring between the material feeding shaft 21 and the swing frame 18 is compressed, and several material feeding rods of the material feeding shaft 21 are displaced, so that the material feeding area of the material feeding rod is exchanged.
[0044] In this embodiment, as the material gradually approaches the fixing member 34, the first material feeding operation is nearing completion. The first wedge block 26 contacts the second wedge block 35, causing the first wedge block 26 to be lifted upwards, resulting in the first wedge block 26 breaking contact with the push block 23. Under the elastic force of the return spring 36, the first slider 25 quickly slides back along the double-body crossbeam 24, driving the slide plate 28, the first long shaft 29, and the sleeve rod 31 to reset. The sleeve rod 31 returns to its initial position along the guide groove 33. During the process, when the sleeve rod 31 enters the inclined section from the straight section of the guide groove 33, the slide plate 28 returns to its original position under the spring force of the first slider 25, causing the second long shaft 30 to drive the side frame 22 to return to its original position, causing the feeding shaft 21 to return to its original position. The feeding area of the feeding rod is switched. During the return process of the material rack 7, the material feeding operation is performed again, and several new ridges are created to accelerate the pyrolysis reaction of the uncleared material.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention.
