Description

Technical Field

[0001] This utility model relates to the technical field of biochar processing equipment, and in particular to an integrated biochar processing system. Background Technology

[0002] Biochar is a carbon-rich solid material produced from biomass under pyrolysis conditions. Biochar fresh from the pyrolysis furnace is extremely hot (400-600℃) and must be effectively cooled before it can be safely transported, stored, and packaged. Otherwise, it is highly susceptible to spontaneous combustion, posing a serious safety hazard and affecting product quality.

[0003] Currently, the cooling, conveying, and packaging processes in biochar production are typically independent, which has many drawbacks:

[0004] Low and uneven cooling efficiency: natural cooling takes too long; air cooling is inefficient and easily leads to uneven cooling, and local high temperature may cause reignition; direct water cooling will cause the moisture content of biochar to surge and the quality to decline.

[0005] Poor system integration: The connection between various links is not smooth, it relies on a lot of manual operation, resulting in low production efficiency, high cost, and harsh on-site environment.

[0006] Prone to malfunctions during transport: Biochar has poor flowability and is prone to blockage and leakage during transport, affecting the continuity of production.

[0007] Poor storage and packaging safety: insufficiently cooled charcoal still poses a risk of reignition in the storage silo; traditional packaging is mostly done manually and inefficiently, making it difficult to guarantee packaging quality and weight consistency.

[0008] Energy waste: The large amount of heat carried by high-temperature biochar is usually directly lost during the cooling process and cannot be effectively recovered and utilized.

[0009] Therefore, there is an urgent need for an integrated, efficient, and secure system to solve the above problems. Utility Model Content

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] The purpose of this invention is to provide an integrated biochar processing system to solve the problems existing in the prior art, effectively improve the efficiency and uniformity of biochar cooling, effectively ensure the stability during transportation, effectively improve packaging quality, recover and utilize the waste heat during the cooling process, and effectively eliminate the risk of reignition.

[0036] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] This utility model provides an integrated biochar processing system, such as Figures 1-5As shown, the system includes a cooling device, a conveying device, and a packaging device connected sequentially along the biochar processing direction. The cooling device includes a first-stage indirect cooler 1 and a second-stage indirect cooler 2 connected in series for multi-stage progressive cooling of the high-temperature biochar. The conveying device includes a sealed unloader 3 and an elevator 4. The sealed unloader 3 is sealed and connected to the outlet of the second-stage indirect cooler 2 to receive the cooled biochar, and the bottom of the elevator 4 is sealed and connected to the sealed unloader 3. The packaging device includes at least one storage silo 5 and an automatic packaging machine 6. The top of the storage silo 5 is connected and connected to the top outlet of the elevator 4, and the automatic packaging machine 6 is located below the outlet of the storage silo 5 to quantitatively package the biochar. Through the sequential connection of the cooling, conveying, and packaging devices, the biochar processing flow is made continuous and systematic. Multi-stage progressive cooling can more effectively cool the high-temperature biochar to a suitable temperature, which helps to improve cooling efficiency. The sealed conveying device can prevent outside air from entering the system, reducing the risk of reignition. The automatic baler 6 is placed below the discharge port of the storage silo 5, which facilitates quantitative baling, improves the accuracy and efficiency of baling, and enhances the overall production efficiency and product quality of biochar processing.

[0038] In a preferred embodiment, the first-stage indirect cooler 1 is a water-cooled screw conveyor. The water-cooled screw conveyor includes a first frame, a housing 11, a cooling jacket 12, a discharge screw 13, and a first drive motor. The housing 11 is mounted on the first frame. The top of the housing 11 is provided with a first feed inlet 16 and the bottom is provided with a first discharge outlet 17. The cooling jacket 12 is sleeved on the outside of the housing 11. The cooling jacket 12 is provided with a first water inlet 14 and a first water outlet 15. The first water inlet 14 and the first water outlet 15 are connected to the water-cooled heat exchange equipment. The discharge screw 13 is located above the first discharge outlet 17. The first drive motor is mounted on the first frame, and the output shaft of the first drive motor is connected to the discharge screw 13. By using a water-cooled screw conveyor as the first-stage indirect cooler 1, indirect cooling can be achieved by using the cooling jacket 12 and the water-cooled heat exchange equipment while conveying biochar. This structural design ensures that the biochar exchanges heat evenly with the coolant as it moves through the screw conveyor, avoiding problems such as localized overheating or uneven cooling. Furthermore, the screw conveyor's structure provides a certain degree of agitation during transport, which helps improve the cooling effect and ensures that the biochar is smoothly conveyed from the first inlet 16 to the first outlet 17, providing uniform material at a suitable temperature for the subsequent second-stage cooling.

[0039] In a preferred embodiment, the cooling jacket 12 is provided with a plurality of reinforcing ribs 121, and the two ends of each reinforcing rib 121 are fixedly connected to the inner wall of the cooling jacket 12 and the outer wall of the housing 11, respectively. The reinforcing ribs 121 can enhance the structural strength of the cooling jacket 12 and prevent it from deforming due to internal and external pressure differences or temperature changes during long-term use.

[0040] In a preferred embodiment, the discharge screw 13 includes a rotating shaft, a first spiral blade, a second spiral blade, and a slag-removing bar 19. The rotating shaft is rotatably connected to the housing 11, and one end of the rotating shaft extending out of the housing 11 is fixedly connected to the output shaft of the first drive motor. The slag-removing bar 19 is fixedly connected to the middle of the rotating shaft and located above the first discharge port 17. The first spiral blade and the second spiral blade are sleeved and fixed on the rotating shaft and located on both sides of the slag-removing bar 19. The first spiral blade and the second spiral blade rotate in opposite directions to transport the biomass char in the housing 11 to the first discharge port 17. This design allows the spiral blades rotating in opposite directions on both sides to push the biomass char on both sides of the housing 11 towards the slag-removing bar 19 in the middle when the rotating shaft is driven by the first drive motor. This allows the biomass char to converge towards the middle during the transportation process, making it easier for the slag-removing bar 19 to break it up. This effectively prevents the biomass char from clumping and blocking at the discharge port, ensuring that the biomass char can be smoothly discharged from the first discharge port 17, further improving the operational stability and cooling efficiency of the first-stage indirect cooler 1.

[0041] In a preferred embodiment, the second-stage indirect cooler 2 is a drum 22 type cooler, which includes a base 21, a drum 22, a second drive motor 23, cooling pipes 24, and a rotary joint 25. The base 21 is installed on the working ground, and the drum 22 is installed on the base 21 and rotatably connected to it. One end of the drum 22 is provided with a second inlet 28, and the other end is provided with a second outlet 29. The second inlet 28 is connected and communicates with the first outlet 17, and the second outlet 29 is connected and communicates with the sealing unloader 3. The second drive motor 23 is installed on the base 21, and the output shaft of the second drive motor 23 is connected to the drum 22 via a transmission chain to drive the drum 22 to rotate. The cooling system 24 includes multiple sets of coils, a rotary joint 25, and connecting pipes. Each coil is installed inside the drum 22 along its axial direction. One end of the connecting pipe is connected to the coils via the rotary joint 25 to form a circulation pipeline. A second inlet 26 and a second outlet 27 are located at the end of the connecting pipe furthest from the rotary joint 25. These inlets and outlets are connected to a water-cooled heat exchange device. The drum 22-type cooler is driven by a second drive motor 23, causing the biomass char inside the drum 22 to continuously tumble and move as the drum 22 rotates. During this process, the biomass char fully contacts the multiple sets of coils inside the drum 22, utilizing the circulating cooling water for efficient heat exchange. The rotary joint 25 ensures that the cooling pipeline 24 can stably connect to the external water-cooled heat exchange device while the drum 22 is rotating, achieving continuous supply and circulation of cooling water, further improving the cooling effect, and further reducing the temperature of the biomass char after the second stage of cooling to meet the stringent temperature requirements of subsequent processing.

[0042] In a preferred embodiment, an inspection port 18 is provided on the connecting pipe between the first discharge port 17 and the second inlet port 28. The inspection port 18 facilitates the operator to inspect, clean blockages, or replace parts inside the connecting pipe during system operation or periodic maintenance, effectively preventing the normal transportation of biochar from being affected by pipe blockage or damage, and improving the system's maintenance convenience and operational reliability.

[0043] In a preferred embodiment, the sealed unloader 3 is a star-shaped unloader with a third inlet and a third outlet. The third inlet is sealed and connected to the second outlet 29, and the third outlet is connected and connected to the bottom of the elevator 4. The star-shaped unloader continuously and evenly unloads the biomass char delivered from the second outlet 29 into the bottom of the elevator 4 through its internal rotating impeller. At the same time, the tight fit between the impeller and the shell 11 achieves a good sealing effect, which can effectively prevent the biomass char from leaking and polluting the environment during the unloading process, and also prevent outside air from entering the system through the unloading port and coming into contact with the high-temperature biomass char, further reducing the risk of reignition and ensuring the safety and stability of the biomass char transportation process.

[0044] In a preferred embodiment, the elevator 4 is a sealed bucket elevator 4, which includes a second frame, a head, a tail, a traction component, buckets, and a third drive motor. The head and tail are respectively installed on the top and bottom of the second frame. The tail is sealed and connected to the third discharge port, and the head is connected to the top of the storage silo 5. The traction component is wound between the head and tail, and the buckets are evenly fixed on the traction component. The third drive motor is installed at the head and is connected to the traction component for transmission. The third drive motor drives the traction component to operate, causing the buckets to scoop up biomass char from the bottom of the tail and lift it to the head. The biomass char is then unloaded into the storage silo 5 by the unloading mechanism at the head. The sealed design ensures that there is no dust leakage during the lifting process and prevents outside air from entering. Combined with the continuous conveying of the buckets, it realizes efficient and sealed transfer of biomass char from a low position to a high position in the storage silo 5, further ensuring the safety and environmental protection of the system operation.

[0045] In a preferred embodiment, the system further includes a nitrogen source 7, a pressure sensor 71, and a control valve 72. The storage silo 5 is a sealed silo. The top of the storage silo 5 is provided with a fourth inlet and a feed valve, and the bottom is provided with a fourth outlet 53 and a discharge valve. The fourth inlet and the third outlet are sealed and connected. The feed valve is located at the fourth inlet. The fourth outlet 53 is connected and connected to the automatic baler 6. The discharge valve is located at the fourth outlet 53. The nitrogen source 7 is connected and connected to the storage silo 5 through a nitrogen pipeline. The control valve 72 is located on the nitrogen pipeline. The pressure sensor 71 is located inside the storage silo 5. The pressure sensor 71 monitors the pressure inside the storage silo 5 in real time. When the pressure inside the storage silo 5 is lower than the set value, the control valve 72 automatically opens, and the nitrogen source 7 fills the storage silo 5 with nitrogen, maintaining a slightly positive pressure inside the storage silo 5 to further isolate oxygen and effectively prevent the biochar from reigniting inside the storage silo 5. When the pressure reaches the set value, the control valve 72 automatically closes to save nitrogen consumption.

[0046] In a preferred embodiment, there are two storage bins 5. The third discharge port is selectively connected to the fourth feed port of the two storage bins 5 via a distributor 52. The distributor 52 can control the material flow direction through electric or pneumatic valves, and achieves automated switching in conjunction with the material level sensor in the storage bin 5, ensuring that the biomass char continuously and stably enters the baling stage. One char bin is the main char bin, whose main function is to store the finished char; the other is a backup char bin. One function is to switch to the backup char bin for re-carbonization when the biomass char does not meet the quality standards, and the other function is to temporarily store the biomass char when the main char bin is full due to baling machine failure or maintenance. The char bin is designed to have a storage capacity of 12 hours, which ensures that baling work is only carried out during the day shift, saving labor costs.

[0047] In a preferred embodiment, the storage silo 5 is equipped with a leveler 51, which includes a fourth drive motor, a transmission shaft, and multiple stirring blades. The transmission shaft is vertically installed inside the storage silo 5 and rotatably connected to the top of the storage silo 5. The fourth drive motor is installed on the outer side of the top of the storage silo 5, and its output shaft is fixedly connected to the top of the transmission shaft. The multiple stirring blades are spaced apart along the axial direction of the transmission shaft and fixedly connected to the transmission shaft. The length direction of the stirring blades is consistent with the radial direction of the transmission shaft, so as to stir the biomass char in the storage silo 5 when the transmission shaft rotates, preventing the material from accumulating and arching. In actual operation, when local accumulation of biomass char occurs in the storage silo 5, the leveler 51 can disperse and level the material by rotating the stirring blades, ensuring that the material can be evenly distributed and smoothly discharged from the fourth discharge port 53, avoiding interruption of packaging due to material blockage, and further improving the stability and continuity of system operation.

[0048] In a preferred embodiment, the automatic baling machine 6 includes a weighing unit 61, a clamping unit for gripping and opening the packaging bag, and a vibration unit for compacting the material inside the bag. The clamping unit includes a suction cup 62, a gripper 63, a fixing clamp 64, and a sealing clamp 65. The vibration unit is a vibrator 67. The working process is as follows: the suction cup 62 first grips a single bag; the gripper 63 grabs the bag from the opening and places it into the fixing clamp 64; the fixing clamp 64 clamps both sides of the bag, opening it. Biomass char falls from the top outlet through the weighing unit 61 into the baling bag 66. At this time, the vibrator 67 is activated, and the vibration makes the biomass char in the bag more compact. After vibration, filling continues until the bag is filled with the designed weight of biomass char. This baling machine is designed with a vibration unit specifically for the characteristics of biomass char. The design of vibrating while filling effectively solves the problem of wasted baling bags 66 caused by the inability to fill the bags completely with biomass char in traditional automatic baling machines 6, improving production efficiency and saving production costs.
