Description

Technical Field

[0001] This invention relates to a carbon material preparation apparatus, specifically a porous carbon continuous activation apparatus. Background Technology

[0002] The industrial production of porous carbon materials mainly relies on physical activation processes, which involve introducing water vapor, carbon dioxide, or a mixture thereof as activation media at high temperatures to selectively etch carbon precursors, thereby constructing complex porous structures.

[0003] In existing continuous production processes, the activation reaction stage generates a large amount of high-temperature flue gas, which is extremely hot and carries significant heat energy. To improve energy efficiency and reduce energy consumption, effective heat recovery from this high-temperature flue gas is usually required. However, during the flow of the high-temperature flue gas from its source to the recovery device, heat loss occurs continuously due to factors such as pipeline heat dissipation, ambient temperature differences, and unavoidable heat exchange, resulting in the loss of some usable heat energy. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a porous carbon continuous activation device, which solves the problem of wasted heat energy in the activation reaction stage of existing continuous production processes.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a porous carbon continuous activation device, comprising a support frame, two combustion chambers at the bottom of the support frame, a reactor tube rotatably connected to the inner wall of the support frame, toothed rings fixedly connected to both sides of the reactor tube, a fixed frame fixedly connected to one end of the support frame, a motor I mounted on the top of the fixed frame, a transmission rod fixedly connected to the output end of the motor I, gears mounted on both sides of the transmission rod, a spiral lifter slidably connected to the inner wall of the combustion chamber, a fixing element provided at one end of the spiral lifter, a conveying pipe slidably connected to the inner wall of the spiral lifter, a movable frame mounted at one end of the conveying pipe, a motor II mounted at one end of the movable frame, an auger fixedly connected to the output end of the motor II, a feed hopper mounted at one end of the conveying pipe, and a discharge device mounted at the other end of the support frame.

[0006] By adopting the above technical solution: a motor drives the auger to rotate, propelling the raw material forward. The raw material is gradually conveyed to the other end within the conveying pipe, continuously heated during this process. When the raw material reaches the outlet of the conveying pipe, it enters the inner wall area of ​​the reactor tube. Inside the reactor tube, a spiral lifter lifts the raw material, a process that helps the reactor tube reheat the raw material, thereby accelerating its conversion into porous carbon. Simultaneously, the porous carbon gradually moves to the other end of the reactor tube until it contacts the inner wall of the other end of the support. Subsequently, the porous carbon is discharged from the device through the discharge device at the bottom of the support. This achieves the effect of improving thermal energy utilization.

[0007] Preferably, both the fixing frame and the conveying pipe have fixing holes at one end, so that a fixing member is slidably connected to the inner wall of the fixing hole.

[0008] Preferably, a feeding mechanism is provided at the top of the feed hopper, and the auger frame is rotatably connected to the inner wall of the conveying pipe.

[0009] Preferably, the inner wall of the combustion chamber is provided with a combustion device to heat the reactor tube.

[0010] Preferably, the spiral lifter is rotatably connected to the outer wall of the conveying pipe, and the other end of the spiral lifter is rotatably connected to the outer wall of the other end of the support.

[0011] Preferably, a fixing block is provided at the other end of the fixing frame, and it contacts the hole at the other end of the conveying pipe, and the other end of the conveying pipe is slidably connected to the outer wall of the fixing frame.

[0012] Preferably, the transmission rod is rotatably connected to the top of the bracket, and the gear is meshed with the tooth end of the gear ring.

[0013] Preferably, multiple pulleys are rotatably connected to the inner walls of both sides of the support, and the multiple pulleys are rotatably connected to the outer wall of the reactor tube.

[0014] Preferably, the outer wall of the spiral lifter is provided with multiple spiral lifter plates, which are slidably connected to the inner wall of the reactor tube.

[0015] Preferably, the discharge device includes a motor and an auger blade. The auger blade is installed at the output end of the motor and rotatably connected to the inner wall of the discharge device. The motor is installed inside the discharge device.

[0016] This invention provides a continuous activation device for porous carbon. It has the following beneficial effects: 1. This invention drives the auger frame to rotate by starting motor 2, which pushes the raw material through the conveying pipe and heats it. The raw material enters the reactor tube, and the spiral lifter lifts the material and heats it again to make porous carbon. The porous carbon moves to the other end of the reactor tube and is removed by the discharge device at the bottom of the support, thereby improving the thermal energy utilization rate.

[0017] 2. The conveying pipe of the present invention is fixed by a fixed frame to prevent the moving frame from moving the conveying pipe; the fixed block contacts the hole on the conveying pipe so that the conveying pipe remains fixed when the reactor tube drives the spiral lifting frame to rotate, which effectively avoids uneven material conveying or equipment wear caused by the shaking of the conveying pipe, while ensuring the stability of the internal thermal field of the reactor tube and improving the continuity and uniformity of the activation process.

[0018] 3. The present invention pulls out the fixing component from the fixing frame and the outer wall of the conveying pipe, and pushes the moving frame to drive the spiral lifting frame to move outward, which facilitates the cleaning of residual materials and carbon deposits inside the device, avoids blockage or heat conduction efficiency reduction caused by long-term operation, and at the same time reduces maintenance difficulty and improves the stability and safety of continuous operation of the equipment.

[0021] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see the appendix Figure 1 -Appendix Figure 8 This invention provides a porous carbon continuous activation device, comprising a support 1, with two combustion chambers 2 at the bottom of the support 1. A reactor tube 3 is rotatably connected to the inner wall of the support 1, and gear rings 4 are fixedly connected to both sides of the reactor tube 3. A fixing frame 5 is fixedly connected to one end of the support 1, and a motor 6 is installed at the top of the fixing frame 5. A transmission rod 7 is fixedly connected to the output end of the motor 6, and gears 8 are installed on both sides of the transmission rod 7. A spiral lifter 17 is slidably connected to the inner wall of the combustion chambers 2, and a fixing member 15 is provided at one end of the spiral lifter 17. A conveying pipe 10 is slidably connected to the inner wall of the spiral lifter 17, and a movable frame 9 is installed at one end of the conveying pipe 10. A second motor 11 is installed at one end of the movable frame 9, and an auger frame 12 is fixedly connected to the output end of the second motor 11. A feed hopper 13 is installed at one end of the conveying pipe 10, and a discharge device is installed at the other end of the support 1. The device 14 has a feeding mechanism at the top of the feed hopper 13, an auger frame 12 rotatably connected to the inner wall of the conveying pipe 10, a combustion device on the inner wall of the combustion chamber 2 to heat the reactor tube 3, a spiral lifter 17 rotatably connected to the outer wall of the conveying pipe 10, the other end of the spiral lifter 17 rotatably connected to the outer wall of the other end of the support 1, a transmission rod 7 rotatably connected to the top of the support 1, a gear 8 meshing with the tooth end of the gear ring 4, multiple pulleys 16 rotatably connected to the inner walls of both sides of the support 1, multiple pulleys 16 rotatably connected to the outer wall of the reactor tube 3, multiple spiral lifter plates on the outer wall of the spiral lifter 17 and slidably connected to the inner wall of the reactor tube 3, and a discharge device 14 including a motor and an auger blade. The auger blade is installed at the output end of the motor and rotatably connected to the inner wall of the discharge device 14, and the motor is installed inside the discharge device 14.

[0023] Specifically, motor 6 is started, causing it to drive two gears 8 to rotate via transmission rod 7. These gears 8, through gear ring 4, drive the reactor tube 3 to rotate within the support 1, ensuring the combustion device in combustion chamber 2 uniformly heats the outer wall of the reactor tube 3. When the internal temperature of the reactor tube 3 reaches a suitable level, the feeding mechanism at the top of feed hopper 13 feeds the dried raw material into conveying pipe 10. Then, motor 11 is started, causing it to drive the auger frame 12 to rotate, which in turn moves the raw material. The material is moved to the other end of the conveying pipe 10. During the movement of the material, the material is heated and enters the inner wall of the reactor tube 3 from the outlet of the conveying pipe 10. When the reactor tube 3 passes the spiral lifter 17 to lift the material, it is convenient for the reactor tube 3 to reheat the material and make the material into porous carbon. During the lifting process, the porous carbon moves to the other end of the reactor tube 3 and contacts the inner wall of the other end of the support 1. The porous carbon is then removed from the device through the discharge device 14 at the bottom of the support 1, thereby improving the thermal energy utilization rate.

[0024] Please see the appendix Figure 2 Appendix Figure 4 and attached Figure 7 The fixing frame 5 and the conveying pipe 10 are both provided with fixing holes at one end, so that the inner wall of the fixing hole is slidably connected to the fixing member 15. The other end of the fixing frame 5 is provided with a fixing block, which contacts the hole at the other end of the conveying pipe 10. The other end of the conveying pipe 10 is slidably connected to the outer wall of the fixing frame 5.

[0025] Specifically, by using the fixing hole 1501 through the conveying pipe 10 and the fixing frame 5, the conveying pipe 10 is fixed on the fixing frame 5, which can prevent the moving frame 9 from moving the conveying pipe 10. At the same time, the fixing block on the fixing frame 5 contacts the hole on the conveying pipe 10, so that the conveying pipe 10 can remain fixed when the reactor tube 3 drives the spiral scraper 17 to rotate. The fixing part 15 is pulled out to separate it from the outer wall of the fixing frame 5 and the conveying pipe 10, so that the staff can push the moving frame 9 to move the spiral scraper 17 outward, thereby achieving the effect of facilitating the cleaning of the inside of the device.

[0026] Working Principle: Motor 6 is started, driving transmission rod 7 to rotate. Transmission rod 7 drives two gears 8 to rotate synchronously. Gears 8 mesh with gear ring 4, indirectly driving the reactor tube 3 to rotate within the inner wall of support 1. During this process, the combustion device in combustion chamber 2 continuously heats the outer wall of reactor tube 3. When the internal temperature of reactor tube 3 gradually rises and reaches a preset suitable temperature, the feeding mechanism at the top of feed hopper 13 is activated, introducing pre-dried raw materials into conveying pipe 10 through feed hopper 13. Subsequently, motor 11 is started, driving auger 12 to rotate. The spiral blades of auger 12 push the raw materials forward along conveying pipe 10. During the process of conveying raw materials from one end of conveying pipe 10 to the other, the raw materials continuously receive heating from the surrounding heat source, causing their temperature to gradually rise. When the raw materials move to the outlet at the other end of conveying pipe 10, they enter the inner wall of reactor tube 3. The reactor tube 3 uses a built-in spiral lifter 17 to agitate and lift the raw materials, ensuring uniform mixing. The reactor tube 3 then reheats the raw materials, accelerating their transformation into porous carbon material at high temperatures. During the continuous lifting process of the spiral lifter 17, the resulting porous carbon gradually moves towards the other end of the reactor tube 3, eventually contacting the inner wall of the other end of the support 1. The porous carbon is discharged from the device through the discharge device 14 at the bottom of the support 1, improving the overall system's thermal efficiency. A fixing element 1501, passing through corresponding fixing holes on the conveying pipe 10 and the fixed frame 5, secures the conveying pipe 10 to the fixed frame 5, effectively preventing unnecessary displacement of the conveying pipe 10 during the movement of the moving frame 9. Simultaneously, the fixing block on the fixed frame 5 engages with the positioning hole on the conveying pipe 10, ensuring that the conveying pipe 10 remains stable and stationary while the reactor tube 3 rotates the spiral lifter 17, thus guaranteeing operational reliability. When it is necessary to clean the inside of the device, the staff can first pull out the fixing part 15, so that it is completely separated from the outer wall of the fixing frame 5 and the conveying pipe 10. Then, by manually pushing the moving frame 9, it will drive the spiral lifter 17 to move outward as a whole, thereby pulling the spiral lifter 17 out of the reactor tube 3, so as to facilitate the cleaning and maintenance of the inside of the device and ensure the long-term stable operation of the equipment.
