Description

Technical Field

[0001] This utility model relates to the field of MBR membrane structure components technology, and in particular to an MBR membrane structure that is easy to clean and replace. Background Technology

[0002] Existing MBR membrane structure modules are generally used for wastewater treatment. Therefore, after a long period of adaptation, pollutants will be adsorbed on the surface of the MBR membrane structure, requiring cleaning or replacement of the MBR membrane structure module. However, existing MBR membrane structure modules are generally fixed with a large number of bolts and plugs. When disassembling or installing the MBR membrane structure module, because the MBR cleaning cycle is relatively long and the working environment of the MBR membrane structure is relatively harsh, it is difficult to disassemble the bolts or plugs. After cleaning, all bolts need to be fixed again during installation. The installation and disassembly efficiency is low, and a lot of time is wasted, which is not conducive to cleaning or replacing the MBR membrane structure module.

[0003] Patent application number 202020253193.2 discloses a detachable and splicable MBR membrane structure module. This utility model facilitates the disassembly and installation of the membrane fiber assembly. An arc-shaped fixing block and an arc-shaped positioning groove cooperate to fix the fixing rod and the membrane fiber assembly. A columnar locking block and a columnar locking groove are used to connect and install the fixing plate. Then, the first bolt is installed to complete the splicing and installation of the MBR membrane structure module. When it is necessary to disassemble the membrane fiber assembly, the first bolt of one of the fixing plates is removed, and the fixing plate is taken off. Because the arc-shaped fixing block on the fixing rod contacts the inner wall of the arc-shaped positioning groove but is not fixed, the membrane fiber assembly can be removed by pulling out the fixing rod by hand for cleaning or replacement. Although this MBR membrane structure module has largely eliminated the use of bolts, the first bolt still has the problem of corrosion and difficulty in removal during disassembly. Additionally, the use of locking grooves and blocks for connection also adds inconvenience to disassembly. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an MBR membrane structure that is easy to assemble and disassemble, and easy to clean and replace.

[0005] The technical solution adopted by this utility model to solve its technical problem is: the MBR membrane structure that is easy to clean and replace includes a plurality of MBR membrane structure curtain units disposed within a support frame and a fixing mechanism for fixing the MBR membrane structure curtain units.

[0006] The MBR membrane structure curtain unit includes a membrane frame and membrane fibers disposed on the membrane frame, with limit protrusions provided at both ends of the membrane frame;

[0007] The fixing mechanism includes a first limiting plate for fixing the limiting protrusion in the horizontal direction and a second limiting plate disposed on both sides of the first limiting plate for fixing the limiting protrusion in the vertical direction. A portion of the second limiting plate is pressed onto the first limiting plate and connected to the support frame by fasteners.

[0008] Furthermore, the first limiting plate has a first limiting hole corresponding to the limiting protrusion, and the first limiting hole is a waist hole opened in the horizontal direction.

[0009] Furthermore, the second limiting plate has a second limiting hole corresponding to the limiting protrusion, and the second limiting hole is an open insertion interface with an open end.

[0010] Furthermore, the second limiting plate and the supporting frame are provided with fixing screw holes, the fasteners include fastening bolts, and the fasteners are provided with sealing components for sealing.

[0011] Furthermore, the sealing component includes a first flange disposed at the lower part of the nut of the fastening bolt, and after the fastening bolt is tightened, the first flange presses against the outer edge of the fixing screw hole.

[0012] Furthermore, a second flange is provided on the outer edge of the fixing screw hole, and after the fastening bolt is tightened, the first flange presses against the second flange.

[0013] Furthermore, the screw hole is a countersunk hole, a first stepped limiting groove is provided on the upper part of the second flange, and a second stepped limiting groove corresponding to the first stepped limiting groove is provided on the second flange.

[0014] This easy-to-clean and replaceable MBR membrane structure employs first and second limiting plates to limit the MBR membrane structure curtain unit in both horizontal and vertical directions, thereby achieving fixation with the limiting protrusions. During disassembly, because of the fixation in two directions, the first and second limiting plates will not jam with the limiting protrusions of the membrane frame even after prolonged use, making disassembly more convenient. Furthermore, the plug-in structure further enhances installation and disassembly efficiency. Attached Figure Description

[0023] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0024] like Figure 1-5 As shown, the MBR membrane structure, which is easy to clean and replace, includes several MBR membrane structure curtain units 2 disposed within the support frame 1 and a fixing mechanism for fixing the MBR membrane structure curtain units 2.

[0025] The MBR membrane structure curtain unit 2 includes a membrane frame 21 and membrane filaments 22 disposed on the membrane frame 21. Limiting protrusions 23 are provided at both ends of the membrane frame 21.

[0026] The fixing mechanism includes a first limiting plate 3 for fixing the limiting protrusion 23 in the horizontal direction and a second limiting plate 4 for fixing the limiting protrusion 23 in the vertical direction, which is provided on both sides of the first limiting plate 3. A portion of the second limiting plate 4 is pressed on the first limiting plate 3 and connected to the support frame 1 by fasteners.

[0027] This easy-to-clean and replaceable MBR membrane structure employs first and second limiting plates 4 to limit the MBR membrane structure curtain unit 2 in both horizontal and vertical directions, thereby achieving fixation with the limiting protrusions 23. During disassembly, because of the fixation in two directions, the first and second limiting plates 3 will not jam with the limiting protrusions 23 of the membrane frame 21 even after prolonged use, making disassembly more convenient. Furthermore, the plug-in structure further enhances installation and disassembly efficiency.

[0028] The first limiting plate 3 has a first limiting hole 31 corresponding to the limiting protrusion 23. The first limiting hole 31 is a horizontally oriented slot. In this embodiment, the limiting protrusion 23 is preferably cylindrical. In this structure, the installation of the MBR membrane structure curtain unit 2 and the support frame 1 can adopt the connection structure disclosed in application number 202020253193.2, that is, the membrane frame 21 is fixed by the cooperation of the arc-shaped fixing block and the arc-shaped positioning groove, and then the first limiting plate 3 is installed. Since the first limiting hole 31 on the first limiting plate 3 is a horizontally oriented slot, the width of the slot is greater than the diameter of the limiting protrusion 23, thus limiting the position of the membrane frame 21 in the vertical direction.

[0029] The second limiting plate 4 has a second limiting hole 41 corresponding to the limiting protrusion 23. The second limiting hole 41 is an open insertion interface with an open end. The second limiting plate 4 presses on the first limiting plate 3. The second limiting hole 41 on the second limiting plate 4 is an open insertion interface. After the second limiting plate 4 is installed, the limiting protrusion 23 will be limited in a horizontal position by the second limiting hole 41. At this time, the limiting protrusion 23 is fixed.

[0030] The second limiting plate 4 and the supporting frame 1 are provided with fixing screw holes 42. The fasteners include fastening bolts 5 and sealing components for sealing are provided on the fasteners. After the second limiting plate 4 and the first limiting plate 3 are engaged, the fastening bolts 5 and the fixing screw holes 42 are engaged to achieve fixation, and the connection between the fastening bolts 5 and the fastening screw holes is protected by the sealing components.

[0031] In this embodiment, the sealing component includes a first flange 51 disposed at the lower part of the nut of the fastening bolt 5. After the fastening bolt 5 is tightened, the first flange 51 presses against the outer edge of the fixing screw hole 42.

[0032] To further improve the fit, a second flange 43 is provided on the outer edge of the fixing screw hole 42. After the fastening bolt 5 is tightened, the first flange 51 presses against the second flange 43. Preferably, the screw hole is a countersunk hole, and a first stepped limiting groove is provided on the upper part of the second flange 43. A second stepped limiting groove corresponding to the first stepped limiting groove is provided on the second flange 43.

[0033] Finally, it should be noted that in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0034] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
