Description

Technical Field

[0001] The utility model relates to the field of disassemblers, in particular to an RO membrane shell end cover disassembler. Background Art

[0002] RO membrane, or reverse osmosis membrane, is an indispensable component in contemporary water treatment technology. It is widely used in the core links of industrial and civil water systems. As an efficient water treatment method, RO membrane, with its unique separation properties, can accurately remove various impurities such as dissolved salts, colloids, microorganisms, and organic matter from water, converting tap water or other water sources into pure water.

[0003] However, RO membranes can become contaminated and worn over time, affecting their filtration performance. Furthermore, RO membranes are also subject to mechanical stress, which can cause a gradual decline in performance. Therefore, regular replacement of RO membranes is necessary to maintain water quality. The filtration equipment using RO membrane mainly includes an RO membrane shell 1, an end cover 2 and an internal connecting column 3. The internal connecting column 3 is hollow and rotates coaxially with the end cover 2. The RO membrane is installed on the internal connecting column 3. The RO membrane shell 1 is sleeved on the internal connecting column 3 and the outside of the end cover 2, and the end of the internal connecting column 3 away from the end cover 2 is threadedly connected to the RO membrane shell 1. The internal connecting column 3 passes through the end cover 2 and is opened with a water outlet 7. A retaining ring is fixed in the RO membrane shell 1. The side of the end cover 2 facing away from the water outlet 7 is fitted with the retaining ring, and a plurality of fixing bolts are provided on the side of the end cover 2 facing away from the retaining ring. The fixing bolts pass through the end cover 2 and are threadedly connected to the retaining ring to fix the end cover 2. When filtering liquid, the liquid passes through the RO membrane on the internal connecting column 3 and is discharged from the water outlet 7. The water outlet 7 of the internal connecting column 3 is opened with an internal thread.

[0004] With respect to the above-mentioned related technologies, when removing the end cover 2, all the fixing bolts must be removed first, and then the inner connecting column 3 must be rotated) to separate the inner connecting column 3 from the RO membrane shell 1. However, since the end cover 2 is located on the inner side of the RO membrane shell 1, when removing the end cover 2, a disassembly tool must be inserted into the RO membrane shell 1 and the inner connecting column 3 must be rotated by the disassembly tool. Since the inner connecting column 3 is long and the outer diameter of the end cover 2 is smaller than the inner diameter of the membrane shell 1, if the inner connecting column 3 shakes radially during the disassembly process, it is easy to cause damage to the inner connecting column 3, which requires more time to disassemble and the disassembly efficiency is low. Therefore, a disassembly device is urgently needed to improve the efficiency of disassembly and assembly of the end cover 2. Utility Model Content

[0014] By adopting the above technical solution, the connecting rod fits with the inner wall of the shaft hole when inserted into the shaft hole, so that the turning handle can better drive the worm to rotate, reducing the rotation time and thus improving the rotation efficiency.

[0015] Optionally, an inlet hole portion is provided at one end of the disassembly column away from the screw head. The inlet hole portion is conical, and the diameter of the inlet portion gradually decreases in the direction away from the screw head.

[0016] By adopting the above technical solution, the hole entrance portion is conical, so that the disassembly column can pass through the sleeve hole and the rotary hole more conveniently, reducing the end cover disassembly time and improving the end cover disassembly efficiency.

[0034] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0035] The embodiment of the present application discloses an RO membrane shell end cover remover.

[0036] Example 1:

[0037] Reference Figure 1 and Figure 2 A dismantling device for the end cover 2 of an RO membrane shell 1 includes a dismantling rod 4, which includes a screw head 41, a dismantling column 42 and two ejection plates 5. The dismantling column 42 is coaxially fixed with the screw head 41. During the dismantling process, the screw head 41 is first rotated into the water outlet 7. Because the screw head 41 is adapted to the internal thread of the water outlet 7 of the internal connecting column 3, the screw head 41 is threadedly connected to the water outlet 7, making the connection between the screw head 41 and the water outlet 7 more secure and not easy to fall off.

[0038] Reference Figure 3 and Figure 4 , the two ejector plates 5 are cross-fixed, and the same set of holes 56 are opened in the middle of the two ejector plates 5. An outer baffle 52 is vertically fixed to one end of the ejector plate 5 along the length direction. An inner baffle 51 is also provided on the side of the ejector plate 5 where the outer baffle 52 is provided. The inner baffle 51 is located on the side of the outer baffle 52 close to the hole 56. The inner baffle 51 is slidably connected to the ejector plate 5 in the direction away from or close to the outer baffle 52. An elastic member 53 is provided between the outer baffle 52 and the inner baffle 51. The elastic member 53 is used to push the inner baffle 51 away from the outer baffle 52. The end of the disassembly column 42 away from the screw head 41 is provided with an inlet The hole portion 421 and the inlet hole portion 421 are conical, and the diameter of the inlet hole portion gradually decreases in the direction away from the screw head 41, so that the disassembly column 42 can pass through the sleeve hole during disassembly, reducing the disassembly time. Then the disassembly column 42 is passed through the sleeve hole 56, and the inner baffle 51 and the outer baffle 52 clamp the ejector plate 5 on the membrane shell 1. The inner baffle 51 and the outer baffle 52 are both provided with a friction plate 511 on the side close to each other. The friction plate 511 is provided with a plurality of anti-slip grooves on the side away from the corresponding inner baffle 51 or the outer baffle 52, which is beneficial to increase the friction force of the contact surface with the membrane shell 1 and make the ejector plate 5 more firmly connected.

[0039] Reference Figure 3 and Figure 4 The outer baffle 52 is provided with a limit rod 55 for positioning the inner baffle 51. The limit rod 55 is set along the sliding direction of the inner baffle 51, and the limit rod 55 passes through the outer baffle 52 and is fixedly connected to the inner baffle 51. When the limit rod 55 moves, the inner baffle 51 is driven to move. A fixing nut 54 is provided on the side of the outer baffle 52 facing away from the inner baffle 51. The fixing nut 54 is threadedly connected to the limit rod 55 and fits against the side of the outer baffle 52 facing away from the inner baffle 51. When rotating, the fixing nut 54 exerts a pulling force on the limit rod 55 to move the inner baffle 51 in the direction close to the outer baffle 52. At this time, the inner baffle 51 and the outer baffle 52 cooperate to clamp the membrane shell in position. A buffer pad 57 is fixed on the side of the ejector plate 5 close to the inner baffle 51, which is beneficial to reduce the friction of the ejector plate 5 on the membrane shell 1 during the disassembly process, reduce the wear on the membrane shell 1 caused by the disassembly process, and increase the protection of the membrane shell 1.

[0040] Reference Figure 5The worm 61 is connected to the ejector plate 5 at one end thereof and is engaged with the worm gear 62. When the worm 61 rotates, the worm gear 61 is engaged with the worm gear 62. When the worm 61 rotates, the worm gear 61 is driven by the worm gear 62. When the worm 61 rotates, the worm gear 61 is driven by the worm gear 62. When the worm 61 rotates, the worm gear 61 is driven by the worm gear 62. When the worm 61 rotates, the worm gear 61 is driven by the worm gear 62. When the worm 61 rotates, the worm gear 61 is driven by the worm gear 62. When the worm 61 rotates, the worm gear 61 is driven by the worm gear 62. When the worm 61 rotates, the worm gear 61 is driven by the worm gear 62. When the worm 61 rotates, the worm gear 61 is driven by the worm gear 62. When the worm 61 rotates, the worm gear 61 is driven by the worm gear 62.

[0041] The implementation principle of the RO membrane shell 1 end cover 2 remover of the embodiment of the present application is as follows: when removing the end cover 2, the screw head 41 is threadedly connected to the water outlet 7, the disassembly column 42 passes through the sleeve hole 56, the inner baffle 51 and the outer baffle 52 cooperate to make the ejection plate 5 stuck on the membrane shell 1, and the fixing nut 54 is screwed to reduce the gap between the inner baffle 51 and the outer baffle 52, and then the disassembly column 42 is passed through the rotating hole 63, and the rotating hole 63 is adapted to the disassembly column 42. In this way, the rotating handle 62 is rotated, and the rotating handle 62 drives the worm 61 to rotate, and then drives the worm gear and the disassembly rod 4 to rotate, so that the connection structure between the inner connecting column 3 and the membrane shell 1 is separated, and the end cover 2 is disassembled. This disassembly method is more labor-saving and conducive to improving the disassembly efficiency of the end cover 2.

[0042] Example 2:

[0043] Reference Figure 6 The difference between this embodiment and embodiment 1 is that the rotating mechanism that drives the runner 6 to rotate is different. The rotating mechanism includes a connecting column 64 and a ring 65. The connecting column 64 is located on the side of the runner 6 away from the rotating hole 63. One end of the connecting column 64 is fixedly connected to the runner 6, and the other end is fixedly connected to the ring 65. In this way, when removing the end cover 2, the ring 65 is rotated. At this time, the ring 65 drives the runner 6 to rotate, the runner 6 drives the connecting rod to rotate, and the connecting column 64 drives the inner connecting column 3 to rotate, so that the connection structure between the inner connecting column 3 and the membrane shell 1 is separated. In this way, the process of removing the end cover 2 by rotating the ring 65 is more labor-saving and simple, which can effectively improve the removal efficiency of the end cover 2.

[0044] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
