Abstract
Description
Technical Field
[0001] This utility model relates to the field of activation furnace technology, and in particular to an activation furnace for porous carbon production. Background Technology
[0002] Activated carbon is a porous carbonaceous material with a very high specific surface area, widely used in water treatment, air purification, industrial decolorization, pharmaceuticals, and food processing. The production of activated carbon mainly includes key steps such as raw material selection, carbonization, and activation.
[0003] During production, the activation furnace needs to rotate continuously to ensure that the material is heated evenly during the high-temperature activation process. Most existing technologies use annular toothed plates on the outer wall of the activation furnace, which, together with gears, drive the furnace to rotate. However, the annular toothed plates are exposed to high temperatures, dust, and corrosive atmospheres for a long time. The high-temperature environment increases the friction between the metal surface of the annular toothed plates and the gears, which exacerbates mechanical wear and may even lead to jamming and tooth breakage in severe cases. Therefore, it is necessary to propose an activation furnace for porous carbon production to address the above problems. Utility Model Content
[0004] (a) Technical problems to be solved
[0005] To address the shortcomings of existing technologies, a piston-driven lubricant is automatically delivered from an external container to a spray plate via a connecting pipe. The lubricant is then evenly sprayed onto the meshing area between the gear and the ring gear plate, thus avoiding the problem of increased friction between the metal surface and the gear due to high temperatures on the surface of the ring gear plate.

Device cylinders are fixedly connected to the outer walls of both sets of fixing brackets. Two sets of connecting pipes are provided on the outer wall of the device cylinder. One set of connecting pipes is connected to a spray plate, which is located directly above its adjacent annular toothed plate. A piston is slidably connected inside the device cylinder.

[0013] (III) Beneficial Effects
[0014] Compared with the prior art, this utility model provides an activation furnace for porous carbon production, which has the following beneficial effects:
[0015] 1. This utility model uses a piston to push lubricant from an external container through a connecting pipe to an spray plate, and then sprays it evenly on the meshing area between the gear and the ring tooth plate. This ensures that the contact parts of the gear and tooth plate are always lubricated in high temperature and dusty environments, reducing wear caused by increased friction, thereby slowing down the friction between the ring tooth plate and the gear, reducing mechanical wear, and reducing the risk of jamming and tooth breakage.
[0016] 2. By setting up a limiting ring and a limiting wheel, this utility model ensures that the furnace body remains stable during rotation, effectively reducing vibration during operation, reducing mechanical burden, and extending the service life of the furnace body and other key components.

[0022] This utility model provides a technical solution for an activation furnace used in porous carbon production:
[0023] An activation furnace for porous carbon production includes a bottom plate 1 and a furnace body 2. Two sets of fixed brackets 3 are fixedly connected to the upper end of the bottom plate 1. The furnace body 2 is rotatably connected to the two sets of fixed brackets 3. Annular toothed plates 4 are fixedly connected to both ends of the furnace body 2. Two sets of side plates are fixedly connected to the end face of the bottom plate 1. Gears 5 are rotatably connected to the outer walls of the two sets of side plates. The gears 5 mesh with the annular toothed plates 4. Device cylinders 10 are fixedly connected to the outer walls of the two sets of fixed brackets 3. Two sets of connecting pipes 11 are provided on the outer walls of the device cylinders 10. One set of connecting pipes 11 is connected to a spray plate 9, which is located directly above its adjacent annular toothed plate 4. A piston 13 is slidably connected inside the device cylinder 10. A drive assembly for driving the piston 13 to slide is installed inside the device cylinder 10. One-way valves are installed in both sets of connecting pipes 11.
[0024] Specifically, through the cooperation of piston 13 and spray plate 9, lubricant is sprayed evenly to ensure the lubrication effect of the meshing area between the tooth plate and gear 5, and reduce friction and wear. It should be noted that during lubrication, another connecting pipe 11 can be connected to an external container containing lubricant, so that external lubricant can be automatically drawn into the device cylinder 10 for subsequent use.
[0025] The drive assembly includes a reciprocating screw 12 rotatably connected inside the device cylinder 10. A screw sleeve 14 is threadedly connected to the threaded section of the reciprocating screw 12. Two sets of connecting rods 15 are fixedly connected to the outer wall of the screw sleeve 14, and the ends are fixedly connected to the piston 13.
[0026] Specifically, the cooperation between the reciprocating screw 12 and the screw sleeve 14 enables the reciprocating motion of the piston 13, ensuring that the lubricant can be delivered evenly and continuously to the spray plate 9.
[0027] Two sets of limiting rings 7 are fixedly connected to the outer wall of the furnace body 2, and multiple sets of limiting wheels 8 are fixedly connected inside the two sets of fixing frames 3. The multiple sets of limiting wheels 8 slide on the outer wall of the limiting rings 7.
[0028] Specifically, the cooperation between the limiting ring 7 and the limiting wheel 8 ensures the stability of the furnace body 2's rotation and prevents the furnace body 2 from shifting or vibrating during rotation.
[0029] The reciprocating screw 12 is coaxially and fixedly connected to its adjacent limiting wheel 8. The outer walls on both sides of the screw sleeve 14 are in close contact with the inner wall of the device cylinder 10. The end of the reciprocating screw 12 is fixedly connected to a limiting block 16, and the radius of the limiting block 16 is larger than the radius of the reciprocating screw 12.
[0030] Specifically, the design of the limit block 16 prevents the lead screw sleeve 14 from disengaging from the reciprocating lead screw 12 during movement, ensuring that it can be effectively limited during movement.
[0031] A servo motor 6 is fixedly connected to the outer wall of the side plate, and the end of the output shaft of the servo motor 6 is coaxially fixedly connected to the adjacent gear 5.
[0032] In practical use, the working principle of this utility model is as follows:
[0033] First, the servo motor 6 is started, which drives the gear 5 to rotate. Through the meshing between the gear 5 and the ring toothed plate 4, the furnace body 2 is driven to rotate. Through this rotation, the furnace body 2 can maintain continuous rotation, ensuring that the material is heated evenly during the high-temperature activation process and avoiding uneven heating or agglomeration of the material.
[0034] During the rotation of the furnace body 2, the friction between the limiting ring 7 and the limiting wheel 8 synchronously drives the reciprocating screw 12 to rotate. Subsequently, through its cooperation with the screw sleeve 14, the reciprocating screw 12 pushes the screw sleeve 14 to slide axially, driving the piston 13 to complete the back-and-forth movement. The movement of the piston 13 drives the flow of lubricant in the drive cylinder 10, automatically delivering the lubricant from the external container to the spray plate 9 through the connecting pipe 11. The spraying system evenly sprays the lubricant onto the meshing area of the gear 5 and the annular toothed plate 4. The sprayed lubricant effectively reduces friction and wear, ensuring smooth meshing of the gear 5 and the toothed plate, reducing equipment damage and jamming caused by increased friction. At the same time, the method of removing the connecting pipe 11 from the external container avoids over-lubrication of the annular toothed plate 4.
[0035] Meanwhile, the limiting ring 7 and limiting wheel 8 can effectively ensure that the furnace body 2 will not shift or vibrate during rotation, ensuring the stable rotation of the furnace body 2 and avoiding structural damage caused by unstable rotation.
[0036] In summary, this device, through its lubrication spraying system, stable rotating structure, and effective limit design, ensures the stable operation of the activation furnace in high-temperature and high-dust environments, extends the service life of the equipment, and reduces downtime and maintenance costs caused by mechanical wear and insufficient lubrication.
[0037] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
