Description

Technical Field

[0001] The invention relates to the technical field of biochar production equipment, and in particular to a novel drum cooling and charcoal discharging device. Background Art

[0002] The carbonization furnace is a device for carbonizing combustible raw materials (wood, straw, sawdust, etc.). The carbonization furnace adopts the principle of dry distillation carbonization. The raw materials are heated and decomposed under the condition of air isolation to achieve carbonization. After the biomass carbonization is completed, it is in a high temperature state and the biochar needs to be cooled. Conventional biochar cooling methods generally include natural cooling and water cooling. The natural cooling method is to directly expose the biochar to the air for cooling, which takes a long time and has low efficiency; the water cooling method is to directly sprinkle water on the biochar to cool it down, but this method makes the biochar have a high water content, which seriously reduces the quality of the biochar.

[0003] In order to avoid the shortcomings of the above-mentioned biomass charcoal cooling method, there is also a separate heat exchange method in the prior art: Figure 1 As shown, the biochar is slid through the double-layer drum 20, and the circulating water pump 70 is controlled to pump the cool water in the circulating water pool 80 to between the outer cylinder and the inner cylinder of the double-layer drum 20, so that the biochar exchanges heat with the cooling water through the inner cylinder of the double-layer drum 20, thereby achieving the purpose of lowering the temperature of the biochar. The generated hot water is then passed through a pipeline into a cooling tower 90 for heat release and cooling. The water after heat release and cooling in the cooling tower 90 flows into the circulating water pool 80 again, thereby realizing water circulation.

[0004] However, this approach still has shortcomings: First, when the biochar slides in 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 contact the inner wall of the drum, which makes it easy for the biochar to exchange heat unevenly and reduces the cooling effect of the biochar; Second, biochars are of different sizes. Small-sized biochars are easy to cool down, while large-sized biochars are prone to inadequate heat exchange, resulting in unqualified cooling of large-sized biochars, which also reduces the cooling effect of the biochars. Summary of the invention

[0005] The present invention provides a novel drum cooling and charcoal discharging device, aiming to solve the problems in the related art that when the biochar is cooled in the drum, all parts of the biochar cannot contact the inner wall of the drum for heat exchange, and large-sized biochar is prone to inadequate heat exchange.

At the same time, the impact mechanism can impact the large-sized biochar, so that the large-sized biochar impacts into small-sized biochar, so that the biochar heat exchange is in place, so that the biochar is cooled to a qualified level, and the heat exchange effect between the biochar and the inner wall of the inner cylinder is improved.

[0008] Preferably, the lifting mechanism comprises a lifting bar arranged on the inner wall of the inner cylinder, the lifting bar has a plurality of lifting protrusions, and when the lifting bar rotates with the inner cylinder, the lifting protrusions can drive the biomass charcoal to be first lifted and then released.

[0015] As the inner cylinder rotates, the inner cylinder can drive the guide rod to rotate synchronously, and the guide rod will drive the sliding seat to rotate when it rotates.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] like Figures 2 to 9 As shown, the novel drum cooling and charcoal discharging device of the present invention includes a support 10 for supporting the novel drum cooling and charcoal discharging device of the present invention, a double-layer drum 20 which is rotatably connected to the support 10 and arranged obliquely, a feeding structure 30 extends to the highest end of the double-layer drum 20, a discharging cover 40 is matched with the lowest end of the double-layer drum 20, a water supply mechanism 50 is connected to the support 10, a plurality of processing mechanisms 60 are arranged in the double-layer drum 20, and the biochar in the double-layer drum 20 can be processed so that the biochar in the double-layer drum 20 can fully exchange heat with the double-layer drum 20, the biochar can be added into the double-layer drum 20 through the feeding structure 30, and the heat of the biochar is transferred to the double-layer drum 20, and the water supply mechanism 50 can flow water through the double-layer drum 20 to cool the double-layer drum 20.

[0035] refer to Figures 2 to 4As shown, the support 10 includes a frame 11, and a moving wheel 12 is installed at the bottom of the frame 11. When the support 10 is pushed or pulled, the moving wheel 12 can roll on the ground to facilitate moving 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, and the support rollers 14 are respectively supported on both sides of the double-layered drum 20 to stably support the double-layered drum 20. When the double-layered drum 20 rotates, the support rollers 14 can roll with the rotation of the double-layered drum 20 to reduce the friction between the support 10 and the double-layered drum 20. A rotation drive device 15 is installed on the frame 11, and the rotation drive device 15 provides power to drive the double-layered drum 20 to rotate.

[0036] Exemplarily, the rotation driving device 15 includes a reduction motor 151 fixedly mounted on the frame 11, and an abutment roller 152 is fixedly mounted on the output end of the reduction motor 151, and the abutment roller 152 abuts against the outer surface of the double-layered drum 20. Driving the reduction motor 151 can drive the abutment roller 152 to rotate, and the rotation of the abutment roller 152 can drive the double-layered drum 20 to rotate through the friction force between the abutment roller 152 and the double-layered drum 20, thereby realizing the rotation function of the double-layered drum 20.

[0037] refer to Figure 2 , Figure 3 and Figure 5 As shown, the double-layer drum 20 includes an inner drum 21, which is tilted and has an angle of 15-75 degrees with the horizontal plane. An outer drum 22 is welded to the outer surface of the inner drum 21, and a water passage cavity 23 is formed between the inner drum 21 and the outer drum 22. The water passage cavity 23 is connected to a water conveying mechanism 50, and the water conveying mechanism 50 can pass water into the water passage cavity 23. When the water passes through the water passage cavity 23, the double-layer drum 20 can be heat-exchanged and cooled. At least one limiting ring 24 is welded to the outer surface of the outer drum 22, and a limiting groove 25 is integrally formed on the limiting ring 24. At least one supporting roller 14 is limited to roll in the limiting groove 25. The limiting groove 25 limits the supporting roller 14, so that the double-layer drum 20 can be prevented from moving along the axial direction of the double-layer drum 20, thereby ensuring the stable cooperation between the double-layer drum 20 and the support 10 and preventing the double-layer drum 20 from being misaligned.

[0038] refer to Figure 2 , Figure 3 and Figure 6As shown, the feed structure 30 includes a sealing plate 31 welded on the frame 11, and the sealing plate 31 is rotatably connected to the inner wall of the inner tube 21 through a bearing. A feed chute 32 is welded on the sealing plate 31. It should be noted that the feed chute 32 has a hopper portion 321 and an extension portion 322 connected to the hopper portion 321. The hopper portion 321 is funnel-shaped with a larger upper portion and a smaller lower portion. The extension portion 322 is welded on the sealing plate 31, and the extension portion 322 extends to the interior of the inner tube 21. When biochar is added to the hopper portion 321 on the feed chute 32, the biochar can fall into the inner tube 21 through the extension portion 322, thereby realizing the feeding of the biochar.

[0039] refer to Figure 2 , Figure 3 and Figure 7 As shown, the discharge cover 40 is welded on the support 10, and the discharge cover 40 is rotatably connected to the outer surface of the lowest end of the inner cylinder 21 through a bearing. A discharge port 41 is opened below the discharge cover 40. After passing through the inner cylinder 21, the biochar is discharged from the lowest end of the inner cylinder 21 and falls into the discharge cover 40, and is finally discharged in a directed manner from the discharge port 41 below the discharge cover 40.

[0040] refer to Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, the water delivery mechanism 50 includes two water-passing components, and the two water-passing components are respectively located at the two ends of the double-layer drum 20. In each water-passing component, the water-passing component includes a connecting frame 51 welded on the frame body 11, and a pipe joint 52 is provided on the connecting frame 51. The central axis of the pipe joint 52 is colinear with the central axis of the double-layer drum 20, and the inner wall of the pipe joint 52 is rotatably connected with a water-passing pipe 53 through a sealed bearing. The end of the water-passing pipe 53 away from the pipe joint 52 is welded to the inner cylinder 21, and the water-passing pipe 53 passes through the inner cylinder 21 and communicates with the water-passing cavity 23. When the inner cylinder 21 rotates, the water-passing pipe 53 can rotate synchronously with the inner cylinder 21, and the water-passing pipe 53 also rotates with the pipe joint 52 through the sealed bearing. The two pipe joints 52 are respectively connected to the external water circulation system as the water inlet and the water outlet, and the two water-passing pipes 53 are respectively rotatably connected to the sealing plate 31 and the discharge cover 40 through bearings.

[0041] Exemplarily, the external water circulation system includes a circulating water pump, a cooling tower and a circulating water pool. The water outlet of the cooling tower is connected to the circulating water pool, and the circulating water pool is connected to the water inlet of the circulating water pump through a pipeline. The water outlet of the circulating water pump is connected to a pipe joint 52 through a pipeline, and another pipe joint 52 is connected to the cooling tower through a pipeline. In this way, the circulating water pump can pump the cold water in the circulating water pool into a pipe joint 52, and then inject it into the water passage cavity 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, and the hot water flows to the other pipe joint 52 through another water passage pipe 53. Subsequently, the hot water is passed into the cooling tower through a pipeline for heat release and cooling. The water after heat release and cooling in the cooling tower flows into the circulating water pool again, thereby realizing the recycling of water and achieving the purpose of saving water resources.

[0042] refer to Figure 3 , Figures 6 to 9 As shown, each processing mechanism 60 includes a lifting mechanism 61, a charcoal blocking member 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 biochar in the inner cylinder 21 to lift the biochar and turn the biochar in the inner cylinder 21, so that all parts of the biochar can contact the inner wall of the inner cylinder 21 for heat exchange. The charcoal blocking member 62 can block large-sized biochar, so that the biochar stays in the inner cylinder 21 more, thereby increasing the contact time between the biochar and the inner cylinder 21, thereby extending the heat exchange time between the biochar and the inner cylinder 21. The impact mechanism 63 can impact large-sized biochar to crush the large-sized biomass and improve the heat exchange effect of the biomass.

[0043] Continue to refer Figures 6 to 9 As shown, the lifting mechanism 61 includes an annular groove 611 formed on the inner wall of the inner cylinder 21, and a lifting bar 612 is abutted against the inner wall of the annular groove 611. The lifting bar 612 is arc-shaped and has a plurality of evenly distributed lifting protrusions 6121 on the lifting bar 612. The lifting bar 612 is made of elastic material, and its elastic force can make the lifting bar 612 close to the annular groove 611. When the inner cylinder 21 rotates, the friction between the inner cylinder 21 and the lifting bar 612 can drive the lifting bar 612 to rotate synchronously, and the lifting protrusion 6121 on the lifting bar 612 can lift the biochar. When the lifting protrusion 6121 moves to the upper side with the inner cylinder 21, the biochar on the lifting protrusion 6121 separates from the lifting protrusion 6121 under its own weight, thereby realizing the throwing of the biochar, and then realizing the flipping of the biochar.

[0044] In addition, when the lifting strip 612 needs to be replaced, force is applied to bend the lifting strip 612 to remove it from the inner wall of the annular groove 611, and then force is applied to bend a new lifting strip 612. The bent new lifting strip 612 is kept placed in the annular groove 611 and then released, and the installation of the new lifting strip 612 is completed, thereby improving the convenience of replacing the lifting strip 612.

[0045] Continue to refer Figures 6 to 9 As shown, the charcoal retaining member 62 includes a charcoal retaining ring 621, on which a connecting strip 622 is welded, and the connecting strip 622 is welded to the inner wall of the inner tube 21. The charcoal retaining ring 621, the inner wall of the inner tube 21 and each adjacent two connecting strips 622 form a channel 623, and the channel 623 can allow small-sized biochar smaller than the size of the channel 623 to pass through, while large-sized biochar larger than the size of the channel 623 will be retained at the upstream position of the charcoal retaining ring 621.

[0046] Continue to refer Figures 6 to 9 As shown, the impact mechanism 63 includes a guide rod 631 welded to the inner wall of the inner tube 21, and the outer surface of the guide rod 631 is slidably connected with a sliding seat 632 in a single degree of freedom. In this embodiment, the guide rod 631 is a triangular prism, and the sliding seat 632 is provided with a triangular hole that matches the guide rod 631. The top and bottom of the sliding seat 632 are fixedly connected with an impact head 633, and the impact head 633 is directly opposite to the upstream position of the carbon retaining ring 621. As the inner cylinder 21 rotates, the inner cylinder 21 can drive the guide rod 631 to rotate synchronously. 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 below falls to the upstream position of the charcoal retaining ring 621, and impacts the large-sized biochar blocked at the upstream position of the charcoal retaining ring 621, so that the large-sized biochar is impacted into small-sized biochar, and then continues to move through the channel 623, thereby improving the heat exchange effect between the biochar and the inner wall of the inner cylinder 21.

[0047] Two limiting blocks 634 are welded on the guide rod 631, and the two limiting blocks 634 are located on both sides of the sliding seat 632. The sliding seat 632 can move downward and fall on the limiting blocks 634. When the sliding seat 632 contacts the limiting blocks 634, a gap is left between the impact head 633 and the material lifting protrusion 6121. The limiting blocks 634 can limit the maximum distance of the sliding seat 632 moving downward, thereby preventing the impact head 633 from directly colliding with the material lifting protrusion 6121 and being damaged.

[0048] When in use, the rotation drive device 15 is started to provide power to drive the double-layer drum 20 to rotate, and the two pipe joints 52 are respectively connected to the external water circulation system as the water inlet and the water outlet for water flow, and the biochar is added to the hopper part 321 on the feed chute 32, and the biochar can fall into the inner cylinder 21 through the extension part 322 to realize the addition of biochar, and the biochar moves downward along the inclined inner cylinder 21. During this period, the rotation of the inner cylinder 21 drives the lifting mechanism 61, the charcoal blocking member 62 and the impact mechanism 63 to rotate synchronously, and the lifting protrusion 6121 on the lifting bar 612 can lift the biochar. When the lifting protrusion 6121 moves to the upper side with the inner cylinder 21, the biochar on the lifting protrusion 6121 separates from the lifting protrusion 6121 under its own weight, thereby realizing the throwing of the biochar, and then realizing the flipping of the biochar, so that all parts of the biochar are fully in contact with the inner wall of the inner cylinder 21 for heat exchange.

[0049] At the same time, small-sized biochar smaller than the size of channel 623 can pass through channel 623, while large-sized biochar larger than the size of channel 623 will be blocked at the upstream position of the biochar blocking ring 621, extending the residence time of the large-sized biochar in the inner tube 21 and increasing the heat exchange time, so as to fully allow the large-sized biochar to fully exchange heat with the inner tube 21.

[0050] At the same time, 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, and the impact head 633 located below falls to the upstream position of the charcoal retaining ring 621, and impacts the large-sized biochar blocked at the upstream position of the charcoal retaining ring 621, so that the large-sized biochar is impacted into small-sized biochar, thereby improving the heat exchange effect between the biochar and the inner wall of the inner tube 21.

[0051] Finally, the heat of the inner cylinder 21 is transferred to the water flowing through the water passage cavity 23 to achieve the cooling effect of the biochar and improve the cooling effect.
