The reverse osmosis membrane element is the core component of this technology. After long-term use, its desalination efficiency will gradually decrease. Therefore, in order to ensure the effect of reverse osmosis technology, the reverse osmosis membrane element needs to be replaced regularly.

[0003] In the related art, a Chinese patent with the authorization announcement number CN210389039U provides a tool for disassembling a reverse osmosis membrane element, which includes a hollow long tube, a fixed clamp hand is fixedly arranged on the hollow long tube, a movable clamp hand is rotatably arranged on the fixed clamp hand, and a push rod is movably arranged in the hollow long tube, and the push rod is rotatably connected to the power handle. When disassembling the reverse osmosis membrane element, the push rod is operated to control the opening and closing of the fixed clamp hand and the movable clamp hand, so that the fixed clamp hand and the movable clamp hand cooperate to clamp the reverse osmosis membrane element, and then the reverse osmosis membrane element is clamped and pulled out.

[0004] In the process of realizing the present application, the inventors found that there are at least the following problems in the technology: during the removal of the reverse osmosis membrane element, the fixed pliers and the movable pliers can easily scratch the surface of the reverse osmosis membrane element, causing damage to the reverse osmosis membrane element. Utility Model Content

[0020] By adopting the above technical solution, when the rotating handle drives the rotating nut and the disassembly screw rod to rotate relative to each other, the disassembly screw rod and the support frame move relative to each other.

[0021] Preferably, a hand-holding handle is rotatably provided on the rotating handle, the rotating handle and the hand-holding handle are perpendicular to each other, and the hand-holding handle and the disassembly rod are parallel to each other.

DETAILED DESCRIPTION

[0035] The following is combined with Figure 1-7 This application is described in further detail.

[0036] The present application embodiment discloses a novel disassembly device for a reverse osmosis membrane element. Figures 1 to 7, including a disassembly screw 6, and a disassembly head 61 is installed on the end wall of one end of the disassembly screw 6. The outer wall of the disassembly head 61 is provided with a disassembly thread 611, and the disassembly thread 611 is used to be threadedly connected with the internal thread joint 721. The disassembly head 61 is detachably provided with a plug rod 2, and a hollow tube 1 is sleeved on the plug rod 2. The drive assembly 3 is installed on the plug rod 2 and the hollow tube 1, and the drive assembly 3 is used to make the plug rod 2 and the hollow tube 1 move relative to each other. A plug connector 21 is installed on the end of the plug rod 2 away from the disassembly head 61, and a rubber expansion sleeve 4 is installed on the plug connector 21. The rubber expansion sleeve 4 is sleeved on the plug rod 2 and the hollow tube 1 together, and there is an expansion gap 41 between the plug rod 2 and the rubber expansion sleeve 4. The expansion gap 41 is for the hollow tube 1 to move, and the hollow tube 1 is used to abut against the rubber expansion sleeve 4. The reverse osmosis membrane assembly 7 includes a reverse osmosis membrane shell 71, a reverse osmosis membrane end cover 72 and a reverse osmosis membrane element 73. The reverse osmosis membrane element 73 is arranged in the reverse osmosis membrane shell 71, and a water outlet 731 is arranged in the reverse osmosis membrane element 73. The reverse osmosis membrane end cap 72 is arranged in the reverse osmosis membrane shell 71, and an internal thread joint 721 is installed on the side of the reverse osmosis membrane end cap 72 away from the reverse osmosis membrane element 73, and an external thread plug is threadedly connected to the internal thread joint 721. A retaining ring is installed on the side of the reverse osmosis membrane end cap 72 away from the reverse osmosis membrane element 73, and the retaining ring is installed on the reverse osmosis membrane end cap 72 through a hexagonal bolt. Since the water outlet 731 of the reverse osmosis membrane element 73 is shielded by the reverse osmosis membrane end cap 72, before disassembling the reverse osmosis membrane element 73, the hexagonal bolt must be disassembled first to remove the retaining ring on the reverse osmosis membrane end cap 72, and then the external thread plug must be rotated to expose the internal thread joint 721, and then the reverse osmosis membrane end cap 72 is removed. When disassembling the reverse osmosis membrane end cap 72, the plug rod 2 is separated from the disassembly head 61, and the disassembly thread 611 on the disassembly head 61 is threadedly connected with the internal thread joint 721 on the reverse osmosis membrane end cap 72, and then the disassembly screw 6 is moved, and the disassembly screw 6 drives the reverse osmosis membrane end cap 72 to move, and then the reverse osmosis membrane end cap 72 is disassembled. After the reverse osmosis membrane end cap 72 is taken out, the reverse osmosis membrane end cap 72 is separated from the disassembly head 61. When disassembling the reverse osmosis membrane element 73, the plug connector 21 is first inserted into the water outlet 731 of the reverse osmosis membrane element 73, so that the rubber expansion sleeve 4 is located in the water outlet 731 of the reverse osmosis membrane element 73, and then the driving component 3 is used to make the plug rod 2 and the hollow tube 1 move relative to each other, so as to achieve the effect of the hollow tube 1 moving along the expansion gap 41. When the hollow tube 1 is gradually inserted into the expansion gap 41, the rubber expansion sleeve 4 is deformed under the action of the hollow tube 1, so that the rubber expansion sleeve 4 is pressed against the inner wall of the water outlet 731, increasing the friction between the outer wall of the rubber expansion sleeve 4 and the inner wall of the water outlet 731, so that the rubber expansion sleeve 4 and the reverse osmosis membrane element 73 are not easy to move relative to each other.When the rubber expansion sleeve 4 is in contact between the hollow tube 1 and the reverse osmosis membrane element 73, the plug-in rod 2 is connected to the disassembly screw 6, and then the disassembly screw 6 is moved, the disassembly screw 6 drives the plug-in rod 2 to move, the plug-in rod 2 drives the rubber expansion sleeve 4 to move, and the rubber expansion sleeve 4 drives the reverse osmosis membrane element 73 to move, so as to achieve the effect of disassembling the reverse osmosis membrane element 73. The surface of the reverse osmosis membrane element 73 is not easily scratched, and the damage of the reverse osmosis membrane element 73 is reduced.

[0037] In order to make the plug rod 2 and the hollow tube 1 move relative to each other, refer to Figure 1 and Figure 2 The driving assembly 3 includes a driving nut 31 and a driving screw 32. The driving screw 32 is welded to the end of the plug rod 2 away from the plug connector 21, and the driving nut 31 is welded to the end of the hollow tube 1 away from the plug connector 21. The driving nut 31 is sleeved on the driving screw 32, and the driving nut 31 is threadedly connected with the driving screw 32. When the driving nut 31 and the driving screw 32 rotate relative to each other, the driving nut 31 and the driving screw 32 move relative to each other, and then the plug rod 2 and the hollow tube 1 move relative to each other.

[0038] In order to make the plug-in rod 2 and the disassembly screw 6 detachable, refer to Figures 1 to 4 , a first connecting sleeve 321 is sleeved on the driving screw 32, and the first connecting sleeve 321 is threadedly connected to the driving screw 32. A second connecting sleeve 612 is sleeved on the disassembly head 61, and the second connecting sleeve 612 is threadedly connected to the disassembly head 61. The first connecting sleeve 321 and the second connecting sleeve 612 are integrally formed. When the second connecting sleeve 612 is installed on the disassembly head 61 and the first connecting sleeve 321 is installed on the driving screw 32, the disassembly screw 6 and the driving screw 32 are connected together.

[0039] In order to facilitate the removal of the screw rod 6, refer to Figures 1 to 3, a support frame 5 is provided on the disassembly screw rod 6, a plurality of support legs 52 are installed on the side of the support frame 5 facing the reverse osmosis membrane shell 71, and a rubber layer 521 is installed on the side of the support leg 52 away from the support frame 5. A through hole 51 is provided on the support frame 5, the disassembly screw rod 6 is inserted into the through hole 51, and the outer wall of the disassembly screw rod 6 is threadedly connected with the inner wall of the through hole 51. A rotating nut 62 is installed on the side of the support frame 5 away from the reverse osmosis membrane shell 71, and the rotating nut 62 is rotatably connected to the support frame 5. The support frame 5 is sleeved on the disassembly screw rod 6, and the rotating nut 62 is threadedly connected to the disassembly screw rod 6. A rotating handle 621 is installed on the upper side wall of the rotating nut 62, and a hand-held handle 622 is rotatably connected to the rotating handle 621, the rotating handle 621 and the hand-held handle 622 are perpendicular to each other, and the hand-held handle 622 and the disassembly rod are parallel to each other. During the process of disassembling the reverse osmosis membrane end cap 72, after the disassembly head 61 is connected to the internal thread joint 721 on the reverse osmosis membrane end cap 72, the support frame 5 and the rotating nut 62 are sleeved together on the disassembly screw 6, and then the support frame 5 and the rotating nut 62 are synchronously rotated relative to the disassembly screw 6, so that the support frame 5 and the rotating nut 62 move together along the disassembly screw 6. During the process of disassembling the reverse osmosis membrane element 73, after the disassembly head 61 is connected to the driving screw 32, the support frame 5 and the rotating nut 62 are sleeved together on the disassembly screw 6, and then the support frame 5 and the rotating nut 62 are synchronously rotated relative to the disassembly screw 6, so that the support frame 5 and the rotating nut 62 move together along the disassembly screw 6. When the rubber layer 521 on the support leg 52 abuts against the reverse osmosis membrane shell 71, the staff drives the rotating handle 621 by rotating the hand-held handle 622, so that the rotating handle 621 drives the rotating nut 62 to rotate relative to the support frame 5, thereby causing the disassembly screw 6 to move relative to the support frame 5 and the driving nut 31.

[0040] refer to Figures 1 to 7The disassembly process of the reverse osmosis membrane assembly 7 is as follows: the first step is to remove the hexagonal bolt to remove the retaining ring on the reverse osmosis membrane end cover 72, and then rotate the external thread plug to expose the internal thread joint 721. The second step is to separate the disassembly head 61 from the second connecting sleeve 612, and thread the disassembly thread 611 on the disassembly head 61 with the internal thread joint 721 on the reverse osmosis membrane end cover 72. The third step is to sleeve the support frame 5 and the rotating nut 62 together on the disassembly screw 6, and then make the support frame 5 and the rotating nut 62 rotate relative to the disassembly screw 6 synchronously, so that the support frame 5 and the rotating nut 62 move synchronously along the disassembly screw 6, so that the rubber layer 521 on the support leg 52 abuts against the reverse osmosis membrane shell 71. The fourth step is that the staff rotates the handheld handle 622 to make the rotating nut 62 rotate relative to the support frame 5, and then the disassembly screw 6 drives the reverse osmosis membrane end cover 72 to move, and the reverse osmosis membrane end cover 72 is disassembled. Step 5: After the reverse osmosis membrane end cap 72 is removed, separate the reverse osmosis membrane end cap 72 from the disassembly head 61. Step 6: Insert the plug connector 21 into the water outlet 731 of the reverse osmosis membrane element 73, so that the rubber expansion sleeve 4 is located in the water outlet 731 of the reverse osmosis membrane element 73. Step 7: Make the driving nut 31 and the driving screw 32 rotate relative to each other, and gradually insert the hollow tube 1 into the expansion gap 41 until the rubber expansion sleeve 4 is tightly pressed between the hollow tube 1 and the reverse osmosis membrane element 73. Step 8: Connect the driving screw 32 and the disassembly screw 6 together through the first connecting sleeve 321 and the second connecting sleeve 612. Step 9: The support frame 5 and the rotating nut 62 are jointly sleeved on the disassembly screw 6, and then the support frame 5 and the rotating nut 62 are synchronously rotated relative to the disassembly screw 6, so that the support frame 5 and the rotating nut 62 move together along the disassembly screw 6, so that the rubber layer 521 on the support leg 52 abuts against the reverse osmosis membrane shell 71. In the tenth step, the staff rotates the hand-held handle 622 to make the rotating nut 62 and the support frame 5 rotate relative to each other, and then the disassembly screw 6 drives the reverse osmosis membrane element 73 to move, and the reverse osmosis membrane element 73 is disassembled.

[0041] The implementation principle of a novel disassembly device for a reverse osmosis membrane element in the embodiment of the present application is as follows: insert the plug connector 21 into the water outlet 731 of the reverse osmosis membrane element 73, so that the rubber expansion sleeve 4 is located in the water outlet 731 of the reverse osmosis membrane element 73. The plug rod 2 and the hollow tube 1 are moved relative to each other, so that the hollow tube 1 moves along the expansion gap 41. When the hollow tube 1 is gradually inserted into the expansion gap 41, the rubber expansion sleeve 4 is deformed under the action of the hollow tube 1, so that the rubber expansion sleeve 4 is pressed against the inner wall of the water outlet 731, and the friction between the outer wall of the rubber expansion sleeve 4 and the inner wall of the water outlet 731 is increased, so that the rubber expansion sleeve 4 and the reverse osmosis membrane element 73 are not easy to move relative to each other, and the rubber expansion sleeve 4 is not easy to scratch the reverse osmosis membrane element 73. When the plug rod 2 is interference fit with the reverse osmosis membrane element 73 through the rubber expansion sleeve 4 and the hollow tube 1, the reverse osmosis membrane element 73 is driven to move by moving the plug rod 2, so as to achieve the effect of disassembling the reverse osmosis membrane element 73. The use of the rubber expansion sleeve 4 reduces the risk of scratching the surface of the reverse osmosis membrane element 73 , thereby reducing the possibility of damage to the reverse osmosis membrane element 73 .

[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
