Description

Technical Field

[0001] The present invention relates to the technical field of biochar processing, and more specifically, to a pulverizing device for biochar processing and a method for using the pulverizing device. Background Art

[0002] Biochar is a carbonaceous material produced by pyrolysis of biomass raw materials under oxygen-deficient or limited oxygen conditions. Common biomass raw materials include crop residues (such as straw, wheat straw, corn stalks), forestry waste, food processing waste (such as fruit shells, fruit residues, bean dregs) and other organic wastes. Biochar has a wide range of applications in agriculture, environmental governance, energy and other fields due to its high specific surface area, rich pore structure and good adsorption properties.

[0003] In order to improve the pyrolysis efficiency of biochar, it is usually necessary to crush the biomass raw materials. Crushing can significantly increase the total surface area of ​​the raw materials, so that the materials can be heated more evenly during the pyrolysis process, thereby improving the rate and efficiency of the pyrolysis reaction. In addition, the crushed materials are easier to pass through the feeding system, avoiding equipment blockage caused by large pieces of materials, and can reduce heat transfer resistance and optimize pyrolysis conditions.

[0004] In horticultural applications, in order to provide a suitable growth environment for plants in pots or flower pots, it is necessary to provide nutrients of multiple elements. Traditionally prepared biochar is mainly made by pulverizing a single biomass raw material (such as crop residues) and then pyrolyzing it. Although this type of biochar has a certain soil improvement effect, it is difficult to meet the plant's needs for multiple nutrients due to its single composition. Summary of the invention

[0046] The following is a detailed description of a biochar processing pulverizing device and a method of using the same provided by the present invention in conjunction with the accompanying drawings and specific embodiments. At the same time, it is explained here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art may also adopt other alternative methods to implement some known technologies; and the accompanying drawings are only for a more specific description of the embodiments, and are not intended to specifically limit the present invention.

[0047] like Figures 1 to 7 As shown, an embodiment of the present invention provides a pulverizing device for biochar processing, comprising a pulverizing box 1, a supporting foot is fixedly connected to the bottom of the pulverizing box 1, a top plate 2 is fixedly connected to the top of the pulverizing box 1, a feeding port is opened in the middle of the top plate 2, a pulverizing cylinder 3 for storing crop residues is arranged in the middle of the pulverizing box 1; and a pulverizing mechanism 6 for pulverizing the crop residues is arranged in the pulverizing cylinder 3, partitions 5 fixedly connected to the inner wall of the pulverizing box 1 are arranged on both sides of the outer surface of the pulverizing cylinder 3, and semicircular arc plates 7 are arranged between the partitions 5 and the pulverizing cylinder 3, a pulverizing mechanism 8 for pulverizing food processing waste is arranged at the top of the pulverizing box 1, and a mixing mechanism 9 for secondary pulverization and mixing of the pulverized crop residues and food processing waste is arranged at the bottom of the pulverizing cylinder 3;

[0048] The crushing mechanism 8 includes a second servo motor 81 fixedly connected to the front side of the outer surface of the crushing box 1, and the output end of the second servo motor 81 is fixedly connected to the first rotating rod 82;

[0049] Among them, the mixing mechanism 9 includes a main gear 95 fixedly connected to the outer circumferential surface of the first rotating rod 82, and a gear ring 91 meshing with the main gear 95 is commonly provided in the middle of the partition 5 and the semicircular arc plate 7. The inner bottom of the crushing box 1 is rotatably connected with evenly distributed support rods 92, and the outer circumferential surfaces of the support rods 92 are fixedly connected with impellers 93 for secondary crushing and mixing of crushed crop residues and food processing waste. Both ends of the outer circumferential surface of the support rods 92 are fixedly connected with driven gears 94 meshing with the gear ring 91.

[0050] In order to solve the problem of raw material homogeneity in the existing biochar preparation process, the above technical solution is adopted to solve the problem. The above technical solution is mainly composed of a crushing mechanism 8 and a mixing mechanism 9. When preparing biochar, the required food processing waste, such as fruit shells, is first poured into the crushing box 1 from the feeding port of the top plate 2. At the same time, crop residues, such as corn stalks, can be sent to the crushing cylinder 3 and crushed by the crushing mechanism 6. In the process of crushing the fruit shells, the second servo motor 81 is started, so that the first rotating rod 82 drives the main gear 95 to rotate, so that the meshing gear ring 91 rotates synchronously. The rotation of the gear ring 91 drives the meshing driven gear 94 to rotate synchronously, so that the support rod 92 drives the impeller 93 to rotate in the crushing box 1, so as to further stir and mix the crushed fruit shell powder residue. After the corn stalks are crushed for a period of time, the discharge port of the crushing cylinder 3 is opened to allow the processed corn stalks to fall into the bottom of the crushing box 1. The impeller 93 is used to crush and mix the processed corn stalks with the husk powder residue that falls into the bottom of the crushing box 1 to form a new mixed raw material. The biochar raw material prepared by this process has a higher nutrient diversity than the traditional biochar raw material, thereby improving the soil improvement effect of biochar and meeting the plant's needs for multiple nutrients. At the same time, the device not only improves the pyrolysis efficiency of biochar, but also prepares biochar with multiple nutrients by mixing different types of biomass raw materials, making its application in horticulture and other fields more extensive and effective.

[0051] like Figure 1 , Figure 4 , Figure 5As shown, the pulverizing mechanism 8 also includes a second rotating rod 86 rotatably connected to one side of the top of the pulverizing box 1, a second crushing roller 87 is fixedly connected to the middle of the outer circumferential surface of the second rotating rod 86, and both ends of the outer surface of the second crushing roller 87 are provided with second gears 85 fixedly connected to the second rotating rod 86, the first rotating rod 82 passes through the pulverizing box 1 and the partition 5 and is fixedly connected to the first crushing roller 83, and both sides of the outer surface of the first crushing roller 83 are provided with first gears 84 fixedly connected to the first rotating rod 82; and through the meshing transmission of the first gear 84 and the second gear 85, the first crushing roller 83 and the second crushing roller 87 can work together to crush the food processing waste.

[0052] like Figure 4 , Figure 5 As shown, the inner and outer surfaces of the gear ring 91 are both provided with latching teeth, and the outer latching teeth are meshed and connected with the main gear 95 , while the inner latching teeth are meshed and connected with the driven gear 94 .

[0053] In order to solve the problem that some fruit shells are not completely crushed due to too fast feeding during the existing fruit shell crushing process, the above technical solution is adopted to solve the problem. The above technical solution is mainly composed of a crushing mechanism 8 and a mixing mechanism 9. When the fruit shell crushing operation is performed, the second servo motor 81 is first started to rotate forward, so that the first rotating rod 82 drives the first gear 84 to rotate clockwise. The clockwise rotation of the first gear 84 drives the second gear 85 to rotate counterclockwise through meshing connection, and then the second rotating rod 86 rotates counterclockwise. The second rotating rod 86 drives the second crushing roller 87 to rotate counterclockwise in the crushing box 1, and at the same time, the first rotating rod 82 drives the first crushing roller 83 to rotate clockwise. The first crushing roller 83 and the second crushing roller 87 rotate with each other, so that the fruit shells passing through the gap between the two are crushed. The uncrushed fruit shells will fall into the bottom of the crushing box 1. When the uncrushed fruit shells fall into the bottom of the crushing box 1, the rotation of the main gear 95 drives the gear ring 91 meshed with it to rotate synchronously. The rotation of the gear ring 91 drives the driven gear 94 meshing with its internal teeth to rotate synchronously. The rotation of the driven gear 94 causes the support rod 92 to drive the impeller 93 to rotate in the crushing box 1, and the impeller 93 is used to crush the uncrushed husks, avoiding the situation where the husks are not completely crushed and the mixing effect is poor. At the same time, the impeller 93 can also be used to stir the preliminarily crushed husks and the processed corn stalks, further ensuring that the quality of the subsequent mixed raw materials is better, thereby improving the improvement effect of biochar on the soil and meeting the needs of plants for multiple nutrients.

[0054] like Figure 1 , Figure 2 , Figure 4 , Figure 6As shown, a feed hopper 4 fixedly connected to the crushing cylinder 3 is provided on one side of the interior of the crushing box 1, and the crushing mechanism 6 includes a crushing roller 63 rotatably connected to the interior of the crushing cylinder 3, and a first servo motor 61 is fixedly connected to the front side of the outer surface of the crushing box 1, and a driving rod 62 for driving the crushing roller 63 to rotate is fixedly connected to the output end of the first servo motor 61.

[0055] like Figure 1 , Figure 4 , Figure 6 As shown, a first material discharge slot is provided at the bottom of the crushing cylinder 3; and a first arc-shaped sealing plate 64 is provided at the position of the first material discharge slot, one side of the first arc-shaped sealing plate 64 is slidably connected to the inside of the crushing cylinder 3, and both ends of one side of the first arc-shaped sealing plate 64 are fixedly connected to an electric telescopic rod 66, and one end of the electric telescopic rod 66 is provided with a U-shaped plate 65 fixedly connected to the front side of the outer surface of the crushing box 1.

[0056] When it is necessary to grind crop residues such as corn stalks, the corn stalks are fed from the feed hopper 4 into the grinding cylinder 3. The first servo motor 61 is started, so that the driving rod 62 drives the grinding roller 63 to rotate in the grinding cylinder 3. The grinding roller 63 is used to grind the corn stalks in the grinding cylinder 3. The grinding roller 63 cuts the corn stalks into smaller particles through high-speed rotation and shearing. After the corn stalks are ground for a period of time, the electric telescopic rod 66 is started to be in a contracted state, so that the first arc-shaped sealing plate 64 is pulled out from the first discharge slot at the bottom of the grinding cylinder 3. The ground corn stalks fall from the first discharge slot to the bottom of the crushing box 1. The ground corn stalks and the crushed fruit shells that fall to the bottom of the crushing box 1 can be further ground and mixed by the stirring action of the impeller 93. Through the above technical solution, the crop residues such as corn stalks can be effectively crushed and mixed with crushed food processing waste such as husks. This mixing process not only improves the pyrolysis efficiency of biochar, but also prepares biochar with multiple nutrients, making its application in horticulture and other fields more extensive and effective.

[0057] like Figure 1 , Figure 6As shown, the top of the outer cylindrical surface of the crushing cylinder 3 is provided with evenly distributed leakage holes 31, and the top of the outer cylindrical surface of the crushing cylinder 3 is provided with an anti-blocking mechanism 10 for unblocking the leakage holes 31. The anti-blocking mechanism 10 includes a third servo motor 101 fixedly connected to the front side of the outer surface of the crushing box 1, and the output end of the third servo motor 101 is fixedly connected to a threaded rod 102. The top of the outer cylindrical surface of the crushing cylinder 3 is provided with a sliding rod 104 fixedly connected to the crushing box 1, and one end of the outer cylindrical surface of the sliding rod 104 is slidably connected to a sliding seat 105, and the bottom of the sliding seat 105 is fixedly connected to a brush 106 for unblocking the leakage holes 31, and a spiral sleeve 103 spirally connected to the threaded rod 102 is provided on one side of the top of the brush 106.

[0058] like Figure 6 As shown, the outer shell of the brush 106 is arc-shaped, and the output end of the brush 106 fits with the outer circumferential surface of the crushing cylinder 3.

[0059] In the process of crushing the corn stalks by the crushing roller 63, the small-particle husk powder residue that falls will enter the crushing cylinder 3 through the leakage hole 31, and be further mixed and crushed with the corn stalks. However, the leakage hole 31 will be blocked after long-term use. Therefore, the threaded rod 102 is rotated by starting the third servo motor 101 forward and reverse. The rotation of the threaded rod 102 causes the spiral sleeve 103 connected to it to rotate synchronously. Due to the limiting effect of the slide bar 104 and the slide seat 105, the brush 106 reciprocates on the threaded rod 102, and the leakage hole 31 of the crushing cylinder 3 is cleared by the brush 106, ensuring that the small-particle husk powder residue can enter the crushing cylinder 3 through the leakage hole 31 normally to be further mixed with the corn stalks. At the same time, the large-particle husk powder residue and the uncrushed husk remaining on the top of the crushing cylinder 3 can be scraped off to the bottom of the crushing box 1 by the brush 106. These large-particle fruit shell powder residues and un-crushed fruit shells will be further crushed at the bottom of the crushing box 1, reducing the waste of fruit shells and making the prepared mixed raw material more fine.

[0060] like Figure 2 , Figure 3 As shown, both sides of the crushing cylinder 3 and the first crushing roller 83 and the second crushing roller 87 are provided with partitions 5 for dividing the crushing box 1 into a plurality of cavities.

[0061] When preparing the biochar raw material, the crushing box 1 is divided into a plurality of independent cavities by setting the partition 5. The cavity formed by the adjacent partitions 5 can temporarily store large-particle husk powder residue and uncrushed husk and corn stalks. The impeller 93 is used to further crush and mix the mixed raw materials stored in the bottom cavity of the crushing box 1. Through the stirring action of the impeller 93, different types of biomass raw materials such as husk powder residue and corn stalks can be evenly mixed to improve the quality of the final biochar. At the same time, the partition 5 can block the powder residue that falls during the crushing process to prevent it from splashing onto the first gear 84, the second gear 85 and the gear ring 91 required by the crushing mechanism 8. This blocking effect helps to keep the transmission components clean, prevents the powder residue from entering the gear meshing part, and affects the transmission effect between them, thereby ensuring the normal operation of the equipment.

[0062] like Figure 1 , Figure 7 As shown, a fixing plate 11 is fixedly connected at the four corners of the bottom of the crushing box 1, a second discharge slot is opened in the middle of the bottom of the crushing box 1, a second arc-shaped sealing plate 12 is arranged at the position of the second discharge slot, and both ends of the outer circular surface of the second arc-shaped sealing plate 12 are fixedly connected with a T-shaped support plate 13, and both ends of the T-shaped support plate 13 are provided with pins for limiting.

[0063] After the raw material preparation is completed by the impeller 93, the latch is removed from the inside of the T-shaped support plate 13 and the fixed plate 11. The function of the latch is to limit the position of the second arc-shaped sealing plate 12 to prevent it from accidentally moving during the crushing process. After the latch is removed, the second arc-shaped sealing plate 12 is pulled out from the bottom of the crushing box 1 to open the second discharge slot. The mixed raw materials are discharged from the second discharge slot to facilitate unified collection by external collection equipment.

[0064] The method of use provided by the present invention is as follows:

[0065] S1: Pour the required food processing waste into the crushing box 1 from the discharge port of the top plate 2, and use the first crushing roller 83 and the second crushing roller 87 to rotate relative to each other, so that the fruit shells passing through the gap between the two are crushed, and the fruit shells that are not crushed will fall into the bottom of the crushing box 1;

[0066] S2: When the uncrushed husks fall into the bottom of the crushing box 1, the rotation of the main gear 95 drives the gear ring 91 to rotate synchronously, thereby driving the driven gear 94 to rotate synchronously, so that the support rod 92 drives the impeller 93 to crush the uncrushed husks and further mix them with the crushed husk powder residue;

[0067] S3: Feed corn stalks from the feed hopper 4 into the crushing cylinder 3, start the first servo motor 61, so that the driving rod 62 drives the crushing roller 63 to rotate in the crushing cylinder 3, and the crushing roller 63 is used to crush the corn stalks;

[0068] S4: After the corn stalks are crushed for a period of time, the first arc-shaped sealing plate 64 is pulled out from the first discharge slot at the bottom of the crushing cylinder 3, so that the crushed corn stalks fall from the first discharge slot to the bottom of the crushing box 1, and the crushed corn stalks are further mixed with the crushed husk powder residue by the stirring action of the impeller 93;

[0069] S5: After the raw material preparation is completed by the impeller 93, the latch is taken out, and the second arc-shaped sealing plate 12 is pulled out from the bottom of the crushing box 1, so that the mixed raw materials are discharged from the second discharge slot, which is convenient for unified collection by external collection equipment.

[0070] When the present invention is used, firstly, the required food processing waste, such as fruit shells, is poured into the crushing box 1 from the feeding port of the top plate 2, and the second servo motor 81 is started, so that the first rotating rod 82 drives the first gear 84 to rotate clockwise. The first gear 84 drives the second gear 85 to rotate counterclockwise through meshing, and then the second rotating rod 86 rotates counterclockwise. The second rotating rod 86 drives the second crushing roller 87 to rotate counterclockwise in the crushing box 1, and the first rotating rod 82 drives the first crushing roller 83 to rotate clockwise. The first crushing roller 83 and the second crushing roller 87 rotate with each other, so that the fruit shells passing through the gap between the two are crushed. The uncrushed fruit shells will fall into the bottom of the crushing box 1. When the uncrushed fruit shells fall into the bottom of the crushing box 1, the rotation of the main gear 95 drives the gear ring 91 meshed with it to rotate synchronously. The rotation of the gear ring 91 drives the driven gear 94 meshing with the internal teeth thereof to rotate synchronously, so that the support rod 92 drives the impeller 93 to rotate in the crushing box 1. The impeller 93 is used to crush the uncrushed husks and further mix them with the crushed husk powder residue. In the process of crushing the husks, the corn stalks are fed from the feed hopper 4 into the crushing cylinder 3. The first servo motor 61 is started, so that the driving rod 62 drives the crushing roller 63 to rotate in the crushing cylinder 3. The crushing roller 63 is used to crush the corn stalks. After the corn stalks are crushed for a period of time, the electric telescopic rod 66 is started to be in a contracted state, so that the first arc-shaped sealing plate 64 is pulled out from the first discharge slot at the bottom of the crushing cylinder 3. The crushed corn stalks fall from the first discharge slot to the bottom of the crushing box 1. The stirring action of the impeller 93 is used to further mix the crushed corn stalks with the crushed husk powder residue. In the process of crushing the corn stalks by the crushing roller 63, the small-particle husk powder residue that falls will enter the crushing barrel 3 through the leakage hole 31. In order to prevent the leakage hole 31 from being blocked, the third servo motor 101 is started to rotate forward and reversely, so that the threaded rod 102 rotates. The rotation of the threaded rod 102 causes the spiral sleeve 103 that is spirally connected to it to rotate synchronously. Due to the limiting effect of the slide bar 104 and the slide seat 105, the brush 106 reciprocates on the threaded rod 102, and the leakage hole 31 of the crushing barrel 3 is dredged by the brush 106. At the same time, the brush 106 can scrape the large-particle husk powder residue and the uncrushed husk remaining on the top of the crushing barrel 3 to the bottom of the crushing box 1. These large-particle husk powder residue and the uncrushed husk will be further crushed at the bottom of the crushing box 1, reducing the waste of husks and making the prepared mixed raw materials more delicate. After the raw materials are prepared by the impeller 93, the latch is removed from the inside of the T-shaped support plate 13 and the fixed plate 11. After the latch is removed, the second arc-shaped sealing plate 12 is pulled out from the bottom of the crushing box 1, thereby opening the second discharge slot. The mixed raw materials are discharged from the second discharge slot, which is convenient for the external collection equipment to collect them uniformly.

[0071] The above technical solution can effectively solve the problem of raw material homogeneity in the existing biochar preparation process and the problem that some fruit shells are not completely crushed due to too fast feeding during the crushing process. The device not only improves the pyrolysis efficiency of biochar, but also prepares biochar with multiple nutrients by mixing different types of biomass raw materials, making its application in horticulture and other fields more extensive and effective. In actual operation, it is also necessary to continuously adjust and optimize the process parameters according to the specific situation to achieve the best effect.
