Description

Technical Field

[0001] This utility model relates to the technical field of large-scale air separation units, specifically a sealing and leak-proof structure for large-scale air separation units in fertilizer plants. Background Technology

[0002] Large-scale air separation units are large industrial equipment used to separate air into gases such as oxygen and nitrogen. They are widely used in chemical, metallurgical, and energy fields. When using large-scale air separation units, leak-proof structures must be used to seal their connections.

[0003] Existing leak-proof structures include a flexible sleeve, a connecting end, and a clamp. The large-diameter end of the flexible sleeve is connected to the air separation unit's connection port via the clamp, while the small-diameter end is bolted to other external connectors via the connecting end, thus sealing the air separation unit connection. However, the connection between the connecting end and the external connector is heavy, and a connecting pipe is connected below the connector, causing the connecting pipe to be subjected to significant gravity. After long-term use, the support of the connecting pipe will sag. Therefore, a leak-proof structure with auxiliary support is needed to reduce the weight of the connecting pipe.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0017] Please see Figures 1-5 As shown, this utility model is a sealing and leak-proof structure for a large air separation unit in a fertilizer plant, comprising: Leakage prevention component, including soft sleeve 12; the lower end of soft sleeve 12 is fitted onto the air separation unit connection port; The leak prevention assembly also includes a connector 13, a vertical rod 14, and a connecting tube 15; the connector 13 is screwed to the outside of the upper connecting end of the soft sleeve 12, the vertical rod 14 is fixed to the bottom end of the connector 13, and the connecting tube 15 is fixed to the bottom end of the vertical rod 14, with one end fixedly connected to the lower side of the air separation unit. The soft sleeve 12 is used for sealing the connection between the air separation unit and other external equipment. The connector 13 is used for connecting the air separation unit with other equipment. The vertical rod 14 is used for connecting the connector 13 and the connecting pipe 15. The connecting pipe 15 is used to transport the material inside the air separation unit.

[0018] The support assembly includes a fixed rod 21, a support frame 22, an auxiliary support plate 23, and diagonal braces 24. The fixed rod 21 is fixed below the air separation unit connection port, the support frame 22 is located at the top of the fixed rod 21, the auxiliary support plate 23 is fixed at the center of one end of the fixed rod 21, and the diagonal braces 24 are located on both sides of the bottom end of the fixed rod 21. The fixed rod 21 is used to connect the support frame 22. The support frame 22 is used to place the connection end of the soft sleeve 12 and the connection point of the connector 13. The auxiliary support plate 23 provides auxiliary support for the connecting pipe 15. The diagonal brace 24 is used to support the fixed rod 21 and the support frame 22.

[0019] The fixing rod 21 is located below the connecting pipe 15. The inside of the support frame 22 is intersected with one end of the connecting pipe 15. A set of fixing blocks 25 are fixedly connected to both sides of the bottom end of the fixing rod 21. The upper end of the diagonal brace 24 is snapped between the inner sides of each set of fixing blocks 25, and a damping shaft 26 is movably connected at the snapping point. The fixing block 25 is used for the snap-fit ​​of the upper end of the diagonal brace 24, and the damping shaft 26 is used for the connection between the diagonal brace 24 and the fixing block 25 and for the rotation of the diagonal brace 24.

[0020] The top of the fixed rod 21 has two insertion slots 27 on both sides, and the insertion rod 28 is inserted into the insertion slot 27. The top of the insertion rod 28 is fixedly connected to the bottom two sides of the support frame 22. The auxiliary support plate 23 is located below the connecting pipe 15. The lower end of the diagonal brace 24 extends into the air separation unit. The air separation unit has a slot 29 at the insertion point of the diagonal brace 24. A groove 221 is provided on one side of the top of the support frame 22. The groove 221 is engaged with the connection point of the soft sleeve 12 and the connector 13. The insertion slot 27 and insertion rod 28 are used for the connection between the support frame 22 and the fixed rod 21. Inserting the insertion rod 28 into the insertion slot 27 connects the support frame 22 and the fixed rod 21 together. The slot 29 is used for the insertion of the lower end of the diagonal brace 24, so that the diagonal brace 24 supports the upper fixed rod 21 and the support frame 22 through diagonal support force. The groove 221 is used for the placement of the soft sleeve 12 connection end and the connector 13 connection point, so that the support frame 22 supports it.

[0021] Working principle: When the component is not in use, the soft sleeve 12 is not installed, and the bottom end of the diagonal brace 24 is attached to the fixed rod 21. When the component is in use, the soft sleeve 12 is connected to the connection port of the air separation unit through the clamp, and then the connecting end of the soft sleeve 12 is connected to the connector 13. The diagonal brace 24 is rotated by hand, so that the diagonal brace 24 rotates downward through the damping shaft 26 and the lower end of the diagonal brace 24 is inserted into the slot 29. Then, the connection between the soft sleeve 12 and the connector 13 is engaged with the groove 221, so that the support frame 22 supports the connection between the soft sleeve 12 and the connector 13 through the lower fixed rod 21 and the diagonal brace 24. The auxiliary support plate 23 is located below the connecting pipe 15, so that the auxiliary support plate 23 provides auxiliary support for the connecting pipe 15. This causes the fixed rod 21, the support frame 22 and the diagonal brace 24 to provide a second support rod for the connection between the soft sleeve 12 and the connector 13, thereby sharing the weight of the connecting pipe 15.

[0022] Please see Figures 1-4 As shown, this embodiment, based on the above embodiment, further includes: Protective components; The protective assembly includes an annular block 31, a spring 32, and a telescopic rod 33; the annular block 31 is fixed to one side of the support frame 22, the spring 32 and the telescopic rod 33 are both fixed to the center of the inner side of the annular block 31, and the telescopic rod 33 is located inside the spring 32; A protective block 34 is fixedly connected to the outer end of the spring 32 and the telescopic rod 33. The protective block 34 is located below the soft sleeve 12. The annular block 31 is used to connect the spring 32 and the telescopic rod 33. The spring 32 and the telescopic rod 33 are used to connect the protective block 34. The protective block 34 is used to protect the lower part of the soft sleeve 12. When the soft sleeve 12 expands, it will squeeze the protective block 34, causing the spring 32 and the telescopic rod 33 to contract. This allows the protective block 34 to protect the lower part of the soft sleeve 12 when it expands through the spring 32 and the telescopic rod 33, preventing the soft sleeve 12 from being affected by external factors below and thus failing to operate normally.

[0023] Working principle: When the component is not in use, the soft sleeve 12 is not affected by the air separation unit and expands. When the soft sleeve 12 is affected by the air separation unit and gradually expands, it will gradually squeeze the protective block 34. The squeezing force pushes the spring 32 and the telescopic rod 33 to contract, so that the protective block 34 moves towards the annular block 31 through the spring 32 and the telescopic rod 33, so that the protective block 34 protects the bottom of the soft sleeve 12 when it expands through the spring 32 and the telescopic rod 33.
