Description

Technical Field

[0001] This utility model relates to the field of RO membrane filter technology, specifically to an RO membrane filter that can improve the water production rate of RO membranes. Background Technology

[0002] RO membrane, or reverse osmosis membrane, is the core filtration component of a water purifier. It uses pressure to force water molecules to permeate against the concentration gradient, allowing only water molecules and a small amount of mineral ions to pass through while intercepting harmful substances such as bacteria, viruses, heavy metals, and pesticides. RO membrane filter cartridges are required for high-precision filtration of water sources. To improve filtration efficiency, the water production rate of the RO membrane needs to be increased.

[0003] In existing technologies, RO membrane filter cartridges are typically composed of a sealing cap, a product water pipe, and a filter assembly. The sealing cap, product water pipe, and filter assembly are usually fixedly installed together to form the RO membrane filter cartridge. The filter assembly is made by winding and wrapping multiple layers of filter membranes together.

[0004] However, there are some drawbacks: it is not easy to create isolation between the multiple filter membranes to improve the efficiency of water flow and infiltration; it is not easy to isolate and support the filter assembly and the product water pipe, causing the filter assembly and the product water pipe to fit together. As a result, most of the filtered water needs to permeate through the filter assembly to the inlet and be introduced into the product water pipe, resulting in low efficiency of water flow between the multiple filter membranes and thus low water production rate of the RO membrane. At the same time, the filter assembly is composed of multiple filter membranes and has a relatively soft structure, which is easily damaged by scratches or collisions. Traditional RO membrane filter cartridges are not convenient to disassemble and replace the filter assembly separately. After the filter assembly has been used for a long time or is damaged, the entire RO membrane filter cartridge needs to be replaced, increasing the cost of use. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an RO membrane filter element that can improve the water production rate of RO membrane, which can effectively solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: This utility model provides an RO membrane filter element that can improve the water production rate of RO membrane, including a support assembly, a water production assembly fixedly installed on one side of the support assembly, the water production assembly including a water production pipe, a filter assembly surrounding the water production pipe, one end of the filter assembly extending into the inside of the support assembly, and a disassembly assembly provided at the other end of the filter assembly. The assembly includes a movable cover that is fitted around the water production pipe. The other end of the filter assembly extends to the inside of the movable cover. A movable sleeve is rotatably connected to one side of the movable cover, and the movable sleeve is threadedly connected to the water production pipe.

[0007] Furthermore, the support assembly includes a sealing cover, a fixing plate is fixedly installed on the inner side of the sealing cover, the water production pipe is fixedly connected to one side of the fixing plate, multiple water inlet holes are opened on the inner side of the fixing plate surrounding the water production pipe, each of the multiple water inlet holes corresponds to a filter assembly, one end of the filter assembly is attached to the fixing plate, and a water injection pipe is fixedly connected to one side of the sealing cover.

[0008] Furthermore, a first mesh sleeve is fitted around the water production pipe. The first mesh sleeve is located inside the filter assembly and supports the filter assembly and the water production pipe. Multiple water inlet holes are provided at the top and bottom of the water production pipe. All of the multiple water inlet holes are located inside the filter assembly. A threaded sleeve is fixedly connected to the periphery of the water production pipe on one side of the water inlet hole. The movable sleeve is located outside the threaded sleeve and is threadedly connected to the threaded sleeve.

[0009] Furthermore, the filter assembly includes a first filter layer, and a second mesh sleeve, a second filter layer, a third mesh sleeve, a third filter layer, a fourth mesh sleeve, a fourth filter layer, a fifth mesh sleeve, a fixing sleeve, and an outer layer of adhesive tape are sequentially wound and fixed around the periphery of the first filter layer. The first mesh sleeve, the second mesh sleeve, the third mesh sleeve, the fourth mesh sleeve, and the fifth mesh sleeve are all made of multiple crossbars and circular hoops, and each of the multiple circular hoops is located on the periphery of the multiple crossbars.

[0010] Furthermore, a support frame is fixedly installed on one side of the movable cover, the movable sleeve is located on the periphery of the support frame and is rotatably connected to the support frame, and a sealing ring corresponding to the movable sleeve is fixedly connected to one end of the support frame.

[0011] Furthermore, a sewage pipe is fixedly installed on one side of the movable cover below the movable sleeve, and both the movable sleeve and the sewage pipe are connected to the movable cover.

[0012] Furthermore, a fixing frame is fixedly installed on the inner side of the movable cover. The fixing frame is located around the water production pipe. The other end of the filter assembly extends to the inner side of the movable cover and fits against the fixing frame. Multiple drain troughs are opened on the inner side of the fixing frame, and each of the multiple drain troughs corresponds to the filter assembly.

[0013] The technical solution provided by this utility model has the following advantages compared with the known prior art: 1. This utility model uses a filter assembly. During use, water is injected into the filter assembly, allowing the water to permeate and filter inwards. The filtered water is then introduced into the water production assembly through the inlet and discharged to the left. The fifth, fourth, third, and second mesh sleeves isolate the different filter layers inside the filter assembly, facilitating the flow of water between them and improving filtration efficiency. The first mesh sleeve provides isolation and support between the filter assembly and the water production assembly, allowing the filtered water to flow through the periphery of the water production assembly. This facilitates the rapid introduction of filtered water into the water production pipe through the inlet and discharge to the left, increasing the water production rate during use.

[0014] 2. By rotating the movable sleeve and utilizing the threaded connection between the disassembly / assembly component and the threaded sleeve, the movable sleeve can move left and right along the threaded sleeve, simultaneously moving the movable cover left and right. By moving the movable cover to the left, it separates from the water production pipe, making it easy to move the filter component to the left and remove it. Then, another filter component is placed around the water production pipe, so that one end of the filter component extends to the inside of the sealing cover. Finally, the movable cover is placed around the water production pipe, and the movable sleeve is screwed around the threaded sleeve. This allows for convenient disassembly and replacement of the filter component, making maintenance simpler and faster, and reducing operating costs. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0019] The present invention will be further described below with reference to the embodiments.

[0020] Example 1: Refer to Figures 1 to 5 This is the first embodiment of the present invention, which discloses an RO membrane filter element that can improve the water production rate of RO membrane. It includes a support component 1, a water production component 2 fixedly installed on one side of the support component 1, the water production component 2 includes a water production pipe 21, a filter component 3 is sleeved around the water production pipe 21, one end of the filter component 3 extends into the inside of the support component 1, and the other end of the filter component 3 is provided with a disassembly and assembly component 4. In the process of use, water is injected into the support component 1, and then the water is allowed to pass through the inside of the filter component 3 and permeate and filter inward. Finally, the permeated and filtered clean water is introduced into the water production component 2 and discharged to the left. Therefore, the water source can be filtered with precision. The disassembly assembly 4 includes a movable cover 41, which is fitted around the water production pipe 21. The other end of the filter assembly 3 extends to the inside of the movable cover 41. A movable sleeve 44 is rotatably connected to one side of the movable cover 41. The movable sleeve 44 is threadedly connected to the water production pipe 21. By rotating the movable sleeve 44, the movable cover 41 can be moved to the left, which can separate the movable cover 41 from the water production pipe 21, making it easy to disassemble and remove the movable cover 41. Then, the filter assembly 3 can be disassembled and removed from the outside of the water production pipe 21, which can facilitate the disassembly, assembly, and replacement of the filter assembly 3.

[0021] The support assembly 1 includes a sealing cover 11, a fixing plate 13 is fixedly installed on the inner side of the sealing cover 11, a water production pipe 21 is fixedly connected to one side of the fixing plate 13, and multiple water inlet holes 14 are opened on the inner side of the fixing plate 13 around the water production pipe 21. The multiple water inlet holes 14 correspond to the filter assembly 3. One end of the filter assembly 3 is attached to the fixing plate 13. A water injection pipe 12 is fixedly connected to one side of the sealing cover 11. Water is injected into the interior of the sealing cover 11 through the water injection pipe 12. The fixing plate 13 blocks the water inside the sealing cover 11, allowing the water to permeate to the other side of the fixing plate 13 through the multiple water inlet holes 14. This allows the water to flow into the interior of the filter assembly 3 and be filtered by permeating inward from the interior of the filter assembly 3. A first mesh sleeve 23 is fitted around the water production pipe 21. The first mesh sleeve 23 is located inside the filter assembly 3 and supports the filter assembly 3 and the water production pipe 21. Multiple water inlet holes 22 are provided at the top and bottom of the water production pipe 21, all located inside the filter assembly 3. A threaded sleeve 24 is fixedly connected to the periphery of the water production pipe 21 on one side of the water inlet hole 22. A movable sleeve 44 is located outside the threaded sleeve 24 and is threadedly connected to it. The filtered water from the filter assembly 3 can be introduced into the water production pipe 21 through the water inlet hole 22, and then the water flows to the left through the water production pipe 21 and is discharged. The first mesh sleeve 23 supports and isolates the water production pipe 21 from the filter assembly 3, preventing the inner side of the filter assembly 3 from adhering to the periphery of the water production pipe 21 and affecting the flow of filtered water. The filtered water flows through the periphery of the water production pipe 21, which facilitates the introduction of water into the water production pipe 21 for discharge, thereby improving the water production rate of the water production pipe 21. The threaded connection between the threaded sleeve 24 and the movable sleeve 44 allows the movable sleeve 44 to move left and right when rotating in different directions. The filter assembly 3 includes a first filter layer 31. The periphery of the first filter layer 31 is sequentially wrapped and fixed with a second mesh sleeve 32, a second filter layer 33, a third mesh sleeve 34, a third filter layer 35, a fourth mesh sleeve 36, a fourth filter layer 37, a fifth mesh sleeve 38, a fixed sleeve 39, and an outer layer of adhesive tape 310. The first mesh sleeve 23, the second mesh sleeve 32, the third mesh sleeve 34, the fourth mesh sleeve 36, and the fifth mesh sleeve 38 are all made of multiple crossbars 25 and circular hoops 26. Each of the multiple circular hoops 26 is located on the periphery of the multiple crossbars 25.

[0022] In this embodiment, when the water source inside the sealing cap 11 flows into the filter assembly 3, it flows into the cavity formed by the support of the fifth mesh sleeve 38 and the fourth mesh sleeve 36. Then, the water source flows to the left along the fifth mesh sleeve 38 and the fourth mesh sleeve 36. During the flow, the water source simultaneously passes through the fourth filter layer 37, the third filter layer 35, the second filter layer 33, and the first filter layer 31 in sequence to penetrate and filter inward. The fifth mesh sleeve 38, the fourth mesh sleeve 36, the third mesh sleeve 34, the second mesh sleeve 32, and the first mesh sleeve 23 sequentially support the fixed sleeve 39, the fourth filter layer 37, the third filter layer 35, the second filter layer 33, the first filter layer 31, and the water production pipe 21. The isolation allows water to flow through the gaps between the fixed sleeve 39, the fourth filter layer 37, the third filter layer 35, the second filter layer 33, the first filter layer 31, and the water production pipe 21, improving the efficiency of water infiltration and increasing the water production rate. Among them, the fourth filter layer 37 is made of PP cotton filter element, which can intercept suspended solids and sediment in the water source; the third filter layer 35 is made of granular activated carbon, which can adsorb residual chlorine and organic matter; the second filter layer 33 is made of polyvinylidene fluoride, which can perform primary filtration of the water source; and the first filter layer 31 is made of RO reverse osmosis membrane, which can deeply filter bacteria, viruses, and heavy metals, and can perform precision filtration of the water source.

[0023] Example 2: Refer to Figures 2 to 6 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: a support frame 46 is fixedly installed on one side of the movable cover 41, the movable sleeve 44 is located on the periphery of the support frame 46 and is rotatably connected to the support frame 46, a sealing ring 47 corresponding to the movable sleeve 44 is fixedly connected to one end of the support frame 46, a sewage pipe 42 is fixedly installed on one side of the movable cover 41 below the movable sleeve 44, the movable sleeve 44 and the sewage pipe 42 are both connected to the movable cover 41, a fixing frame 43 is fixedly installed on the inner side of the movable cover 41, the fixing frame 43 is located on the periphery of the water production pipe 21, the other end of the filter assembly 3 extends to the inner side of the movable cover 41 and fits against the fixing frame 43, and multiple sewage discharge troughs 45 are opened on the inner side of the fixing frame 43, and the multiple sewage discharge troughs 45 are all corresponding to the filter assembly 3.

[0024] In this embodiment, during use, most of the water source permeates inward through the filter assembly 3, while a small amount of water flows to the left through the gaps inside the filter assembly 3. This small amount of water can cause the impurities intercepted during filtration to move to the left and form sewage. Then, the sewage flows to the outside of the sewage pipe 42 through multiple sewage discharge troughs 45, allowing the sewage to be discharged through the sewage pipe 42. By rotating the movable sleeve 44, the movable cover 41 can be moved to the left, which can separate the sewage pipe 42 from the water production pipe 21, making it easier to disassemble and replace the filter assembly 3 and reduce the cost of use.

[0025] The workflow of this utility model is as follows: First, when in use, water is injected into the sealing cap 11 through the water injection pipe 12, so that the water is introduced into the cavity supported by the fourth mesh sleeve 36 and the fifth mesh sleeve 38. Then, the water is filtered inward through the fourth filter layer 37, the third filter layer 35, the second filter layer 33 and the first filter layer 31 in sequence. Finally, the filtered water is introduced into the water production pipe 21 through the water inlet hole 22 and discharged to the left. The fifth mesh sleeve 38, the fourth mesh sleeve 36, the third mesh sleeve 34 and the second mesh sleeve 32 isolate the different filter layers inside the filter assembly 3, which facilitates the flow of water between the different filter layers, thereby improving the filtration efficiency and increasing the water production rate. The first mesh sleeve 23 isolates and supports the filter assembly 3 and the water production assembly 2, which facilitates the flow of filtered clean water through the periphery of the water production assembly 2, and facilitates the rapid introduction of filtered water into the water production pipe 21 through the water inlet 22 and discharge to the left, thereby improving the filtration efficiency and increasing the water production rate during use. Meanwhile, the first mesh sleeve 23, the fifth mesh sleeve 38, the fourth mesh sleeve 36, the third mesh sleeve 34 and the second mesh sleeve 32 are all composed of multiple crossbars 25 and circular hoops 26. The circular hoops 26 are located on the periphery of the crossbars 25. By utilizing the periphery of the circular hoops 26 to contact the outer filter layer, water can flow through the gaps between the inner crossbars 25, allowing the water to fully flow and contact the periphery of the filter layer, which facilitates the flushing and removal of impurities intercepted on the periphery of the filter layer. By rotating the movable sleeve 44 and utilizing the threaded connection between the movable sleeve 44 and the threaded sleeve 24, the movable sleeve 44 can move the movable cover 41 to the left to separate it from the water production pipe 21. This makes it easy to move the filter assembly 3 to the left and remove it. Then, another filter assembly 3 is placed around the water production pipe 21, so that one end of the filter assembly 3 extends to the inside of the sealing cover 11. Finally, the movable cover 41 is placed around the water production pipe 21, and the movable sleeve 44 is screwed around the threaded sleeve 24. This allows for easy disassembly and replacement of the filter assembly 3, making maintenance simpler and faster, and reducing operating costs.

[0026] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
