Description

Technical Field

[0001] This utility model relates to the field of air compressor waste heat recovery pipeline connection technology, specifically a quick connection connector for air compressor waste heat recovery pipeline. Background Technology

[0002] With the increasing global focus on energy conservation and emission reduction, waste heat recovery systems for air compressors have been widely used in the industrial sector. Air compressors generate a large amount of heat during operation. Through waste heat recovery systems, this heat can be used to preheat boiler feedwater, heat employee shower water, and even provide heating for workshops, greatly improving energy efficiency and reducing operating costs for enterprises.

[0003] In air compressor waste heat recovery systems, pipe connection joints are key components that significantly impact the system's operational stability and heat recovery efficiency. However, existing pipe connection joints generally use threaded connections, which are inconvenient for installation and disassembly.

[0004] According to the description in the quick-connect fitting for waste heat recovery pipeline of air compressor published on the patent website (authorization announcement number: CN210424103U), the quick-connect fitting for waste heat recovery pipeline of air compressor includes "fitting one, fitting two, mounting plate" etc., to realize the connection work.

[0005] Regarding the above description, the applicant believes the following issues exist:

[0006] The quick-connect fitting for the waste heat recovery pipeline of this air compressor uses a connector, a second connector, and a mounting plate to achieve the connection. When using this fitting, the second connector is inserted into the first connector, so that the lower side wall of the sealing ring abuts against the upper side wall of the folded edge, and the moving rod is pushed to one side of the mounting plate. This installation method not only makes it difficult to insert the second connector into the first connector, but also fixes it only by rotating the bolt, resulting in poor stability and failing to seal the connection between the two connectors. Therefore, this fitting needs to be improved. Utility Model Content

[0033] Please see Figure 1-6This utility model provides a technical solution: a quick connection connector for waste heat recovery pipeline of an air compressor, including a rotating ring 1, a connecting mechanism 2 provided on the inner side of the rotating ring 1, and a sealing mechanism 3 provided on the left side of the connecting mechanism 2;

[0034] The connecting mechanism 2 includes a sealing sleeve 22, which is fixedly connected to the inner side of the rotating ring 1.

The moving frame 28 is slidably connected to the inside of the fixing frame 23. A fixing block 29 is fixedly connected to the rear side of the moving frame 28. The fixing block 29 is inserted into the inside of the recovery tube body 25. A connecting frame 291 is fixedly connected to the front side of the moving frame 28. A limiting shaft 292 is fixedly connected to the rear side of the connecting frame 291. The limiting shaft 292 is inserted into the inside of the sealing ring 26.

[0035] The connecting sleeve 24 has an installation groove on its right side, and the recycling tube body 25 is slidably connected in the installation groove, which facilitates the installation of the recycling tube body 25 through the installation groove. The inner side of the sealing ring 26 is in contact with the right side of the connecting sleeve 24, and both the sealing ring 26 and the sealing sleeve 22 are made of heat-resistant and corrosion-resistant materials, which facilitates the sealing of the gap between the connecting sleeve 24 and the recycling tube body 25 through the sealing ring 26.

[0036] The fixing block 29 passes through the inside of the connecting sleeve 24. The connecting sleeve 24 and the recovery tube body 25 are respectively provided with fixing grooves, and the two fixing grooves correspond to each other. The fixing block 29 is inserted into the fixing groove, which facilitates the stability between the connecting sleeve 24 and the recovery tube body 25. The sealing ring 26 is provided with a limit groove, and the limit shaft 292 is inserted into the limit groove, which facilitates the limit of the sealing ring 26. The fixing frame 23, adjusting shaft 27, moving frame 28, fixing block 29, connecting frame 291 and limit shaft 292 are provided in two sets. The two sets of fixing frame 23, adjusting shaft 27, moving frame 28, fixing block 29, connecting frame 291 and limit shaft 292 are symmetrically distributed on the front and rear sides of the connector body 21, which facilitates the improvement of the stability of the recovery tube body 25 during installation by setting two sets.

[0037] Example 2

[0038] Please see Figure 1-6Furthermore, based on Embodiment 1, the sealing mechanism 3 further includes an insertion rod 31, which is inserted into the left side of the sealing sleeve 22. A limiting pin 32 is threadedly connected inside the insertion rod 31. A sealing seat 33 is fixedly connected to the left side of the insertion rod 31. The sealing seat 33 is slidably connected to the periphery of the connector body 21. A protective block 34 is fixedly connected to the right side of the sealing seat 33. The protective block 34 is inserted into the inside of the sealing sleeve 22. The limiting pin 32 passes through the inside of the sealing sleeve 22. Slots are respectively opened inside the sealing sleeve 22 and the insertion rod 31, and the two slots correspond to each other. The limiting pin 32 is threadedly connected to the slot. The inner side and the right side of the sealing seat 33 are in contact with the periphery of the connector body 21 and the left side of the sealing sleeve 22, respectively, so as to ensure the stability of the insertion rod 31 and the sealing seat 33 through the limiting pin 32.

[0039] The insert rod 31, the limiting pin 32, the sealing seat 33 and the protective block 34 are provided in two sets. The two sets of insert rod 31, limiting pin 32, sealing seat 33 and protective block 34 are symmetrically distributed on the left and right sides of the sealing sleeve 22, so that the comprehensiveness of the seal can be improved by setting two sets.

[0040] In actual operation, when this device is used, if it is necessary to quickly connect the external recovery pipe body 25 to the waste heat outlet pipe of the air compressor, first remove the sealing sleeve 22, insert the insertion rod 31 into the left side of the sealing sleeve 22, and insert the protective block 34 into the sealing sleeve 22. Then, fix the insertion rod 31 by the limit pin 32. After fixing, the sealing sleeve 22 can be re-threaded to the outside of the connector body 21, and the sealing seat 33 can be slidably connected to the outside of the connector body 21.

[0041] The threaded groove on the waste heat outlet pipe of the air compressor is aligned with the threaded groove on the connector body 21, so that the left side of the connector body 21 and the right side of the waste heat outlet pipe are in contact with each other. Under the action of the rotating ring 1, the sealing sleeve 22 is rotated, so that the sealing sleeve 22 is rotated to the position where the connector body 21 contacts the waste heat outlet pipe, which can fix it and achieve a sealing effect. Under the action of the sealing seat 33, the inner side of the sealing sleeve 22 can further seal the position where it contacts the outer side of the connector body 21 and the outer side of the air compressor waste heat outlet pipe, thus improving the sealing effect of the connection.

[0042] At this point, the sealing ring 26 can be slidably connected to the periphery of the recovery pipe body 25, and the recovery pipe body 25 can be slidably connected to the right side of the connecting sleeve 24. At the same time, the inner side of the sealing ring 26 and the right side of the connecting sleeve 24 are in contact with each other. Rotating the adjusting shaft 27 causes the moving frame 28 to move the fixing block 29, the connecting frame 291 and the limiting shaft 292. The fixing block 29 is inserted into the connecting sleeve 24 and the recovery pipe body 25 to fix them, and the limiting shaft 292 is inserted into the sealing ring 26. This allows for quick connection of the recovery pipe body 25, while the sealing ring 26 ensures the sealing effect at the connection between the recovery pipe body 25 and the connecting sleeve 24. It also facilitates installation and disassembly. The two sets of symmetrically distributed fixing frames 23, adjusting shaft 27 and other components fix the recovery pipe body 25 from the front and rear sides to ensure the stability of the fixation. This allows for quick connection between the air compressor and the recovery pipe body 25.
