Abstract
Description
Technical Field
[0001] This utility model relates to the field of activated carbon production technology, and in particular to a special cooling device for an activation furnace in activated carbon production. Background Technology
[0002] In the activated carbon production process, the activation furnace is a key piece of equipment. Activated activated carbon reaches extremely high temperatures and requires cooling before subsequent storage, transportation, and processing. Therefore, the performance of the dedicated cooling device for the activation furnace directly affects the production efficiency, product quality, energy consumption, and production safety. Currently, existing activation furnace cooling devices have several problems. Regarding cooling efficiency, some devices use natural cooling or simple spray cooling, resulting in slow cooling rates that are difficult to meet the needs of large-scale continuous production. While some devices use pipeline cooling, the uneven distribution of activated carbon within the furnace and insufficient contact with the cooling medium lead to poor cooling effects. Furthermore, the cooled activated carbon remains at a high temperature, making it prone to reignition and posing a safety hazard. In addition, the high-temperature gases generated during the cooling process are often directly emitted, wasting heat energy and polluting the surrounding environment due to the dust and harmful substances contained in the gases. Announcement No. CN221093755U discloses an activation furnace for activated carbon production, relating to the field of activated carbon production technology. The furnace includes a furnace body, a feed pipe, a hopper, and an end cover. A motor is mounted on the upper surface of the furnace body near the end cover, and a drive gear is mounted on the output end of the motor. Fixed plates are symmetrically fixed to the inner wall of the top of the furnace body, and a lead screw is installed between the fixed plates. A driven gear is mounted on the end of the lead screw near the drive gear, and the drive gear and driven gear mesh. A threaded block is fitted onto the outer surface of the lead screw, and a scraper ring is mounted on the top of the threaded block. While this device facilitates material discharge, the heated activated carbon needs to be cooled before discharge, and natural cooling consumes a significant amount of time, requiring improvement.

[0006] Preferably, both ends of the slide rod are fixedly connected to the surface of the connecting block and the furnace body, respectively, while the surface of the pusher plate is slidably connected to the interior of the furnace body.

The fixing block 2 is tightly fixed to the surface of the furnace body 1 by bolts to ensure the stability of the motor A3 during operation. The bottom of the support ring 12 is welded with anti-slip pads, and three are evenly distributed around the circumference of the furnace body 1 to stably support the furnace body 1 and prevent shaking during operation.

[0026] Example 2
[0027] Please see Figure 1-3 , Figure 6-7 An air outlet pipe 14 is fixedly connected to the surface of the furnace body 1. A material box 15 is fixedly connected to one end of the air outlet pipe 14. A feed pipe 16 is fixedly connected to the bottom end of the material box 15. A cylinder 17 is fixedly connected to the upper surface of the material box 15. A baffle 18 is fixedly connected to the output end of the cylinder 17. A motor C19 is fixedly connected to the surface of the feed pipe 16. A rotating rod 20 is fixedly connected to the output end of the motor C19. A rotating plate 21 is fixedly connected to the surface of the rotating rod 20. A filter box 22 is fixedly connected to the upper surface of the material box 15. Here, the connection point between the air outlet pipe 14 and the furnace body 1 is close to the discharge cover 13. An inclined guide plate is installed inside the material box 15, facing the feed pipe 16 to facilitate the sliding of activated carbon. The cylinder 17 is fixed to the upper surface of the material box 15 by a bracket, and its piston rod is connected to the baffle 18 via a coupling, allowing precise control of the baffle 18's lifting height. The filter box 22 contains an activated carbon filter and a HEPA filter from top to bottom, effectively filtering harmful substances and dust from the exhaust gas to reduce pollution. The surface of the baffle 18 is slidably connected to the interior of the material box 15. Both ends of the rotating rod 20 are rotatably connected to the interior of the feed pipe 16. Filters are installed at both ends of the air outlet pipe 14. Here, a high-temperature resistant silicone strip is adhered to the surface of the baffle 18, providing a good seal when it slides in contact with the interior of the material box 15, preventing activated carbon from leaking out through gaps. A mechanical seal is installed at the rotatable connection between the rotating rod 20 and the feed pipe 16 to prevent activated carbon powder from entering and affecting rotation. The filters at both ends of the air outlet duct 14 are made of stainless steel, which can prevent activated carbon particles from being discharged with the airflow without affecting the gas flow.
[0028] Working Principle: During the activated carbon cooling stage, motor A3 is first started, driving gear A4 to rotate. Since gear A4 meshes with gear B6, gear B6 rotates accordingly, adjusting the opening and closing state of the fan-shaped groove inside connecting block 5 and gear B6. When cooling is required, the fan-shaped groove opens, facilitating the entry of activated carbon into furnace body 1. Simultaneously, fan 7 starts, supplying cold air into furnace body 1 through the air duct. Motor B8 drives screw 9 to rotate, and under the guidance of slide rod 11, pusher plate 10 reciprocates within furnace body 1, propelling the activated carbon within the furnace body 1. The lower semi-circular arc design of pusher plate 10 fits snugly against the inner wall of furnace body 1, and the vents on its surface allow cold air to fully contact the activated carbon, achieving rapid cooling. Air outlet duct 14 delivers the hot air discharged from furnace body 1 to material box 15, preheating the activated carbon raw material to be processed within material box 15. At this time, cylinder 17 controls baffle 18 to close, and motor C19 drives rotating rod 20 and rotating plate 21 to rotate, thus sealing feed pipe 16, reducing heat loss, and improving preheating effect. The preheated activated carbon enters subsequent processing stages through feed pipe 16, shortening processing time. The gas discharged after preheating enters filter box 22, passing through activated carbon filter and HEPA filter in sequence to remove dust and harmful substances before being discharged, meeting environmental protection requirements.
