Therefore, they should not be understood as limitations on the present invention.

[0026] This embodiment discloses a device for ultrafiltration system microbial contamination prevention experiment. By setting the ultrafiltration membrane tube 3, microorganisms in wastewater can be filtered to prevent microbial contamination from interfering with the wastewater experiment. Figure 1-Figure 7 It mainly includes a frame 1, on which a number of ultrafiltration membrane tubes 3 for filtering microorganisms in wastewater are symmetrically installed through a clamping component 5 (the ultrafiltration membrane tube 3 is a physical filtration method that efficiently separates and removes microorganisms in wastewater; this filtration effect is mainly due to the special pore structure and molecular sieve effect of the ultrafiltration membrane tube 3, the pore size range of which is usually between 0.001 and 0.1 microns, which can allow molecules in wastewater to pass through while retaining solute molecules larger than the pore size. Since it is an existing equipment, it will not be described in detail). An inlet pipe 2 and an outlet pipe 4 are respectively installed at both ends of the ultrafiltration membrane tube 3, and a circulation component 6 is installed between the inlet pipe 2 and the outlet pipe 4. Through the ingenious design of the circulation component 6, the filtered wastewater can be filtered again, thereby achieving a better filtration effect.

[0027] In order to clamp and fix the ultrafiltration membrane tube 3. In this embodiment, refer to Figure 1-Figure 7, the clamping assembly 5 includes a mounting plate 501, a gear 502, a first connecting rod 503, a clamping plate 504, a second connecting rod 505, a cover plate 506 and a driving assembly 7, the mounting plate 501 is fixedly connected to the frame 1, and the gears 502 are symmetrically rotatably connected on both sides of the upper end of the mounting plate 501, and each gear 502 is fixedly connected to a first connecting rod 503, and the end of the first connecting rod 503 away from the gear 502 is rotatably connected to the clamping plate 504 that can clamp the ultrafiltration membrane tube 3, and the second connecting rod 505 is rotatably connected to the mounting plate 501, and the end of the second connecting rod 505 away from the mounting plate 501 is rotatably connected to the clamping plate 504, and a driving assembly 7 that can drive the two gears 502 at the same time is installed in the middle of the upper end of the mounting plate 501, and the mounting plate 501 is covered with a cover plate 506;

[0028] When the ultrafiltration membrane tube 3 is clamped and fixed, the gear 502 is rotated through the driving component 7, and the gear 502 drives the first connecting rod 503 to rotate, and the first connecting rod 503 drives the clamping plate 504 to rotate, and with the cooperation of the second connecting rod 505, the clamping plate 504 clamps and fixes the ultrafiltration membrane tube 3, which is convenient and quick; when the ultrafiltration membrane tube 3 needs to be disassembled, the gear 502 is rotated in the opposite direction through the driving component 7, and then the gear 502 drives the first connecting rod 503 to rotate, and the first connecting rod 503 drives the clamping plate 504 to rotate, and with the cooperation of the second connecting rod 505, the clamping plate 504 no longer clamps the ultrafiltration membrane tube 3, which facilitates the disassembly of the ultrafiltration membrane tube 3.

[0029] In order to make the gear 502 rotate. In this embodiment, refer to Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7 The driving assembly 7 includes a threaded barrel 701, a threaded rod 702 and a straight tooth plate 703. The threaded barrel 701 is installed on the mounting plate 501. The threaded barrel 701 is internally threaded with a threaded rod 702. The threaded rod 702 is rotatably mounted with a straight tooth plate 703 that engages with two gears 502 at the same time. During specific use, the threaded rod 702 is rotated, and with the cooperation of the threaded barrel 701, the threaded rod 702 is moved, and then the straight tooth plate 703 is moved, so that the gear 502 can be rotated as needed.

[0030] In order to facilitate the movement of the straight tooth plate 703. In this embodiment, refer to Figure 5 and Figure 6The straight tooth plate 703 is fixedly connected to the T-shaped rod 8 at one end close to the threaded rod 702. A groove 10 adapted to the T-shaped rod 8 is opened in the threaded rod 702. A retaining ring 11 is installed in the groove 10 to prevent the T-shaped rod 8 from slipping out. Through the coordinated design of the T-shaped rod 8, the groove 10 and the retaining ring 11, the threaded rod 702 can drive the T-shaped rod 8 to move left and right, thereby facilitating the forward or reverse rotation of the gear 502.

[0031] In order to facilitate the smooth movement of the straight tooth plate 703. Figure 4 、 Figure 5 and Figure 7 A limiting groove 9 is provided in the middle of the upper end of the mounting plate 501, and a limiting plate 12 adapted to the limiting groove 9 is fixedly connected to the middle of the lower end of the spur plate 703. Through the coordinated design of the limiting groove 9 and the limiting plate 12, the spur plate 703 can be limited, thereby making the spur plate 703 more effective when moving.

[0032] In order to protect the ultrafiltration membrane tube 3. In this embodiment, a sponge pad is installed in each clamping plate 504. Through the arrangement of the sponge pad, the ultrafiltration membrane tube 3 can be protected when clamped, preventing the ultrafiltration membrane tube 3 from being damaged when the clamping plate 504 is clamped.

[0033] In order to better filter the microorganisms in the wastewater. Figure 2 The circulation component 6 includes a circulation pipe 601 and a circulation pump 602. The two ends of the circulation pipe 601 are respectively connected to the water inlet pipe 2 and the water outlet pipe 4. The circulation pump 602 is installed on the circulation pipe 601. Through the coordinated design of the circulation pipe 601 and the circulation pump 602, the water in the outlet pipe 4 after filtration can flow into the water inlet pipe 2, and then the filtered water can be filtered again, so that the filtering effect is better.

[0034] In order to control the waste water in the water inlet pipe 2 and the water outlet pipe 4. Figure 1 and Figure 2 An inlet valve 201 is installed on the water inlet pipe 2, and an outlet valve 401 is installed on the water outlet pipe 4. By setting the inlet valve 201, the wastewater in the water inlet pipe 2 can be controlled, and by setting the outlet valve 401, the wastewater in the outlet pipe 4 can be controlled.

[0035] The working principle of the device for the ultrafiltration system microbial contamination prevention experiment of the present invention is as follows: when the device is used, when it is necessary to filter the microorganisms in the wastewater, the water inlet valve 201 and the water outlet valve 401 are opened, and the wastewater to be tested is passed through the water inlet pipe 2 into the ultrafiltration membrane tube 3, and the ultrafiltration membrane tube 3 filters the wastewater, and the filtered wastewater flows out from the water outlet pipe 4, and the circulation pump 602 is started to make the water in the water outlet pipe 4 flow into the water inlet pipe 2 through the circulation pipe 601, so that the filtered wastewater can be filtered again, thereby achieving a better filtering effect;

[0036] When it is necessary to fix the ultrafiltration membrane tube 3, the threaded rod 702 is rotated to move the threaded rod 702, and then the T-shaped rod 8 and the straight tooth plate 703 can be pushed to move, so that the gear 502 can be engaged with the gear 502 to rotate the gear 502. During the rotation of the gear 502, the gear 502 drives the first connecting rod 503 to rotate, and the first connecting rod 503 drives the clamping plate 504 to rotate. With the cooperation of the second connecting rod 505, the clamping plate 504 can rotate the ultrafiltration membrane. The tube 3 is clamped, and the ultrafiltration membrane tube 3 is fixed, which is convenient and quick; when the ultrafiltration membrane tube 3 needs to be disassembled, the threaded rod 702 is rotated in the opposite direction to move the threaded rod 702, thereby driving the straight tooth plate 703 to move in the opposite direction, so that the gear 502 is rotated in the opposite direction, and the clamping plate 504 no longer clamps the ultrafiltration membrane tube 3, which is convenient for disassembly of the ultrafiltration membrane tube 3. Compared with the existing structure fixed by metal clamps and bolts, the replacement efficiency of the ultrafiltration membrane tube 3 is greatly improved.
