Description

Technical Field

[0001] This invention relates to the field of activation furnace technology, and in particular to an environmentally friendly fruit shell activated carbon activation furnace. Background Technology

[0002] Activated carbon from fruit shells, as a high-performance adsorbent material, is widely used in environmental protection, chemical, food, and pharmaceutical fields due to its well-developed pores, large specific surface area, and strong adsorption capacity. The traditional production process of activated carbon from fruit shells mainly includes two key steps: carbonization and activation. Carbonization involves high-temperature pyrolysis of the fruit shells under anaerobic or oxygen-free conditions, which initially forms a porous structure. Activation, on the other hand, involves further expanding and opening the pores at even higher temperatures through physical or chemical methods to improve its adsorption performance. Currently, common activation equipment often uses rotary kilns or vertical activation furnaces. However, existing equipment still has many shortcomings in actual operation: First, the carbonization and activation processes are often separated into different equipment or areas, requiring material transfer in between, resulting in significant heat loss, high energy consumption, and the introduction of external impurities, affecting product purity. Second, the combustible gases generated during carbonization are usually directly emitted or simply burned, failing to be effectively recovered and utilized, causing energy waste and failing to meet environmental protection requirements. Furthermore, traditional equipment has poor control over material agitation and heating uniformity, easily leading to uneven carbonization or activation, affecting the final quality of the activated carbon. In the activation stage, steam is a commonly used physical activator. However, the uniformity of its mixing with materials, heating efficiency, and the stability of the reaction temperature directly affect the activation effect, and the control precision of existing equipment in this regard often needs improvement. Furthermore, existing equipment relies heavily on manual operation or simple valve switching for the connection between carbonization and activation processes, making it difficult to guarantee sealing and resulting in low automation, hindering continuous and efficient batch production. This intermittent operation not only leads to low production efficiency but also increases energy consumption and labor costs. Therefore, there is an urgent need to develop an environmentally friendly coconut shell activated carbon activation equipment that integrates carbonization and activation, enabling efficient utilization of thermal energy, recovery of combustible gases, automated control, and ensuring product quality stability. This would address the problems of high energy consumption, significant pollution, low efficiency, and poor product consistency in existing technologies. Summary of the Invention

[0003] To address the aforementioned technical problems, the present invention adopts the following technical solution: an environmentally friendly fruit shell activated carbon activation furnace, comprising an activation mechanism for activating carbonized fruit shells, wherein the activation mechanism comprises a furnace body, a burner is fixedly installed on the furnace body, an activation chamber and a middle sealing plate are fixedly installed inside the furnace body, and the activation mechanism is provided with a carbonization mechanism for carbonizing fruit shells and a separation mechanism for separating the carbonization mechanism and the activation mechanism. The carbonization mechanism includes a conveying shaft rotatably mounted inside the furnace body, a conveying gear fixedly mounted on the conveying shaft, and a carbonization cylinder rotatably mounted inside the furnace body.

[0004] Furthermore, the activation mechanism includes a closed cylinder fixedly installed inside the furnace body. The furnace body is provided with a combustion chamber, a combustion ring chamber, a hot water chamber, and a steam chamber. The combustion chamber is connected to the combustion ring chamber. The combustion ring chamber surrounds the outside of the hot water chamber and the steam chamber. A steam trap is provided between the steam chamber and the hot water chamber. The hot water chamber is filled with water. The combustion chamber is located below the closed cylinder. The carbonization cylinder rotates inside the closed cylinder.

[0005] Furthermore, multiple heating rods are fixedly installed on the steam chamber, and the heating rods extend into the activation chamber. There is a gap between the heating rods and the activation chamber. The activation chamber is conical in shape, and an openable sealing plate is fixedly installed on the furnace body.

[0006] The burner delivers heat to the combustion chamber and the combustion ring chamber. The heat in the combustion chamber heats the carbonization cylinder, and the heat in the combustion ring chamber heats and evaporates the water in the hot water chamber. The steam enters the steam chamber through the steam trap and then enters the activation chamber through the gap between the heating rod and the activation chamber. The heating rod heats the activation chamber at a high temperature, and the steam acts as an activator, mixing with the carbonized fruit shells in the activation chamber and heating them together to activate the fruit shells. Once activation is complete, the fruit shells slide along the inner wall of the activation chamber to the sealing plate. Opening the sealing plate allows the finished product to be removed.

[0007] Furthermore, the carbonization mechanism also includes a feed hopper fixedly installed on the furnace body, a feed inlet provided on the carbonization cylinder, the feed inlet being located below the feed hopper, a turning gear fixedly installed on the carbonization cylinder, a turning motor fixedly installed on the furnace body, a motor gear fixedly installed on the motor shaft of the turning motor, the motor gear meshing with the turning gear, and a conveying shaft extending into the carbonization cylinder.

[0008] Furthermore, the burner is equipped with a return gas pipe, which is connected to the carbonization cylinder.

[0009] During operation, fruit shells are fed into the hopper and then into the carbonization cylinder through the feed inlet. After feeding, the middle sealing plate, lower sealing plate, and upper sealing plate seal the carbonization cylinder, and the feed sealing plate seals the feed hopper. The heat in the combustion chamber heats the carbonization cylinder, thus carbonizing the fruit shells inside. The turning motor drives the motor gear to rotate, which in turn rotates the turning gear and the carbonization cylinder, ensuring that the fruit shells inside the carbonization cylinder are heated evenly, improving the carbonization effect. The combustible gas produced by the carbonization of the fruit shells enters the burner through the return gas pipe for combustion, avoiding direct emission of the gas produced by the carbonization of the fruit shells and improving environmental protection.

[0010] Once the fruit shells are carbonized, the lower sealing plate, upper sealing plate, and feed sealing plate are opened, and the conveying gear drives the conveying shaft to rotate, transporting the carbonized fruit shells to the activation chamber for activation.

[0011] Furthermore, the separating mechanism includes a switching motor fixedly mounted on the furnace body, a half-tooth gear fixedly mounted on the motor shaft of the switching motor, an internal half-tooth gear rotatably mounted on the furnace body, an external gear fixedly mounted on the internal half-tooth gear, a bidirectional lead screw rotatably mounted on the furnace body, and a lead screw gear fixedly mounted on the bidirectional lead screw. The half-tooth gear meshes with the external gear. When the internal half-tooth gear meshes with the conveying gear, the internal half-tooth gear disengages from the lead screw gear. When the internal half-tooth gear meshes with the lead screw gear, the internal half-tooth gear disengages from the conveying gear.

[0012] Furthermore, a sliding seat is slidably installed on the furnace body, and the sliding seat forms a threaded drive with the bidirectional lead screw. A push rod is fixedly installed on the sliding seat, and a feed sealing plate is fixedly installed on the push rod. A sealing spring is provided between the feed sealing plate and the furnace body. A vertical frame is fixedly installed on the furnace body, and two lifting blocks are slidably installed on the vertical frame. An active rotating rod is rotatably installed on the sliding seat, and the active rotating rod is rotatably installed with the lifting blocks. An upper rotating rod is rotatably installed on the lifting blocks, and a lower arc rod is rotatably installed on the upper rotating rod. A sealing block is slidably installed at the bottom of the furnace body, and the sealing block is rotatably installed with the two lower arc rods.

[0013] Furthermore, a lower sealing plate is fixedly installed on the sealing block, the lower sealing plate slides within the middle sealing plate, an upper sealing plate is slidably installed within the middle sealing plate, a lower rack is fixedly installed on the lower sealing plate, an upper rack is fixedly installed on the upper sealing plate, three sealing gears are rotatably installed within the middle sealing plate, adjacent sealing gears mesh with each other, the lower rack meshes with the sealing gear located on the left, and the sealing gear located on the right meshes with the upper rack, and the upper and lower sealing plates are provided with semi-circular arcs to avoid the conveyor shaft.

[0014] The motor drives the half-gear to rotate, which in turn drives the internal and external half-gears to rotate intermittently. When the internal half-gear meshes with the conveying gear, it disengages from the lead screw. At this time, the push rod drives the conveying gear and the conveying shaft to rotate, and the feed sealing plate, lower sealing plate, and upper sealing plate are in the open state. After the internal half-gear disengages from the conveying gear, it begins to mesh with the lead screw. At this time, the carbonized fruit shells have been conveyed to the activation chamber, and the next batch of fruit shells to be carbonized is placed into the carbonization cylinder. At this time, the internal half-gear drives the lead screw and the double-acting lead screw to rotate. The double-acting lead screw drives the sliding seat to slide along the furnace body. The sliding seat drives the push rod and the feed sealing plate to move towards the feed hopper. At the same time, the sliding seat drives the lifting block to rise along the upright frame through the active rotating rod, and drives the sealing block and lower sealing plate to rise through the upper rotating rod and the lower arc rod. The lower sealing plate drives the sealing gear to rotate through the lower rack. The upper rack and upper sealing plate descend, causing the lower sealing plate to rise while the upper sealing plate descends. When the sliding seat moves to the end of the double-acting screw, the half-tooth gear disengages from the external gear, causing the internal half-tooth gear to stop rotating. At this time, the feed sealing plate closes the feed hopper, and the lower and upper sealing plates separate the activation chamber from the carbonization cylinder. Carbonization takes place in the carbonization cylinder, and activation takes place in the activation chamber. When the half-tooth gear meshes with the external gear again, the internal half-tooth gear drives the double-acting screw to rotate. Since the double-acting screw has a double-acting external thread, the sliding seat begins to move in the direction of the screw and gear to reset. When the half-tooth gear disengages from the external gear again, the sliding seat returns to its initial position. At this time, the feed sealing plate, lower sealing plate, and upper sealing plate are fully open. When the half-tooth gear meshes with the external gear again, the internal half-tooth gear begins to mesh with the conveying gear, conveying the carbonized fruit shells in the carbonization cylinder to the activation chamber, and so on.

[0015] The beneficial effects of this invention compared with the prior art are: (1) This invention integrates the carbonization mechanism and the activation mechanism into the same furnace body, and uses the heat generated by the burner to provide heat energy for both carbonization and steam preparation, thereby realizing the cascade and comprehensive utilization of energy. The heat energy utilization rate is high, and the energy consumption is significantly reduced. In particular, by setting a return gas pipe to return the combustible gas generated during the carbonization process to the burner as fuel, the recycling of waste resources is realized. This avoids environmental pollution caused by the direct emission of harmful gases and reduces the dependence on additional fuel, resulting in outstanding environmental protection and energy-saving benefits; (2) This invention realizes the automatic and alternating sealing and material transfer of the two stations of carbonization and activation through a set of ingenious separation mechanisms driven by switching motors. Through the ingenious design of half-tooth gears and internal half-tooth gears, the power is intermittently distributed to the conveying shaft and the bidirectional screw, realizing the carbonization process. The fully automatic cycle of carbonization, discharge, sealing and activation not only eliminates the manual operation links in the traditional intermittent production and greatly improves production efficiency, but also ensures the continuity and stability of the production process, laying the foundation for large-scale mass production; (3) The carbonization mechanism set in this invention is equipped with a rotatable carbonization cylinder driven by a flipping motor, which ensures that the shells are heated evenly during the carbonization process, providing carbonized materials of consistent quality for subsequent activation. Secondly, in the activation stage, the combustion ring chamber heats the hot water chamber to generate steam as an activator, and through the surrounding steam chamber and the heating rod extending into the conical activation chamber, the high-temperature steam and the material are fully and evenly mixed and heated. The conical activation chamber facilitates the material to slide naturally to the discharge port under the action of gravity, avoiding residue. These designs together ensure that the activation reaction is sufficient and uniform, and the final product has high adsorption performance and good batch stability. Attached Figure Description

Detailed Implementation

[0027] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0028] Example: Reference Figures 1-10 An environmentally friendly activated carbon furnace for fruit shells includes an activation mechanism for activating carbonized fruit shells. The activation mechanism includes a furnace body 101, a burner 102 fixedly installed on the furnace body 101, an activation chamber 107 and a middle sealing plate 112 fixedly installed inside the furnace body 101, and a carbonization mechanism for carbonizing fruit shells and a separation mechanism for separating the carbonization mechanism and the activation mechanism. The carbonization mechanism includes a conveying shaft 208 rotatably installed inside the furnace body 101, a conveying gear 209 fixedly installed on the conveying shaft 208, and a carbonization cylinder 201 rotatably installed inside the furnace body 101.

[0029] like Figures 3-5As shown, the activation mechanism includes a closed cylinder 111 fixedly installed inside the furnace body 101. The furnace body 101 is provided with a combustion chamber 103, a combustion ring chamber 104, a hot water chamber 105, and a steam chamber 109. The combustion chamber 103 is connected to the combustion ring chamber 104. The combustion ring chamber 104 surrounds the outside of the hot water chamber 105 and the steam chamber 109. A steam trap 106 is provided between the steam chamber 109 and the hot water chamber 105. The hot water chamber 105 is filled with water. The combustion chamber 103 is located below the closed cylinder 111. The carbonization cylinder 201 rotates inside the closed cylinder 111.

[0030] like Figures 3-5 As shown, multiple heating rods 108 are fixedly installed on the steam chamber 109. The heating rods 108 extend into the activation chamber 107. There is a gap between the heating rods 108 and the activation chamber 107. The activation chamber 107 is conical. An openable sealing plate 110 is fixedly installed on the furnace body 101.

[0031] The burner 102 delivers heat to the combustion chamber 103 and the combustion ring chamber 104. The heat in the combustion chamber 103 heats the carbonization cylinder 201, and the heat in the combustion ring chamber 104 heats and evaporates the water in the hot water chamber 105. The steam enters the steam chamber 109 through the steam trap 106. The steam enters the activation chamber 107 through the gap between the heating rod 108 and the activation chamber 107. The heating rod 108 heats the activation chamber 107 at a high temperature. The steam acts as an activator and enters the activation chamber 107 to mix with the carbonized fruit shells in the activation chamber 107 and heat them together to activate the fruit shells. After activation, the fruit shells slide along the inner wall of the activation chamber 107 to the sealing plate 110. Opening the sealing plate 110 allows the finished product to be removed.

[0032] like Figure 6 , Figure 7 As shown, the carbonization mechanism also includes a feed hopper 202 fixedly installed on the furnace body 101, a feed inlet 203 provided on the carbonization cylinder 201, the feed inlet 203 being located below the feed hopper 202, a turning gear 207 fixedly installed on the carbonization cylinder 201, a turning motor 204 fixedly installed on the furnace body 101, a motor gear 205 fixedly installed on the motor shaft of the turning motor 204, the motor gear 205 meshing with the turning gear 207, and a conveying shaft 208 extending into the carbonization cylinder 201.

[0033] like Figure 6 , Figure 7 As shown, the burner 102 is equipped with a return gas pipe 206, which is connected to the carbonization cylinder 201.

[0034] During use, fruit shells are fed into the feed hopper 202 and then into the carbonization cylinder 201 through the feed inlet 203. After feeding, the middle sealing plate 112, the lower sealing plate 317, and the upper sealing plate 321 seal the carbonization cylinder 201, while the feed sealing plate 310 seals the feed hopper 202. The heat in the combustion chamber 103 heats the carbonization cylinder 201, thus carbonizing the fruit shells inside. The turning motor 204 drives the motor gear 205 to rotate, which in turn drives the turning gear 207 and the carbonization cylinder 201 to rotate, ensuring that the fruit shells inside the carbonization cylinder 201 are heated evenly and improving the carbonization effect. The combustible gas produced by the carbonization of the fruit shells enters the burner 102 through the return gas pipe 206 for combustion and utilization, avoiding the direct emission of gas produced by the carbonization of the fruit shells and improving environmental protection.

[0035] After the fruit shells are carbonized, the lower sealing plate 317, the upper sealing plate 321 and the feed sealing plate 310 are opened, and the conveying gear 209 drives the conveying shaft 208 to rotate, and the carbonized fruit shells are conveyed to the activation room 107 for activation through the conveying shaft 208.

[0036] like Figures 8-10 As shown, the separating mechanism includes a switching motor 301 fixedly mounted on the furnace body 101. A half-tooth gear 302 is fixedly mounted on the motor shaft of the switching motor 301. An internal half-tooth gear 304 is rotatably mounted on the furnace body 101. An external gear 303 is fixedly mounted on the internal half-tooth gear 304. A bidirectional lead screw 305 is rotatably mounted on the furnace body 101. A lead screw gear 306 is fixedly mounted on the bidirectional lead screw 305. The half-tooth gear 302 meshes with the external gear 303. When the internal half-tooth gear 304 meshes with the conveying gear 209, the internal half-tooth gear 304 disengages from the lead screw gear 306. When the internal half-tooth gear 304 meshes with the lead screw gear 306, the internal half-tooth gear 304 disengages from the conveying gear 209.

[0037] like Figures 8-10 As shown, a sliding seat 307 is slidably installed on the furnace body 101. The sliding seat 307 and the bidirectional lead screw 305 form a threaded transmission. A push rod 309 is fixedly installed on the sliding seat 307. A feed sealing plate 310 is fixedly installed on the push rod 309. A sealing spring 311 is provided between the feed sealing plate 310 and the furnace body 101. A stand 312 is fixedly installed on the furnace body 101. Two lifting blocks 313 are slidably installed on the stand 312. An active rotating rod 308 is rotatably installed on the sliding seat 307. The active rotating rod 308 is rotatably installed with the lifting blocks 313. An upper rotating rod 314 is rotatably installed on the lifting blocks 313. A lower arc rod 315 is rotatably installed on the upper rotating rod 314. A sealing block 316 is slidably installed at the bottom of the furnace body 101. The sealing block 316 is rotatably installed with the two lower arc rods 315.

[0038] like Figures 8-10As shown, a lower sealing plate 317 is fixedly installed on the sealing block 316. The lower sealing plate 317 slides within the middle sealing plate 112. An upper sealing plate 321 is slidably installed within the middle sealing plate 112. A lower rack 318 is fixedly installed on the lower sealing plate 317. An upper rack 320 is fixedly installed on the upper sealing plate 321. Three sealing gears 319 are rotatably installed within the middle sealing plate 112. Adjacent sealing gears 319 mesh with each other. The lower rack 318 meshes with the sealing gear 319 located on the left, and the sealing gear 319 located on the right meshes with the upper rack 320. The upper sealing plate 321 and the lower sealing plate 317 are provided with semi-circular arcs to avoid the conveyor shaft 208.

[0039] The switching motor 301 drives the half-gear 302 to rotate, which in turn drives the internal half-gear 304 and the external gear 303 to rotate intermittently. When the internal half-gear 304 meshes with the conveying gear 209, it disengages from the lead screw gear 306. At this time, the push rod 309 drives the conveying gear 209 and the conveying shaft 208 to rotate. The feed sealing plate 310, the lower sealing plate 317, and the upper sealing plate 321 are in the open state. After the internal half-gear 304 disengages from the conveying gear 209, it begins to mesh with the lead screw gear 306. At this time, the carbonized fruit shells have been conveyed to the activation stage. In chamber 107, the next batch of fruit shells to be carbonized is placed into carbonization cylinder 201. At this time, the internal half-tooth gear 304 drives the lead screw gear 306 and the double-acting lead screw 305 to rotate. The double-acting lead screw 305 drives the sliding seat 307 to slide along the furnace body 101. The sliding seat 307 drives the push rod 309 and the feed sealing plate 310 to move towards the feed hopper 202. At the same time, the sliding seat 307 drives the lifting block 313 to rise along the upright frame 312 through the active rotating rod 308. It drives the sealing block 316 and the lower sealing plate 317 to rise through the upper rotating rod 314 and the lower arc rod 315. The lower sealing plate 317 drives the sealing gear 319 through the lower rack 318. As the gear rotates, the closed gear 319 drives the upper rack 320 and the upper closed plate 321 to descend, thereby achieving the simultaneous rise of the lower closed plate 317 and the fall of the upper closed plate 321. When the sliding seat 307 moves to the end of the double-acting screw 305, the half-tooth gear 302 disengages from the external gear 303, causing the internal half-tooth gear 304 to stop rotating. At this time, the feed sealing plate 310 closes the feed hopper 202, and the lower closed plate 317 and the upper closed plate 321 separate the activation chamber 107 from the carbonization cylinder 201. Carbonization takes place in the carbonization cylinder 201, and activation takes place in the activation chamber 107. When the half-tooth gear 302 meshes with the external gear 303 again... Then, the internal half-gear 304 drives the bidirectional lead screw 305 to rotate. Since the bidirectional lead screw 305 is provided with bidirectional external threads, the sliding seat 307 begins to move and reset in the direction of the lead screw gear 306. When the half-gear 302 disengages from the external gear 303 again, the sliding seat 307 returns to its initial position. At this time, the feed sealing plate 310, the lower sealing plate 317, and the upper sealing plate 321 are fully opened. When the half-gear 302 meshes with the external gear 303 again, the internal half-gear 304 begins to mesh with the conveying gear 209, conveying the carbonized fruit shells in the carbonization cylinder 201 to the activation chamber 107, and so on.

[0040] The working principle of the environmentally friendly fruit shell activated carbon activation furnace disclosed in this invention is as follows: the burner 102 supplies heat to the combustion chamber 103 and the combustion ring chamber 104. The heat in the combustion chamber 103 heats the carbonization cylinder 201, and the water in the hot water chamber 105 is heated and evaporated through the combustion ring chamber 104. During use, fruit shells are fed into the hopper 202 and enter the carbonization cylinder 201 through the feed inlet 203. After feeding is completed, the middle sealing plate 112, the lower sealing plate 317, and the upper sealing plate 321 seal the carbonization cylinder 201. Plate 310 seals the feed hopper 202, and heats the carbonization cylinder 201 through the heat in the combustion chamber 103, thereby carbonizing the fruit shells in the carbonization cylinder 201. The turning motor 204 drives the motor gear 205 to rotate, which in turn drives the turning gear 207 and the carbonization cylinder 201 to rotate, so that the fruit shells in the carbonization cylinder 201 can be heated evenly, improving the carbonization effect. The combustible gas produced by the carbonization of the fruit shells enters the burner 102 through the return gas pipe 206 for combustion and utilization, avoiding the direct emission of the gas produced by the carbonization of the fruit shells and improving environmental protection. Steam enters the steam chamber 109 through the steam trap 106. Steam enters the activation chamber 107 through the gap between the heating rod 108 and the activation chamber 107. The heating rod 108 heats the activation chamber 107 at high temperature. Steam acts as an activator and enters the activation chamber 107 to mix with the carbonized fruit shells in the activation chamber 107 and heat them together to activate the fruit shells. After activation, the fruit shells will slide along the inner wall of the activation chamber 107 to the sealing plate 110. Opening the sealing plate 110 allows the finished product to be taken out.

[0041] The switching motor 301 drives the half-gear 302 to rotate, which in turn drives the internal half-gear 304 and the external gear 303 to rotate intermittently. When the internal half-gear 304 meshes with the conveying gear 209, it disengages from the lead screw gear 306. At this time, the push rod 309 drives the conveying gear 209 and the conveying shaft 208 to rotate. The feed sealing plate 310, the lower sealing plate 317, and the upper sealing plate 321 are in the open state. After the internal half-gear 304 disengages from the conveying gear 209, it begins to mesh with the lead screw gear 306. At this time, the carbonized fruit shells have been conveyed to the activation stage. In chamber 107, the next batch of fruit shells to be carbonized is placed into carbonization cylinder 201. At this time, the internal half-tooth gear 304 drives the lead screw gear 306 and the double-acting lead screw 305 to rotate. The double-acting lead screw 305 drives the sliding seat 307 to slide along the furnace body 101. The sliding seat 307 drives the push rod 309 and the feed sealing plate 310 to move towards the feed hopper 202. At the same time, the sliding seat 307 drives the lifting block 313 to rise along the upright frame 312 through the active rotating rod 308. It drives the sealing block 316 and the lower sealing plate 317 to rise through the upper rotating rod 314 and the lower arc rod 315. The lower sealing plate 317 drives the sealing gear 319 through the lower rack 318. As the gear rotates, the closed gear 319 drives the upper rack 320 and the upper closed plate 321 to descend, thereby achieving the simultaneous rise of the lower closed plate 317 and the fall of the upper closed plate 321. When the sliding seat 307 moves to the end of the double-acting screw 305, the half-tooth gear 302 disengages from the external gear 303, causing the internal half-tooth gear 304 to stop rotating. At this time, the feed sealing plate 310 closes the feed hopper 202, and the lower closed plate 317 and the upper closed plate 321 separate the activation chamber 107 from the carbonization cylinder 201. Carbonization takes place in the carbonization cylinder 201, and activation takes place in the activation chamber 107. When the half-tooth gear 302 meshes with the external gear 303 again... Then, the internal half-gear 304 drives the bidirectional lead screw 305 to rotate. Since the bidirectional lead screw 305 is provided with bidirectional external threads, the sliding seat 307 begins to move and reset in the direction of the lead screw gear 306. When the half-gear 302 disengages from the external gear 303 again, the sliding seat 307 returns to its initial position. At this time, the feed sealing plate 310, the lower sealing plate 317, and the upper sealing plate 321 are fully opened. When the half-gear 302 meshes with the external gear 303 again, the internal half-gear 304 begins to mesh with the conveying gear 209, conveying the carbonized fruit shells in the carbonization cylinder 201 to the activation chamber 107, and so on.
