Description

Technical Field

[0001] This utility model relates to the field of PM membrane filter technology, specifically a disc-type PM membrane filter that is not easily clogged. Background Technology

[0002] The core component of a membrane filter is the filter membrane, which is a thin film with even smaller pores fabricated on a microporous support layer (support). There are many materials used to make filter membranes, which can be divided into organic membranes (such as polysulfone hollow fiber membranes) and inorganic membranes.

[0003] In the current process of rinsing disc-type PM membrane filters, water is directly added to the filter through a conduit, which can easily lead to inadequate rinsing and clogging.

[0004] According to CN117323826A, a non-clogging disc-type PM membrane filter includes a filter tank for holding the liquid to be filtered, a filter disc installed in the filter tank, and a suction pump. A filter membrane is disposed on the filter disc, and a receiving cavity for holding clean liquid is formed between the filter membrane and the filter disc. The suction pump is connected to the receiving cavity through a pipe. This application, by setting a filter disc in the filter tank, allows the liquid in the filter tank to enter the receiving cavity after being filtered by the filter membrane during use. The suction pump then pumps the liquid out of the receiving cavity, creating a certain vacuum within the receiving cavity, thereby continuously drawing the liquid from the filter tank into the receiving cavity, thus enabling continuous filtration and facilitating use.

[0005] As described above, existing disc-type PM membrane filters often become clogged during use due to inadequate cleaning, rendering them unusable and reducing their cleaning efficiency and working effectiveness. To address these issues, a non-clogging disc-type PM membrane filter has been proposed. Utility Model Content

By setting a rotating mechanism, the guide tube can be rotated in the inner cavity of the filter membrane plate, so that the spray head can spray high pressure on the inner wall of the filter membrane plate. Then, the filter material attached to the outer wall of the filter membrane plate is cleaned. Then, the wastewater containing the filter material is discharged to the outside through the leakage hole of the filter cylinder and the drain pipe. This enhances the cleaning effect of the disc-type PM membrane filter, makes the disc-type PM membrane filter less prone to clogging, and improves the working efficiency of the disc-type PM membrane filter, thereby solving the problems mentioned in the background art.

[0023] This utility model provides, for example Figures 1-4The disc-type PM membrane filter shown includes a filter tank 1 and a connector 2 installed on the top of the filter tank 1. A rotating mechanism 3 is provided on the top of the connector 2. A conduit 4 is fixedly connected to the inner cavity of the rotating mechanism 3. A pipe connector 5 is fixedly connected to the top of the conduit 4. A delivery pipe 6 is movably connected to the inner cavity of the pipe connector 5 through a waterproof bearing.

A control valve 9 is installed on the lower surface of the drain pipe 8. By setting the rotating mechanism 3, the conduit 4 can be driven to rotate in the inner cavity of the filter membrane plate 7, so that the spray head 11 can spray high pressure on the inner wall of the filter membrane plate 7. Then, the filter material attached to the outer wall of the filter membrane plate 7 is cleaned. Then, the wastewater containing the filter material is discharged to the outside through the drain pipe 8 through the leakage hole of the filter cylinder 10. This enhances the cleaning effect of the disc-type PM membrane filter, makes the disc-type PM membrane filter less prone to clogging, and improves the working efficiency of the disc-type PM membrane filter.

[0024] The filter membrane plate 7 is arranged in a circular shape. The end of the conduit 4 away from the delivery pipe 6 passes through the inner cavity of the filter membrane plate 7 and extends downward, which can facilitate the discharge of filtered wastewater. The installation between the conduit 4 and the filter membrane plate 7 is convenient, and the water supply in the conduit 4 can be used to rinse the filter membrane plate 7.

[0025] The rotating mechanism 3 includes a stepper motor 31, which is mounted on the top of the connector 2. The output shaft of the stepper motor 31 is fixedly connected to a drive gear 32, and a driven gear 33 meshes with the surface of the drive gear 32. The driven gear 33 is mounted on the upper surface of the guide tube 4. The surface of the guide tube 4, located in the filter membrane plate 7, is connected to a spray head 11. Multiple spray heads 11 are arranged in a circumferential shape from top to bottom on the surface of the guide tube 4. The stepper motor 31 provides driving force, and the cooperation of the drive gear 32 and the driven gear 33 can drive the guide tube 4 to rotate in the filter membrane plate 7, thereby driving the spray heads 11 mounted on the guide tube 4 to rinse the inside of the filter membrane plate 7 outward. Subsequently, the filter material attached to the outer wall of the filter membrane plate 7 is rinsed clean, which enhances the cleaning effect of the disc PM membrane filter, makes the disc PM membrane filter less prone to clogging, and improves the working efficiency of the disc PM membrane filter.

[0026] A filter cylinder 10 is provided on the surface of the filter membrane plate 7. Support blocks 18 are fixedly connected to the bottom of the filter cylinder 10 around its perimeter.

The inner diameter of the first drain pipe 14 is larger than the inner diameter of the conduit 4. A second drain pipe 15 is provided at the outer end of the drain outlet 13. Both ends of the inlet 12 are provided with inlet pipes 16. Through the cooperation between the inlet 12, inlet pipes 16, drain outlet 13, first drain pipe 14 and second drain pipe 15, water can be easily fed into and drained from the disc PM membrane filter, thereby achieving the filtration effect for sewage.

[0028] In practical use, the conveying pipe 6 and the conduit 4 are first connected by a pipe and a waterproof bearing, so that the rotation of the conduit 4 does not affect the water supply from the conveying pipe 6 to the conduit 4. Then, the stepper motor 31 provides driving force, and the cooperation of the drive gear 32 and the driven gear 33 drives the conduit 4 to rotate in the filter membrane plate 7, thereby driving the spray head 11 installed on the conduit 4 to perform high-pressure rinsing of the inside of the filter membrane plate 7. Then, the filter material attached to the outer wall of the filter membrane plate 7 is washed away, and the rinsing wastewater is discharged through the drain pipe 8. This enhances the cleaning effect of the disc PM membrane filter, makes the disc PM membrane filter less prone to clogging, and improves the working efficiency of the disc PM membrane filter.
