[0059] Working principle: Please refer to Figure 1-Figure 14As shown, when in use, the staff pours the sampled sewage into the interior of the water collecting cover 24 inside the first installation groove 16, and then the staff uses the detection component through the PLC controller 5. At this time, the detection component will perform the first detection on the sewage inside the water collecting cover 24 inside the first installation groove 16. When the detection is completed, the PLC controller 5 will start the electromagnet 36 inside the installation plate 35, and then the electromagnet 36 will be energized to adsorb the iron ring 28, and then the iron ring 28 will drive the water collecting cover 24 to move downward, and make the multiple first connecting columns 33 squeeze the multiple first springs 32, and at the same time the water collecting cover The sewage inside 24 loses the gathering effect of the water collecting cover 24, and then the sewage will enter the first filter tank 17 through the first water inlet hole 20. At this time, the multiple filter screens 38 inside the filter box 25 will filter the large particles of impurities in the sewage, and then the staff will start the micro pump 10 through the PLC controller 5, and then the micro pump 10 will pump the sewage filtered once inside the first filter tank 17 into the water collecting cover 24 inside the second installation tank 19 through the filter core 51. In this process, the filter core 51 will filter the medium-sized particles of impurities in the sewage. After the above steps are completed, the staff The staff uses the detection component to perform a secondary detection on the sewage inside the water collecting cover 24 inside the second installation tank 19. When the secondary detection is completed, the staff uses the PLC controller 5 to start the electromagnet 36 inside the second installation tank 19 again. Similarly, the sewage inside the second installation tank 19 will enter the second filter tank 18 through the first water inlet hole 20. During this process, the filter cotton 43 inside the second filter tank 18 will filter the fine particles in the sewage. At this time, the staff uses the first micro air pump 8 through the PLC controller 5, and the first micro air pump 8 will draw outside air into The inside of the second filter tank 18, and then the increased air pressure inside the second filter tank 18 will drive the top plate 42 to move upward and squeeze the filter cotton 43. At this time, the filter cotton 43 is squeezed, causing the sewage inside it to enter the water collecting tray 27 inside the third installation tank 23 through the second water inlet hole 21. Then the staff uses the detection component through the PLC controller 5 to detect the sewage after the three filtrations, thereby achieving multi-stage filtration of the sewage and facilitating multiple detections of the sewage during the multi-filter process, so that the staff can promptly know the effect of the detection data after the sewage is filtered and purified.
