Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 3 As shown, this embodiment discloses a filter cartridge filtration performance testing device, including a source water tank 1, a first pipeline 3, a main pump 4, a second pipeline 5, a first switching valve 6, multiple testing components, a third pipeline 11, and a pure water tank 12.

One end of the outlet pipe 10 is connected to the side of the filter element mounting base 9 and the other end is connected to the third pipe 11. One end of the third pipe 11 is connected to the source water tank 1, and the other end of the third pipe 11 is connected to the eleventh switch valve 41. The source water tank 1 and the first pipe 3 are connected or blocked by the ball valve 2 located at the source water tank 1. The pure water tank 12 and the first pipe 3 are connected or blocked by the ball valve 2 located at the pure water tank 12.

[0024] The test assembly includes a wastewater pipe 13, one end of which is connected to a filter element mounting base 9 and the other end is connected to a fourth pipe 15. The two ends of the fourth pipe 15 are respectively connected to a fourth switch valve 16 and a fifth switch valve 17. The other end of the fourth switch valve 16 is connected to a pure water tank 12. The assembly also includes a wastewater tank 22. The end of the fifth switch valve 17 away from the fourth pipe 15 is connected to a fifth pipe 18. The other end of the fifth pipe 18 is connected to a sixth switch valve 19. The fifth pipe 18 and the wastewater tank 22 are connected through a sixth pipe 20. A seventh switch valve 21 is connected inside the sixth pipe 20. The wastewater tank 22 and the fifth pipe 18 are connected or disconnected through the seventh switch valve 21.

[0025] When conducting retention rate and filtration performance tests on the filter element in the filter element mounting base 9, ball valve 2, first switch valve 6, eleventh switch valve 41, fourth switch valve 16, and sixth switch valve 19 located at the pure water tank 12 are closed, while ball valve 2, fifth switch valve 17, and seventh switch valve 21 located at the source water tank 1 are opened. Through the main pump 4, the source water in the source water tank 1 is sequentially passed through the first pipe 3, the main pump 4, the second pipe 5, and the inlet pipe 7 into the filter element mounting base 9. The pure water filtered by the filter element in the filter element mounting base 9 flows out from the outlet pipe 10 and enters the pure water tank 12 for collection through the third pipe 11. The wastewater discharged from the filter element in the filter element mounting base 9 is discharged from the wastewater pipe 13 and sequentially passes through the fourth pipe 15, the fifth switch valve 17, the fifth pipe 18, the sixth pipe 20, and the seventh switch valve 21, finally entering the wastewater tank 22 for collection.

[0027] When pure water flow rate is tested, ball valve 2, first switch valve 6, eleventh switch valve 41, and third switch valve 14 located at source water tank 1 are closed, while ball valve 2, second switch valve 8, and regulating valve 36 located at pure water tank 12 are opened. Through the main pump 4, the pure water in pure water tank 12 passes sequentially through the first pipe 3, main pump 4, second pipe 5, inlet pipe 7, second switch valve 8, and filter element mounting base 9. All the pure water filtered by the filter element in filter element mounting base 9 flows out from outlet pipe 10, passes through regulating valve 36, and enters third pipe 11, and finally enters pure water tank 12 from third pipe 11.

[0028] When performing a leakage performance test, the filter element in the filter element mounting base 9 should first close the third switch valve 14 and the regulating valve 36 during the filtration process to ensure that the filter element mounting base 9 is filled with liquid. Then, the main pump 4 should be adjusted to the maximum power, and the surface of the filter element mounting base 9 should be checked for the generation of air bubbles.

[0029] The wastewater pipe 13 is connected to a transparent tube 35, which allows the wastewater to be observed at the transparent tube 35 when the filter element is discharging wastewater.

[0030] A sampling tube 38 is connected to the side of the wastewater pipe 13 between the viewing tube 35 and the filter element mounting base 9. The sampling tube 38 is opened or closed by the tenth switch valve 39. By setting the sampling tube 38, wastewater can be sampled, which facilitates wastewater testing.

[0031] A first pressure gauge 33 is connected to the side of the inlet pipe 7. The first pressure gauge 33 can detect the liquid pressure in the inlet pipe 7 before entering the filter element mounting base 9. A second pressure gauge 37 is connected to the side of the outlet pipe 10. The second pressure gauge 37 is used to detect the liquid pressure in the outlet pipe 10. A flow meter 34 is connected to the wastewater pipe 13 located between the third switch valve 14 and the transparent tube 35. The flow meter 34 can detect the wastewater flow rate in the wastewater pipe 13.

[0032] like Figure 5 As shown, this embodiment also includes a backwashing system 100, which includes a flushing tank 23, a seventh pipe 24, an eighth switch valve 25, a flushing pump 26, an eighth pipe 27, and a sixth switch valve 19. One end of the seventh pipe 24 is connected to the flushing tank 23 and the other end is connected to the inlet of the flushing pump 26. The outlet of the flushing pump 26 is connected to one end of the sixth switch valve 19. The flushing tank 23 and the flushing pump 26 are connected or disconnected through the eighth switch valve 25. The other end of the first switch valve 6 is connected to a ninth pipe 40. The end of the ninth pipe 40 away from the first switch valve 6 is connected to a drain valve 28. The drain valve 28 is connected or disconnected from the sewage tank 22 through the ninth switch valve 29. A drain outlet 30 is connected between the drain valve 28 and the ninth switch valve 29.

[0033] When the device is used for a long time, it needs to be backwashed. Specifically, during backwashing, the fourth switch valve 16, regulating valve 36, main pump 4 and seventh switch valve 21 are closed, and the flushing pump 26 and drain valve 28 are opened. The water in the flushing tank 23 passes through the seventh pipe 24, the eighth switch valve 25, the flushing pump 26, the eighth pipe 27, the sixth switch valve 19, the fifth pipe 18, the fifth switch valve 17, the fourth pipe 15, the wastewater pipe 13, the filter element mounting base 9, the liquid inlet pipe 7, the second pipe 5, the first switch valve 6, the ninth pipe 40 and the drain valve 28, and is finally discharged to the outside from the drain outlet 30, thus realizing the backwashing of the filter element and the pipeline.

[0034] When it is necessary to empty the sewage tank 22, close the drain valve 28 and open the ninth switch valve 29 and the drain port 30 to empty the sewage tank 22.

[0035] The backwashing system 100 also includes a dosing tank 31 and a dosing pump 32. The inlet end of the dosing pump 32 is connected to the dosing tank 31 and the outlet end is connected to the eighth pipe 27. Through the above design, chemical cleaning of pipelines and filter elements can be achieved, effectively improving the cleaning effect.

[0036] In this embodiment, multiple water channels not only enable the detection and testing of filter cartridge retention rate, filtration performance, pure water flow rate, and leakage performance, achieving various performance tests, but also enable backwashing and chemical backwashing of the water channels, greatly improving the cleaning effect and detection accuracy of the water channels.
