[0039] Multiple fiber membrane filaments 4 are fixedly connected to the membrane frame 3, and the moving frame 9 is slidably connected to the fixing pin 10;

[0040] In this embodiment, when the wastewater flows into the membrane housing 1, it will push the impeller 8 to rotate. The rotation of the impeller 8 can cause the first rotating shaft 7 to rotate. The rotation of the first rotating shaft 7 can drive the elliptical wheel 12 to rotate. Then, under the action of the spring 11 and the fixing pin 10, the rotation of the elliptical wheel 12 can cause the two moving frames 9 to continuously move back and forth. In this way, the fiber membrane filaments 4 can be continuously shaken. Moreover, when the water is flowing, it will also generate a hydraulic shear force on the fiber membrane filaments 4. Cooperating with the continuous shaking of the fiber membrane filaments 4 can effectively prevent impurities and pollutants from adhering to their surfaces, thereby achieving the effect of cleaning impurities;

[0041] Among them, in order to achieve the purpose of draining water, the following technical solution is adopted by this device: A first pipe 13 is fixedly embedded inside the cover plate 2. The bottom end of the first pipe 13 extends into the first cavity. The first pipe 13 is fixedly connected to the membrane frame 3;

[0042] Among them, in order to achieve the purpose of preventing water leakage, the following technical solution is adopted by this device: A sealing gasket 14 is fixedly connected to the bottom of the cover plate 2. The sealing gasket 14 is in contact with the top of the membrane housing 1. Connecting strips 15 are fixedly connected to both sides of the membrane housing 1. The cover plate 2 is bolted to the two connecting strips 15. The sealing gasket 14 can prevent water leakage between the cover plate 2 and the membrane housing 1;

[0043] Among them, in order to achieve the purpose of enabling the wastewater to normally push the impeller 8 to rotate, the following technical solution is adopted by this device: A booster pump 16 is provided on one side of the membrane housing 1. The water outlet of the booster pump 16 is fixedly connected to a second pipe 17. The end of the second pipe 17 is fixedly embedded on one side of the membrane housing 1. The water inlet of the booster pump 16 is fixedly connected to a third pipe 18. A flange 19 is fixedly sleeved outside the third pipe 18. By controlling the booster pump 16 to work, the wastewater can be conveyed, thereby accelerating the flow of the wastewater, and further ensuring that the wastewater can normally push the impeller 8 to rotate;

[0044] Among them, in order to achieve the purpose of reducing wear, the following technical solution is adopted by this device: The first rotating shaft 7 is connected to the column 5 and the connecting plate 6 through a sealed bearing. Connecting through a sealed bearing can reduce wear.

[0045] The usage process of the present utility model is as follows: When using the present utility model, through the design of the flange 19, the device can be installed on the pipeline where municipal wastewater flows using bolts. Then, the wastewater can flow into the membrane housing 1 through pipeline three 18 and pipeline two 17. Then, multiple hollow fiber membrane filaments 4 in the membrane housing 1 can filter the impurities in the wastewater. When filtering, the wastewater will pass through the micropores on the fiber membrane filaments 4 and enter the interior of the fiber membrane filaments 4, and then enter cavity one, and finally be discharged through pipeline one 13, thereby realizing the filtration of wastewater;

[0046] Among them, when filtering, the wastewater passes through the micropores and enters the interior of the fiber membrane filaments 4, while the impurities will adhere to the surface of the fiber membrane filaments 4. When too many impurities adhere, it will affect the filtration of the wastewater. It should be noted that when the wastewater flows, it will drive the impeller 8 to rotate. The rotation of the impeller 8 can cause the first rotating shaft 7 to rotate. The rotation of the first rotating shaft 7 can drive three elliptical wheels 12 to rotate. Then, under the action of the spring 11 and the fixing pin 10, the rotation of the three elliptical wheels 12 can cause the two moving frames 9 to continuously move back and forth, so that the fiber membrane filaments 4 can continuously vibrate. And when the water flows, it will also generate a hydraulic shear force on the fiber membrane filaments 4. Cooperating with the continuous vibration of the fiber membrane filaments 4 can effectively prevent impurities and pollutants from adhering to its surface, thereby achieving the effect of cleaning impurities, further slowing down membrane fouling. And the device realizes the rotation of the impeller 8 through the force of the flowing wastewater when cleaning impurities, without the need to additionally add a power source, which can achieve the effect of energy saving and conforms to the concept of green environmental protection;

[0047] When the flow rate of the wastewater is insufficient, the booster pump 16 can be controlled to work, so as to convey the wastewater, thereby accelerating the flow of the wastewater, and further ensuring that the wastewater can normally drive the impeller 8 to rotate;

[0048] When treating the wastewater, the fiber membrane filaments 4 filter the impurities, so that the impurities will remain in the membrane housing 1. Since the cover plate 2 and the connecting strip 15 are connected by bolts, when the impurities need to be cleaned, the bolts can be unscrewed, and then components such as the cover plate 2, the connecting plate 6, the membrane frame 3, the fiber membrane filaments 4, the column 5, the impeller 8, the first rotating shaft 7, the eccentric wheel, the fixing pin 10, and the spring 11 can be removed from the membrane housing 1, and then the impurities can be cleaned.

[0049] The above is only a preferred embodiment of the present utility model. Any person skilled in the art may modify the present utility model by using the technical solutions described above or modify it into an equivalent technical solution. Therefore, any simple modification or equivalent replacement made according to the technical solutions of the present utility model belongs to the scope of protection required by the present utility model.
