Description

Technical Field

[0001] This utility model belongs to the field of reverse osmosis membrane disassembly and assembly technology, specifically relating to a reverse osmosis membrane disassembly device based on side wing elastic claws. Background Technology

[0002] Water purification and recycling are crucial for supporting modern industrial production, municipal water supply, and ecological environmental protection. With the increasing severity of global water scarcity and the growing complexity of water pollution, efficient and stable water treatment technologies have become a focus of research and application in various countries. Among these, reverse osmosis technology, with its highly efficient removal of impurities such as ions, organic matter, and microorganisms from water, has been widely used in seawater desalination, brackish water desalination, industrial pure water production, and wastewater treatment and reuse, becoming one of the indispensable core technologies in the current water treatment industry. The reverse osmosis membrane, as the core functional component of the reverse osmosis system for water purification, directly determines water treatment efficiency, effluent quality, and equipment operating costs. During long-term operation, pollutants such as colloids, microorganisms, and inorganic salt scale gradually accumulate on the surface of the reverse osmosis membrane, leading to a decrease in membrane flux and desalination rate, affecting the stable operation of the system. Therefore, to maintain the high efficiency of the reverse osmosis system, the reverse osmosis membrane needs to be disassembled regularly for cleaning and maintenance or replacement with new membrane elements. The dismantling of reverse osmosis membranes has become a crucial step in ensuring the continuous and stable operation of water treatment systems. The ease of operation, safety, and efficiency of this process directly affect the maintenance costs and operational benefits of the entire water treatment system.

[0003] In current reverse osmosis membrane disassembly operations, the performance of the disassembly tools is a key factor affecting the quality of the operation. In existing technologies, a sealing ring is typically used to achieve a tight seal between the membrane element and the membrane housing to ensure pressure stability during the reverse osmosis process. This results in a relatively large bonding force between the two. Current disassembly methods often rely on manual pulling of the membrane element, which is not only labor-intensive and inefficient, but also prone to damage to the sealing ring due to uneven force or improper operation during the pulling process, increasing the maintenance cost of the membrane element. Some disassembly processes use chucks, which may have a limited number of chucks or uneven distribution around the circumference. This leads to an imbalance of force on the membrane element surface when gripping it, easily causing localized stress concentration and resulting in cracks, deformation, and other damage to the membrane element, affecting the cost of reusing or replacing it. Furthermore, the depths of reverse osmosis membrane housings vary depending on the model and specifications. Existing disassembly tools mostly have fixed rod lengths, which cannot be flexibly adjusted according to the membrane housing depth. This results in poor tool versatility, requiring multiple tool specifications for membrane housings of different depths, increasing equipment investment costs and management difficulty. Therefore, there is an urgent need for a reverse osmosis membrane disassembly device based on side-wing elastic claws. Utility Model Content

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0021] like Figures 1 to 4As shown, this utility model discloses a reverse osmosis membrane disassembly device based on side-wing elastic claws. The reverse osmosis membrane end is provided with a disassembly groove. The device includes a disassembly component 1, a gripping component 3, and multiple extension components 2 connecting the disassembly component 1 and the gripping component 3. The disassembly component 1 includes a first tube 11 with multiple slots 12 evenly distributed around its outer periphery. These slots 12 provide space for the claws 4 and also limit their range of motion. A fixing seat 14 and a rotating shaft 13 are fixedly mounted on the inner wall of the first tube 11. The fixing seat 14 mainly supports and fixes the compression sleeve. 15. To ensure the stability of the compression sleeve 15 during operation, the rotating shaft 13 acts as a hinge to the jaw 4, allowing the jaw 4 to rotate around it and achieve opening and closing actions. A compression sleeve 15 is provided on one side of the fixed base 14. A jaw 4 matching the disassembly groove is hinged to the outer periphery of the rotating shaft 13. The jaw 4 is located within the slot 12. A compression rod 17 is hinged to the middle of the jaw 4 and inserted into the compression sleeve 15. A spring 16 is provided between the compression rod 17 and the compression sleeve 15. When the jaw 4 is subjected to an external radial force, the compression rod 17 slides into the compression sleeve 15. At this time, the spring 16 is compressed, and the jaw 4 retracts into the slot 12, facilitating the opening and closing of the first tube body. 11 is successfully inserted into the end of the reverse osmosis membrane. When the external radial force disappears and the end of the clasp 4 reaches the disassembly groove, under the elastic force of the spring 16, the compression rod 17 will be ejected outward from the compression sleeve 15, thereby causing the clasp 4 to open outward until the clasp 4 abuts against the inner wall of the slot 12, completing the maximum opening and thus firmly gripping the reverse osmosis membrane. One end of the first tube 11 has a threaded hole 5. The extension assembly 2 includes a second tube 21. One end of the second tube 21 is provided with a threaded section 6 that matches the threaded hole 5, and the other end has a threaded hole 5. The number of clasps 4 matches the number of slots 12. The extension assembly 2 is designed to accommodate membrane housings of different depths. By selecting different numbers of clasps 4, the extension assembly 2 can be adjusted to accommodate membrane housings of different depths. The length of the entire device can be flexibly adjusted by combining the extension components 2 to meet the disassembly requirements of membrane housings at different depths, greatly improving the applicability of the device. The gripping component 3 includes a third tube 31, one end of which is provided with a threaded section 6, and the other end is connected to a pull ring 32. The pull ring 32 provides a force application point for the operator. By pulling the pull ring 32, the operator can move the entire device and the reverse osmosis membrane gripped by the claw 4 to achieve disassembly. The first tube 11 and the second tube 21, multiple adjacent second tubes 21, and the second tube 21 and the third tube 31 are all connected by threaded connections between the threaded hole 5 and the threaded section 6.

[0022] In one specific implementation, in the reverse osmosis membrane disassembly device based on side-wing elastic claws of this utility model, the number of extension components 2 is 2 to 6, more specifically, the number of extension components 2 is 2. Of course, the specific number of extension components 2 needs to be set according to the depth and size of the membrane shell in actual use.

[0023] In one specific embodiment, in the reverse osmosis membrane disassembly device based on side-wing elastic claws of this utility model, the number of slots 12 is 4 to 12. More specifically, the number of slots 12 and claws 4 is 8. The 8 claws 4 are distributed in two groups at intervals along the axis, and the 4 claws 4 in each group are evenly distributed radially to ensure that the upper, lower, left and right radial directions can be covered. Of course, the specific number and distribution position of claws 4 and slots 12 need to be set according to the membrane shell specifications and dimensions in actual use.

[0024] As one specific implementation, in the reverse osmosis membrane disassembly device based on side-wing elastic claws of this utility model, the inner wall of the pull ring 32 is provided with an anti-slip layer. This design can increase the friction between the hand and the pull ring 32, prevent slippage during operation, and improve the stability and safety of operation.

[0025] The working principle of the reverse osmosis membrane disassembly device based on side-wing elastic claws of this utility model is as follows:

[0026] When disassembling the reverse osmosis membrane using this device, firstly, select an appropriate number of extension components 2 and a matching number of clamps 4 according to the size of the reverse osmosis membrane. Then, sequentially fix the first tube 11, multiple second tubes 21, and the third tube 31 through the threaded holes 5 and threaded sections 6 to complete the installation of the entire device. Afterward, the operator holds the pull ring 32, aligns the end of the first tube 11 with the center hole of the membrane end cap, and inserts it. During the insertion process, the clamps 4 are subjected to the radial force of the membrane end cap, the compression rod 17 slides into the compression sleeve 15, and the spring 16 is compressed. The claw 4 retracts into the slot 12, allowing the first tube 11 to be smoothly inserted into the end of the reverse osmosis membrane. When the first tube 11 reaches the end of the reverse osmosis membrane, the end of the claw 4 just extends into the disassembly groove. At this time, the radial force on the claw 4 disappears. Under the elastic force of the spring 16, the compression rod 17 is pushed out of the compression sleeve 15 by the spring 16, which in turn drives the claw 4 to open outward until the claw 4 abuts against the inner wall of the slot 12, completing the maximum opening and firmly grasping the reverse osmosis membrane. Finally, the operator pulls the pull ring 32 to disassemble and remove the reverse osmosis membrane through the claw 4.

[0027] In summary, compared with the prior art, the reverse osmosis membrane disassembly device based on side-wing elastic claws of this utility model has the following advantages and beneficial effects:

[0028] This device has a simple structure and is easy to assemble and disassemble. By using the cooperation of the claws 4 and the disassembly groove, the operator can pull the pull ring 32 to disassemble the reverse osmosis membrane without the need for direct manual pulling, which reduces labor intensity and avoids damage to the sealing ring caused by manual pulling, thus reducing maintenance costs. In addition, the multiple evenly distributed claws 4 can ensure that the membrane element is subjected to balanced force, avoid local stress concentration, prevent the membrane element from cracking, deforming and other damage, ensure the secondary use performance of the membrane element, and reduce replacement costs. Moreover, by combining multiple extension components 2, the overall length of the device can be flexibly adjusted according to the membrane shell of different depths, which has good applicability and practicality.
