Abstract
Description
Technical Field
[0001] The utility model relates to the cleaning of a reverse osmosis membrane, in particular to a reverse osmosis membrane cleaning device. Background Art
[0002] Water plays an important role in our daily life and production. At the same time, water is easily polluted. For example, some substances are easily soluble in water. In order to make the polluted water meet the requirements of use, the soluble substances in the water need to be separated from the water. Reverse osmosis membrane (RO) can separate other soluble substances in water, but after a long period of filtration, the soluble substances in the water will accumulate on one side of the reverse osmosis membrane, affecting the separation of water and soluble substances.
[0003] The reverse osmosis membrane is usually placed horizontally during the cleaning process. The cleaning agent flows through the reverse osmosis membrane, flushing the surface of the reverse osmosis membrane and washing away the pollutants attached to the surface of the reverse osmosis membrane. However, after the reverse osmosis membrane is placed horizontally, under the action of gravity, the cleaning agent may not be able to completely immerse the reverse osmosis membrane, so that the part close to the upper end of the reverse osmosis membrane in the radial direction cannot be cleaned, resulting in inadequate cleaning. When the pollutants of the reverse osmosis membrane are concentrated in the upper area in the radial direction during cleaning, the cleaning effect is more difficult to guarantee.

[0039] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.
[0040] like Figures 1 to 3 As shown, a reverse osmosis membrane cleaning device corresponding to a preferred embodiment of the utility model includes a reagent container 1, a liquid conveying device 3 and a pipeline component 4.
[0041] The reagent container 1 is used to store pre-configured cleaning reagents.
[0042] The liquid delivery device 3 is used to generate power to drive the liquid to move, and it can suck the liquid in the medicine container 1 into the reverse osmosis membrane element 20 for cleaning. The liquid delivery device 3 can be, for example, a water pump. The liquid delivery device 3 has a liquid inlet end 30 and a liquid outlet end 31, and the liquid is sucked from the liquid inlet end 30 and discharged from the liquid outlet end 31.
[0043] The pipeline assembly 4 includes a first pipeline 40 connected between the medicine container 1 and the liquid inlet end 30 of the liquid delivery device 3 and a second pipeline 41 connected to the liquid outlet end 31 of the liquid delivery device 3. The first pipeline 40 and the second pipeline 41 each include at least one pipe for liquid circulation.
[0044] The second pipeline 41 includes at least one connection mechanism 43 for connecting the reverse osmosis membrane element 20. When the reverse osmosis membrane element 20 to be cleaned is connected to the second pipeline 41, the liquid in the second pipeline 41 can flow through the reverse osmosis membrane element 20. Further, the connection mechanism 43 is configured to enable the reverse osmosis membrane element 20 to be arranged vertically (i.e., along the Figure 2 When the reverse osmosis membrane element 20 is connected to the connection mechanism 43, it is kept in a vertical position. The reverse osmosis membrane element 20 has a first end 200 for the cleaning agent to enter and a second end 201 for the liquid inside the reverse osmosis membrane element 20 to be discharged, and the second end 201 is located above the first end 200. Figure 4 and Figure 5 As shown, the reverse osmosis membrane element 20 includes a housing 20a, a central tube 20b disposed in the housing 20a, and a reverse osmosis membrane 20c located between the central tube 20b and the housing 20a. The cleaning agent transported by the second pipeline 41 enters from the first end 200, flows through the reverse osmosis membrane 20c for cleaning, and the cleaned liquid is discharged from the second end 201.
[0045] By placing the reverse osmosis membrane element 20 to be cleaned vertically, the cleaning agent is introduced upward from the bottom and then discharged from the top, so that the reverse osmosis membrane element 20 can be cleaned more fully and the cleaning effect is better.
[0046] In some embodiments, reference Figure 2 and Figure 3The reverse osmosis membrane cleaning device further includes a filter 5. The filter 5 and the reverse osmosis membrane element 20 are both arranged on the second pipeline 41, and the two are connected in series. The liquid transported by the liquid transport device 3 enters the reverse osmosis membrane element 20 after passing through the filter 5. The filter 5 can filter particles and impurities in the liquid, thereby preventing the particles from entering the reverse osmosis membrane element 20 again, which is beneficial to improving the cleaning effect and efficiency and preventing clogging and damage to the reverse osmosis membrane 20c.
[0047] like Figure 2 and Figure 3 As shown, the second pipeline 41 includes a first pipeline 410 connected between the liquid outlet 31 and the filter 5, and a second pipeline 411 connected between the filter 5 and the first end 200 of the reverse osmosis membrane element 20. Optionally, as Figure 6 As shown, a pressure sensor 72 for detecting liquid pressure is provided in the filter 5 and / or the second pipe 411 .
[0048] In some embodiments, Figure 2 , Figure 7 and Figure 8 As shown, the second pipeline 41 includes at least one connection mechanism 43 for accessing the reverse osmosis membrane element 20. The connection mechanism 43 includes a first connection cover 431 for detachably connecting to the first end 200 of the reverse osmosis membrane element 20 and a second connection cover 432 for detachably connecting to the second end 201 of the reverse osmosis membrane element 20. The first connection cover 431 and the second connection cover 432 are sleeved on the end of the reverse osmosis membrane element 20. The first connection cover 431 is communicated with the second pipeline 411 of the second pipeline 41 to deliver the liquid transported from the second pipeline 411 into the reverse osmosis membrane element 20. The second connection cover 432 is communicated with the medicine container 1 to discharge the liquid discharged from the reverse osmosis membrane element 20 into the medicine container 1.
[0049] like Figure 2 , Fig. 9 and Fig.10As shown, the first connection cover 431 and the second connection cover 432 both include a cavity 4310, the cavity 4310 of the first connection cover 431 is connected to the second pipeline 41, and the second pipeline 41 includes a third pipeline 412 connected to the cavity 4310 of the second connection cover 432, and the third pipeline 412 is used to discharge the liquid coming out of the reverse osmosis membrane element 20 into the reagent container 1, so that the cleaning agent is continuously circulated in the pipeline system, and the cleaning agent can be fully utilized. Preferably, the internal space 43100 of the cavity 4310 is at least partially arranged relative to the area between the central tube 20b and the shell 20a, so as to enter the reverse osmosis membrane element 20 from the area between the central tube 20b and the shell 20a. The cavity 4310 is at least partially connected to the area between the shell 20a and the central tube 20b of the reverse osmosis membrane element 20, and the cleaning agent enters the cavity 4310 of the first connection cover 431 through the second pipe 411, flows into the first end 200 through the cavity 4310, and the cleaning agent flushes the reverse osmosis membrane 20c and flows out from the second end 201 into the cavity 4310 of the second connection cover 432, and finally is discharged from the cavity 4310. Optionally, the cavity 4310 is arranged relative to the area between the shell 20a and the central tube 20b, so that the area between the shell 20a and the central tube 20b is exposed in the cavity 4310, thereby facilitating the cleaning agent to flow into and out of the reverse osmosis membrane element 20.
[0050] The number of the connecting mechanism 43 can be one or more. When the number of the connecting mechanism 43 is more than one, multiple reverse osmosis membrane elements 20 can be connected. The multiple reverse osmosis membrane elements 20 are connected in parallel. The first end 200 of each reverse osmosis membrane element 20 is connected to the second pipe 411, rather than being connected end to end. In this way, the cleaning agent can directly enter each reverse osmosis membrane element 20 for cleaning, and the cleaning effect and efficiency are higher. Each reverse osmosis membrane element 20 is correspondingly provided with a branch pipe 4110 and a third pipe 412, and each of the branch pipes 4110 is provided with at least one valve 4111. Figure 8 In the embodiment, the second pipeline 41 can fix six reverse osmosis membrane elements 20 , and a branch pipeline 4110 is correspondingly arranged at the bottom of each reverse osmosis membrane element 20 , and a third pipeline 412 is correspondingly arranged at the top.
[0051] When there is no reverse osmosis membrane element 20 at a position where a reverse osmosis membrane element 20 is connected, the valve 4111 can be closed to ensure that the reverse osmosis membrane cleaning equipment can still work normally. For example, when there are only five reverse osmosis membrane elements 20 that need to be cleaned, one valve 4111 among the six valves can be closed to achieve the cleaning of the five reverse osmosis membrane elements 20.
[0052] In some embodiments, the first connection cover 431 and the second connection cover 432 are sealed and connected to the outer wall of the reverse osmosis membrane element 20 to prevent water leakage. Fig. 9 and Fig.10 As shown, a sealing ring 4312 is provided between the first connection cover 431 and the outer wall of the reverse osmosis membrane 20 and between the second connection cover 432 and the outer wall of the reverse osmosis membrane element 20 , and sealing is achieved by matching the sealing ring 4312 with the reverse osmosis membrane element 20 .
[0053] In some embodiments, the first connection cover 431 and the second connection cover 432 each include an outer ring portion 4311 for enclosing the outer periphery of the reverse osmosis membrane element 20. The outer ring portion 4311 can realize the horizontal positioning of the reverse osmosis membrane element 20, and is sealed and connected to the outer wall of the reverse osmosis membrane element 20. Fig. 9 and Fig.10 The sealing ring 4312 is provided with a convex ring 4314 located outside the outer ring portion 4311, and the convex ring 4314 is arranged opposite to the end face 4315 of the outer ring portion 4311. When the reverse osmosis membrane element 20 is connected to the connection cover, the convex ring 4314 will deform outward when it contacts the reverse osmosis membrane 20, so that the reverse osmosis membrane element 20 can be reliably connected to the connection cover and sealed, and the convex ring 4314 can improve the sealing effect. Optionally, the convex ring 4314 fits the end face 4315 of the outer ring portion 4311.
[0054] In some embodiments, Fig. 9 and Fig.10 As shown, the first connection cover 431 and the second connection cover 432 both include a support plate 4313, the support plate 4313 is connected to the outer ring portion 4311, and the cavity 4310 and the outer ring portion 4311 are respectively located on both sides of the support plate 4313. The support plate 4313 is used to abut against the end of the reverse osmosis membrane element 20 to limit the reverse osmosis membrane element 20. Specifically, the support plate 4313 of the first connection cover 431 abuts against the first end 200 of the reverse osmosis membrane element 20 to support the reverse osmosis membrane element 20. The reverse osmosis membrane element 20 is vertically arranged. The reverse osmosis membrane element 20 can be placed in the first connection cover 431 to achieve positioning, and then the second connection cover 432 can be installed. The support plate 4313 of the second connection cover 432 abuts against the second end 201 of the reverse osmosis membrane element 20 to clamp the reverse osmosis membrane element 20.
[0055] like Fig.11 As shown, the space enclosed by the outer ring portion 4311 forms an insertion port 43110 for inserting the reverse osmosis membrane element 20, the insertion port 43110 of the first connecting cover 431 is set upward, and the insertion port 43110 of the second connecting cover 432 is set downward, so that the reverse osmosis membrane element 20 can be set vertically and is easy to install.
[0056] The third pipe 412 is configured to be able to observe the liquid entering the reagent container 1 from the outside, and the cleaning condition of the reverse osmosis membrane element 20 can be judged by observing the color and other conditions of the liquid discharged from the third pipe 412. In the early stage of cleaning, the liquid discharged from the third pipe 412 is usually turbid or even black. As the cleaning work proceeds, the liquid discharged from the third pipe 412 gradually becomes clean and transparent. According to the condition of the liquid discharged from the third pipe 412, the contamination condition of the reverse osmosis membrane element 20 and the progress of cleaning can be judged. In addition, according to the color and turbidity of the liquid, it can be judged whether it is necessary to replace different types of cleaning agents to perform targeted cleaning corresponding to different pollutants.
[0057] For example, Figure 2 and Figure 7 As shown, the upper end of the medicine container 1 is provided with an opening 10, and the outlet of the third pipe 412 is located above the liquid level of the cleaning agent in the medicine container 1. When the liquid is discharged from the third pipe 412 into the medicine container 1, the liquid between the outlet of the third pipe 412 and the liquid level 1a can be observed. Optionally, the outlet of the third pipe 412 is located above the opening 10 of the medicine container 1, and there is a sufficient distance between the liquid discharged from the third pipe 412 and the liquid level 1a, so that the discharged liquid can be conveniently observed. It can be understood that the cleaning agent in the medicine container 1 can also be seen from the opening 10, so as to judge whether it is necessary to replace the new cleaning agent according to the state of the cleaning agent, so as to ensure the progress of the cleaning work. Of course, the medicine container 1 can also be set to be transparent or partially transparent, so as to observe the cleaning agent inside. In other embodiments, the third pipe 412 can also be partially or completely made of transparent material, and the liquid situation in the third pipe 412 can be observed through the transparent part.
[0058] When the reverse osmosis membrane element 20 is cleaned, the end of the central tube 20b of the reverse osmosis membrane element 20 at the first end 200 is blocked, so that more cleaning agents can pass through the gaps of the reverse osmosis membrane sheets to form parallel shear water flows, effectively improving the cleaning effect.
[0059] Further, such as Fig. 9 and Fig.10 As shown, the reverse osmosis membrane cleaning device includes a plug 203 that seals the central tube 20b at one side of the first end 200. Optionally, the plug 203 is at least partially inserted into the central tube 20b.
[0060] The second end 201 is the water inlet end of the reverse osmosis membrane element 20 when performing filtering work. When performing filtering work, the reverse osmosis membrane element 20 is usually connected in series in a pipeline system to work. Since the concentrated water produced by the reverse osmosis membrane element 20 flows backward, the pollution is usually more serious as it flows backward. This makes the pollution degree of the water outlet end of the reverse osmosis membrane element 20 when performing filtering work usually more serious than that of its water inlet end. The water outlet end of the reverse osmosis membrane element 20 when performing filtering work is set as the first end 200 of the reverse osmosis membrane element 20 (i.e., the water inlet end during cleaning), so that the cleaning agent can first contact with the more seriously polluted parts of the reverse osmosis membrane element 20, give full play to the cleaning effect of the cleaning agent, and perform the cleaning work more efficiently.
[0061] In some embodiments, the connection cover and the reverse osmosis membrane element 20 are fixedly connected, for example, by means of snaps, threads, or bolts, to ensure the reliability of the connection between the connection cover and the reverse osmosis membrane element 20 during the cleaning process. Figure 3 and Figure 7 As shown, the reverse osmosis membrane cleaning device also includes a clamping mechanism 6, through which the connection cover is kept pressed on the reverse osmosis membrane element 20. The clamping mechanism 6 includes a fixed frame 60, a movable frame 61 connected to the second connection cover 432, and a linear drive device 62 connected between the fixed frame 60 and the movable frame 61, and the first connection cover 431 is connected to the fixed frame 60 to achieve relative fixation. The first connection cover 431 and the second connection cover 432 are slidably matched with the reverse osmosis membrane element 20, and can move relative to the reverse osmosis membrane element 20 along the axial direction of the reverse osmosis membrane element 20. The linear drive device 62 is used to drive the movable frame 61 to move along the vertical direction, so that the second connection cover 432 is sleeved on the reverse osmosis membrane element 20 to achieve the compression and fixation of the reverse osmosis membrane element 20. It can be understood that when the second connection cover 432 rises to be separated from the reverse osmosis membrane element 20, the reverse osmosis membrane element 20 can be taken out.
[0062] The linear drive device 62 may be, for example, a pneumatic cylinder, an electric cylinder, a hydraulic cylinder, or the like, or may be a device that realizes a linear drive function by cooperating with a motor and a transmission structure (such as a belt drive, a chain drive, a connecting rod drive, etc.). Figure 7In the figure, the linear drive device 62 is a hydraulic cylinder, whose body 620 is fixedly connected to the fixed frame 60, and the drive shaft 621 is connected to the movable frame 61, and the movable frame 61 and the second connection cover 432 are driven to move by telescopic movement. When the reverse osmosis membrane element 20 is vertically arranged, the linear drive device 62 drives the second connection cover 432 to do lifting movement, that is, to move along the vertical direction. Optionally, the movable frame 61 is connected to the second connection cover 432 of more than two groups of connection mechanisms 42 at the same time, and multiple reverse osmosis membrane elements 20 can be connected through one movable frame 61. In the illustrated embodiment, the movable frame 61 is connected to the second connection covers 432 of all the connection mechanisms 42. In other embodiments, the movable frame 61 can be connected to only one second connection cover 432.
[0063] The reverse osmosis membrane cleaning equipment includes a control box 71, in which a controller 710 is provided. Optionally, a linear drive device 62 is electrically connected to the controller 710. When the pressure sensor 72 detects that the pressure in the pipeline increases, the controller 710 controls the linear drive device 62 to increase the driving force for pressing the second connecting cover 432 to achieve a reliable sealing connection and prevent leakage. Conversely, when the pressure in the pipeline decreases, the driving force for pressing the second connecting cover 432 can be reduced.
[0064] In some embodiments, at least two groups of connection mechanisms 43 are correspondingly arranged on both sides of the medicine container 1, and at least two groups of connection mechanisms 43 are arranged along the extension direction of the corresponding side of the medicine container 1. Dividing a plurality of connection mechanisms 43 into two groups and arranging them on both sides of the medicine container 1 can reasonably utilize space, increase the number of reverse osmosis membrane elements 20 that can be cleaned at the same time, and thus improve the working efficiency of the reverse osmosis membrane cleaning equipment. Figure 7 In the illustrated embodiment, the medicine container 1 is rectangular, and at least two groups of connecting mechanisms 43 are provided at both ends of the width direction Y. In the illustrated embodiment, the number of connecting mechanisms 43 is specifically six groups, which are symmetrically arranged on both sides of the medicine container 1, and can simultaneously fix six reverse osmosis membrane elements 20 for cleaning.
[0065] In some embodiments, Figure 7 As shown, at least one linear drive device 62 is provided at both ends of the medicine container 1 in the length direction X, thereby improving the fixing effect; the movable frame 61 is located directly above the medicine container 1 and is connected to all the linear drives 62, which can improve the stability of the movable frame 61.
[0066] The above are only specific implementations of the present invention, and any improvements made based on the concept of the present invention are considered to be within the protection scope of the present invention.
