Description

Technical Field

[0001] This utility model relates to the field of seawater desalination reverse osmosis membrane technology, specifically a high-flux seawater desalination reverse osmosis membrane module. Background Technology

[0002] High-flux reverse osmosis (RO) membrane modules are core components of current seawater desalination technology, and their performance directly affects water production efficiency, energy consumption, and cost. Spiral winding increases membrane area and optimizes the flow channel grid to improve flux, and multi-stage series connection allows for phased treatment of high-salinity water, achieving high-flux performance. However, RO membrane modules are typically connected by threads, requiring a torque wrench for disassembly, a time-consuming and labor-intensive process that hinders replacement and maintenance, presenting certain drawbacks. Therefore, we propose a high-flux reverse osmosis membrane module for seawater desalination. Utility Model Content

[0003] The present invention aims to solve the problems existing in the prior art or related technologies.

[0004] Therefore, the technical solution adopted by this utility model is as follows: a high-flux seawater desalination reverse osmosis membrane module, including a shell, a membrane, a water guide pipe, a lower support, a lower end cap, a pop-out structure, an upper support, and a fixing structure. The membrane is inserted inside the shell, the water guide pipe is fixedly connected to the membrane, the lower support abuts against the bottom of the membrane and the water guide pipe, the lower end cap is threaded to the bottom of the shell, the pop-out structure is fixedly disposed inside the lower end cap, the upper support abuts against the top of the membrane and the water guide pipe, and an annular groove is provided on the outer side of the upper support. The fixing structure includes a fixing stud threaded to the shell, a second spring fixedly disposed to the left of the fixing stud, and a turntable fixedly disposed to the left of the second spring.

[0005] Preferably, a stop and a mounting base are fixedly provided on the outer side of the housing, and an external thread is provided on the bottom of the housing.

[0006] Preferably, a water inlet pipe is provided at the bottom of the lower end cover, and a groove is provided on the inner side of the lower end cover.

[0007] Preferably, the pop-out structure includes a plurality of first springs fixedly disposed in the groove, a fixing ring fixedly disposed on the top of the plurality of first springs, and a rubber ring bonded to the top of the fixing ring.

[0008] Preferably, both the retaining ring and the rubber ring are inserted into the groove.

[0009] Preferably, the turntable has a rotating hole on its inner side, and the turntable is rotatably connected to the mounting base through the rotating hole.

[0010] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows: the fixing stud of the fixing structure can be rotated outward until the fixing stud is completely disengaged from the annular groove of the upper support. At this time, the upper support is unrestrained, and the first spring of the pop-out structure has a certain elastic potential energy, which allows the fixing ring and rubber ring to push the diaphragm, water guide pipe and upper support to move, so as to quickly pull the diaphragm, water guide pipe and upper support from the shell, achieving the effect of quick disassembly. Then, by rotating the fixing stud inward, it can be directly inserted into the annular groove of the upper support, thereby quickly fixing the diaphragm and water guide pipe. After fixing, the pop-out structure can hold the diaphragm and water guide pipe, which greatly improves the stability. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0026] The following description, in conjunction with the accompanying drawings, describes some embodiments of this utility model that provide a high-flux seawater desalination reverse osmosis membrane module.

[0027] Example 1:

[0028] Reference Figure 1-5 This is the first embodiment of the present invention, which provides a high-flux seawater desalination reverse osmosis membrane module, including a shell 100, a membrane 200, a water guide pipe 300, a lower support 400, a lower end cap 500, an upper support 700, and a fixing structure 800.

[0029] Specifically, a stop 101 and a mounting base 102 are fixedly provided on the outer side of the housing 100, and an external thread is provided on the bottom of the housing 100. In use, the stop 101 can block the lower end cover 500 so that the lower end cover 500 can be installed, while the mounting base 102 can be used to install the fixing structure 800 so that the upper support member 700 can be fixed.

[0030] Specifically, the membrane 200 is inserted inside the outer shell 100. In use, the membrane 200 is composed of multiple layers of membrane, which facilitates the desalination of seawater.

[0031] Specifically, the water pipe 300 is fixedly connected to the diaphragm 200. During use, pure water can be collected and discharged through the water pipe 300 for use.

[0032] Specifically, the lower support 400 abuts against the bottom of the membrane 200 and the water pipe 300. In use, the lower support 400 provides support for the membrane 200 to desalinate seawater.

[0033] Specifically, the lower end cover 500 is threaded to the bottom of the outer casing 100. The bottom of the lower end cover 500 is provided with a water inlet pipe 501. A groove 502 is provided on the inner side of the lower end cover 500. During use, the lower end cover 500 achieves a sealing effect, while the water inlet pipe 501 can transport seawater to the membrane 200 for desalination. The groove 502 can be used to install the fixing structure 800.

[0034] Specifically, the upper support 700 abuts against the top of the diaphragm 200 and the water pipe 300. An annular groove 701 is provided on the outer side of the upper support 700. In use, the upper support 700 can support and block the diaphragm 200 and the water pipe 300, while the annular groove 701 facilitates the fixing structure 800 to fix the upper support 700.

[0035] Specifically, the fixing structure 800 includes a fixing stud 801 threaded onto the housing 100, a second spring 802 fixedly disposed on the left side of the fixing stud 801, and a turntable 803 fixedly disposed on the left side of the second spring 802. The turntable 803 has a rotating hole 8031 ​​on its inner side. The turntable 803 is rotatably connected to the mounting base 102 through the rotating hole 8031. In use, the fixing stud 801 can be inserted into the annular groove 701 by rotating it, so as to quickly fix the upper support member 700. The second spring 802 makes the fixing stud 801 less prone to loosening, thus preventing the upper support member 700 from detaching from the fixing structure 800 due to the loosening of the fixing stud 801.

[0036] Example 2:

[0037] Reference Figure 1 and Figure 3 This is the second embodiment of the present invention, which differs from the first embodiment in that it further includes a pop-out structure 600. The pop-out structure 600 includes a plurality of first springs 601 fixedly disposed in the groove 502, a fixing ring 602 fixedly disposed on the top of the plurality of first springs 601, and a rubber ring 603 bonded to the top of the fixing ring 602. The fixing ring 602 and the rubber ring 603 are both inserted in the groove 502. In use, the first springs 601 cause the rubber ring 603 to push the diaphragm 200 and the water guide pipe 300 to move for quick disassembly. At the same time, it can hold the diaphragm 200 and the water guide pipe 300 together to improve the stability of the device.

[0038] The working principle and usage process of this utility model are as follows: In use, the diaphragm 200 and the water guide tube 300 can be directly inserted into the outer shell 100. After insertion, rotate the lower end cover 500 to connect with the bottom thread of the outer shell 100. Then squeeze the diaphragm 200 and the water guide tube 300 until the groove 502 of the upper support 700 is aligned with the fixing structure 800. After alignment, rotate the fixing stud 801 to insert it into the groove 502 to fix the diaphragm 200 and the water guide tube 300. When disassembling, the fixing stud 801 can be rotated outward until the fixing stud 801 is completely disengaged from the groove 502. After disengagement, the pop-out structure 600 will push the fixed diaphragm 200 and the water guide tube 300. Then, the diaphragm 200 and the water guide tube 300 can be moved upward to disengage from the outer shell 100. Alternatively, the lower end cover 500 can be rotated downward with a wrench. After rotation and disengagement, the diaphragm 200 and the water guide tube 300 can be pulled out downward.

[0039] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
