Description

Technical Field

[0001] This utility model relates to the technical field of filter testing equipment, and in particular to filter assembly and leak detection production equipment. Background Technology

[0002] Filter leak detection equipment is a key tool used to detect whether there are leaks in filters, mainly to ensure the sealing and structural integrity of filters.

[0003] Common filter leak detection equipment primarily uses water testing. The filter is submerged underwater and pressurized internally. By observing whether air bubbles appear on the water surface under pressure and using relevant instruments, key indicators such as the filter's sealing performance, pressure resistance, and oil-water separation efficiency can be determined.

[0004] Most filter water testing equipment uses single-sided feeding for testing, which does not ensure airtightness accuracy and usually takes a certain amount of time. Single-sided feeding testing wastes a lot of time. At the same time, the fixed height clamping plate is inconvenient for loading and unloading, reducing work efficiency. Therefore, a filter assembly leak testing production equipment is proposed to solve the above problems. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides a filter assembly and leak detection production equipment, which aims to improve the problem that existing filter leak detection equipment cannot perform rapid loading and unloading for testing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] The filter assembly and leak detection production equipment includes a structural frame and a testing box. A movable component is installed inside the structural frame, and a housing is installed outside the movable component. A rotating component is installed inside the housing. A fixed plate is connected to the front of the rotating component via a rotating shaft. Clamping components are installed on both sides of the fixed plate. A water tank is fixedly connected to the bottom of the structural frame, and the testing box is slidably connected inside the water tank.

[0008] The rotating assembly includes a first bevel gear, which is fixedly connected to the end of the rotating shaft. A second bevel gear is rotatably connected inside the housing, and the second bevel gear meshes with the first bevel gear.

[0016] The top of the structural frame is fixedly connected to a second motor, and the end of the threaded rod is fixedly connected to the output end of the second motor.

[0017] As a further description of the above technical solution:

[0018] A slider is fixedly connected to the outside of the outer shell, and a groove is provided inside the structural frame, with the slider slidably connected inside the groove.

[0019] As a further description of the above technical solution: a detection port is installed on the outside of the detection box, a baffle is fixedly connected to the bottom of the detection box, and a bracket is fixedly connected to the outside of the detection box.

[0020] As a further description of the above technical solution:

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, a motor drives a bevel gear to rotate, which in turn drives the meshing bevel gear to rotate, causing the fixed plate to rotate. This allows for changing the up and down direction of the fixed plate, enabling rapid loading and unloading and improving production efficiency.

[0024] In this invention, a telescopic air pump on the upper side of the fixed plate is driven to open the clamping plate. The filter is placed in the middle of the clamping plate and supported by a telescopic cloth. Then, the telescopic air pump is driven to clamp the filter and drive the rotating assembly to rotate the filter at the upper end of the fixed plate to the lower end. Then, the telescopic air pump is released, and the filter is supported by the support plate. The filter port is clamped and tightened at the detection port. The filter is pressurized and leak-tested through the air intake structure inside the detection box, achieving rapid and continuous testing and improving production efficiency.

[0025] In this invention, the threaded rod is driven to rotate by starting the motor. The rotating threaded rod causes the threaded housing to move up and down, providing space for the rotation of the fixed plate and enabling rapid loading and unloading. Attached Figure Description

Detailed Implementation

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Reference Figures 1-3This utility model provides an embodiment of a filter assembly leak testing production equipment, including a structural frame 16 and a testing box 4. The testing box 4 contains a pressurizing air pump, air pipes, buckles, and other structural equipment to perform airtightness pressurization testing on the filter. This is existing technology and will not be described in detail here. The structural frame 16 has a moving component installed inside, and a housing 11 is installed on the outside of the moving component. The housing 11 protects the internal mechanical structure and makes the structure more stable. A rotating component is installed inside the housing 11. A fixed plate 6 is connected to the front of the rotating component through a rotating shaft 10. The fixed plate 6 rotates through the rotating component. Clamping components are installed on both sides of the fixing plate 6. The clamping components clamp the filter for loading and unloading. A water tank 1 is fixedly connected to the bottom of the structural frame 16. The water tank 1 performs airtightness testing on the pressurized filter. By observing the bubbles generated and the internal pressure of the filter immersed in the water tank 1, the leak detection is completed. A test port 5 is installed on the outside of the test box 4. The test port 5 fixes the filter. The test box 4 performs airtightness pressurization testing on the filter through the test port 5. The test port 5 is a necessary structure in the existing filter testing equipment and is prior art. It is not an improvement of this application and will not be described in detail here. A baffle 2 is fixedly connected to the bottom of the testing box 4. The baffle 2 prevents the filter from falling into the water tank 1 if the testing port 5 is not clamped tightly. At the same time, the baffle 2 with leakage holes allows water to leak through the holes. A bracket 3 is fixedly connected to the outside of the testing box 4. The bracket 3 supports the filter and ensures the stability of the filter during testing. The testing box 4 is slidably connected to the inside of the water tank 1. The filter placed in the bracket 3 is clamped through the testing port 5. Then, the testing box 4 moves the bracket 3 and the baffle 2 downward, and water seeps out through the baffle 2 to completely immerse the filter. At the same time, the testing box 4 pressurizes the gas inside the filter. The airtightness test result of the filter is confirmed by observing whether there are air bubbles and checking the instruments. The rotating component includes a bevel gear 12, which is fixedly connected to the end of the rotating shaft 10. The rotating bevel gear 12 drives the rotating shaft 10 to rotate. The inner part of the outer casing 11 is rotatably connected to the bevel gear 13, which meshes with the bevel gear 12. The outer side of the outer casing 11 is fixedly connected to the motor 14. The end of the bevel gear 13 is fixedly connected to the output end of the motor 14. When the motor 14 is started, it drives the bevel gear 13 to rotate. The rotating bevel gear 13 drives the meshing bevel gear 12 to rotate, causing the rotating shaft 10 to rotate. This causes the fixed plate 6, which is fixedly connected to the rotating shaft 10, to rotate. The fixed plate 6 contains the control pipeline of the telescopic air pump 7 and the connection lines of the existing equipment structure such as sensors. The motor 14 only drives the fixed plate 6 to rotate reciprocally, that is, rotates half a turn clockwise and then half a turn counterclockwise, and so on, to prevent the internal pipes from getting tangled.

[0037] Reference Figures 1-3The moving component includes a threaded rod 15, which is rotatably connected to the inside of the structural frame 16. The outer shell 11 is threadedly connected to the outside of the threaded rod 15. When the threaded rod 15 rotates, the outer shell 11 moves up and down on the threaded rod 15. A second motor 19 is fixedly connected to the top of the structural frame 16. The end of the threaded rod 15 is fixedly connected to the output end of the second motor 19. When the second motor 19 is started, it drives the threaded rod 15 to rotate. The rotating threaded rod 15 drives the outer shell 11 to move up and down, so that the fixed plate 6 connected to it moves up and down with the outer shell 11, leaving space for the fixed plate 6 to rotate. A slider 17 is fixedly connected to the outside of the outer shell 11. The slider 17 fixed to the outside of the outer shell 11 moves up and down with the outer shell 11 outside the threaded rod 15. A groove 18 is opened inside the structural frame 16. The slider 17 is slidably connected inside the groove 18. The slider 17 sliding in the groove 18 makes the outer shell 11 slide more stably on the threaded rod 15.

[0038] Reference Figures 1-3 The clamping assembly includes a fixed plate 6, with a telescopic air pump 7 fixedly connected to one end of the fixed plate 6. Clamping plates 8 are fixedly connected to both ends of the telescopic air pump 7. The telescopic air pump 7 extends and retracts the clamping plates 8 to clamp and release the filter. A telescopic cloth 9 is fixedly connected between the clamping plates 8. When the telescopic air pump 7 at the upper end of the fixed plate 6 is activated and extended, the clamping plates 8 extend and stretch the telescopic cloth 9, placing the filter on the telescopic cloth 9. The telescopic air pump 7 is then controlled to retract, causing the clamping plates 8 to clamp the filter. Then, the rotating assembly is activated, causing the fixed plate 6 to rotate, moving the filter from the upper end to the lower end. Finally, the telescopic air pump 7 is activated to extend. The filter is placed on the bracket 3 and then clamped by the test port 5 for testing. An air outlet 20 is installed on one side of the upper structural frame 16. The air outlet 20 is connected to an external air source through a pipe. The air from the external air source is blown out from the air outlet 20. The external air source can be, but is not limited to, an air compressor, which is existing technology and will not be described in detail here. An electric heating wire 21 is installed inside the structural frame 16. The electric heating wire 21 heats the incoming air and then blows it out from the air outlet 20, thereby drying the moisture on the outside of the filter after testing, reducing the time for subsequent reprocessing and improving work efficiency.

[0039] Working principle: First, start the telescopic air pump 7 at the top of the fixed plate 6 to extend, causing the clamping plate 8 to open and the telescopic cloth 9 to unfold. Place the filter on the telescopic cloth 9, and control the telescopic air pump 7 to retract, causing the clamping plate 8 to clamp the filter. Then, start the motor 14 to drive the bevel gear 13 to rotate. The rotating bevel gear 13 drives the meshing bevel gear 12 to rotate, causing the rotating shaft 10 to rotate. This causes the fixed plate 6, which is fixedly connected to the rotating shaft 10, to rotate, rotating the installed filter from the top to the bottom. Then, start the motor 2 19 to drive the threaded rod 15 to rotate. The rotating threaded rod 15 drives the outer shell 11 to move downward, causing the fixed plate 6 to move downward with the outer shell 11. Then, start the telescopic air pump 7 to extend, and the clamping plate 8 will loosen, placing the filter on the bracket 3. The filter placed in the bracket 3 is clamped through the test port 5. Then, the test box 4 moves the bracket 3 and the baffle 2 downwards, and water seeps out through the baffle 2 to completely soak the filter. At the same time, the test box 4 pressurizes the gas inside the filter. By observing whether there are bubbles and checking the instruments, the airtightness test results of the filter are confirmed. Meanwhile, the air from the external air source is heated by the heating wire 21 and blown out from the air outlet 20 to dry the moisture on the outside of the filter that has been tested and moved from the bottom to the top. Then, the telescopic air pump 7 at the top of the fixing plate 6 is started to extend, so that the clamping plate 8 is released. The telescopic cloth 9 lifts the filter at the top, and the completed filter is taken out and the untested filter is placed in. The telescopic air pump 7 is restarted to telescopically clamp and complete the leak detection work.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
