Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, and in particular to a corrosion-resistant sealing connection device for reverse osmosis membranes. Background Technology

[0002] Reverse osmosis (RO) technology, as a highly efficient membrane separation technology, has become one of the core technologies in the water treatment field due to its excellent desalination and purification performance. It is widely used in municipal water supply, industrial pure water production, seawater desalination, and environmental water treatment. The RO membrane module is the core component of the RO system, and its sealing performance directly determines the system's separation efficiency, operational stability, and service life. In practical applications, the RO membrane module needs to achieve reliable connection with the membrane housing and adjacent membrane elements through a sealed connection structure. This must prevent cross-contamination between raw water and product water, which could lead to water pollution, and also ensure the system's sealing performance under high-pressure operation to avoid media leakage.

[0003] Currently, most of the corrosion-resistant sealing connection devices for reverse osmosis membranes on the market consist of a central pipe with a sealing ring that directly connects the two ends of the reverse osmosis membrane. This requires hammering during installation, which makes the installation process rather troublesome. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a reverse osmosis membrane corrosion-resistant sealing connection device, which aims to improve the problem of the relatively troublesome installation of the reverse osmosis membrane corrosion-resistant sealing connection device.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A corrosion-resistant sealing connection device for reverse osmosis membranes includes an outer filter tube, a delivery pipe fixedly connected to the outside of the outer filter tube, a water supply pipe fixedly connected to one end of the delivery pipe, a filter chamber inside the outer filter tube, a first reverse osmosis membrane slidably connected inside the filter chamber, a second reverse osmosis membrane slidably connected inside the filter chamber, a fixing component installed at one end of the first reverse osmosis membrane, the fixing component including a first threaded rail, the threaded rail being fitted onto one end of the fixing component, a second threaded rail being opened at one end of the second reverse osmosis membrane, a connecting pipe threadedly connected to the outside of the second threaded rail, and one end of the connecting pipe being threadedly connected to the outside of the first threaded rail.

[0006] Preferably, the connecting pipe is externally fixedly connected to a limiting block one, the connecting pipe is externally fixedly connected to a sealing ring one, and the connecting pipe is externally fixedly connected to a limiting block two.

[0007] Preferably, a second sealing ring is fixedly connected to the outside of the connecting pipe, and an outer fixing ring is slidably connected to the outside of the connecting pipe. The inner thread of the outer fixing ring is connected to the outside of the threaded rail.

[0008] Preferably, the connecting pipe is slidably connected to an outer fixing ring two, and the inner thread of the outer fixing ring two is connected to the inside of the threaded rail two.

[0009] Preferably, the filter outer tube has a fixing groove inside.

[0010] Preferably, the fixing groove is internally threaded with a screw, and one end of the screw is rotatably connected to a pressing block.

[0011] Preferably, a sealing ring three is slidably connected to the outside of the extrusion block one, and the sealing ring three is externally connected to one end of the reverse osmosis membrane two.

[0012] Preferably, one end of the sealing ring three is slidably connected to the compression block two.

[0013] This utility model has the following beneficial effects: 1. In this utility model, when it is necessary to install the connecting device, the rotating connecting tube is fixed at both ends of the reverse osmosis membrane one and the reverse osmosis membrane two, the sealing ring one and the sealing ring two seal the interface after connection, and then the outer fixing ring one and the outer fixing ring two are rotated to fix the reverse osmosis membrane one and the reverse osmosis membrane two from the outside, so as to achieve the purpose of quickly installing the connecting device.

[0014] 2. In this utility model, when it is necessary to fix the reverse osmosis membrane inside the filter outer tube, the first extrusion block and the second extrusion block are rotated to drive the screw to rotate inside the fixing groove. Finally, the sealing ring three is squeezed on the outside of the filter outer tube and the second reverse osmosis membrane. The first extrusion block forms a restriction on the outside of the filter outer tube and the second reverse osmosis membrane, thereby achieving the purpose of fixing the reverse osmosis membrane.

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] Reference Figures 1-3 The present invention provides an embodiment of a reverse osmosis membrane corrosion-resistant sealing connection device, comprising an outer filter tube 1, a conveying pipe 2 fixedly connected to the outside of the outer filter tube 1, a water supply pipe 3 fixedly connected to one end of the conveying pipe 2, a filter chamber 4 opened inside the outer filter tube 1, a reverse osmosis membrane 5 slidably connected inside the filter chamber 4, a reverse osmosis membrane 6 slidably connected inside the filter chamber 4, a fixing component 7 installed at one end of the reverse osmosis membrane 5, the fixing component 7 including a threaded rail 8, the threaded rail 8 being sleeved on one end of the fixing component 7, a threaded rail 9 opened at one end of the reverse osmosis membrane 6, a connecting pipe 10 threadedly connected to the outside of the threaded rail 9, and one end of the connecting pipe 10 threadedly connected to the outside of the threaded rail 8.

[0019] Specifically, the outer filter tube 1 provides filtration space for the filtration device and also houses the first reverse osmosis membrane 5 and the second reverse osmosis membrane 6. The delivery pipe 2 is used to transport the wastewater or other water quality that needs to be filtered. The water supply pipe 3 is used to integrate and connect all the filtration components. The filter chamber 4 provides a place for wastewater filtration. The first reverse osmosis membrane 5 and the second reverse osmosis membrane 6 are the main components of the filtration device. The fixing component 7 is used to fix the first reverse osmosis membrane 5 and the second reverse osmosis membrane 6. The threaded rail 1 8 and the threaded rail 2 9 are used to fix the two ends of the fixing component 7.

[0020] Reference Figure 2 and Figure 3The connecting pipe 10 is externally fixedly connected to a limiting block 11, a sealing ring 12, a limiting block 13, a sealing ring 14, and an outer fixing ring 15. The outer fixing ring 15 is internally threaded to the outside of the threaded rail 8. The connecting pipe 10 is externally slidably connected to an outer fixing ring 16, and the outer fixing ring 16 is internally threaded to the inside of the threaded rail 9.

[0021] Specifically, when it is necessary to install the fixing component 7, the rotating connecting pipe 10 is fixed at both ends of the reverse osmosis membrane 5 and the reverse osmosis membrane 6, the sealing ring 12 and the sealing ring 14 seal the interface after connection, and then the outer fixing ring 15 and the outer fixing ring 16 are rotated to fix the reverse osmosis membrane 5 and the reverse osmosis membrane 6 from the outside, so as to achieve the purpose of quick installation of the connection device.

[0022] Reference Figure 4 The filter outer tube 1 has a fixed groove 17 inside, and a screw 18 is threaded inside the fixed groove 17. One end of the screw 18 is rotatably connected to a compression block 19. A sealing ring 21 is slidably connected to the outside of the compression block 19. The sealing ring 21 is externally connected to one end of the reverse osmosis membrane 6. One end of the sealing ring 21 is slidably connected to a compression block 20.

[0023] Specifically, when it is necessary to fix the reverse osmosis membrane inside the filter outer tube 1, the first extrusion block 19 and the second extrusion block 20 are rotated, causing the screw 18 to rotate inside the fixing groove 17. Finally, the sealing ring 21 is squeezed outside the filter outer tube 1 and the second reverse osmosis membrane 6. The first extrusion block 19 restricts the outside of the filter outer tube 1 and the second reverse osmosis membrane 6, thereby achieving the purpose of fixing the reverse osmosis membrane.

The sealing ring 12 and the sealing ring 24 seal the interface after connection. Then, the outer fixing ring 15 and the outer fixing ring 26 are rotated to fix the reverse osmosis membrane 5 and the reverse osmosis membrane 6 from the outside, so as to achieve the purpose of quick installation of the connection device.

[0025] When it is necessary to fix the reverse osmosis membrane inside the filter outer tube 1, rotate the extrusion block 19 and the extrusion block 20 to drive the screw 18 to rotate inside the fixing groove 17. Finally, the sealing ring 3 21 is squeezed outside the filter outer tube 1 and the reverse osmosis membrane 2 6. The extrusion block 19 restricts the outside of the filter outer tube 1 and the reverse osmosis membrane 2 6, thereby achieving the purpose of fixing the reverse osmosis membrane.
