Description

Technical Field

[0001] The utility model relates to the technical field of tobacco processing equipment, in particular to a flexible connection of a hot air flow pipeline. Background Art

[0002] In a tobacco leaf primary processing production workshop, many large-scale devices are used, such as a tobacco leaf conditioner, a tobacco dryer, etc., which require hot air to heat materials. For these devices operating in high-temperature and high-pressure environments, the joints of the hot air flow pipelines inevitably face severe challenges of thermal expansion and contraction. Coupled with the shaking generated during mechanical operation, over time, it is extremely easy to cause stress concentration in the pipelines, which in turn leads to loose fitting at the joints, and even potential problems such as rupture and leakage. Content of the Utility Model

[0003] In order to overcome at least one of the above-mentioned defects of the prior art, the utility model provides a flexible connection of a hot air flow pipeline to solve the problems that large stresses are generated at the joints of the hot air flow pipelines, resulting in loose fitting at the joints, and even rupture and leakage.

[0004] The technical solution adopted by the utility model to solve its problems is as follows:

[0005] A flexible connection of a hot air flow pipeline includes: a flared connector, there are two flared connectors, one end of one flared connector is connected to one end of the other flared connector; a pipeline, and the pipeline is connected end to end with the flared connector at the connection part.

[0006] Through the above solution, one end of the flared connector is wider and the other end is narrower. Such a design helps to provide a larger surface area at the joint, thereby dispersing stress and reducing the local pressure caused by thermal expansion and contraction. This shape also helps the gas flow more smoothly, reducing the pressure loss when the gas passes through the connection part. When the pipeline system expands or contracts due to temperature changes, the relative displacement between the double flared connectors can absorb these changes and protect the pipeline from damage.

[0007] Further, one end of the flared connector is provided with a pipe connection splicing ring, and the other end is provided with a flexible connection splicing ring. The flexible connection splicing ring on one flared connector is connected to the flexible connection splicing ring on the other flared connector.

[0008] Through the above further solution, the pipe connection splicing ring can enhance the connection strength between the pipeline and the flared connector, ensure the tight fit between the two, and avoid leakage caused by loose connection. The flexible connection splicing ring enables flexible connection between the two flared connectors, allows the pipeline system to have a certain expansion and contraction space during thermal expansion and contraction or mechanical vibration, and reduces the direct stress transmission between the pipelines.

[0009] Furthermore, a flange is provided at the end of the pipe, and the flange is connected to the pipe connection splicing ring.

[0010] With the above further solution, flange connection allows each part in the pipeline system to be easily disassembled and reinstalled, which is very useful for regular inspection, cleaning, maintenance or replacement of components.

[0011] Furthermore, it also includes a soft connection sealing strip ring. There are two soft connection sealing strip rings, and the two soft connection sealing strip rings are attached to the opposite sides of the connected sides of the two soft connection splicing rings.

[0012] With the above further solution, the soft connection sealing strip ring can press the two soft connection splicing rings tightly to ensure that there is no leakage at the connection between the two bell-shaped connectors.

[0013] Furthermore, it also includes a pipe connection sealing strip ring. There are two pipe connection sealing strip rings, and the pipe connection sealing strip rings are attached to the opposite sides of the connected sides of the pipe connection splicing ring and the flange.

[0014] With the above further solution, the pipe connection sealing strip ring presses the pipe connection splicing ring tightly on the flange to ensure a tighter connection between the flange and the pipe connection splicing ring and reduce the possibility of leakage.

[0015] Furthermore, the bell-shaped connector is made of high-temperature resistant flexible material.

[0016] With the above further solution, using high-temperature resistant material can ensure that the connector still maintains its performance in high-temperature environment, and the flexible material can absorb the stress generated by the thermal expansion and contraction of the pipe, reducing the potential damage risk brought by the rigid connection of the pipeline system.

[0017] Furthermore, a number of uniformly arranged through holes are provided on the pipe connection splicing ring, soft connection splicing ring, flange, soft connection sealing strip ring and pipe connection sealing strip ring.

[0018] Furthermore, it also includes a screw and a nut. The screw sequentially passes through the through holes on a soft connection sealing strip ring, a soft connection splicing ring, another soft connection splicing ring and another soft connection sealing strip ring and is threadedly connected to the nut. The screw sequentially passes through the through holes on the flange, pipe connection splicing ring and pipe connection sealing strip ring and is threadedly connected to the nut.

[0019] Through the above further solution, by tightening the screw and nut, the tight combination between each connecting component can be ensured, the connection strength can be improved, and loosening or separation caused by external forces can be prevented. The screw passes through the soft connection sealing strip ring or the pipe connection sealing strip ring and is tightened, which can ensure that the soft connection sealing strip ring or the pipe connection sealing strip ring presses the soft connection splicing ring or the pipe connection splicing ring, thereby improving the sealing performance and reducing the risk of leakage.

[0020] In summary, a flexible connection for a hot air flow pipeline provided by the present utility model has the following technical effects:

[0021] 1. The flared connector helps to provide a larger surface area at the connection, thereby dispersing stress, reducing local pressure caused by thermal expansion and contraction, and also helps the gas flow more smoothly, reducing the pressure loss when the gas passes through the connection part. When the pipeline system expands or contracts due to temperature changes, the relative displacement between the double flared connectors can absorb these changes and protect the pipeline from damage.

[0022] 2. The flared connector uses high-temperature resistant flexible materials, which can absorb the stress generated by the thermal expansion and contraction of the pipeline, reducing fatigue and damage at the connection part.

[0023] 3. The design of the soft connection sealing strip ring and the pipe connection sealing strip ring can improve the sealing performance and ensure the sealing of the connection. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Embodiment 1:

[0035] Refer to Figures 1 - 5 As shown, a flexible connection of a hot air flow pipeline includes: a trumpet-shaped connector 1 and a pipeline 2. There are two trumpet-shaped connectors 1. One end of the trumpet-shaped connector 1 is provided with a pipe connection splicing ring 11, and the other end is provided with a flexible connection splicing ring 12. The flexible connection splicing ring 12 on one trumpet-shaped connector 1 is connected to the flexible connection splicing ring 12 on the other trumpet-shaped connector 1. The pipe connection splicing ring 11 can enhance the connection strength between the pipeline 2 and the trumpet-shaped connector 1, ensure the tight fit between the two, and avoid leakage caused by loose connection. The flexible connection splicing ring 12 enables flexible connection between the two trumpet-shaped connectors 1, allows the pipeline 2 system to have a certain expansion and contraction space during thermal expansion and contraction or mechanical vibration, and reduces the direct stress transmission between the pipelines 2.

[0036] Among them, soft connection sealing bead rings 3 are provided on the opposite sides of the connected sides of the two soft connection splicing rings 12. The soft connection sealing bead rings 3 can press the two soft connection splicing rings 12 tightly to ensure that there is no leakage at the connection between the two horn-shaped connectors 1.

[0037] Among them, one end of the horn-shaped connector 1 is wider and the other end is narrower. Such a design helps to provide a larger surface area at the connection, thereby dispersing stress and reducing local pressure caused by thermal expansion and contraction. This shape also helps the gas flow more smoothly, reducing the pressure loss when the gas passes through the connection part. When the pipeline 2 system expands or contracts due to temperature changes, the relative displacement between the double horn-shaped connectors 1 can absorb these changes and protect the pipeline 2 from damage.

[0038] It should be noted that the horn-shaped connector 1 is made of high-temperature resistant flexible material. Using high-temperature resistant material can ensure that the connector still maintains its performance in a high-temperature environment. The flexible material can absorb the stress generated by the thermal expansion and contraction of the pipeline 2, reducing the potential damage risk brought by the rigid connection of the pipeline 2 system.

[0039] A flange 21 is provided at the end of the pipeline 2. The flange 21 is connected to the pipe connection splicing ring 11. The flange 21 connection allows each part in the pipeline 2 system to be easily disassembled and reinstalled, which is very useful for regular inspection, cleaning, maintenance or replacement of components.

[0040] Among them, pipe connection sealing bead rings 4 are provided on the opposite sides of the connected sides of the pipe connection splicing ring 11 and the flange 21. The pipe connection sealing bead rings 4 press the pipe connection splicing ring 11 tightly on the flange 21 to ensure a tighter connection between the flange 21 and the pipe connection splicing ring 11 and reduce the possibility of leakage.

[0041] A number of uniformly arranged through holes 5 are provided on the pipe connection splicing ring 11, the soft connection splicing ring 12, the flange 21, the soft connection sealing bead ring 3 and the pipe connection sealing bead ring 4. It is threadedly connected with a nut 7 by passing through the through holes 5 on a soft connection sealing bead ring 3, a soft connection splicing ring 12, another soft connection splicing ring 12 and another soft connection sealing bead ring 3 in sequence. The screw rod 6 passes through the through holes 5 on the flange 21, the pipe connection splicing ring 11 and the pipe connection sealing bead ring 4 in sequence and is threadedly connected with the nut 7. Through the fastening of the screw rod 6 and the nut 7, the tight combination between each connecting component can be ensured, the connection strength can be improved, and loosening or separation caused by external force can be prevented. When the screw rod 6 passes through the soft connection sealing bead ring 3 or the pipe connection sealing bead ring 4 and is fastened, it can ensure that the soft connection sealing bead ring 3 or the pipe connection sealing bead ring 4 presses the soft connection splicing ring 12 or the pipe connection splicing ring 11 tightly, thereby improving the sealing performance and reducing the risk of leakage.

[0042] For further expansion of this embodiment, by installing this device at the connection points between each hot air duct 2, the stress generated due to thermal expansion and contraction and mechanical vibration can be effectively eliminated. This device has a simple structure, low usage cost, and is convenient for disassembly and assembly.

[0043] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
