Description

Technical Field

[0001] This utility model relates to a lightweight and efficient flat-sheet membrane module structure, belonging to the field of flat-sheet reverse osmosis technology. Background Technology

[0002] Currently, traditional flat-sheet membrane modules tend to be designed with complexity in mind in pursuit of higher stability and filtration efficiency. However, this design approach directly leads to a complex internal structure with numerous components, each requiring precise machining and assembly. This not only increases the difficulty of manufacturing but also raises the requirements for production equipment and technology. Furthermore, the large number of components also means higher material costs and inventory management costs.

[0003] Due to their complex structure and numerous components, the installation of traditional flat-sheet membrane modules is quite cumbersome. Installers must assemble each component one by one according to strict steps and sequences, ensuring that each connection point meets the specified tightening force and sealing requirements. This not only demands high levels of professional skills and experience from the installers but also increases the error rate and time cost during the installation process. Furthermore, the cumbersome installation process limits the on-site installation and rapid replacement capabilities of membrane modules.

[0004] Furthermore, traditional flat-sheet membrane modules require two different end plates, leading to increased production management difficulties, higher costs, and limitations in versatility and interchangeability, resulting in longer production cycles and inventory backlogs. Due to the limited internal space of the modules and the need to allow sufficient channels for water flow and membrane vibration cleaning, it is difficult to significantly increase the influent flow rate and membrane area. This makes traditional flat-sheet membrane modules inadequate for treating large volumes of water or high-concentration wastewater, resulting in low treatment efficiency and high energy consumption. Simultaneously, the smaller membrane area also means a limited amount of wastewater can be treated per unit time, restricting the overall treatment capacity and efficiency of the water treatment system.

Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0027] See Figure 1 , Figure 2 and Figure 3 This utility model provides a lightweight and efficient flat sheet membrane module structure, including a first end plate 1, a second end plate 2, a flow guide plate 3, a lip ring 4, and a center rod 5;

[0028] Among them, a number of guide disks 3 are sequentially assembled to form a guide system 6. One end of the guide system 6 is fixedly connected to the first end plate 1, and the other end of the guide system 6 is fixedly connected to the second end plate 2. A diaphragm 7 is sandwiched between two adjacent guide disks 3. An end plate sealing groove 8 is formed on the edge of the first end plate 1, and a lip ring 4 is set on the periphery of the first end plate 1.

[0029] The central rod 5 passes through the centerline of the first end plate 1, the flow guiding system 6, and the second end plate 2. One end of the central rod 5 is exposed on the outside of the first end plate 1, and the other end of the central rod 5 is exposed on the outside of the second end plate 2.

[0030] In this embodiment, annular reinforcing ribs 9 and radial reinforcing ribs 10 are distributed on the inner sides of the first end plate 1 and the second end plate 2; the annular reinforcing ribs 9 and the radial reinforcing ribs 10 intersect each other.

[0031] Specifically, the design of the annular reinforcing rib 9 and the radial reinforcing rib 10 enables the first end plate 1 and the second end plate 2 to achieve a lightweight design while ensuring the strength of the first end plate 1 and the second end plate 2. Both the first end plate 1 and the second end plate 2 are provided with an upper connection port and a lower connection port, which can be connected to the upper end and the lower end of the guide plate 3, respectively, to facilitate the assembly of the membrane module.

[0032] The first end plate 1 and the second end plate 2 have the same structural design, which enhances the versatility and interchangeability of the first end plate 1 and the second end plate 2, and facilitates production and maintenance.

[0033] In this embodiment, the first end plate 1 with the lip ring 4 serves as the inlet of the flat membrane module structure; the first end plate 1 is distributed with flow channels; the outer wall of the central rod 5 is distributed with a number of water outlets 11, and the water filtered by the membrane 7 is collected in the interior of the central rod 5 through the water outlets 11; a water outlet 12 is formed at one end of the central rod 5 near the second end plate 2.

[0034] Specifically, the first end plate 1 with the lip ring 4 serves as the inlet. Water flows into the channel in the middle of the first end plate 1 guided by the lip ring 4, and then is evenly distributed to the guide plate 3. Under the guidance of the guide plate 3, the water flows over the surface of the membrane 7 for filtration. The microporous structure on the membrane 7 traps impurities and particulate matter, and the purified permeate enters the central rod 5 through the permeate outlet 11 on the other side of the membrane 7. The permeate collects inside the central rod 5 and then flows out of the membrane module. The concentrate containing impurities flows out from the second end plate 2 for further treatment or discharge.

[0035] In this embodiment, a first groove 13 is formed at one end of the central rod 5, a first sealing groove 14 is provided on one side of the first groove 13, and a second sealing groove 15 is provided on the other side of the first groove 13; a second groove 16 is formed at the other end of the central rod 5, a third sealing groove 17 is provided on one side of the second groove 16, and a fourth sealing groove 18 is provided on the other side of the second groove 16.

[0036] Specifically, the first slot 13 and the second slot 16 are used to install elastic retaining rings to secure the entire flat sheet membrane module. The first sealing slot 14 and the third sealing slot 17 are used to install seals between membrane modules, the second sealing slot 15 is used to install seals between the first end plate 1 and the center rod 5, and the fourth sealing slot 18 is used to install seals between the second end plate 2 and the center rod 5, thus achieving a sealing effect between the inlet water and the product water.

[0037] The design of the center rod 5 is simple and clear, reducing unnecessary complexity and making its functional divisions clearer, easier to understand and operate. Due to its relatively simple structure, the machining process of the center rod 5 is also relatively convenient. Using modern machining equipment and technology, the dimensions and shapes of each component can be precisely machined, ensuring the accuracy and quality of the center rod 5. At the same time, the simple structure reduces machining costs and improves production efficiency. The design of the first retaining groove 13 and the second retaining groove 16 at both ends of the center rod 5 makes the installation of the elastic retaining ring very simple. Operators only need to fit the elastic retaining ring into the correct groove to secure the membrane module, without the need for additional fasteners or tools. This design not only improves installation efficiency but also reduces installation difficulty and cost. The cooperation of the first sealing groove 14 and the second sealing groove 15, and the cooperation of the third sealing groove 17 and the fourth sealing groove 18, achieves a double sealing design, ensuring effective isolation between the inlet water and the product water, preventing cross-contamination and leakage. Meanwhile, the use of high-quality sealing components further enhances the sealing performance, ensuring the stable operation of the membrane module.

[0038] The center rod 5, as a modular component of the membrane module, can be flexibly combined with other components such as the guide plate 3 and end plates to form membrane module units of different specifications and functions. This modular design not only improves the maintainability and scalability of the system but also reduces production costs and inventory pressure. When it is necessary to replace or repair the membrane module, the center rod 5 and other components can be easily removed by simply disassembling the elastic retaining ring, the first end plate 1, and the second end plate 2. This design makes maintenance simple and quick, reducing maintenance costs and downtime.

[0039] In one possible embodiment, an outer membrane housing is also included, with the lightweight, high-efficiency flat-panel membrane module structure placed flat within the outer membrane housing. Membrane modules can also be connected to each other using existing connectors.

[0040] During the assembly process of this utility model, the membrane 7 is precisely clamped between the two guide plates 3 to ensure that the membrane 7 is flat and stable, providing a foundation for the subsequent filtration process. Then, the first end plate 1 and the second end plate 2 are mechanically connected to the guide plates 3 through their upper and lower connection ports, respectively. Elastic retaining rings are used to secure the first end plate 1 and the second end plate 2 around their peripheries to ensure the overall stability of the membrane module. Simultaneously, high-quality sealing rings are placed in the end plate sealing grooves 8 to achieve a tight seal between the membrane modules and prevent leakage. Finally, the above steps are repeated to assemble multiple membrane module units according to the design requirements. Each membrane module unit can work independently or be flexibly combined within the membrane housing using connectors to adapt to different scales of water treatment needs. The lightweight end plate design reduces the overall weight, while the modular design makes the assembly, disassembly, and replacement of the membrane modules simpler and faster. The first end plate 1 also adopts a universal design concept, meaning its structure can adapt to the upper and lower end faces of the guide plates 3. This design reduces the number of parts, lowers the difficulty and cost of inventory management, and also facilitates user maintenance and replacement.

[0041] In summary, this utility model comprises a first end plate 1, a second end plate 2, a guide plate 3, a lip ring 4, and a central rod 5; a plurality of guide plates 3 are sequentially assembled to form a guide system 6, one end of the guide system 6 is fixedly connected to the first end plate 1, and the other end of the guide system 6 is fixedly connected to the second end plate 2; a diaphragm 7 is sandwiched between two adjacent guide plates 3; an end plate sealing groove 8 is formed on the edge of the first end plate 1, and the lip ring 4 is disposed on the periphery of the first end plate 1; the central rod 5 passes through the centerline of the first end plate 1, the guide system 6, and the second end plate 2, one end of the central rod 5 is exposed on the outside of the first end plate 1, and the other end of the central rod 5 is exposed on the outside of the second end plate 2. The design of the annular reinforcing rib 9 and the radial reinforcing rib 10 enables the first end plate 1 and the second end plate 2 to achieve a lightweight design while ensuring their strength. Both the first end plate 1 and the second end plate 2 are equipped with upper and lower connection ports, which can be connected to the upper and lower ends of the guide plate 3, respectively, facilitating membrane module assembly. The structural design of the center rod 5 is simple and clear, reducing unnecessary structural complexity and making the functional division of the center rod 5 clearer, easier to understand and operate. Due to the relatively simple structure of the center rod 5, its processing is also relatively convenient. By using modern machining equipment and technology, the dimensions and shapes of each component can be precisely machined, ensuring the accuracy and quality of the center rod 5. At the same time, the simple structure also reduces processing costs and improves production efficiency. The design of the first slot 13 and the second slot 16 at both ends of the center rod 5 makes the installation of the elastic retaining ring very simple. Operators can simply insert the elastic retaining ring into the corresponding slot to secure the membrane module, eliminating the need for additional fasteners or tools. This design not only improves installation efficiency but also reduces installation difficulty and cost. The cooperation of the first sealing groove 14 and the second sealing groove 15, and the cooperation of the third sealing groove 17 and the fourth sealing groove 18, achieves a double sealing design, ensuring effective isolation between the influent and the product water, preventing cross-contamination and leakage. Simultaneously, the use of high-quality seals further enhances sealing performance, ensuring stable operation of the membrane module.
