Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment and reuse technology, specifically a combined MBR filtration membrane module. Background Technology

[0002] The modular MBR filtration membrane module is a core modular water treatment device that combines membrane separation units with biological treatment units. It is assembled from multiple membrane units and is mainly used in municipal sewage treatment and industrial wastewater treatment to efficiently achieve solid-liquid separation and deep purification of sewage.

[0003] The prior art patent document CN217972724U provides a combined MBR filtration membrane module, including a frame, mounting plate, water guide box, MBR membrane, water collection box, connecting conduit, combined conduit, and docking device. This design features a docking device on the surface of the combined conduit, allowing the docking insert from another MBR filtration module to be inserted into the right end of the docking sleeve and attached to the sealing ring surface. Rotating the knob then engages the limiting rod with the docking insert, fixing the docking insert to the right end of the docking sleeve via the limiting rod. This achieves a more convenient and faster docking when the combined conduit needs to be docked. A sealing structure is provided at the right end of the docking sleeve; a threaded sleeve is fitted onto the right end of the docking sleeve and rotated to insert a plug into the right end of the docking sleeve, sealing the right end of the combined conduit through the sealing ring, thus preventing two outlets.

[0004] Although the device has many beneficial effects, it still has the following problems: Traditional MBR filter membrane modules generally adopt a threaded sleeve and a single sealing ring structure. The sealing performance of the threaded connection will decline as the material ages, leading to an increase in leakage rate after long-term use. Secondly, the integral frame structure means that replacing a single membrane unit requires disassembling the entire system, resulting in long average maintenance time. Utility Model Content

[0005] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0006] 1. Technical problems to be solved:

[0007] To address the aforementioned issues of sealing structure defects and time-consuming disassembly and maintenance, this utility model is proposed.

[0008] Therefore, the purpose of this utility model is to provide a combined MBR filtration membrane module with a three-stage dynamic sealing system. A sealing ring one is designed on the end face of the connecting pipe, achieving an end-face sealing layer through fluid pressure. A sealing ring two is designed on the outer circumference of the connecting pipe, forming a radial sealing layer. Finally, a sealing ring three is designed on the inner circumference of the cap, forming an emergency sealing layer. This effectively improves the sealing performance of the connection between the connecting pipe and the cap. Simultaneously, magnetic attraction through a metal ring and magnetic ring structure enhances the connection stability between the cap and the connecting pipe. Furthermore, a quick-release modular frame is designed, with a support bar structure inside the frame and a spring-loaded limiting hemispherical locking structure on the top of the support bar's side wall. Additionally, an installation block structure with a limiting groove is designed in the membrane unit. The support bar, in conjunction with the support frame three, facilitates the disassembly and installation of the membrane unit, shortening the time required for each disassembly and maintenance.
