Description

Technical Field

[0001] This utility model relates to the technical field of rotary kiln feeding equipment, and in particular to a leak-proof carbonization and activation rotary kiln feeding inlet structure. Background Technology

[0002] Rotary kilns are key equipment for high-temperature calcination and chemical reactions of powdery and granular materials, and are widely used in material carbonization and activation processes in the chemical, metallurgical, and environmental protection fields. In these processes, the materials processed are mostly lightweight, dry powders or granules such as biomass and coal powder, whose physical properties make them highly susceptible to dust generation during conveying and feeding.

[0003] Currently, the feed inlet structure of rotary kilns is usually quite simple, often using open or semi-closed chutes or pipes to directly introduce materials into the kiln body. When the material falls from the conveying equipment to the feed inlet, due to potential energy differences and airflow disturbances, a large amount of material dust will inevitably escape outward from the gaps or openings of the feed inlet.

[0004] This dust leakage not only results in the loss of valuable raw materials, but more seriously, it directly pollutes the production workshop and even the surrounding atmosphere, posing a potential threat to the health of operators and failing to meet increasingly stringent environmental regulations. Furthermore, the open feed inlet allows outside air and impurities to easily enter the kiln, potentially interfering with the precisely controlled reaction atmosphere and affecting the quality and stability of the final product.

[0005] Therefore, how to design a feeding structure that can effectively seal the feed inlet during the feeding process and prevent dust leakage from the source has become a technical problem that urgently needs to be solved in this field.

[0006] Therefore, this utility model proposes a leak-proof carbonization activation rotary kiln feed inlet structure to address the shortcomings of the prior art. Utility Model Content

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] Example: Please refer to Figures 1 to 7 This utility model provides a leak-proof carbonization activation rotary kiln feed inlet structure, which aims to solve the technical problems of easy material blockage and easy dust leakage during feeding in the feed inlet of the rotary kiln in the prior art.

[0026] like Figure 1 , Figure 2 and Figure 6 As shown, the leak-proof carbonization activation rotary kiln feed inlet structure includes a pipe body 1, a base component 4 fixedly connected to the bottom end of the pipe body 1, a feed pipe 2 fixedly connected to the pipe body 1, and an anti-blocking mechanism 3 and a protective mechanism 5 respectively related to the feeding process. The base component 4 provides the installation and support foundation for the entire device, and includes a base plate 41, a support frame 42 fixedly connected to the base plate 41, and a fixing frame 43 fixedly connected to the top of the support frame 42. The anti-blocking mechanism 3 is used for... To prevent material from clogging when entering the feed pipe 2, it includes a feed hopper 31 fixedly connected to the top of the feed pipe 2. A support rod 32 is fixedly connected to the top of the feed hopper 31. A rotating shaft 34 passes through and is rotatably connected to the support rod 32. The rotating shaft 34 extends into the inner cavity of the feed hopper 31. Multiple stirring rods 35 are fixedly connected to the outer wall of the rotating shaft 34. A protective column 33 is fixedly connected to the top of the support rod 32. The protective column 33 provides protection at the connection between the rotating shaft 34 and the support rod 32.

[0027] To solve the above-mentioned technical problems, the core of the technical solution of this embodiment is that the leak-proof carbonization rotary kiln feed inlet structure also includes a protective mechanism 5, and the protective mechanism 5 and the aforementioned feed hopper 31 form a specific structural cooperation and connection relationship to achieve dynamic sealing during the feeding process and prevent dust leakage.

[0028] Please refer to the following carefully. Figure 1 , Figure 2 , Figure 4 and Figure 5 The core structure will be described in detail below: The protective mechanism 5 includes a feeding pipe 51, a hydraulic cylinder 52 installed outside the feeding pipe 51, a protective cover 54, a connecting ring 53, multiple moving blocks 55, multiple push rods 56, a fixed ring 57, and a moving ring 58. The feeding pipe 51 is fixedly connected to the discharge end of a transmission belt 45, which is used to transport materials in the storage bin 44 to the inlet bin 31. The connecting ring 53 is slidably sleeved on the outer wall of the feeding pipe 51 through the moving blocks 55. The protective cover 54 is fixedly connected to the bottom of the connecting ring 53. The extension and retraction end of the hydraulic cylinder 52 drives the feeding pipe 51. The moving ring 58 moves, which in turn drives the push rod 56 to move synchronously. The bottom end of the push rod 56 is fixedly connected to the fixed ring 57, and the top end of the push rod 56 drives the connecting ring 53. Under the driving action of the hydraulic cylinder 52, the connecting ring 53 drives the protective cover 54 to reciprocate along the axial direction of the feeding pipe 51. When the protective cover 54 moves down, it can cover the top opening of the feed hopper 31 to form a sealed space. This structure, which opens and closes by hydraulically driving the protective cover 54, ensures a fast and reliable seal of the feed inlet during non-feeding periods and at the moment of feeding.

[0029] Based on the above embodiments, the present invention may further include the following preferred technical solutions: In a preferred embodiment, to provide a stable and reliable driving force to the rotating shaft 34, the anti-blocking mechanism 3 also includes a power assembly 36, please refer to... Figure 2 , Figure 3 and Figure 6 The power assembly 36 includes a motor 361, a power shaft 362 whose drive end is fixedly connected to the motor 361, and a transmission gear 363 whose outer wall is fixedly connected to the power shaft 362. The motor 361 is mounted on the aforementioned fixed frame 43 and provides the original power for the operation of the entire anti-blocking mechanism 3.

[0030] As a further optimization of the transmission structure of the aforementioned power assembly 36, in order to realize the reduction and torque increase transmission from the motor 361 to the rotating shaft 34, the power assembly 36 also includes a rotatably connected connecting shaft 366, two gear disks 367 and 368 respectively fixedly connected to the two ends of the connecting shaft 366, a rotatably connected gear 301, a gear chain 302, and a gear 303 fixedly connected to the top of the rotating shaft 34. The specific transmission connection relationship is as follows: the transmission gear 363 meshes with the gear disk 367, the gear disk 368 meshes with the gear 301, and the gear 301 meshes with the gear 303 via the gear chain 302. This multi-stage gear and chain combination transmission structure can smoothly convert the high-speed rotation of the motor 361 into the low-speed, high-torque rotation of the rotating shaft 34.

[0031] As a further limitation on the installation structure of the power assembly 36, in order to protect the internal transmission parts and provide a stable installation reference, the power assembly 36 also includes a protective shell 364 fixedly connected to the outer wall of the feed hopper 31, and a plurality of fixing plates 365 installed on the inner wall of the protective shell 364. The aforementioned connecting shaft 366 is rotatably connected to the fixing plate 365. In addition, a support shaft 369 is fixedly connected to the inner wall of the top of the protective shell 364. The support shaft 369 provides rotational support for the gear 301, and the gear chain 302 slides on the inner wall of the bottom end of the support rod 32.

[0032] As a further improvement to basic component 4, please refer to Figure 1 and Figure 2 The base plate 41 in the basic component 4 is also provided with a storage bin 44 at the top. A transmission belt 45 connects the storage bin 44 and the feed bin 31 to transport materials from below to above. This structure realizes the automated continuous supply of materials.

[0033] The working principle is as follows: Before the feeding operation begins, the raw materials in the storage bin 44 are conveyed by the transmission belt 45 and prepared to enter the feed bin 31 through the feeding pipe 51. At this time, the motor 361 in the power assembly 36 starts, and its power is transmitted to the gear disk 367 through the power shaft 362 and the transmission gear 363. The rotation of the gear disk 367 drives the connecting shaft 366 and the gear disk 368 to rotate synchronously. The gear disk 368 then drives the gear 301 to rotate. Finally, the gear 301 drives the gear 303 fixed at the top of the rotating shaft 34 to rotate through the gear chain 302, thereby driving the entire rotating shaft 34 together with the stirring rod 35 on it to rotate and stir in the inner cavity of the feed bin 31. This pre-started stirring action ensures that the material can always remain in a flowing state after entering the feed bin 31, effectively avoiding blockage caused by accumulation.

[0034] At the same time as or before the material falls, the hydraulic cylinder 52 in the protective mechanism 5 starts to extend and retract. Its extension end pushes the moving ring 58 and the push rod 56 to move. The push rod 56 drives the protective cover 54 to slide down along the outer wall of the feeding pipe 51 through the connecting ring 53 until the lower edge of the protective cover 54 covers and seals the top opening of the feed hopper 31, forming a temporary sealed space. In this way, the dust generated when the material falls is completely sealed inside and cannot diffuse outward. At the same time, it also prevents the entry of external impurities. Through this synergistic effect of the protective mechanism 5 and the anti-blocking mechanism 3, this utility model solves the common problems of blockage and dust leakage at the feed inlet in the prior art, and realizes clean, efficient and continuous feeding operation.
