Description

Technical Field

[0001] This utility model relates to the field of activated carbon production technology, and more specifically, to a base lateral tilting device for a rotary kiln used for heating activated carbon. Background Technology

[0002] Activated carbon is a porous artificial carbonaceous adsorbent made from carbon-containing materials through carbonization and activation. It has a well-developed pore structure and a huge specific surface area, and can be used as an adsorbent, catalyst and catalyst carrier. The raw material is dried at a temperature of 170℃~600℃ in a rotary kiln to carbonize 80% of its organic structure.

[0003] Existing rotary kilns for activated carbon generate high temperatures at the kiln walls during heating, significantly impacting the surrounding environment and making it difficult for workers to approach. This also affects operational safety. Furthermore, when heating raw materials in a rotary kiln, it is impossible to control the amount of raw materials injected. A large quantity of raw materials can easily cause uneven heating during rotation, resulting in substandard activated carbon.

[0004] A search revealed a rotary kiln activated carbon production device disclosed in Chinese Patent No. CN222612943U. This utility model can effectively isolate heat during kiln heating, prevent heat loss, and reduce the ambient temperature. Through the coordinated use of the feeding hopper, feeding pipe, second motor, transmission rod, and auger, the amount of material fed into the kiln can be controlled during continuous feeding, preventing uneven heating caused by excessive material addition.

[0005] However, in actual use, the rotary kiln activated carbon production device has a problem: because the main body of the rotary kiln is fixed to the base, the space between the bottom and the downward-facing mechanical parts of the rotary kiln is small, making it inconvenient for staff to maintain them and affecting the maintenance efficiency of the rotary kiln. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a base lateral tilting device for a rotary kiln for heating activated carbon, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A base-side tilting device for a rotary kiln used for heating activated carbon includes a base frame. A positioning frame one is fixedly connected to the top of the base frame, and a positioning frame two is fixedly connected to the upper surface of the base frame. A servo motor is fixedly connected to the top of the positioning frame one, and a reducer is fixedly connected to the output end of the servo motor. A gear one is fixedly connected to the output end of the reducer. The outer side of the gear one is rotatably connected to the inner side of the positioning frame two. A rotary kiln body is arranged above the base frame. Multiple supports are fixedly connected to the inner side of the rotary kiln body. A tilting mechanism is arranged on the outer side of the rotary kiln body, and a support mechanism is arranged on the top of the base frame.

[0009] By adopting the above technical solution, the activated carbon is stirred, dispersed and conveyed by multiple supports, and a stable driving force is provided to the rotary kiln body by a servo motor and a reducer.

[0010] As a further description of the above technical solution: the tilting mechanism includes two load-bearing frames. The bottom of the load-bearing frame is fixedly connected to the upper surface of the base frame. A limiting ring is hinged to the top of the load-bearing frame. A pad is fixedly connected to one side of the limiting ring. Multiple rollers are rotatably connected to the inner side of the limiting ring. The outer side of the rollers is rotatably connected to the inner side of the rotary kiln body. Three fixing rings are fixedly connected to the outer side of the rotary kiln body. A rotating ring is rotatably connected to the inner side of the fixing ring. A support is fixedly connected to one side of the rotating ring. A cylinder is rotatably connected to the outer side of the support. A pad is hinged to the bottom of the cylinder. The bottom of the pad is fixedly connected to the top of the base frame.

[0011] By adopting the above technical solution, the rotary kiln body is rotated by the support of multiple rollers and limiting rings through the load-bearing frame, using three cylinders to push the rotating ring and the fixed ring. This causes the bottom of the rotary kiln body to face one side, making it easier for workers to inspect and replace the bottom and inner parts of the rotary kiln body.

[0012] As a further description of the above technical solution: the support mechanism includes two hydraulic cylinders, an arc-shaped base is fixedly connected to the top of the hydraulic cylinders, three rollers are rotatably connected to the inner side of the arc-shaped base, and a gear is fixedly connected to the outer side of the rotary kiln body, with the outer side of the gear meshing with one side of the gear.

[0013] By adopting the above technical solution, two hydraulic cylinders are used to push the bottom of the arc-shaped base and three rollers to provide arc-shaped support, so that the rotary kiln body can maintain stable operation after repeated turning and maintenance.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] 1. By setting up a side-tilting mechanism, compared with the existing technology, the rotary kiln body can be tilted to one side during maintenance by utilizing the deflection of the load-bearing frame and the limiting ring. This completely exposes the key components of the rotary kiln body that were originally facing down or inward, making them an easily accessible vertical working surface. This facilitates the maintenance and operation space for staff, simplifies the maintenance and replacement process, and improves the maintenance efficiency of the rotary kiln body.

[0016] 2. By setting up a support mechanism, compared with the existing technology, multiple rollers with lifting and arc-shaped settings are used to provide close rolling support for the rotary kiln body after deflection. This allows the rotary kiln body to receive timely support after maintenance, and ensures the stability of the rotary kiln body after repeated inspections and maintenance.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] The embodiments disclosed in this application are as follows: Figure 1-6 The shown base-side tilting device for a rotary kiln used for activated carbon heating includes a base frame 1. A positioning frame 2 is fixedly connected to the top of the base frame 1, and a positioning frame 3 is fixedly connected to the upper surface of the base frame 1. A servo motor 4 is fixedly connected to the top of the positioning frame 2. A reducer 5 is fixedly connected to the output end of the servo motor 4. A gear 6 is fixedly connected to the output end of the reducer 5. The outer side of the gear 6 is rotatably connected to the inner side of the positioning frame 3. A rotary kiln body 7 is set above the base frame 1. Multiple supports 8 are fixedly connected to the inner side of the rotary kiln body 7. A tilting mechanism is set on the outer side of the rotary kiln body 7. A support mechanism is set on the top of the base frame 1. The servo motor 4, reducer 5, and gear 6 provide stable drive for the rotary kiln body 7 and gear 21.

[0026] Reference Figure 1 , Figure 4 and Figure 5 As shown, the tilting mechanism includes two load-bearing frames 9. The bottom of the load-bearing frame 9 is fixedly connected to the upper surface of the base frame 1. A limit ring 10 is hinged to the top of the load-bearing frame 9. A pad 12 is fixedly connected to one side of the limit ring 10. Multiple rollers 11 are rotatably connected to the inner side of the limit ring 10. The outer side of the rollers 11 is rotatably connected to the inner side of the rotary kiln body 7. Three fixing rings 13 are fixedly connected to the outer side of the rotary kiln body 7. A rotating ring 14 is rotatably connected to the inner side of the fixing rings 13. A support is fixedly connected to one side of the rotating ring 14. A cylinder 16 is rotatably connected to the outer side of the support 15. A pad 17 is hinged to the bottom of the cylinder 16. The bottom of the pad 17 is fixedly connected to the top of the base frame 1. The two cylinders 16 push the rotary kiln body 7 by rotating the ring 14 and fixing the ring 13. The load-bearing frame 9 is used to hinge the limiting ring 10 and the roller 11, so that the rotary kiln body 7 can be flipped over above the load-bearing frame 9. The top of the rotary kiln body 7 can be flipped to one side, which is convenient for the staff to inspect and replace it.

[0027] Reference Figure 2 and Figure 6 As shown, the support mechanism includes two hydraulic cylinders 18. An arc-shaped base 19 is fixedly connected to the top of the hydraulic cylinders 18. Three rollers 20 are rotatably connected to the inner side of the arc-shaped base 19. A gear 21 is fixedly connected to the outer side of the rotary kiln body 7. The outer side of the gear 21 meshes with one side of the gear 6. The arc-shaped base 19 and the three rollers 20 are used to fit against the surface of the rotary kiln body 7 and provide rolling support.

[0028] The working principle of this utility model is as follows: When the rotary kiln body 7 heats the activated carbon, the servo motor 4 and the reducer 5 drive gear 6 to mesh with gear 21, which in turn drives the rotary kiln body 7 and multiple supports 8 to stir and transport the activated carbon inside the rotary kiln body 7. Then, an external heating mechanism heats the activated carbon inside the rotary kiln body 7. After the rotary kiln body 7 is finished and needs maintenance, the two hydraulic cylinders 18 are retracted, causing them to move the arc-shaped base 19 and three rollers 20 to release the rolling support at the bottom of the rotary kiln body 7. This allows the weight of the rotary kiln body 7 to be distributed to the bottom support frame 9 via multiple rollers 11 and two limit rings 10. Then, the three cylinders 16 are activated to push the support 15 and the rotating ring 14, thereby applying a force that tilts the rotary kiln body 7 to one side. Then, the three cylinders 16 are activated to apply pressure to the tilted rotary kiln body 7, allowing the rotary kiln body 7 to slowly flip to one side of the base frame 1, so that one side of the rotary kiln body 7 contacts the surface of the base frame 1. After the rotary kiln body 7 is flipped and placed still, it is convenient for the staff to inspect and maintain the bottom of the rotary kiln body 7. Finally, the three cylinders 16 are activated again to pull the rotating ring 14 and the fixing ring 13 to pull the rotary kiln body 7 to one side again, so that the rotary kiln body 7 is back to be upright above the base frame 1 under the hinged support of the two limit rings 10, the rollers 11 and the load-bearing frame 9. Then, the two hydraulic cylinders 18 are restarted to drive the arc-shaped base 19 and the three rollers 20 to roll and support the bottom of the rotary kiln body 7, and the gear 21 re-engages with one side of the gear 6. Finally, the rotary kiln body 7 is put back into the work of heating activated carbon.
