An apparatus and method for preparing cassava carbon soil

Abstract

This invention discloses a cassava carbon preparation apparatus and method in the field of carbon preparation technology. The apparatus includes a crushing chamber with a primary crushing wheel inside. A third conveyor belt is located at the bottom of the primary crushing wheel. A smoldering furnace is located behind the crushing chamber, and a first feed inlet is provided above the smoldering furnace for docking with the rear end of the third conveyor belt. This invention adds a pre-crushing and conveying mechanism during cassava carbon preparation. Before the dried cassava by-products are crushed in the crushing chamber, the pre-crushing and conveying mechanism pre-crushes the by-products, cutting off the branches. This ensures that the cassava by-products remain long and thin when entering the crushing chamber, reducing branching. Simultaneously, the cut branches are fed into the crushing chamber along with the roots and stems, effectively reducing root and stem breakage during crushing and resulting in better crushing of the cassava by-products.

Description

Technical Field

[0001] This invention relates to the field of carbon soil preparation technology, specifically to an apparatus and method for preparing cassava carbon soil. Background Technology

[0002] Cassava is a root crop, primarily harvested for its underground tubers. The main byproducts obtained after harvesting are stems and old seed tubers, which have a relatively large biomass. These byproducts, including plant stems, leaves, and roots, are rich in organic matter and essential nutrients such as nitrogen, phosphorus, and potassium. Mixing these byproducts with soil to prepare cassava carbon soil can partially replace chemical fertilizers, reducing fertilizer use, significantly improving soil physicochemical properties and microbial richness, and enhancing soil fertility. Furthermore, the high-temperature firing process of the carbon soil provides strong control over soil-borne diseases and pathogens. In addition, the excellent aeration and water retention properties of carbon soil promote root growth and development, thus contributing to the long-term sustainable development of the agricultural ecosystem. Therefore, the preparation of cassava carbon soil using cassava byproducts has promising application prospects.

[0003] In the preparation of cassava charcoal, air-dried cassava by-products are pulverized into root fragments less than 15 cm in length using a pulverizer. These fragments are then added to a stoker and mixed with an appropriate amount of soil. After stokeration, cassava charcoal can be produced. However, cassava roots and stems are relatively long and have many branches. Furthermore, the dried roots and stems are quite brittle. During pulverization, the branches on the cassava by-products are prone to breakage. These broken branches will bounce out of the pulverizer irregularly, posing a high risk. Moreover, this will cause the branches of the cassava by-products to scatter outside the pulverizer during pulverization, affecting the pulverization effect.

[0004] Based on this, the present invention designs a cassava charcoal preparation device and method to solve the problem that the cassava by-product branches are easily ejected outside the crusher during crushing, affecting the crushing effect. Summary of the Invention

[0013] A method for preparing cassava charcoal, using a cassava charcoal preparation apparatus, includes the following steps:

[0014] Step 1: After the waste cassava by-products are air-dried, they are put into a fixed frame. Inside the fixed frame, the cassava by-products are initially crushed by a pre-crushing and conveying mechanism to obtain crushed material 1.

[0015] Step 2: The obtained fragment 1 is fed into the crushing chamber and crushed again by the primary crushing wheel to obtain fragment 2; then it is transported to the interior of the stoking furnace by the third conveyor belt;

[0016] Step 3: Add an appropriate amount of soil to the inside of the curing oven along with the crushed material from Step 2, and then curdle it inside the curing oven.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: By adding a pre-crushing and conveying mechanism during the preparation of cassava charcoal, the cassava by-products are pre-crushed by the pre-crushing and conveying mechanism before being crushed in the crushing chamber. This pre-crushing and conveying mechanism cuts off the branches on the cassava by-products, so that the cassava by-products can maintain a long strip shape and reduce branching when entering the crushing chamber. At the same time, the cut branches are sent into the crushing chamber along with the roots and stems for crushing, which effectively reduces the breakage of the roots and stems during the crushing process, resulting in a better crushing effect of the cassava by-products.

Detailed Implementation

[0028] The following description of the embodiments uses the accompanying drawings. Identical parts in the drawings are labeled with the same symbols, and detailed descriptions are omitted where appropriate; different parts are described separately. Furthermore, the drawings are schematic or conceptual, and the relationship between the thickness and width of each part, the ratio of sizes between parts, etc., may not be the same as in reality. Also, even when representing identical parts, there may be cases where the dimensions and ratios differ depending on the drawing.

[0029] Please see Figures 1-8The present invention provides a technical solution: a cassava charcoal preparation device, including a crushing chamber 2, a primary crushing wheel 10 is provided inside the crushing chamber 2, a third conveyor belt 12 is provided at the bottom of the primary crushing wheel 10, a stoking furnace 3 is provided at the rear side of the crushing chamber 2, a first feed port 4 is provided above the stoking furnace 3 for docking with the rear end of the third conveyor belt 12, a fixed frame 1 is fixedly connected to the front end of the crushing chamber 2, a first conveyor belt 8 is fixedly connected inside the fixed frame 1, and a pre-crushing and transporting mechanism is provided inside the fixed frame 1. The pre-crushing and transporting mechanism is used to pre-crush the cassava by-products to reduce the breakage of the cassava by-products during crushing.

[0030] When the above scheme is put into practical use, the waste cassava stalks, old seed stems and other by-products are air-dried and put into the fixed frame 1. Inside the fixed frame 1, the cassava by-products are initially crushed by the pre-crushing and conveying mechanism. The crushed product then enters the crushing chamber 2, is crushed again by the first-stage crushing wheel 10, and is then transported to the coking furnace 3 by the third conveyor belt 12. An appropriate amount of soil is added to the coking furnace 3 to match the cassava by-products entering the coking furnace 3. The coking process is carried out inside the coking furnace 3. After the coking is completed, the cassava charcoal soil can be taken out from the discharge port at the bottom of the coking furnace 3. The advantage of this is that before the cassava by-products are crushed by the crushing and conveying mechanism, the cassava by-products are initially crushed by the pre-crushing and conveying mechanism, and the branches on the cassava by-products are cut off. This ensures that the cassava by-products can maintain a long strip shape and reduce branching when they enter the crushing chamber 2. At the same time, the cut branches are sent into the crushing chamber 2 along with the roots and stems to ensure that the breakage of the roots and stems is effectively reduced during the crushing process, resulting in a better crushing effect of the cassava by-products.

[0031] As a further embodiment of the present invention, the pre-crushing and conveying mechanism includes a transmission track 14, which is rotatably disposed inside the fixed frame 1. A plurality of rotating rollers 15 are disposed inside the transmission track 14, with both ends of each roller 15 rotatably connected to the inner wall of the fixed frame 1. A plurality of equidistantly distributed fixed plates 18 are fixedly connected to the transmission track 14. Sliding seats 17 are slidably sleeved on the outside of the fixed plates 18. A fixed spring for resetting the sliding seat 17 is fixedly connected to the sliding seat 17. A pressing block 16 is fixedly connected to the top of the sliding seat 17. A transmission wheel 19 is rotatably connected inside the fixed frame 1. The transmission wheel 19 and the rotating rollers 15 are jointly connected to a transmission belt 21. A lever 20 is fixedly connected to the side wall of the transmission wheel 19. A first toothed plate 31 and a second toothed plate 34 are slidably connected to the inner wall of the fixed frame 1. The first toothed plate 31 and the second toothed plate 34 mesh together with a transmission gear 33. A connecting shaft 32 is fixedly connected to the top of the transmission gear 33. The top of the connecting shaft 32 is fixedly connected to the inner wall of the fixed frame 1. A first rotating rod 30 is rotatably connected to the front end of the first toothed plate 31. A second rotating rod 36 is rotatably connected to the rear end of the second toothed plate 34. A pressure plate 13 is rotatably connected to the bottom of the first rotating rod 30 and the second rotating rod 36. A docking rod 35 for docking with the lever 20 is fixedly connected to the rear end of the second toothed plate 34.

[0032] When the above solution is put into practical use, when crushing cassava by-products, the air-dried cassava by-products are placed on the first conveyor belt 8. It should be noted that when placing the cassava by-products, the tail end of the root is placed on the first conveyor belt 8, that is, the end of the root with branches is facing forward. The purpose of this is that during transportation, the squeezing block 16 will contact and restrict the tail end first, and then separate the branches at the front end. After being transported through the first conveyor belt 8 to the fixed frame 1, the drive device drives the transmission track 14 to rotate, and the rotation speed of the transmission track 14 is consistent with the transmission speed of the first conveyor belt 8. When the cassava by-products slide to the bottom of the transmission track 14, the squeezing block 16 on the transmission track 14 will contact the cassava by-products as the transmission track 14 rotates, and the contact pressure gradually increases as the transmission track 14 rotates, causing the sliding seat 17 to retract onto the fixed plate 18 to compress the fixing spring. Since the rotation speed of the transmission track 14 and the first conveyor belt 8 is the same, the root is fixed by the squeezing block 16, which can restrict the position of the root and transport the root.

[0033] As the transmission track 14 rotates via the rotating roller 15, it drives the transmission wheel 19 to rotate via the transmission belt 21, causing the lever 20 to contact the docking rod 35. The rotation of the lever 20 pushes the docking rod 35 forward, causing it to slide along with the second toothed plate 34. The second toothed plate 34 drives the transmission gear 33 to rotate, and the transmission gear 33 simultaneously drives the first toothed plate 31 to slide. The first toothed plate 31 and the second toothed plate 34 slide in opposite directions. The first toothed plate 31 and the second toothed plate 34 respectively drive the first rotating rod 30 and the second rotating rod 36 to rotate, causing the bottom pressure plate 13 to slide downwards. When the lever 20 rotates to the position where it is no longer in contact with the docking rod 35, the connecting shaft 32 is sleeved... A first torsion spring is fixedly connected to the bottom of the transmission gear 33. As the transmission gear 33 rotates, the first torsion spring gradually increases the pressure. After being released from the pressure of the lever 20, the first torsion spring drives the transmission gear 33 to reverse, causing the first toothed plate 31 and the second toothed plate 34 to reset, thereby driving the pressure plate 13 to reset upward, thus forming an up-and-down cycle of the pressure plate 13 until the lever 20 rotates again to the position of contacting the docking rod 35. The purpose of this is to break the branches on the cassava by-product that have been fixed by the extrusion block 16 by pressing the vertically downwards of the pressure plate 13. Since the roots and stems are already in a dried state at this time, they can be broken by ordinary pressing, thus performing a preliminary crushing treatment on the cassava by-product.

[0034] As a further embodiment of the present invention, a second conveyor belt 9 is fixedly connected inside the bottom end of the fixed frame 1, and the side wall of the second conveyor belt 9 can fit against the side wall of the fixed frame 1. A secondary crushing wheel 11 corresponding to the position of the second conveyor belt 9 is rotatably connected inside the crushing chamber 2.

[0035] When the above scheme is put into actual use, the branches that are broken by the pressure plate 13 may also break off. The broken branches will fall above the second conveyor belt 9 and then be transported by the second conveyor belt 9 through the secondary crushing wheel 11 for crushing, ensuring that the roots and stems on the second conveyor belt 9 and the first conveyor belt 8 can be effectively crushed.

[0036] As a further embodiment of the present invention, a connecting disc 27 is fixedly connected to the transmission wheel 19, a convex shaft 26 is fixedly connected to the outer wall of one end of the connecting disc 27, a connecting frame 28 is slidably sleeved on the outside of the convex shaft 26, a connecting plate 22 is fixedly connected to the side wall of the connecting frame 28, a rack plate 23 is fixedly connected to the front end of the connecting plate 22, a telescopic rod 29 is slidably connected to the top end of the rack plate 23, the top end of the telescopic rod 29 is fixedly connected to the inner wall of the fixed frame 1, and a rotating wheel 25 is rotatably sleeved on the first conveyor belt 8. The outer wall of the rotating wheel 25 is provided with gear teeth for meshing with the rack plate 23, and a sawtooth 24 is fixed to the front end of the rotating wheel 25.

[0037] When the above scheme is put into actual use, when the transmission track 14 rotates to pre-crush the cassava by-products, the rotation of the transmission wheel 19 will drive the connecting disc 27 to rotate. The connecting disc 27 drives the connecting frame 28 to slide up and down through the convex shaft 26. The connecting frame 28 drives the rack plate 23 to slide back and forth outside the telescopic rod 29 through the connecting plate 22. When the rack plate 23 slides down, it drives the rotating wheel 25 to rotate through meshing with the rotating wheel 25. When the rack plate 23 slides up, it drives the rotating wheel 25 to rotate in the opposite direction. When the rotating wheel 25 rotates back and forth like this, the saw teeth 24 at the front end will cut off the excess branches on the rootstock of the rotating wheel 25. Combined with the crushing treatment of the pressure plate 13, the pressure plate 13 mainly crushes the branches on the vertical section, while the saw teeth 24 can cut off the branches on the remaining cross section. The pressure plate 13 and the rotating wheel 25 work together to effectively clean up the excess branches on the cassava by-products.

[0038] As a further embodiment of the present invention, a mixer 5 is fixedly connected to the top of the simmering oven 3, a stirring paddle is provided inside the simmering oven 3, the output shaft of the mixer 5 passes through the simmering oven 3 and is fixedly connected to the stirring paddle, an exhaust hole is provided on the simmering oven 3, an air purification component is provided on one side of the simmering oven 3, and a heat insulation layer is fitted on the outer wall of the simmering oven 3.

[0039] When the above solution is put into practical use, after adding cassava by-products and soil into the oven 3, the mixer 5 drives the mixing paddle to rotate, so as to fully mix the soil and cassava by-products. During the curing process, the exhaust port can be controlled to open and close, thereby controlling the exhaust and intake. The air purification component can treat the flue gas generated during the curing process to render it harmless before it is discharged. The heat insulation layer on the outer wall of the oven 3 can effectively insulate the temperature, so that the external temperature of the oven 3 is much lower than the internal temperature.

[0040] As a further embodiment of the present invention, the material swinging assembly includes a base plate 41, which is fixedly mounted on the inner wall of the fixed frame 1. A support seat 39 is slidably connected to the rear end of the rotating wheel 25. An alignment shaft 42 is fixedly connected to the rear end of the support seat 39. The rear end of the alignment shaft 42 slides through the base plate 41 and is located behind the base plate 41. A reset spring 40 for resetting is sleeved on the alignment shaft 42. A connecting belt 38 is fixedly connected to the front end of the support seat 39. A mating sleeve 37 is fixedly connected to the front end of the connecting belt 38. The mating sleeve 37 is slidably connected to the inner wall of the fixed frame 1. A threaded rod 44 is rotatably connected to the rear side of the pressure plate 13. One end of the threaded rod 44 passes through the pressure plate 13 and is slidably connected to the inner wall of the fixed frame 1. A limit frame 43 is provided at the top of the pressure plate 13. The rear end of the limit frame 43 is fixedly connected to the threaded rod 44. A threaded sleeve 45 is spirally connected to the threaded rod 44. The threaded sleeve 45 is slidably connected to the pressure plate 13. A second torsion spring for resetting is provided inside the pressure plate 13.

[0041] When the above solution is put into practical use, if the tail end of the cassava by-product is clamped and fixed by the compression block 16 and the first conveyor belt 8 while the pressure plate 13 is at the bottom, the larger branches on the clamped and fixed cassava root are sliding horizontally relative to the pressure plate 13 because the root is sliding above the pressure plate 13. This may restrict the upward sliding of the pressure plate 13. When the pressure plate 13 returns to its original position, the limitation caused by the branches will cause the pressure plate 13 to rotate around the threaded rod 44, thereby causing the threaded sleeve 45 to rotate as well. The threaded sleeve 45 rotates and slides one end of the threaded rod 44. After the threaded rod 44 slides to the bottom with the pressure plate 13, it is located inside the mating sleeve 37. The opening at the top of the mating sleeve 37 does not restrict the sliding of the threaded rod 44. However, when the extended threaded sleeve 45 slides upward with the threaded rod 44, it is restricted inside the mating sleeve 37 due to the insufficient size of the opening at the top of the mating sleeve 37. This causes the threaded sleeve 45 to pull the mating sleeve 37 upward together with the pressure plate 13. The mating sleeve 37 pulls the support base 39 to slide through the connecting belt 38. The support base 39 is inside the fixed frame 1. The wall is horizontally sliding, causing the support seat 39 to slide horizontally inside the fixed frame 1 by the connecting belt 38, thus stretching the return spring 40. When the pressure plate 13 is gradually rotated and raised by the branch, the pressure plate 13 slides upward to the position where it is disengaged from the branch. Under the elastic force of the second torsion spring inside the pressure plate 13, the pressure plate 13 is reset. At this time, the pressure plate 13 causes the threaded sleeve 45 to reverse, causing the threaded sleeve 45 to slide back to the initial position along the threaded rod 44. That is, the threaded sleeve 45 will disengage from the mating sleeve 37 again. After losing the support of the threaded sleeve 45, the return spring 40 will return to the initial position. Under the action of its own gravity, the docking sleeve 37 resets, and the reset spring 40 pushes the support seat 39 and the rotating wheel 25 to release the elastic force and make reciprocating motion, so that the saw teeth 24 at the front end of the rotating wheel 25 reciprocate synchronously. The advantage of doing this is that when the rotating wheel 25 drives the saw teeth 24 to rotate and cut the branch, after encountering a relatively thick branch and driving the pressure plate 13 to rotate, when the pressure plate 13 resets and the saw teeth 24 contacts the branch, it can improve the sawing effect on the branch by the impact of the horizontal reciprocating sliding of the saw teeth 24 while rotating and sawing. The effect is better when sawing relatively thick branches.

[0042] As a further embodiment of the present invention, a bucket 7 is rotatably connected to the top of the simmering oven 3, and a second feed port 6 for docking with the bucket 7 is opened on the top of the simmering oven 3. The tops of the first feed port 4 and the second feed port 6 are respectively fastened with sealing caps.

[0043] When the above scheme is put into actual use, when adding soil into the furnace 3, the bucket 7 can be controlled to scoop soil and send it into the furnace 3 through the second feed port 6. Since a large amount of soil is required when preparing carbon soil, the bucket 7 can quickly add soil into the furnace 3.

[0044] A method for preparing cassava charcoal, using a cassava charcoal preparation apparatus, includes the following steps:

[0045] Step 1: After the waste cassava by-products are air-dried, they are put into the fixed frame 1. Inside the fixed frame 1, the cassava by-products are initially crushed by the pre-crushing and conveying mechanism to obtain crushed material 1.

[0046] Step 2: The obtained fragment 1 is fed into the crushing chamber 2 and crushed again by the primary crushing wheel 10 to obtain fragment 2; then it is transported to the interior of the stoking furnace 3 by the third conveyor belt 12.

[0047] Step 3: Add an appropriate amount of soil to the inside of the simmering oven 3 along with the crushed material 2 that was added to the simmering oven 3 in Step 2, and simmer inside the simmering oven 3;

[0048] Step 4: After the curing is complete, remove the product from the discharge port at the bottom of the curing furnace 3. After cooling, you can obtain cassava charcoal.

[0049] Working principle: When crushing cassava by-products, the air-dried cassava by-products are placed on the first conveyor belt 8. It is important to note that when placing the cassava by-products, the tail end of the rootstock should be placed on the first conveyor belt 8, with the branched end facing forward. This is to ensure that the pressing block 16 contacts and restricts the tail end before separating the branched end during transport. The cassava by-products are then transported through the first conveyor belt 8 to the fixed frame 1. The drive device rotates the transmission belt 14, and the rotation speed of the transmission belt 14 is consistent with the transmission speed of the first conveyor belt 8. When the cassava by-products slide to the bottom of the transmission belt 14, the pressing block 16 on the transmission belt 14 will rotate with the transmission belt 14. The sliding seat 17 contacts the cassava byproduct, and the contact pressure gradually increases with the rotation of the transmission track 14, causing the sliding seat 17 to retract onto the fixed plate 18 and compress the fixing spring. Since the transmission track 14 and the first conveyor belt 8 rotate at the same speed, the rootstock is fixed by the squeezing block 16, which restricts the position of the rootstock and transports it. While the transmission track 14 rotates through the rotating roller 15, it drives the transmission wheel 19 to rotate together through the transmission belt 21, causing the lever 20 to contact the docking rod 35. As the lever 20 rotates, it pushes the docking rod 35 to slide forward. The docking rod 35 drives the second toothed plate 34 to slide together. The second toothed plate 34 drives the transmission gear 33 to rotate, and the transmission gear 33 simultaneously drives the first toothed plate 31. The first toothed plate 31 and the second toothed plate 34 slide in opposite directions. The first toothed plate 31 and the second toothed plate 34 drive the first rotating rod 30 and the second rotating rod 36 to rotate, causing the bottom pressure plate 13 to slide downward. When the lever 20 rotates to the position where it is no longer in contact with the docking rod 35, a first torsion spring fixedly connected to the bottom of the transmission gear 33 is sleeved on the connecting shaft 32. As the transmission gear 33 rotates, the first torsion spring gradually increases its pressure. After being released from the pressure of the lever 20, the first torsion spring drives the transmission gear 33 to reverse, causing the first toothed plate 31 and the second toothed plate 34 to reset, thereby driving the pressure plate 13 to reset upward. This forms an up-and-down cycle of the pressure plate 13 until the lever 20 rotates again. At the contact point with the connecting rod 35, as the rotating wheel 25 reciprocates, the saw teeth 24 at its front end will cut off the excess branches on the rootstock of the rotating wheel 25. This, combined with the crushing treatment of the pressure plate 13, which mainly crushes the branches on the vertical section, and the saw teeth 24, which can cut off the branches on the remaining cross section, results in the crushed product entering the crushing chamber 2. After being crushed again by the primary crushing wheel 10, it is transported to the inside of the cassava oven 3 via the third conveyor belt 12. An appropriate amount of soil is added to the inside of the cassava oven 3 to mix with the cassava by-products entering the cassava oven 3. The cassava oven 3 is then cassava-cooked inside. After cassava-cooking is completed, the cassava-cooked charcoal can be removed from the discharge port at the bottom of the cassava oven 3.
