DETAILED DESCRIPTION

[0029] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only a portion of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work should fall within the scope of protection of the present invention.

[0030] like Figures 1 to 4 As shown, a device for capturing carbon dioxide in air in one embodiment of the present invention includes: a capture box 1, a first capture mechanism 2 and a second capture mechanism 3.

[0031] like Figures 1 to 2 As shown, one end of the capture box 1 is fixedly connected to an air inlet hopper 101 for facilitating the transportation of the gas. A capture ball is provided in the capture box 1, and the surface of the capture ball is loaded with a material capable of absorbing carbon dioxide, so that when the air passes through the capture box 1, the capture ball can absorb the carbon dioxide in the air.

[0032] Among them, the air inlet hopper 101 is equipped with a delivery air pipe 102 for delivering air, thereby facilitating the capture of carbon dioxide from the air. Preferably, the other end of the delivery air pipe 102 is connected to an external air pump, which increases the amount of contact between carbon dioxide in the air and the capture material on the capture ball and semicircular capture plate 304, thereby improving the carbon dioxide capture efficiency. In addition, the external air pump also has the function of controlling the air flow and flow rate. A plurality of support column legs 103 are fixedly connected to the bottom of the capture box 1 to support the capture box 1, making it less likely to shake or tilt, and providing support for the device.

[0033] like Figures 1 to 2As shown, a sealing plug 104 is threadedly connected to the capture box 1 to seal the lower end of the capture box 1, thereby preventing the capture balls from leaking. Furthermore, after the capture balls have been used for a period of time, the staff can remove the sealing plug 104 to allow the capture balls to fall downward, making it easier to replace the capture balls. The capture material that has completed carbon dioxide adsorption can then be regenerated and the carbon dioxide collected. A guide ramp 105 is installed within the capture box 1 to guide the capture balls toward the riser 201, thereby facilitating the upward movement of the auger 203, allowing the capture balls to fully contact the air and improve the carbon dioxide capture efficiency.

[0034] Specifically, a plurality of evenly distributed exhaust holes 106 are drilled on one end of the capture box 1 away from the air inlet hopper 101 for exhausting air, thereby facilitating subsequent air discharge from the air delivery pipe 102 .

[0035] like Figures 1 to 3 As shown, the first capture mechanism 2 is installed within the capture box 1. It includes a riser 201, which cooperates with an auger 203 to lift the capture ball, allowing it to slide out of a slide 204, thereby increasing the contact area between the ball and the air. A drive shaft 202 is inserted into the riser 201, supporting and rotating the auger 203 to facilitate lifting the capture ball. The auger 203 is mounted on the drive shaft 202.

[0036] Specifically, a slide 204 is fixedly connected to the top of the rising cylinder 201 for sliding out the collecting balls so that the collecting balls can fall from the lower leakage holes 207 of different sizes, thereby increasing the contact area between the collecting balls and the air.

[0037] like Figures 1 to 3 As shown, one end of the drive shaft 202 is fixedly connected to a main drive motor 205, which is mounted on the capture box 1 and is used to drive the drive shaft 202 to rotate, thereby providing power to raise the capture balls and enable them to slide off the slide 204. A fixed bearing 206 is fixedly connected between the end of the drive shaft 202 closest to the main drive motor 205 and the capture box 1, which is used to fix the drive shaft 202, so that the rotation of the drive shaft 202 is not easily affected, and thus it is less likely to wobble or skew.

[0038] like Figures 1 to 3 As shown, slide 204 is provided with multiple lower leakage holes 207 of varying sizes. These holes gradually increase in size from ascending tube 201 toward air inlet hopper 101, allowing capture balls to fall through these holes as they slide on slide 204, thereby enhancing contact between the capture balls and air. Multiple thin fixing rods 208 are fixedly connected between ascending tube 201 and capture box 1 to secure ascending tube 201 and prevent it from shaking or tilting.

[0039] like Figures 1 to 4 As shown, the second capture mechanism 3 is mounted on the capture box 1 and includes a rotating adjustment column 301 for supporting a pair of semicircular capture plates 304. A fixed shaft 302 is inserted into the rotating adjustment column 301 to support and rotate the rotating adjustment column 301. Support bearings are fixedly connected to both ends of the fixed shaft 302. One end of the fixed shaft 302 is fixedly connected to a secondary drive motor 303, which provides power for driving the rotating adjustment column 301. The secondary drive motor 303 is mounted on the capture box 1.

[0040] like Figures 1 to 4 As shown, a pair of semicircular capture plates 304 are provided on the rotating adjustment column 301, and the semicircular capture plates 304 are loaded with a material that can absorb carbon dioxide to absorb carbon dioxide in the air. In addition, by utilizing a pair of semicircular capture plates 304, the pair of semicircular capture plates 304 can be respectively placed in the capture box tube 1 and the fixed box 305, thereby facilitating the replacement of one of the semicircular capture plates 304 without easily affecting the other semicircular capture plate 304 in absorbing carbon dioxide.

[0041] like Figures 1 to 4 As shown, multiple fixed boxes 305 are fixed to the outside of the capture box 1. A pair of semicircular capture plates 304 are respectively installed in the capture box 1 and the fixed boxes 305. This facilitates the replacement of the semicircular capture plates 304, allowing the capture material that has completed carbon dioxide adsorption to be regenerated and the carbon dioxide to be collected. A door 306 is mounted on the fixed boxes 305, and a handle 307 is provided on the door 306 for easy operation.

[0042] During specific use, air is transported into the capture box 1 through the air delivery pipe 102, and then the transported air comes into contact with the semicircular capture plates 304, so that the semicircular capture plates 304 loaded with carbon dioxide adsorbent material can capture carbon dioxide in the air. After one of the semicircular capture plates 304 has been used for a period of time, the staff starts the secondary drive motor 303, which drives the pair of semicircular capture plates 304 to rotate, and rotates the unused semicircular capture plate 304 into the capture box 1, while the other semicircular capture plate is rotated into the fixed box 305. Then, the staff can open the box door 306 to remove the semicircular capture plate 304 that has been used for a period of time without affecting the use of the device.

[0043] Moreover, the start-up of the main drive motor 205 can also drive the drive shaft 202 and the auger 203 to rotate, and the auger 203 will drive the capture ball loaded with carbon dioxide adsorption material to move upward, so that the capture ball can slide out from the slide 204. At this time, the capture balls of different sizes will fall down from different lower leakage holes 207 respectively, and then can fully contact with the transported gas, thereby improving the capture efficiency of carbon dioxide.

[0044] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.

[0045] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
