[0002] Filter cartridge, also known as filter cartridge, metal filter mesh cartridge, mesh tube, mesh barrel, filter tube, is a commonly used filter element, widely used in industrial manufacturing, environmental protection, water treatment and other fields. In the prior art, filter hole detection is mostly done by immersing the filter cartridge in IPA, and then filling the filter tube with gas. When the tube reaches a specific pressure, bubbles form on the surface of the tube in the IPA liquid. The pressure inside the tube when the first bubble escapes can be used to determine the maximum pore size of the filter cartridge filter hole.

[0003] However, in the above-mentioned process of detecting the maximum pore size value of the filter cartridge filter holes, since it is necessary to observe the pressure inside the tube when the first bubble escapes, the inflation needs to be slow, and the filter holes of the sintered filter cartridge are micron-level, and the filter holes need to reach a specific pressure inside to have the effect of gas permeation detection. This results in a relatively long pressurization process during the detection process, affecting the detection efficiency.

[0004] Therefore, a high-efficiency filter hole detection device for sintered filter cartridge is proposed. Utility Model Content

[0026] like Figures 1 to 5 As shown, a specific embodiment of the utility model provides a sintered filter cartridge high-efficiency filter hole detection device, including a detection platform 1, a gas delivery component 2 is fixedly installed on the detection platform 1, a large throttle valve 3 and a small throttle valve 4 are arranged on the gas delivery component 2, the large throttle valve 3 and the small throttle valve 4 are connected to a U-shaped tube 5, and a gas delivery pipe 6 is fixedly connected to the U-shaped tube 5, and a filter cartridge 7 is arranged on the top of the detection platform 1; a detection component for automatically immersing the filter cartridge 7 is arranged at the bottom end of the filter cartridge 7, and by setting the detection component, when the filter hole of the filter cartridge 7 is detected, the filter cartridge 7 is automatically fixed and then the device can automatically contact and immerse the filter cartridge 7 with a solution, without manual implementation, so as to further improve the work efficiency, and the detection component includes a solution box 8 arranged on the detection platform 1, a bottom plate 9 is slidably connected in the solution box 8, and a bending plate 10 for pushing the bottom plate 9 to move is arranged on the bottom plate 9, and the solution box 8 is arranged so that a detection solution, i.e., IPA liquid, can be placed inside it and at the top of the bottom plate 9, so as to be used for the filter hole detection of the filter cartridge 7.

[0027] like Figures 1 to 5As shown, specifically, when the filter holes of the filter cartridge 7 are detected, a circular arc opening 15 adapted to the filter cartridge 7 is opened on the solution box 8, and the filter cartridge 7 is placed on the circular arc opening 15, the filter cartridge 7 is placed on the circular arc opening 15 on the solution box 8, a fixed plate 11 and a movable plate 12 are provided on the detection platform 1, a connecting pipe 13 is fixedly connected to the fixed plate 11, the movable plate 12 is slidably connected in the detection platform 1, a guide groove 17 is opened on the connecting pipe 13, a guide plate 18 is slidably connected in the guide groove 17, and a clamping plate 19 is fixedly connected to the guide plate 18, a clamping seat 20 is fixedly connected to the movable plate 12, a cylinder 21 is fixedly installed on the fixed plate 11, and an air pressure sensor 22 and The push plate 23 starts the cylinder 21 to extend it, thereby driving the air pressure sensor 22 at the end to move. The air pressure sensor 22 gradually enters the inner cavity of the filter cartridge 7 as the cylinder 21 extends, and the extension of the cylinder 21 causes the push plate 23 on the cylinder 21 to be gradually pushed until the push plate 23 moves close to the clamping plate 19 and applies thrust to it. The push plate 23 gradually pushes the clamping plate 19 to move close to the filter cartridge 7, and the guide plate 18 on the clamping plate 19 moves in the guide groove 17 to provide a limiting effect on the movement of the clamping plate 19. After the clamping plate 19 is attached to the filter cartridge 7, under the joint cooperation of the clamping seat 20, the filter cartridge 7 between the clamping plate 19 and the clamping seat 20 is clamped and tightened to maintain sealing.

[0028] like Figures 1 to 5As shown, specifically, the movable plate 12 is slidably connected in the detection platform 1, and a spring 14 is fixedly connected between the movable plate 12 and the detection platform 1, a connecting rod 16 is fixedly connected between the solution tank 8 and the movable plate 12, a limiting groove 24 is provided on the bottom plate 9, and the bending plate 10 is slidably connected in the limiting groove 24, a limiting frame 25 is fixedly installed on the detection platform 1, and the bending plate 10 is slidably connected in the limiting frame 25, a stopper 26 is fixedly connected to the bending plate 10, a long push plate 27 is fixedly connected to the clamping plate 19, and a push block 28 is fixedly connected to the long push plate 27, and matching inclined surfaces are provided on the stopper 26 and the push block 28, a tension spring 29 is fixedly connected between the bottom plate 9 and the solution tank 8, and in the above process, while the clamping plate 19 moves, the long push plate 27 is used to push the clamping plate 19 to move the solution tank 8. The plate 27 drives the push block 28 to move. When the clamping plate 19 gradually moves to fit the filter cartridge 7, the push block 28 moves to the stopper 26 and contacts it. Subsequently, when the cylinder 21 continues to work and extend, the movement of the clamping plate 19 can push the filter cartridge 7 and the solution box 8 to move. The movement of the solution box 8 enables the bending plate 10 to move in the limiting groove 24. The bending plate 10 can remain stable under the action of the limiting frame 25. The solution box 8 pushes the movable plate 12 to slide on the detection table 1 through the connecting rod 16, and the spring 14 is forced to contract and generate a reaction force. At the same time, when the cylinder 21 continues to work and extend, the clamping plate 19 will also push the push block 28 to apply pressure to the stopper 26. Since the stopper 26 and the push block 28 are provided with matching inclined surfaces, the stopper 26 is moved upward. The stopper 26 moves upward so that the bending plate 10 moves upward in the limit frame 25, and the bending plate 10 pushes the bottom plate 9 to move upward in the solution box 8, and the tension spring 29 is stretched by the force to generate a reaction force. At this time, the solution on the top of the bottom plate 9 moves with the upward movement of the bottom plate 9, so that the solution contacts the filter cartridge 7 at the top after moving upward, and then the bottom end part of the filter cartridge 7 can be soaked. Pipe holes are provided in the movable plate 12 and the clamp seat 20, and the air pipe 6 is connected to the pipe hole. During the soaking process, the air supply component 2 is started and the small throttle valve 4 is closed so that the gas passes through the large throttle valve 3 into the U-shaped tube 5 and the air pipe 6, and enters the inside of the filter cartridge 7 through the air pipe 6 until the gas pressure inside the filter cartridge 7 is about to reach the critical point. When the filter element 14 is in the air, the pressure inside the filter cartridge 7 can be determined by measuring the pressure sensor 22 which enters the filter cartridge 7. After the detection, the cylinder 21 is driven in the reverse direction so that the clamping plate 19 is no longer stressed, and the movable plate 12 pushes the solution tank 8 to move and reset under the reaction force of the spring 14. When the clamping plate 19 is not stressed, the push block 28 no longer squeezes the stopper 26, so that the bottom plate 9 can move downward and reset under the reaction force of the tension spring 29, and the bending plate 10 drives the stopper 26 to move and reset.The stopper 26 forms a reverse extrusion on the push block 28, so that the push block 28 moves in the reverse direction and resets, and the clamping plate 19 is reset under the action of the long push plate 27 manually pulled by the staff.
