[0025] The working principle of the present invention: Place the filter element to be detected on the conveyor belt 501 of the first conveying mechanism 5. The third motor 502 drives the driving roller 503 to rotate. The driving roller 503 drives the conveyor belt 501 to move. The conveyor belt 501 drives the filter element to move to the lifting block 601. The fourth motor 602 drives the second lead screw 606 to rotate. The second lead screw 606 drives the second lead screw nut 605 to move. The lifting plate 604 and the lifting rod 603 also move accordingly, so as to drive the lifting block 601 and the filter element on its top to move upward, and lift the filter element on the lifting block 601 to the detection pool 101. Under the action of the gravity of the filter element itself, the filter element falls between the support block 301 and the turning plate 302 along the lifting block 601 and the guiding plate. The second motor 401 drives the cam 403 to rotate. The cam 403 drives the first connecting rod 406 to move. The first connecting rod 406 drives the swing arm 407 to swing forward, so that the second connecting rod 410 drives the support block 301 to move forward along the second slide rail 413, thereby pushing the filter element forward and inserting the water outlet end of the filter element into the clamping pipe 102. Open the flow regulating valve to let tap water flow into the detection cell 101. Start the ultrasonic generator to make the ultrasonic vibrating rod vibrate to prevent the tap water in the detection cell 101 from precipitating, improving the accuracy of the detection results. Start the first water pump 106. The water in the detection cell 101 passes through the filter element, then through the clamping pipe 102 and the water pipe 104 and enters the detection box 105. Start the water quality detection probe to detect the water inside the detection box 105, obtain the data of nitrate concentration, turbidity and residual chlorine concentration in the water, and send the detection data to the microprocessor. The microprocessor judges whether the detected data of nitrate concentration, turbidity and residual chlorine concentration exceed the standard values according to the standard values, so as to judge whether the filter element is qualified (if any one of these three groups of values exceeds the standard, the filter element is unqualified; if none of these three groups of values exceeds the standard, the filter element is qualified), and then realizes the detection of the filtering effect of the filter element; After the detection is completed, drive the first lead screw 208 to rotate by the first motor 202. The first lead screw 208 drives the first lead screw nut 207 to move upward. The nut mounting seat 206 and the lifting plate 201 also move upward accordingly. After the lifting plate 201 moves to the top of the detection cell 101, the piston rod of the first air cylinder 305 extends to push one end of the turning plate 302 to swing downward, so that the turning plate 302 swings by a set angle. The filter element between the turning plate 302 and the support block 301 will fall along the turning plate 302 onto the conveyor belt of the second conveying mechanism 7. When the filter element falling on the second conveying mechanism 7 is qualified, the second conveying mechanism 7 conveys the qualified filter element. When the filter element falling on the second conveying mechanism 7 is unqualified, the microprocessor controls the piston rod of the second air cylinder 802 to extend to push the pushing plate 801 to move. The pushing plate 801 pushes the unqualified filter element on the second conveying mechanism 7 to the chute 807, and the unqualified filter element slides down along the chute 807 into the recycling box 808 to remove and collect the unqualified filter element.
