[0003] For the filtering link involved in the production process, filter core filter membrane integrity test needs to be carried out regularly, and corresponding record is kept, to prove that the production process meets the specification, and to ensure product quality safety and reliability. UTILITY MODEL CONTENT

[0004] The utility model discloses a filter core filter membrane integrity test device to solve the problem in the background art.

[0005] To achieve the above object, the utility model provides the following technical scheme: a filter core filter membrane integrity test device, comprising: test box body, the bottom of test box body is installed with bearing plate, the upper of bearing plate is equipped with support plate, the bearing plate is installed with the electric telescopic link of vertical between support plate, the upper of support plate is connected with mounting plate, a plurality of electric push rods of vertical are connected on mounting plate, and the output end of these electric push rods all extends to the below of support plate and is connected with the limit plate, the lower end surface of support plate is installed with fixed plate, and the fixed plate is equipped with filter core workpiece between limit plate, and a plurality of electric push rods can conveniently clamp a plurality of filter core workpieces once, to improve work efficiency;

[0006] The upper of test box body is connected with liquid inlet pipeline, and the below of test box body is connected with liquid outlet pipeline, and the liquid outlet end of liquid inlet pipeline is equipped with drainage component;

[0007] Air inflation component is installed on the support plate;

[0008] Camera recording component is installed on the bearing plate.

[0009] Preferably, the air inflation component includes an air compressor and an air duct, the air compressor is installed on the support plate, the air duct is connected to the output end of the air compressor, and the air outlet end of the air duct is provided with a plurality of air outlets, and the plurality of output ends of the air duct extend to the lower end surface of the fixed plate and communicate with the filter core workpiece.

[0010] The lower end surface of the fixed plate and the upper end surface of the limiting plate are both provided with sealing soft pads and limiting soft pads.

[0011] Through the above technical solutions:

[0012] In use, the filter core workpiece to be tested is placed between the fixed plate and the limiting plate, and then the corresponding electric push rod is started to drive the limiting plate to move, so that the filter core workpiece is clamped between the two. The sealing soft pads and the limiting soft pads can enhance the integrity of the filter core workpiece and the equipment, ensure that there is no air leakage at the connection during subsequent inflation, and avoid adversely affecting the test results.

[0013] Through the liquid inlet pipeline, liquid is introduced into the test box, so that the liquid level in the box is higher than the test length requirement of the filter core workpiece. At the same time, the liquid can be removed by standing or gently knocking the outer wall of the test box to remove the air bubbles in the liquid.

[0014] After the filter core workpiece is clamped and the liquid is introduced, the air compressor is started to fill gas into the filter core workpiece through the air guide pipe. Then the electric telescopic rod is started to drive the supporting plate to move downward, so that the filter core workpiece below the supporting plate slowly descends and is smoothly placed into the water.

[0015] Finally, the emergence of bubbles when the filter core workpiece enters the liquid is observed. If bubbles continuously emerge from a certain fixed position of the filter core workpiece, it indicates that there may be a leakage point or poor sealing at that position, so as to judge its integrity. This test method of first introducing water flow is different from the method of first placing the filter core workpiece and then introducing water flow.

The vertical first flow guide plate cooperates with the flow guide groove to vertically guide the liquid from the liquid inlet pipe to the bottom of the tank. This vertical introduction can reduce the impact and turbulence of the liquid in the horizontal direction, thereby reducing the possibility of bubble generation. At the same time, the vertical falling of the liquid makes the path more direct, reducing the contact area with air. The horizontal second flow guide plate also cooperates with the flow guide groove to guide the liquid from the horizontal direction of the vertical first flow guide plate to the bottom of the tank. This design further disperses the liquid, making it evenly distributed at the bottom of the tank, avoiding the direct impact of the liquid on the bottom of the tank and generating bubbles. In addition, the horizontal flow guide plate can effectively reduce the flow speed of the liquid, reducing the risk of turbulence and bubble formation. During the liquid introduction process, if the liquid directly impacts the bottom of the tank or the test workpiece, bubbles are easily generated. Through the careful design of the flow guide plate, the flow path of the liquid is optimized, reducing the possibility of direct impact and thereby reducing the risk of bubble generation. The synergistic effect of the vertical and horizontal flow guide plates makes the liquid flow more stable, reducing turbulence and vortex, and ultimately reducing bubble formation.

[0019] Preferably, the recording assembly comprises a recording camera and a display screen, the recording camera is installed at the front end of the test tank, and the display screen is connected with the recording camera.

[0020] The front wall of the test tank is provided with a transparent plate body, and the recording camera can record the inside of the test tank through the transparent plate body.

[0021] Specifically, the recording camera shoots the bubble condition inside the test tank in real time, and transmits the image to the display screen for real-time display. The operator can observe the bubble generation in real time, understand the integrity of the filter core workpiece, improve the transparency and visibility of the test process, and facilitate monitoring and management. The transparent plate body serves as an observation window, creating convenient conditions for the recording camera and the display screen to display the inside of the test tank.

[0022] Compared with the prior art, the utility model has the advantages that:

[0023] (1) The utility model adopts the way of leading water flow first, so that the water flow is in a stable state before contacting the filter core workpiece.

This method effectively avoids the possibility of bubbles generated by the impact of water flow on the filter core workpiece, so that the test result is more reliable and has repeatability.

[0024] (2)The utility model discloses a first drainage plate, second drainage plate and drainage groove etc. cleverly set parts, greatly reduce the generation of liquid's own bubble, when using, vertical first drainage plate can guide liquid from liquid inlet pipeline to the bottom of the box vertically, and the transverse second drainage plate guides liquid to the bottom of the box from the horizontal direction, in this way, the flow path of liquid has been optimized significantly, effectively reduces the occurrence of turbulence and vortex phenomenon, finally successfully reduces the formation of bubble.

This vertical introduction method can reduce the impact and turbulence of the liquid in the horizontal direction, thereby reducing the possibility of bubble formation. At the same time, the vertical falling of the liquid makes the path more direct, reducing the contact area with air. The horizontal second drainage plate 17 also cooperates with the drainage grooves 18 to guide the liquid from the vertical first drainage plate 16 to the bottom of the box. This design further disperses the liquid, making it evenly distributed at the bottom of the box, avoiding the direct impact of the liquid on the bottom of the box and generating bubbles. In addition, the horizontal drainage plate can effectively reduce the flow speed of the liquid, reducing the risk of turbulence and bubble formation. During the liquid introduction process, if the liquid directly impacts the bottom of the box or the test workpiece, it is easy to generate bubbles. Through the careful design of the drainage plate, the flow path of the liquid is optimized, reducing the possibility of direct impact and thereby reducing the risk of bubble formation. The synergistic effect of the vertical and horizontal drainage plates makes the liquid flow more stable, reducing turbulence and vortex, and ultimately reducing bubble formation.
