Description

Technical Field

[0001] The present invention relates to the technical field of carbon powder, and particularly to an inerting treatment device for preventing spontaneous combustion of biochar. Background Art

[0002] Carbon powder is a high-risk product and is extremely prone to spontaneous combustion during storage, transportation and use. How to solve the problem of spontaneous combustion of carbon powder is a thorny issue in the carbon industry. At present, the industry mainly adopts the method of "sealed packaging" to isolate carbon powder from air through physical means, thereby avoiding spontaneous combustion of carbon powder. However, during actual storage and transportation, it is inevitable that the sealed bag is damaged, and the carbon powder will heat up after contacting with air and further develop into spontaneous combustion, thus causing major safety accidents.

[0003] At present, in the carbon industry, there is no better solution to the problem of spontaneous combustion of carbon powder caused by damaged sealed bags, and only the strategy of further thickening the sealed bag can be adopted. However, thickening the sealed bag means increasing the packaging cost and also cannot fundamentally solve the problem of spontaneous combustion of carbon powder. Therefore, we propose an inerting treatment device for preventing spontaneous combustion of biochar. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention provides an inerting treatment device for preventing spontaneous combustion of biochar, which solves the problems raised in the above background art.

[0005] To achieve the above objectives, the present invention is realized through the following technical solutions: An inerting treatment device for preventing the spontaneous combustion of biochar, comprising a bottom plate. A vertical frame and an H-shaped frame are fixed to the top of the bottom plate. The top of the vertical frame is fixed with a T-shaped feeding cylinder. The top of the T-shaped feeding cylinder is provided with a feeding port. A rotating rod is rotatably installed inside the T-shaped feeding cylinder and is driven by a motor. A spiral blade is fixed to the outside of the rotating rod. A fixed shell is embedded in the top of the T-shaped feeding cylinder. The top of the fixed shell penetrates and is fixed with an atomizing spray water pipe. An oxidant pipe is fixed to the side wall of the T-shaped feeding cylinder. A driving motor is fixed to the top of the horizontal support plate of the H-shaped frame. A rotary cylinder is rotatably installed at the top of the H-shaped frame. A belt ring is fixed to the outside of the rotary cylinder. The belt ring is connected to the output end of the driving motor through a belt. A sedimentation tank is fixedly installed on the top of the bottom plate through a bracket. An induced draft fan is fixed to the top of the sedimentation tank. A spiral discharge cylinder is fixed to the bottom of the sedimentation tank. A circular cover is fixedly installed on one side of the sedimentation tank close to the rotary cylinder through a bracket. The rotary cylinder is rotatably installed between the T-shaped feeding cylinder and the circular cover. A discharge pipe is fixed between the circular cover and the top of the sedimentation tank. A heating component and a refrigeration component are fixed to the middle of the top of the bottom plate. The top of the heating component is fixed with a hot water jacket through a pipe. The top of the refrigeration component is fixed with a cooling water jacket through a pipe. The hot water jacket and the cooling water jacket are respectively sleeved on both sides of the rotary cylinder. Connect the atomizing spray water pipe to an external water source and the oxidant pipe to an external gas source. Start the driving motor. The driving motor drives the belt ring to rotate through the belt. The belt ring drives the rotary cylinder to rotate. Put dry carbon powder into the T-shaped feeding cylinder through the feeding port of the T-shaped feeding cylinder. Drive the rotating rod to rotate through the motor. The rotating rod drives the spiral blade to rotate. The dry carbon powder enters the rotary cylinder through the spiral blade. And during this process, the atomizing spray water pipe can spray water and add it to the carbon powder while feeding. Through the rotation and stirring of the spiral blade and the rotary cylinder, the carbon powder is kept evenly moist, thus realizing "adding water and stirring of dry carbon powder". At the same time, start the heating component and the refrigeration component. The heating component heats the hot water jacket. Hot water at ℃~℃ is passed through the hot water jacket. Thus, the hot water jacket preheats the moist carbon powder near the entrance of the rotary cylinder, thus realizing "preheating and temperature rise". Spray the oxidant (gaseous) into the rotary cylinder. The refrigeration component cools the cooling water jacket. The cooling water jacket cools the moist carbon powder near the outlet of the rotary cylinder to room temperature. The inactivated carbon powder after cooling is discharged from the carbon outlet at the bottom of the sedimentation chamber, thus realizing "cooling and temperature reduction". The volatile organic compounds adsorbed in the carbon powder react with the oxidant through low-temperature oxidation, thus realizing "low-temperature oxidation". The carbon powder processed in the rotary cylinder enters the sedimentation tank through the discharge pipe. Start the induced draft fan. The induced draft fan draws out and discharges the water vapor and waste gas, thus realizing "induced draft discharge". Finally, the spiral discharge cylinder can be started to draw out the carbon powder from the rotary cylinder for packaging and warehousing.

[0006] According to the above technical solution, a trapezoidal column is fixed at one end of the rotating rod away from the spiral blade, and the trapezoidal column is located inside the rotary cylinder. A plurality of stirring plates are evenly fixed on the outer wall circumference of the trapezoidal column, and the stirring plates are in contact with the inner wall of the rotary cylinder. The inner wall of the rotary cylinder is arranged in an inclined shape, and the inclined shape of the rotary cylinder is parallel to the inclined surface of the trapezoidal column. The rotating rod drives the trapezoidal column to rotate, and the trapezoidal column drives the stirring plates to rotate, so that the stirring plates stir the wet carbon powder near the inlet of the rotary cylinder. At the same time, the trapezoidal column restricts the flow rate of the wet carbon powder during the preheating process to the outlet of the rotary cylinder.

[0007] According to the above technical solution, a shielding device is arranged at the trapezoidal column. The shielding device includes a flower groove plate and an L-shaped convex ball rod. The flower groove plate is fixed on the side of the trapezoidal column away from the T-shaped feeding cylinder. A plurality of grooves are formed in the outer wall of the flower groove plate. The inner wall of the groove of the flower groove plate is hinged with a shielding plate. A cavity is arranged inside the trapezoidal column. A Z-shaped rod is horizontally penetrated and slidably connected to the inner circumference of the cavity of the trapezoidal column, and a spring is arranged between the Z-shaped rod and the trapezoidal column. A semi-sphere is fixed on the side of the Z-shaped rod close to the T-shaped feeding cylinder. The side of the Z-shaped rod away from the T-shaped feeding cylinder is slidably connected to the outer wall of the shielding plate. The L-shaped convex ball rod is fixed at the eccentric position on the side of the T-shaped feeding cylinder close to the rotary cylinder. A convex ball is fixed at one end of the L-shaped convex ball rod away from the T-shaped feeding cylinder. The convex ball of the L-shaped convex ball rod is located on the movement track of the semi-sphere. The shielding plate will form a shield at the trapezoidal column. When the trapezoidal column rotates, it will drive the semi-sphere to rotate through the Z-shaped rod. When the semi-sphere rotates to the position of the convex ball of the L-shaped convex ball rod, the convex ball of the L-shaped convex ball rod pushes the semi-sphere to drive the Z-shaped rod to move towards the trapezoidal column. The Z-shaped rod pushes the shielding plate to swing away from the trapezoidal column. At this time, the shielding plate does not form a shield at the trapezoidal column, and the carbon powder can flow from the carbon powder to the outlet of the rotary cylinder. When the convex ball of the L-shaped convex ball rod no longer pushes the semi-sphere, the Z-shaped rod resets under the action of the corresponding spring force, and the Z-shaped rod drives the shielding plate to swing towards the trapezoidal column. At this time, the shielding plate re-forms a shield at the shielding plate.

[0008] According to the above technical solution, the shielding device also includes an elastic telescopic column, the fixed end of the elastic telescopic column is fixed to the inner wall of the cavity of the trapezoidal column away from the T-shaped feeding tube, the telescopic end of the elastic telescopic column is fixed with a fixed disk, and a plurality of elastic telescopic rods are evenly fixed on the circumference of the outer wall of the fixed disk, a sliding rod is fixed on the side of the elastic telescopic rod away from the fixed disk, and the sliding rod transversely penetrates the trapezoidal column, a sliding groove for accommodating the sliding rod is provided on the inner wall of the cavity of the trapezoidal column, and a plurality of trapezoidal shovel plates are evenly and equidistantly fixed on both sides of the side of the sliding rod away from the trapezoidal column, the vertical support plate of the Z-shaped rod is in contact with the outer wall of the fixed disk, and the side of the trapezoidal shovel plate close to the T-shaped feeding tube is an inclined surface The Z-shaped rod is set to move in the direction of the trapezoidal column, and the trapezoidal shovel plate contacts the outer wall of the sliding rod. During the movement of the Z-shaped rod in the direction of the trapezoidal column, the Z-shaped rod pushes the fixed plate to move along, and the fixed plate squeezes the telescopic end of the elastic telescopic column, and the fixed plate drives the sliding rod to move along through the elastic telescopic rod. When the Z-shaped rod is reset, the Z-shaped rod no longer pushes the fixed plate, and under the elastic force of the elastic telescopic column, the telescopic end of the elastic telescopic column pushes the fixed plate to reset and move, and the fixed plate drives the sliding rod to reset and move through the elastic telescopic rod. At the same time, when the trapezoidal shovel plate moves away from the trapezoidal column, the inclined surface of the trapezoidal shovel plate will scoop up the carbon powder, and when the trapezoidal shovel plate moves in the direction of the trapezoidal column, the vertical surface of the trapezoidal shovel plate will push the carbon powder to flow toward the trapezoidal column.

[0009] According to the above technical solution, a square groove is opened inside the rotating rod, a slide plate is slidably installed inside the square groove of the rotating rod, and a spring is provided between the slide plate and the inner wall of the square groove of the rotating rod, a plurality of top blocks are evenly and equidistantly fixed on the top of the slide plate, and the plurality of top blocks vertically penetrate the inner wall of the square groove of the rotating rod, a push block is fixed at the bottom of one end of the slide plate away from the T-shaped feeding cylinder, and the push block vertically penetrates the inner wall of the square groove of the rotating rod, a resist rod is fixed at the bottom of the L-shaped convex ball rod, and the push block is away from the slide plate. One end is semicircular, and the end of the resistance rod away from the L-shaped convex ball rod is semicircular. The semicircular shape of the resistance rod is located on the semicircular movement trajectory of the push block. When the rotating rod rotates, the push block is driven to rotate through the slide plate. When the semicircular shape of the push block rotates to the semicircular position of the resistance rod, the semicircular shape of the resistance rod pushes the semicircular shape of the push block to drive the slide plate to slide along the square groove of the rotating rod. When the semicircular shape of the resistance rod no longer pushes the semicircular shape of the push block, the slide plate is reset under the action of the corresponding spring force.

[0010] The present invention provides an inertization treatment device for preventing spontaneous combustion of biochar. It has the following beneficial effects: (1) The present invention adopts a process flow idea of ​​adding water for stirring, preheating, low-temperature oxidation, induced draft discharge, and cooling. This process can remove the active substances contained in the carbon powder, making the carbon powder inactive and thus in a stable state. The carbon powder treated by this process is exposed to the air and the natural temperature rise is generally less than 20°C, which fundamentally solves the technical problem of spontaneous combustion of carbon powder during storage, transportation and use. At the same time, the rotating rod and the trapezoidal column cooperate to drive the stirring plate to stir the wet carbon powder near the entrance of the rotating drum, so that the carbon powder is heated in the return drum. Uniform movement occurs in the rotating drum. This stirring effect helps to transfer the heat provided by the hot water jacket to the wet carbon powder more evenly, thereby avoiding the wet carbon powder staying motionless in a local area and causing uneven preheating. At the same time, the trapezoidal column limits the speed at which the wet carbon powder flows to the outlet of the rotating drum during the preheating process. By limiting the speed at which the wet carbon powder flows to the outlet of the rotating drum, the carbon powder stays in the inlet of the rotating drum longer, which allows the hot water jacket to exchange heat with the carbon powder for a longer time, thereby ensuring that the carbon powder can fully absorb heat.

[0011] (2) The present invention drives the baffle plate to intermittently form a shield at the trapezoidal column through the cooperation of the baffle plate, trapezoidal column, Z-shaped rod, semi-circular ball, and L-shaped convex ball rod. The baffle plate can reduce heat waste by blocking the transfer of heat to the outlet area of ​​the rotary drum, thereby ensuring that the heat energy of the hot water jacket is concentrated on the inlet area of ​​the rotary drum.

[0012] (3) The present invention drives the trapezoidal shovel plate to shovel back and forth on the surface of the stirring plate through the cooperation of the Z-shaped rod, the trapezoidal column, the fixed plate, and the elastic telescopic column. The wet carbon powder is easily adhered to the surface of the stirring plate due to the presence of water, resulting in a decrease in the stirring effect of the stirring plate. The trapezoidal shovel plate can effectively scrape off the carbon powder adhered to the surface by shoveling back and forth on the surface of the stirring plate, ensuring that the surface of the stirring plate remains clean and avoiding the accumulation of carbon powder, thereby ensuring the continuity and efficiency of the stirring process. At the same time, when the trapezoidal shovel plate moves away from the trapezoidal column, the inclined surface of the trapezoidal shovel plate will scoop up the carbon powder. When the trapezoidal shovel plate moves toward the trapezoidal column, the vertical surface of the trapezoidal shovel plate will push the carbon powder toward the trapezoidal column. The coordinated action of the inclined surface and the vertical surface of the trapezoidal shovel plate can effectively push the carbon powder and make it flow, which helps to avoid the carbon powder from agglomerating or being retained in the rotary drum due to moisture.

[0013] (4) The present invention uses the rotating rod, the sliding plate, the pushing block and the abutting rod to drive the top block to move the carbon powder in the T-shaped feeding barrel, so that the water sprayed by the atomizing water spray pipe can penetrate the surface of the carbon powder more evenly. This uniform water distribution can avoid excessive or insufficient water in certain areas. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0017] Please refer to Figure 1 - Figure 6, an embodiment of the present invention is: an inerting treatment device for preventing the spontaneous combustion of biochar, including a bottom plate 1. A vertical frame 12 and an H-shaped frame 11 are fixed on the top of the bottom plate 1. The top of the vertical frame 12 is fixed with a T-shaped feeding cylinder 14. The top of the T-shaped feeding cylinder 14 is provided with a feeding port. A rotating rod 141 is rotatably installed inside the T-shaped feeding cylinder 14, and the rotating rod 141 is driven by a motor. A spiral blade 142 is fixed on the outside of the rotating rod 141. A fixed shell 15 is embedded on the top of the T-shaped feeding cylinder 14. The top of the fixed shell 15 penetrates and is fixed with an atomizing spray water pipe 16. An oxidant pipe 17 is fixed at the side wall of the T-shaped feeding cylinder 14. A driving motor 13 is fixed on the top of the horizontal support plate of the H-shaped frame 11. A rotary cylinder 19 is rotatably installed on the top of the H-shaped frame 11. A belt ring 110 is fixed on the outside of the rotary cylinder 19. The belt ring 110 is connected to the output end of the driving motor 13 through a belt drive. A sedimentation tank 115 is fixedly installed on the top of the bottom plate 1 through a bracket. An induced draft fan 114 is fixed on the top of the sedimentation tank 115. A spiral discharge cylinder 116 is fixed at the bottom of the sedimentation tank 115. A round cover 112 is fixedly installed on one side of the sedimentation tank 115 close to the rotary cylinder 19 through a bracket. The rotary cylinder 19 is rotatably installed between the T-shaped feeding cylinder 14 and the round cover 112. A discharge pipe 113 is fixed between the round cover 112 and the top of the sedimentation tank 115. A heating component 118 and a refrigeration component 117 are fixed in the middle of the top of the bottom plate 1. A hot water jacket 18 is fixed on the top of the heating component 118 through a pipe. A cooling water jacket 111 is fixed on the top of the refrigeration component 117 through a pipe. The hot water jacket 18 and the cooling water jacket 111 are respectively sleeved on both sides of the rotary cylinder 19. Dry carbon powder enters the rotary cylinder 19 through the spiral blade 142. And in this process, the atomizing spray water pipe 16 can spray water into the carbon powder while feeding. Through the rotation and stirring of the spiral blade 142 and the rotary cylinder 19, the carbon powder is kept evenly moist, so as to realize "adding water and stirring of dry carbon powder". At the same time, the heating component 118 and the refrigeration component 117 are started. The heating component 118 heats the hot water jacket 18, and hot water at 50°C to 80°C is passed through the hot water jacket 18. Thus, the hot water jacket 18 preheats the moist carbon powder near the inlet of the rotary cylinder 19, so as to realize "preheating and temperature rising". The oxidant (gaseous state) is sprayed into the rotary cylinder 19. The refrigeration component 117 cools the cooling water jacket 111. The cooling water jacket 111 cools the moist carbon powder near the outlet of the rotary cylinder 19 to room temperature. The inactivated carbon powder after cooling is discharged from the carbon outlet at the bottom of the sedimentation chamber, so as to realize "cooling and temperature reduction". The volatile organic compounds adsorbed in the carbon powder carry out a low-temperature oxidation reaction with the oxidant, so as to realize "low-temperature oxidation". The carbon powder processed in the rotary cylinder 19 enters the sedimentation tank 115 through the discharge pipe 113. The induced draft fan 114 is started. The induced draft fan 114 draws out and discharges the water vapor and waste gas, so as to realize "induced draft discharge". By adopting the technological process idea of adding water and stirring, preheating and temperature rising, low-temperature oxidation, induced draft discharge, and cooling and temperature reduction, this process can remove the active substances contained in the carbon powder.The carbon powder is deactivated and thus in a stable state. After being processed by this technology, when the carbon powder is placed open to the air and naturally heated, the temperature generally rises less than 20°C, thus fundamentally solving the technical problem of spontaneous combustion of carbon powder during storage, transportation, and use.

[0018] One end of the rotating rod 141 away from the spiral blade 142 is fixed with a trapezoidal column 119, and the trapezoidal column 119 is located inside the rotary cylinder 19. A number of stirring plates 120 are evenly fixed on the outer wall circumference of the trapezoidal column 119. The stirring plates 120 are in contact with the inner wall of the rotary cylinder 19. The inner wall of the rotary cylinder 19 is inclined, and the inclination of the rotary cylinder 19 is parallel to the inclined surface of the trapezoidal column 119. Through the setting of the above structure, the stirring plates 120 stir the wet carbon powder near the entrance of the rotary cylinder 19, so that the carbon powder moves evenly in the rotary cylinder 19. This stirring effect helps to transfer the heat provided by the hot water jacket 18 more evenly to the wet carbon powder, thus avoiding the problem of uneven preheating caused by the wet carbon powder staying in a local area without moving. At the same time, the trapezoidal column 119 restricts the flow rate of the wet carbon powder during the preheating process to the outlet of the rotary cylinder 19. By restricting the flow rate of the wet carbon powder to the outlet of the rotary cylinder 19, the residence time of the carbon powder in the entrance of the rotary cylinder 19 becomes longer, which enables the hot water jacket 18 to exchange heat with the carbon powder for a longer time, thus ensuring that the carbon powder can fully absorb heat.

[0019] A shielding device 2 is arranged at the trapezoidal column 119. The shielding device 2 includes a fluted disc 21 and an L-shaped convex ball rod 25. The fluted disc 21 is fixed on the side of the trapezoidal column 119 away from the T-shaped feeding cylinder 14. A number of grooves are formed on the outer wall of the fluted disc 21. The inner wall of the groove of the fluted disc 21 is hinged with a shielding plate 22. A cavity is arranged inside the trapezoidal column 119. A Z-shaped rod 23 is evenly horizontally penetrated and slidably connected to the inner circumference of the cavity of the trapezoidal column 119, and a spring is arranged between the Z-shaped rod 23 and the trapezoidal column 119. A semi-sphere 24 is fixed on the side of the Z-shaped rod 23 close to the T-shaped feeding cylinder 14. The side of the Z-shaped rod 23 away from the T-shaped feeding cylinder 14 is slidably connected to the outer wall of the shielding plate 22. The L-shaped convex ball rod 25 is fixed at an eccentric position on the side of the T-shaped feeding cylinder 14 close to the rotary cylinder 19. A convex ball is fixed at the end of the L-shaped convex ball rod 25 away from the T-shaped feeding cylinder 14. The convex ball of the L-shaped convex ball rod 25 is located on the movement track of the semi-sphere 24. Through the setting of the above structure, the shielding plate 22 intermittently forms a shield at the trapezoidal column 119. By blocking the transfer of heat to the outlet area of the rotary cylinder 19, the shielding plate 22 can reduce heat waste, thus ensuring that the thermal energy of the hot water jacket 18 is concentrated on the entrance area of the rotary cylinder 19.

[0020] The shielding device 2 further includes an elastic telescopic column 26. The fixed end of the elastic telescopic column 26 is fixed to the inner wall of the cavity of the trapezoidal column 119 on the side away from the T-shaped feeding cylinder 14. A fixed disk 27 is fixed to the telescopic end of the elastic telescopic column 26. A plurality of elastic telescopic rods 28 are evenly fixed to the outer circumference of the outer wall of the fixed disk 27. A sliding rod 29 is fixed to the side of the elastic telescopic rod 28 away from the fixed disk 27, and the sliding rod 29 horizontally penetrates through the trapezoidal column 119. A sliding groove for accommodating the sliding rod 29 is formed in the inner wall of the cavity of the trapezoidal column 119. A plurality of trapezoidal shovel plates 210 are evenly fixed at equal intervals on both sides of the sliding rod 29 away from the trapezoidal column 119. The vertical plate of the Z-shaped rod 23 is in contact with the outer wall of the fixed disk 27. The side of the trapezoidal shovel plate 210 close to the T-shaped feeding cylinder 14 is provided with an inclined surface, and the trapezoidal shovel plate 210 is in contact with the outer wall of the sliding rod 29. Through the above structure, the sliding rod 29 drives the trapezoidal shovel plate 210 to shovel the surface of the stirring plate 120 back and forth. Due to the presence of moisture, the wet carbon powder is likely to adhere to the surface of the stirring plate 120, resulting in a decrease in the stirring effect of the stirring plate 120. The trapezoidal shovel plate 210 can effectively scrape off the carbon powder adhering to the surface by shoveling the surface of the stirring plate 120 back and forth, ensuring that the surface of the stirring plate 120 remains clean and avoiding carbon powder accumulation, thereby ensuring the continuity and high efficiency of the stirring process. At the same time, when the trapezoidal shovel plate 210 moves away from the trapezoidal column 119, the inclined surface of the trapezoidal shovel plate 210 will shovel up the carbon powder. When the trapezoidal shovel plate 210 moves towards the trapezoidal column 119, the vertical surface of the trapezoidal shovel plate 210 will push the carbon powder towards the trapezoidal column 119. The coordinated movement of the inclined surface and the vertical surface of the trapezoidal shovel plate 210 can effectively push the carbon powder and make it flow, which helps to avoid caking or retention of the carbon powder due to wetness in the rotary cylinder 19.

[0021] In use, connect the atomizing spray water pipe 16 to an external water source and the oxidant pipe 17 to an external gas source. Start the drive motor 13. The drive motor 13 drives the belt loop 110 to rotate through a belt. The belt loop 110 drives the rotary cylinder 19 to rotate. Feed dry carbon powder into the T-shaped feeding cylinder 14 through the feeding port of the T-shaped feeding cylinder 14. Drive the rotating rod 141 to rotate through a motor. The rotating rod 141 drives the spiral blade 142 to rotate. The dry carbon powder enters the rotary cylinder 19 through the spiral blade 142. And during this process, the atomizing spray water pipe 16 can spray water into the carbon powder while feeding. Through the rotation and stirring of the spiral blade 142 and the rotary cylinder 19, the carbon powder is kept evenly moist, thus realizing "adding water and stirring dry carbon powder". At the same time, start the heating component 118 and the refrigeration component 117. The heating component 118 heats the hot water jacket 18. Hot water at 50°C to 80°C is passed through the hot water jacket 18. Thus, the hot water jacket 18 preheats the moist carbon powder near the inlet of the rotary cylinder 19, thus realizing "preheating and temperature rise". Spray the oxidant (gaseous) into the rotary cylinder 19. The refrigeration component 117 cools the cooling water jacket 111. The cooling water jacket 111 cools the moist carbon powder near the outlet of the rotary cylinder 19 to room temperature. The inactivated carbon powder after cooling is discharged from the carbon powder outlet at the bottom of the sedimentation chamber, thus realizing "cooling down". The volatile organic compounds adsorbed in the carbon powder react with the oxidant through low-temperature oxidation, thus realizing "low-temperature oxidation". The carbon powder processed in the rotary cylinder 19 enters the sedimentation tank 115 through the discharge pipe 113. Start the induced draft fan 114. The induced draft fan 114 draws out and discharges the water vapor and waste gas, thus realizing "induced draft discharge". Finally, the spiral discharge cylinder 116 can be started to draw out the carbon powder from the rotary cylinder 19 for packaging and warehousing.

[0022] It should be noted that for adding water and stirring, add 2% - 5% of the weight of the carbon powder in the dry carbon powder as water, and use a rotary kiln for stirring to keep the carbon powder evenly moist. The purpose of adding 2% - 5% of water is mainly as follows: A humid environment is conducive to the low-temperature oxidation reaction of volatile organic compounds; the endothermic vaporization of water vapor can ensure that the environmental temperature is lower than 100°C to avoid the carbon powder being ignited; for preheating and temperature rise, in the space of the rotary kiln, heat the carbon powder through external circulating hot water to preheat the moist carbon powder to 50°C - 80°C; for low-temperature oxidation, introduce oxygen or air as an oxidant into the space of the rotary kiln (the addition amount of air is controlled at 0.5 - 1 standard cubic meter per kilogram of carbon powder, and oxygen is converted according to the oxygen content in the air). Use the rotation of the rotary kiln to make the moist carbon powder fully contact with the oxidant. The volatile organic compounds adsorbed in the carbon powder react with the gaseous oxidant through low-temperature oxidation, exhausting the active substances in the carbon powder and making the carbon powder lose its activity.

[0023] When the rotating rod 141 rotates, the rotating rod 141 drives the trapezoidal column 119 to rotate, and the trapezoidal column 119 drives the stirring plate 120 to rotate, so that the stirring plate 120 stirs the wet carbon powder near the inlet of the rotary cylinder 19, so that the carbon powder moves evenly in the rotary cylinder 19. This stirring effect helps to transfer the heat provided by the hot water jacket 18 more evenly to the wet carbon powder, thus avoiding the problem that the wet carbon powder stays in a local area without moving, resulting in uneven preheating. At the same time, the trapezoidal column 119 restricts the flow rate of the wet carbon powder during the preheating process to the outlet of the rotary cylinder 19. By restricting the flow rate of the wet carbon powder to the outlet of the rotary cylinder 19, the residence time of the carbon powder in the inlet of the rotary cylinder 19 becomes longer, which enables the hot water jacket 18 to exchange heat with the carbon powder for a longer time, so as to ensure that the carbon powder can fully absorb heat. It should be noted that the rotating direction of the rotating rod 141 is opposite to that of the rotary cylinder 19.

[0024] At the same time, the baffle plate 22 will form an obstruction at the trapezoidal column 119. When the trapezoidal column 119 rotates, it will drive the semi-sphere 24 to rotate through the Z-shaped rod 23. When the semi-sphere 24 rotates to the convex sphere position of the L-shaped convex sphere rod 25, the convex sphere of the L-shaped convex sphere rod 25 pushes the semi-sphere 24 to drive the Z-shaped rod 23 to move towards the trapezoidal column 119. The Z-shaped rod 23 pushes the baffle plate 22 to swing away from the trapezoidal column 119. At this time, the baffle plate 22 does not form an obstruction at the trapezoidal column 119, and the carbon powder can flow from the carbon powder to the outlet of the rotary cylinder 19. When the convex sphere of the L-shaped convex sphere rod 25 no longer pushes the semi-sphere 24, the Z-shaped rod 23 resets under the action of the corresponding spring force, and the Z-shaped rod 23 drives the baffle plate 22 to swing towards the trapezoidal column 119. At this time, the baffle plate 22 re-forms an obstruction at the baffle plate 22. In this way, the baffle plate 22 intermittently forms an obstruction at the trapezoidal column 119. By blocking the transfer of heat to the outlet area of the rotary cylinder 19, the baffle plate 22 can reduce heat waste, so as to ensure that the thermal energy of the hot water jacket 18 is concentrated on the inlet area of the rotary cylinder 19.

[0025] During the movement of the Z-shaped rod 23 towards the trapezoidal column 119, the Z-shaped rod 23 pushes the fixed disk 27 to move along, the fixed disk 27 squeezes the telescopic end of the elastic telescopic column 26, and the fixed disk 27 drives the sliding rod 29 to move along through the elastic telescopic rod 28. When the Z-shaped rod 23 resets, the Z-shaped rod 23 no longer pushes the fixed disk 27. Under the elastic force of the elastic telescopic column 26, the telescopic end of the elastic telescopic column 26 pushes the fixed disk 27 to move back, and the fixed disk 27 drives the sliding rod 29 to move back through the elastic telescopic rod 28. This reciprocating motion causes the sliding rod 29 to drive the trapezoidal shovel plate 210 to shovel back and forth on the surface of the stirring plate 120. Due to the presence of moisture, the wet carbon powder is likely to adhere to the surface of the stirring plate 120, resulting in a decrease in the stirring effect of the stirring plate 120. By shoveling back and forth on the surface of the stirring plate 120, the trapezoidal shovel plate 210 can effectively scrape off the carbon powder adhering to the surface, ensuring that the surface of the stirring plate 120 remains clean, avoiding carbon powder accumulation, and thus guaranteeing the continuity and efficiency of the stirring process. At the same time, when the trapezoidal shovel plate 210 moves away from the trapezoidal column 119, the inclined surface of the trapezoidal shovel plate 210 will shovel up the carbon powder, and when the trapezoidal shovel plate 210 moves towards the trapezoidal column 119, the vertical surface of the trapezoidal shovel plate 210 will push the carbon powder towards the trapezoidal column 119. The coordinated actions of the inclined surface and the vertical surface of the trapezoidal shovel plate 210 can effectively push the carbon powder and make it flow, which helps to prevent the carbon powder from caking or staying due to moisture in the rotary drum 19.

[0026] Please refer to Figure 1 - Figure 6 On the basis of the above embodiments, in another embodiment of the present invention, a square groove is formed inside the rotating rod 141. A sliding plate 145 is slidably installed inside the square groove of the rotating rod 141, and a spring is provided between the sliding plate 145 and the inner wall of the square groove of the rotating rod 141. A plurality of top blocks 146 are evenly and equidistantly fixed on the top of the sliding plate 145, and the plurality of top blocks 146 vertically penetrate the inner wall of the square groove of the rotating rod 141. A push block 144 is fixed to the bottom of the end of the sliding plate 145 away from the T-shaped feeding cylinder 14, and the push block 144 vertically penetrates the inner wall of the square groove of the rotating rod 141. A resisting rod 143 is fixed to the bottom of the L-shaped convex ball rod 25. The end of the push block 144 away from the sliding plate 145 is semicircularly arranged, and the end of the resisting rod 143 away from the L-shaped convex ball rod 25 is semicircularly arranged. The semicircular shape of the resisting rod 143 is located on the movement track of the semicircular shape of the push block 144. Through the above structural arrangement, the sliding plate 145 drives the top blocks 146 to stir the carbon powder in the T-shaped feeding cylinder 14, so that the water sprayed by the atomizing water spray pipe 16 can penetrate more evenly onto the surface of the carbon powder. This uniform water distribution can prevent some areas from having too much or too little water.

[0027] When in use, when the rotating rod 141 rotates, the push block 144 will be driven to rotate through the slide plate 145. When the semicircular shape of the push block 144 rotates to the semicircular position of the abutting rod 143, the semicircular shape of the abutting rod 143 pushes the semicircular shape of the push block 144 to drive the slide plate 145 to slide along the square groove of the rotating rod 141. When the semicircular shape of the abutting rod 143 no longer pushes the semicircular shape of the push block 144, the slide plate 145 is reset under the action of the corresponding spring force, and so on. As a result, the slide plate 145 drives the top block 146 to move the carbon powder in the T-shaped feeding barrel 14, so that the water sprayed by the atomizing water spray pipe 16 can penetrate into the surface of the carbon powder more evenly. This uniform moisture distribution can avoid excessive or insufficient moisture in certain areas.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
