Description

Technical Field

[0001] This invention relates to the field of biochar preparation technology, specifically to a highly efficient biochar preparation device and process. Background Technology

[0002] Biochar is a type of refractory, stable, highly aromatic, carbon-rich solid material produced by the slow pyrolysis of biological residues under anaerobic conditions at high temperatures. Biochar possesses characteristics such as high and stable carbon content, high pH value, porous structure, and large specific surface area, attracting increasing attention both domestically and internationally for soil improvement and greenhouse gas emission reduction. Studies have also shown that applying biochar to soil has a positive effect on improving nitrogen use efficiency in gramineous crops such as wheat, rice, corn, and forage grasses, such as reducing nitrate leaching and decreasing N2O release from the soil. As a novel material, biochar is widely available, inexpensive, and possesses excellent properties. Furthermore, its stable structure makes it an ideal soil carbon sequestration material and a viable option for environmental remediation technologies.

[0003] Existing biochar preparation equipment requires three steps in the process: crushing, charring, and cooling of biomass raw materials. This process is cumbersome and has low efficiency. Furthermore, the crushing and heating of biomass raw materials are not thorough or uniform during the charring process, resulting in poor quality biochar. Additionally, the process involves significant heat loss and high energy consumption.

[0014] A process for a highly efficient biochar preparation device, characterized by comprising the following steps:

[0015] Step 1: Pour the biomass raw materials into the installation box, and then start the preparation equipment;

[0016] Step 2: Flip the receiving box into the bottom of the mounting platform. Then, the preparation equipment discharges the prepared biochar into the receiving box through the second discharge pipe to obtain biochar.

[0017] Step 3: Package the biochar from Step 2 to obtain the finished biochar product.

[0018] The beneficial effects of this invention are:

[0019] (1) By placing biomass raw materials into the installation box, the straw is then thoroughly crushed by the crushing mechanism inside the installation box. After crushing, the straw enters the bottom of the installation box and then enters the charcoal-making mechanism for thorough charcoal production. After charcoal production, the produced charcoal enters the cooling mechanism and is then rapidly cooled to obtain qualified biochar. This achieves integrated processing and production of biochar, greatly improving the efficiency of biochar production. At the same time, the synchronous operation of the crushing mechanism, charcoal-making mechanism, and cooling mechanism further greatly improves the efficiency of biochar production and enhances the high efficiency of the equipment.

[0020] (2) The biomass raw material is crushed by the crushing blade through the first transmission pipe and the first transmission shaft. At the same time, the crushed material is lifted by the first screw rod and then blown by the air outlet pipe, so that the biomass raw material and the crushing blade can be in full contact, which greatly improves the crushing effect of the biomass raw material, facilitates subsequent charcoal production, and thus improves the quality of biochar after subsequent charcoal production.

[0021] (3) The biomass crushed material entering the installation box is lifted into the charcoal making box by a bucket elevator for uniform and sufficient rapid charcoal making. At the same time, the crushed biomass raw material insulates the charcoal making box, reducing heat loss from the charcoal making box. Meanwhile, the heat of the charcoal making box heats the crushed biomass raw material, which facilitates subsequent charcoal making and reduces heating time. This further improves the efficiency of biomass raw material charcoal making and also reduces heat loss, thus improving the environmental friendliness of the biomass raw material charcoal making equipment.

[0022] (4) After charring, the biochar enters the cooling box, and then heat is introduced into the installation box through the heat exhaust pipe to heat the crushed material and realize energy recovery. At the same time, the cooling pipe is driven to rotate through the second transmission mechanism. Then, water is pumped into the cooling bend through the water cooling box, pipe and water pump for circulation, thereby realizing rapid cooling of the biochar after charring. At the same time, no convection air enters during the cooling process, so that moisture in the air will not enter the biochar and cause the biochar to become damp, thereby improving the production efficiency and quality of biochar.

The first transmission pipe 11 drives the first transmission shaft 14 to rotate via the first gear 12 and the second gear 13. The first transmission pipe 11 and the first transmission shaft 14 drive the crushing blade 15 to rotate, which fully crushes the biomass raw material. At the same time, the first gear 12 drives the third gear 192 to rotate, which in turn drives the first screw rod 193 to rotate. The first screw rod 193 lifts the crushed biomass raw material in the mounting box 3 upwards. Meanwhile, gas is intermittently supplied to the first connecting pipe 190 through the blower 191 and the pipeline. The gas enters the first transmission pipe 11 through the first connecting pipe 190. The gas then enters the outlet pipe 16 through the first transmission pipe 11. Under the action of air pressure, the baffle 17 inside the outlet pipe 16 is pushed open, the baffle 17 rotates, the spring 18 is compressed, and then the gas is ejected through the outlet pipe 16, blowing the crushed biomass raw material lifted by the first screw rod 193, so that the crushed biomass raw material comes into contact with the crushing blade 15 again for crushing, thereby achieving full crushing of the biomass raw material, greatly improving the crushing effect of the biomass raw material, facilitating subsequent charcoal production, and thus improving the quality of the biochar produced. Then, by opening the electric valve on the first discharge pipe 195, the crushed biomass raw material enters the mounting box 3 below the partition 194.

[0039] Example 3

[0040] Please see Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 8As shown, the charcoal-making mechanism includes a support pipe 31 rotatably connected to the cooling box 2. An electric valve is installed on the support pipe 31. A first transmission mechanism connected to the cooling box 2 is driven to the outer surface of the support pipe 31. A charcoal-making box 32 is fixedly connected to the outer surface of the support pipe 31. A transmission box 33 rotatably connected to the charcoal-making box 32 is fixedly connected to the bottom end of the first transmission pipe 11. An installation pipe 34 rotatably connected to the charcoal-making box 32 is fixedly connected to the bottom of the transmission box 33. Multiple connecting boxes 35 are fixedly connected to the outer surface of the installation pipe 34. A second motor 36 is fixedly connected inside the transmission box 33. The output end of the second motor 36 is fixedly connected to a second transmission shaft rotatably connected to the connecting box 35 via a coupling. 37.

An electric valve is fixedly connected to the output end of the bucket elevator 392. The crushed biomass raw materials entering the mounting box 3 are fed into the charcoal making box 32 by the bucket elevator 392. Then, the electric valve at the output end of the bucket elevator 392 is closed, so that the charcoal making box 32 is in a sealed state. To prevent air from entering, the material is then heated by the motor heating plate 391 to carbonize the incoming pulverized biomass raw material. Simultaneously, the pulverizing mechanism continues to operate. The first transmission pipe 11 drives the transmission box 33 to rotate, which in turn drives the mounting pipe 34 and connecting box 35 to rotate. The connecting box 35 then drives the electric heating plate 391 and the second spiral rod 390 to rotate, stirring and heating the raw material in the charcoal-making box 32. Simultaneously, the second motor 36 drives the second transmission shaft 37 to rotate. The second transmission shaft 37, through the first bevel gear 38 and the second bevel gear 39, drives the second spiral rod 390 to rotate in both directions. The second spiral rod 390 moves the pulverized raw material left and right, thus causing the pulverized raw material in the charcoal-making box 32 to move in both directions. The material is heated evenly and thoroughly by the electric heating plate, greatly improving the charring effect of biomass raw materials. Simultaneously, the raw material pulverized by the crushing mechanism enters the mounting box 3 and wraps around the outside of the charring box 32, providing insulation and reducing internal temperature loss. This also heats the freshly pulverized biomass raw material, facilitating subsequent charring and further improving the efficiency of biomass charring. It also reduces heat loss, enhancing the environmental friendliness of the biomass charring equipment. Furthermore, the first transmission mechanism drives the support pipe 31 and the charring box 32 to rotate, causing the bucket elevator 392 on the surface of the charring box 32 to fully lift the pulverized biomass raw material from the mounting box 3 into the charring box 32.Simultaneously, the charcoal-making box 32 drives the bucket elevator 392 to rotate, which also stirs the crushed biomass raw materials in the mounting box 3, ensuring thorough and uniform heating and improving heating uniformity. After the crushed biomass raw materials are charred, the electric valve on the support pipe 31 is opened, and the charred biomass then enters the cooling box 2 through the support pipe 31 for cooling.

[0042] Example 4

[0043] Please see Figure 2 , Figure 3 , Figure 5As shown, the cooling mechanism includes a cooling pipe 51 rotatably connected to the cooling tank 2. A cooling bend 52 is fixedly connected to the outer surface of the cooling pipe 51. A second connecting pipe 53 is rotatably connected to both the top and bottom ends of the cooling pipe 51. The two second connecting pipes 53 are fixedly connected to the cooling tank 2 and the mounting platform 1, respectively. The ends of the two second connecting pipes 53 that are far apart from each other are fixedly connected to a water-cooled tank 54 on the mounting platform 1 via pipes.

The prepared biochar is passed through a support pipe 3. 1. The biochar enters the cooling box 2. Then, by opening the electric valve on the heat exhaust pipe 71, the heat from the biochar entering the cooling box 2 enters the installation box 3 through the heat exhaust pipe 71, heating the crushed material in the installation box 3, thus recovering the heat again. Then, the electric valve on the heat exhaust pipe 71 is closed. Then, the second transmission mechanism drives the cooling pipe 51 to rotate, and the cooling pipe 51 drives the cooling bend 52 to rotate. At the same time, the water cooling box 54 pumps water into the second connecting pipe 53 and the cooling pipe 51 through the water pump 55 and the pipeline. Then, the water flows back into the cooling pipe 51 and the water cooling box 54 through the cooling bend 52. The cooling water entering the cooling bend 52 stirs the biochar and cools it, thus achieving rapid cooling of the biochar after charring. At the same time, no convection air enters during the cooling process, so that moisture in the air will not enter the biochar and cause it to become damp, thereby improving the production efficiency and quality of biochar.

[0045] Example 5

[0046] A process for a highly efficient biochar preparation device, characterized by comprising the following steps:

[0047] Step 1: Pour the biomass raw materials into the installation box 3, and then start the preparation equipment;

[0048] Step 2: Flip the receiving box into the bottom of the mounting platform 1, and then the preparation equipment discharges the prepared biochar into the receiving box through the second discharge pipe 56 to obtain biochar;

[0049] Step 3: Package the biochar from Step 2 to obtain the finished biochar product.

[0050] The working principle of this invention is as follows: Biomass raw materials are placed into the installation box 3. A drive mechanism rotates the first transmission pipe 11, which in turn drives the first transmission shaft 14 via the first gear 12 and the second gear 13. The first transmission pipe 11 and the first transmission shaft 14 then drive the pulverizing blade 15, which thoroughly pulverizes the biomass raw materials. Simultaneously, the first gear 12 drives the third gear 192, which in turn drives the first screw rod 193. The first screw rod 193 lifts the pulverized biomass raw materials upwards from the installation box 3. At the same time, a blower 191 and a pipeline intermittently supply gas into the first connecting pipe 190. The gas enters the... The gas enters the first transmission pipe 11 and then the gas enters the outlet pipe 16. Under the action of air pressure, the baffle 17 in the outlet pipe 16 is pushed open, the baffle 17 rotates, the spring 18 is compressed, and then the gas is ejected through the outlet pipe 16, blowing the crushed biomass raw material lifted by the first screw rod 193, so that the crushed biomass raw material comes into contact with the crushing blade 15 again for crushing, thereby achieving full crushing of the biomass raw material, greatly improving the crushing effect of the biomass raw material, facilitating subsequent charcoal production, and thus improving the quality of the biochar produced. Then, by opening the electric valve on the first discharge pipe 195, the crushed biomass raw material enters the mounting box 3 below the partition 194.

[0051] The pulverized biomass raw materials entering the installation box 3 are fed into the charcoal-making box 32 via a bucket elevator 392. The electric valve at the output end of the bucket elevator 392 is then closed to seal the charcoal-making box 32 and prevent air from entering. The raw materials are then heated by a motor-heated plate 391 to carbonize them. Simultaneously, the pulverizing mechanism continues to operate. The first transmission pipe 11 drives the transmission box 33 to rotate, which in turn drives the installation pipe 34 and the connecting box 35 to rotate. The connecting box 35 then drives the electric heating plate 391 and the second screw rod 390 to rotate, stirring and heating the raw materials in the charcoal-making box 32. Simultaneously, the second motor 36 drives the second transmission shaft 37 to rotate. The second transmission shaft 37, through the first bevel gear 38 and the second bevel gear 39, drives the second screw rod 390 to rotate in both directions. The second screw rod 390 moves the pulverized raw materials left and right, ensuring that the pulverized raw materials in the charcoal-making box 32 are heated evenly by the electric heating plate, thus greatly improving the carbonization efficiency. To improve the charcoal production effect of biomass raw materials, the raw materials crushed by the crushing mechanism enter the installation box 3 and wrap around the outside of the charcoal making box 32, which insulates the charcoal making box 32 and reduces the loss of internal temperature. At the same time, it heats the freshly crushed biomass raw materials, which is convenient for subsequent charcoal production, thereby further improving the efficiency of biomass raw material charcoal production and reducing heat loss, thus improving the environmental protection of biomass raw material charcoal production equipment. At the same time, the first transmission mechanism drives the support pipe 31 and the charcoal making box 32 to rotate, so that the bucket elevator 392 on the surface of the charcoal making box 32 can fully lift the crushed biomass raw materials in the installation box 3 into the charcoal making box 32. At the same time, the rotation of the bucket elevator 392 driven by the charcoal making box 32 also stirs the crushed biomass raw materials in the installation box 3, so that they are fully and evenly heated, improving the heating uniformity. After the crushed biomass raw materials are charcoaled, the electric valve on the support pipe 31 is opened, and then the charcoal produced enters the cooling box 2 through the support pipe 31 for cooling.

[0052] The prepared biochar enters the cooling box 2 through the support pipe 31. Then, by opening the electric valve on the heat exhaust pipe 71, the heat from the biochar entering the cooling box 2 is transferred through the heat exhaust pipe 71 into the installation box 3, heating the crushed material in the installation box 3 and thus recovering the heat again. Afterward, the electric valve on the heat exhaust pipe 71 is closed, and the second transmission mechanism drives the cooling pipe 51 to rotate. The cooling pipe 51 drives the cooling bend 52 to rotate. At the same time, the water cooling box 54 pumps water into the second connecting pipe 53 and the cooling pipe 51 through the water pump 55 and the pipeline. Then, the water flows back into the cooling pipe 51 and the water cooling box 54 through the cooling bend 52. The cooling water entering the cooling bend 52 stirs the biochar and cools it, thus achieving rapid cooling of the biochar after charring. At the same time, no convective air enters during the cooling process, so that moisture in the air will not enter the biochar and cause it to become damp, thereby improving the production efficiency and quality of the biochar.

[0053] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention.
