Description

Technical Field

[0001] This application relates to the field of carbon material preparation technology, and in particular to a carbon material activation treatment device. Background Technology

[0002] With the development of carbon material preparation technology, a method has emerged that utilizes activation processes to regulate the pore structure of carbon materials. This method involves placing the carbon material to be activated and an activating agent together in a high-temperature environment. Through the reaction between the activating agent and carbon atoms, a well-developed pore structure is formed within the carbon material, thereby obtaining activated carbon products with adsorption capabilities. However, single-chamber activation furnaces are prone to producing thick material layers and severe accumulation during material processing, leading to uneven temperature distribution within the material layer and insufficient contact between the activating agent and the carbon material, thus affecting the activation effect and product quality.

[0003] In related technologies, a rotatable rotary activation furnace is used as the activation treatment equipment for carbon materials. This type of equipment typically loads the carbon material to be activated directly into the furnace chamber. The rotation of the furnace body causes the material to tumble, while high-temperature steam or carbon dioxide is introduced into the furnace chamber as an activating agent, causing the carbon material to react with the activating agent at high temperature.

[0004] However, the above processing method has the following problems: when the furnace rotates, the material in the furnace chamber tends to rotate synchronously with the furnace, and the material layer lacks effective turning and mixing, resulting in insufficient contact between the carbon material and the activator inside the material layer, uneven temperature distribution inside and outside the material layer, which ultimately affects the activation effect and product quality. Summary of the Invention

[0005] This application provides a carbon material activation treatment device to solve the problems in the prior art where, when a rotary activation furnace processes carbon materials, the material inside the furnace chamber tends to rotate synchronously with the furnace body, resulting in a lack of effective turning and mixing inside the material layer, insufficient contact between the carbon material and the activator, and uneven temperature distribution.

[0006] This application provides a carbon material activation treatment device, comprising: a main cylinder, rotatably disposed; at least one fixed disk, coaxially fixed inside the main cylinder, the fixed disk having a plurality of first mounting holes evenly disposed along the circumference; activation cylinders, a plurality of activation cylinders corresponding to the first mounting holes, each activation cylinder being fixedly inserted through a corresponding first mounting hole along the axial direction of the main cylinder, the activation cylinder being used to contain carbon material to be activated and an activator; and a turning frame, rotatably disposed inside each activation cylinder, the turning frame including a rotating frame and a turning plate, a shovel, and an eccentric counterweight disposed on the rotating frame, the side of the shovel away from the rotating frame contacting and engaging with the inner wall of the activation cylinder, the center of gravity of the eccentric counterweight being offset from the central axis of the activation cylinder, the eccentric counterweight being configured to drive the turning frame to rotate relative to the activation cylinder when the main cylinder rotates.

[0009] According to one embodiment of this application, multiple fixed disks are provided, and the multiple fixed disks are spaced apart along the axial direction of the main cylinder. The multiple fixed disks sequentially divide the inner cavity of the main cylinder into a preheating zone, a carbonization zone, an activation zone and a cooling zone along the axial direction.

[0010] According to one embodiment of this application, a gas supply heating system is further included, comprising: a steam generator having a first outlet for outputting steam and a second outlet for outputting flue gas, the first outlet being connected to a plurality of activation cylinders; a gas heating unit located inside the main cylinder, the gas heating unit comprising a distribution plate, heating pipes, and a manifold plate, the distribution plate being adjacent to a fixed plate located between the activation zone and the cooling zone, the manifold plate being located in the preheating zone, the distribution plate having a distribution channel connected to the second outlet, the manifold plate having a manifold channel connected to the exhaust pipe, a plurality of heating pipes being disposed between the plurality of activation cylinders and passing through a second mounting hole of the fixed plate, the heating pipes being connected to the distribution channel and the manifold channel; and auxiliary electric heating elements being disposed in the preheating zone, the carbonization zone, and the activation zone, for supplementing heating when the heat of the flue gas is insufficient.

[0011] According to one embodiment of this application, a composite drive system is also included, comprising: an inclination adjustment mechanism connected to the main cylinder for adjusting the inclination angle of the axis of the main cylinder relative to the horizontal plane; a rotation drive mechanism connected to the main cylinder for driving the main cylinder to rotate axially; and a control unit electrically connected to the inclination adjustment mechanism and the rotation drive mechanism respectively for controlling the inclination angle and rotation speed of the main cylinder.

[0012] According to one embodiment of this application, the tilt adjustment mechanism includes: a tilt sensor disposed on the main cylinder and signal-connected to the control unit for detecting the tilt angle of the main cylinder; a first support ring rotatably sleeved on the outer side of the middle portion of the main cylinder and forming an axial limit with the main cylinder; a base fixedly disposed on the mounting base surface and hinged to the first support ring; at least two second support rings disposed on both sides of the first support ring along the axial direction of the main cylinder and slidably sleeved on the outer side of the main cylinder; and at least two lifting drive components, each vertically mounted on the mounting base surface and hinged to each of the second support rings in a one-to-one correspondence, wherein the lifting drive components are electrically connected to the control unit and are used to perform lifting actions according to the instructions of the control unit.

[0013] According to one embodiment of this application, the rotary drive mechanism includes: a drive motor, fixedly connected to the first support ring and electrically connected to the control unit; a driven gear, coaxially fixed to the outside of the main cylinder; and a drive gear, coaxially fixed to the outside of the motor shaft of the drive motor and meshing with the driven gear.

[0014] According to one embodiment of this application, it further includes: a cleaning medium generator for generating a cleaning medium; a material supply system for supplying the carbon material to be activated; a distributor fixed inside the main cylinder, the distributor having multiple dispensing holes respectively communicating with multiple activation cylinders; a feed end cap rotatably connected to the front end of the main cylinder, the feed end cap, the main cylinder, and the distributor forming a dispensing chamber communicating with the dispensing holes, the feed end cap having a first inlet communicating with the cleaning medium generator and a second inlet communicating with the material supply system; a discharge end cap rotatably connected to the end of the main cylinder, the discharge end cap having a discharge port and a drain port; and a control valve group communicating with the first inlet, the second inlet, the discharge port, and the drain port, for controlling the opening and closing of the first inlet, the second inlet, the discharge port, and the drain port.

[0015] According to one embodiment of this application, a shearing member is fixedly installed at the end of the main cylinder. The shearing member is arranged perpendicular to the axial direction of the main cylinder and is used to shear the material discharged from the end of the main cylinder.

[0016] The carbon material activation treatment device provided in this application, by setting at least one fixed plate inside the main cylinder and inserting multiple activation cylinders axially through the first mounting hole of the fixed plate, disperses the carbon material to be activated and the activator into multiple parallel-arranged activation cylinders, significantly reducing the material layer thickness in a single treatment and structurally avoiding internal heating dead zones caused by excessive material accumulation. Simultaneously, each activation cylinder is independently equipped with a rotatable tilting frame, which includes a tilting plate, a scraper, and an eccentric counterweight. When the main cylinder rotates, the eccentric counterweight, under the combined action of centrifugal force and gravity difference, drives the tilting frame to rotate at a differential speed with the activation cylinder. This differential rotation, on the one hand, causes the tilting plate to stir the material, forcing the material to tumble and mix inside the activation cylinder, effectively breaking the state of synchronous rotation of the material with the furnace body, allowing the carbon material particles to come into more full contact with the activator; on the other hand, this differential rotation drives the scraper to move against the inner wall of the activation cylinder, promptly scraping off the material adhering to the cylinder wall, preventing local material accumulation and heat transfer obstruction. With the above structure, this application helps the material to turn and mix in the activation cylinder, preventing the material from rotating synchronously with the furnace body, thereby effectively improving the contact efficiency between carbon materials and activators.

[0042] The following is combined Figures 1-3 This application describes a carbon material activation treatment apparatus according to an embodiment of the present application.

[0043] In one embodiment, the carbon material activation treatment device includes a main cylinder 100, at least one fixed plate 200, a plurality of activation cylinders 300, and a material turning rack 400.

[0044] The main cylinder 100 is rotatably mounted. The main cylinder 100 has a cylindrical structure, with an inlet and an outlet at its two ends, respectively. The inner wall of the main cylinder 100 is smooth. The main cylinder 100 can rotate around its own axis under the drive of an external drive structure.

[0045] The fixed disk 200 has a disc-shaped structure, and its outer diameter is adapted to the inner diameter of the main cylinder 100. The fixed disk 200 is coaxially fixed inside the main cylinder 100, for example, by welding, bolting, or keying. Multiple first mounting holes 210 are evenly arranged circumferentially on the fixed disk 200, and these first mounting holes 210 penetrate the thickness direction of the fixed disk 200. The number and diameter of the first mounting holes 210 are determined according to the actual production scale, for example, four to twenty-four. The central axis of the first mounting holes 210 is parallel to the central axis of the main cylinder 100. There can be one or more fixed disks 200. When multiple fixed disks 200 are provided, they are arranged at intervals along the axial direction of the main cylinder 100, jointly supporting and positioning the activation cylinder 300.

[0046] The activation cylinder 300 is a slender cylindrical structure, with its outer diameter matching or slightly smaller than the inner diameter of the first mounting hole 210. The number of activation cylinders 300 is equal to the number of first mounting holes 210. Each activation cylinder 300 passes through the corresponding first mounting hole 210 along the axial direction of the main cylinder 100, and is relatively fixed to the main cylinder 100. After passing through the fixing plate 200, the activation cylinder 300 extends to positions close to both ends of the main cylinder 100. The inner cavity of the activation cylinder 300 is used to accommodate the carbon material to be activated and the activating agent.

[0047] Multiple activation cylinders 300 are evenly distributed circumferentially along the main cylinder 100. This parallel arrangement disperses the material to be treated (the carbon material to be activated and the activating agent) into each activation cylinder 300, significantly reducing the material layer thickness within each activation cylinder 300. With a reduced material layer thickness, heat is more easily transferred from the walls of the activation cylinder 300 to the center of the material, avoiding the problem of insufficient internal heating caused by an excessively thick material layer in a single large-capacity reactor. Simultaneously, due to the smaller diameter of the activation cylinders 300, the activating agent gas can penetrate the entire material layer more quickly, resulting in more thorough contact between the material and the activating agent.

[0048] A tilting frame 400 is rotatably disposed inside each activation cylinder 300. The tilting frame 400 includes a rotating frame 410, tilting plates 420, a scraper 430, and an eccentric counterweight 440. The rotating frame 410 can be a plate-like or rod-like structure arranged radially along the activation cylinder 300. When the rotating frame 410 is a plate-like structure, it extends axially along the activation cylinder 300, and the rotating frame 410 can rotate circumferentially within the activation cylinder 300. The tilting plates 420 are fixedly disposed on the rotating frame 410, located on both sides of the rotating frame 410, and positioned off-center from the centerline of the activation cylinder 300. One side of the tilting plate 420 is fixedly connected to the rotating frame 410, and the other side extends away from the rotating frame 410. Multiple tilting plates 420 can be provided, and they are symmetrical about the centerline of the activation cylinder 300 in pairs. The tilting plate 420 can be a straight plate or an arc-shaped plate. For example, the tilting plate 420 can be an arc-shaped plate, and the bending center of the tilting plate 420 coincides with the center line of the activation cylinder 300. The scraper 430 is fixedly installed near both ends of the rotating frame 410. The scraper 430 can also be a plate-shaped structure, with one side fixedly connected to the rotating frame 410 and the other side contacting and engaging with the inner wall of the activation cylinder 300. The blade shape of the scraper 430 can be set to match the curvature of the inner wall of the activation cylinder 300 to ensure tight contact. Multiple scrapers 430 can be provided, preferably one at each end of the rotating frame 410. An eccentric counterweight 440 is fixedly mounted on the rotating frame 410. The center of gravity of the eccentric counterweight 440 is offset from the central axis of the rotating frame 410. The eccentric counterweight 440 is configured to drive the tilting frame 400 to rotate relative to the activation cylinder 300 when the main cylinder 100 rotates. In other words, the eccentric counterweight 440 causes the tilting frame 400 and the activation cylinder 300 to rotate at a different speed when the main cylinder 100 rotates. The shape of the eccentric counterweight 440 can be fan-shaped, circular, or irregular, and its mass is determined according to the required differential speed of the tilting frame 400.

[0049] When the main cylinder 100 rotates, it drives the fixed disk 200 to rotate, which in turn drives all the activation cylinders 300 mounted on it to revolve synchronously. Simultaneously, the tilting frame 400 within each activation cylinder 300 revolves with it. During this revolution, the eccentric counterweight 440 on the tilting frame 400 is subjected to both centrifugal force and gravity. Because the center of gravity of the eccentric counterweight 440 is offset from the center of rotation, the centrifugal force generates a torque relative to the center of rotation. This torque drives the tilting frame 400 to produce additional rotational motion relative to the activation cylinders 300. When the rotational speed of the tilting frame 400 differs from that of the activation cylinders 300, differential rotation occurs. The magnitude of this differential rotation is determined by the mass and eccentricity of the eccentric counterweight 440, as well as the rotational speed of the main cylinder 100.

[0050] On the one hand, as the turning plate 420 rotates differentially with the turning frame 400, it continuously turns the material inside the activation cylinder 300. This forced turning breaks the state of the material rotating synchronously with the activation cylinder 300. The relative movement between the material particles increases the contact opportunities between the carbon material and the activator gas. The gas molecules are more likely to diffuse into the surface and internal pores of the material particles, thereby accelerating the activation reaction and making the material more evenly heated.

[0051] On the other hand, when the scraper 430 rotates at a differential speed with the tipping frame 400, the scraper 430 contacts and engages with the inner wall of the activation cylinder 300, and the movement speed of the scraper 430 differs from the rotation speed of the activation cylinder 300 wall. This scraping action causes the blade of the scraper 430 to scrape against the inner wall of the activation cylinder 300. This scraping action removes material particles adhering to the inner wall of the activation cylinder 300. During the activation process, carbon materials may soften, melt, or react with the activator at high temperatures to form sticky substances, which easily adhere to the inner wall of the activation cylinder 300. If not removed in time, the adhesion layer will gradually thicken, not only reducing the effective volume of the activation cylinder 300 but also decreasing heat transfer efficiency. The scraping action of the scraper 430 effectively prevents the formation and accumulation of the adhesion layer, maintaining the cleanliness of the inner wall of the activation cylinder 300, thereby ensuring that heat can be efficiently transferred from the activation cylinder 300 wall to the material.

[0052] On the other hand, the differential rotation generated by the eccentric counterweight 440 decouples the motion of the tilting frame 400 from that of the activation cylinder 300. Even if the rotational speed of the main cylinder 100 changes, or the filling amount and properties of the material in the activation cylinder 300 change, the tilting frame 400 can still maintain relative motion with the activation cylinder 300, thus continuously performing the tilting and cleaning functions. This adaptive characteristic allows the device to adapt to the processing needs of different types and batches of materials.

[0053] As can be seen, in this embodiment, the material is continuously and forcibly turned and mixed in the activation cylinder 300, the contact efficiency between the carbon material and the activator is significantly improved, and the temperature distribution is more uniform. This effectively solves the technical problems in the prior art, such as the lack of effective turning and mixing, insufficient contact between the carbon material and the activator, and uneven temperature distribution caused by the synchronous rotation of the material with the furnace body.

[0054] Optionally, the rotating frame 410 includes two frames, which can be either cross-shaped or straight rod-like structures. The two frames are spaced apart along the axial direction of the activation cylinder 300. Each frame is provided with an eccentric counterweight 440. The shovel 430 and the tipping plate 420 are connected between the two frames.

[0055] It should be noted that each activation cylinder 300 may contain multiple tilting frames 400 arranged along the axial direction of the activation cylinder 300, or only one tilting frame 400 may be provided. To avoid excessive relative rotational resistance between the tilting frame 400 and the activation cylinder 300, which could cause the tilting frame 400 and the activation cylinder 300 to rotate synchronously, it is preferable to provide multiple tilting frames 400, thereby shortening the axial dimension of the tilting frame 400 along the activation cylinder 300. Furthermore, it should be noted that the tilting frame 400 may simply oscillate or rotate circumferentially, as long as it rotates relative to the activation cylinder 300 under the action of the eccentric counterweight 440.

[0056] Combination Figure 4 In one embodiment, the carbon material activation treatment apparatus further includes a tensioning device 500. The tensioning device 500 is disposed between each first mounting hole 210 and the activation cylinder 300, for fixing the activation cylinder 300 within the first mounting hole 210.

[0057] In actual operation, the activation cylinder 300 is in a high-temperature environment, with temperatures reaching 800 to 1000 degrees Celsius. The activation cylinder 300 and the fixed plate 200 are made of different materials, or even if they are made of the same material, their thermal expansion rates differ due to differences in shape and size. If a rigid fixing method is used, this difference in thermal expansion will generate enormous thermal stress, causing deformation of the fixed plate 200, bending of the activation cylinder 300, or cracking at the connection points. The tensioning device 500 solves this problem.

[0058] The tensioning device 500 includes a retaining ring 510 and multiple elastic clamping components 520. The retaining ring 510 has a circular structure, and its outer diameter is adapted to the inner diameter of the first mounting hole 210. The retaining ring 510 is fixedly installed on the inner wall of the first mounting hole 210 and can be fixed by interference fit, welding or screw connection. The retaining ring 510 is made of high-temperature resistant alloy steel.

[0059] Multiple elastic clamping components 520 are disposed radially inside the retaining ring 510, and are evenly distributed circumferentially. Each elastic clamping component 520 includes a fixed section 521, a movable section 522, and an elastic support member 523. The fixed section 521 is fixedly connected to the retaining ring 510, which can be achieved by welding or integral molding. The movable section 522 is slidably connected to the fixed section 521 radially along the retaining ring 510, and one end of the movable section 522 near the center of the retaining ring 510 contacts and engages with the outer wall of the activation cylinder 300. A guide structure, such as a groove and a slide rail, is provided between the fixed section 521 and the movable section 522, or a telescopic sleeve structure is used between the fixed section 521 and the movable section 522 to ensure that the movable section 522 can slide smoothly radially without deflection. The elastic support member 523 connects the fixed section 521 and the movable section 522, and provides elastic force to the movable section 522 toward the activation cylinder 300. The elastic support 523 can be a coil spring, disc spring, etc., and its elastic force is determined by calculation. It must ensure sufficient clamping force to prevent the activation cylinder 300 from loosening, and also ensure that it can be compressed during thermal expansion. For example, the fixed section 521 is sleeved on the outside of the movable section 522, and the elastic support 523 is disposed on the inside of the fixed section 521 and abuts against the end of the movable section 522 away from the activation cylinder 300. When the movable section 522 slides toward the fixed section 521, the elastic support 523 is compressed and deformed.

[0060] When the activation cylinder 300 is inserted into the first mounting hole 210, the movable section 522, under the action of the elastic support 523, presses against the outer wall of the activation cylinder 300, clamping and fixing the activation cylinder 300. When the temperature rises, the radial dimension of the activation cylinder 300 increases, and the movable section 522 moves outward against the elastic force of the elastic support 523 to accommodate the expansion of the activation cylinder 300; when the temperature decreases, the radial dimension of the activation cylinder 300 decreases, and the movable section 522 moves inward under the action of the elastic force of the elastic support 523, always maintaining contact with the outer wall of the activation cylinder 300. In this way, the tensioning device 500 not only achieves reliable fixing of the activation cylinder 300, but also achieves thermal expansion compensation, avoiding thermal stress damage.

[0061] In addition, the tensioning device 500 can fix the fixed plate 200 and the activation cylinder 300, which can also reduce the difficulty of disassembling and assembling the activation cylinder 300. When there is blockage or material accumulation inside the activation cylinder 300, it is easy to disassemble and clean it. Or, when the material turning rack 400 is jammed or severely worn, it is easy to remove the activation cylinder 300 for cleaning.

[0062] Optionally, each first mounting hole 210 is provided with a plurality of tensioning devices 500. The plurality of tensioning devices 500 are evenly arranged around the circumference of the first mounting hole 210 and all face the center of the first mounting hole 210. The plurality of tensioning devices 500 are elastically abutted against the activation cylinder 300.

[0063] In one embodiment, multiple fixed disks 200 are provided. The multiple fixed disks 200 are spaced apart along the axial direction of the main cylinder 100, and the multiple fixed disks 200 sequentially divide the inner cavity of the main cylinder 100 into a preheating zone 110, a carbonization zone 120, an activation zone 130 and a cooling zone 140 along the axial direction.

[0064] For example, the first mounting holes 210 of the multiple fixed plates 200 are aligned along the axial direction of the main cylinder 100, so that the activation cylinder 300 can be simultaneously inserted into the first mounting holes 210 of the multiple fixed plates 200. The fixed plates 200 can be provided in four or five as needed, thereby dividing the main cylinder 100 into four areas: a preheating zone 110, a carbonization zone 120, an activation zone 130, and a cooling zone 140.

[0065] In this embodiment, the multiple fixing discs 200 can effectively improve the stability of fixing the activation cylinder 300 and prevent the activation cylinder 300 from deflecting or bending. In addition, the multiple fixing discs 200 divide the inner cavity of the main cylinder 100 into a preheating zone 110, a carbonization zone 120, an activation zone 130 and a cooling zone 140 along the axial direction, which can adapt to the heating or cooling needs of the carbon material activation treatment device at multiple temperature stages.

[0066] Specifically, the activation process of carbon materials typically involves multiple temperature stages: in the preheating stage, the material is gradually heated from room temperature to approximately 300 degrees Celsius to remove moisture and low-boiling-point volatiles; in the carbonization stage, the material is heated to 400 to 700 degrees Celsius to undergo a pyrolysis reaction and form a preliminary porous structure; in the activation stage, the material is heated to 800 to 1000 degrees Celsius to undergo a pore-forming reaction under the action of an activator; and in the cooling stage, the high-temperature material needs to be cooled to below a safe temperature before it can be discharged.

[0067] In traditional single-chamber activation furnaces, all these stages are completed within the same space. Due to the temperature gradient within the furnace, materials at different locations experience different temperature profiles, resulting in uneven activation. For example, materials near the heat source inlet may be overheated, while materials farther from the heat source inlet may be underheated. Furthermore, to meet the high-temperature requirement of 130°C in the activation zone, the entire furnace needs to be heated to a high temperature, leading to energy waste.

[0068] This embodiment solves the aforementioned problem by dividing the inner cavity of the main cylinder 100 into multiple independent temperature zones using multiple fixed disks 200. Each fixed disk 200 forms an independent chamber, and the spacing between adjacent fixed disks 200 is determined according to the length requirements of each zone. The preheating zone 110 is located near the feed end of the main cylinder 100, the carbonization zone 120 is adjacent to the preheating zone 110, the activation zone 130 is adjacent to the carbonization zone 120, and the cooling zone 140 is located near the discharge end of the main cylinder 100. Each temperature zone can be independently equipped with a heating device and a temperature detection device to control its own temperature. The material passes sequentially through the preheating zone 110, carbonization zone 120, activation zone 130, and cooling zone 140 with the activation cylinder 300, undergoing a heat treatment process matching the temperature of each zone. Because the temperature zones are isolated by the fixed disks 200, heat exchange between the zones is suppressed, allowing for more precise temperature control in each zone. In this way, as the material moves along the activation cylinder 300, its temperature gradually rises to the activation temperature, and then decreases before being discharged. This achieves continuous zoned processing, which not only ensures the uniformity of the activation effect but also improves energy utilization efficiency.

[0069] Combination Figure 5 In one embodiment, the carbon material activation treatment apparatus further includes a gas supply heating system 600. The gas supply heating system 600 includes a steam generator 610, a gas heating unit 620, and an auxiliary electric heating element 630.

[0070] The steam generator 610 has a first outlet 611 and a second outlet 612. The first outlet 611 is used to output steam, and the second outlet 612 is used to output flue gas. Exemplarily, the steam generator 610 has a combustion chamber inside, where fuel burns to produce high-temperature flue gas, and the heat generated by the combustion heats water into steam. The first outlet 611 is connected to multiple activation cylinders 300, allowing the steam to act as an activator and react with carbon materials within the activation cylinders 300. The flue gas output from the second outlet 612 has a temperature of 800 to 1000 degrees Celsius and contains a large amount of residual heat.

[0071] The gas heating unit 620 is located inside the main cylinder 100. The gas heating unit 620 includes a distribution plate 621, heating tubes 622, and a manifold 623. The distribution plate 621 is adjacent to the fixed plate 200 located between the activation zone 130 and the cooling zone 140. The manifold 623 is located in the preheating zone 110, specifically on the side of the preheating zone 110 away from the carbonization zone 120. Both the distribution plate 621 and the manifold 623 are disc-shaped structures, with their outer diameter matching the inner diameter of the main cylinder 100. The distribution plate 621 has a distribution channel connected to the second outlet 612 for receiving high-temperature flue gas generated by the steam generator 610. The manifold 623 has a manifold channel connected to the exhaust pipe 640. Multiple heating tubes 622 are provided, positioned between multiple activation cylinders 300 and passing through the second mounting hole 220 of the fixed plate 200. The two ends of the heating tube 622 are connected to the distribution plate 621 and the manifold plate 623 respectively, and the inner cavity of the heating tube 622 is connected to the distribution channel and the manifold channel. During the rotation of the main cylinder 100, the gas heating unit 620 rotates synchronously with the main cylinder 100, the fixed plate 200 and the activation cylinder 300. Both the distribution plate 621 and the manifold plate 623 can be connected to external pipelines through rotary joints.

[0072] After exiting the second outlet 612 of the steam generator 610, the high-temperature flue gas enters the distribution channel of the distribution plate 621 and is then distributed to each heating tube 622. As the flue gas flows within the heating tubes 622, it radiates and conducts heat to the surroundings through the tube walls. Since the heating tubes 622 are arranged between the activation cylinders 300 and pass through the fixed plate 200, they are in close proximity to the activation cylinders 300. The activation cylinders 300 absorb the heat radiated by the heating tubes 622, their temperature rises, and they transfer the heat to the materials inside. After passing through the heating tubes 622, the flue gas temperature decreases, and it gathers in the confluence channel of the manifold plate 623 before being discharged through the exhaust pipe 640.

[0073] This arrangement enables the tiered utilization of flue gas heat: the high-temperature flue gas is first used to heat the activation zone 130, because the activation zone 130 requires the highest temperature; as the flue gas flows from the activation zone 130 to the carbonization zone 120 and the preheating zone 110, the temperature gradually decreases to match the temperature required by these zones.

[0074] Auxiliary electric heating elements 630 are respectively disposed in the preheating zone 110, carbonization zone 120, and activation zone 130. The auxiliary electric heating elements 630 can be resistance heating wires or ceramic heating plates, etc., and are installed close to the activation cylinder 300, for example, on the outer wall of the activation cylinder 300 or the outer wall of the heating tube 622. The auxiliary electric heating elements 630 are electrically connected to the control unit 730, which is connected to the temperature sensors disposed in each zone. The temperature sensors can be disposed close to the activation cylinder 300, for example, on the activation cylinder 300 or the heating tube 622. The control unit 730 controls the opening and closing of the auxiliary electric heating elements 630 or adjusts their heating power based on the deviation between the temperature value detected by the temperature sensors in each zone and the set value. When the heat provided by the flue gas is insufficient to maintain the set temperature, the auxiliary electric heating elements 630 are activated for supplementary heating; when the heat provided by the flue gas is sufficient, the auxiliary electric heating elements 630 are turned off to save energy.

[0075] When the auxiliary electric heating element 630 is installed inside the main cylinder 100, such as on the outer wall of the activation cylinder 300 or the outer wall of the heating tube 622, it needs to rotate synchronously with the main cylinder 100, the fixed plate 200, and the activation cylinder 300. It can be connected to the external circuit through a slip ring installed on the main cylinder 100. Meanwhile, to improve the service life of the auxiliary electric heating element 630, the connecting wire of the auxiliary electric heating element 630 located inside the main cylinder 100 can be made of high-temperature resistant material or covered with a high-temperature resistant insulation layer. For example, it can be a ceramicized mineral insulated cable or a high-temperature resistant insulation layer covered with a ceramicized silicone rubber composite tape.

[0076] This embodiment achieves three functions simultaneously through the gas supply and heating system 600: first, it generates steam as an activator; second, it utilizes the waste heat of flue gas to heat the activation cylinder 300, realizing the cascade utilization of energy; and third, it ensures precise temperature control in each zone through the auxiliary electric heating element 630. Compared with the traditional solution that separately sets up a steam boiler and an electric heating activation furnace, this solution significantly reduces energy consumption and equipment investment.

[0077] Optionally, the pipes connecting the manifold 621 and the manifold 623 can be connected by rotary joints to accommodate the rotation of the manifold 621 and the manifold 623.

[0078] Optionally, a tensioning device 500 is provided in the second mounting hole 220, and the heating tube 622 is fixed in the second mounting hole 220 by the tensioning device 500.

[0079] Optionally, the heating tube 622 can be detachably connected to the distribution plate 621 and the manifold 623, for example, by means of threaded connection or snap-fit ​​connection, thereby facilitating the assembly and disassembly of the gas heating unit 620.

[0080] In some embodiments, the carbon material activation treatment apparatus further includes a cooling system. The cooling system is used to rapidly cool the high-temperature material that has completed the activation reaction to prevent over-activation or structural collapse due to slow cooling, while also facilitating subsequent material transportation and collection.

[0081] For example, the cooling system includes a cooling medium supply source, a cooling medium distribution pipe, and multiple cooling sleeves.

[0082] The cooling medium supply source is located outside the main cylinder 100 and is used to provide the cooling medium. The cooling medium can be cooling water, cooling air, or cooling oil. The cooling medium supply source can be a circulating cooling water tank, cooling tower, air compressor, or cooling oil pump, and its output end is equipped with a regulating valve to control the flow rate and pressure of the cooling medium. The cooling medium supply source is electrically connected to the control unit 730, which adjusts the supply of cooling medium according to the temperature detection value of the cooling zone 140.

[0083] The cooling medium distribution pipe is located outside or inside the main cylinder 100, with one end connected to the cooling medium supply source and the other end extending to the vicinity of the cooling zone 140. The cooling medium distribution pipe can be a metal hose or steel pipe connected to a rotary joint to accommodate the rotational movement of the main cylinder 100. When the cooling medium distribution pipe is located outside the main cylinder 100, the cooling medium is introduced into the main cylinder 100 through the rotary joint installed at the end of the main cylinder 100; when the cooling medium distribution pipe is located inside the main cylinder 100, it is fixedly connected to the main cylinder 100 and rotates with the main cylinder 100, and the cooling medium is transported from the stationary cooling medium supply source to the rotating distribution pipe through the rotary joint located at the end of the distribution pipe.

[0084] Optionally, multiple cooling sleeves are respectively fitted onto the outer wall of each activation cylinder 300 located in the cooling zone 140. The inner diameter of the cooling sleeve is larger than the outer diameter of the activation cylinder 300, forming an annular cooling medium flow channel between them. The axial length of the cooling sleeve matches the length of the cooling zone 140. Both ends of the cooling sleeve are sealed to the outer wall of the activation cylinder 300, which can be achieved by welding, flange connection, or clamp connection, and a sealing ring is provided at the connection to prevent cooling medium leakage. The cooling sleeve is provided with a cooling medium inlet and a cooling medium outlet. The cooling medium inlet is connected to a cooling medium distribution pipe, and the cooling medium outlet is connected to a drain pipe or an exhaust pipe.

[0085] The cooling medium flows from the cooling medium supply source and is transported through the cooling medium distribution pipe to the cooling medium inlet of each cooling sleeve, entering the annular flow channel between the cooling sleeve and the activation cylinder 300. As the cooling medium flows within the annular flow channel, it exchanges heat with the high-temperature outer wall of the activation cylinder 300. The high-temperature material inside the activation cylinder 300 transfers heat to the outer wall of the activation cylinder 300 through the cylinder wall, and the outer wall of the activation cylinder 300 then transfers heat to the cooling medium. After absorbing heat, the cooling medium's temperature rises, and it flows out from the cooling medium outlet, being discharged through a drain pipe or an exhaust pipe. The discharged cooling medium can be recycled after cooling treatment, or its residual heat can be used for preheating in the preheating zone 110, achieving waste heat recovery.

[0086] As the high-temperature material inside the activation cylinder 300 moves through the cooling zone 140, heat is continuously transferred to the cooling medium through the cylinder wall, gradually reducing the material temperature. Because the cooling sleeve covers the entire cooling zone 140 and the cooling medium flows continuously, the temperature distribution in the cooling zone 140 is uniform, enabling the material to cool evenly. The flow rate and temperature of the cooling medium can be adjusted according to cooling requirements: when rapid cooling is needed, the flow rate of the cooling medium is increased or the inlet temperature of the cooling medium is decreased; when gradual cooling is needed, the flow rate of the cooling medium is decreased or the inlet temperature of the cooling medium is increased.

[0087] In some other embodiments, the cooling system includes an air supply device, which may be a fan or the like. The air outlet of the air supply device faces the cooling zone 140, and the airflow generated by the air supply device can be blown into the cooling zone 140 to cool the activation cylinder 300 and the material inside the activation cylinder 300.

[0088] The cooling system can rapidly cool the material after the activation reaction is completed, terminate the activation reaction in time, and prevent the material from being over-activated due to prolonged residence time in the high-temperature zone. Over-activation will lead to collapse of the pore structure, decrease in specific surface area, and reduction in product strength. In addition, cooling the high-temperature material to below the safe temperature facilitates subsequent material transportation, collection and packaging, and avoids damage to the transportation equipment and operators caused by the high-temperature material.

[0089] Combination Figures 6 to 8 In one embodiment, the carbon material activation treatment apparatus further includes a composite drive system 700. The composite drive system 700 includes a tilt adjustment mechanism 710, a rotation drive mechanism 720, and a control unit 730.

[0090] The tilt adjustment mechanism 710 is connected to the main cylinder 100 and is used to adjust the tilt angle of the main cylinder 100's axis relative to the horizontal plane. The tilt adjustment mechanism 710 includes a tilt sensor 711, a first support ring 712, a base 713, at least two second support rings 714, and at least two lifting drive components 715. The tilt sensor 711 is mounted on the main cylinder 100 and can be an electronic level, accelerometer, or gyroscope. It is used to detect the tilt angle of the main cylinder 100 in real time and send the detection signal to the control unit 730. The first support ring 712 is rotatably sleeved on the outer side of the middle portion of the main cylinder 100. A bearing is provided between the first support ring 712 and the main cylinder 100, allowing the main cylinder 100 to rotate freely within the first support ring 712. The first support ring 712 forms an axial limit with the main cylinder 100, for example, by providing a shoulder on the main cylinder 100 or a retaining ring inside the support ring, to prevent the main cylinder 100 from moving axially. The base 713 is fixedly mounted on the mounting base surface, and the base 713 is hinged to the first support ring 712 via a hinge shaft, allowing the first support ring 712 and the main cylinder 100 to rotate around the hinge shaft. At least two second support rings 714 are positioned on either side of the first support ring 712 along the axial direction of the main cylinder 100. The second support rings 714 are slidably sleeved on the outside of the main cylinder 100, and a sliding bearing or wear-resistant bushing is provided between the second support rings 714 and the main cylinder 100, allowing the main cylinder 100 to rotate within the second support rings 714 while sliding axially. At least two lifting drive components 715 are vertically mounted on the mounting base surface and hinged to each of the second support rings 714 in a one-to-one correspondence. The lifting drive component 715 can be a hydraulic cylinder, an electric push rod, or a screw jack. It is electrically connected to the control unit 730 and performs lifting actions according to the instructions of the control unit 730.

[0091] When the lifting drive component 715 moves up and down, it drives the corresponding second support ring 714 to move up and down. Since the first support ring 712 is hinged to the base 713, the up and down movement of the second support ring 714 causes the main cylinder 100 to rotate around the hinge point between the first support ring 712 and the base 713, thereby changing the tilt angle of the main cylinder 100. When the tilt angle of the main cylinder 100 changes, the moving speed of the material in the activation cylinder 300 changes accordingly. The larger the tilt angle, the faster the axial movement speed of the material under the action of gravity, and the shorter the residence time; the smaller the tilt angle, the slower the movement speed and the longer the residence time. The tilt angle sensor 711 monitors the tilt angle in real time and feeds it back to the control unit 730. The control unit 730 controls the amount of action of the lifting drive component 715 according to the deviation between the preset value and the feedback value, realizing precise closed-loop control of the tilt angle.

[0092] A rotary drive mechanism 720 is connected to the main cylinder 100 and is used to drive the main cylinder 100 to rotate axially. The rotary drive mechanism 720 includes a drive motor 721, a driven gear 722, and a driving gear 723. The drive motor 721 is fixedly connected to the first support ring 712. The drive motor 721 can be a variable frequency speed control motor and is electrically connected to the control unit 730. The control unit 730 controls the rotational speed of the drive motor 721 by adjusting the power supply frequency of the drive motor 721. The driven gear 722 is coaxially fixed to the outside of the main cylinder 100. The driven gear 722 can be fixed to the main cylinder 100 by welding, keying, or bolting. The driving gear 723 is coaxially fixed to the outside of the motor shaft of the drive motor 721 and meshes with the driven gear 722. When the drive motor 721 rotates, the driving gear 723 drives the driven gear 722 to rotate, and the driven gear 722 drives the main cylinder 100 to rotate around its own axis. Since the drive motor 721 is fixed on the first support ring 712, when the tilt adjustment mechanism 710 adjusts the tilt angle of the main cylinder 100, the drive motor 721 tilts synchronously with the first support ring 712. The relative position of the drive gear 723 and the driven gear 722 remains unchanged, so they always maintain a good meshing state.

[0093] The control unit 730 is electrically connected to the tilt adjustment mechanism 710 and the rotary drive mechanism 720, respectively. Optionally, the control unit 730 can be a programmable logic controller, a microcontroller, or an industrial computer. The control unit 730 receives the tilt angle signal fed back by the tilt sensor 711 and the rotation speed signal fed back by the speed sensor, and issues control commands to the lifting drive component 715 and the drive motor 721 according to preset process parameters.

[0094] The material turning effect of the turning rack 400 is affected by the tilt angle and rotation speed of the main cylinder 100. The composite drive system 700 of this embodiment allows the tilt angle and rotation speed of the main cylinder 100 to be adjusted as needed. The composite drive system 700 of this embodiment can flexibly adjust the tilt angle and rotation speed of the main cylinder 100 while meeting the activation requirements of carbon materials, which is conducive to achieving a better material turning effect of the turning rack 400 and improving the contact efficiency between carbon materials and activators.

[0095] Furthermore, the composite drive system 700 enables the carbon material activation treatment device to adapt to different material characteristics and process requirements, significantly improving the device's process adaptability. For example, increasing the tilt angle while decreasing the rotation speed allows the material to pass through quickly with weak agitation, suitable for fragile materials; decreasing the tilt angle while increasing the rotation speed allows the material to pass through slowly with strong agitation, suitable for materials that are difficult to activate.

[0096] It is understandable that during long-term use, the carbon material activation treatment device may experience material accumulation in the gaps at the front and rear ends of the main cylinder 100 or adhere to the surface of the turning rack 400, which affects production efficiency and production quality. To solve this problem, the carbon material activation treatment device of this application embodiment further provides a structural solution that can achieve internal cleaning.

[0097] For example, combined Figure 9 The carbon material activation treatment device also includes a cleaning medium generator 800, a material supply system 810, a distributor 820, a feed end cover 830, a discharge end cover 840, and a control valve group 850.

[0098] The cleaning medium generator 800 is used to generate the cleaning medium. The cleaning medium can be high-temperature and high-pressure steam, high-pressure hot water, or chemical cleaning liquid, etc. When high-temperature and high-pressure steam is used as the cleaning medium, the cleaning medium generator 800 can be the aforementioned steam generator 610, achieving dual use in one device.

[0099] The material supply system 810 is used to supply carbon materials to be activated. The material supply system 810 may include a hopper, a conveying pipeline, and a metering device for continuously conveying the carbon materials into the device according to a set ratio. The conveying pipeline of the material supply system 810 may include at least one section of flexible pipe, such as a corrugated pipe, to accommodate adjustments in the tilt angle of the main cylinder 100.

[0100] The distributor 820 is fixed inside the main cylinder 100. The distributor 820 is funnel-shaped or conical, with its larger end facing the feed end cover 830 and its smaller end having multiple distribution holes 821. The number of distribution holes 821 is equal to the number of activation cylinders 300, and the circumferential positions of the distribution holes 821 correspond one-to-one with the circumferential positions of the activation cylinders 300. Each distribution hole 821 of the distributor 820 is connected to the corresponding activation cylinder 300, used to evenly distribute the incoming material to each activation cylinder 300.

[0101] The feed end cap 830 is rotatably connected to the front end of the main cylinder 100. A rotary seal (not shown in the figure) is provided between the feed end cap 830 and the main cylinder 100 to prevent material leakage and air ingress. Since the rotary seal is a mature technology in the prior art and is not an improvement solution of this application, it will not be described in detail. In other words, any rotary seal structure that can achieve the rotary seal between the feed end cap 830 and the front end of the main cylinder 100 in this embodiment is acceptable. The feed end cap 830, the main cylinder 100, and the distributor 820 form a distribution chamber, which is connected to the distribution hole 821. The feed end cap 830 has a first inlet 831 and a second inlet 832. The first inlet 831 is connected to the cleaning medium generator 800, and the second inlet 832 is connected to the material supply system 810.

[0102] The discharge end cap 840 is rotatably connected to the end of the main cylinder 100. A rotary seal (not shown in the figure) is also provided between the discharge end cap 840 and the main cylinder 100. The discharge end cap 840 has a discharge port 841 and a drain port 842. The discharge port 841 is used to discharge the activated product, and the drain port 842 is used to discharge the cleaning waste liquid.

[0103] The control valve assembly 850 connects the first inlet 831, the second inlet 832, the discharge port 841, and the drain port 842. The control valve assembly 850 includes a first control valve 851, a second control valve 852, a third control valve 853, and a fourth control valve 854, which respectively control the opening and closing of the first inlet 831, the second inlet 832, the discharge port 841, and the drain port 842. The first control valve 851, the second control valve 852, the third control valve 853, and the fourth control valve 854 can be ball valves, butterfly valves, or solenoid valves, etc. The control valve assembly 850 is electrically connected to the control unit 730, which controls the on / off state of each valve according to the operating mode.

[0104] The device has two operating modes: production mode and cleaning mode. In production mode, the control unit 730 controls the control valve group 850 to open the second inlet 832 and the discharge port 841, and close the first inlet 831 and the drain port 842. The material supply system 810 feeds the carbon material to be activated and the activator into the distribution chamber through the second inlet 832, and the distributor 820 evenly distributes the material into each activation cylinder 300. After the material completes the activation treatment in the activation cylinder 300, the product is discharged from the end of the activation cylinder 300 and collected through the discharge port 841 of the discharge end cover 840. In cleaning mode, the control unit 730 controls the control valve group 850 to close the second inlet 832 and the discharge port 841, and open the first inlet 831 and the drain port 842. The cleaning medium generated by the cleaning medium generator 800 enters the distribution chamber and each activation cylinder 300 through the first inlet 831. The cleaning medium flushes the inner wall of the activation cylinder 300 and the turning rack 400, removing adhering coke and residual materials. The waste liquid after cleaning, carrying the removed materials, is discharged from the drain port 842. The cleaning process can be performed periodically after a period of continuous production, or when changing material types.

[0105] It is understandable that when the cleaning medium generator 800 is a steam generator 610, the steam generator 610 operates in both production and cleaning modes. For example, the first outlet 611 of the steam generator 610 is connected to the first inlet 831 of the feed end cover 830, through which the activator and cleaning medium are supplied. In this case, the first inlet 831 is open in both production and cleaning modes, and is closed only when production stops. Alternatively, the first outlet 611 of the steam generator 610 is connected to the first inlet 831 of the feed end cover 830 and a third inlet provided on the feed end cover 830, through which the cleaning medium is supplied and the activator is supplied. In this case, the third inlet is open and the first inlet 831 is closed in production mode, and the third inlet is closed and the first inlet 831 is open in cleaning mode.

[0106] The cleaning system in this embodiment can clean the inside of the activation cylinder 300 without disassembling the equipment, which greatly reduces downtime for maintenance and improves the continuous operating efficiency of the equipment.

[0107] In one embodiment, a shearing member 900 is fixedly installed at the end of the main cylinder 100. The shearing member 900 is cross-shaped, star-shaped, or spiral-shaped, and is arranged perpendicular to the axis of the main cylinder 100. The shearing member 900 can be fixed to the inner wall or end face of the end of the main cylinder 100 by bolt connection or welding. When the activated material is discharged from the end of the main cylinder 100, it may agglomerate due to the temperature drop in the cooling zone 140. The shearing member 900 cuts the discharged material, breaking up large agglomerates into smaller particles to prevent blockage of the discharge port 841.

[0108] In one embodiment, the carbon material activation treatment device further includes an anti-clogging system. The anti-clogging system is installed at the feed end and discharge end of the main cylinder 100 to prevent the carbon material to be activated from forming bridging blockages in the feed end distributor 820, and to prevent the activated finished product from accumulating and clogging at the discharge end, thereby achieving synchronous unblocking and linkage between feeding and discharging.

[0109] In the carbon material activation process, the carbon material to be activated is usually in powder or granular form, with a particle size ranging from 0.5 mm to 5 mm. When this type of material flows within the distributor 820, the overlapping of particles can easily cause blockages in the distributor holes 821 and the discharge end of the distributor 820. The anti-clogging system of this embodiment is used to solve the above-mentioned problem.

[0110] Optionally, the anti-clogging system includes an anti-bridging device at the feed end, which is disposed on one side of the distribution hole 821 of the distributor 820 to disrupt the bridging structure formed by the material above the distribution hole 821. Exemplarily, the anti-bridging device at the feed end includes a vibrator and an airflow disturbance nozzle. The vibrator is disposed on the outer wall of the distributor 820. The vibrator can be an electromagnetic vibrator or a pneumatic vibrator, and its vibration frequency and amplitude can be adjusted. When the vibrator operates, the vibration is transmitted to the material through the wall of the distributor 820, causing relative motion in the material particles and disrupting the bridging structure. The vibration mode of the vibrator can be continuous vibration or intermittent vibration. The airflow disturbance nozzle is disposed on the inner wall of the distributor 820, located on one side of the distribution hole 821, and connected to a compressed air source. The airflow disturbance nozzle sprays gas towards the distribution hole 821, and is used to spray gas into the material layer; this gas can be steam, compressed air, or nitrogen, etc. High-pressure gas creates localized fluidization zones within the material layer, disrupting the friction between particles and causing the material to flow again. The airflow disturbance nozzles can employ pulse jetting, with each nozzle independently controlled and jetting sequentially, creating a moving airflow disturbance zone within the distributor 820.

[0111] Multiple vibrators and airflow disturbance nozzles can operate in a polling mode, that is, they operate sequentially in a preset order to avoid interference caused by multiple devices operating simultaneously, while maintaining a continuous anti-bridging effect.

[0112] Optionally, the anti-clogging system includes a discharge end anti-clogging device. The discharge end anti-clogging device is located inside the discharge end cover 840 and is used to prevent activated material from accumulating and clogging at the discharge port 841. The discharge end anti-clogging device includes a rotary scraper, an air hammer, and a negative pressure device.

[0113] A rotary scraper is disposed on the inner wall of the discharge end cover 840, above the discharge port 841. The rotary scraper has a star-shaped or spiral structure, and its rotating shaft passes through the wall of the discharge end cover 840 and is connected to the scraper drive motor 721. The scraper drive motor 721 is electrically connected to the control unit 730. The rotary scraper rotates continuously inside the discharge end cover 840, and its blades are close to the inner wall of the discharge end cover 840 and the edge of the discharge port 841, scraping off the material adhering to the inner wall and breaking up the material accumulated above the discharge port 841, allowing the material to fall smoothly into the discharge port 841.

[0114] The air hammer is installed on the outer wall of the discharge end cover 840, near the discharge port 841. Driven by compressed air, the air hammer generates a high-intensity impact force. The shock wave is transmitted through the wall of the discharge end cover 840 to the internal material, dispersing any blockages. The air hammer can operate in a timed mode, for example, once every ten minutes, with each impact consisting of three to five consecutive strikes.

[0115] A negative pressure suction port is provided on the top of the discharge end cover 840. A negative pressure device is connected to the negative pressure suction port and electrically connected to the control unit 730. Specifically, the negative pressure device includes a vacuum pump, a filter, and a control valve, which are electrically connected to the control unit 730. When the discharge port 841 becomes blocked, the control unit 730 opens the control valve of the negative pressure device. The vacuum pump generates negative pressure inside the discharge end cover 840 through the negative pressure suction port, sucking up the blocked material, breaking up the blockage structure. Then, the material falls back down under gravity and is discharged from the discharge port 841. The negative pressure suction port is also used to extract activation exhaust gas, creating a micro-negative pressure environment inside the discharge end cover 840 to prevent activation gas from leaking from the discharge port 841.

[0116] The control unit 730 is electrically connected to both the feed-end anti-bridging device and the discharge-end anti-blocking device, and is used to control the operating status of these devices. The control unit 730 is also connected to the composite drive system 700 and the gas supply and heating system 600. The control unit 730 is configured to: stop feeding or reduce the feed rate at the feed end when blockage occurs at the discharge end to prevent further deterioration of the blockage; and resume normal feeding at the feed end after the blockage is cleared.

[0117] Specifically, the control unit 730 monitors the material accumulation height inside the discharge end cover 840 in real time. This can be achieved, for example, by using a level sensor installed inside the discharge end cover 840. The level sensor can be a rotary paddle level switch, a capacitive level sensor, or a radar level gauge. When the material accumulation height exceeds a first threshold, the control unit 730 determines that the discharge port 841 is about to become blocked, issues a warning signal, and controls the anti-bridging device at the feed end to enter a standby state. At the same time, it sends a command to the composite drive system 700 to reduce the rotation speed of the main cylinder 100, thereby slowing down the material conveying speed to the discharge end.

[0118] When the detected material accumulation height exceeds the second threshold, the control unit 730 determines that the discharge port 841 is blocked, issues a stop feeding command to the feed end anti-bridging device, closes the valve of the material supply system 810, and stops supplying new material to the activation cylinder 300; simultaneously, it activates the discharge end anti-blocking device, and sequentially or simultaneously activates the rotary scraper, air hammer, and negative pressure device to perform enhanced unblocking operations. During the unblocking operation, the control unit 730 continuously monitors the material accumulation height. When the accumulation height drops below the first threshold, it determines that the blockage has been cleared, resumes material supply to the feed end, and returns the discharge end anti-blocking device to standby mode.

[0119] The control unit 730 also records the frequency and severity of blockage events. When multiple blockages occur in a short period of time, the control unit 730 issues an alarm to the operator, prompting them to check whether there is a structural blockage at the outlet of the activation cylinder 300 or whether there are foreign objects inside the discharge end cover 840.

[0120] The anti-clogging system in this embodiment effectively breaks the bridging structure formed above the material distribution hole 821 by the anti-bridging device at the feed end, ensuring a uniform and stable supply of material to each activation cylinder 300 and avoiding the problem of some activation cylinders 300 running empty due to material interruption. In addition, the anti-clogging device at the discharge end effectively prevents the accumulation and blockage of activated material at the discharge port 841, ensuring smooth discharge and maintaining stable pressure inside the main cylinder 100.

[0121] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
