They are, of course, merely examples and are not intended to limit the utility model.
Embodiments of the utility model are described in detail below with reference to the accompanying drawings.
In this embodiment, a testing gas is continuously introduced into the ceramic membrane 500 to be tested until the pressure value of the testing gas reaches a certain value or a rattle occurs, and the package structure at the ceramic membrane element 510 and the end seal 520 of the ceramic membrane 500 is damaged, so that the specific pressure value corresponding to the damage of the package structure is used as a quantitative evaluation index of the package performance of the ceramic membrane, thereby being beneficial to the visual understanding of the related performance of the ceramic membrane by a user.
The ceramic film package performance gas inspection apparatus in this embodiment includes a gas supply unit 100. The gas supply unit 100 is used for supplying test gas, and may be used alone or in combination with an air compressor, a gas booster pump, or the like. Clean air can be used as the test gas in general, and the cost is low. If an inert gas such as nitrogen is used as the gas, a corresponding gas tank needs to be provided.
Because the ceramic membrane element 510 of the ceramic membrane 500 has a surface porous structure, the size of the pores of the conventional ceramic membrane element 510 cannot meet the requirement of intercepting gas molecules. Therefore, in order to achieve a pressure differential between the inside and outside of the ceramic membrane 500, thereby inducing the destruction of the package structure at the ceramic membrane element 510 and the end seal 520, a sealed environment needs to be constructed. Thus, the ceramic membrane packaging performance gas inspection device in this embodiment further includes the pressure-bearing sealing cabinet 200 and the gas pipe 300. Generally, the pressure-bearing sealing cabinet 200 is formed by processing metal plates such as pressure-resistant steel plates, so as to meet the detection requirement in a higher pressure environment. The shape of the pressure-bearing sealed cabinet 200 can be designed according to the requirements, such as cuboid type, cylindrical type, etc. In this embodiment, a rectangular parallelepiped type pressure-bearing sealed cabinet 200 is taken as an example, as shown in fig. 1. The interior of the pressure containing sealed cabinet 200 has a generally enclosed detection chamber 210. The detection chamber 210 is also rectangular in shape and serves as a placement area for the ceramic membrane 500 to be tested. One end of the gas delivery pipe 300 is connected to an output end of the gas supply unit 100. The other end of the gas delivery tube 300 extends into the detection chamber 210 and is provided with an adapter (not shown). A pressure gauge 400 is provided on the portion of the gas pipe 300 located outside the pressure-bearing sealed cabinet 200. The pressure gauge 400 may be a mechanical pressure gauge or an electronic pressure gauge to display the pressure of the test gas in the gas line 300 in real time.
In the test, if there are a plurality of filters 521 on the end seal 520 of the ceramic membrane 500, the filters 521 are plugged first, and only one filter 521 is reserved as an inlet for the test gas into the ceramic membrane 500. Meanwhile, the adapter tube 600 connects the air delivery tube 300 with the filter 521. The transfer tube 600 may employ flexible, crimpable metal tubing or the like to meet the connection requirements. After the assembly, the gas supply unit 100 continuously supplies the test gas into the ceramic membrane 500. Due to the interception of the pressure-bearing seal cabinet 200, the test gas may be stopped in the pressure-bearing seal cabinet 200 after being released from the surface of the ceramic membrane 500. When the pressure-bearing sealed cabinet 200 is restrained, the surface of the ceramic membrane 500 is gradually blocked from continuously releasing the test gas when the test gas in the pressure-bearing sealed cabinet 200 is more and more. When the amount Q1 of the test gas continuously introduced into the ceramic membrane 500 is greater than the amount Q2 of the gas released from the surface of the ceramic membrane 500, a pressure difference occurs between the inside and the outside of the ceramic membrane 500. When the pressure value of the test gas reaches a certain value or the rattle appears, the packaging structures at the ceramic membrane element 510 and the end seal 520 of the ceramic membrane 500 are destroyed, and the pressure value at the moment is recorded, so that the pressure value can be used as a quantitative evaluation index of the packaging performance of the ceramic membrane, and the surface packaging performance is visualized.
Further, the pressure-bearing sealed cabinet 200 includes a cabinet body 220 and a cabinet door 230. One side of the cabinet 220 is open. One side of the cabinet door 230 is hinged to one side of the open side of the cabinet 220. The other side of the cabinet door 230 is provided with a cooperating locking structure 240 at a position corresponding to the cabinet body 220. A sealing ring 250 is provided at an edge of the cabinet door 230 facing the cabinet 220. After the cabinet 220 and the cabinet door 230 are locked, the sealing ring 250 is pressed and deformed by the cabinet 220 and the cabinet door 230, and the joint of the cabinet 220 and the cabinet door 230 is further sealed. The hollow area inside the combined cabinet 220 and cabinet door 230 is the detection chamber 210.
Further, in order to fix the ceramic membrane 500, two first supporting frames 260 are provided at the bottom of the cabinet door 230. Three second support brackets 270 are provided on the back of the cabinet door 230. The first support frame 260 has a substantially H-shape, and the second support frame 270 has a substantially U-shape. When the ceramic membrane 500 is mounted substantially vertically in the detection chamber 210, the end seal 520 below the ceramic membrane 500 is fitted into the first support frame 260, and one side surface of the ceramic membrane element 510 is caught in the second support frame 270 while providing support along the length direction and the width direction of the ceramic membrane 500, as shown in fig. 2.
Further, a check valve 310 is provided on the gas delivery pipe 300. In this embodiment, the check valve 310 is used to restrict the test gas to flow from the gas supply unit 100 to the pressure-bearing sealing cabinet 200 only in one direction, so as to prevent the test gas from flowing back.
Further, a first heater (not shown) is also provided on the air delivery pipe 300. In this embodiment, the first heater may heat the test gas to a preset temperature (e.g., 30-35 ℃) to simulate the detection effect of the test gas with temperature on the sealing performance of the ceramic film. Similarly, a second heater may be disposed in the detection chamber 210 to heat the heating chamber 210 to a predetermined temperature (e.g. 30-35 ℃) so as to simulate the detection effect of the test environment temperature on the ceramic membrane sealing performance.
Further, a first safety air pipe 280 is further provided at the top of the pressure-bearing sealed cabinet 200, and a safety valve 281 is provided on the first safety air pipe 280. When the pressure value in the pressure-bearing sealing cabinet 200 exceeds the safety range, the safety valve 281 actively releases the test gas to reduce the pressure. Further, the exhaust direction of the outlet end of the first safety air pipe 280 is approximately vertical to the sky direction, so as to avoid safety accidents.
Further, a second safety air pipe 290 is further provided at the side of the pressure-bearing sealed cabinet 200, and an exhaust valve 291 is provided at the second safety air pipe 290. The exhaust valve 291 may be a manual valve or an electric valve. When the detection is completed, the exhaust valve 291 is opened gradually to release the test gas until the pressure in the pressure-bearing sealing cabinet 200 is restored to normal pressure, and then the tested ceramic membrane 500 can be taken out. Further, the exhaust direction at the outlet end of the second safety air pipe 290 is approximately vertical to the ground direction, so as to avoid safety accidents caused by the depressurization process.
Further, the pressure gauge 400 is an electronic pressure gauge, and the exhaust valve 291 is an electric valve. Meanwhile, the ceramic membrane packaging performance gas inspection device in the embodiment also comprises a controller (such as a common PLC controller) and an electronic component tester (not shown in the figure). The electronic type decimeter may be provided in the pressure-bearing sealed cabinet 200 or near the outside. The controller is connected with the electronic meter, the pressure gauge 400, the exhaust valve 291 and the air supply unit 100. In this embodiment, the controller may automatically control, monitor and record the detection process, so as to further improve the degree of intelligence.
