[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Example 1, referring to Figure 1-4 An adjustable flow rate ultrafiltration tank feed and discharge device includes two pipe mechanisms that are sequentially fixed and connected to the feed end and discharge end of the ultrafiltration tank 1. Each pipe mechanism includes a length adjustable pipe assembly and a flow rate intelligent adjustment assembly. Specifically, the flow intelligent regulation component includes a driver, a flow sensor 3 installed on the main pipeline 2, a fixed cover 4 fixedly connected to the top outer wall of the main pipeline 2, a valve stem shaft 5 that is connected through a sealed bearing to the top inner wall of the main pipeline 2, a valve core 6 fixedly connected to the bottom end of the valve stem shaft 5 and adapted to the main pipeline 2, and a control panel 22 fixedly connected to the outer wall of the ultrafiltration tank 1 through a support plate 21. Furthermore, the driver includes a stepper motor 7 fixedly mounted on the side wall of the fixed cover 4, a driving bevel gear 8 fixedly mounted on the output shaft of the stepper motor 7, and a driven bevel gear 9 fixedly mounted on the top of the valve stem shaft 5. The output shaft of the stepper motor 7 extends through the fixed cover 4. The driving bevel gear 8 and the driven bevel gear 9 mesh with each other and are both located inside the fixed cover 4. The flow sensor 3 and the stepper motor 7 are both electrically connected to the control panel 22. When the driver is running, the driving bevel gear 8 is driven to rotate by the stepper motor 7. Subsequently, the driven bevel gear 9 meshing with the driving bevel gear 8 will drive the valve core 6 at the bottom of the valve stem shaft 5 to rotate, thereby allowing flexible adjustment of the opening degree of the valve core 6. The working principle of this embodiment is as follows: By setting the required feed flow rate and discharge flow rate on the control panel 22, the flow sensors 3 at the feed end and discharge end respectively detect the feed flow rate and discharge flow rate in real time, and transmit the detected data to the control panel 22 in real time. The control panel 22 will control the two drives to work in real time according to the received data to flexibly adjust the opening and closing degree of the valve core 6 in the respective areas of the feed end and discharge end to achieve the required feed flow rate and discharge flow rate. In this way, the feed flow rate and discharge flow rate of the ultrafiltration tank feed and discharge device can be flexibly, intelligently and accurately controlled, ensuring the stability of the ultrafiltration process.

[0016] Example 2, refer to Figure 1-2 and Figure 4-7 This embodiment is an optimization based on embodiment 1. Specifically, the length adjustable pipe assembly includes a main pipe 2, a telescopic pipe 10 with a flange 13 fixedly connected to the end, and a telescopic controller. More specifically, the telescopic controller includes a hollow cylinder 14 fixedly connected to the top outer wall of the main pipe 2, a threaded rotating rod 15 rotatably installed inside the hollow cylinder 14, a telescopic rod 16 threadedly connected to the threaded rotating rod 15, a control shaft 17 rotatably installed on the top of the hollow cylinder 14, a worm gear 18 fixedly mounted on the control shaft 17, and a worm wheel 19 fixedly mounted on the threaded rotating rod 15; furthermore, the end of the telescopic rod 16 is fixedly connected to the flange 13, the outer wall of the telescopic rod 16 is slidably connected to the inner wall of the hollow cylinder 14, the worm gear 18 and the worm wheel 19 mesh with each other and are both located inside the hollow cylinder 14, and a rotating cap 20 is fixedly connected to the top outer wall of the control shaft 17; Furthermore, four annularly distributed sealing strips 11 are fixedly connected to the outer wall of the telescopic pipe 10, and four annularly distributed sealing slots 12 are opened on the inner wall of the main pipe 2. The four sealing strips 11 are respectively sealed and inserted into the four sealing slots 12. In this way, the sealing between the main pipe 2 and the telescopic pipe 10 can be facilitated through the sealing and insertion cooperation between the four sealing strips 11 and the four sealing slots 12. The working principle of this embodiment is as follows: First, the worm gear 18 on the control shaft 17 can be driven to rotate in both directions by the rotating cap 20. Then, the worm wheel 19 meshing with the worm gear 18 will drive the threaded rotating rod 15 to rotate in both directions. In turn, the telescopic rod 16 threadedly connected to the threaded rotating rod 15 will drive the telescopic pipe 10 to move in and out. Second, when the telescopic pipe 10 extends outward, it will increase the connection length of the entire pipe mechanism. When the telescopic pipe 10 retracts inward, it will shorten the connection length of the entire pipe mechanism. In this way, the connection length of the pipe mechanism can be flexibly adjusted to prevent the situation where it is inconvenient to connect with the external pipeline when the pipe distance is too long or too short. Finally, the connection length of the two pipe mechanisms on the feed end and discharge end of the ultrafiltration tank 1 is adjusted to a suitable length in the above manner. Then, the two flanges 13 are used to connect with the external pipeline. The liquid to be filtered will enter the ultrafiltration tank 1 from the upper pipe mechanism through the feed end to complete the feeding work. The liquid filtered by the ultrafiltration tank 1 will be discharged from the lower discharge end through the pipe mechanism above to complete the discharge work.
