Description

Technical Field

[0001] This utility model relates to the field of vibrating diaphragm assembly technology, specifically to an internal flow-dividing structure for a vibrating diaphragm assembly. Background Technology

[0002] As a core functional unit of membrane separation technology in wastewater treatment, vibrating membrane modules play a crucial role in solid-liquid separation and pollutant retention in mainstream processes such as membrane bioreactors (MBR) and vibrating membrane filtration systems. Their separation efficiency, anti-fouling capabilities, and operational stability directly determine the treatment load, effluent quality, and operating costs of the wastewater treatment system. In scenarios such as advanced municipal wastewater treatment, industrial wastewater purification, and decentralized rural wastewater treatment, vibrating membrane modules effectively suppress membrane fouling and increase membrane flux through mechanical vibration, offering significant advantages over traditional static membrane modules, including higher treatment efficiency and longer cleaning cycles.

[0003] For example, CN205710054U discloses a novel channel-type MBR plate membrane guide plate, including a frame, with flat membranes arranged on both sides of the frame, forming a cavity between two flat membranes. A water outlet nozzle communicating with the cavity is provided on the frame, and several protrusions are arranged within the cavity, forming channels between the protrusions. Simultaneously, through the guidance of the channels, the pressure is diverted, resulting in more uniform pressure distribution. Because the pressure is distributed, localized accumulation is avoided, thus improving overall working efficiency.

[0004] However, the wastewater distribution is severely uneven. Membrane units in the central area of ​​the module bear excessive flow loads, while membrane units in the peripheral areas are idle. This leads to a sharp drop in local membrane flux and a rapid increase in transmembrane pressure difference, resulting in obvious regional differences in membrane fouling and significantly shortening the overall lifespan of the module. At the same time, when wastewater flows through the gaps in the support frame and the gaps in the membrane units, it generates violent turbulence due to the lack of an orderly flow guiding structure. This not only increases the energy consumption of the influent system but also exacerbates the incomplete scouring and removal of pollutants on the membrane surface, forming a stubborn fouling layer. Therefore, it is urgent to design a flow-dividing structure inside the vibrating membrane module to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an internal flow-dividing structure for a vibrating membrane module to address the issues raised in the background art, such as severely uneven wastewater distribution, excessively high flow load on membrane units in the central region of the module, and idle membrane units in the peripheral region. This results in a sharp drop in local membrane flux, a rapid increase in transmembrane pressure difference, and significant regional differences in membrane fouling, drastically shortening the overall lifespan of the module. Furthermore, when wastewater flows through the gaps in the support frame and membrane unit slits, the lack of an orderly flow-guiding structure causes severe turbulence, which not only increases the energy consumption of the influent system but also exacerbates the problem of incomplete scouring and removal of contaminants from the membrane surface, leading to the formation of a stubborn fouling layer.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an internal flow-dividing structure for a vibrating membrane assembly, comprising a filter cylinder and vibrating membrane components, wherein multiple sets of vibrating membrane components are vertically installed inside the filter cylinder, a water injection pipe is installed at the center of the filter cylinder, the water injection pipe delivers pressurized water into the vibrating membrane components, a purified water pipe is installed at the left end of the vibrating membrane components, and a drain pipe is installed at the right end of the vibrating membrane components.

[0007] Preferably, multiple sets of threaded columns are fixed around the inner side of the filter cylinder, and a vibrating diaphragm is vertically inserted into the threaded columns. A buffer box is installed at the center of the top of the filter cylinder, and connection ports are opened at both the upper and lower ends of the buffer box. Multiple sets of irregularly shaped blocks are fixed at the bottom of the inner side of the buffer box.

[0008] Preferably, a sealing post is fixedly provided at the center of the bottom of the filter cartridge, the size of which fits and seals the bottom center of the vibrating diaphragm, and two flow-generating ring blocks are fixedly provided around the side of the sealing post.

[0009] Preferably, an overflow port is provided on the side of each of the two sets of diversion ring blocks, and the top of the two sets of diversion ring blocks contacts the bottom of the vibrating diaphragm.

[0010] Preferably, the water injection pipe is installed at the top center of the filter cylinder via a flange at the bottom end, and the bottom end of the water injection pipe extends into the buffer box. The bottom end of the buffer box is also fixed with a water injection pipe, and the bottom end of the water injection pipe extends to the inner side of the center of the vibrating diaphragm.

[0011] Preferably, the water purification pipe is installed on the bottom left side of the filter cylinder, and the top end of the water purification pipe extends upward to the inside left side of the vibrating diaphragm, with the top end of the water purification pipe being parallel to the vibrating diaphragm.

[0012] Preferably, the drain pipe is installed on the upper right side of the filter cylinder, and the bottom end of the drain pipe extends to the right side inside the vibrating diaphragm, with the bottom end of the drain pipe flush with the bottom end of the vibrating diaphragm.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This type of vibrating membrane assembly has an internal flow-dividing structure. By setting up water injection pipes, purified water pipes and drain pipes installed inside the filter cartridge to connect with the vibrating membrane in an alternating manner, the distribution range of purified water is improved, the high flow load at the center of the vibrating module is reduced, and the service life is improved. Multiple sets of irregularly shaped baffles inside the buffer box can buffer the water flow and effectively replenish the sides, thereby orderly guiding the flow to avoid generating severe turbulence and reducing energy loss.

[0014] This vibrating membrane assembly features an internal flow-dividing structure. By fixing multiple sets of threaded columns inside the filter cartridge, the installation stability of the vibrating membrane assembly is improved, thereby reducing the impact of water flow alignment and improving filtration stability. The flow-dividing ring block can effectively divert water from the bottom side, reducing drainage pressure and thus effectively improving the efficiency of wastewater filtration.
