Abstract
Description
Technical Field
[0001] This application relates to the field of osmosis separation device technology, and in particular to a quick-install reverse osmosis membrane housing and reverse osmosis membrane module. Background Technology
[0002] With the development of water treatment technology, reverse osmosis membrane technology has emerged. Reverse osmosis membranes prevent certain substances from passing through the water, thus separating them from the water. When in use, reverse osmosis membrane housings need to be installed externally to control and guide the water flow.
[0003] A reverse osmosis membrane housing typically consists of a shell open at both ends and a cover fitted over the openings. In related technologies, the cover and shell are usually connected and secured using side spring clips at the connection point. This method requires specific tools for disassembly, making the process complex and time-consuming. Another method uses flanges, but flanges are larger and more expensive, increasing installation space and costs.
[0004] In addition, during the process of the cover closing the opening, the above connection method requires the operator to adjust the position of the cover and place it at the end of the shell to prevent misalignment. The precision of manual operation is low, which can easily lead to misalignment between the cover and the shell during the closing process. At this time, it is difficult to install connecting devices such as snap rings at the connection between the shell and the cover. Utility Model Content
[0005] Therefore, it is necessary to provide a quick-install reverse osmosis membrane housing and reverse osmosis membrane module to address the aforementioned problems of complex operation, high cost, and difficulty in calibrating the installation position.
[0006] On one hand, this application provides a quick-installation reverse osmosis membrane housing, including a cylindrical body. A cover is disposed at the end of the cylindrical body. A pad is sandwiched between the cover and the cylindrical body; the pad has protrusions on two sides, and grooves are formed on the surfaces of the cover and the cylindrical body facing the pad, the protrusions and grooves cooperating to detachably connect the cover and the cylindrical body to opposite sides of the pad. A clamp is disposed at the end of the cylindrical body, and the clamp is sleeved on the outer periphery of the cylindrical body and the cover; the inner wall of the clamp has a limiting groove, the inner sidewall of the limiting groove abutting against the outer surface of the cylindrical body and the outer surface of the cover, respectively, to limit the cover along the axial direction of the cylindrical body.
[0007] In some embodiments, the cylinder includes a cylinder body and a first snap-fit plate circumferentially disposed on the outer wall of the cylinder body, with the first snap-fit plate provided at both ends of the cylinder body; the side of the first snap-fit plate away from the cover abuts against the inner wall of the limiting groove. The cover includes a cover plate and a second snap-fit plate circumferentially disposed on the edge of the cover plate; the second snap-fit plate is connected to the first snap-fit plate through the pad; the side of the second snap-fit plate away from the cylinder abuts against the inner wall of the limiting groove.
[0008] In some embodiments, the outer wall of the first snap-fit plate is parallel to the outer wall of the cylinder body, and the side of the first snap-fit plate that contacts the inner wall of the limiting groove is inclined relative to the outer wall of the first snap-fit plate, so that the cross-sectional shape of the first snap-fit plate is trapezoidal, and the thickness of the end of the first snap-fit plate away from the cylinder body is less than the thickness of the end near the cylinder body; the outer wall of the second snap-fit plate is parallel to the outer wall of the cover plate, and the side of the second snap-fit plate that contacts the inner wall of the limiting groove is inclined relative to the outer wall of the second snap-fit plate, so that the cross-sectional shape of the second snap-fit plate is trapezoidal, and the thickness of the end of the second snap-fit plate away from the cover plate is less than the thickness of the end near the cover plate.
[0009] In some embodiments, the cover further includes a positioning ring and an extension rod. The positioning ring is disposed inside the cylindrical body and connected to the cover plate via the extension rod. The outer wall of the positioning ring abuts against the inner wall of the cylindrical body.
[0010] In some embodiments, the cover plate has a water outlet on its surface.
[0011] In some embodiments, the clamp includes a snap-fit mechanism and two snap rings, the snap rings being semi-circular, with one end of each snap ring hinged together; the other end of each snap ring is connected by the snap-fit mechanism.
[0012] In some embodiments, each of the two retaining rings has a retaining groove at one end that is far from each other. The retaining mechanism includes a retaining rod, one end of which is hinged to the retaining groove of one of the retaining rings, and the other end of which is engaged in the retaining groove of the other retaining ring.
[0013] In some embodiments, the pad is made of polytetrafluoroethylene.
[0014] In some embodiments, the side of the cylinder is provided with through holes, and there are multiple through holes. The multiple through holes are respectively provided at both ends of the cylinder, and the through holes located at the same end of the cylinder are arranged opposite each other.
[0015] On the other hand, this application provides a reverse osmosis membrane assembly, including a reverse osmosis membrane and a quick-install reverse osmosis membrane housing as described above, wherein the reverse osmosis membrane is disposed within the housing.
[0016] The aforementioned quick-install reverse osmosis membrane housing and module have two covers respectively placed on both ends of the housing to seal the openings at both ends. A gasket is sandwiched between the housing and the cover; the gasket material is relatively soft, improving the seal between the housing and the cover. The protrusions on the side of the gasket correspond to grooves on the surfaces of the housing and the cover, providing positioning during cover installation to ensure proper alignment and further improve sealing. Clamps abut against the outer surfaces of the housing and the cover, providing a limit and preventing displacement of the cover away from the housing, ensuring stable installation. By replacing the retaining spring with clamps, the clamps can be quickly removed and installed while ensuring the stability of the quick-install reverse osmosis membrane housing and module, thus simplifying cover installation. Furthermore, the clamps are designed to fit the dimensions of the housing and the cover, are small in size, and are made of readily available materials, resulting in low cost.

[0029] See Figure 1 , Figure 1This diagram illustrates the external structure of a quick-install reverse osmosis membrane housing according to an embodiment of this application. The quick-install reverse osmosis membrane housing provided in this embodiment includes a cylindrical body 100, a cover 200, a gasket 300, and a clamp 400. Understandably, the cylindrical body 100 is a cylindrical structure that encloses a receiving space to house the reverse osmosis membrane. Specifically, the cover 200 is placed over the end of the cylindrical body 100 to seal the end of the cylindrical body 100, thereby collectively enclosing a space for installing the reverse osmosis membrane. The gasket 300 is sandwiched between the cover 200 and the cylindrical body 100; each of the two sides of the gasket 300 has a protrusion 310, and both the cover 200 and the cylindrical body 100 have grooves on their surfaces facing the gasket 300. The protrusions 310 and the grooves cooperate, allowing the cover 200 and the cylindrical body 100 to be detachably connected to opposite sides of the gasket 300. A clamp 400 is provided at the end of the cylinder 100 and is sleeved on the outer periphery of the cylinder 100 and the cover 200. A limiting groove 410 is provided on the inner wall of the clamp 400. The inner side wall of the limiting groove 410 abuts against the outer surface of the cylinder 100 and the outer surface of the cover 200 respectively, so as to limit the cover 200 along the axial direction of the cylinder 100 to the cylinder 100.
[0030] It should be noted that the reverse osmosis membrane (not shown in the figure) is installed inside the cylinder 100 through the openings at both ends of the cylinder 100, with the outer wall of the reverse osmosis membrane fitting against the inner wall of the cylinder 100. Two gaskets 300 are provided, placed at the openings at both ends of the cylinder 100. Similarly, two covers 200 are provided, covering the gaskets 300 at both ends of the cylinder 100, clamping the gaskets 300 between the cylinder 100 and the covers 200. The gaskets 300 are made of a relatively soft material; the covers 200 and the cylinder 100 apply pressure to the gaskets 300, causing them to deform, resulting in a tight fit between the cylinder 100 and the gaskets 300, and between the covers 200 and the gaskets 300, increasing the seal. Clamps 400 are located on the outer periphery of the cylinder 100 and the covers 200 for easy installation; the clamps 400 can be installed and removed manually without the need for specific tools. The outer surfaces of the cylinder 100 and the cover 200 may be provided with protrusions or grooves, so that the inner sidewall of the limiting groove 410 abuts against the outer surface of the cylinder 100 and the outer surface of the cover 200 respectively, providing a limit for the cover 200 and preventing the cover 200 from detaching from the cylinder 100.
[0031] See Figure 1 and Figure 2During installation of this quick-install reverse osmosis membrane housing, the reverse osmosis membrane is inserted into the housing 100. The gaskets 300 are placed at both ends of the housing 100. The operator, based on the slot positions on the housing 100, aligns the protrusions 310 of the gaskets 300 facing the housing 100 into the slots. Then, based on the position of the protrusions 310 on the side of the gaskets 300 away from the housing 100, the cover 200 is placed over both ends of the housing 100, ensuring that the protrusions 310 on the side of the gaskets 300 away from the housing 100 are aligned with the slots on the surface of the cover 200, guaranteeing a tight fit between the cover 200 and the gaskets 300, and a tight fit between the gaskets 300 and the housing 100. The clamps 400 are then fitted onto the connection between the cover 200 and the housing 100 to limit the movement of the cover 200, completing the installation.
[0032] With the above-mentioned design, the clamp 400 can be quickly installed and removed, improving the overall assembly and disassembly efficiency of this quick-install reverse osmosis membrane housing. The sealing performance is improved by placing a gasket 300 between the cover 200 and the cylinder 100; the installation accuracy of the cover 200 is improved by the cooperation of the protrusion 310 and the slot, preventing misalignment between the cover 200 and the cylinder 100.
[0033] See Figure 3 In some embodiments, the cylinder 100 includes a cylinder body 110 and a first snap-fit plate 120 circumferentially disposed on the outer wall of the cylinder body 110. The first snap-fit plate 120 is provided at both ends of the cylinder body 110. The side of the first snap-fit plate 120 away from the cover 200 abuts against the inner wall of the limiting groove 410. The cover 200 includes a cover plate 210 and a second snap-fit plate 220 circumferentially disposed on the edge of the cover plate 210. The second snap-fit plate 220 is connected to the first snap-fit plate 120 via a pad 300. The side of the second snap-fit plate 220 away from the cylinder 100 abuts against the inner wall of the limiting groove 410.
[0034] It should be noted that there are two first snap-fit plates 120, which are respectively located at the two ends of the cylindrical body 110 to facilitate connection with the cover 200. The first snap-fit plates 120 are arranged radially along the cylindrical body 100. When the cover 200 is placed on the end of the cylindrical body 100, the first snap-fit plate 120 and the second snap-fit plate 220 are connected on opposite sides by a pad 300. The sealing of the connection between the first snap-fit plate 120 and the second snap-fit plate 220 is improved by squeezing the pad 300. The opposing sides of the first snap-fit plate 120 and the second snap-fit plate 220 abut against the inner wall of the limiting groove 410. The width of the limiting groove 410 is slightly less than the sum of the thicknesses of the first snap-fit plate 120, the second snap-fit plate 220, and the pad 300, so that when the clamp 400 abuts, it can squeeze the first snap-fit plate 120 and the second snap-fit plate 220, thereby squeezing the pad 300, ensuring a seal while fixing the cover 200 and the cylinder 100. By setting the first snap-fit plate 120 and the second snap-fit plate 220, the clamp 400 can be installed on the outer periphery of the cylinder 100 and the cover 200, allowing operators to directly install and remove the clamp 400, effectively improving operational efficiency.
[0035] See Figure 3 In some embodiments, the outer wall of the first snap-fit plate 120 is parallel to the outer wall of the cylinder body 110, and the side of the first snap-fit plate 120 that contacts the inner wall of the limiting groove 410 is inclined relative to the outer wall of the first snap-fit plate 120, so that the cross-sectional shape of the first snap-fit plate 120 is trapezoidal, and the thickness of the end of the first snap-fit plate 120 away from the cylinder body 110 is less than the thickness of the end near the cylinder body 110; the outer wall of the second snap-fit plate 220 is parallel to the outer wall of the cover plate 210, and the side of the second snap-fit plate 220 that contacts the inner wall of the limiting groove 410 is inclined relative to the outer wall of the second snap-fit plate 220, so that the cross-sectional shape of the second snap-fit plate 220 is trapezoidal, and the thickness of the end of the second snap-fit plate 220 away from the cover plate 210 is less than the thickness of the end near the cover plate 210.
[0036] The cross-sectional shape of both the first snap-fit plate 120 and the second snap-fit plate 220 is a right-angled trapezoid. It should be noted that... (See also...) Figure 3During installation, the facing sides of the first snap-fit plate 120 and the second snap-fit plate 220 are vertical planes, while the opposing sides are inclined surfaces. Correspondingly, the cross-sectional shape of the limiting groove 410 is an isosceles trapezoid. When the clamp 400 is fitted onto the connection between the cylinder 100 and the cover 200, the inner wall of the limiting groove 410 provides pressure to the first snap-fit plate 120 pointing towards the central axis of the cylinder 100. Simultaneously, the inner wall of the limiting groove 410 provides pressure to the second snap-fit plate 220 pointing towards the center of the cover 210, ensuring that the cover 200 and the cylinder 100 remain coaxial and are less prone to misalignment. Furthermore, the inclined surfaces abut against each other, increasing the contact area between the inner wall of the limiting groove 410 and the first and second snap-fit plates 120 and 220, resulting in more even force distribution on the contact surfaces, reducing the risk of damage over long-term use, and extending service life.
[0037] See Figure 4 In some embodiments, the cover 200 further includes a positioning ring 230 and an extension rod 240. The positioning ring 230 is disposed inside the cylindrical body 110 and is connected to the cover plate 210 through the extension rod 240. The outer wall of the positioning ring 230 abuts against the inner wall of the cylindrical body 110.
[0038] It should be noted that the positioning ring 230 is set parallel to the cover plate 210, and the positioning ring 230 is fixedly connected to the cover plate 210. When installing the cover 200, first place the positioning ring 230 into the cylinder body 110. Since the outer wall of the positioning ring 230 abuts against the inner wall of the cylinder body 110, the cover plate 210 cannot move radially relative to the cylinder body 110. Simply move the cover 200 closer to the cylinder body 110 to accurately cover the end of the cylinder body 110, ensuring that the cover 200 is not misaligned with the cylinder body 100 during installation, which facilitates quick installation of the cover 200 by the operator.
[0039] In addition, the positioning ring 230 can abut against the end of the reverse osmosis membrane. The positioning rings 230 at both ends of the cylinder body 110 abut against the two ends of the reverse osmosis membrane respectively, providing a limit for the reverse osmosis membrane and preventing the reverse osmosis membrane from sliding along the axial direction of the cylinder body 110 inside the cylinder body 110 during use.
[0040] See Figure 4 In some embodiments, the surface of the cover plate 210 is provided with a water outlet 211.
[0041] It should be noted that the outlet 211 is located on the bottom surface of the cover plate 210 at one end of the cylinder 100 and extends through the cover plate 210. The outlet 211 is connected to the pure water outlet in the middle of the reverse osmosis membrane. The liquid treated by the reverse osmosis membrane is discharged to the designated location through the outlet 211 for easy use or subsequent processing.
[0042] See Figure 5 In some embodiments, the clamp 400 includes a snap-fit mechanism 420 and two snap rings 430, the snap rings 430 being semi-circular, with one end of each snap ring 430 hinged together; the other ends of the two snap rings 430 are connected through the snap-fit mechanism 420.
[0043] It should be noted that the two retaining rings 430 can rotate around the hinge. During clamping, the retaining rings 430 are wrapped around both ends of the cylinder 100. Rotating the retaining rings 430 brings their other ends into contact, forming a ring that fits around the outer circumference of the connection between the cylinder 100 and the cover 200. The two retaining rings 430 are then connected and fixed via the locking mechanism 420 to secure the cylinder 100 and the cover 200. This structure with two retaining rings 430 allows for quick and easy disassembly and installation, improving efficiency.
[0044] In some embodiments, each of the two retaining rings 430 has a retaining groove 431 at one end that is far apart from each other. The retaining mechanism 420 includes a retaining rod 421, one end of which is hinged to the retaining groove 431 of one of the retaining rings 430, and the other end of which is engaged in the retaining groove 431 of the other retaining ring 430.
[0045] See Figure 5 It should be noted that the snap-fit groove 431 is located at the edge of the other end of the two snap rings 430, facilitating its engagement with the snap-fit rod 421. The snap-fit mechanism 420 also includes a snap-fit connector 422 located at the other end of the snap-fit rod 421, the diameter of which is larger than the width of the snap-fit groove 431. Figure 5 As shown, when the non-hinged end of the locking rod 421 rotates into the locking groove 431, the bottom of the locking connector 422 abuts against the side wall of the locking groove 431, providing a limit for the retaining ring 430 and keeping the other ends of the two retaining rings 430 connected. When the non-hinged end of the locking rod 421 rotates out of the locking groove 431, the locking connector 422 does not provide a limit, and the retaining ring 430 can rotate and separate. With the above settings, the operator can directly operate the locking rod 421 to install and remove the clamp 400 without additional tools, and the operation is simple and quick, effectively improving operational efficiency.
[0046] Furthermore, the width of the snap-fit groove 431 can be set slightly smaller than the width of the other end of the snap-fit rod 421. The sidewall of the snap-fit groove 431 is prone to deformation. When the snap-fit rod 421 rotates to the opening of the snap-fit groove 431, applying force within the snap-fit groove 431 to the snap-fit rod 421 will compress the sidewall at the opening of the snap-fit groove 431, increasing its width. When the snap-fit rod 421 snaps into the snap-fit groove 431, the width at the opening of the snap-fit groove 431 returns to its initial state, securing the snap-fit rod 421 inside the snap-fit groove 431. The inner sidewall of the snap-fit groove 431 contacts the side of the snap-fit rod 421, providing frictional restraint to achieve a stable snap-fit. This setup also achieves the snap-fit effect, and disassembly and assembly can be performed without additional tools, making the operation simple and quick.
[0047] In some embodiments, the material of the pad 300 is polytetrafluoroethylene.
[0048] It should be noted that polytetrafluoroethylene (PTFE) is a relatively soft material and insoluble in water, which makes it easy to fit with the cylinder 100 and the cover 200, improving the sealing between the cylinder 100 and the cover 200. In addition, the material is relatively common and easy to process, which can reduce the manufacturing cost.
[0049] In some embodiments, the side of the cylinder 100 is provided with a through hole 130.
[0050] It should be noted that multiple reverse osmosis membranes are typically used, and these membranes are connected sequentially, allowing the water to be treated to pass through multiple membranes for processing, thus improving the treatment efficiency. For this purpose, through-holes 130 are provided on the side of the cylinder 100 for water inlet or for connection with through-holes 130 of other quick-connect reverse osmosis membrane housings. These through-holes connect multiple quick-connect reverse osmosis membrane housings, guiding the water flow through the corresponding number of reverse osmosis membranes for treatment.
[0051] In some embodiments, multiple through holes 130 are provided, with the multiple through holes 130 respectively located at both ends of the cylinder 100, and the through holes 130 located at the same end of the cylinder 100 are arranged opposite each other in pairs. This allows one quick-install reverse osmosis membrane housing to communicate with multiple adjacent quick-install reverse osmosis membrane housings, facilitating water flow guidance and improving water treatment efficiency.
[0052] In addition, during the liquid processing process, the reverse osmosis membrane accumulates separated fouling or ions. Part of the liquid is used to clean these fouling and ions, forming concentrate, which is discharged from the concentrate outlet of the reverse osmosis membrane. Some through-holes 130 can be connected to the concentrate outlet of the reverse osmosis membrane to discharge the concentrate produced after reverse osmosis filtration.
[0053] A reverse osmosis membrane assembly includes a reverse osmosis membrane and a quick-install reverse osmosis membrane housing as described above, wherein the reverse osmosis membrane is disposed within a cylindrical body 100.
[0054] In some embodiments, the reverse osmosis membrane has a cylindrical structure and is installed in the quick-install reverse osmosis membrane housing to form a reverse osmosis assembly. The water to be treated entering the quick-install reverse osmosis membrane housing can contact the reverse osmosis membrane to treat the water.
[0055] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0056] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
