Description

Technical Field

[0001] This utility model relates to the field of vibrating membrane filtration technology, specifically to a vibrating membrane filtration mechanism. Background Technology

[0002] Building upon cross-flow filtration, the introduction of vibration enhancement technology has provided a new approach to solving membrane fouling. As a result, vibrating membrane filtration mechanisms have gradually matured. The core principle of vibrating membrane filtration is to drive the membrane module or feed liquid to generate periodic vibrations through external force, so that the membrane surface and the feed liquid form relative motion. The shear force and disturbance effect generated by this motion are much greater than those of static filtration or conventional cross-flow filtration, which can effectively inhibit the formation and thickening of the filter cake layer. Compared with cross-flow filtration, vibrating membrane filtration does not rely on high-flow-rate feed liquid circulation and can achieve excellent fouling suppression effect at a lower operating flow rate, significantly reducing energy consumption. For example, CN206897190U discloses a vertical spiral wound membrane vibration filtration device, including a vibration component and a membrane component. The vibration component is mounted on a support via an elastic mechanism, and the membrane component is directly and rigidly mounted on the vibration component. The membrane component is elastically connected to the support. Under the left-right, up-down, or multi-vibration forces of the vibration component, the membrane component can disrupt the crystallization conditions of easily fouling substances, reduce the retention layer on the membrane surface, and increase the shear force on the membrane surface, making it difficult for pollutants to accumulate on the membrane surface and in the inlet channel, thus preventing membrane clogging. Furthermore, the membrane component is directly mounted on the vibration component, resulting in high vibration efficiency and good effect, further improving… While improving membrane treatment efficiency and avoiding excessive rinsing and chemical cleaning, this method extends the lifespan of spiral wound membrane elements and reduces operating costs. However, current equipment uses a vibrating device for periodic vibration during filtration, which transfers vibration energy to the membrane module via connectors, resulting in significant energy loss. This leads to uneven vibration intensity on the membrane surface, causing filter cake buildup in some areas and inconsistent filtration performance. Furthermore, the vibration mechanism is prone to resonance, affecting equipment stability and reducing overall lifespan. Therefore, there is an urgent need to design a vibrating membrane filtration mechanism to address these issues. Utility Model Content

[0003] The purpose of this utility model is to provide a filtration mechanism for a vibrating membrane, in order to solve the problems mentioned in the background art. When the current equipment is used for filtration, the vibration energy needs to be transferred to the membrane module through the connecting parts during the periodic vibration of the vibrating device. In this process, the energy loss is relatively large, resulting in uneven vibration intensity on the membrane surface. In some areas, filter cake is still easy to accumulate, and the filtration effect is inconsistent. At the same time, the mechanism is prone to resonance during the vibration process, which affects the stability of equipment operation and reduces the overall service life.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a filtration mechanism for a vibrating membrane, comprising a filter housing, a sealing round cover, and a permeate tube, wherein a spiral membrane is installed at the center of the filter housing, and sealing round covers are installed at the upper and lower ends of the filter housing, the spiral membrane can be quickly adjusted inside the filter housing, and a permeate tube is installed at the center of the filter housing.

[0005] Preferably, the filter housing has a liquid outlet at the bottom center, a feed inlet at the bottom left end, and a discharge outlet at the top right end.

[0006] Preferably, a base plate is placed on the inner bottom side of the filter housing. The base plate is made of an elastic material and contacts the internal spiral wound membrane assembly to reduce polarization.

[0007] Preferably, four sets of inner slide rails are fixedly fitted to the inner wall of the filter housing, and each set of inner slide rails is equipped with a clamping component, which clamps the spiral membrane assembly from top to bottom.

[0008] Preferably, the clamping member includes an upper clamp and a lower clamp, the upper clamp and the lower clamp have the same structure and are mirror images of each other, the upper clamp and the lower clamp are perpendicular to each other, and the upper clamp and the lower clamp slide up and down within corresponding inner slide rails.

[0009] Preferably, the single set of upper clamps includes a trapezoidal slider and a fixed arc block. The fixed arc block is fixed to the inner wall of the trapezoidal slider. An inner arc groove is opened on the inner side of the fixed arc block. A sliding arc block is provided in the inner arc groove. An outer arc groove is opened on the inner side of the sliding arc block. A filter membrane assembly is installed in the outer arc groove.

[0010] Preferably, the outer arc-shaped groove has a docking hole, the docking hole is threaded to the filter membrane assembly, and the sliding arc-shaped block slides slightly within the inner arc-shaped groove of the fixed arc-shaped block.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This vibrating membrane filtration mechanism allows the membrane module inside the filter housing to contact the bottom plate, thereby reducing resonance and improving the overall service life. The membrane module can be clamped and installed using four sets of inner slide rails and clamping parts. This design allows the membrane module to vibrate periodically in four squares, thereby increasing the vibration range, preventing filter cake formation in some areas, and improving the filtration effect.

[0012] This vibrating membrane filtration mechanism improves the sealing effect by connecting the sealing round cover and the top of the filter housing with a flange. It also facilitates disassembly for backwashing, thereby improving the internal cleaning efficiency. After the sliding arc block is connected to the membrane module, the periodic vibration can slide within the inner arc groove of the fixed arc block, further avoiding resonance and improving the applicability of the device.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-5 One embodiment provided by this utility model: A vibrating membrane filtration mechanism includes a filter housing 1, a sealing round cover 2, and a permeate tube 3. A spiral membrane is installed in the center of the filter housing 1, and the sealing round cover 2 is installed at the upper and lower ends of the filter housing 1. The spiral membrane can be quickly adjusted inside the filter housing 1, and the permeate tube 3 is installed in the center of the filter housing 1.

[0017] As a further feature of this invention, a liquid outlet 103 is provided on the bottom center side of the filter housing 1, a feed inlet 101 is provided on the bottom left side of the filter housing 1, and a discharge outlet 102 is provided on the upper right side of the filter housing 1, which facilitates the filtration of wastewater and improves efficiency.

[0018] Furthermore, a base plate 11 is placed on the bottom side inside the filter housing 1. The base plate 11 is made of elastic material. The base plate 11 contacts the internal spiral wound membrane assembly to reduce polarization. This design facilitates contact with the internal membrane assembly, thereby reducing polarization and improving the service life of the device.

[0019] Furthermore, four sets of inner slide rails 12 are fixedly fitted to the inner wall of the filter housing 1. Each set of inner slide rails 12 is equipped with a clamping component 13. The clamping component 13 clamps the spiral membrane module from top to bottom. The clamping component 13 includes an upper clamp 131 and a lower clamp 132. The upper clamp 131 and the lower clamp 132 have the same structure and are mirror images of each other. The upper clamp 131 and the lower clamp 132 are perpendicular to each other. The upper clamp 131 and the lower clamp 132 slide up and down within the corresponding inner slide rails 12. This design is beneficial for the stable clamping of the membrane module after clamping, thereby improving the vibration efficiency and smoothly vibrating the membrane module within a range, thus improving the vibration efficiency.

[0020] Furthermore, the single-unit upper clamp 131 includes a trapezoidal slider 1311 and a fixed arc block 1312. The fixed arc block 1312 is fixedly mounted on the inner wall of the trapezoidal slider 1311. An inner arc groove 1313 is opened on the inner side of the fixed arc block 1312. A sliding arc block 1314 is provided in the inner arc groove 1313. An outer arc groove 1315 is opened on the inner side of the sliding arc block 1314. A filter membrane assembly is installed in the outer arc groove 1315. A docking hole 1316 is opened in the outer arc groove 1315. The docking hole 1316 is threaded to the filter membrane assembly. The sliding arc block 1314 slides slightly in the inner arc groove 1313 in the fixed arc block 1312. This design facilitates the periodic small-amplitude vibration of the clamping component, which is different from the vibration amplitude of the filter shell, thereby avoiding resonance and improving the overall service life.

[0021] Working principle: In use, the user first threadedly installs the membrane module side to the corresponding docking hole 1316 of the outer arc groove 1315 in the sliding arc block 1314 of the clamping member 13. After installation, the trapezoidal slider 1311 moves up and down in the inner slide rail 12 until the center of the membrane module is aligned with the permeate pipe 3. Then, the sealing round cover 2 and the filter housing 1 are sealed with bolts. The wastewater can then be treated by the equipment. When the membrane module vibrates, the connecting member 13 can vibrate synchronously. The four sets of connecting members 13 are the same, which can vibrate the membrane module relative to each other, thereby reducing the generation of filter cake. When the clamping member 13 vibrates, the sliding arc block 1314 vibrates and can slide back and forth in a small amplitude in the inner arc groove 1313 inside the fixed arc block 1312. The above is the complete working principle of this utility model.
