AI Technical Summary
In existing technologies, reverse osmosis membranes are prone to slippage during disassembly due to unstable contact between the tool and the membrane, making them difficult to remove effectively.
A reverse osmosis membrane disassembly device was designed. By using limiting and movable parts to squeeze the elastic part, the size of the elastic part in the direction perpendicular to the axial direction of the rod is increased, thereby making it fit tightly with the reverse osmosis membrane, increasing the friction and preventing slippage.
By increasing the friction between the elastic element and the reverse osmosis membrane, slippage is prevented, ensuring stable disassembly of the reverse osmosis membrane.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of water treatment equipment maintenance technology, and in particular to a reverse osmosis membrane disassembly device. Background Technology
[0002] In modern water treatment processes, reverse osmosis technology plays a crucial role due to its high-precision filtration efficiency. Reverse osmosis membranes, as the core filtration element, are widely encapsulated in various membrane housings. Therefore, reverse osmosis membranes are used in everything from small household water purifiers to large-scale industrial pure water production systems. When a reverse osmosis membrane reaches its service life or needs replacement due to fouling and blockage, it generally needs to be removed from the narrow and relatively deep membrane housing.
[0003] In existing technologies, tools such as pry bars or homemade hooks are usually used to remove reverse osmosis membranes. However, when these tools come into contact with the reverse osmosis membrane, the force points are unstable, which can cause the tools to slip on the reverse osmosis membrane. Utility Model Content
[0004] This invention provides a reverse osmosis membrane disassembly device to prevent slippage when attaching to a reverse osmosis membrane.
[0005] This utility model provides a reverse osmosis membrane disassembly device, comprising:
[0006] rods;
[0007] A limiting member is provided at one end of the rod;
[0008] A movable component, sleeved on the rod, capable of switching between a first position and a second position along the axial direction of the rod, wherein the movable component in the second position is closer to the limiting member than the movable component in the first position; and
[0009] An elastic element is sleeved on the rod and located between the limiting element and the movable element;
[0010] When the movable member switches from the first position to the second position along the axial direction of the rod, the movable member and the limiting member squeeze the elastic member, causing the size of the elastic member in the direction perpendicular to the axial direction of the rod to increase from the initial value to the preset value, so that the elastic member fits with the reverse osmosis membrane.
[0011] In some embodiments, when the movable member is in the first position, the elastic member abuts against the limiting member and the movable member at both ends in the axial direction of the rod, respectively.
[0012] In some embodiments, at least a portion of the outer surface of the rod is provided with external threads, the movable member is provided with internal threads, and the movable member and the threaded area of the rod form a threaded connection. When the rod rotates, the movable member switches between the first position and the second position along the axial direction of the rod.
[0013] In some embodiments, a handle is also included, which is located at the end of the rod away from the limiting member.
[0014] In some embodiments, there are multiple elastic elements, which are arranged along the axial direction of the rod and are all located between the limiting member and the movable member.
[0015] In some embodiments, a separator is provided between two adjacent elastic elements.
[0016] In some implementations, it also includes:
[0017] Supporting part; and
[0018] A support portion is disposed on the bearing portion, and the support portion has a first end and a second end opposite to each other;
[0019] The rod is inserted through the support portion, and its two ends pass through the first end and the second end respectively. The movable member is located on the side of the first end away from the second end, and the rod is rotatable relative to the support portion.
[0020] In some embodiments, the support is movably disposed on the bearing portion, and the support is movable along the axial direction of the rod.
[0021] In some embodiments, the outer surface of the second end is configured as a rack, and the bearing portion is rotatably provided with a gear that meshes with the rack, the gear rotating to drive the support portion to move axially along the rod.
[0022] In some embodiments, the gear is provided with a handle.
[0023] This application provides a reverse osmosis membrane disassembly device, which, compared with the prior art, has at least the following features:
[0024] Beneficial effects:
[0025] Because the limiting component and the moving component squeeze the elastic component, the elastic component is forced to increase in size in the direction perpendicular to the axial direction of the rod. This causes the elastic component to fit into the reverse osmosis membrane, increasing the number of points of contact between the elastic component and the reverse osmosis membrane. This also increases the friction between the elastic component and the reverse osmosis membrane, preventing slippage between the elastic component and the reverse osmosis membrane.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0036] The technical solution of this application will be further described below with reference to specific embodiments and accompanying drawings.
[0037] Please see Figure 1 This application provides a reverse osmosis membrane disassembly device 1, including a rod 11, a limiting member 12, a movable member 13, and an elastic member 14. The limiting member 12 is disposed at one end of the rod 11. The movable member 13 is sleeved on the rod 11, and the movable member 13 can switch between a first position and a second position along the axial direction of the rod 11, wherein the movable member 13 is closer to the limiting member 12 in the second position than it is in the first position. The elastic member 14 is sleeved on the rod 11, and the elastic member 14 is located between the limiting member 12 and the movable member 13. When the movable member 13 switches from the first position to the second position along the axial direction of the rod 11, the movable member 13 and the limiting member 12 compress the elastic member 14, causing the dimension of the elastic member 14 in the direction perpendicular to the axial direction of the rod 11 to increase from an initial value to a preset value, so that the elastic member 14 fits against the reverse osmosis membrane.
[0038] In this embodiment, the reverse osmosis membrane disassembly device 1 is first aligned with the opening of the membrane housing, and then at least part of the rod 11 is extended into the membrane housing. At this time, the limiting member 12, the elastic member 14 and the movable member 13 can all be located inside the membrane housing.
[0039] It should be noted that at this time, the movable part 13 is in the first position, and the elastic part 14 is not squeezed. That is, the dimension of the elastic part 14 in the direction perpendicular to the axial direction of the rod 11 is the initial value, which is smaller than the inner diameter of the reverse osmosis membrane installed in the membrane shell. In other words, at this time, the elastic part 14 is not in contact with the reverse osmosis membrane.
[0040] The movable part 13 switches from the first position to the second position along the axial direction of the rod 11. At this time, the movable part 13 and the limiting part 12 squeeze the elastic part 14, forcing the elastic part 14 to increase in size in the direction perpendicular to the axial direction of the rod 11, from the initial value to the preset value. At this time, the elastic part 14 is tightly attached to the reverse osmosis membrane.
[0041] Then, the reverse osmosis membrane disassembly device 1 is pulled out from the opening of the membrane housing. At this time, because the elastic element 14 is tightly attached to the reverse osmosis membrane, the elastic element 14 moves and drives the reverse osmosis membrane to move. That is, when the elastic element 14 is pulled out from the opening of the membrane housing, it drives the reverse osmosis membrane.
[0042] It is understandable that because the limiting member 12 and the moving member 13 squeeze the elastic member 14, the elastic member 14 is forced to increase in size in the direction perpendicular to the axial direction of the rod member 11, so that the elastic member 14 fits into the reverse osmosis membrane, increasing the force points between the elastic member 14 and the reverse osmosis membrane, which also increases the friction between the elastic member 14 and the reverse osmosis membrane, thus preventing slippage between the elastic member 14 and the reverse osmosis membrane.
[0043] In some embodiments, when the movable member 13 is in the first position, the elastic member 14 abuts against the limiting member 12 and the movable member 13 at both ends of the rod 11 in the axial direction.
[0044] When the movable part 13 is in the first position, the elastic part 14 abuts against the limiting part 12 and the movable part 13 at both ends of the rod 11 in the axial direction, so that during the entire process of the movable part 13 switching from the first position to the second position, the limiting part 12 and the movable part 13 continuously squeeze the elastic part 14. In other words, there is no empty stroke of the movable part 13 during the process of switching from the first position to the second position, which improves the squeezing efficiency of the elastic part 14.
[0045] Please see Figure 2 In some embodiments, at least a portion of the outer surface of the rod 11 is provided with external threads, and the movable member 13 is provided with internal threads. The movable member 13 and the threaded area of the rod 11 form a threaded connection. When the rod 11 rotates, the movable member 13 switches between a first position and a second position along the axial direction of the rod 11.
[0046] In this embodiment, when it is necessary to compress the elastic member 14, the rotating rod 11 causes the movable member 13 to switch from the first position to the second position along the axial direction of the rod 11, forcing the elastic member 14 to increase in size in the direction perpendicular to the axial direction of the rod 11, from the initial value to the preset value.
[0047] Understandably, the rotating rod 11 can precisely control the distance the movable part 13 moves from the first position to the second position, thereby adapting to reverse osmosis membranes of different sizes.
[0048] For example, when the reverse osmosis membrane is inside the first membrane housing and the inner diameter of the first membrane housing is small, the rod 11 can rotate fewer times, so that the moving part 13 moves a smaller distance from the first position to the second position. At this time, the force applied to the elastic part 14 by the moving part 13 and the limiting part 12 when they squeeze the elastic part 14 is smaller, and the deformation of the elastic part 14 is smaller. As a result, the difference between the preset value and the initial value of the elastic part 14 after the size increases in the direction perpendicular to the axial direction of the rod 11 is smaller.
[0049] When the reverse osmosis membrane is inside the second membrane housing and the inner diameter of the second membrane housing is large, the rod 11 can rotate a large number of times, so that the movable part 13 moves a large distance from the first position to the second position. At this time, when the movable part 13 and the limiting part 12 squeeze the elastic part 14, the force applied to the elastic part 14 is large, and the deformation of the elastic part 14 is large. As a result, the difference between the preset value and the initial value of the increased size of the elastic part 14 in the direction perpendicular to the axial direction of the rod 11 is large.
[0050] Please refer to the following: Figure 1 and Figure 2 In some embodiments, the reverse osmosis membrane disassembly device 1 further includes a handle 15, which is disposed at the end of the rod 11 away from the limiting member 12.
[0051] By providing a handle 15 at the end of the rod 11 away from the limiting member 12, it is convenient for the operator to hold the handle 15 and rotate the rod 11. Of course, in some other embodiments, the rod 11 can also be driven by a driving device.
[0052] Please see Figure 3 In some embodiments, there are multiple elastic elements 14, which are arranged along the axial direction of the rod 11, and all of the multiple elastic elements 14 are located between the limiting member 12 and the movable member 13.
[0053] It is understandable that reverse osmosis membranes are generally quite long. To increase the contact points between the elastic element 14 and the reverse osmosis membrane, the axial length of the elastic element 14 in the rod 11 is generally matched with the length of the reverse osmosis membrane. However, when the axial length of the elastic element 14 in the rod 11 is long, when the limiting member 12 and the movable member 13 compress the elastic element 14, some areas of the elastic element 14 may not be in contact with the reverse osmosis membrane due to its length. To solve this problem, this embodiment uses multiple elastic elements 14 between the limiting member 12 and the movable member 13, thereby reducing the axial length of each elastic element 14 in the rod 11. This ensures that the dimensional increase of each elastic element 14 in the direction perpendicular to the axial direction of the rod 11 is consistent when it is compressed, thus maximizing the contact points between the elastic element 14 and the reverse osmosis membrane.
[0054] Please continue reading. Figure 3 In some embodiments, a separator 16 is provided between two adjacent elastic elements 14.
[0055] Among them, the strength of the separator 16 is higher than that of the elastic member 14. By setting the separator 16 between two adjacent elastic members 14, it can be ensured that the direction of the compressive force on each elastic member 14 when it is squeezed is along the axial direction of the rod 11.
[0056] Please refer to the following: Figure 1 , Figure 2 and Figure 3 In some embodiments, the reverse osmosis membrane disassembly device 1 further includes a support portion 17 and a support portion 18. The support portion 18 is disposed on the support portion 17 and has a first end 181 and a second end 182 opposite to each other. A rod 11 passes through the support portion 18, with both ends of the rod 11 passing through the first end 181 and the second end 182, respectively. A movable member 13 is located on the side of the first end 181 away from the second end 182, and the rod 11 is rotatable relative to the support portion 18.
[0057] The support part 17 may be equipped with rollers 171 to facilitate the movement of the support part 17.
[0058] The support part 18 can extend along the axial direction of the rod 11. The rod 11 passes through the support part 18 and can limit the rod 11. Specifically, the support part 18 restricts the five degrees of freedom of the rod 11, so that the limiting rod 11 can only rotate along its own axial direction.
[0059] In addition, the first end 181 may be located on the outside of the support portion 17, and the second end 182 may be located on the inside or outside of the support portion 17, without limitation.
[0060] Please continue reading. Figure 1 , Figure 2 and Figure 3 In some embodiments, the support portion 18 is movably disposed on the bearing portion 17, and the support portion 18 is movable along the axial direction of the rod 11.
[0061] The support part 18 can move along the axial direction of the rod 11, which can drive the rod 11 to move along the axial direction of the rod 11.
[0062] In this embodiment, the reverse osmosis membrane disassembly device 1 is aligned with the opening of the membrane housing, and then the support part 18 is moved along the axial direction of the rod 11 and the rod 11 is moved synchronously, so that part of the rod 11 is inserted into the membrane housing, and the limiting member 12, the elastic member 14 and the movable member 13 follow the rod 11 to move into the membrane housing.
[0063] The support 18 moves in the opposite direction along the axial direction of the rod 11, causing the rod 11 to be pulled out from the opening of the membrane housing. At this time, because the elastic element 14 is tightly attached to the reverse osmosis membrane, the elastic element 14 causes the reverse osmosis membrane to move when it moves. That is, when the elastic element 14 is pulled out from the opening of the membrane housing, it causes the reverse osmosis membrane to move.
[0064] Please refer to it again. Figure 3 In some embodiments, the outer surface of the second end 182 is configured as a rack 1821, and the bearing portion 17 is rotatably provided with a gear 19 that meshes with the rack 1821. The gear 19 rotates to drive the support portion 18 to move axially along the rod 11.
[0065] In this embodiment, the reverse osmosis membrane disassembly device 1 is aligned with the opening of the membrane housing. The gear 19 rotates, causing the rack 1821 at the second end 182 to move axially along the rod 11, so that the support part 18 moves axially along the rod 11 and drives the rod 11 to move synchronously, so that part of the rod 11 extends into the membrane housing, and the limiting member 12, the elastic member 14 and the movable member 13 follow the rod 11 to move into the membrane housing.
[0066] The gear 19 rotates in the opposite direction, causing the rack 1821 at the second end 182 to move in the opposite direction along the axial direction of the rod 11, which in turn causes the support part 18 to move in the opposite direction along the axial direction of the rod 11, causing the rod 11 to be pulled out from the opening of the membrane housing. At this time, since the elastic element 14 is in close contact with the reverse osmosis membrane, the elastic element 14 moves and drives the reverse osmosis membrane to move. That is, when the elastic element 14 is pulled out from the opening of the membrane housing, it drives the reverse osmosis membrane.
[0067] Please continue reading. Figure 3 In some embodiments, gear 19 is provided with handle 20.
[0068] Gear 19 is equipped with handle 20, which allows staff to manually control the rotation of gear 19 by manually controlling handle 20.
[0069] Although the present invention has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of the invention. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict.
