Description

Technical Field

[0001] This invention relates to the field of activation stirring, specifically to an anti-caking stirring structure for an activated carbon steam activation furnace. Background Technology

[0002] The anti-caking stirring structure of the activated carbon steam activation furnace is a set of high-temperature resistant rotary stirring devices installed inside the furnace. The rotating shaft drives the stirring rake blades to continuously turn and scrape the carbon material, breaking up the carbon material that is prone to sticking and caking at high temperatures. It can also be used to evenly introduce activation steam to prevent the material from accumulating and clumping, leaving dead corners, and allowing the carbon material and steam to fully mix and react, ensuring uniform activation and smooth furnace operation. Existing activated carbon steam activation furnaces typically employ fixed-speed stirring structures, making it impossible to adjust the stirring rate as needed. High-temperature carbon materials are prone to breakage due to excessively fast stirring and agglomeration due to excessively slow stirring, resulting in poor adaptability and difficulty in matching different material activation processes, thus limiting production applicability. Furthermore, existing activated carbon steam activation furnaces often have fixed-spacing scrapers, which cannot adaptively adjust the spacing based on the thickness of material accumulation and the size of agglomerates within the furnace. This easily leads to incomplete scraping, residual material accumulation and agglomeration, and dead zones in the scraping process, severely affecting the uniformity of the activation reaction. Moreover, the existing activated carbon steam activation furnace stirring structures operate in high-temperature, dusty environments for extended periods, causing carbon materials to easily adhere to the stirring rollers and connecting parts, solidifying and agglomerating. These agglomerates cannot be removed by simply turning them over, easily leading to material accumulation, increased stirring resistance, and affecting material flow and activation efficiency within the furnace.

[0018] Example 1:

[0019] Please see Figures 1-3 The present invention provides an anti-caking stirring structure for an activated carbon steam activation furnace, comprising a steam activation furnace body 1, a stirring mechanism 2 fixedly connected to the top center of the steam activation furnace body 1, and a connecting pipe 3 fixedly connected to the top rear end of the steam activation furnace body 1.

[0020] The stirring mechanism 2 includes a first mounting box 21. The first mounting box 21 is installed at the center of the top of the steam activation furnace body 1, providing a closed mounting space for all internal components. A mounting base 22 is installed on the left side of the bottom of the first mounting box 21, providing stable support for the first motor 23. The first motor 23 is mounted on the left end of the mounting base 22, providing the rotational power source for the entire stirring mechanism 2. A grooved wheel 24 is mounted on the right output shaft of the first motor 23, which cooperates with a spherical disc 25 to achieve intermittent transmission. The grooved wheel 24 is fitted with the spherical disc 25, and the intermittent cooperation with the grooved wheel 24 drives the lower components to rotate intermittently. A stirring rod 26 is fixed at the center of the bottom of the spherical disc 25, used to agitate the carbon material inside the steam activation furnace body 1 and simultaneously drive the scraping mechanism 27 and the tapping mechanism 28 to operate. A scraping mechanism 27 is installed below the front end of the stirring rod 26. The stirring roller 26 is responsible for scraping off the carbon material adhering to the inner wall of the steam activation furnace body 1 to prevent caking. The bottom of the stirring roller 26 is equipped with a striking mechanism 28, which shakes off the solidified carbon material caking by vibration. A friction block 29 is fitted on the upper part of the outer wall of the stirring roller 26. The rotation speed of the stirring roller 26 is controlled by adjusting the rotational resistance. A second rotary encoder 210 is also fitted on the upper part of the outer wall of the stirring roller 26 to collect the rotational speed data of the stirring roller 26 in real time. The grooved wheel 24 and the mounting base 22 are rotatably connected to ensure that the grooved wheel 24 is stable and does not shift when it is running. A fixed seat is provided on the right side of the bottom of the first mounting box 21 to support the spherical disk 25 and ensure its smooth rotation. The second rotary encoder 210 is electrically connected to an external display screen to facilitate the staff to view the rotational speed parameters in real time. The second rotary encoder 210 is arranged below the friction block 29, which saves internal installation space through reasonable layout.

[0021] The working principle of the anti-caking stirring structure of the activated carbon steam activation furnace based on Example 1 is as follows: First, when using this device, place it in the work area, and then connect it to an external power source to provide the power required for its operation. Secondly, when stirring is required, the first motor 23 is started, which drives the grooved wheel 24 to rotate synchronously. Through the intermittent cooperation between the grooved wheel 24 and the spherical disk 25, the spherical disk 25 is driven to rotate intermittently, which in turn drives the stirring roller 26 to rotate intermittently. During the rotation of the stirring roller 26, the rotational resistance of the stirring roller 26 is adjusted by the friction block 29 to adjust the stirring speed. At the same time, the second rotary encoder 210 collects the speed data of the stirring roller 26 in real time and transmits it to the external display screen, so that the staff can observe and control it in real time. When the stirring roller 26 rotates, it synchronously drives the scraping mechanism 27 and the tapping mechanism 28 to rotate, so as to turn the carbon material in the furnace to prevent agglomeration.

[0022] Example 2:

[0023] Please see Figure 4The present invention discloses an anti-caking stirring structure for an activated carbon steam activation furnace. Compared with Embodiment 1, this embodiment further includes a scraping mechanism 27. The scraping mechanism 27 includes a second mounting box 271. The second mounting box 271 is fixed below the front end of the stirring roller 26, serving as a closed mounting shell for all parts of the scraping mechanism 27. A second motor 272 is installed at the rear end of the second mounting box 271 to provide power for adjusting the spacing of the scraper 278. A gear 273 is mounted on the front output shaft of the second motor 272, which drives the upper and lower toothed plates 276 to move synchronously through meshing transmission. A gear rod 274 is fixed at the front end of the gear 273 to support the gear 273 and simultaneously cooperates with the installation of a first rotary encoder 275. The first rotary encoder 275 is sleeved on the outer wall of the gear rod 274 to collect the rotation data of the gear rod 274 in real time and transmit it outward. The gear 273 meshes with the toothed plates 276 at both the upper and lower positions, relying on the gear 273 to drive the phase... The toothed plate 276 slides in opposite directions to adjust the spacing. A connecting rod 277 is connected to the outside of the toothed plate 276 to transmit the power of the toothed plate 276 to the scraper 278. The scraper 278 is fixed to the other end of the connecting rod 277 and slides against the inner wall of the steam activation furnace body 1 to scrape off the material on the wall and eliminate clumps and dead corners. The first rotary encoder 275 is electrically connected to an external display screen to facilitate real-time control of the working status of the scraper 278 by the operator. The scraper 278 slides against the inner wall of the steam activation furnace body 1 to fully clean the accumulated material according to the contour of the steam activation furnace body 1. The front end of the toothed plate 276 is slidably connected to the front end of the second mounting box 271 to restrict the toothed plate 276 to slide smoothly. The outer wall of the connecting rod 277 slides against the second mounting box 271 to ensure that the connecting rod 277 moves smoothly without jamming. The front end of the gear rod 274 is rotatably connected to the front end of the second mounting box 271 to allow the gear rod 274 to rotate stably and freely.

[0024] In this embodiment: When scraping is required, the second motor 272 is started. The second motor 272 drives the gear 273 and gear rod 274 to rotate. The gear 273 meshes with the two sets of toothed plates 276, causing the two sets of toothed plates 276 to move in opposite directions or away from each other inside the second mounting box 271. This causes the distance between the two sets of toothed plates 276 to gradually shorten or increase. Then, the two sets of toothed plates 276 drive the two sets of scrapers 278 to move synchronously through the two sets of connecting rods 277, changing the distance between the two sets of scrapers 278 to adapt to material layers of different thicknesses and lumps of different sizes in the furnace. The rotation data of the gear rod 274 is collected in real time by the first rotary encoder 275 and transmitted to the external display screen. When the scraper 278 slides against the inner wall of the steam activation furnace body 1, it scrapes off the carbon material attached to the furnace wall in all directions, eliminating scraping dead corners and preventing material accumulation and lumps.

[0025] Example 3:

[0026] Please see Figures 5-6The present invention discloses an anti-caking stirring structure for an activated carbon steam activation furnace. Compared with Embodiment 1, this embodiment further includes a striking mechanism 28. The striking mechanism 28 includes a third mounting box 281. The bottom of the stirring rod 26 is fixed to the third mounting box 281, which serves as a protective and mounting carrier for all components of the striking mechanism 28. A sliding groove 282 is provided on the lower back of the third mounting box 281 to provide a limited sliding trajectory for the moving block 284. Sixteen sets of electromagnetic blocks 283 are fixed inside the sliding groove 282. The alternating power outages generate magnetism, attracting and driving the movable block 284 to slide. The electromagnetic block 283 is equipped with the movable block 284, which slides back and forth within the groove 282 using electromagnetic attraction. A protruding rod 285 is fixed to the front end of the movable block 284. The movement of the movable block 284 drives the groove block 286 to form a lever action. The groove block 286 is slidably fitted onto the outer wall of the protruding rod 285, cooperating with the sliding of the protruding rod 285 to achieve lever swing transmission. A connecting seat 287 is connected to the left end of the groove block 286 to fix the fulcrum, allowing the groove block 286 to move. 6. It can swing stably. The connecting seat 287 is fixed inside the left end of the third mounting box 281, which serves to fix the fulcrum of the support lever. The top of the moving block 284 is fixed with a striking rod 288, which moves back and forth with the moving block 284 to realize the striking vibration inside the third mounting box 281. The outer wall of the striking rod 288 is fitted with a spring 289, which returns to its original position by its own elasticity and assists the striking rod 288 in reciprocating striking. The two ends of the spring 289 are fixed inside the mounting shell 2810 to limit the position of the spring 289. It provides a fixed support, and the back of the mounting shell 2810 is fixed to the rear end of the third mounting box 281, providing a mounting cavity for the spring 289 and the striking rod 288. The bottom of the third mounting box 281 is rotatably connected to the bottom of the steam activation furnace body 1, and rotates smoothly as a whole with the stirring rod 26. The electromagnetic block 283 is electrically connected to the external current output device to control the regular on and off of the electromagnetic block 283. The moving block 284 slides with the slide groove 282 to ensure that the moving block 284 can only slide smoothly along the predetermined track.

[0027] In this embodiment: When a striking action is required, the sixteen sets of electromagnetic blocks 283 are sequentially switched on and off via an external current output device, causing the electromagnetic blocks 283 in the slide 282 to alternately generate magnetism and demagnetize. Through magnetic attraction, the moving block 284 is driven to slide up and down inside the slide 282. When the moving block 284 moves, it drives the protruding rod 285 to slide inside the slide block 286, forming a lever swing in conjunction with the connecting seat 287. At the same time, the moving block 284 drives the striking rod 288 to slide up and down, compressing and stretching the spring 289. The elastic reset of the spring 289, combined with the reciprocating motion of the moving block 284, causes the striking rod 288 to reciprocate to strike the top of the interior of the third mounting box 281. The vibration shakes off the solidified carbon material clumps attached to the surface of the stirring mechanism 2 and inside the steam activation furnace body 1, preventing material adhesion and accumulation, and reducing the resistance of the stirring operation.

[0028] This invention provides an improved anti-caking stirring structure for an activated carbon steam activation furnace. It includes a stirring mechanism 2, which, through a first motor 23, a grooved wheel 24, an intermittent transmission structure with a spherical disc 25, a friction block 29, and a second rotary encoder 210, enables the stirring roller 26 to rotate intermittently with adjustable speed, adapting to different activated carbon conditions and preventing carbon particle breakage and agglomeration. A scraping mechanism 27, through a second motor 272, a gear 273, a toothed plate 276, a first rotary encoder 275, and a scraper 278, allows for adaptive adjustment of the scraper 278 spacing, ensuring comprehensive scraping against the furnace wall, eliminating dead-angle accumulation, and effectively preventing carbon material buildup and agglomeration. A striking mechanism 28, through an electromagnetic block 283, a moving block 284, a spring 289, and a striking rod 288, reciprocates and vibrates the material, shaking off solidified carbon blocks from components and the furnace wall, reducing adhesion and accumulation, and lowering the stirring load.
