[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0029] The embodiment of the utility model discloses a high-pressure flat membrane testing device.

[0030] Example 1

[0031] The utility model provides Figure 1-4The high-pressure flat membrane testing equipment shown includes a testing body 1 and a plurality of supporting legs 2 fixedly arranged at the bottom of the testing body 1, and is characterized in that a testing membrane pool 3 is fixedly embedded inside the testing body 1, and two symmetrically arranged placement plates 4 are fixedly embedded inside the testing membrane pool 3, the placement plates 4 pass through the testing membrane pool 3, and a sealing airbag 5 is fixed in each of the two placement plates 4. The cross-section of the placement plates 4 and the sealing airbag 5 is U-shaped, and a testing diaphragm 6 is wrapped between the two sealing airbags 5. The two sealing airbags 5 are connected to each other on the side away from each other and are provided with an air inlet pipe 24 and an air outlet pipe 25. The air inlet pipe 24 and the air outlet pipe 25 both pass through the testing body 1 and are respectively fixed with an inflation pump 26 and an exhaust pump 27. The inflation pump 26 and the exhaust pump 27 are both fixed to the outer wall of the testing body 1, and both ends of the two placement plates 4 are sealed with a cover plate 7. The two sides of the testing membrane pool 3 are respectively connected with a liquid inlet pipe 8 and a liquid outlet pipe 9, and the side of the testing membrane pool 3 is connected with a flow sensor 10. A controller 11 is fixed on the top of the testing body 1.

[0032] When testing the flat membrane, the test diaphragm 6 is located in the sealing airbag 5. At this time, the sealing airbag 5 is inflated through the air inlet pipe 24 and the air pump 26, so that the test diaphragm 6 can be sealed and wrapped. At the same time, under the setting of the cover plate 7, the test position of the test diaphragm 6 is determined, and then the test solution enters the test membrane pool 3 through the liquid inlet pipe 8, so that the solution can circulate through the test diaphragm 6. At this time, the flow sensor 10 detects the solution flowing out of the other side of the test membrane pool 3, thereby completing the test of the diaphragm. When the test diaphragm 6 needs to be tested, When replacing, first extract the gas inside the sealing airbag 5 through the air outlet pipe 26 and the exhaust pump 27. At this time, the test diaphragm 6 is not squeezed by the seal. Then move the two cover plates 7 at the same time so that the two cover plates 7 open the two ends of the placement plate 4. At this time, the used test diaphragm 6 can fall from the bottom under its own gravity. Then place a new diaphragm in the sealing airbag 5, and inflate the sealing airbag 5 to squeeze and position it. Then move the two cover plates 7 back to their original position, the position of the diaphragm can be determined again, and stable testing can be carried out.

[0033] Example 2

[0034] Example 2, based on Example 1, aims to enable the two cover plates 7 to move simultaneously and open the placement plate 4, as follows: Figure 2As shown, a telescopic rod 21 is fixed to the outer wall of the cover plate 7, and a fixed plate 22 is fixed to the end of the telescopic rod 21. The fixed plate 22 is fixedly connected to the outer wall of the test body 1. A sealing gasket 23 is fixed to the side close to the two cover plates 7. The sealing gasket 23 is in sealing contact with the outer wall of the test membrane pool 3. A synchronous driving mechanism for driving the two cover plates 7 to move synchronously is provided between the two cover plates 7. The synchronous driving mechanism includes a rotating plate 12 and a support rod 13. The support rod 13 is fixed to the back side of the test body 1, and the rotating plate 12 is rotatably sleeved on the outside of the support rod 13. The rotating plate 12 and the support rod 13 are rotatably connected through bearings. Push holes 14 are provided at both ends of the interior of the rotating plate 12. Push rods 15 are fixed to the back sides of the two cover plates 7, and the push rods 15 are slidably arranged in the push holes 14.

[0035] During operation, the cover plate 7 is effectively sealed against the test body 1 by the sealing gasket 23, thereby ensuring the sealing of the test diaphragm 6 during operation. At the same time, the cover plate 7 is laterally limited by the telescopic rod 21 and the fixed plate 22. When the cover plate 7 needs to be moved, the rotating plate 12 can rotate around the support rod 13 under the support of the support rod 13. At this time, the pushing hole 14 can push the push rod 15 inside it, so that the push rod 15 drives the cover plate 7 to move laterally. Since the two ends of the rotating plate 12 rotate synchronously, the two hanging plates 7 can be moved at the same time and the two ends of the placement plate 4 can be opened, which is convenient for the falling and reinstallation of the test diaphragm 6, thereby improving the installation convenience of the test diaphragm 6.

[0036] Example 3

[0037] Example 3 is based on Example 2 in order to determine the position of the cover plate 7 after the two cover plates 7 move, as shown in FIG. Figure 2-4 As shown, two positioning holes 16 are provided on the back side of the test body 1, a connecting plate 17 is fixedly provided on the outer wall of the rotating plate 12, a positioning rod 18 is slidably passed through the interior of the connecting plate 17, one end of the positioning rod 18 is inserted into the positioning hole 16, and a pull ring 19 is rotatably provided on the other end of the positioning rod 18. The pull ring 19 is rotatably connected to the end of the positioning rod 18 through a hinge, and a spring 20 is sleeved on the end of the positioning rod 18 close to the positioning hole 16, and the two ends of the spring 20 are fixedly connected to the positioning rod 18 and the connecting plate 17 respectively.

[0038] Before rotating the rotating plate 14, the pull ring 19 can be pulled through the pull hole so that the pull ring 19 drives the positioning rod 18 to move. At this time, the positioning rod 18 is pulled out of the positioning hole 16 and squeezes the spring 20. Then, the rotating plate 14 can be driven to rotate through the connecting plate 17. When the rotating plate 14 drives the two cover plates 7 to move horizontally, the connecting plate 17 moves to the position of the positioning rod 16 on the other side, and then the pull ring 19 is released. Under the elastic force of the spring 20, the positioning rod 18 can quickly rebound and be inserted into the positioning hole 16, thereby fixing the position of the connecting plate 17 and the rotating plate 14, thereby ensuring that the cover plate 7 is not offset after movement due to external influences, thereby ensuring the stability of the test diaphragm 6 during installation.

[0039] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
