Description
Technical Field
[0001] This utility model relates to the field of chute steam pipeline technology, and in particular to an improved chute steam pipeline cutting structure. Background Technology
[0002] Sluices are widely used as efficient material conveying equipment; they can be used to convey various powdery, granular, or slurry materials. At the same time, in order to meet specific production process requirements, such as preventing material adhesion, improving material flowability, and assisting material handling, steam pipelines are often used in conjunction with sluices. Steam is introduced into the sluice through the steam pipeline, and the heat of the steam can be used to regulate the temperature of the material in the sluice, thereby achieving control over the material state.
[0003] In existing technologies, some steam pipelines are often used in conjunction with chutes. However, during actual use, they cannot effectively cut off and regulate the steam inside the chutes, which can lead to steam leakage. This leakage may pose a threat to the safety of surrounding equipment and operators. Moreover, when the production process requires frequent start-up and shutdown of steam supply, the traditional cutting-off structure has a slow response speed and cannot meet the requirements of process changes in a timely manner. Therefore, in order to address the above problems, an improved chute steam pipeline cutting-off structure is proposed. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an improved steam pipeline cutting structure for chutes, which aims to improve the problem that existing technologies cannot quickly cut off steam pipelines inside chutes.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an improved chute steam pipeline cutting structure, comprising a chute pipe, a feed pipe fixedly connected to the top of the chute pipe, a limiting block fixedly connected inside the feed pipe, a connecting cylinder one fixedly connected inside the limiting block, a sealing assembly for engaging inside the connecting cylinder one, a connecting cylinder two slidably connected outside the sealing assembly, a connecting ring fixedly connected to the outside of both the connecting cylinder one and the connecting cylinder two, a sealing groove formed on the outside of the connecting ring, a fastening assembly for limiting the position installed outside the sealing assembly, a steam generator fixedly connected inside the connecting cylinder two, two arc-shaped mounting blocks fixedly connected inside the connecting cylinder two, a rotating pipe rotatably connected to the adjacent side of the two arc-shaped mounting blocks, a conveying pipe fixedly connected inside the rotating pipe, a connecting column fixedly connected outside the conveying pipe, and a driving power assembly fixedly connected outside the connecting cylinder two.
[0006] As a further description of the above technical solution:

[0008] As a further description of the above technical solution:
[0009] The fastening assembly includes a retaining ring 1, which is rotatably connected to the outside of the sealing assembly. A rotating block is rotatably connected to the outside of the retaining ring 1, and a retaining ring 2 is rotatably connected to the inside of the rotating block. Both retaining ring 1 and retaining ring 2 are fixedly connected to the outside of a connecting block, and a bolt is threaded into the inside of the connecting block.
[0010] As a further description of the above technical solution:
[0011] The power assembly includes a cylinder, which is fixedly connected to the outside of the connecting cylinder 2. A push rod is fixedly connected to the drive end of the cylinder, and a rack plate is fixedly connected to the outside of the push rod. The connecting column is located outside the cylinder.
[0012] As a further description of the above technical solution:
[0013] The outside of the rotating tube is rotatably connected to the inside of the connecting cylinder two, and the outside of the conveying tube is rotatably connected to the inside of the connecting cylinder two.
[0014] As a further description of the above technical solution:

[0019] The outer side of the rack plate is meshed with the outer side of the gear, and the outer side of the gear is fixedly connected to the outer side of the limiting plate.
[0020] This utility model has the following beneficial effects:
[0021] 1. In this utility model, through the linkage mechanism of cylinder, push rod, rack and pinion, and gear, when the cylinder is activated, it can accurately drive the rotating tube to rotate, thus de-connecting the internal channel of the connecting cylinder two with the channel of the conveying pipe, achieving the cutoff of steam. Furthermore, the arc-shaped mounting block can contact the rotating tube when it reaches the predetermined cutoff position, restricting its continued rotation and ensuring the accuracy and stability of steam cutoff. This effectively avoids energy waste or other safety problems caused by inaccurate steam cutoff, ensuring the safety and reliability of the related equipment operation.
[0022] 2. In this utility model, multiple sealing measures are adopted during the installation and connection of connecting cylinder one and connecting cylinder two. First, the sealing cylinder slides inside the two connecting cylinders, causing the connecting ring to contact the limiting ring, and the sealing ring is engaged in the sealing groove to achieve an initial seal. Then, retaining ring one and retaining ring two rotate outside the limiting ring and connecting ring, and are tightened by connecting blocks and bolts to achieve a secondary seal. This double sealing design effectively prevents steam leakage from the connection point, reduces steam loss, improves energy utilization efficiency, and also avoids the safety hazards and environmental impacts that steam leakage may cause.

[0030] 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.
[0031] Reference Figures 1 to 3 As shown, this utility model provides an embodiment of an improved chute steam pipeline cutting structure, including a chute pipe 1, which serves as the main channel for material conveying. A discharge pipe 2 is fixedly connected to the top of the chute pipe 1. The discharge pipe 2 is inclined and tightly connected to the chute pipe 1, accurately guiding materials to fall into the chute pipe 1 from above, ensuring the accuracy of the material conveying path and preventing material spillage. A limiting block 3 is fixedly connected inside the discharge pipe 2. The limiting block 3 has a robust structure and is firmly installed, used to position the connecting cylinder 4, ensuring that the connecting cylinder 4 will not shift after installation, laying a stable foundation for the subsequent installation of related components of the steam pipeline. The connecting cylinder 4 is fixedly connected inside the limiting block 3. The connecting cylinder 4 has a straight body and a smooth interior, providing precise guiding space for the sliding of the sealing assembly, ensuring the stability of the sealing assembly during movement.
[0032] The connecting cylinder 4 has an internal sliding connection with a sealing assembly for engagement. This assembly includes a sealing cylinder 5 with a smooth, flat wall for easy sliding. An externally fixed limiting ring 6 is fixedly connected to the sealing cylinder 5. The regular annular structure of the limiting ring 6 allows for accurate engagement with the connecting ring 9, providing positioning and sealing assistance. Two sealing rings 7 are also fixedly connected to the external limiting ring 6. These sealing rings 7 are soft and elastic, fitting tightly against the limiting ring 6. When engaged with the sealing groove 10, they effectively prevent steam leakage, ensuring the sealing performance of the steam pipeline.
[0033] Reference Figures 3 to 4As shown, the outer part of the sealing ring 7 engages with the inner part of the sealing groove 10. The sealing ring 7 is made of rubber. A connecting cylinder 2 8 is slidably connected to the outer part of the sealing assembly. The inner space of the connecting cylinder 2 8 is used to install the steam generator 16. Its cylinder body is adapted to the connecting cylinder 1 4, providing a stable space for steam generation and transportation. Connecting rings 9 are fixedly connected to the outer parts of both the connecting cylinder 1 4 and the connecting cylinder 2 8. The ring surface of the connecting ring 9 is flat and in close contact with the limiting ring 6. On the one hand, it helps to fix the sealing assembly, and on the other hand, it provides a support point for the installation of the retaining ring 1 11 and retaining ring 2 13. The outer part of the connecting ring 9 is in contact with the outer part of the limiting ring 6. The outer part of the sealing cylinder 5 is slidably connected to the inner part of the connecting ring 9. A sealing groove 10 is opened on the outer part of the connecting ring 9. The groove of the sealing groove 10 is regular in shape and of moderate depth, which fits tightly with the sealing ring 7 to enhance the sealing effect.
[0034] Reference Figure 3 As shown, a limiting fastening assembly is installed externally on the sealing assembly. This fastening assembly includes a retaining ring 11. The retaining ring 11 has a flexible engagement structure, allowing it to rotate around the sealing assembly for easy installation and disassembly. A rotating block 12 is rotatably connected externally to the retaining ring 11. The rotating axis of the rotating block 12 is precise, ensuring smoother connection and rotation between the retaining ring 11 and retaining ring 13. The retaining ring 13 is rotatably connected internally to the rotating block 12. The retaining ring 13 works in conjunction with the retaining ring 11 to secure the sealing assembly and the connecting ring 9. Connecting blocks 14 are fixedly connected externally to both retaining rings 11 and 13. The robust structure of the connecting blocks 14 provides a stable foundation for the installation of bolts 15. The tightening action of the bolts 15 enhances the securing effect of the retaining rings 11 and 13 on the sealing assembly. Bolts 15 are threadedly connected internally to the connecting blocks 14.
[0035] Reference Figure 1 and Figure 5As shown, a steam generator 16 is fixedly connected inside the connecting cylinder 2 8. The steam generator 16 is used to generate steam. It is firmly installed and can work stably, providing a source for steam transportation. Two arc-shaped mounting blocks 17 are fixedly connected inside the connecting cylinder 2 8. The arc-shaped surfaces of the mounting blocks 17 are adapted to the rotating pipe 18. When the rotating pipe 18 rotates to the position of cutting off steam, the arc-shaped mounting blocks 17 can contact the rotating pipe 18, restricting its continued rotation and ensuring the accuracy and stability of the cutting-off operation. The rotating pipe 18 is rotatably connected to the adjacent side of the two arc-shaped mounting blocks 17. The rotating pipe 18 rotates flexibly and can accurately control the connection and cut-off state of the steam channel when rotating inside the connecting cylinder 2 8. The outside of the rotating pipe 18 is rotatably connected to the inside of the connecting cylinder 2 8, and the outside of the conveying pipe 19 is rotatably connected to the inside of the connecting cylinder 2 8. The conveying pipe 19 is fixedly connected inside the rotating pipe 18. The conveying pipe 19 is used to transport steam. Its connection with the rotating pipe 18 is tight, ensuring the sealing and smooth flow of steam during transportation. The external fixed connection of the conveying pipe 19 is a connecting post 20, which provides a connection point for the installation of the gear 24 and the limiting plate 25, so that the power assembly can accurately drive the rotating pipe 18 to rotate.
[0036] The connecting cylinder 28 is externally fixedly connected to a power component for driving. The power component includes a cylinder 21. The cylinder body of the cylinder 21 is firmly installed and can stably output power to drive the push rod 22 to extend and retract. The cylinder 21 is externally fixedly connected to the outside of the connecting cylinder 28. The drive end of the cylinder 21 is fixedly connected to the push rod 22. The push rod 22 is straight and tightly connected to the cylinder 21, which can accurately transmit the power of the cylinder 21 and drive the rack plate 23 to move. A rack plate 23 is fixedly connected to the outside of the push rod 22. The teeth of the rack plate 23 are clear and mesh tightly with the gear 24. Under the drive of the push rod 22, the gear 24 can be precisely driven to rotate. The outside of the rack plate 23 and the outside of the gear 24 are meshed. The outside of the gear 24 is fixedly connected to the outside of the limiting plate 25. The gear 24 is fixedly connected to the outside of the connecting column 20. The limiting plate 25 is also fixedly connected to the outside of the connecting column 20. The connection between the gear 24 and the connecting column 20 is firm. Under the drive of the rack plate 23, the rotating tube 18 is driven to rotate. The limiting plate 25 can play a limiting role when the rotating tube 18 rotates, ensuring the accuracy of the rotation angle of the rotating tube 18 and realizing the precise cut-off of steam.
[0037] Working principle: The chute pipe 1 is mainly used for material conveying. The discharge pipe 2 is connected to the chute pipe 1 and is used to guide the material into the chute pipe 1. The cylinder 21 is fixed on the support structure, and the push rod 22 is connected to the piston of the cylinder 21. The rack plate 23 is installed at the end of the push rod 22, and the gear 24 meshes with the rack plate 23. The gear 24 is installed on the rotating pipe 18. When it is necessary to cut off the steam conveying, the cylinder 21 is activated, and the piston of the cylinder 21 pushes the push rod 22 to extend, and the push rod 22 drives the rack plate 23 to move. Since the rack plate 23 meshes with the gear 24, the movement of the rack plate 23 will drive the gear 24 to rotate, thereby causing the rotating pipe 18 to rotate. After the rotating pipe 18 rotates to a certain angle, the internal channel of the connecting cylinder 2 8 is no longer connected to the channel of the conveying pipe 19, thereby achieving the cut-off of steam. When the rotating pipe 18 rotates to the predetermined cut-off position, the arc-shaped mounting block 17 can contact the rotating pipe 18 to limit the rotation of the rotating pipe 18, ensuring the accuracy and stability of the steam cut-off.
[0038] When installing and connecting connecting cylinder 4 and connecting cylinder 8, in order to ensure their sealing performance, firstly, one end of sealing cylinder 5 is slid inside connecting cylinder 4, and then the other end of sealing cylinder 5 is slid inside connecting cylinder 8. Then, the connecting rings 9 on the outside of connecting cylinder 4 and connecting cylinder 8 are brought into contact with the limiting ring 6, and the sealing ring 7 is engaged inside the sealing groove 10 for initial sealing. Then, the retaining rings 11 and 23 are rotated outside the limiting ring 6 and connecting ring 9 and tightened by the connecting block 14 and bolt 15 for secondary sealing, thereby preventing steam leakage from the connection.
[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
