Description

Technical Field

[0001] The present invention relates to the technical field of agricultural recycling, and in particular to agricultural solid waste carbonization treatment equipment and a treatment method thereof. Background Art

[0002] Agricultural solid waste carbonization treatment equipment mainly uses the principle of pyrolysis in a high-temperature, oxygen-free environment to convert agricultural waste such as rice husks, straw and other fiber-containing crops into carbonaceous materials. This process is usually carried out under oxygen-free conditions. The high temperature causes the waste to be heated to undergo thermal decomposition reaction, and the organic matter is decomposed into substances with simple molecular structures, eventually forming carbonaceous materials. The carbonaceous materials are then crushed and compacted to form carbon blocks for easy transportation and storage.

[0003] However, in the process of carbonizing agricultural waste through a carbonization furnace, a large amount of carbon ash often remains on the inner wall of the carbonization furnace. At the same time, the thermal conductivity of carbon ash is poor, which makes it easy for subsequent agricultural solid waste to be unable to be completely carbonized during carbonization. At the same time, because agricultural solid waste contains fiber, it cannot be completely crushed subsequently. If it is compacted into carbon blocks, it is easy to cause the carbon blocks to loosen and break. At the same time, the combustible gas attached to the carbon ash in the carbonization furnace cannot be well collected, which can easily lead to dust explosions. Summary of the Invention

[0017] In addition, the present invention adopts the following technical solution, a treatment method of agricultural solid waste carbonization treatment equipment, comprising the following steps:

[0018] S1. First, the agricultural solid waste is transported to the carbonization furnace through the cage for carbonization. Then, the shaft is driven by the bracket motor to rotate, so that the inclined flap turns the agricultural solid waste and transmits it to the discharge shell. At the same time, the carbonized agricultural solid waste is crushed by the grinding wheel.

[0019] S2.

During the rotation of the coupling 1, it drives the spring to rotate and drives the gear ring to rotate through the spring. The rotation of the gear ring drives the pawl to rotate, and the pawl drives the shaft block to slide up and down, so that the filter plate bumps and improves the filtering effect of the carbonized fragments. If there is too much waste that cannot be filtered out by the filter plate and is not completely carbonized at the upper end of the filter plate, the filter plate will be crushed. The weight will increase, causing the gear ring to be resisted by the pawl and unable to rotate, so that the spring continues to rotate and compress, causing coupling 1 and coupling 2 to disengage, causing the spring to release its elastic restoring force to drive the scraper to scrape the inner wall of the carbonization furnace in the opposite direction, cleaning the internal carbon ash, and then scraping the carbon ash on the upper end of the filter plate and the agricultural waste that has not been completely carbonized through the sewage plate and transfer them to the inside of the waste box. At the same time, the air inlet pipe is blocked, so that the suction pump will extract the carbon ash dust and combustible gas together through the block to prevent dust explosion and secondary utilization of combustible gas with carbon ash.

DETAILED DESCRIPTION

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0036] See also Figures 1-9 The present invention provides a technical solution: an agricultural solid waste carbonization treatment device, comprising a carbonization furnace 2, the outer wall of the carbonization furnace 2 is provided with a combustion furnace 1, one end of the carbonization furnace 2 is welded with a twisting cage 42, a discharge shell 3 is fixedly installed on the end of the carbonization furnace 2 away from the twisting cage 42, and a positioning sleeve 5 is fixedly installed on the end of the discharge shell 3 away from the carbonization furnace 2, a shaft rod 4 is movably connected in the cavity of the positioning sleeve 5, and the shaft rod 4 passes through the carbonization furnace 2 and the discharge shell 3, and a conveying and cleaning structure is provided on the outer wall of the shaft rod 4, which can convey the agricultural waste in the cavity of the carbonization furnace 2 and clean the inner wall of the carbonization furnace 2;

[0037] The outer wall of the positioning sleeve 5 is rotatably connected to a gear ring 6, and a spring 7 is fixedly installed on the end of the gear ring 6 away from the discharge shell 3. A coupling 8 is fixedly installed on one end of the spring 7, and the coupling 8 is fixedly connected to the shaft 4. The side of the coupling 8 away from the spring 7 is engaged with a coupling 2 9. A bracket motor 10 is welded to the end of the discharge shell 3 away from the carbonizing furnace 2, and the output end of the bracket motor 10 is fixedly connected to the coupling 2 9;

[0038] The inner wall of the discharge shell 3 is slidably connected to the filter plate 20, and the inner wall of the discharge shell 3 is provided with a crushing structure, which is located on the upper side of the filter plate 20;

[0039] One end of the discharge shell 3 is rotatably connected to a pawl 11, and the pawl 11 is meshed with the gear ring 6. A vibration structure is provided on the side of the pawl 11 away from the gear ring 6, and the vibration structure can drive the filter plate 20 to vibrate;

[0040] An air intake pipe 31 is fixedly installed on the side surface of the discharge shell 3, and an exhaust structure is provided at the output end of the air intake pipe 31, which can discharge the carbon ash gas. The crushed agricultural solid waste is discharged into the interior of the carbonization furnace 2 through the cage 42. The lower notch of the discharge shell 3 can be connected to a screw conveyor to discharge the carbonized agricultural waste after it is crushed. The air intake pipe 31 is used to suck the combustible gas generated after the carbonization furnace 2 carbonizes the agricultural waste into the interior of the gas bin 29, and then the air pump 41 sucks it away for secondary utilization.

[0041] Specifically, refer to Figure 4 When the gear ring 6 rotates, the pawl 11 is pushed down and the gear ring 6 is engaged with the pawl 11 by the elastic recovery force of the torsion spring on the pawl 11 rotating shaft.

[0042] Among them, the conveying cleaning structure includes a number of rings 36, which are equidistantly arranged on the outer wall of the shaft 4, and a number of support rods 37 are installed in a circle on the outer wall of each ring 36. One end of each support rod 37 is fixed with an inclined flap 38, and a scraper 44 is provided on one side of the inclined flap 38. The inclined flap 38 and the scraper 44 are in contact with the inner wall of the carbonization furnace 2. An arc groove 39 is opened inside the ring 36, and the inner wall of the arc groove 39 is slidably connected with an arc block 40, and the arc block 40 is fixed to the shaft 4.

[0043] Among them, the crushing structure includes two grinding wheels 21, both of which are rotatably connected to the inner wall of the discharge shell 3, and there is a gap between the two grinding wheels 21. Two motors 22 are fixedly installed on the outer wall of the discharge shell 3, and the output end of the motor 22 is fixedly connected to the grinding wheel 21 at the corresponding position.

[0044] Specifically, refer to Figure 7The grinding wheel 21 on the left rotates clockwise, and the grinding wheel 21 on the right rotates counterclockwise, so that the agricultural waste inside the carbonization furnace 2 can be crushed into carbonized fragments after carbonization, so as to be compacted into carbon blocks. At the same time, there is a gap between the two grinding wheels 21 to prevent it from being ground into powder, which makes it easy to loosen after compaction and difficult to form a stable block.

[0045] Among them, the vibration structure includes a sliding shaft 43, which is slidingly connected to the pawl 11, and the lower end of the sliding shaft 43 is rotatably connected to the connecting rod 12. The lower end of the connecting rod 12 is fixedly installed with a rotating shaft block 14. The outer wall of the connecting rod 12 is slidingly connected with a positioning block 13, and the positioning block 13 is fixed to the outer wall of the discharge shell 3. A torsion spring is fixed between the rotating shaft of the pawl 11 and the discharge shell 3.

[0046] Among them, two symmetrically positioned crowbars 15 are rotatably connected to both sides of the rotating shaft block 14, and a sliding groove 16 is provided on the outer wall of the crowbar 15. A positioning column 17 is movably connected in the cavity of the sliding groove 16, and the positioning column 17 is fixed to the outer wall of the discharge shell 3. A rotating shaft 18 is slidably connected to the outer wall of the crowbar 15, and a slider 19 is rotatably connected to the side of the rotating shaft 18 close to the filter plate 20. The slider 19 is fixed to the outer wall of the filter plate 20, and the slider 19 is slidably connected to the outer wall of the discharge shell 3.

[0047] Specifically, refer to Figure 4 When the pawl 11 is pushed by the gear ring 6, the pawl 11 will continue to rotate counterclockwise and then reset. During this process, the connecting rod 12 will be pushed to slide downward in the cavity of the positioning block 13 and then lifted up to reset. At the same time, during the sliding process of the connecting rod 12, the sliding shaft 43 will slide on one side of the pawl 11, and the connection with the connecting rod 12 will rotate slightly to adapt to the up and down sliding of the connecting rod 12. Figure 5In the process of connecting rod 12 driving shaft block 14 to slide downward, the crowbar 15 will lift one end of the rotating shaft 18 through the positioning column 17, thereby allowing the slider 19 to slide upward, and at the same time, the sliding groove 16 slides a distance on the outer wall of the positioning column 17, thereby adapting to the extension phenomenon generated by the crowbar 15 during the rotation process. In the process of rotating shaft 18 sliding upward, the crowbar 15 will also slide on the side surface of the rotating shaft 18. As the pawl 11 drives the connecting rod 12 to slide downward continuously, it will drive the slider 19 to slide upward continuously, and the slider 19 is fixedly connected to the filter plate 20, which will drive the filter plate 20 to continuously bump upward, so that the carbonized fragments on the upper end of the filter plate 20 can be quickly filtered down to avoid precipitation and accumulation. At the same time, when the carbon ash in the cavity of the carbonizing furnace 2 is too thick, it will affect the carbonization effect of the carbonizing furnace 2 on agricultural waste. Since the agricultural waste contains fiber components, if it is not completely carbonized, the crushing device will not be able to crush it completely. At this time, it will fall to the upper end of the filter plate 20 and cannot be filtered. At this time, as the accumulation on the upper end of the filter plate 20, the counterweight of the filter plate 20 will increase, so that the slider 19 cannot slide upward, and the connecting rod 12 cannot slide downward. At this time, the gear ring 6 will be fixed in place and cannot rotate. As the coupling 1 8 rotates, the spring 7 will be contracted and rotated, and the coupling 1 8 will gradually disengage from the coupling 2 9. When the counterweight of the filter plate 20 can make the coupling 1 8 rotate one circle and the gear ring 6 cannot rotate, the coupling 1 8 and the coupling 2 9 will disengage, so that the spring 7 releases the elastic restoring force, driving the coupling 1 8 and the shaft 4 to rotate one circle in the opposite direction, until the upper end of the coupling 1 8 contacts the coupling 2 9 again. Figure 8 During the reverse rotation of the shaft 4, the arc block 40 is driven to rotate counterclockwise, causing the arc block 40 to come into contact with the inner wall of the arc groove 39, thereby driving the collar 36 to rotate counterclockwise. During the counterclockwise rotation of the collar 36, the scraper 44 scrapes the inner wall of the carbonizing furnace 2 for half a circle, and then the coupling 1 8 contacts the coupling 2 9 again and rotates, thereby scraping the carbon ash on the inner wall of the carbonizing furnace 2 back and forth and transmitting it toward the discharge shell 3.

[0048] Among them, two symmetrically positioned sewage grooves 23 are opened on both sides of the discharge shell 3, and the inner wall of the sewage groove 23 is slidably connected with a sewage plate 24, and the sewage plate 24 can contact the upper surface of the filter plate 20. The end of the discharge shell 3 away from the positioning sleeve 5 is fixedly installed with a cylinder 26, and the output end of the cylinder 26 is fixedly installed with an L-shaped connecting rod 25, and the L-shaped connecting rod 25 is fixedly connected to the sewage plate 24.

[0049] Among them, the exhaust structure includes a waste box 27, and the waste box 27 is fixedly connected to the side of the discharge shell 3 away from the sewage discharge plate 24, and the waste box 27 is connected to the sewage discharge trough 23. The upper end of the waste box 27 is fixedly connected to the air bin 29, and the upper end of the air bin 29 is connected to the lower slot of the air inlet pipe 31. The upper end of the waste box 27 is installed with an air suction pipe 30, and the upper slot of the air suction pipe 30 is provided with an air suction pump 41.

[0050] Among them, a baffle 28 is slidably connected to the cavity of the waste box 27, and the baffle 28 can conflict with the slot of the drain trough 23. The upper end of the baffle 28 is fixedly installed with a connecting rod 2 34 that is slidably connected to the waste box 27. The upper end of the connecting rod 2 34 is fixedly connected to a sealing plate 35, and the sealing plate 35 can conflict with the lower slot of the air intake pipe 31. A stopper 32 is fixed on the outer wall of the connecting rod 2 34, and a return spring 33 is fixed between the stopper 32 and the air chamber 29, wherein the stopper 32 covers the slot of the connecting rod 2 34 for sliding to seal the slot.

[0051] Specifically, when the carbon ash inside the carbonization furnace 2 is scraped to the inside of the discharge shell 3, the carbon ash will fall to the upper surface of the filter plate 20. At this time, a layer of agricultural waste that has not been completely carbonized has been attached to the upper surface of the filter plate 20. The cylinder 26 will drive the sewage plate 24 to scrape the upper surface of the filter plate 20 through the holes of the sewage trough 23. At the same time, the filter plate 20 is at the lowest point due to the influence of gravity. As the sewage plate 24 scrapes, the agricultural waste that has not been completely carbonized on the upper surface of the filter plate 20 and the carbon ash will be pushed to the waste box 2. 7, during the pushing process, the sewage plate 24 carrying the carbon ash will conflict with and push the baffle 28, and during the sliding process of the baffle 28, the connecting rod 23 and the block 32 will also slide, and the return spring 33 will be compressed. During the sliding process of the connecting rod 23, the blocking plate 35 will move synchronously and block the return spring 33. At this time, the suction pump 41 will extract the combustible gas through the holes of the sewage trough 23, preventing the carbon ash from causing dust explosion. At the same time, the gas with carbon ash is reused, saving energy.

[0052] Working principle: The agricultural waste that needs to be carbonized is transported to the interior of the carbonizing furnace 2 through the cage 42, and then the coupling 2 9 is driven to rotate by the bracket motor 10, so that the coupling 2 9 drives the coupling 1 8 to rotate, and then drives the shaft 4 to rotate, so that the inclined flap 38 can stir the agricultural waste inside the carbonizing furnace 2 and transport it in the direction of the discharge shell 3. When it is transported to the discharge shell 3 into the cavity, the carbonized waste is crushed by the grinding wheel 21. In the process of the rotation of the coupling 1 8, the spring 7 is driven to rotate and compress it. In the process of the rotation and compression of the spring 7, the gear ring 6 is driven to rotate, so that the gear ring 6 rotates and pushes the ratchet 11 to rotate. The ratchet 11 then drives the shaft block 14 to slide up and down, so that the filter plate 20 bumps to improve the filtering effect of the carbonized crushed material. If there are too many unfiltered particles on the upper end of the filter plate 20, the filter plate 20 will be shaken to improve the filtering effect of the carbonized crushed particles. When the agricultural waste is completely carbonized, it will not be able to be filtered smoothly by the filter plate 20. At this time, the counterweight on the upper end of the filter plate 20 will be increased, so that the gear ring 6 is resisted by the pawl 11 and cannot rotate, so that the spring 7 continues to rotate and compress, so that the coupling 1 8 and the coupling 2 9 are disengaged, causing the spring 7 to release the elastic recovery force to drive the scraper 44 to scrape the inner wall of the carbonization furnace 2 in the opposite direction to clean the internal carbon ash. Then, the carbon ash on the upper end of the filter plate 20 and the agricultural waste that has not been completely carbonized are scraped through the sewage plate 24 and transmitted to the inside of the waste box 27. At the same time, the air inlet pipe 31 is blocked, so that the suction pump 41 will extract the carbon ash dust and combustible gas together through the block 32 to prevent dust explosions and the secondary utilization of combustible gas with carbon ash.

[0053] A method for treating agricultural solid waste carbonization equipment comprises the following steps:

[0054] S1. First, the agricultural solid waste is transported to the carbonization furnace 2 for carbonization through the cage 42. Then, the shaft 4 is driven to rotate by the bracket motor 10, so that the inclined flap 38 flips the agricultural solid waste and transmits it to the discharge shell 3. At the same time, the carbonized agricultural solid waste is crushed by the grinding wheel 21.

[0055] S2. The bracket motor 10 drives the gear ring 6 to rotate, so that the gear ring 6 drives the pawl 11 to rotate and reset continuously, thereby causing the pawl 11 to drive the vibration structure to move, thereby causing the filter plate 20 to shake up and down to filter the crushed carbonized waste.

[0056] S3, the suction pump 41 extracts the combustible gas inside the carbonization furnace 2 through the air inlet pipe 31. At the same time, when there is too much uncarbonized agricultural waste on the filter plate 20, it will be pushed into the waste box 27 by the sewage plate 24. At the same time, the suction pump 41 will extract the carbon ash and combustible gas together through the sewage trough 23.
