Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example

[0027] like Figure 1-6 As shown, a carbon dioxide membrane separation and collection device includes a base 1. First fixing plates 2 are fixedly connected to both sides of the top of the outer surface of the base 1. A first retaining seat 3 is rotatably connected to the inner side of the first fixing plate 2. A first roll 4 is engaged inside the first retaining seat 3, and a separation membrane 5 is wound around the outer surface of the first roll 4. A second fixing plate 6 is fixedly connected to the outer surface of the base 1 away from the first fixing plate 2. A second retaining seat 7 is rotatably connected to the inner side of the second fixing plate 6. A second roll 8 is engaged inside the second retaining seat 7 and wound around the separation membrane 5. A support rod 9 is fixedly connected to the top of the back of the base 1. A connector 10 is rotatably connected to the middle of the outer surface of the support rod 9. A top seat 11 is fixedly connected to the outer surface of the connector 10. A through groove 32 is formed on the outer surface of the top seat 11 and the base 1 near the separation membrane 5, and the through groove 32 penetrates the base 1 and the top seat 11.

[0028] In practical use, the first roll 4, the separating membrane 5, the second roll 8, the top seat 11, and the through groove 32 are arranged such that the top seat 11 is rotatably connected to the outer surface of the support rod 9 via the connector 10, connecting it to the base 1. This allows for easy rotation and opening / closing. After prolonged use, it facilitates opening the top seat 11 to inspect and maintain the internal components, extending the device's lifespan. Upon opening the top seat 11, the first roll 4 with the separating membrane 5 is secured inside the two sets of first retainers 3, and the second roll 8 is secured inside the second retainer 7 and the third retainer 22. The separating membrane 5 unfolds and winds around the second roll 8, closing the top seat. In unit 11, under the action of separation membrane 5, carbon dioxide molecules are selectively allowed to pass through, while other gases are blocked above the membrane. After long-term use, impurities adhere to the surface of separation membrane 5. When the second roll 8 is rotated, the used separation membrane 5 is wrapped around the outer surface of the second roll 8, and the separation membrane 5 wrapped around the unused surface of the first roll 4 is unwound to continue the carbon dioxide separation and capture work. This reduces the time loss caused by intermittent operation, improves the continuity and efficiency of carbon dioxide separation and capture, and thus ensures the continuous separation and processing effect of the device, effectively improving the working efficiency.

[0029] In this embodiment, a first sealing gasket 12 is fixedly connected to the top of the inner side of the base 1, and a second sealing gasket 13 is fixedly connected to the bottom of the inner side of the top seat 11.

[0030] In practical use, the first sealing gasket 12 and the second sealing gasket 13 can enhance the sealing at the connection between the top seat 11 and the inner side of the base 1 when the top seat 11 is closed, and can also enhance the sealing at the connection between the top seat 11, the base 1 and the separation membrane 5, thus preventing air leakage and enhancing the sealing effect.

[0031] In this embodiment, a first locking member 14 is fixedly connected to the bottom of the front side of the top seat 11, and a limiting member 15 is fixedly connected to the top of the front side of the base 1.

[0032] In practical use, by setting the first locking piece 14 and the limiting piece 15, the first locking piece 14 is pried inward, which makes it easy for the limiting piece 15 to connect or separate from the first locking piece 14, so that the top seat 11 can be opened and closed conveniently and the limiting is flexible.

[0033] In this embodiment, a box body 16 is fixedly connected to the outer surface of the base 1 near the second roll 8, and a rotating rod 17 is rotatably connected to one side of the inner side of the box body 16. A rocker arm 18 is fixedly connected to one end of the rotating rod 17.

[0034] In practical use, the rocker arm 18 is fixed to one end of the rotating rod 17, which facilitates operation and control of the rotating rod 17, makes it easier to apply force with the hand, and increases the convenience of use.

[0035] In this embodiment, a worm gear 19 is fixedly connected to one side of the outer surface of the rotating rod 17, a worm wheel 20 is meshed with the outer surface of the worm gear 19, a connecting rod 21 is fixedly connected to the middle of the inner side of the worm wheel 20, one end of the connecting rod 21 passes through the box body 16, a third retainer 22 is fixedly connected to the end of the connecting rod 21 that passes through the box body 16, and the other end of the connecting rod 21 is rotatably connected to the box body 16.

[0036] In practical use, through the arrangement of worm 19 and worm wheel 20, worm 19 rotates under the action of rotating rod 17, thereby driving worm wheel 20 to drive third chuck 22 to rotate through connecting rod 21, causing second roll 8 to rotate and rewind the used separation membrane 5. Based on the difference in tooth angle, worm 19 and worm wheel 20 can produce a self-locking phenomenon, which has high reliability and safety, and makes the position of separation membrane 5 relatively stable during use.

[0037] In this embodiment, a fan 23 is fixedly connected to one side of the upper surface of the top seat 11, and a heating box 24 is fixedly connected to the outer surface of the fan 23.

[0038] In practical use, the heating box 24 can heat the air introduced by the fan 23 to reduce the moisture content in the carbon dioxide gas to a minimum. This eliminates the need to dry the collected carbon dioxide gas, facilitating its utilization and storage and improving the practicality of the device.

[0039] In this embodiment, a conveying pipe 25 is fixedly connected to the middle of the outer surface of the heating box 24, a fixing pipe 26 is fixedly connected to one end of the conveying pipe 25, the fixing pipe 26 is fixedly connected to the top seat 11, and a nozzle 27 is fixedly connected to the lower surface of the fixing pipe 26.

[0040] In practical use, through the setting of the nozzles 27, multiple nozzles 27 are evenly fixed on the lower surface of the fixed tube 26 in a horizontal array. The delivery tube 25 delivers heated air to the inside of the nozzles 27 through the fixed tube 26, so that the device can separate carbon dioxide in the air more evenly.

[0041] In this embodiment, a connecting plate 28 is fixedly connected to the middle of the inner side of the top seat 11. A second clip 29 is fixedly connected to both sides of the lower surface of the connecting plate 28. A filter plate 30 is clipped onto the outer surface of the second clip 29. A limiting groove 31 is formed on the outer surface of the filter plate 30 near the second clip 29.

[0042] In practical use, by setting the filter plate 30, the two adjacent sets of second clips 29 are bent inward to facilitate the installation of the filter plate 30 through the limiting groove 31, making it easy to install and disassemble, and easy to clean and replace after long-term use, ensuring good filtration effect. The filter plate 30 filters the air entering the device, which can remove impurities and improve the purity of the gas separated later.

[0043] Working principle: In use, open the top seat 11, and insert the first roll 4 with the separation membrane 5 into the two sets of first retainers 3. Insert the second roll 8 into the second retainer 7 and the third retainer 22. Unwind the separation membrane 5 and wrap it around the second roll 8. Close the top seat 11. The first sealing gasket 12 and the second sealing gasket 13 prevent air leakage. Insert the first retainer 14 into the limiting member 15 to fix the top seat 11. The heating box 24 heats the air introduced by the fan 23 to reduce the moisture content in the carbon dioxide gas to a minimum. The delivery pipe 25 delivers the heated air to the nozzle 27 through the fixed pipe 26, making the separation of carbon dioxide in the air more uniform. The filter plate 30 filters the air entering the device, improving the purity of the gas to be separated. Under the action of the separation membrane 5, carbon dioxide molecules are selectively allowed to pass through, while other gases are blocked above the membrane, thus completing the separation and capture of carbon dioxide. After long-term use, impurities adhere to the surface of the separation membrane 5. The rocker arm 18 controls the rotation of the rotating rod 17. The worm gear 19 drives the third chuck 22 to rotate through the worm wheel 20 and the connecting rod 21, causing the second roll 8 to rotate. The used separation membrane 5 is wrapped around the outer surface of the second roll 8, and the separation membrane 5 wrapped around the unused first roll 4 is unwound to continue the carbon dioxide separation and capture work, improving the continuity and efficiency of carbon dioxide separation and capture.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
