Technical Field

[0001] The utility model relates to the technical field of conveying pipelines, in particular to a nitric acid solution conveying pipeline. Background Technique

[0002] Nitric acid is a strong acid and is corrosive to most metal and non-metal materials. Therefore, materials with corrosion resistance are usually selected for conveying pipelines, such as stainless steel, special alloys (such as Hastelloy), polymers (such as polytetrafluoroethylene), etc. When producing nitric acid solution, a conveying pipeline is needed to convey it, and when the conveying pipeline is in use, it needs to be installed and connected for convenient use.

[0003] The existing authorized publication number is CN219755542U3, which discloses a nitric acid solution conveying pipeline, including a bottom box and a belt. The center of the bottom of the inner cavity of the bottom box is rotatably connected with a threaded rod through a bearing. A threaded sleeve is threadedly connected to the outer surface of the threaded rod. A driving mechanism is arranged on the right side of the inner cavity of the bottom box. The top of the threaded sleeve is fixedly connected with a support frame, and a pipeline body is arranged in the inner cavity of the support frame.

[0004] Although the above device can drive the threaded rod to rotate by setting a turntable, a rotating shaft, a driving pulley, a belt and a driven pulley, and then drive the threaded sleeve and the support frame to move up and down to adjust the support height of the support frame so that it can be suitable for different terrains, since the connection of the pipeline must be composed of the docking of multiple conveying pipelines, the above device does not set a certain connection mechanism at the connection. Since the pipeline also needs to be used for a long time, in order to ensure its service life, we hereby propose a nitric acid solution conveying pipeline. Content of the Utility Model

[0014] (1) By rotating the rotating bolt arranged on the surfaces of the main conveying pipe and the docking secondary pipe of the utility model, the clamping block at the top end of the rotating bolt is clamped with the fixing block. Then, rotate the column located above the clamping block. The column will drive the rotating rod on its front surface, so that the limiting block at the lower end of the rotating rod completes displacement on the clamping block until it is clamped with the clamping groove opened at the upper end of the fixing block.

The bottom end of the inner wall of the clamping groove is rotatably connected with a fixing plate 29.

[0024] One end of the rotating bolt 23 away from the limit ring 21 is fixedly connected with a clamping block 25. The upper end of the clamping block 25 is rotatably connected with a limit plate 26. The front surface of the limit plate 26 is fixedly connected with a rotating rod 27. One end of the rotating rod 27 away from the limit plate 26 is fixedly connected with a limit block 28. The lower end of the limit block 28 is clamped with the upper end of the card slot. The periphery of the limit block 28 is rotatably connected with the fixing plate 29. By rotating the rotating bolt 23 arranged on the surfaces of the conveying main pipe 1 and the docking secondary pipe 11, the clamping block 25 at the top end of the rotating bolt 23 is engaged with the fixing block 24. Then, rotate the column 26 above the clamping block 25. The column 26 will drive the rotating rod 27 on its front surface, so that the limit block 28 at the lower end of the rotating rod 27 completes displacement on the clamping block 25 until it is clamped with the card slot opened at the upper end of the fixing block 24. Then, rotate the card slot 29 to complete the limit fixation of the conveying main pipe 1 and the docking secondary pipe 11.

[0025] A support mechanism 3 is arranged on the front surface of the support plate 12. The support mechanism 3 includes a support groove 32 opened on the front surface of the support plate 12. The bottom end of the inner wall of the support groove 32 is rotatably connected with a rotating shaft 31.

[0026] One end of the rotating shaft 31 away from the inner wall of the support groove 32 is fixedly connected with a rotating plate 33. A limit groove 34 is opened on the front surface of the rotating plate 33. The number of the rotating shafts 31 is set to two. The two rotating shafts 31 are symmetrically arranged about the center of the limit ring 21. By rotating the rotating shaft 31 on the front surface of the support plate 12, the rotating shaft 31 will drive the rotating plate 33 at its top end to rotate, so that the limit groove 34 opened on the rotating plate 33 is clamped with the surface of the conveying main pipe 1, thus completing the support and limit of the conveying pipeline.

[0027] A rotating mechanism 4 is arranged on the surface of the conveying main pipe 1. The rotating mechanism 4 includes a rotating rod 43 that rotates through the conveying main pipe 1. A connecting block 41 is fixedly connected to the top surface of the rotating rod 43.

[0028] One end of the connecting block 41 away from the rotating rod 43 is fixedly connected with a rotating valve 42. There is a storage box 44 inside the inner wall of the conveying main pipe 1.

One end of the rotating rod 43 away from the rotary valve 42 is fixedly connected with the extension plate 46. The storage box 44 is located inside the main conveying pipe 1. One end of the extension plate 46 away from the connecting plate 45 is clamped with the inner wall of the main conveying pipe 1. A connecting ring 13 is fixedly connected at the internal connection of the main conveying pipe 1 and the docking secondary pipe 11. When detection is required or the pipeline needs to be closed, just rotate the rotary valve 42 on the front of the main conveying pipe 1. The rotary valve 42 will drive the rotating rod 43 to rotate, thereby pushing the extension plate 46 inside the connecting plate 45 to extend, thus sealing the pipeline, facilitating maintenance or dealing with accidents, and extending the service life of the device.

[0030] The present utility model provides a nitric acid solution conveying pipeline, and the specific working principle is as follows:

[0031] During use, the user needs to first clamp the main conveying pipe 1 and the docking secondary pipe 11. Then rotate the rotating shaft 31 on the front of the support plate 12. The rotating shaft 31 will drive the rotating plate 33 at its top to rotate, so that the limiting groove 34 opened on the rotating plate 33 is clamped with the surface of the main conveying pipe 1, thus completing the support and limitation of the conveying pipeline. Then rotate the rotating bolt 23 arranged on the surfaces of the main conveying pipe 1 and the docking secondary pipe 11 again, so that the clamping block 25 at the top of the rotating bolt 23 is clamped with the fixing block 24. Then rotate the column 26 above the clamping block 25. The column 26 will drive the rotating rod 27 on its front, so that the limiting block 28 at the lower end of the rotating rod 27 is displaced on the clamping block 25 until it is clamped with the clamping groove opened at the upper end of the fixing block 24. Then rotate the clamping groove 29 to complete the limiting and fixing of the main conveying pipe 1 and the docking secondary pipe 11. At the same time, a connecting ring 13 is also fixedly connected at the internal connection of the main conveying pipe 1 and the docking secondary pipe 11. When detection is required or the pipeline needs to be closed, just rotate the rotary valve 42 on the front of the main conveying pipe 1. The rotary valve 42 will drive the rotating rod 43 to rotate, thereby pushing the extension plate 46 inside the connecting plate 45 to extend, thus sealing the pipeline, facilitating maintenance or dealing with accidents, and extending the service life of the device.
