Description

Technical Field

[0001] This utility model relates to the field of fluoropolymer-lined anti-corrosion storage tank technology, specifically to a pipeline connection structure for a fluoropolymer-lined anti-corrosion storage tank. Background Technology

[0002] Fluoroplastics are widely used in the chemical, pharmaceutical, and food industries, attracting considerable attention due to their excellent corrosion resistance. With the increasing demand for corrosion-resistant storage tanks in the industrial sector, fluoropolymer-lined storage tanks have gradually become the mainstream choice in the industry. Furthermore, with advancements in materials science and manufacturing technology, modern fluoropolymer-lined storage tanks now possess even higher corrosion resistance, better sealing, and a longer service life.

[0003] In industries such as chemical and pharmaceutical manufacturing, fluoropolymer-lined corrosion-resistant storage tanks are widely used to store various corrosive media. Existing methods for connecting fluoropolymer-lined corrosion-resistant storage tanks to external pipelines typically employ traditional threaded flange connections. This method requires operators to tighten multiple bolts one by one during installation, resulting in cumbersome and time-consuming steps and low installation efficiency. Furthermore, when disassembling, repairing, or replacing the pipeline, significant time and effort are needed to loosen each bolt, making disassembly and repair work even more difficult. Therefore, this paper proposes a new pipeline connection structure for fluoropolymer-lined corrosion-resistant storage tanks to address the aforementioned problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a pipeline connection structure for fluoropolymer-lined corrosion-resistant storage tanks, which has advantages such as high assembly and disassembly efficiency, and solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A pipeline connection structure for a fluoropolymer-lined corrosion-resistant storage tank includes a storage tank body, a top cover detachably connected to the top of the storage tank body, a storage tank pipeline fixedly connected to the outside of the storage tank body, and a first flange fixedly connected to the outside of the storage tank pipeline. A connecting pipeline is provided outside the first flange, and a second flange is fixedly connected to the outside of the connecting pipeline. A limiting structure for quick docking is provided outside the first flange and the second flange. An adjustment mechanism for moving the limiting structure is provided outside the storage tank body.

[0007] The limiting structure includes an adjusting rod disposed outside the storage tank body, a sleeve slidably connected to the outside of the adjusting rod, a movable plate fixedly connected to the bottom end of the sleeve, an abutment plate disposed outside the movable plate, and an insert rod extending into the inside of the first flange and the second flange fixedly connected to the outside of the abutment plate.

[0008] Furthermore, the adjusting rod has a plurality of adjusting holes inside, which are distributed at equal intervals inside the adjusting rod, and a limiting rod extending into the adjusting holes is inserted into the outside of the sleeve.

[0009] Furthermore, a plurality of elastic telescopic rods are fixedly installed between the movable plate and the abutment plate, and the plurality of elastic telescopic rods are arranged in a ring shape between the movable plate and the abutment plate.

[0010] Furthermore, both the first flange and the second flange have a limiting hole inside that matches the insertion rod, and the outer diameter of the insertion rod matches the inner diameter of the limiting hole.

[0011] Furthermore, the diameters of the first flange and the second flange are matched, and sealing gaskets are fixedly connected to opposite sides of both the first flange and the second flange.

[0012] Furthermore, the adjustment mechanism includes an installation box fixedly installed outside the storage tank body and a drive motor fixedly installed outside the installation box. A threaded rod is rotatably connected inside the installation box, and a threaded block is threadedly connected to the outside of the threaded rod. The adjustment rod is fixedly connected to the bottom of the threaded block.

[0013] Furthermore, a worm gear is fixedly mounted on the output shaft of the drive motor, and a worm wheel that meshes with the worm gear is fixedly mounted on the outside of the threaded rod.

[0014] Furthermore, the threaded block is externally fixedly connected to a slider extending into the interior of the mounting box, and the interior of the mounting box is provided with a sliding groove that matches the slider, and the slider and the sliding groove are slidably connected.

[0015] Compared with the prior art, this utility model provides a pipeline connection structure for a fluoropolymer-lined corrosion-resistant storage tank, which has the following advantages:

[0016] 1. The pipeline connection structure of this fluoropolymer-lined corrosion-resistant storage tank allows the adjusting mechanism to move the adjusting rod, which in turn moves the sleeve, moving plate, and abutment plate as a whole. By aligning the insertion rod with the limiting holes of the first and second flanges and inserting it, the two flanges can be quickly connected without the need to tighten multiple bolts one by one as in traditional threaded flange connections. This greatly saves installation time, enables rapid connection and disassembly of pipelines, and significantly improves installation efficiency and maintenance convenience.

[0017] 2. The pipeline connection structure of this fluoropolymer-lined corrosion-resistant storage tank allows for adjustment of the sleeve's position on the adjusting rod by inserting a limiting rod into the adjusting holes at different locations. This, in turn, adjusts the position of the insertion rod, accommodating flanges of various sizes and improving the structure's versatility and flexibility. Simultaneously, the limiting rod, once inserted into the adjusting hole, can fix the sleeve, preventing it from sliding freely during pipeline use and ensuring connection stability. During the insertion of the insertion rod into the flange, the elastic telescopic rod acts as a buffer, preventing damage to the flange due to excessive insertion force. Furthermore, when the pipeline experiences minor displacement due to temperature changes, vibration, or other factors during use, the elastic telescopic rod can deform elastically to compensate for these displacements, maintaining a tight connection between the insertion rod and the flange, enhancing the connection's sealing performance, and preventing media leakage.

[0022] 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.

[0023] Please see Figures 1 to 3The pipeline connection structure of a fluoropolymer-lined corrosion-resistant storage tank in this embodiment includes a storage tank body 1, a top cover 2 detachably connected to the top of the storage tank body 1, a storage tank pipeline 3 fixedly connected to the outside of the storage tank body 1, and a first flange 4 fixedly connected to the outside of the storage tank pipeline 3. A connecting pipeline 5 is provided on the outside of the first flange 4, and a second flange 6 is fixedly connected to the outside of the connecting pipeline 5. A limiting structure 7 for quick docking is provided on the outside of the first flange 4 and the second flange 6. An adjustment mechanism 8 for moving the limiting structure 7 is provided on the outside of the storage tank body 1.

[0024] The limiting structure 7 includes an adjusting rod 71 disposed outside the storage tank body 1. A sleeve 72 is slidably connected to the outside of the adjusting rod 71. A moving plate 74 is fixedly connected to the bottom end of the sleeve 72. An abutting plate 76 is disposed outside the moving plate 74. An insert rod 77 extending into the inside of the first flange 4 and the second flange 6 is fixedly connected to the outside of the abutting plate 76.

[0025] Specifically, the adjusting rod 71 has multiple adjusting holes 73 inside, which are distributed at equal intervals inside the adjusting rod 71. A limiting rod extending into the adjusting holes 73 is inserted into the outside of the sleeve 72. During pipe installation, the adjusting mechanism 8 moves the adjusting rod 71, thereby moving the sleeve 72, the moving plate 74, and the abutment plate 76 as a whole. The insertion rod 77 is then aligned with the limiting holes of the first flange 4 and the second flange 6 and inserted, quickly achieving the connection of the two flanges. Unlike traditional threaded flange connections, multiple bolts need to be tightened individually, significantly saving installation time and improving efficiency. Disassembly is simple and quick; the insertion rod 77 is simply pulled out, reducing the difficulty of disassembly and maintenance.

[0026] It should be noted that multiple elastic telescopic rods 75 are fixedly installed between the movable plate 74 and the abutment plate 76, arranged in a ring shape between them. During the insertion of the insertion rod 77 into the flange, the elastic telescopic rods 75 act as a buffer, preventing damage to the flange due to excessive insertion force. Simultaneously, when the pipeline experiences slight displacement due to temperature changes, vibration, or other factors during use, the elastic telescopic rods 75 can elastically deform to compensate for these displacements, maintaining a tight connection between the insertion rod 77 and the flange, enhancing the sealing performance, and preventing media leakage.

[0027] It is worth mentioning that both the first flange 4 and the second flange 6 have internal limiting holes that match the insert rod 77, and the outer diameter of the insert rod 77 matches the inner diameter of the limiting hole. The diameters of the first flange 4 and the second flange 6 are also matched, and sealing gaskets are fixedly connected to opposite sides of both the first flange 4 and the second flange 6. The matching limiting holes and the insert rod 77 ensure a tight fit between them, preventing relative displacement of the first flange 4 and the second flange 6 during connection, thus enhancing the stability of the connection. At the same time, the limiting holes also provide accurate positioning for the insert rod 77, ensuring that the insert rod 77 can be smoothly inserted, improving the efficiency and accuracy of installation.

[0028] Please see Figures 1 to 2 In this embodiment, the adjusting mechanism 8 includes a mounting box 81 fixedly installed outside the storage tank body 1 and a drive motor 82 fixedly installed outside the mounting box 81. A threaded rod 84 is rotatably connected inside the mounting box 81, and a threaded block 85 is threadedly connected to the outside of the threaded rod 84. An adjusting rod 71 is fixedly connected to the bottom of the threaded block 85. The drive motor 82 provides power for the movement of the adjusting rod 71, eliminating the need for manual operation and reducing the workload of operators. By controlling the forward and reverse rotation of the drive motor 82, the rotation direction and number of turns of the threaded rod 84 can be precisely controlled, thereby precisely controlling the movement distance of the threaded block 85 and the adjusting rod 71. This allows the insertion rod 77 to accurately insert into or remove from the limiting hole of the flange, improving the accuracy and convenience of operation.

[0029] The drive motor 82 has a worm gear 83 fixedly mounted on its output shaft, and a worm wheel 86 meshing with the worm gear 83 is fixedly mounted on the outside of the threaded rod 84. The transmission between the worm gear 83 and the worm wheel 86 is self-locking; when the drive motor 82 stops rotating, the worm wheel 86 cannot drive the worm gear 83 to rotate, thus ensuring that the threaded rod 84 will not reverse on its own. This allows the adjusting rod 71 and the insertion rod 77 to remain stably in their current positions, ensuring the stability of the pipe connection. Simultaneously, the stable transmission ratio of the worm gear 83 and the worm wheel 86 enables precise speed reduction, making the movement speed of the adjusting rod 71 uniform and controllable.

[0030] Specifically, the threaded block 85 is externally fixedly connected to a slider that extends into the mounting box 81. The mounting box 81 has a groove inside that matches the slider, and the slider and the groove are slidably connected.

[0031] The working principle of the above embodiments is as follows:

[0032] In use, align the first flange 4 of the storage tank pipeline 3 and the second flange 6 of the connecting pipeline 5, ensuring the limiting holes are aligned. Start the drive motor 82 in the adjusting mechanism 8. The drive motor 82 drives the threaded rod 84 to rotate via the worm gear 83 and worm wheel 86. The rotation of the threaded rod 84 causes the threaded block 85 to move inward. The threaded block 85 drives the moving plate 74 to move inward via the adjusting rod 71. The moving plate 74 pushes the abutment plate 76 via the elastic telescopic rod 75, allowing the insertion rod 77 to be inserted into the limiting holes of the first flange 4 and the second flange 6, achieving quick docking. In disassembly, start the drive motor 82, causing the threaded rod 84 to rotate in the opposite direction, driving the threaded block 85 to move outward. The adjusting rod 71 drives the moving plate 74 to move outward via the threaded block 85. The elastic telescopic rod 75 retracts, and the abutment plate 76 pulls the insertion rod 77 out of the limiting hole, separating the storage tank pipeline 3 and the connecting pipeline 5, completing the disassembly.

Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply.
