Description

Technical Field

[0001] This utility model relates to the field of rotary kiln head sealing technology, specifically a novel rotary kiln head sealing device. Background Technology

[0002] Rotary kilns are used in the metallurgical industry for the magnetization roasting of lean iron ore in steel plants. As the "heart" of cement enterprises, cement rotary kilns currently operate under negative pressure. If there is excessive air leakage at the kiln head or tail, it will reduce the amount of secondary air. Cold air leaking into the kiln from the kiln head or tail will lower the temperature at the kiln head or tail. Consequently, in order to ensure temperature stability, fuel consumption needs to be increased, and normal ventilation inside the kiln will also be affected, resulting in a reduction in product quality.

[0003] For example, patent document CN 211739840 U discloses a novel rotary kiln head sealing device, including a kiln head, a connector on one side of the kiln head, a first sealing block mounted on the surface of the kiln head, a second sealing block mounted on the surface of the connector, a fixing locking block fixedly connected to the surfaces of the first and second sealing blocks, a sealing soft block fixedly connected to one side of the fixing locking block, a through hole on the surface of the fixing locking block, a fixing screw installed in the through hole of the fixing locking block, a nut at one end of the fixing screw, and a leak-proof bag fixedly connected to one side of the first and second sealing blocks. This utility model, by setting up a first and second sealing block, and by inserting the fixing screw into the through hole of the fixing locking block and tightening the nut, achieves a highly efficient sealing effect through the mutual compression of the sealing soft blocks, resulting in a complete seal between the first and second sealing blocks.

[0004] However, in actual use, this structure can only be used for simple docking and fixing. The docking point cannot be tightly interlocked and tightened. When there is excessive atmospheric pressure inside the pipeline, deformation is very likely to occur. At the same time, the equipment cannot perform a more comprehensive cover protection operation for the entire connection, which cannot meet the daily use needs. Therefore, it is urgent to design a new type of rotary kiln head sealing device to solve the above problems. Summary of the Invention

[0005] The purpose of this utility model is to provide a novel rotary kiln head sealing device to solve the problems mentioned in the background art. In actual use, the existing structure can only perform simple docking and fixing, and the docking point cannot be tightly locked. Subsequently, when there is excessive atmospheric pressure inside the pipeline, deformation is very likely to occur. At the same time, the device cannot perform more comprehensive cover protection of the entire connection point, which cannot meet the needs of daily use.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a novel rotary kiln head sealing device, comprising a first connecting seat, a first connecting pipe disposed inside the first connecting seat, a second connecting seat disposed at one end of the first connecting pipe, and a second connecting pipe sleeved on the outer surface of the second connecting seat;

[0007] A first snap-fit ​​ring seat and a second snap-fit ​​ring seat are provided. The outer surface of the first connecting seat is fitted with a first snap-fit ​​ring seat, and the outer surface of the second connecting tube is fitted with a second snap-fit ​​ring seat.

[0008] Preferably, a conical protective cover is provided at one end of the first snap ring seat and the second snap ring seat that are far apart from each other, and a sealing plug seat is movably connected to one end of the first snap ring seat through the conical protective cover.

[0009] Preferably, a protective cover is provided at one end of the first snap ring seat and the second snap ring seat that are close to each other, and a protective ring seat is provided at one end of the protective cover.

[0010] Preferably, the inner walls of the first and second snap-fit ​​ring seats are provided with a first sealing gasket, and the sides of the first connecting seat and the second connecting tube are provided with a second sealing gasket.

[0011] Preferably, the bottom of the first connecting seat and the second connecting pipe is provided with an air control pipe.

[0012] Preferably, a reinforcing ring seat is provided inside the space between the first connecting seat and the second connecting pipe, and a reinforcing airbag is provided on the back of the reinforcing ring seat.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This novel rotary kiln head sealing device, through its first connecting seat, first connecting pipe, second connecting seat, second connecting pipe, conical cover, sealing plug, air control pipe, reinforcing ring seat, and reinforcing airbag, enables a more robust sealing connection of the rotary kiln head. In actual use, the operator first connects the first connecting seat and the second connecting pipe. Then, one end of the first connecting seat is sealed to the rotary kiln head via the conical cover and sealing plug. Simultaneous air inflation is then performed through the air control pipe, causing the reinforcing airbags at the inner edges of the first and second connecting pipes to extend and retract, fitting the two sets of reinforcing ring seats into the connection between the first and second connecting pipes. This reinforces the vulnerable first and second connecting pipes, preventing deformation due to excessive internal air pressure and ensuring a tight seal, demonstrating the practicality of the device design.

[0015] This novel rotary kiln head sealing device, through the arrangement of a first connecting seat, a second connecting pipe, a first snap-fit ​​ring seat, a second snap-fit ​​ring seat, a protective cover, a protective ring seat, a first sealing gasket, and a second sealing gasket, further improves the overall performance of the equipment. During daily use, operators place the second snap-fit ​​ring seat and the conical cover onto the first connecting seat and the second connecting pipe, respectively. At this time, the second sealing gaskets on the sides of the first connecting seat and the second connecting pipe can seal against the first sealing gaskets on the inner walls of the first and second snap-fit ​​ring seats. Simultaneously, the protective ring seat between the second snap-fit ​​ring seat and the conical cover can be stretched and connected using the protective cover, thus achieving overall protection between the first connecting seat and the second connecting pipe. The conical cover at one end of the first and second snap-fit ​​ring seats can also be used for protection of the rotary kiln head discharge pipe, demonstrating the comprehensiveness of the equipment design.

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.

[0022] Please see Figure 1-4 One embodiment provided by this utility model:

[0023] A novel rotary kiln head sealing device includes a first connecting seat 1, a first connecting pipe 2 inside the first connecting seat 1, a second connecting seat 3 at one end of the first connecting pipe 2, a second connecting pipe 4 sleeved on the outer surface of the second connecting seat 3, an air control pipe 13 at the bottom of the first connecting seat 1 and the second connecting pipe 4, a reinforcing ring seat 14 inside between the first connecting seat 1 and the second connecting pipe 4, and a reinforcing airbag 15 on the back of the reinforcing ring seat 14. One end of the first connecting seat 1 is sealed at the rotary kiln head through a conical cover 7 and a sealing plug seat 8. By using the air control pipe 13, air can be synchronously injected into the interior of the first connecting seat 1 and the second connecting pipe 4, causing the reinforcing airbag 15 at the inner edge of the first connecting seat 1 and the second connecting pipe 4 to extend and retract, thus fitting the two sets of reinforcing ring seats 14 into the connection between the first connecting pipe 2 and the second connecting seat 3.

[0024] A first snap-fit ​​ring seat 5 and a second snap-fit ​​ring seat 6 are provided. The outer surface of the first connecting seat 1 is fitted with the first snap-fit ​​ring seat 5, and the outer surface of the second connecting pipe 4 is fitted with the second snap-fit ​​ring seat 6. A conical protective cover 7 is provided at the ends of the first snap-fit ​​ring seat 5 and the second snap-fit ​​ring seat 6 that are far apart from each other. A sealing plug seat 8 is movably connected to one end of the first snap-fit ​​ring seat 5 through the conical protective cover 7. A protective rubber cover 9 is provided at the ends of the first snap-fit ​​ring seat 5 and the second snap-fit ​​ring seat 6 that are close to each other. A protective ring seat 10 is provided at one end of the protective rubber cover 9. A first sealing gasket 11 is provided on the inner wall of the first snap-fit ​​ring seat 5 and the second snap-fit ​​ring seat 6. A second sealing gasket 12 is provided on the side of the first connecting seat 1 and the second connecting pipe 4. The second snap-fit ​​ring seat 6 and the conical protective cover 7 are respectively fitted onto the first connecting seat 1 and the second connecting pipe 4. At this time, the second sealing gasket 12 on the side of the first connecting seat 1 and the second connecting pipe 4 can be sealed and connected with the first sealing gasket 11 on the inner wall of the first snap-fit ​​ring seat 5 and the second snap-fit ​​ring seat 6.

[0025] Working Principle: During use, the operator first connects the first connecting pipe 2 and the second connecting pipe 3 between the first connecting seat 1 and the second connecting pipe 4. Then, one end of the first connecting seat 1 is sealed to the rotary kiln head via the conical shield 7 and the sealing plug seat 8. Simultaneous air inflation is then performed through the air control pipe 13, causing the reinforcing airbags 15 at the inner edges of the first connecting seat 1 and the second connecting pipe 4 to extend and retract, thus fitting the two sets of reinforcing ring seats 14 to the connection point of the first connecting pipe 2 and the second connecting seat 3. This reinforces the vulnerable first connecting pipe 2 and the second connecting seat 3, preventing deformation due to excessive internal air pressure, which could affect the connection. Regarding the interface sealing issue, during daily use, the operator places the second snap-fit ​​ring seat 6 and the conical protective cover 7 onto the first connecting seat 1 and the second connecting pipe 4, respectively. At this time, the second sealing gasket 12 on the side of the first connecting seat 1 and the second connecting pipe 4 can be sealed and connected with the first sealing gasket 11 on the inner wall of the first snap-fit ​​ring seat 5 and the second snap-fit ​​ring seat 6. At the same time, the protective ring seat 10 between the second snap-fit ​​ring seat 6 and the conical protective cover 7 can be stretched and connected through the protective rubber cover 9, thereby achieving the overall cover-and-protection operation between the first connecting seat 1 and the second connecting pipe 4. The conical protective cover 7 at one end of the first snap-fit ​​ring seat 5 and the second snap-fit ​​ring seat 6 can also be used for the cover-and-protection operation of the rotary kiln head discharge pipe. The above is the complete working principle of this utility model.
