Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, and in particular to a pipeline desalination device. Background Technology

[0002] In industrial production, municipal water supply, and domestic water purification, water desalination is a crucial step in ensuring water quality and meeting specific process requirements. Pipeline desalination equipment based on reverse osmosis technology is widely used to remove impurities such as ions, organic matter, and microorganisms from water due to its high treatment efficiency and relatively low energy consumption. Currently available pipeline desalination equipment typically consists of a tubular membrane housing, an internal reverse osmosis membrane, and end caps for sealing the membrane housing openings. To ensure a tight seal during operation and prevent the mixing of raw water and desalinated product water from affecting the desalination effect, the end caps in existing equipment are usually designed to be slightly larger than the inner wall size of the membrane housing, achieving a tight seal through an interference fit.

[0003] However, this sealed design brings significant inconvenience to equipment maintenance. During the long-term use of pipeline desalination equipment, the reverse osmosis membrane needs to be replaced regularly to maintain stable desalination efficiency. The prerequisite for replacing the reverse osmosis membrane is to disassemble and reassemble the end cap at the membrane housing opening. Due to the interference fit between the end cap and the inner wall of the membrane housing, the disassembly and reassembly process is often very difficult. Operators often need to use tools to forcibly disassemble and reassemble the end cap by knocking, pulling, etc. Such violent disassembly and reassembly methods can easily cause physical damage to the edge and sealing surface of the end cap, resulting in problems such as deformation and cracks. When the damaged end cap is reinstalled, it cannot form a tight fit with the inner wall of the membrane housing, directly destroying the original sealing structure of the equipment. This not only causes the risk of water leakage, but also allows untreated raw water to seep into the desalination permeate, seriously affecting the desalination efficiency and water quality. Therefore, this application proposes a pipeline desalination device. Utility Model Content

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] Please see Figures 1-6 This utility model provides a technical solution: a pipeline desalination device, including a membrane housing 11, which is configured as a tubular structure with an opening at the left end. A reverse osmosis membrane 21 is inserted into the membrane housing 11 from the left end. An end cap 22 is interference-fitted into the opening at the left end of the membrane housing 11. Two connecting rings 221 are fixedly installed on the left side of the end cap 22. A shaft inserted into the left end of the reverse osmosis membrane 21 is provided on the right side of the end cap 22. Four sets of horizontally arranged guide rods 13 are arranged in a circular array on the left side of the outer wall of the membrane housing 11. A movable component covering the left end of the membrane housing 11 is sleeved on the four guide rods 13. Between the movable component and the two connecting rings 221 on the left side of the end cap 22... Each component is equipped with a top pressure assembly 4, and a base 15 is located below the membrane housing 11. Support blocks connected to the bottom of the membrane housing 11 are located at both ends and the middle of the top of the base 15. A drive assembly connected to the moving assembly is installed on the base 15. Through the combination of the tubular membrane housing 11, the insertable reverse osmosis membrane 21, the interference-fit end cap 22, the guide rod 13, the moving assembly, the top pressure assembly 4, the base 15 and the drive assembly, a complete and coordinated desalination system is formed. Compared with traditional equipment, its structural design lays the foundation for convenient disassembly and assembly and stable operation. The connection between the drive assembly and the moving assembly provides power support for the disassembly and assembly of the end cap 22, solving the problem that the disassembly and assembly of the end cap 22 of traditional equipment relies on manual force.

[0019] like Figure 1 and Figure 2 As shown, an inlet pipe 12 is fixedly connected to the top of the membrane housing 11, and the connection between the inlet pipe 12 and the membrane housing 11 is located between the reverse osmosis membrane 21 and the end cap 22, so that the raw water is accurately delivered to the front end of the reverse osmosis membrane 21, ensuring that the raw water can fully contact the reverse osmosis membrane 21 and then be discharged from its right end, thereby improving the desalination efficiency.

[0020] like Figure 1 , Figure 3and Figure 5 As shown, the moving assembly includes a collar 31, a connecting plate 32, and a flipping plate 33. The collar 31 is sleeved on the outside of the membrane housing 11. Four integral guide blocks 311 are arranged in a circular array on the outer wall of the collar 31. The four guide blocks 311 are movably sleeved on four guide rods 13. Two sets of connecting plates 32 are provided, with the two sets of connecting plates 32 located on both sides of the membrane housing 11 and connected to the left side of the collar 31. Fixed shafts 321 are installed on the outer side of the left end of each of the two connecting plates 32. Two sets of flipping plates 33 are provided. The flipping plates 33 are L-shaped, with one end of the vertical part of each of the two flipping plates 33 hinged to the two fixed shafts 321. The horizontal and vertical axes of the two flipping plates 33 are... The moving component is located at the left end of the membrane housing 11 and is connected to it. The two flip plates 33 are equipped with locking plugs at their connecting ends. The collar 31 moves smoothly along the membrane housing 11 through the cooperation of the guide block 311 and the guide rod 13, ensuring accurate adjustment of the moving component position. The connecting plate 32 connects the collar 31 and the flip plate 33. The L-shaped flip plate 33 can rotate around the fixed axis 321. After docking, it can cover the left end of the membrane housing 11 and is fixed with the locking plug. This flip-able and lockable structural design makes it easy for operators to open the moving component to replace the reverse osmosis membrane 21 or maintain the equipment. It has high operational flexibility and can effectively protect the end cap 22 and the left end of the reverse osmosis membrane 21 when the equipment is running.

[0021] like Figure 3 and Figure 5 As shown, the locking plug includes two fixing blocks 331 and bolts 332. The two fixing blocks 331 are respectively fixedly installed at the ends of the two flip plates 33 away from the connecting plate 32, and the two fixing blocks 331 are symmetrically distributed vertically. The bolts 332 are vertically inserted between the two fixing blocks 331. The bolts 332 vertically inserted into the two fixing blocks 331 can lock the docking ends of the two flip plates 33. The locking and unlocking operations are convenient and can quickly realize the closing and opening of the moving components. After unlocking, the flip plate 33 can rotate around the fixed shaft 321, which can avoid affecting the disassembly and replacement of the reverse osmosis membrane 21 at the left end of the membrane shell 11.

[0022] like Figure 3 and Figure 5As shown, both flip plates 33 have through holes 333 on their horizontal sections. Two sets of pressing components 4 are respectively inserted between the corresponding through holes 333 and the connecting ring 221 on the left side of the end cap 22. The pressing component 4 includes a screw 41, a nut 42, and a baffle 43. Both ends of the screw 41 are threaded. The right end of the screw 41 is threaded into the connecting ring 221, and the left end of the screw 41 passes through the through hole 333 on the corresponding flip plate 33. The nut 42 is threaded to the left end of the screw 41 and abuts against the left side of the horizontal section of the flip plate 33. The baffle 43 is fixed. The screw is fixedly mounted on the screw 41 and abuts against the right side of the horizontal part of the flip plate 33. The right end of the screw 41 is threaded into the connecting ring 221, and the left end passes through the through hole 333 and is fixed with the nut 42. With the help of the baffle 43, the flip plate 33 is clamped and fixed from both sides. The screw 41 realizes the connection between the flip plate 33 and the end cover 22. With the help of the drive component, the horizontal drive of the moving component is realized, so as to realize the smooth disassembly and assembly of the end cover 22 and the left opening of the membrane shell 11, ensuring the sealing performance, avoiding the damage to the end cover 22 caused by traditional violent disassembly and assembly, and extending the service life of the end cover 22.

[0023] like Figure 5 and Figure 6 As shown, limit plates are provided on both sides of the inner wall of the through hole 333, and limit grooves 411 are provided on both sides of the left end of the screw 41. When the screw 41 is inserted into the through hole 333, the limit grooves 411 on both sides of the left end of the screw 41 respectively engage with the corresponding limit plates. The limit plates on the inner wall of the through hole 333 and the limit grooves 411 on the left end of the screw 41 engage with each other, which can limit the rotation of the screw 41 and prevent the screw 41 from rotating with the nut 42 when the tightening force is adjusted by turning the nut 42 or when the top pressure assembly 4 is disassembled and installed. This ensures the connection stability between the screw 41 and the connecting ring 221, ensures the accurate control of the tightening force of the top pressure assembly 4 on the end cover 22, and also makes it easier for operators to quickly align the screw 41 with the through hole 333 and insert it, thus improving the installation efficiency of the top pressure assembly 4.

[0024] like Figure 1 and Figure 4As shown, the drive assembly includes a connecting frame 51, a slider 52, and a hydraulic rod 53. The left half of the top of the base 15 has a groove 151, and the right end of the groove 151 has a storage slot. The connecting frame 51 is U-shaped, and both ends of the connecting frame 51 are fixedly connected to the bottom of two connecting plates 32. The slider 52 is fixedly installed at the bottom of the connecting frame 51 and located in the groove 151. The hydraulic rod 53 is installed in the storage slot, and the telescopic end of the hydraulic rod 53 extends into the groove 151 and connects with the slider 52. The connecting frame 51 of the drive assembly connects the two connecting plates 32 into one unit. The slider 52 cooperates with the groove 151 to provide guidance for the movement of the moving assembly. The hydraulic rod 53 serves as a power source, and its telescopic end pushes the slider 52 to drive the moving assembly to move along the guide rod 13. The hydraulic drive method provides stable and controllable power, enabling the moving assembly to move smoothly and accurately. Then, through the top pressing assembly 4, the end cover 22 is moved smoothly to complete the disassembly and assembly of the end cover 22, reducing the labor intensity of the operator.

[0025] like Figure 1 As shown, anti-detachment plates 14 are installed on both sides of the left end of the membrane housing 11. The two connecting plates 32 in the moving assembly pass through the two anti-detachment plates 14 respectively. The anti-detachment plates 14 on both sides of the left end of the membrane housing 11 can constrain the connecting plates 32 in the moving assembly, increase the stability of the connecting plates 32 when moving, and improve the safety and reliability of the overall operation of the equipment.

[0026] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
