[0002] As a commonly used material in the field of industrial filtration, the filtration rate performance of filter paperboard is crucial. In many industrial production processes involving solid-liquid separation, such as chemical, pharmaceutical, food and beverage, environmental protection and other industries, efficient filtration equipment is needed to ensure product quality, improve production efficiency, and achieve resource recovery and environmental protection. Traditional filter paperboard filtration rate detection methods have problems such as complex detection process, long detection time, and poor accuracy, which cannot meet the needs of rapidly developing industrial production for efficient detection. With the continuous expansion of industrial production scale and the increasing requirements for product quality, the development of a fast, accurate and easy-to-operate filter paperboard filtration rate detection method has become a key issue that needs to be urgently solved in the industry. This is of great significance to improving the technical level and economic benefits of the entire filtration industry.

[0003] In the prior art, the filtration rate detection is only performed on the filter paperboard as a whole, but the local position of the filter paperboard cannot be detected in place, which is not conducive to detecting whether the filtration rate of each position of the filter paperboard is uniform. Summary of the invention

[0004] In view of the above technical problems, the present invention discloses a filter paperboard filter speed detection device, comprising a bottom mounting plate, two detection components are mounted on the bottom mounting plate and are symmetrically arranged, one detection component is slidably connected to the bottom mounting plate, and the other detection component is fixedly connected to the bottom mounting plate, and a filter paperboard to be detected is placed between the two detection components, and a bottom electric cylinder is fixedly mounted on the bottom mounting plate, and the bottom electric cylinder is used to drive the detection component slidably connected to the bottom mounting plate to move, so as to clamp the filter paperboard; The detection assembly includes a second support plate, on which a fixed cylinder is fixedly mounted, a mounting groove is arranged at the first end of the fixed cylinder, and the mounting grooves of the two detection assemblies are used to clamp the filter paper board, and a rotating cylinder is rotatably mounted at the second end of the fixed cylinder, a center ring is arranged in the rotating cylinder, a pressurizing cylinder is arranged on the center ring, the pressurizing cylinder and the rotating cylinder are eccentrically arranged, and the pressurizing cylinders in the two detection assemblies jointly support the filter paper board to perform local detection of the filter paper board. Through the above technical scheme, water filtration rate can be detected by passing water and pressurizing in the rotating cylinders on both sides of the filter paper board, and local filtration rate can be detected by passing water and pressurizing in the pressurizing cylinders on both sides. Different structures can be used to detect different positions of the filter paper board, so as to ensure the filtration rate of the filter paper board, and at the same time, whether the filtration rate of each position of the filter paper board is uniform can be detected, so as to ensure the quality of the filter paper board.

[0007] Furthermore, a squeezing spring is fixedly mounted on the sliding rod, a blocking ring is fixedly mounted on the rotating cylinder, the blocking ring is fixedly connected to the squeezing spring, and in a natural state, the squeezing spring presses against the sliding rod, driving the pressure cylinder on the center ring to press against the filter paper board.

[0008] Furthermore, a toggle plate is fixedly mounted on the rotating cylinder, and when the extrusion spring is compressed to the limit position, the protruding block contacts the toggle plate, and the protruding block drives the toggle plate and the rotating cylinder to rotate. Through the above technical solution, when performing local detection, the pressure cylinder needs to switch positions, and the rotation of the connecting ring can first drive the pressure cylinder to leave the filter paper board and then change the position, and finally clamp the filter paper board again, thus avoiding direct sliding on the filter paper board, reducing damage to the filter paper board, and improving the accuracy of detection.

[0009] Furthermore, the detection assembly also includes a support plate 1 arranged on the top of the bottom mounting plate, a matching ring is fixedly mounted on the support plate 1, the rotating cylinder is rotatably connected to the inner ring wall of the matching ring, a plurality of positioning holes are arranged on the side of the matching ring, a positioning pin is slidably mounted on the blocking ring, a positioning spring is fixedly mounted between the positioning pin and the blocking ring, and the positioning pin is inserted into the positioning hole. Through the above technical solution, the positioning pin cooperates with the positioning hole to allow the rotating cylinder to remain stationary when subjected to a small force, and starts to move after the protruding block contacts the toggle plate, which not only ensures the stability of the position, but also ensures that the rotation can be realized, thereby improving the operation efficiency of the machine.

The interior of the water containing ring is hollow, and a sealing disk with a central circular hole is rotatably installed on the water containing ring. The sealing disk is slidably connected to the surface of the pressurizing cylinder, and a packaging cylinder is installed in the center of the water containing ring. An intermediate cylinder is installed concentrically with the packaging cylinder. The surface of the intermediate cylinder is fit with the inner wall of the central circular hole of the sealing disk, and a gap is left between the intermediate cylinder and the cylinder wall of the packaging cylinder. A limit disk is fixedly installed on one end of the pressurizing cylinder, and the limit disk moves in the water containing ring.

[0011] Further, a support rod is fixedly installed on the first support plate. A water pipe path is arranged inside the support rod. The upper end of the support rod is sleeved on the middle cylinder. The water pipe path inside the support rod is communicated with the inside of the encapsulation cylinder. Water is passed through the water pipe path, and the water flows into the water storage ring through the gap between the encapsulation cylinder and the middle cylinder.

[0012] Further, a switching electric cylinder is fixedly installed on the support rod. A central moving shaft is fixedly installed on the telescopic arm of the switching electric cylinder.

[0014] Step 3: Overall detection, add water to one of the detection components, and the other detection component is used for water discharge operation to test the flow rate.

[0015] Step 4: Local detection, let the pressurization cylinders of the two detection components press against the filter paperboard, pass water and pressurize into the pressurization cylinders, apply different pressures on both sides of the filter paperboard for flow rate detection, and let the pressurization cylinders rotate around the axis of the fixed cylinder to detect different positions.

[0016] Step 5: Edge detection, let the plugging shafts in the two detection components press against the filter paperboard, then add water between the plugging shaft and the installation groove through the pressurization cylinder, and test the flow rate through the pressure difference. At this time, the filtration rate of the filter paperboard between the plugging shaft and the installation groove is detected.

[0017] The beneficial effects of the present invention compared with the prior art are: (1) Through the above technical solution, water can be passed and pressurized in the rotating cylinders on both sides of the filter paperboard to detect the filtration rate of water, and water can be passed and pressurized in the pressurization cylinders on both sides to detect the local filtration rate.

[0018] (2) With the above technical solution, when performing local detection, the pressure cylinder needs to switch its position. By rotating the connecting ring, the connecting ring can first drive the pressure cylinder to leave the filter paper board and then change its position, and finally clamp the filter paper board again. This avoids direct sliding on the filter paper board, reduces damage to the filter paper board, and improves the accuracy of detection.

[0019] (3) Through the above technical solution, the positioning pin and the positioning hole cooperate to allow the rotating cylinder to remain stationary when subjected to a small force, and start to move after the protruding block contacts the toggle piece, which not only ensures the stability of the position, but also ensures that rotation can be achieved, thereby improving the operating efficiency of the machine.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] like Figures 1 - 10As shown in the figure, a device for detecting the filtration rate of filter paperboard includes a bottom mounting plate 1. Two detection components are installed on the bottom mounting plate 1 and are symmetrically arranged. One of the detection components is slidably connected to the bottom mounting plate 1, and the other detection component is fixedly connected to the bottom mounting plate 1. The filter paperboard to be detected is placed between the two detection components. A bottom electric cylinder 2 is fixedly installed on the bottom mounting plate 1. The bottom electric cylinder 2 is used to drive the detection component slidably connected to the bottom mounting plate 1 to move to clamp the filter paperboard. The detection component controls an appropriate pressure and detects the water permeability through the pressure difference. Three detection modes are set in the detection component. The first is the overall detection, which detects the whole. The second is the local detection. The pressurizing cylinder 18 is set at an eccentric position of the rotating cylinder 26 and rotates around the axis of the rotating cylinder 26. Water is passed through the pressurizing cylinder 18 for detection. The third is the edge detection. The middle area of the filter paperboard is blocked, and water is allowed to pass through the edge position of the filter paperboard for detection. Water is passed through and pressurized in the rotating cylinders 26 on both sides of the filter paperboard to facilitate the detection of the filtration rate of the whole and the edge of the filter paperboard. Water is passed through and pressurized in the pressurizing cylinders 18 on both sides to detect the local filtration rate. Different positions of the filter paperboard are detected through different structures, which can ensure the filtration rate of the filter paperboard and at the same time detect whether the filtration rate of each position of the filter paperboard is uniform, and can ensure the quality of the filter paperboard. A flowmeter is set at the water outlet position to measure the water flow per unit time. One of the two detection components intakes water and the other discharges water, but the internal pressure needs to be ensured. The flowmeter is set at the water pipe 24 in the detection component responsible for discharging water.

[0034] In this embodiment, the detection assembly includes a second support plate 4. The telescopic arm of the bottom cylinder 2 is fixedly installed on the bottom of the second support plate 4. One of the second support plates 4 is slidably connected to the bottom mounting plate 1. The bottom cylinder 2 drives the second support plate 4 to slide on the bottom mounting plate 1. Only one of the two detection assemblies can slide. Therefore, the telescopic arm of the bottom cylinder 2 is only connected to the second support plate 4 that is slidably connected to the bottom mounting plate 1. The other second support plate 4 is fixedly connected to the bottom mounting plate 1. A fixed cylinder 27 is fixedly installed on the second support plate 4. An installation groove 37 is provided at the first end of the fixed cylinder 27 (the end in contact with the filter paper is the first end). The installation grooves 37 of the two detection assemblies are used to clamp the filter paper. By driving the second support plate 4 to move with the bottom cylinder 2, a gap is exposed between the two fixed cylinders 27. The filter paper is placed on the installation groove 37, and the second support plate 4 is moved in the reverse direction so that the two fixed cylinders 27 clamp the filter paper through the installation groove 37. A rotating cylinder 26 is rotatably installed at the second end of the fixed cylinder 27. A central ring 17 is installed in the rotating cylinder 26. A pressurizing cylinder 18 is rotatably installed on the central ring 17. The pressurizing cylinder 18 is eccentrically arranged with respect to the rotating cylinder 26. Four mating holes 31 are provided on the rotating cylinder 26. The number can also be other values in other embodiments. A sliding rod is fixedly installed on the central ring 17, and four sliding rods are also provided. The sliding rods slide in the mating holes 31. The central ring 17 is coaxial with the rotating cylinder 26. A sliding rod 14 and a blocking plate 16 are fixedly installed on the sliding rod. The blocking plate 16 is located inside the rotating cylinder 26, and the sliding rod 14 is located outside the rotating cylinder 26. Since the sliding rod needs to slide along the inner wall of the mating hole 31, the mating hole 31 should be arranged in a long strip shape. However, the inside of the rotating cylinder 26 and the fixed cylinder 27 needs to be kept sealed. Therefore, a blocking plate 16 is provided inside the rotating cylinder 26. The blocking plate 16 can slide inside the rotating cylinder 26, but always completely covers the mating hole 31 and maintains the seal. The pressurizing cylinders 18 in the two detection assemblies jointly press against the filter paper to perform local detection on the filter paper.

[0035] In this embodiment, a large toothed ring 11 is rotatably mounted on the fixed cylinder 27, a connecting ring 28 is fixedly mounted on the large toothed ring 11, the connecting ring 28 and the large toothed ring 11 are a whole (hereinafter the connecting ring 28 and the large toothed ring 11 are regarded as the same part), one side of which is cut into a gear shape as the large toothed ring 11, a protruding block 12 is fixedly mounted on the connecting ring 28, a spherical connecting rod 13 is mounted on the protruding block 12 through a ball hinge, the spherical connecting rod 13 and the sliding rod 14 are also connected through a ball hinge, a rotating driving mechanism is provided on the surface of the fixed cylinder 27, the rotating driving mechanism is used to drive the large toothed ring 11 to rotate, rotating the large toothed ring 11 can drive the sliding rod 14 to slide through the spherical connecting rod 13, the sliding of the sliding rod 14 can drive the center ring 17 to slide, and the center ring 17 It can drive the pressure cylinder 18 to slide, and the pressure cylinder 18 can support the filter paper board or leave the filter paper board. In this embodiment, the sliding rod 14 is fixedly provided with an extrusion spring 15, and the rotating cylinder 26 is fixedly provided with a blocking ring 29, and the blocking ring 29 is fixedly connected to the extrusion spring 15. In the natural state, the extrusion spring 15 supports the sliding rod 14, driving the pressure cylinder 18 on the center ring 17 to press the filter paper board tightly. The connecting ring 28 drives the sliding rod 14 to move through the spherical connecting rod 13 to squeeze the extrusion spring 15, and the pressure cylinder 18 on the center ring 17 leaves the filter paper board. If the connecting ring 28 is reversed, it can drive the sliding rod 14 to slide in the opposite direction, and the extrusion spring 15 returns to its original state to assist in exerting force, driving the pressure cylinder 18 on the center ring 17 to press the filter paper board tightly.

[0036] In this embodiment, a toggle piece 25 is fixedly mounted on the rotating cylinder 26. When the extrusion spring 15 is compressed to the limit position, the protruding block 12 contacts the toggle piece 25, driving the toggle piece 25 and the rotating cylinder 26 to rotate. That is to say, the connecting ring 28 rotates through the spherical connecting rod 13 to drive the sliding rod 14 to move, and finally drives the pressurizing cylinder 18 away from the filter paper board. When the sliding rod 14 reaches the limit position, the connecting ring 28 continues to rotate and pushes the toggle piece 25 through the protruding block 12. The toggle piece 25 drives the rotating cylinder 26 to rotate. The rotation of the rotating cylinder 26 drives the sliding rod 14, the center ring 17 and the pressurizing cylinder 18 to rotate through the matching hole 31. When the connecting ring 28 is reset, the pressurizing cylinder 18 continues to press against the filter paper board, that is, in the initial position, the pressurizing cylinders 18 of the two detection assemblies press against the filter paper board, and then the pressurizing cylinder 18 leaves the filter paper board, the pressurizing cylinder 18 rotates, and finally the pressurizing cylinder 18 presses against the filter paper board, thereby completing the change of the detection position. Through the above technical solution, when performing local detection, the pressurizing cylinder 18 needs to switch its position, and through the rotation of the connecting ring 28, the pressurizing cylinder 18 can first leave the filter paper board and then change its position, and finally clamp the filter paper board again, thus avoiding direct sliding on the filter paper board, reducing damage to the filter paper board, and improving the accuracy of detection.

[0037] The cam 32 is engaged with the locking cam 36 and the locking cam 37 is engaged with the locking cam 38. The locking cam 38 is engaged with the locking cam 38 in a manner similar to that of the locking cam 38. The cam 38 is engaged with the locking cam 38 in a manner similar to that of the locking cam 38. The cooperation between the positioning pin 32 and the positioning hole 35 can keep the rotating cylinder 26 stationary when subjected to a small force, and start to move after the protruding block 12 contacts the toggle piece 25, which not only ensures the stability of the position, but also ensures that rotation can be achieved, thereby improving the operating efficiency of the machine. It should be noted that the support plate 3 on the detection component that is controlled to move by the bottom electric cylinder 2 is slidably connected to the top of the bottom mounting plate 1, and the support plate 3 on the other detection component is fixedly connected to the top of the bottom mounting plate 1.

[0038] In this embodiment, an end cover 8 is rotatably mounted on one side of the rotating cylinder 26, and the edge of the end cover 8 is fixed to the support plate 3 by fixing bolts 34 (such as Figure 2 ), a through hole is set in the middle position of the end cover 8, a water containing ring 21 is fixedly installed on the end cover 8, the water containing ring 21 is located in the rotating cylinder 26, the interior of the water containing ring 21 is hollow, a central circular hole sealing disk 20 is rotatably installed on the water containing ring 21, the sealing disk 20 is slidably connected with the surface of the pressurizing cylinder 18, the pressurizing cylinder 18 and the sealing disk 20 are eccentrically set, specifically, a circular hole is set at the eccentric position of the sealing disk 20, when the center ring 17 drives the pressurizing cylinder 18 to slide in the circular hole, the pressurizing cylinder 18 is used to realize For the pressing and separation of the filter paper board, a packaging cylinder 22 is installed in the center of the water ring 21, and an intermediate cylinder 23 is installed in the concentric position of the packaging cylinder 22. The surface of the intermediate cylinder 23 fits the inner wall of the central circular hole of the plugging disk 20. There is a gap between the packaging cylinder 22 and the plugging disk 20, and there is a gap between the intermediate cylinder 23 and the cylinder wall of the packaging cylinder 22. The diameter of the intermediate cylinder 23 is smaller than that of the packaging cylinder 22. A limit plate 19 is fixedly installed at one end of the pressurizing cylinder 18, and the limit plate 19 moves in the water ring 21. When the pressurizing cylinder 18 presses against the filter paper board, the limit plate 19 is tightly against the plugging disk 20 for sealing.

[0039] In this embodiment, a support rod 5 is fixedly mounted on the support plate 1 3, a water pipe 24 is arranged inside the support rod 5, the upper end of the support rod 5 is sleeved on the intermediate tube 23, the water pipe 24 inside the support rod 5 is connected with the inside of the packaging tube 22, water flows through the water pipe 24, and the water flows into the water containing ring 21 through the packaging tube 22 and the intermediate tube 23. A switching electric cylinder 6 is fixedly mounted on the support rod 5, a central moving shaft 7 is fixedly mounted on the telescopic arm of the switching electric cylinder 6, and a blocking shaft 36 is fixedly mounted on the central moving shaft 7. The central moving shaft 7 is located inside the intermediate cylinder 23 and is coaxially connected. Water flows into the water containing ring 21 through the gap between the water pipe 24, the packaging cylinder 22 and the intermediate cylinder 23, and finally enters the pressurizing cylinder 18. The cooperation between the matching ring 30 and the pressurizing cylinder 18 can ensure the movement of the pressurizing cylinder 18 without interference, and is sealed by the limit plate 19 to ensure the internal pressure of the pressurizing cylinder 18, improve the detection accuracy, and improve the smoothness of the operation and the detection efficiency of the present invention.

[0040] Working principle: The filter paperboard is cut into round shapes for testing, such as Figure 1 As shown, the bottom electric cylinder 2 is started, and the bottom electric cylinder 2 drives one of the support plates 2 4 to move, and the fixing cylinders 27 in the two support plates 2 4 move away from each other, and the filter paper board is placed on the installation groove 37 ( Figure 2 ), and then drive the fixed cylinder 27 in the reverse direction, so that the two fixed cylinders 27 clamp the filter paper board, first perform an overall inspection, and pass water into the support rod 5 (the shape of the support rod 5 is as shown in FIG. Figure 9 , Figure 10 ) Water passes through the water pipe 24 into the space between the packaging cylinder 22 and the middle cylinder 23, 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. 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, so that the pressures in the two detection components are inconsistent, that is, the pressures on both sides of the filter paper board are inconsistent. Subsequently, water is injected into the rotating cylinder 26 in one of the detection components, and water flows out of the other detection component, thereby testing the filtration rate.

[0041] The rotary drive mechanism includes a motor 9 fixedly mounted on a fixed cylinder 27, a gear 10 fixedly mounted on the rotating shaft of the motor 9, the gear 10 meshes with the large gear ring 11, and the rotation of the gear 10 drives the connecting ring 28 integrated with the large gear ring 11 to rotate, 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 away from the filter paper board. When doing the overall inspection, it is in this state. When doing the local inspection, continue to rotate the connecting ring 28, the protruding block 12 on the connecting ring 28 will contact the toggle piece 25, and thereby drive the rotating cylinder 26 to rotate (such as Figure 6), before the protruding block 12 contacts with the toggle piece 25, the locating pin 32 is inserted into the locating hole 35 so that the rotating cylinder 26 does not rotate. After the contact, the rotating cylinder 26 will drive the locating pin 32 to leave the locating hole 35, and the locating pin 32 is inserted into other locating holes 35. At this time, the rotating cylinder 26 will also drive the pressurizing cylinder 18 to rotate around the axis of the rotating cylinder 26 through the matching hole 31 and the center ring 17, thus changing the position. At this time, the connecting ring 28 is rotated in the reverse direction, and the protruding block 12 also moves in the reverse direction, driving the sliding rod 14, the center ring 17, and the pressurizing cylinder 18 to move in the reverse direction. With the assistance of the extrusion spring 15, the pressurizing cylinder 18 is close to the filter paper board. At this time, by filling the pressurizing cylinder 18 with water and pressurizing it, the pressurizing cylinders 18 in the two detection components are positioned relative to each other and the filter paper board is clamped, so that the local position can be detected. After the detection is completed, continuing to start the connecting ring 28 can make the pressurizing cylinder 18 leave the filter paper board, and then rotate, and finally close to the filter paper board to complete the position change.

[0042] Edge detection, start the switching electric cylinder 6, the switching electric cylinder 6 drives the central moving shaft 7 to move, 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 middle cylinder 23, and the blocking shafts 36 in the two detection components press the filter paper board from both sides. At this time, let the pressurizing cylinder 18 be in a position away from the filter paper board, and then inject water 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.

[0043] 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 enters the water holding ring 21 through the gap between the intermediate cylinder 23 and the packaging barrel 22, 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. 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 the rotating cylinder 26 is filled with water for detection through the pressurized cylinder 18. During the local detection, the pressurized cylinder 18 supports the filter paper board and water is passed through the detection. During the edge detection, the sealing shaft 36 supports 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.

[0044] A method for detecting the filtration rate of a filter paperboard comprises the following steps: Step 1: Installation: clamp the filter paper between the two test components and use the metal grid as support; Step 2: Prepare for testing, fill the rotating cylinder 26 and the fixed cylinder 27 with water and pressurize them, wait for the filter paper to be completely soaked, and then pressurize them again to make the pressure on both sides of the filter paper different.

[0045] Step 3: Overall detection. Add water to one of the detection components, and the other detection component is used for water discharge operation to test the flow rate.

[0046] Step 4: Local detection. Let the pressure cylinders 18 of the two detection components press against the filter paper board, pass water into the pressure cylinders 18 for pressurization, apply different pressures on both sides of the filter paper board for flow rate detection, and let the pressure cylinders 18 rotate around the axis of the fixed cylinder 27 to detect different positions.

[0047] Step 5: Edge detection. Let the plugging shafts 36 in the two detection components press against the filter paper board, then add water between the plugging shafts 36 and the installation grooves 37 through the pressure cylinders 18, and test the flow rate through the pressure difference. At this time, the filtration rate of the filter paper board between the plugging shafts 36 and the installation grooves 37 is detected.
