[0002] Flat sheet membranes are a type of membrane sheet with good permeability. They contain a support layer with high mechanical strength and a unique double-layer structure, which reduces the risk of membrane damage and leakage of contaminants. They are easy to inspect and replace individually, saving on replacement costs. Primarily used in wastewater treatment, they offer advantages such as high-efficiency separation and purification, improved treatment efficiency and stability, and reduced energy consumption and costs. The permeability test of flat sheet membranes is one of the important indicators for evaluating their performance and is of great significance for optimizing wastewater treatment processes and improving effluent quality.

[0003] In existing permeability tests, the sheet membrane is immersed in a solution, making it inconvenient to remove and replace it with a new one for retesting. Furthermore, it is not convenient to place the sheet membrane in solutions of different concentrations for testing, affecting the comprehensiveness and efficiency of the test results.

[0004] Therefore, it is necessary to provide a new penetration performance testing component to solve the above-mentioned technical problems. Utility Model Content

[0021] The present invention will be further described below with reference to the accompanying drawings and implementation examples.

[0022] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in Figure 1 A schematic diagram of a preferred embodiment of the permeability testing component provided by this utility model; Figure 2 for Figure 1 The diagram shows the structure of the components to be replaced. Figure 3 for Figure 2 A magnified structural diagram of point A is shown below; Figure 4 for Figure 1 The diagram shows the structure of the control component. A permeability testing component includes a test chamber 1, a fixing box 2 at the bottom of the test chamber 1, and a partition 3 fixedly connected to the inner side of the test chamber 1.

[0023] In the specific implementation process, such as Figure 1 , Figure 2 and Figure 3As shown, the replacement assembly 4 is located on the top of the test box 1. The replacement assembly 4 includes a fixed rod 41, a support sleeve 42, a connecting rod 43, and a ratchet 44. The fixed rod 41 is fixedly connected to the top of the test box 1. The support sleeve 42 is fixedly connected to the top of the fixed rod 41. The connecting rod 43 is rotatably connected to the inner side of the support sleeve 42. The ratchet 44 is fixedly connected to the outer side of the connecting rod 43.

[0024] A fixing frame 6 is slidably connected to the outside of the fixing rod 41, a cover plate 7 is fixedly connected to the bottom of the fixing frame 6, and a handle 10 is fixedly connected to one end of the connecting rod 43.

[0025] A steel wire rope 8 is fixedly connected to the top of the cover plate 7. A winding drum 9 is provided at one end of the steel wire rope 8. The inner side of the winding drum 9 is fixedly connected to the outer side of the connecting rod 43.

[0026] A mounting plate 11 is provided at the bottom of the cover plate 7, and a flat membrane assembly 12 is fixedly connected to the bottom of the mounting plate 11. Bolts 13 are provided inside the cover plate 7.

[0027] A fixing plate 14 is fixedly connected to the outside of the fixing rod 41. One end of the fixing plate 14 is slidably connected to a limiting plate 15, and the bottom of the limiting plate 15 is fixedly connected to a limiting rod 16.

[0028] A spring 17 is provided on the outer side of the limiting rod 16, a connecting plate 18 is fixedly connected to one end of the limiting rod 16, and a support frame 19 is slidably connected to the outer side of the limiting rod 16. The top of the support frame 19 is fixedly connected to the bottom of the fixing plate 14.

[0029] It should be noted that: Test chamber 1 is supported by fixing box 2, and partition 3 facilitates the division of test chamber 1 into two test pools for holding test solutions of different concentrations. Two fixing rods 41 are fixed to the top of test chamber 1 for support and stability. Flat sheet membrane module 12 is a complete membrane assembly unit composed of membrane sheet, supporting base layer, fixing frame, etc. During testing, flat sheet membrane module 12 is immersed in test chamber 1, and cover plate 7 covers the opening of test chamber 1. Support frame 19 limits spring 17, and fixing plate 14 fixes support frame 19. Fixing plate 14 supports and limits limiting plate 15. Pulling down connecting plate 18 moves limiting rod 16 and limiting plate 15 downwards, simultaneously limiting spring 17. 7. Compression causes the limiting plate 15 to disengage from the ratchet 44, thereby relaxing the restriction on the ratchet 44. When the handle 10 is rotated, under the support of the two support sleeves 42, the connecting rod 43 drives the ratchet 44 and multiple winding drums 9 to rotate, winding the corresponding wire ropes 8, thereby causing the wire ropes 8 to pull the two cover plates 7 to rise. When they rise to the appropriate position, the pressure on the connecting plate 18 is released. Under the action of the spring 17, the limiting rod 16 and the limiting plate 15 are reset, so that the limiting plate 15 is engaged with the ratchet 44, fixing the rising height and preventing the connecting rod 43 from rotating uncontrollably. The bolt 13 is loosened, making it easy to remove the mounting plate 11 with the flat film assembly 12 fixed from the cover plate 7, facilitating the replacement of the new flat film assembly 12.

[0030] refer to Figure 1 and Figure 4 As shown, the control component 5 is located on both sides of the test box 1. The control component 5 includes a delivery pipe 51, a pressure valve 52 and a heating plate 53. Both sides of the test box 1 are connected to the delivery pipe 51. The pressure valve 52 is located on the outside of the delivery pipe 51 and the heating plate 53 is located on the inside of the fixed box 2.

[0031] The control assembly 5 also includes a temperature sensor 54 and a control box 55. The temperature sensor 54 is provided on one side of the inner wall of the test chamber 1, and the control box 55 is fixedly connected to the top of the test chamber 1.

[0032] The test chamber 1 is connected to a drain pipe 20, and one end of the delivery pipe 51 is connected to a water pump 21. The water pump 21 is connected to a connecting pipe 22.

[0033] It should be noted that: the inside of the delivery pipe 51 is connected to the inside of the test chamber 1. With the action of the two sets of water pumps 21, the connecting pipe 22 and the delivery pipe 51, it is convenient to inject solutions of different concentrations into the test chamber 1 respectively, so as to facilitate simultaneous testing and improve testing efficiency. With the action of the control box 55, it is convenient to control the start and stop of the heating plate 53, and with the cooperation of the temperature sensor 54, it is convenient to set the required water temperature. By measuring the permeate volume over a certain period of time, the permeate flux of the flat sheet membrane module 12 can be easily obtained. By controlling and adjusting the two pressure valves 52, the fluid pressure entering the flat sheet membrane module 12 can be directly controlled to ensure the stability and accuracy of the operating pressure, which is convenient for permeability testing. With the action of the two drain pipes 20, the solution can be discharged.

[0034] The working principle of the penetration performance testing component provided by this utility model is as follows:

[0035] In use, the partition 3 facilitates the division of the test chamber 1 into two test pools, allowing for testing with solutions of different concentrations. This reveals the permeability performance of the flat sheet membrane module 12 under different concentration conditions, enhancing the comprehensiveness of the test. The water pump 21, connecting pipe 22, and delivery pipe 51 facilitate the delivery of solutions of different concentrations to the test chamber 1. The pressure valve 52 controls the fluid pressure as needed, ensuring the stability of the operating pressure. The control box 55, heating plate 53, and temperature sensor 54 set the required test water temperature. With the coordination of pressure control, solution solubility, and specific test time, the permeation flux and permeability of the flat sheet membrane module 12 are tested. When it is necessary to remove or replace the flat sheet membrane module 12 immersed in the solution, the connecting plate 18 is pressed down, causing the connecting plate 18 to move the limiting rod 16 and the limiting plate 15 downwards. Under the action of the support frame 19, the spring 17 is compressed, and the limiting plate 1... The movement of 5 disengages it from ratchet 44, releasing the restriction on ratchet 44. By rotating handle 10, connecting rod 43 rotates under the limit of fixed rod 41 and support sleeve 42, thereby driving multiple winding drums 9 to rotate, causing the corresponding wire ropes 8 to wind up. This causes the two sets of wire ropes 8 to pull the two cover plates 7 up respectively. When the cover plate 7 moves, it drives the fixed frame 6 to slide under the limit of fixed rod 41, improving the stability of the cover plate 7. After the cover plate 7 drives the flat film assembly 12 to a suitable position, the pressure on connecting plate 18 is released. Under the action of spring 17, the limit rod 16 and limit plate 15 are reset, so that the limit plate 15 engages with ratchet 44 to limit the height position and prevent the connecting rod 43 from rotating uncontrollably. The bolts 13 are loosened to facilitate the removal of the mounting plate 11 with the flat film assembly 12 fixedly installed from the cover plate 7. At the same time, it is convenient to install and replace the new flat film assembly 12 for retesting, improving the comprehensiveness of the test results.
