Description

Technical Field

[0001] This utility model relates to the field of reverse osmosis membrane technology, and in particular to a reverse osmosis membrane installation and disassembly device. Background Technology

[0002] Reverse osmosis membranes are a commonly used wastewater treatment and water softening purification process. Reverse osmosis membranes are susceptible to clogging due to water quality issues or need replacement after reaching their lifespan. In some large treatment plants, multiple reverse osmosis membranes need to be installed in the pressure vessel. Typically, installing reverse osmosis membranes requires manual pushing of each membrane into the mounting shell sequentially. Since each membrane weighs several kilograms, and considering the friction between the membrane and the mounting shell, a very large pushing force is required during installation, especially for the last few membranes. Removing the membranes from the mounting shell is also very difficult. Therefore, a reverse osmosis membrane installation and removal device is proposed. Utility Model Content

[0003] This utility model provides a reverse osmosis membrane installation and disassembly device to solve at least one of the above-mentioned technical problems.

[0004] This utility model provides a reverse osmosis membrane installation and disassembly device, including a connecting component, an abutment component, a locking component, and a reverse osmosis membrane, wherein...

[0005] When installing or removing the reverse osmosis membrane, the connecting assembly is installed inside the mounting shell of the reverse osmosis membrane. One end of the connecting assembly is connected to the abutment member, and the other end passes through the locking member. The connecting assembly is used to define the installation position of the reverse osmosis membrane during installation.

[0006] The abutment is used to pull the reverse osmosis membrane during installation or removal;

[0007] The locking element is installed at one end of the mounting housing and is used to limit the position of the reverse osmosis membrane during installation.

[0008] In one embodiment, the connecting assembly includes a first pull rod and a first screw, one end of the first pull rod being connected to the abutment, the other end of the first pull rod being detachably connected to the first screw, and the end of the first screw away from the first pull rod being detachably connected to a handle.

[0009] In one embodiment, the connecting assembly further includes multiple second pull rods and multiple second screws, wherein the end of the first screw away from the handle is sequentially connected to multiple second screws, multiple second pull rods, and the first pull rod.

[0010] In one embodiment, the locking member is sleeved on the first screw, and the internal thread of the locking member is engaged with the external thread of the first screw.

[0011] In one embodiment, the mounting shell is cylindrical, the width of the abutment is smaller than the inner diameter of the mounting shell, and the width of the abutment is larger than the inner diameter of the through hole at the center of the reverse osmosis membrane.

[0014] In one embodiment, the diameter of the connecting component is smaller than the inner diameter of the through-hole at the center of the reverse osmosis membrane.

[0015] Compared with the prior art, the advantages of this utility model are that, when installing the reverse osmosis membrane, the connecting component can be rotated and moved along the direction of the mounting shell under the action of the locking component. The movement of the connecting component drives the abutment to move, thereby moving the reverse osmosis membrane toward the locking component, so that the reverse osmosis membrane finally comes into close contact with the locking component, thus achieving rapid installation of the reverse osmosis membrane; when disassembling the reverse osmosis membrane, the connecting component and the abutment can cooperate, and the connecting component drives the abutment to pass through the entire mounting shell, thereby pulling out the reverse osmosis membrane inside the mounting shell.

[0024] The present invention will be further described below with reference to the accompanying drawings.

[0025] Please refer to Figures 1 to 5 This utility model provides a reverse osmosis membrane installation and removal device, including: a connecting component 1, an abutment 2, a locking component 3, and a reverse osmosis membrane 6. During installation or removal of the reverse osmosis membrane 6, the connecting component 1 is installed inside the mounting shell 5 of the reverse osmosis membrane 6. One end of the connecting component 1 extends out of the mounting shell 5 and connects to the abutment 2, while the other end passes through the locking component 3 and connects to a handle 4. The connecting component 1 is used to limit the installation position of the reverse osmosis membrane 6 during installation. The abutment 2 is used to pull the reverse osmosis membrane 6 during installation or removal. The locking component 3 is installed at one end of the mounting shell 5 and is used to limit the position of the reverse osmosis membrane 6 during installation, preventing the reverse osmosis membrane 6 from detaching from the mounting shell 5. In this embodiment, the abutment 2 is preferably circular.

[0026] To better implement this utility model, refer to Figure 1 In one embodiment, the connecting assembly 1 includes a first pull rod 101 and a first screw 103. One end of the first pull rod 101 is connected to the abutment 2. The first pull rod 101 and the abutment 2 are detachably connected, or they can be made into an integral structure. In this embodiment, it is preferred that the first pull rod 101 and the abutment 2 are detachable, and the connection method is preferably a mating assembly. The other end of the first pull rod 101 is detachably connected to the first screw 103, and the end of the first screw 103 away from the first pull rod 101 is detachably connected to a handle 4. The first pull rod 101 and the first screw 103 are connected by a mating assembly. In this embodiment, the mating assembly includes an inner threaded hole and an outer screw. The inner threaded hole and the outer screw are respectively installed at the connecting ends of the first pull rod 101 and the first screw 103, and are connected by the thread engagement on the inner threaded hole and the outer screw.

[0027] The mating components can also be connected by spiral joints, clamps, or snap locks to ensure that the connecting component 1 installed and connected by the mating components can pass smoothly through the through hole in the center of the reverse osmosis membrane 6.

[0028] To better implement this utility model, refer to Figure 1 In one embodiment, the connecting assembly 1 further includes multiple second pull rods 102 and multiple second screws 104. The end of the first screw 103 away from the handle 4 is sequentially connected to the multiple second screws 104, the multiple second pull rods 102, and the first pull rod 101. The first screw 103 and the second screws 104 are connected by a mating assembly, the second screws 104 and the second pull rods 102 are connected by a mating assembly, and the second pull rods 102 and the first pull rods 101 are connected by a mating assembly.

[0029] When the mounting housing 5 to be installed is large, a single first screw 103 and first pull rod 101 are insufficient to meet the installation requirements of the reverse osmosis membrane 6. In this case, the entire connecting assembly 1 needs to be extended. A second screw 104 and a second pull rod 102 can be installed between the first screw 103 and the first pull rod 101, using a mating assembly connection. That is, one end of the second screw 104 has an internal threaded hole, and the other end has an external screw. Figure 5 As shown; one end of the second pull rod 102 is provided with an internal threaded hole, and the other end is provided with an external threaded rod, as shown. Figure 2 As shown. Taking the connection between the second screw 104 and the second pull rod 102 as an example, the outer screw of the second screw 104 is connected to the inner threaded hole of the second pull rod 102. Similarly, when the first screw 103 is connected to the second screw 104, only the corresponding components in the mating assembly need to be set at the connection end of the second screw 104.

[0030] In actual use, the number of second screws 104 and second pull rods 102 used is determined according to the actual length of the mounting shell 5.

[0031] To better implement this utility model, refer to Figure 1 In one embodiment, the locking member 3 is sleeved on the first screw 103, and the internal thread of the locking member 3 is engaged with the external thread of the first screw 103.

[0032] To better implement this utility model, refer to Figure 3 or Figure 4 In one embodiment, the mounting shell 5 is cylindrical, and the width of the abutment 2 is smaller than the inner diameter of the mounting shell 5, while the width of the abutment 2 is larger than the inner diameter of the through hole at the center of the reverse osmosis membrane 6. This allows the abutment 2 to pass through the mounting shell 5 under the drive of the connecting assembly 1, and to move the reverse osmosis membrane 6 fitted on the connecting assembly 1 within the mounting shell 5.

[0033] To better implement this utility model, refer to Figure 3 or Figure 4 In one embodiment, the diameter of the locking member 3 is larger than the inner diameter of the mounting shell 5, and the locking member 3 is connected to the mounting shell 5 via a disassembly and assembly assembly. To ensure that the disassembly and assembly assembly can apply an anti-rotation force to the locking member 3 during the installation of the reverse osmosis membrane 6, so that the locking member 3 will not rotate along with the mounting shell 5 when it rotates, the internal thread of the locking member 3 engages with the external thread of the first screw 103, so that the first screw 103 can move along the direction of the mounting shell 5 when it rotates, thereby driving the abutment member 2 to move along the inside of the mounting shell 5, thereby pulling the reverse osmosis membrane 6 sleeved on the connecting assembly 1 to move within the mounting shell 5. The disassembly and assembly assembly can be a clamp, a quick clamp, or a locking ring.

[0034] To better implement this utility model, refer to Figure 1In one embodiment, a protective pad is provided on the side surface of the abutment member near the mounting housing 5 to reduce damage to the reverse osmosis membrane 6 when it is pushed.

[0035] To better implement this utility model, refer to Figure 1 In one embodiment, the diameter of the connecting component 1 is smaller than the inner diameter of the through hole at the center of the reverse osmosis membrane 6.

[0036] The working principle of the reverse osmosis membrane installation and disassembly device described above is as follows:

[0037] When installing the reverse osmosis membrane 6 into the mounting housing 5, as follows Figure 3 As shown, during installation, the reverse osmosis membrane 6 will enter the mounting housing 5 through the opening on the side of the mounting housing 5 closest to the abutment member 2, as... Figure 3 As shown, reverse osmosis membrane 6 from Figure 3 The device enters from the left end of the mounting shell 5 and, under the action of the installation and disassembly device, gradually moves within the mounting shell 5 to reach the final installation position. Based on the length of the mounting shell 5, select the number of second screws 104 and second pull rods 102, and connect the first screw 103, second screw 104, second pull rod 102 and first pull rod 101 in sequence. Install the locking member 3 at one end of the mounting shell 5, so that one end of the first screw 103 of the connecting assembly 1 extends into the mounting shell 5, passes through the locking member 3, and connects to the handle 4. After the multiple reverse osmosis membranes 6 to be installed are sleeved on the connecting assembly 1, connect one end of the first pull rod 101 to the abutment member 2. Then, rotate the handle 4, and the handle 4 drives the first screw 103 to rotate. Under the action of the external thread of the first screw 103 and the internal thread of the locking member 3, the first screw 103 can gradually move to the outside of the mounting shell 5, thereby driving the entire connecting assembly 1 to move to the outside of the mounting shell 5. The connecting assembly 1 will drive the abutment member 2 to move, and the abutment member 2 will push the reverse osmosis membrane 6 to move along the mounting shell 5 and gradually approach one end of the locking member 3. Once the reverse osmosis membrane 6 is in contact with the locking member 3, the installation of the reverse osmosis membrane 6 is complete. This process is suitable for installing a small number of reverse osmosis membranes 6, allowing for installation in one go.

[0038] If a large number of reverse osmosis membranes 6 need to be installed inside the mounting housing 5, and manual installation is inconvenient, a portion of the reverse osmosis membranes 6 can be installed first using the above process. Then, turn the handle 4 back, causing the first screw 103 to drive the entire connecting assembly 1 back into the mounting housing 5. At this time, the abutment 2 gradually returns to the other end of the mounting housing 5. The position of the installed reverse osmosis membranes 6 will not change. Remove the abutment 2, and then put the reverse osmosis membranes 6 onto the connecting assembly 1 again. After installing the abutment 2, turn the handle 4 again, causing the first screw 103 to move outward, thereby moving the entire connecting assembly 1 and the abutment 2. The abutment 2 pushes the reverse osmosis membranes 6 into the mounting housing 5. After installation, remove the abutment 2, the locking part 3, and the connecting assembly 1.

[0039] When removing the reverse osmosis membrane 6 from the mounting housing 5, as follows Figure 4 As shown, during disassembly, the reverse osmosis membrane 6 will detach from the mounting housing 5 near the handle 4. The connecting assembly 1 is inserted into the through hole at the center of the reverse osmosis membrane 6 inside the mounting housing 5. A stop member 2 is connected to one end of the first pull rod 101 of the connecting assembly 1, and a handle 4 is connected to one end of the first screw 103. The worker pulls the handle 4, which moves the connecting assembly 1. The connecting assembly 1 moves the stop member 2, which in turn pushes the reverse osmosis membrane 6 inside the mounting housing 5 toward the handle 4 and out of the mounting housing 5. When the stop member 2 enters from one end of the mounting housing 5 and exits from the other end, all the reverse osmosis membranes 6 inside the mounting housing 5 are removed.

[0040] Alternatively, a portion of the reverse osmosis membrane 6 near both ends of the mounting shell 5 can be removed in advance. Because the mounting shell 5 is quite long, the internal portion of the reverse osmosis membrane 6 is far from the outlets at both ends of the mounting shell 5. The friction between the reverse osmosis membrane 6 and the mounting shell 5 makes removal difficult. In this case, a connecting component 1 can be inserted into the through-hole at the center of the remaining reverse osmosis membrane 6. A stopper 2 is connected to one end of the connecting component 1, and the other end passes through a locking component 3 and is connected to the handle 4. The locking component 3 is then fixed to the mounting shell 5. The handle 4 is then rotated to allow the connecting component to... The first screw 103 of 1 cooperates with the locking part 3, driving the entire connecting assembly 1 to move towards the handle 4. The abutment 2 connected to the connecting assembly 1 gradually approaches the reverse osmosis membrane 6 inside the mounting shell 5. Continue to rotate the handle 4 until the abutment 2 gradually pushes the reverse osmosis membrane 6 to the opening of the mounting shell 5 near the handle 4. Remove the locking part 3, and you can directly pull the handle 4, thereby driving the connecting assembly 1 and the abutment 2 to move out of the mounting shell 5 in sequence, so as to remove the reverse osmosis membrane 6 sleeved on the connecting assembly 1 from the mounting shell 5.

[0041] 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. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
