Description

Technical Field

[0001] This utility model relates to the field of water purification technology, specifically a quick disassembly and assembly device for reverse osmosis membranes used in water purification. Background Technology

[0002] A reverse osmosis membrane module is a water purification device. Water passes through the reverse osmosis membrane module, which filters out impurities in the water, thus obtaining the desired clean water source. A reverse osmosis membrane is a semi-permeable membrane with a specific pore size. It can allow water molecules in the solution to pass through while retaining solutes under pressure higher than the osmotic pressure of the solution. It is the core component of a reverse osmosis membrane module. When using a reverse osmosis membrane module, the reverse osmosis membrane needs to be installed in the mounting housing.

[0003] In existing technologies, the installation and disassembly of reverse osmosis membranes present many inconveniences. Specifically, when installing a reverse osmosis membrane, due to the significant friction between the outer surface of the membrane and the inner surface of the mounting shell, multiple people are usually required to work together and continuously apply lubricating oil to reduce friction. This is not only cumbersome but also inefficient. Furthermore, when disassembling a reverse osmosis membrane, because the membrane is in close contact with the inner wall of the mounting shell, it is often difficult to separate easily, resulting in difficult, time-consuming, and labor-intensive disassembly.

[0004] Therefore, there is a need for a quick installation and removal device for reverse osmosis membranes used in water purification, which can solve the problems in the existing technology where multiple people are required to install the reverse osmosis membrane and the membrane is in close contact with the inner wall of the installation shell, making disassembly difficult. Utility Model Content

[0005] The purpose of this invention is to provide a quick disassembly and assembly device for reverse osmosis membranes used in water purification, in order to solve the problems in the prior art where multiple people are required to install the reverse osmosis membrane and the reverse osmosis membrane is in close contact with the inner wall of the mounting shell, making disassembly difficult.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quick assembly and disassembly device for a reverse osmosis membrane for water purification, comprising a membrane housing, a reverse osmosis membrane body installed inside the membrane housing, two parallel fixed rings fastened to the outer surface of the membrane housing, an L-shaped rod fixedly connected to the top of the outer surface of the fixed rings, and a quick assembly mechanism and a quick disassembly assembly respectively provided on the two L-shaped rods;

[0007] The quick-release mechanism includes a rectangular frame, which is fixedly connected to one side of the outer wall of the horizontal section of the L-shaped rod located on the left side of the outer surface of the membrane shell. A positioning rod is fixedly connected between the inner walls of both ends of the rectangular frame. A lubricant box is placed inside the rectangular frame. A positioning hole is opened on the bottom surface of the rectangular frame. Two parallel springs are fixedly connected to the outer wall of the left side of the rectangular frame. The same push plate is fixedly connected to the left side of the two springs. A push rod is fixedly connected to the center of the outer wall of the right side of the push plate. The push rod slides through the inner wall of the left side of the rectangular frame and is coaxially fixedly connected to an extrusion block.

[0008] It should be noted in the solution that the quick-release assembly includes a movable groove, which is opened through the top surface of the horizontal section of the L-shaped rod located on the right side of the outer surface of the membrane shell. A rotating rod is rotatably connected between the two end walls inside the movable groove. A disc is fixedly connected to the outer wall on the right side of the rotating rod. A screw is threaded through the center of the top surface of the disc. A top block is rotatably connected to the bottom end of the screw, and a handwheel is fixedly connected to the top end of the screw.

[0009] It is worth noting that an operating box is fixedly connected to the outer wall of the front end of the horizontal section of the L-shaped rod located on the right side of the outer surface of the membrane shell. A slider is slidably connected to the inner surface of the operating box. A spring is fixedly connected between the center of the outer wall of the front end of the slider and the inner wall of the front end of the operating box. A pull rod that slides through the outer wall of the front end of the operating box is fixedly connected to the center of the outer wall of the front end of the slider. Four insert rods distributed in a circle are fixedly connected to the outer wall of the rear end of the slider.

[0010] Furthermore, it should be noted that a limiting rod is fixedly connected to the right outer wall of the vertical section of the L-shaped rod located on the right side of the outer surface of the membrane shell, and four insertion holes are provided on the outer wall of the front end of the rotating rod, which correspond to and are adapted to the four insertion rods.

[0011] In a preferred embodiment, the two L-shaped rods are symmetrically arranged, and the discharge nozzle on the lubricant box extends out of the rectangular frame through a positioning hole.

[0012] In a preferred embodiment, the diameter of the top block is smaller than the inner diameter of the membrane shell, and the outer walls of the rear ends of the four insertion rods slide through the outer wall of the rear end of the operating box and the front wall of the inner side of the movable groove and are inserted into the corresponding insertion holes.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. By pressing the push plate, the push rod moves, causing the push rod to squeeze the extrusion block against the lubricant box. This causes the lubricant to drip onto the outer surface of the reverse osmosis membrane interface, lubricating the reverse osmosis membrane. This makes it easy for the operator to push the reverse osmosis membrane into the membrane housing. The operation is simple and does not require additional personnel to continuously drip lubricating oil onto the reverse osmosis membrane, effectively avoiding the problem of requiring multiple people to cooperate during reverse osmosis membrane installation.

[0015] 2. Pulling the lever separates the insertion rod from the insertion hole. After rotating the rotating rod, it is locked again. By turning the screw through the handwheel, the screw drives the top block to push one side of the reverse osmosis membrane, pushing the other side of the reverse osmosis membrane out of the membrane shell. This makes it easy to disassemble the reverse osmosis membrane. It is convenient to use and effectively avoids the problem of difficult disassembly caused by the reverse osmosis membrane being in close contact with the inner wall of the mounting shell.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example: Figures 1-4 As shown, this utility model provides a technical solution, including a membrane housing 1, a reverse osmosis membrane 2 installed inside the membrane housing 1, two parallel fixed rings 3 tightly fitted on the outer surface of the membrane housing 1, an L-shaped rod 4 fixedly connected to the top of the outer surface of the fixed rings 3, and quick-installation mechanism 5 and quick-release assembly 6 respectively provided on the two L-shaped rods 4.

[0023] The quick-release mechanism 5 includes a rectangular frame 51, which is fixedly connected to one side of the outer wall of the transverse section of the L-shaped rod 4 located on the left side of the outer surface of the membrane shell 1. A positioning rod 52 is fixedly connected between the inner walls of both ends of the rectangular frame 51. A lubricant box 53 is placed inside the rectangular frame 51. A positioning hole 54 is opened on the bottom surface of the rectangular frame 51. Two parallel springs 55 are fixedly connected to the outer wall of the left side of the rectangular frame 51. The same push plate 56 is fixedly connected to the left side of the two springs 55. A push rod 57 is fixedly connected to the center of the outer wall of the right side of the push plate 56. The push rod 57 slides through the inner wall of the left side of the rectangular frame 51 and is coaxially fixedly connected to an extrusion block 58.

[0024] Further as Figure 1 , Figure 2 and Figure 4 As shown, it is worth noting that the quick-release assembly 6 includes a movable groove 61, which is opened through the top surface of the transverse section of the L-shaped rod 4 located on the right side of the outer surface of the membrane housing 1. A rotating rod 62 is rotatably connected between the two end walls inside the movable groove 61. A disc 63 is fixedly connected to the outer wall of the right side of the rotating rod 62. A screw 64 is threaded through the center of the top surface of the disc 63. A top block 65 is rotatably connected to the bottom end of the screw 64, and a handwheel 66 is fixedly connected to the top end of the screw 64.

[0025] Further as Figure 4 As shown, it is worth noting that the front end of the horizontal section of the L-shaped rod 4 located on the right side of the outer surface of the membrane shell 1 is fixedly connected to the operating box 7. The inner surface of the operating box 7 is slidably connected to the slider 8. The center of the front end of the slider 8 is fixedly connected to the inner wall of the front end of the operating box 7. The center of the front end of the slider 8 is fixedly connected to the pull rod 10 that slides through the front end of the operating box 7. The rear end of the slider 8 is fixedly connected to four circumferentially distributed insert rods 11.

[0026] Further as Figure 2 and Figure 4 As shown, it is worth noting that the right outer wall of the vertical section of the L-shaped rod 4 located on the right side of the outer surface of the membrane shell 1 is fixedly connected to the limiting rod 12, and the outer wall of the front end of the rotating rod 62 is provided with four insertion holes 13 that correspond to and are adapted to the four insertion rods 11.

[0027] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that the two L-shaped rods 4 are symmetrically arranged to ensure the normal use of the quick-installation mechanism 5 and the quick-release assembly 6. The discharge nozzle on the lubricant box 53 extends out of the rectangular frame 51 through the positioning hole 54, so that when the reverse osmosis membrane 2 is installed, the lubricant can drip onto the outer surface of the reverse osmosis membrane 2 after the lubricant box 53 is squeezed.

[0028] Further as Figure 1 and Figure 4 As shown, it is worth noting that the diameter of the top block 65 is smaller than the inner diameter of the membrane housing 1, ensuring that the top block 65 can enter the interior of the membrane housing 1 to push the reverse osmosis membrane 2. The outer walls of the rear ends of the four insertion rods 11 slide through the outer walls of the rear ends of the operation box 7 and the front wall of the inner end of the movable groove 61 and are inserted into the corresponding insertion holes 13. Through the cooperation of the insertion rods 11 and the insertion holes 13, the rotation and fixation of the rotating rod 62 are controlled.

[0029] In summary: When installing the reverse osmosis membrane 2, the lubricant box 53 is inserted into the rectangular frame 51, so that the outlet of the lubricant box 53 passes through the positioning hole 54. At the same time, one side of the lubricant box 53 is aligned with one side of the positioning rod 52. Then, the interface on one side of the reverse osmosis membrane 2 is aligned with the membrane housing 1. The push plate 56 is pressed to move the push rod 57. The push rod 57 drives the extrusion block 58 to extrude the lubricant box 53, so that the lubricant drips onto the outer surface of the interface on one side of the reverse osmosis membrane 2, thus lubricating the reverse osmosis membrane 2. This makes it easy for the operator to push the reverse osmosis membrane 2 into the membrane housing 1. The operation is simple, and one person can complete the installation of the reverse osmosis membrane 2. No additional personnel are needed to continuously drip lubricating oil onto the reverse osmosis membrane 2, effectively avoiding the problem of requiring multiple people to cooperate during the installation of the reverse osmosis membrane.

[0030] When disassembling the reverse osmosis membrane 2, pull the lever 10 outward to move the slider 8. The slider 8 causes the insertion rod 11 to separate from the insertion hole 13, releasing the lock on the rotating rod 62. Rotate the rotating rod 62 downward. When the rotating rod 62 is blocked by the limit rod 12 and cannot continue to rotate, release the lever 10. Under the action of the spring 9, the insertion rod 11 is reinserted into the insertion hole 13, and the rotating rod 62 is relocked. Then, turn the handwheel 66 to drive the screw 64 to rotate. Under the action of the thread, the screw 64 drives the top block 65 into the membrane housing 1 and pushes one side of the reverse osmosis membrane 2. After pushing the other side of the reverse osmosis membrane 2 out of the membrane housing 1, it is convenient to disassemble the reverse osmosis membrane 2. It is easy to use and effectively avoids the problem of difficult disassembly caused by the reverse osmosis membrane being in close contact with the inner wall of the mounting shell.
