[0044] Working principle: the filter paper board is cut into a circle for detection, as shown in Figure 1 , the bottom cylinder 2 is started, the bottom cylinder 2 drives one of the two support plates two 4 to move, the fixed cylinders 27 in the two support plates two 4 are away from each other, the filter paper board is placed on the mounting groove 37 (as shown in Figure 2 ), and then the fixed cylinders 27 are reversely driven to clamp the filter paper board. First, the whole detection is carried out, water is supplied into the support rod 5, (the shape of the support rod 5 is as shown in Figure 9 , Figure 10 ), the water enters between the encapsulation cylinder 22 and the middle cylinder 23 through the water passage 24, and then flows into the water containing ring 21, and then flows out of the pressurizing cylinder 18. Subsequently, the rotating cylinder 26 and the fixed cylinder 27 are filled with water, and after the filter paper board is soaked, the pressure is adjusted, the pressure in the rotating cylinder 26 is changed by the water injection pressure, the pressure in the two detection assemblies is inconsistent, that is, the pressure on both sides of the filter paper board is inconsistent, then water is injected into the rotating cylinder 26 in one of the detection assemblies, and water is discharged in the other detection assembly, so as to test the filter speed.

[0045] The rotating driving mechanism comprises a motor 9 fixedly arranged on the fixed cylinder 27, a gear 10 fixedly arranged on the rotating shaft of the motor 9, the gear 10 and a large gear ring 11 are meshed with each other, the rotating driving mechanism drives the connecting ring 28 integrated with the large gear ring 11 to rotate through the rotation of the gear 10, the connecting ring 28 drives the spherical connecting rod 13, the spherical connecting rod 13 drives the sliding rod 14, the sliding rod 14 drives the center ring 17, and the center ring 17 drives the pressurizing cylinder 18 to move away from the filter paper board. When the whole detection is carried out, it is in this state, when the local detection is carried out, the connecting ring 28 is continuously rotated, the protruding block 12 on the connecting ring 28 will contact the actuating piece 25, and the rotating cylinder 26 is rotated by the actuating piece 25 (as shown in Figure 6When the cam 26 is in the closed position, the cam 26 is in the closed position, and the cam 26 is in the closed position, so that the cam 26 is in the closed position.

[0046] Edge detection starts the switching electric cylinder 6, which drives the central moving shaft 7 to move, and the central moving shaft 7 drives the blocking shaft 36 to press the filter paper board tightly. The central moving shaft 7 is located inside the intermediate cylinder 23, and the blocking shafts 36 in the two detection components press the filter paper board from both sides. At this time, the pressurizing cylinder 18 is placed away from the filter paper board, and then water is injected through the pressurizing cylinder 18. The middle position of the filter paper board is pressed by the blocking shaft 36, and at this time only the edge position of the filter paper board is detected.

[0047] In the three detection methods, water passes through the pressurized cylinder 18. In the water inlet detection component, water enters the water pipe 24, then passes through the gap between the intermediate cylinder 23 and the packaging barrel 22 into the water holding ring 21, and then enters the pressurized cylinder 18 from the water holding ring 21. The interior of the intermediate cylinder 23 is separated from the interior of the water holding ring 21 by the intermediate cylinder 23, and the sealing disk 20 abuts one end of the intermediate cylinder 23. The water finally enters the rotating cylinder 26 from the pressurized cylinder 18. During the overall detection, the pressurized cylinder 18 leaves the filter paper board, and water is filled into the rotating cylinder 26 through the pressurized cylinder 18 for detection. During local detection, the pressurized cylinder 18 presses against the filter paper board and water is passed through for detection. During edge detection, the sealing shaft 36 presses against the filter paper board, and the pressurized cylinder 18 is located between the sealing plate and the rotating cylinder 26 and the pressurized cylinder 18 does not contact the filter paper board. Then water is passed through the pressurized cylinder 18 to the position between the sealing shaft 36 and the rotating cylinder 26 for detection.

[0048] A method for detecting the filtration rate of a filter paperboard comprises the following steps:

[0049] Step 1: Installation: Place the filter paper between the two test components and clamp it tightly, using the metal grid as support;

[0050] Step 2: Prepare for testing. Fill the rotating cylinder 26 and the fixed cylinder 27 with water and pressurize them. Wait until the filter paper is completely soaked, and then pressurize them again to make the pressure on both sides of the filter paper different.

[0051] Step three: overall detection, water is added to one of the detection components, the other detection component is used to discharge water, and the flow rate is tested.

[0052] Step four: local detection, the pressurizing cylinders 18 of the two detection components are pressed against the filter paper board, water is added to the pressurizing cylinders 18 to pressurize, different pressures are applied to the two sides of the filter paper board to test the flow rate, and the pressurizing cylinders 18 rotate around the shaft of the fixing cylinder 27 to test different positions.

[0053] Step five: edge detection, the blocking shaft 36 of the two detection components is pressed against the filter paper board, and water is added to the blocking shaft 36 and the mounting groove 37 through the pressurizing cylinder 18, the flow rate is tested through the pressure difference, and at this time, the filter speed of the filter paper board between the blocking shaft 36 and the mounting groove 37 is tested.
