For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations. The following will describe the embodiments according to the overall structure of the present utility model.

[0027] Refer to Figures 1 to 6, in the embodiment of the present utility model, a gas separation membrane cell structure includes: a main housing 1, an intake pipe 2 penetrating through its interior is fixedly connected above the main housing 1, an exhaust pipe 3 penetrating through its interior is fixedly connected to the side of the main housing 1, a flow equalizing plate 4 is fixedly connected below the intake pipe 2 inside the main housing 1 for evenly dispersing the airflow entering through the intake pipe 2 and reducing the impact of local high-speed airflow on the coating film carrier. A side drawer slot 5 penetrating through its interior is opened on the side of the main housing 1, and a separation membrane fixing mechanism 6 is slidably connected inside the side drawer slot 5. Two groups of drawer locking mechanisms 7 are fixedly connected to the outside of the main housing 1. A lower pressure relief port 8 penetrating to its inside is opened above the main housing 1. A guiding square pipe 9 is fixedly connected above the main housing 1 and located above the lower pressure relief port 8. An upper pressure relief hole 10 penetrating to its outside is opened inside the guiding square pipe 9. Two groups of guiding screw rods 11 are fixedly connected inside the guiding square pipe 9 above the main housing 1. A sealing plug plate 12 is arranged above the lower pressure relief port 8. A through hole adapted to the guiding screw rod 11 is opened above the sealing plug plate 12. A second support spring 13 is sleeved outside the guiding screw rod 11. A pressure nut 14 adapted to it is arranged above the guiding screw rod 11. The guiding screw rod 11 penetrates through the through hole opened above the sealing plug plate 12 and is threadedly connected to the pressure nut 14. The second support spring 13 is located between the sealing plug plate 12 and the pressure nut 14;

[0028] The separation membrane fixing mechanism 6 includes a fixing drawer 61. A limiting strip is fixedly connected below the fixing drawer 61. A guiding groove adapted to the limiting strip is fixedly connected inside the main housing 1. A metal support mesh 62 is fixedly connected to the bottom of the fixing drawer 61. The mesh support of the metal support mesh 62 can effectively prevent the separation membrane from deforming and maintain its stable shape and performance. Two groups of fixing screw holes 63 are opened above the fixing drawer 61. A fixing screw rod 64 is threadedly connected inside the fixing screw holes 63. An upper pressing frame 65 is arranged above the fixing drawer 61. A separation membrane carrier 67 is arranged between the upper pressing frame 65 and the fixing drawer 61. Anti-slip strips are arranged below the upper pressing frame 65 to prevent the separation membrane carrier 67 from being displaced during use. Two groups of opening fixing plates 66 are symmetrically and fixedly connected to both sides of the upper pressing frame 65. Through holes adapted to the fixing screw rod 64 are opened inside the opening fixing plates 66.

[0029] Adopting the above scheme: When it is necessary to adjust the pressure relief threshold, only need to rotate the two groups of pressurizing nuts 14 to adjust the compression degree of the two groups of second support springs 13, then the pressure relief threshold can be adjusted. When the air pressure inside the main housing 1 is too high, the sealing plug plate 12 moves upward under the action of the air pressure, compressing the second support spring 13, and the gas can be discharged from the upper pressure relief hole 10. Moreover, the greater the internal air pressure, the smaller the area of the upper pressure relief hole 10 blocked by the sealing plug plate 12, so the faster the pressure relief. When it is necessary to fix or replace the separation membrane carrier 67, only need to unscrew the fixing screw 64, place the separation membrane carrier 67 between the upper pressing frame 65 and the fixed drawer 61, and use the fixing screw 64 to pass through the opening fixing plate 66 and be threadedly connected with the fixing screw hole 63.

[0030] Refer to Figure 1 and Figure 5 , the drawer locking mechanism 7 includes a fixed block 71. A spring groove 72 is opened below the fixed block 71. A slider groove 73 penetrating to the outside of the fixed block 71 is opened inside the spring groove 72. A first support spring 74 is fixedly connected inside the spring groove 72. The other end of the first support spring 74 is fixedly connected with a locking block 75. A moving slider 76 is fixedly connected to the side of the locking block 75. The moving slider 76 is slidably connected with the slider groove 73. The side of the locking block 75 is in a slope shape. Sliders are fixedly connected to both sides of the locking block 75. A chute adapted to the slider is opened inside the spring groove 72.

[0031] Adopting the above scheme: When the separation membrane fixing mechanism 6 is inserted into the side drawer slot 5, it will squeeze the locking block 75 and compress the first support spring 74. After the separation membrane fixing mechanism 6 is completely inserted into the side drawer slot 5, the locking block 75 locks the separation membrane fixing mechanism 6 under the pressure of the first support spring 74. When it is necessary to take out the separation membrane fixing mechanism 6, the two groups of moving sliders 76 can be pushed to compress the first support spring 74 again to completely receive the locking block 75 into the spring groove 72. At this time, the separation membrane fixing mechanism 6 can be easily pulled out.

[0032] The working principle of the present utility model is: First, connect the air inlet pipe 2 and the air outlet pipe 3 to an external gas source and a gas collection system respectively;

[0033] Insert the separation membrane fixing mechanism 6 into the main housing 1 through the side drawer slot 5, and ensure that the limiting strip below the fixed drawer 61 is aligned and slid with the guiding groove inside the main housing 1. At this time, the side of the separation membrane fixing mechanism 6 will squeeze the locking block 75 and compress the first support spring 74. After the separation membrane fixing mechanism 6 is completely inserted into the side drawer slot 5, the locking block 75 locks the separation membrane fixing mechanism 6 under the pressure of the first support spring 74;

[0034] By rotating the pressure - regulating nut 14, the compression degree of the second support spring 13 can be adjusted, thereby setting an appropriate pressure - relief threshold. This step affects the closing degree of the sealing plug plate 12 on the upper pressure - relief hole 10, and further affects the sensitivity and speed of gas pressure - relief;

[0035] Start the external gas source. The gas enters the main housing 1 through the air inlet pipe 2. When the air flow passes through the flow - equalizing plate 4, it is evenly dispersed, reducing the local high - speed impact on the separation - membrane carrier 67, which helps to extend the service life of the separation membrane and maintain a stable separation efficiency. Under the action of the separation - membrane carrier 67, the mixed gas is separated into different components, and the separated gas is discharged through the air outlet pipe 3 and enters the subsequent treatment or collection system;

[0036] During the separation process, the air pressure inside the main housing 1 increases. When the air pressure exceeds the set threshold, the sealing plug plate 12 will move upward under the action of the air pressure, compressing the second support spring 13, so that the gas can be discharged through the upper pressure - relief hole 10, thereby realizing automatic pressure - relief and protecting the equipment and the separation membrane from over - pressure damage. The greater the internal air pressure, the smaller the area of the upper pressure - relief hole 10 blocked by the sealing plug plate 12, and the faster the pressure - relief process will be;

[0037] When it is necessary to take out the separation - membrane fixing mechanism 6, two groups of moving sliders 76 can be pushed to compress the first support spring 74 again to completely retract the locking block 75 into the spring groove 72. At this time, the separation - membrane fixing mechanism 6 can be easily pulled out;

[0038] When the separation - membrane carrier 67 reaches the end of its service life or needs to be replaced, take out the separation - membrane fixing mechanism 6, unscrew the fixing screw 64, take out the old separation - membrane carrier 67 from the fixing drawer 61, put in a new separation - membrane carrier 67, and use the fixing screw 64 to pass through the opening fixing plate 66 and be thread - connected with the fixing screw hole 63;

[0039] The above - mentioned is only the preferred specific implementation mode of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
