Description

Technical Field

[0001] The utility model relates to the technical field of steel rolling technology, and particularly relates to a detachable pipeline device. Background Technique

[0002] In the field of large-scale industrial manufacturing, especially in the general factory of the seamless steel pipe processing industry, the tempering heat treatment furnace is one of the indispensable key equipment, which is directly related to the quality and production efficiency of steel products. Such heat treatment furnaces usually rely on a complex and precise gas supply system to provide a stable and controllable heat source to meet the strict temperature requirements in different process stages;

[0003] However, in the actual operation process, due to the complexity of the gas pipeline system design and the characteristics of the gas itself, especially in the branch sections and bends with a small pipeline diameter, these impurities are easy to deposit and gradually accumulate to form dirt. This accumulation of dirt will not only gradually reduce the effective flow area of the pipeline, resulting in a significant decrease in the gas throughput, thereby affecting the temperature uniformity and stability in the heat treatment furnace. More seriously, with the continuous accumulation of dirt, some pipelines may be severely blocked, completely blocking the gas flow, forcing the production to be interrupted, and having a serious impact on the production plan and progress. In the past, measures were taken to replace the entire pipeline, resulting in losses and wasted time. Therefore, we propose a detachable pipeline device to solve the above problems.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model. Embodiment

[0024] As Figures 1-5As shown in the figure, a detachable pipeline device proposed in an embodiment of the present utility model includes a main pipeline 1. Two connecting pipes 2 are connected and fixed to the right side of the main pipeline 1. A sealing sleeve 3 is fixedly connected to the connecting pipe 2. The same sub-pipeline 4 is in movable contact with the two sealing sleeves 3. Two cavities 5 are opened in the sealing sleeve 3. A sliding ring 6 is slidably connected to the connecting pipe 2. The same connecting plate 7 is welded between the two sliding rings 6. Two moving rods 8 are fixedly connected to one side of the sliding ring 6. The end of the moving rod 8 extends into the corresponding cavity 5 and is rotatably connected to an inclined hinge rod 9. A fixed rod 10 is welded to one side inner wall of the cavity 5. A latch 11 is slidably connected to the fixed rod 10. A first spring 12 is welded between the end of the latch 11 and one side inner wall of the corresponding cavity 5. The first spring 12 is movably sleeved on the corresponding fixed rod 10. Two sealing rings 13 are fixedly connected to the sub-pipeline 4. Two mounting blocks 14 are fixedly connected to one side of the sealing ring 13. A clamping groove 15 is opened on one side of the mounting block 14. The clamping groove 15 is clamped with the corresponding latch 11. The end of the hinge rod 9 is hinged to one side of the corresponding latch 11. Move the connecting plate 7. The connecting plate 7 drives the sliding ring 6 to slide on the corresponding connecting pipe 2 and stretches the second spring 17. The sliding ring 6 drives the corresponding hinge rod 9 to move and rotate through the moving rod 8. The hinge rod 9 drives the corresponding latch 11 to slide on the fixed rod 10 and compresses the first spring 12, so that the latch 11 is separated from the corresponding clamping groove 15. Then move the sub-pipeline 4. The sub-pipeline 4 drives the mounting block 14 to be separated from the sealing sleeve 3 through the sealing ring 13. After removal, let the external iron wire penetrate through the elbow repeatedly until the dirt is removed, and then install the sub-pipeline 4. By designing it into a split and detachable pipeline, the operation is simple, easy to penetrate and reinstall, reducing the insufficient gas flow caused by pipeline blockage, and thus solving the problem of uneven heating temperature of the steel during heating. Uneven heating temperature of the steel will cause uneven performance and there are potential quality and safety hazards.

[0025] In some embodiments, a second spring 17 is welded between the other side of the sliding ring 6 and the right side of the main pipeline 1. The second spring 17 is movably sleeved on the corresponding connecting pipe 2. The setting of the second spring 17 plays a role in resetting.

[0026] In some embodiments, a rectangular hole 16 is opened on the other side inner wall of the cavity 5. The inner wall of the rectangular hole 16 is in movable contact with the outer side of the corresponding mounting block 14. The setting of the mounting block 14 plays a role in connection.

[0027] In some embodiments, a guiding hole is opened on the left side inner wall of the cavity 5. The guiding hole is slidably connected to the corresponding moving rod 8. The setting of the moving rod 8 plays a role in connection.

[0028] In some embodiments, a limiting groove is formed on the clamping pin 11. The clamping pin 11 is slidably connected to the corresponding fixed rod 10 through the limiting groove. The setting of the fixed rod 10 plays a role in limiting.

[0029] In some embodiments, one side of the sealing ring 13 is in movable contact with one side of the corresponding sealing sleeve 3. The setting of the sealing ring 13 plays a role in connection.

[0030] Working principle or structural principle: During use, move the connecting plate 7. The connecting plate 7 drives the sliding ring 6 to slide on the corresponding connecting pipe 2 and stretch the second spring 17. The sliding ring 6 drives the corresponding hinge rod 9 to move and rotate through the moving rod 8. The hinge rod 9 drives the corresponding clamping pin 11 to slide on the fixed rod 10 and compress the first spring 12, so that the clamping pin 11 is separated from the corresponding clamping groove 15. Immediately afterwards, move the sub-pipeline 4. The sub-pipeline 4 drives the mounting block 14 to be separated from the sealing sleeve 3 through the sealing ring 13. After removal, repeatedly pass the external iron wire through the elbow until the dirt is removed, and then install the sub-pipeline 4. During installation, move the connecting plate 7. The connecting plate 7 drives the sliding ring 6 to slide on the corresponding connecting pipe 2 and stretch the second spring 17. The sliding ring 6 drives the corresponding hinge rod 9 to move and rotate through the moving rod 8. The hinge rod 9 drives the corresponding clamping pin 11 to slide on the fixed rod 10 and compress the first spring 12. Immediately afterwards, insert the sub-pipeline 4 onto the sealing sleeve 3. The sub-pipeline 4 drives the corresponding mounting block 14 to move through the sealing ring 13, so that the mounting block 14 is inserted into the corresponding cavity 5. When one side of the sealing ring 13 contacts one side of the sealing sleeve 3, release the force on the connecting plate 7. The first spring 12 in the compressed state resets. Under the action of its own elastic force, the first spring 12 drives the corresponding clamping pin 11 to be clamped with the clamping groove 15, thereby connecting the sub-pipeline 4 to the main pipeline 1.
