Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, specifically a filter sealing performance testing device. Background Technology

[0002] An air filter is a component that uses filter paper to filter impurities or gases. As an engine component, during filter manufacturing, it's crucial to ensure the filter housing is sealed and leak-proof, requiring the filter to undergo rigorous testing.

[0003] However, existing testing equipment generally suffers from the following problems: First, the reliability of the seal needs improvement, as most rely on manual pressing for sealing, and uneven pressing pressure can easily lead to "false seals," affecting the accuracy of the test results; second, testing efficiency is limited, lacking automation and visualization methods, often requiring repeated removal and inspection, which reduces testing efficiency; third, operation is not convenient enough, as manual operation is time-consuming and labor-intensive, making it difficult to meet the needs of large-scale production. Therefore, this utility model aims to solve the above problems by providing a filter sealing performance testing device that can achieve automated sealing, uniform and controllable pressure, and has a visual observation function. Utility Model Content

[0004] The purpose of this invention is to provide a filter sealing performance testing device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a filter sealing performance testing device, comprising a housing, support columns, and a connecting plate, characterized in that: support columns are installed on both sides above the housing, a connecting plate is installed above the support columns, and an installation device is installed on the outer side of the connecting plate;

[0006] The installation device includes a main body, branch pipes, and connecting pipes. A branch pipe is installed above the connecting plate, and the main body is installed at the middle position above the branch pipe. Multiple connecting pipes are installed on both sides below the branch pipe. The outer wall of the connecting pipe is fixed to the inner side of the connecting plate. A sliding pipe is installed inside the connecting pipe. The lower part of the sliding pipe passes through a first fixing groove and connects to the upper part of the pressing plate. The first fixing groove is installed at the bottom of the connecting pipe.

[0007] Preferably, the inside of the pressing plate and the inner side of the box are provided with multiple grooves. A second fixing groove is installed in the middle position of the outer side of the groove. A sealing gasket is installed on the inner side of the groove. An air outlet pipe is provided below the second fixing groove. The upper part of the air outlet pipe is connected to the inner wall of the box.

[0008] Preferably, electric cylinders are installed on both sides above the pressing plate, and the upper part of the electric cylinders is connected to the bottom of the connecting plate.

[0009] Preferably, the groove on the inner side of the pressing plate and the groove on the inner side of the box are arranged opposite to each other, and the middle positions of the multiple grooves above are on the same horizontal line.

[0010] Preferably, the second fixing groove below is connected to the air outlet pipe and the groove below.

[0011] Preferably, the second fixing groove above is connected to the air outlet pipe and the upper groove.

[0012] Preferably, the electric cylinders are arranged perpendicularly to the pressing plate and the connecting plate, and the electric cylinders are arranged parallel to the connecting pipe.

[0013] Preferably, the connecting pipe and the sliding pipe are slidably connected.

[0014] Preferably, the interiors of the main tube, branch tube, connecting tube, sliding tube, upper second fixing groove, and upper groove are interconnected.

[0015] Preferably, the electric cylinders on both sides operate synchronously, and the sides of the housing are made of glass.

[0016] Compared with existing technologies, the beneficial effects of this utility model are:

[0017] By setting up the main body, branch pipes and connecting pipes, water is injected into the interior through the lower groove, the lower second fixing groove and the air outlet pipe. Then, the filter to be tested is placed on the groove on the inside of the box. The bottom is initially sealed by the sealing gasket. The electric cylinder is started to push the pressing plate to slide down along the connecting pipe. The sliding pipe moves with the pressing plate to keep the gas passage open until the groove under the pressing plate completely covers the top of the filter. At this time, the upper and lower sealing gaskets completely seal both ends of the filter.

[0018] Start the gas delivery equipment connected to the outside of the main body, and input compressed gas into the system through the main body. The gas is distributed to each connecting pipe through the branch base, and then enters the groove of the pressing plate through the sliding pipe, and finally is injected into the filter. If the filter is well sealed, there is no gas leakage inside and no bubbles are generated in the water inside the box. If there is a leak in the filter, the internal gas enters the water through the leak point and will generate continuous bubbles at the leak location. The source of the bubbles can be directly observed through the glass box. The detection process is simplified and no parameters need to be set. New workers can quickly master it and reduce training costs.

[0019] After the test is completed, the electric cylinder retracts, pulling the pressing plate upward to remove the filter, thus completing the cycle. Attached Figure Description

The main body 401 is installed at the middle position above the branch pipe 402. Multiple connecting pipes 403 are installed on both sides below the branch pipe 402. The outer wall of the connecting pipe 403 is fixed to the inner side of the connecting plate 3. A sliding pipe 404 is installed inside the connecting pipe 403. The lower part of the sliding pipe 404 passes through the first fixing groove 405 and is connected to the upper part of the pressing plate 406. The first fixing groove 405 is installed at the bottom of the connecting pipe 403.

[0031] Multiple grooves 408 are provided inside the pressing plate 406 and inside the box 1. A second fixing groove 407 is installed in the middle position of the outer side of the groove 408. A sealing gasket 409 is installed inside the groove 408. An air outlet pipe 410 is provided below the second fixing groove 407.

[0040] Working principle:

[0041] First, water is injected into the interior of 1 through the lower groove 408, the lower second fixing groove 407 and the air outlet pipe 410. Then, the filter to be tested 5 is placed on the groove 408 inside the box 1. The bottom is initially sealed by the sealing gasket 409. The electric cylinder 411 is started to push the pressing plate 406 to slide down along the connecting pipe 403.

If the filter 5 is well sealed, there is no gas leakage inside, and no bubbles are generated in the water in the box 1. If there is a leak in the filter 5, the internal gas enters the water through the leak point and will generate continuous bubbles at the leak point. The source of the bubbles can be directly observed through the glass box 1. The detection process is simplified and no parameters need to be set. New workers can quickly master it and reduce training costs.

[0043] After the test is completed, the electric cylinder 411 retracts, pulling the pressing plate 406 upward, removing the filter 5, and completing the cycle.
