Abstract
Description
Technical Field
[0001] This invention relates to the field of biochar production equipment technology, specifically to a drum cooling charcoal discharge device. Background Technology
[0002] A carbonization furnace is a device used to carbonize combustible raw materials (wood, straw, sawdust, etc.). It employs the principle of dry distillation carbonization, heating and decomposing the raw materials in the absence of air to achieve carbonization. After carbonization, biomass char is at a high temperature and requires cooling. Conventional cooling methods for biomass char generally include natural cooling and water spraying. Natural cooling involves directly exposing the biomass char to air, which is time-consuming and inefficient. Water spraying involves directly spraying water onto the biomass char to lower its temperature, but this method results in a high moisture content, significantly reducing the quality of the biomass char.
[0003] To avoid the drawbacks of the aforementioned biochar cooling methods, existing technologies also include separate heat exchange methods: such as... Figure 1 As shown, the biomass char slides through the double-layer drum 20. The circulating water pump 70 controls the pumping of cool water from the circulating water tank 80 to the space between the outer and inner cylinders of the double-layer drum 20. This allows the biomass char to exchange heat with the cooling water through the inner cylinder of the double-layer drum 20, thereby reducing the temperature of the biomass char. The resulting hot water is then piped into the cooling tower 90 for heat release and cooling. The water cooled by the cooling tower 90 then flows back into the circulating water tank 80, thus achieving water circulation.
[0004] However, this approach still has its shortcomings:
[0005] First, when biochar slides inside the drum, the fixed part of the biochar contacts the inner wall of the drum for heat exchange, while other parts of the biochar may not be in contact with the inner wall of the drum, which can easily lead to uneven heat exchange and reduce the cooling effect of the biochar.
[0006] Secondly, biochar varies in size. Small-sized biochar is easy to cool down to the required temperature, while large-sized biochar is prone to insufficient heat exchange, resulting in unqualified cooling of large-sized biochar and thus reducing its cooling effect. Summary of the Invention
[0007] This invention provides a drum cooling charcoal output device, which aims to solve the problems in related technologies where various parts of the biomass charcoal cannot contact the inner wall of the drum for heat exchange during cooling, and where heat exchange is easily inadequate for large-sized biomass charcoal.
[0008] The drum cooling and carbon discharge device of the present invention includes a support and further includes:
[0009] A double-layer drum is rotatably mounted on the support, including an inclined inner cylinder and an outer cylinder fixed to the outside of the inner cylinder, with a water passage cavity formed between the inner cylinder and the outer cylinder;
[0010] A water conveying mechanism, connected to the water passage cavity, is used to allow cooling water to flow through the water passage cavity;
[0011] Multiple processing mechanisms, each of which includes a lifting mechanism, a carbon blocking component, and an impact mechanism disposed within an inner cylinder, wherein the carbon blocking component has a channel;
[0012] When the inner cylinder rotates, the lifting mechanism can lift the biomass char inside the inner cylinder. Biomass char smaller than the channel can pass through the channel, while biomass char larger than the channel is blocked by the char-blocking component. The impact mechanism can impact the biomass char larger than the channel.
[0013] In operation, the double-layer drum is rotated, and the water supply mechanism introduces water into the water passage chamber. Biomass char is added to the inner cylinder and moves downwards along the inclined inner cylinder. The biomass char exchanges heat with the water through the inner cylinder, cooling it. The rotation of the inner cylinder drives the lifting mechanism, char-blocking components, and impact mechanism to rotate synchronously. The lifting mechanism elevates the biomass char. When the biomass char reaches the top of the inner cylinder, it detaches from the lifting protrusions under its own weight, thus achieving the throwing and turning of the biomass char. This ensures that all parts of the biomass char fully contact the inner wall of the cylinder for heat exchange. This improves the uniformity of heat exchange in biomass char. Biomass char smaller than the channel can pass through the channel, while biomass char larger than the channel is blocked upstream of the char-blocking ring by the char-blocking component. This prolongs the residence time of large-sized biomass char in the inner cylinder, increasing the heat exchange time and allowing for sufficient heat exchange between the large-sized biomass char and the inner cylinder. At the same time, the impact mechanism can impact the large-sized biomass char, causing it to break into smaller-sized biomass char, ensuring that the biomass char undergoes proper heat exchange and thus achieves qualified cooling, thereby improving the heat exchange effect between the biomass char and the inner wall of the inner cylinder.
[0014] Preferably, the lifting mechanism includes lifting bars disposed on the inner wall of the inner cylinder, the lifting bars having multiple lifting protrusions, and when the lifting bars rotate with the inner cylinder, the lifting protrusions can drive the biochar to be lifted first and then released.
[0015] The rotation of the inner cylinder can drive the lifting mechanism to rotate synchronously. The lifting protrusions on the lifting mechanism can lift the biomass char inside the inner cylinder, so that the biomass char can be lifted up and turned inside the inner cylinder, thereby allowing all parts of the biomass char to come into contact with the inner wall of the inner cylinder for heat exchange.
[0016] Preferably, the inner wall of the inner cylinder is provided with an annular groove, and the lifting bar is made of elastic material. The lifting bar abuts against the inner wall of the annular groove. When the inner cylinder rotates, the friction between the inner cylinder and the lifting bar can drive the lifting bar to rotate synchronously.
[0017] When it is necessary to replace the lifting bar, apply force to bend the lifting bar, which can remove the lifting bar from the inner wall of the annular groove. Then apply force to bend the new lifting bar, keep the bent new lifting bar in the annular groove, and then release it to complete the installation of the new lifting bar, which improves the convenience of lifting bar replacement.
[0018] Preferably, the carbon-blocking component includes a carbon-blocking ring, on which a connecting strip is fixedly mounted. The connecting strip is fixedly mounted on the inner wall of the inner cylinder, and the channel is formed by the carbon-blocking ring, the inner wall of the inner cylinder, and the space between each pair of adjacent connecting strips.
[0019] Biochar larger than the channel size will be blocked upstream of the char-blocking ring, increasing its residence time in the inner cylinder and improving the heat exchange effect.
[0020] Preferably, the impact mechanism includes a guide rod fixed to the inner wall of the inner cylinder, a sliding seat slidably provided on the outer surface of the guide rod with a single degree of freedom, and impact heads fixed at the top and bottom of the sliding seat, with each impact head positioned upstream of the carbon-blocking ring.
[0021] As the inner cylinder rotates, it drives the guide rod to rotate synchronously. When the guide rod rotates, it drives the sliding seat to rotate. Whenever the guide rod tends to be vertical, the sliding seat and the impact head can slide down the guide rod under their own weight. The impact head located at the bottom falls to the upstream position of the carbon-blocking ring and impacts the large-sized biomass char blocked at the upstream position of the carbon-blocking ring, causing the large-sized biomass char to be impacted into smaller-sized biomass char, which then continues to move through the channel, improving the heat exchange effect between the biomass char and the inner wall of the inner cylinder.
[0022] Preferably, the guide rod is triangular prism-shaped, and the sliding seat has a triangular hole that matches the guide rod.
[0023] Preferably, two limiting blocks are also fixed on the guide rod. The two limiting blocks are located on both sides of the sliding seat. The sliding seat can fall on the limiting blocks when it moves down. When the sliding seat contacts the limiting blocks, there is a gap between the impact head and the lifting protrusion.
[0024] The limiting block can limit the maximum distance the sliding seat can move downward, preventing the impact head from directly colliding with the lifting protrusion and causing damage.
[0025] Preferably, it also includes a feeding structure located at the highest end of the inner cylinder. The feeding structure includes a sealing plate fixed on the support. The sealing plate is rotatably connected to the inner cylinder. A feeding chute is fixed on the sealing plate and extends into the interior of the inner cylinder.
[0026] Preferably, it also includes a discharge hood located at the lowest end of the inner cylinder. The discharge hood is fixed on the support and is rotatably connected to the outer surface of the inner cylinder. A discharge port is provided below the discharge hood.
[0027] Preferably, the water conveying mechanism includes two water conveying components, which are respectively located at both ends of the double-layer roller; in each water conveying component, the water conveying component includes a connecting frame fixed on the frame body, the connecting frame has a pipe joint, the central axis of the pipe joint is collinear with the central axis of the double-layer roller, the pipe joint is rotatably connected to a water conveying pipe, the end of the water conveying pipe away from the pipe joint is fixed on the inner cylinder, the water conveying pipe passes through the inner cylinder and communicates with the water conveying cavity.
[0028] The beneficial effects of this invention are:
[0029] 1. When biomass char passes through the inner cylinder, the rotation of the inner cylinder drives the lifting mechanism, char blocking parts and impact mechanism to rotate synchronously. The lifting mechanism can lift and then throw the biomass char, realizing the tumbling effect of the biomass char, so that all parts of the biomass char can fully contact the inner wall of the inner cylinder for heat exchange, thereby improving the uniformity of heat exchange of the biomass char.
[0030] 2. Biomass char with a size larger than the channel is blocked by the char-blocking component, which prolongs the residence time of the large-sized biomass char in the inner cylinder and increases the heat exchange time, so as to fully exchange heat between the large-sized biomass char and the inner cylinder. At the same time, the impact mechanism can impact the blocked biomass char, causing the large-sized biomass char to be impacted into smaller-sized biomass char, so that the biomass char can be heat exchanged in place, thereby making the biomass char cool down to a qualified level and improving the heat exchange effect between the biomass char and the inner wall of the inner cylinder.

[0042] 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 of ordinary skill in the art without creative effort are within the scope of protection of the present invention.
[0043] like Figures 2 to 9As shown, the drum cooling charcoal discharge device of the present invention includes a support 10 for supporting the drum cooling charcoal discharge device of the present invention. An inclined double-layer drum 20 is rotatably connected to the support 10. A feeding structure 30 extends into the highest end of the double-layer drum 20. A discharge hood 40 is fitted into the lowest end of the double-layer drum 20. A water conveying mechanism 50 is connected to the support 10. Multiple processing mechanisms 60 are arranged inside the double-layer drum 20 to process the biomass charcoal inside the double-layer drum 20 so that the biomass charcoal inside the double-layer drum 20 can fully exchange heat with the double-layer drum 20. The biomass charcoal can be added into the double-layer drum 20 through the feeding structure 30, and the heat of the biomass charcoal can be transferred to the double-layer drum 20. The water conveying mechanism 50 can flow water through the double-layer drum 20 to cool the double-layer drum 20.
[0044] refer to Figures 2 to 4 As shown, the support 10 includes a frame 11, with a movable wheel 12 installed at the bottom of the frame 11. When the support 10 is pushed or pulled, the movable wheel 12 can roll on the ground to facilitate the movement of the entire device. At least four bearing seats 13 are installed on the frame 11, and the four bearing seats 13 are distributed on the frame 11. Each bearing seat 13 is rotatably connected to a support roller 14. The support rollers 14 support the two sides of the double-layer roller 20 respectively to provide stable support for the double-layer roller 20. When the double-layer roller 20 rotates, the support rollers 14 can roll along with the rotation of the double-layer roller 20 to reduce the friction between the support 10 and the double-layer roller 20. A rotation drive device 15 is installed on the frame 11, which provides power to drive the double-layer roller 20 to rotate.
[0045] For example, the rotation drive device 15 includes a geared motor 151 fixedly mounted on the frame 11. An abutment roller 152 is fixedly mounted on the output end of the geared motor 151. The abutment roller 152 abuts against the outer surface of the double-layer roller 20. Driving the geared motor 151 can drive the abutment roller 152 to rotate. The rotation of the abutment roller 152 can drive the double-layer roller 20 to rotate through the friction between the abutment roller 152 and the double-layer roller 20, thereby realizing the rotation function of the double-layer roller 20.
[0046] refer to Figure 2 , Figure 3 and Figure 5As shown, the double-layer roller 20 includes an inner cylinder 21, which is inclined and has an angle of 15-75 degrees with the horizontal plane. An outer cylinder 22 is welded to the outer surface of the inner cylinder 21. The inner cylinder 21 and the outer cylinder 22 form a water passage cavity 23, which is connected to a water conveying mechanism 50. The water conveying mechanism 50 can pass water into the water passage cavity 23. When the water passes through the water passage cavity 23, it can exchange heat and cool the double-layer roller 20. At least one limiting ring 24 is welded to the outer surface of the outer cylinder 22. A limiting groove 25 is integrally formed on the limiting ring 24. At least one support roller 14 is restricted to roll within the limiting groove 25. By restricting the support roller 14 through the limiting groove 25, the double-layer roller 20 can be prevented from moving along the axial direction of the double-layer roller 20, thereby ensuring the stable cooperation between the double-layer roller 20 and the support 10 and preventing the double-layer roller 20 from being misaligned.
[0047] refer to Figure 2 , Figure 3 and Figure 6 As shown, the feeding structure 30 includes a sealing plate 31 welded to the frame 11. The sealing plate 31 is rotatably connected to the inner wall of the inner cylinder 21 via a bearing. A feeding chute 32 is welded onto the sealing plate 31. It should be noted that the feeding chute 32 has a hopper section 321 and an extension section 322 communicating with the hopper section 321. The hopper section 321 is funnel-shaped with a larger top and a smaller bottom. The extension section 322 is welded to the sealing plate 31 and extends into the interior of the inner cylinder 21. When biomass char is added to the hopper section 321 on the feeding chute 32, the biomass char can fall into the inner cylinder 21 through the extension section 322, thus realizing the feeding of biomass char.
[0048] refer to Figure 2 , Figure 3 and Figure 7 As shown, the discharge hood 40 is welded to the support 10. The discharge hood 40 is rotatably connected to the outer surface of the lowest end of the inner cylinder 21 through a bearing. The discharge port 41 is opened at the bottom of the discharge hood 40. After passing through the inner cylinder 21, the biomass char is discharged from the lowest end of the inner cylinder 21 and falls into the discharge hood 40. Finally, it is discharged directionally from the discharge port 41 at the bottom of the discharge hood 40.
[0049] refer to Figure 2 , Figure 3 , Figure 6 and Figure 7As shown, the water conveying mechanism 50 includes two water-passing assemblies, located at opposite ends of the double-layer drum 20. Each water-passing assembly includes a connecting frame 51 welded to the frame 11. The connecting frame 51 has a pipe connector 52, the central axis of which is collinear with the central axis of the double-layer drum 20. A water-passing pipe 53 is rotatably connected to the inner wall of the pipe connector 52 via a sealed bearing. The end of the water-passing pipe 53 away from the pipe connector 52 is welded to the inner cylinder 21, and the water-passing pipe 53 penetrates the inner cylinder 21 and communicates with the water-passing cavity 23. When the inner cylinder 21 rotates, the water-passing pipe 53 rotates synchronously with it, and also rotates with the pipe connector 52 via the sealed bearing. The two pipe connectors 52 serve as the inlet and outlet, respectively, connecting to the external water circulation system. The two water-passing pipes 53 are rotatably connected to the sealing plate 31 and the discharge hood 40 via bearings.
[0050] For example, the external water circulation system includes a circulating water pump, a cooling tower, and a circulating water tank. The outlet of the cooling tower is connected to the circulating water tank, and the circulating water tank is connected to the inlet of the circulating water pump through a pipe. The outlet of the circulating water pump is connected to a pipe joint 52 through a pipe, and another pipe joint 52 is connected to the cooling tower through a pipe. In this way, the circulating water pump can pump the cooled water in the circulating water tank into a pipe joint 52, and then inject it into the water passage chamber 23 through a water passage pipe 53 connected to the pipe joint 52, so that the water exchanges heat with the double-layer drum 20. The hot water then flows to the other pipe joint 52 through another water passage pipe 53. Subsequently, the hot water is passed through a pipe into the cooling tower for heat release and cooling. The water cooled by the cooling tower flows back into the circulating water tank, realizing the recycling of water and achieving the purpose of saving water resources.
[0051] refer to Figure 3 , Figures 6 to 9 As shown, each processing unit 60 includes a lifting mechanism 61, a carbon blocking component 62, and an impact mechanism 63 installed on the inner wall of the inner cylinder 21. During the rotation of the inner cylinder 21, the lifting mechanism 61 can lift the biomass char inside the inner cylinder 21, so that the biomass char can be tumbled inside the inner cylinder 21, thereby allowing all parts of the biomass char to contact the inner wall of the inner cylinder 21 for heat exchange. The carbon blocking component 62 can block large-sized biomass char, so that more biomass char stays in the inner cylinder 21, increasing the contact time between the biomass char and the inner cylinder 21, thereby prolonging the heat exchange time between the biomass char and the inner cylinder 21. The impact mechanism 63 can impact large-sized biomass char to crush large-sized biomass and improve the heat exchange effect of biomass.
[0052] Continue to refer to Figures 6 to 9As shown, the lifting mechanism 61 includes an annular groove 611 formed on the inner wall of the inner cylinder 21. The inner wall of the annular groove 611 abuts against a lifting bar 612. The lifting bar 612 is arc-shaped and has multiple evenly distributed lifting protrusions 6121. The lifting bar 612 is made of an elastic material, and its elasticity allows it to adhere tightly to the annular groove 611. When the inner cylinder 21 rotates, the friction between the inner cylinder 21 and the lifting bar 612 drives the lifting bar 612 to rotate synchronously. The lifting protrusions 6121 on the lifting bar 612 can lift the biochar. When the lifting protrusions 6121 move upward with the inner cylinder 21, the biochar on the lifting protrusions 6121 detaches from the lifting protrusions 6121 under its own weight, thereby realizing the throwing of biochar and the turning of biochar.
[0053] In addition, when it is necessary to replace the lifting bar 612, force is applied to bend the lifting bar 612, which can be removed from the inner wall of the annular groove 611. Then, force is applied to bend the new lifting bar 612, and the new lifting bar 612 is kept in the annular groove 611 before being released, thus completing the installation of the new lifting bar 612 and improving the convenience of replacing the lifting bar 612.
[0054] Continue to refer to Figures 6 to 9 As shown, the biomass barrier 62 includes a biomass barrier ring 621, on which a connecting strip 622 is welded. The connecting strip 622 is welded to the inner wall of the inner cylinder 21. The biomass barrier ring 621, the inner wall of the inner cylinder 21, and the space between each pair of adjacent connecting strips 622 form a channel 623. The channel 623 allows small-sized biomass char smaller than the channel 623 to pass through, while large-sized biomass char larger than the channel 623 will be blocked upstream of the biomass barrier ring 621.
[0055] Continue to refer to Figures 6 to 9 As shown, the impact mechanism 63 includes a guide rod 631 welded to the inner wall of the inner cylinder 21. A sliding seat 632 is slidably connected to the outer surface of the guide rod 631 with a single degree of freedom. In this embodiment, the guide rod 631 is a triangular prism. The sliding seat 632 has a triangular hole that matches the guide rod 631. An impact head 633 is fixedly connected to the top and bottom of the sliding seat 632. The impact head 633 is positioned upstream of the carbon-blocking ring 621. As the inner cylinder 21 rotates, it drives the guide rod 631 to rotate synchronously. When the guide rod 631 rotates, it drives the sliding seat 632 to rotate. Whenever the guide rod 631 tends to be vertical, the sliding seat 632 and the impact head 633 can slide down along the guide rod 631 under their own weight. The impact head 633 located at the bottom falls to the upstream position of the carbon blocking ring 621 and impacts the large-sized biomass char blocked at the upstream position of the carbon blocking ring 621, causing the large-sized biomass char to be impacted into small-sized biomass char, which then continues to move through the channel 623, improving the heat exchange effect between the biomass char and the inner wall of the inner cylinder 21.
[0056] Two limiting blocks 634 are also welded on the guide rod 631. The two limiting blocks 634 are located on both sides of the sliding seat 632. When the sliding seat 632 moves down, it can fall on the limiting blocks 634. When the sliding seat 632 contacts the limiting blocks 634, there is a gap between the impact head 633 and the lifting protrusion 6121. The limiting blocks 634 can limit the maximum distance of the sliding seat 632 moving down, preventing the impact head 633 from directly colliding with the lifting protrusion 6121 and being damaged.
[0057] In use, the rotating drive device 15 is started to provide power to drive the double-layer drum 20 to rotate. The two pipe joints 52 are respectively connected to the external water circulation system as the water inlet and outlet for water circulation. Biomass char is added to the hopper 321 on the feed chute 32. The biomass char can fall into the inner cylinder 21 through the extension 322, realizing the feeding of biomass char. The biomass char moves down along the inclined inner cylinder 21. During this process, the rotation of the inner cylinder 21 drives the lifting mechanism 61, the char blocking part 62 and the impact mechanism 63 to rotate synchronously. The lifting protrusion 6121 on the lifting bar 612 can lift the biomass char. When the lifting protrusion 6121 moves to the top with the inner cylinder 21, the biomass char on the lifting protrusion 6121 is separated from the lifting protrusion 6121 under its own weight, thereby realizing the throwing of biomass char and the turning of biomass char, so that all parts of biomass char can fully contact the inner wall of the inner cylinder 21 for heat exchange.
[0058] Meanwhile, small-sized biomass char, smaller than the size of channel 623, can pass through channel 623, while large-sized biomass char, larger than the size of channel 623, will be blocked upstream of the char-blocking ring 621, extending the residence time of large-sized biomass char in the inner cylinder 21 and increasing the heat exchange time, so as to fully exchange heat between the large-sized biomass char and the inner cylinder 21.
[0059] Meanwhile, when the guide rod 631 rotates, it will drive the sliding seat 632 to rotate. Whenever the guide rod 631 tends to be vertical, the sliding seat 632 and the impact head 633 can slide down along the guide rod 631 under their own weight. The impact head 633 located at the bottom falls to the upstream position of the carbon blocking ring 621 and impacts the large-sized biomass char blocked at the upstream position of the carbon blocking ring 621, causing the large-sized biomass char to be impacted into small-sized biomass char, thereby improving the heat exchange effect between the biomass char and the inner wall of the inner cylinder 21.
[0060] Ultimately, the heat from the inner cylinder 21 is transferred to the water flowing through the water passage 23 to achieve a cooling effect on the biochar and improve the cooling efficiency.
