[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Please see Figs. 1 to 4 This utility model provides a technical solution: a multi-stage membrane filtration device for extracting tea polyphenols, including a fixed base 1, on which a fixed barrel 2 and a support barrel 3 are fixedly installed respectively. A fixed ring seat 9 and a support ring seat 16 are fixedly installed on the fixed barrel 2. Movable seats 6 are movably installed on the top of both the fixed barrel 2 and the support barrel 3. A drive motor 8 and a lifting mechanism 7 are fixedly installed on the movable seats 6. The lifting mechanism 7 is a linear reciprocating electric push rod that pushes a piston seat 19 to move up and down. A feed pipe 4 is fixedly installed on the side of the fixed barrel 2. A discharge pipe 12 is fixedly installed on the bottom of the support barrel 3. A sealing seat 10 is rotatably installed on the bottom of the fixed barrel 2. A partition plate 13 is welded inside the fixed ring seat 9. A first filtration mechanism 14 is fixedly installed between the fixed ring seat 9 and the fixed barrel 2. The first filtration mechanism 14, the second filtration mechanism 18, and the third filtration mechanism 23 are all membrane filtration structures, and the filter holes of the first filtration mechanism 14, the second filtration mechanism 18, and the third filtration mechanism 23 gradually decrease in size.

[0023] In this embodiment, a connecting pipe 15 is fixed inside the fixed ring seat 9, and a water pump 17 is installed at one end of the connecting pipe 15. The water pump 17 is fixedly installed inside the support ring seat 16. A second filter mechanism 18 is fixedly installed between the support ring seat 16 and the fixed barrel 2. A piston seat 19 is movably installed inside the fixed barrel 2. A movable column 20 is fixed on the piston seat 19. One end of the movable column 20 is installed on the lifting mechanism 7. The up and down movement of the piston seat 19 completes the squeezing filtration of the liquid.

[0024] In this embodiment, a centrifuge tank 22 is rotatably mounted inside the support tank 3. A rotating column 21 is fixed inside the centrifuge tank 22. One end of the rotating column 21 is mounted on the drive motor 8. A third filtration mechanism 23 is fixedly mounted on the centrifuge tank 22. A pipe 5 is fixed to the side of the support tank 3. The other end of the pipe 5 is mounted on a fixed ring seat 9. A support frame 11 is welded to the bottom of the fixed seat 1. The discharge pipe 12 is fixedly mounted on the support frame 11. The centrifuge tank 22 rotates to complete the active filtration of the liquid.

[0025] When using the device, the lifting mechanism 7 is activated to move the piston seat 19 upward. After the piston seat 19 moves upward, the liquid entering through the feed pipe 4 enters the bottom of the fixed tank 2. Then, the feed pipe 4 is closed, and the lifting mechanism 7 is activated to push the piston seat 19 downward. Under the compression of the piston seat 19, the liquid moves to the side and undergoes preliminary filtration through the second filter mechanism 18. The filtered liquid enters the interior of the column support ring seat 16. The water pump 17 is activated to draw the liquid inside the support ring seat 16 upward. The liquid moves upward and enters the top of the piston seat 19 through the connecting pipe 15. Then, the piston seat 19 moves upward, and after moving upward, it compresses the liquid again. Under the compression, the liquid undergoes secondary filtration through the first filter mechanism 14. After secondary filtration, the liquid enters the interior of the fixed ring seat 9 and is discharged into the interior of the support tank 3 through the pipe 5 on one side of the fixed ring seat 9. The liquid falls into the interior of the centrifuge tank 22 through the pipe 5. The drive motor 8 is started to drive the centrifuge tank 22 to rotate. The centrifuge tank 22 rotates and causes the liquid to pass through the third filtration mechanism 23 for secondary filtration. The filtered liquid is discharged from the discharge pipe 12, completing the extraction of tea polyphenols. The up and down movement of the piston seat 19 completes the compression filtration of the liquid. The compression accelerates the filtration of the liquid. In addition, the up and down movement of the piston seat 19 completes the scraping and cleaning of the filtration mechanism. After cleaning, the sealing seat 10 is opened and the piston seat 19 moves downward and moves out of the interior of the fixed tank 2, completing the cleaning of impurities.
