Description

Technical Field

[0001] This utility model relates to the field of water treatment membrane housing technology, and specifically to a water treatment membrane housing that is easy to assemble. Background Technology

[0002] Water treatment membrane housings are pressure-resistant containers used in water treatment systems to house and protect spiral wound membrane elements such as reverse osmosis membranes and nanofiltration membranes. They are core supporting equipment for membrane separation technology. Their main functions are to fix the membrane elements, withstand the high-pressure water flow during the membrane separation process, and guide the raw water, concentrate, and product water to flow along specific paths to ensure the efficient and stable operation of the membrane elements. The main components of the membrane housing include the housing, end caps, and sealing rings. In use, the membrane element is placed into the housing, then the membrane element is connected to the adapter, and then the sealing rings and end caps are put on. The specific operating steps for closing the end cap are as follows: The first step is to cover the end cap with the end of the housing, aligning the screw holes of the end cap and the housing. The second step is to use screws threaded through the end cap and the housing to secure the end cap and the housing. In summary, existing water treatment membrane housings have some defects, such as: When performing the second step of the above-mentioned middle cover and upper end cover, there are a large number of screws, usually no less than six, which means that workers need to tighten multiple screws one by one, which is labor-intensive and inconvenient for assembly.

[0003] Therefore, this utility model provides a water treatment membrane housing that is easy to assemble, in order to solve the above problems. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a water treatment membrane housing that is easy to assemble, so as to solve the problem mentioned above that the workers need to screw on multiple screws in sequence, which makes the assembly inconvenient.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A water treatment membrane housing that is easy to assemble includes a housing, a mounting plate, a sealing plate, and a wedge plate; Mounting plate: The mounting plate is integrally molded at the end of the housing; Sealing disc: The sealing disc covers the side of the mounting disc away from the housing, and the sealing disc is fixedly snapped onto the mounting disc along the axial direction of the mounting disc by the first snap-fit ​​assembly; Wedge plate: The wedge plate covers the side of the sealing plate away from the mounting plate. The wedge plate is fixedly snapped between the mounting plate and the sealing plate along the radial direction of the mounting plate by a second snap-fit ​​assembly. Through the above technical solution, the first snap-fit ​​assembly fixes the sealing disc axially to the mounting disc, and the second snap-fit ​​assembly fixes the sealing disc radially to the mounting disc, thereby fixing the sealing disc to the mounting disc in all directions. Furthermore, the sealing disc bears the axial water pressure, while the wedge disc does not bear the axial water pressure, thus ensuring that the wedge disc will not detach from the mounting disc and the sealing disc at will, thereby ensuring the installation stability of the mounting disc and the sealing disc and ensuring the safety of use.

[0006] Preferably, the first snap-fit ​​assembly includes a groove, a T-shaped wedge, and an extension groove. The groove is disposed on the side of the mounting plate near the sealing plate, and the groove extends radially from the mounting plate to form the extension groove. The first end of the T-shaped wedge is fixedly connected to the sealing plate, and the second end of the T-shaped wedge rotates from the groove radially into the extension groove. With the above technical solution, when the T-shaped wedge is inserted into the extension groove, the side wall of the extension groove blocks the T-shaped wedge, and the T-shaped wedge will not come out along the axial direction of the mounting plate, thereby fixing the sealing plate axially on the mounting plate.

[0007] Preferably, an arc-shaped guide rail is fixedly connected to the inner side of the extension groove, a top block is movably inserted between the extension groove and the groove, the arc-shaped guide rail moves radially through the top block along the mounting plate, the top block abuts against the second end of the T-shaped wedge, a spring is fixed between the top block and the inner side of the extension groove, and the arc-shaped guide rail is located inside the spring. With the above technical solution, the spring pushes the top block, and the top block pushes the T-shaped wedge. After the restriction of the second snap-fit ​​component is removed, the T-shaped wedge and the sealing disc can be actively pushed to rotate along the radial direction of the mounting disc, thereby actively returning to their original position, making it more convenient to operate the sealing disc.

[0008] Preferably, the second snap-fit ​​assembly includes a pin and a socket. Sockets are provided in the sealing disc, the third end of the T-shaped wedge, and the side wall of the groove. The pin is fixedly connected to the side of the wedge disc and can be movably inserted into the socket in the sealing disc, the socket at the third end of the T-shaped wedge, and the socket in the side wall of the groove. The above technical solution uses a pin that passes through the insertion hole in the sealing disc, the insertion hole at the third end of the T-shaped wedge, and the insertion hole in the side wall of the groove to restrict the sealing disc from rotating radially along the mounting disc, thereby fixing the sealing disc radially onto the mounting disc.

[0009] Preferably, the vertical cross-section of the section of the pin located inside the socket is elliptical; Through the above technical solution, the moment the pin is inserted into the socket in the sealing disc, the socket at the third end of the T-shaped wedge, and the socket in the side wall of the groove, the sealing disc can be quickly rotated in the opposite direction by a small angle to lock into the elliptical section of the pin, thus preventing the pin from slowly coming out of the socket when subjected to slight vibration.

[0010] Preferably, a sealing ring is fixedly clamped between the inner circumference of the mounting plate and the sealing plate; The above technical solution increases the sealing performance of the mounting plate and the sealing plate.

[0011] Preferably, a rotating ring is rotatably inserted into the side of the sealing disc, and the sealing ring is sandwiched between the rotating ring and the mounting disc; With the above technical solution, since the sealing disc needs to rotate, the sealing ring will be twisted when the sealing disc rotates. Therefore, a rotating ring is set so that the sealing ring will not be twisted when the sealing disc rotates. In other words, the sealing ring is protected by the rotating ring.

[0012] The beneficial effects of this utility model are as follows: In summary, this device can fix the sealing disc to the mounting disc from both axial and radial directions. Furthermore, the sealing disc bears the axial water pressure, while the wedge disc does not, thus ensuring that the wedge disc will not detach from the mounting disc and the sealing disc at will. This guarantees the installation stability of the mounting disc and the sealing disc, ensuring safety in use. The first and second snap-fit ​​components replace screws to fix the mounting disc and the sealing disc. Multiple first and second snap-fit ​​components can be snapped in one go, eliminating the need to snap them in one by one, making assembly more convenient and faster, and reducing the labor intensity of workers.

The wedge plate 4 covers the side of the sealing plate 3 away from the mounting plate 2. A handle 5 is fixedly connected to the outer side of the wedge plate 4. The wedge plate 4 can be picked up or rotated using the handle 5. The wedge plate 4 is fixedly snapped between the mounting plate 2 and the sealing plate 3 along the radial direction of the mounting plate 2 by the second snap-fit ​​assembly. A rotating ring 15 is inserted into the inner side of the sealing plate 3. The sealing ring 14 is sandwiched between the rotating ring 15 and the mounting plate 2.

[0026] In this embodiment, refer to the appendix. Figure 2 Appendix Figure 4 Appendix Figure 7 and attached Figure 8The first snap-fit ​​assembly includes a groove 7, a T-shaped wedge 9, and an extension groove 11. The groove 7 is located on the side of the mounting plate 2 near the sealing plate 3. There are no fewer than three grooves 7. The grooves 7 are arranged in a circular array around the center of the mounting plate 2 on the side of the mounting plate 2. The grooves 7 extend into the extension groove 11 radially along the mounting plate 2. The first end of the T-shaped wedge 9 is fixedly connected to the sealing plate 3. The second end of the T-shaped wedge 9 rotates from the groove 7 radially along the mounting plate 2 and is inserted into the extension groove 11. An arc-shaped guide rail 16 is fixedly connected to the inner side of the extension groove 11. A top block 12 is movably inserted between the extension groove 11 and the groove 7. The arc-shaped guide rail 16 moves radially through the top block 12 along the mounting plate 2. The top block 12 abuts against the second end of the T-shaped wedge 9. The corners of the top block 12 and the T-shaped wedge 9 are rounded. A spring 10 is fixed between the top block 12 and the inner side of the extension groove 11. The arc-shaped guide rail 16 is located inside the spring 10.

[0027] In this embodiment, refer to the appendix. Figure 2 Appendix Figure 4 Appendix Figure 7 and attached Figure 8 The second snap-fit ​​assembly includes a pin 8 and a socket 13. Sockets 13 are provided inside the sealing disc 3, at the third end of the T-shaped wedge 9, and on the side wall of the groove 7. The pin 8 is fixedly connected to the side of the wedge disc 4. The pin 8 is movably inserted into the socket 13 inside the sealing disc 3, the socket 13 at the third end of the T-shaped wedge 9, and the socket 13 on the side wall of the groove 7. (See attached diagram for reference.) Figure 9 The vertical cross-section of the pin 8 located inside the socket 13 is elliptical, and the edge of the socket 13 can be inserted into the elliptical section.

[0028] The working principle of this device is as follows: In use, place the membrane element into the housing 1, then first cover the sealing plate 3, inserting the T-shaped wedge 9 into the groove 7. Next, cover the wedge plate 4, inserting the pin 8 into the insertion holes 13 of the sealing plate 3 and the T-shaped wedge 9. While pressing the wedge plate 4, rotate it. The wedge plate 4, through the pin 8, drives the sealing plate 3 to rotate, causing the T-shaped wedge 9 to insert into the extension groove 11. The top block 12 moves, compressing the spring 10. Simultaneously, the pin 8 inserts into the insertion hole 13 of the mounting plate 2, completing the installation. Release the wedge plate 4; the spring 10 pushes the top block 12, which in turn pushes the T-shaped wedge 9, causing the entire sealing plate 3 to rotate back a small angle. At this point, the insertion holes 13 of the mounting plate 2 and the T-shaped wedge 9 are misaligned, locking into the elliptical section of the pin 8, achieving attachment. Figure 10 At the position shown, the pin 8 is stuck in the misaligned socket 13.
