Description

Technical Field

[0002] Biochar is a porous solid material produced by the pyrolysis of carbon-rich biomass under anaerobic or oxygen-deficient conditions. Medicinal herb residue is a type of biomass. Before carbonization, it requires pretreatment, such as drying and pulverizing. Currently, carbonization equipment is commonly used for medicinal herb residue. However, some existing equipment requires stopping the machine to collect the biochar, then adding more material and restarting it before resuming biochar production. This intermittent start-stop cycle makes it difficult to achieve a continuous process from pretreatment to carbonization, ultimately reducing the overall efficiency of biochar production.

[0033] Example 1

[0034] like Figure 1-10 As shown, the present invention provides a biochar production system for Chinese medicinal herb residues, including a pretreatment mechanism from an external source of Chinese medicinal herb residues, a carbonization mechanism from the pretreatment mechanism, and a collection mechanism and a recycling mechanism from the carbonization mechanism respectively. The carbonization mechanism includes a box 1, a feeding mechanism located at the top of the box 1 and connected to the pretreatment mechanism, an electric heating box 2 located inside the box 1 and connected to the feeding mechanism, and several heat transfer mechanisms arranged in parallel inside the electric heating box 2. The collection mechanism is sealed from the bottom of the electric heating box 2, and the recycling mechanism is sealed from the top of the electric heating box 2.

[0035] In this embodiment 1, the carbonization mechanism can continuously carbonize the newly added Chinese medicinal material residues. In this way, the pretreated Chinese medicinal material residues can be continuously added to the carbonization mechanism for carbonization, so that the process from pretreatment to carbonization of Chinese medicinal material residues can be continuous.

[0036] The principle behind the continuous carbonization of newly added Chinese herbal medicine residues is as follows: Several heat transfer rollers are arranged in parallel within the carbonization mechanism. After partial pyrolysis in the upper heat transfer roller, the Chinese herbal medicine residues enter the lower heat transfer roller for further pyrolysis. In this way, the Chinese herbal medicine residues are pyrolyzed and completely carbonized in each heat transfer roller in parallel order, and then temporarily stored in the temporary storage chamber. After being sealed and dropped into the cooling storage box 33 through the outlet on the upper part of the box, the Chinese herbal medicine residues are transferred from the upper heat transfer roller to the lower heat transfer roller. The interior of the upper heat transfer roller is then emptied, and the empty heat transfer roller can continue to receive Chinese herbal medicine residues transferred from its upper heat transfer roller. In this way, new medicinal residues can be continuously added to the carbonization mechanism, while the generated biomass carbon is continuously collected from the outlet of the carbonization mechanism.

[0037] This utility model has a simple structure, a scientific and reasonable design, and is easy to use. After the pretreatment mechanism pretreats the Chinese medicinal material residue, the feeding mechanism continuously adds new Chinese medicinal material residue into the box for pyrolysis. At the same time, the produced biomass carbon is continuously collected from the outlet at the bottom of the box. The process from pretreatment to carbonization of Chinese medicinal material residue is a continuous process, which improves the production efficiency of biomass carbon.

[0038] Example 2

[0039] like Figure 1-10As shown, the present invention provides a biochar production system for Chinese medicinal herb residues, including a pretreatment mechanism from an external source of Chinese medicinal herb residues, a carbonization mechanism from the pretreatment mechanism, and a collection mechanism and a recycling mechanism from the carbonization mechanism respectively. The carbonization mechanism includes a box 1, a feeding mechanism located at the top of the box 1 and connected to the pretreatment mechanism, an electric heating box 2 located inside the box 1 and connected to the feeding mechanism, and several heat transfer mechanisms arranged in parallel inside the electric heating box 2. The collection mechanism is sealed from the bottom of the electric heating box 2, and the recycling mechanism is sealed from the top of the electric heating box 2.

[0040] The pretreatment mechanism includes a dryer 30 that receives the residue from external Chinese medicinal materials, a pulverizer 31 that receives the residue from the dryer 30, a feeder 32 that receives the residue from the pulverizer 31, and a weighing hopper 42 that receives the residue from the feeder 32 and connects to the feeding mechanism.

[0041] In this embodiment 2, the dryer 30 is used to dry the moisture in the Chinese medicinal material residue, the pulverizer 31 is used to pulverize the dried Chinese medicinal material residue, and the feeder 32 is used to feed the pulverized Chinese medicinal material residue to the weighing hopper 42. The weighing hopper 42 is used to weigh a certain amount of Chinese medicinal material residue into the carbonization mechanism for carbonization.

[0042] Example 3

[0043] like Figure 1-10 As shown, the present invention provides a biochar production system for Chinese medicinal herb residues, including a pretreatment mechanism from an external source of Chinese medicinal herb residues, a carbonization mechanism from the pretreatment mechanism, and a collection mechanism and a recycling mechanism from the carbonization mechanism respectively. The carbonization mechanism includes a box 1, a feeding mechanism located at the top of the box 1 and connected to the pretreatment mechanism, an electric heating box 2 located inside the box 1 and connected to the feeding mechanism, and several heat transfer mechanisms arranged in parallel inside the electric heating box 2. The collection mechanism is sealed from the bottom of the electric heating box 2, and the recycling mechanism is sealed from the top of the electric heating box 2.

[0044] The electric heating box 2 has several mounting cavities 6 arranged in parallel, each corresponding to a heat transfer mechanism and connected to the inner cavity of the electric heating box 2. The heat transfer mechanism is located in the mounting cavity 6.

[0045] In this embodiment 3, the mounting cavity 6 is cylindrical, and the upper and lower ends of the mounting cavity 6 are respectively connected to the inner cavity of the electric heating box.

[0046] Example 4

[0047] like Figure 1-10As shown, the present invention provides a biochar production system for Chinese medicinal herb residues, including a pretreatment mechanism from an external source of Chinese medicinal herb residues, a carbonization mechanism from the pretreatment mechanism, and a collection mechanism and a recycling mechanism from the carbonization mechanism respectively. The carbonization mechanism includes a box 1, a feeding mechanism located at the top of the box 1 and connected to the pretreatment mechanism, an electric heating box 2 located inside the box 1 and connected to the feeding mechanism, and several heat transfer mechanisms arranged in parallel inside the electric heating box 2. The collection mechanism is sealed from the bottom of the electric heating box 2, and the recycling mechanism is sealed from the top of the electric heating box 2.

[0048] The electric heating box 2 has several mounting cavities 6 arranged in parallel, each corresponding to a heat transfer mechanism and connected to the inner cavity of the electric heating box 2. The heat transfer mechanism is located in the mounting cavity 6.

[0049] The heat transfer mechanism includes a shaft 4 fixedly installed in the mounting cavity 6, a heat transfer roller 3 rotatably installed on the shaft 4 to accommodate the residue of Chinese medicinal materials, and a drive mechanism installed on the housing 1 and connected to the heat transfer roller 3 to drive the heat transfer roller 3 to rotate in the electric heating box 2; the heat transfer roller 3 has a slot 5 that communicates with the inner cavity of the electric heating box 2 along its length.

[0050] In this embodiment 4, the heat transfer roller 3 is open at both ends and sealed to the inner walls of the electric heating box 2 respectively. Several dispersing rods 10 are evenly distributed on the shaft 4. The electric heating box 2 generates heat and transfers it to the heat transfer roller 3. The medicinal herb residue inside the heat transfer roller is pyrolyzed to generate biomass carbon. During the pyrolysis process, the heat transfer roller 3 rotates in both directions inside the electric heating box 2, causing the medicinal herb residue inside the roller to sway left and right. Meanwhile, the shaft 4 at the center of the heat transfer roller remains stationary. The dispersing rods 10 fixed to the shaft disperse the swaying medicinal herb residue inside the heat transfer roller, preventing its accumulation, ensuring uniform heating, and improving carbonization efficiency and quality.

[0051] When the medicinal herb residue is pyrolyzed in the heat transfer roller 3, the groove 5 on the heat transfer roller 3 faces upward. This prevents the medicinal herb residue from falling out of the heat transfer roller 3 during rotation. When the medicinal herb residue is transferred from the upper heat transfer roller 3 to the lower heat transfer roller 3, the upper heat transfer roller 3 is rotated so that the groove 5 on the upper heat transfer roller 3 faces downward and is opposite to the groove 5 on the lower heat transfer roller 3. The medicinal herb residue in the upper heat transfer roller 3 is transferred to the lower heat transfer roller 3 for further pyrolysis through the two grooves 5 that face each other between the upper and lower heat transfer rollers 3.

[0055] The heat transfer mechanism includes a shaft 4 fixedly installed in the mounting cavity 6, a heat transfer roller 3 rotatably installed on the shaft 4 to accommodate the residue of Chinese medicinal materials, and a drive mechanism installed on the housing 1 and connected to the heat transfer roller 3 to drive the heat transfer roller 3 to rotate in the electric heating box 2; the heat transfer roller 3 has a slot 5 that communicates with the inner cavity of the electric heating box 2 along its length.

[0056] A sleeve 8 is provided at each end of the heat transfer roller 3. A second sprocket 14 is connected to the sleeve 8. Several connecting rods 9 are provided between the outer wall of the sleeve 8 and the inner wall of the heat transfer roller 3. The sleeve 8 and the second sprocket 14 are movably mounted on the shaft 4. One of the second sprockets 14 is connected to the drive mechanism.

[0057] An installation through hole 7 is provided on each of the two inner side walls of the mounting cavity 6. The installation through hole 7 is adapted to the sleeve 8. The two ends of the shaft 4 pass through the two installation through holes 7 respectively and are fixedly connected to the two inner side walls of the housing 1 respectively. The sleeve 8 is inserted into the corresponding installation through hole 7.

[0058] In this embodiment 5, the sleeve 8 is fixedly connected to the second sprocket 14, and the sleeve 8 and the second sprocket 14 are respectively clearance-fitted with the shaft 4. The sleeve 8 and the second sprocket 14 are movably mounted on the shaft 4, allowing the heat transfer roller 3 to rotate on the shaft 4. The drive mechanism can drive the connected second sprocket 14 to rotate, which in turn drives the corresponding sleeve 8 to rotate, and the sleeve 8 drives the heat transfer roller 3 to rotate.

[0059] The sleeve 8 is inserted into the corresponding mounting through hole 7, and the second sprocket 14 is located outside the mounting through hole 7, so that the drive mechanism can be connected to the second sprocket 14.

[0060] Example 6

[0061] like Figure 1-10As shown, the present invention provides a biochar production system for Chinese medicinal herb residues, including a pretreatment mechanism from an external source of Chinese medicinal herb residues, a carbonization mechanism from the pretreatment mechanism, and a collection mechanism and a recycling mechanism from the carbonization mechanism respectively. The carbonization mechanism includes a box 1, a feeding mechanism located at the top of the box 1 and connected to the pretreatment mechanism, an electric heating box 2 located inside the box 1 and connected to the feeding mechanism, and several heat transfer mechanisms arranged in parallel inside the electric heating box 2. The collection mechanism is sealed from the bottom of the electric heating box 2, and the recycling mechanism is sealed from the top of the electric heating box 2.

[0062] The electric heating box 2 has several mounting cavities 6 arranged in parallel, each corresponding to a heat transfer mechanism and connected to the inner cavity of the electric heating box 2. The heat transfer mechanism is located in the mounting cavity 6.

[0063] The heat transfer mechanism includes a shaft 4 fixedly installed in the mounting cavity 6, a heat transfer roller 3 rotatably installed on the shaft 4 to accommodate the residue of Chinese medicinal materials, and a drive mechanism installed on the housing 1 and connected to the heat transfer roller 3 to drive the heat transfer roller 3 to rotate in the electric heating box 2; the heat transfer roller 3 has a slot 5 that communicates with the inner cavity of the electric heating box 2 along its length.

[0065] In this embodiment 6, the principle of the driving mechanism driving the heat transfer roller 3 to rotate is as follows: the forward and reverse motor 11 starts, the forward and reverse motor 11 drives the connecting shaft 12 to rotate, the connecting shaft 12 drives the first sprocket 13 to rotate, the first sprocket 13 drives the transmission chain 15 to move, the transmission chain 15 pulls the second sprocket 14 to rotate, the second sprocket 14 drives the corresponding sleeve 8 to rotate, and the sleeve 8 drives the heat transfer roller 3 to rotate.

[0066] A fixing through hole 27 is provided on the housing 1, and the connecting shaft 12 is sealed and passes through the fixing through hole 27.

[0067] Example 7

[0068] like Figure 1-10As shown, the present invention provides a biochar production system for Chinese medicinal herb residues, including a pretreatment mechanism from an external source of Chinese medicinal herb residues, a carbonization mechanism from the pretreatment mechanism, and a collection mechanism and a recycling mechanism from the carbonization mechanism respectively. The carbonization mechanism includes a box 1, a feeding mechanism located at the top of the box 1 and connected to the pretreatment mechanism, an electric heating box 2 located inside the box 1 and connected to the feeding mechanism, and several heat transfer mechanisms arranged in parallel inside the electric heating box 2. The collection mechanism is sealed from the bottom of the electric heating box 2, and the recycling mechanism is sealed from the top of the electric heating box 2.

[0069] An insulation cavity 21 is formed between the outer wall of the electric heating box 2 and the inner wall of the box body 1. An air inlet pipe 22 and an air outlet pipe 23, which are respectively connected to the insulation cavity 21, are connected to the box body 1. An air valve 24 is provided on the air inlet pipe 22 and the air outlet pipe 23 respectively. A fan 43 is connected to the air inlet pipe 22.

[0070] In this embodiment 7, both the electric heating box 2 and the heat transfer roller 3 are made of thermally conductive materials. Within the carbonization mechanism, all other structures besides the electric heating box 2 and the heat transfer roller 3 are made of heat-insulating materials. When the electric heating box generates heat to pyrolyze the medicinal herb residue inside the heat transfer roller 3, the air valve 2 on the inlet pipe 22 and the outlet pipe 23 is closed to prevent external gas from entering the insulation chamber 21 or gas leakage from the insulation chamber 21. This prevents heat loss from the box.

[0071] When the production of charcoal from Chinese medicinal herb residue is completed, the air valve 2 on the air inlet pipe 22 and the air outlet pipe 23 is opened. Air is drawn in by the fan 43 and circulated in the heat insulation chamber 21 through the air inlet pipe 22 and the air outlet pipe 23, thus allowing the interior of the chamber 1 to cool down naturally.

[0072] Example 8

[0073] like Figure 1-10 As shown, the present invention provides a biochar production system for Chinese medicinal herb residues, including a pretreatment mechanism from an external source of Chinese medicinal herb residues, a carbonization mechanism from the pretreatment mechanism, and a collection mechanism and a recycling mechanism from the carbonization mechanism respectively.

[0075] In this embodiment 8, the feed hopper 16 is provided with a movable through hole 28 and an insert slot 29 adapted to the baffle 17. The baffle 17 is sealed and inserted into the movable through hole 28. When the linear motor 18 drives the baffle 17 to extend, the baffle 17 moves along the direction from the movable through hole 28 to the insert slot 29 until the end of the baffle 17 is sealed and inserted into the insert slot 29. At this time, the baffle 17 seals and closes the feed hopper 16. When the linear motor 18 drives the baffle 17 to retract, the baffle 17 moves along the direction from the insert slot 29 to the movable through hole 28 until the end of the baffle 17 moves from the insert slot 29 to the movable through hole 28. At this time, the baffle 17 releases the seal on the movable through hole 28, so that the channel inside the feed hopper 16 is open, and new Chinese medicinal material residue can be added into the box 1 through the open channel inside the feed hopper 16.

The cooling storage box 33 is provided with an inlet pipe 37 and an outlet pipe 38 that are respectively connected to the cooling chamber 35. The inlet pipe 37 and the outlet pipe 38 are respectively connected to an external circulating cooling water source.

[0079] In this embodiment 9, the biomass carbon generated in the electric heating box 2 first falls from the last stage heat transfer roller into the temporary storage chamber 25 for temporary storage, and then falls through the outlet 26 into the cooling storage tank 33 for cooling and storage.
