[0047] Working principle: Refer to Figures 1 to 10The first valve body 8 is controlled to open by the control device 2, and then the polypeptide solution that has been preliminarily purified is transported through the liquid inlet pipe 6.

The polypeptide solution entering the first liquid feeding bucket 7 collides with the spoiler 15 arranged on the first liquid feeding bucket 7, so that the polypeptide solution is scattered on the ultrafiltration membrane 30. The ultrafiltration membrane 30 filters out the macromolecular impurities in the polypeptide solution. The polypeptide solution passing through the ultrafiltration membrane 30 falls on the first liquid receiving bucket 10. The polypeptide solution on the inner surface of the first liquid receiving bucket 10 converges toward the axial direction of the first liquid receiving bucket 10, so that the flow The polypeptide solution flowing into the connecting pipe 9 enters the second liquid feeding bucket 12 and collides with the spoiler 15 in the second liquid feeding bucket 12, so that the polypeptide solution is scattered on the nanofiltration membrane 31. The polypeptide solution passing through the nanofiltration membrane 31 is further concentrated and purified and falls on the second liquid receiving bucket 14. The polypeptide solution on the inner surface of the second liquid receiving bucket 14 converges toward the axis direction of the second liquid receiving bucket 14, and thus flows into the liquid outlet pipe 13. Finally, the concentrated and purified polypeptide solution is transported to the subsequent freeze-drying equipment through the liquid outlet pipe 13, thereby completing the concentration and purification of the polypeptide solution. When the ultrafiltration membrane 30 needs to be replaced and cleaned after being used for a period of time, the replacement and cleaning of the ultrafiltration membrane 30 is achieved through the following process: the first valve body 8 is controlled to be closed by the control device 2, and then the rotating motor 16 close to the first valve body 8 is controlled to start by the control device 2, so that the rotating shaft 17 fixedly connected to the output end of the rotating motor 16 rotates, so that the rotating seat 18 fixedly connected to the rotating shaft 17 rotates, and then the connecting plate 19 arranged on the rotating seat 18 rotates around the axis of the rotating seat 18, thereby driving the flip shaft 20 rotatably connected to the connecting plate 19 to rotate around the axis of the rotating seat 18. Rotate around the axis of the rotating seat 18, so that the connecting seat 22 fixedly connected to the flip shaft 20 rotates around the axis of the rotating seat 18, driving the connecting frame 23 fixedly connected to the connecting seat 22 to rotate around the axis of the rotating seat 18, so that the longitudinal rod 24 arranged in the connecting frame 23 rotates around the axis of the rotating seat 18, driving the vibration block 28 slidably connected to the longitudinal rod 24 to rotate around the axis of the rotating seat 18, so that the separation cover 29 fixedly connected to the vibration block 28 rotates around the axis of the rotating seat 18, so that the ultrafiltration membrane 30 to be cleaned is rotated out; In the process of the ultrafiltration membrane 30 to be cleaned rotating toward the bottom of the nozzle 36, in the process of the rotating gear 21 meshing with the arc-shaped toothed plate 27, the rotating gear 21 is rotated, and then the flip shaft 20 fixedly connected to the rotating gear 21 rotates around the axis of the rotating seat 18 and also rotates, so that the connecting seat 22 fixedly connected to the flip shaft 20 rotates around the axis of the rotating seat 18 and also rotates, and then the connecting frame 23 fixedly connected to the connecting seat 22 rotates around the axis of the rotating seat 18 and also rotates, driving the longitudinal rod 24 arranged in the connecting frame 23 to rotate around the axis of the rotating seat 18 and also rotate, so that the vibration block 28 slidably connected to the longitudinal rod 24 drives the separation cover 29 to rotate around the axis of the rotating seat 18 and also rotates, when the rotating gear 21 is disengaged from the arc-shaped toothed plate 27, the ultrafiltration membrane 30 to be cleaned also rotates 180° at this time, until the infrared sensor 37 detects that the ultrafiltration membrane 30 flipped 180° rotates to the bottom of the nozzle 36; When the ultrafiltration membrane 30 flipped 180° rotates to the position directly below the nozzle 36, the second valve body 33 is opened by the control device 2 to allow the cleaning liquid to enter the main pipe 32, and the cleaning liquid in the main pipe 32 enters the branch pipe 34, and finally enters the nozzle 36 through the liquid spraying pipe 35. The nozzle 36 sprays the cleaning liquid on the ultrafiltration membrane 30 below, so as to wash away the macromolecular impurities removed from the ultrafiltration membrane 30, thereby completing the cleaning of the ultrafiltration membrane 30; When the cleaning liquid sprayed by the nozzle 36 falls on the ultrafiltration membrane 30 below, the cleaning liquid impacts the ultrafiltration membrane 30, so that the vibration block 28 fixedly connected to the separation cover 29 slides on the longitudinal rod 24.

When the nanofiltration membrane 31 flipped 180° rotates to the bottom of the nozzle 36, the control device 2 controls the second valve body 33 to open so that the cleaning liquid enters the main pipeline 32. The cleaning liquid in the main pipeline 32 enters the branch pipeline 34 and finally enters the nozzle 36 through the liquid spraying pipe 35. The nozzle 36 sprays the cleaning liquid on the nanofiltration membrane 31 below, thereby washing away the macromolecular impurities removed from the nanofiltration membrane 31 from the nanofiltration membrane 31, thereby completing the cleaning of the nanofiltration membrane 31.
