[0029] Example:

[0030] As attached Figure 1 To Attachment Figure 8 As shown:

[0031] The utility model provides a carbon dioxide capture and sealing device, including a workbench 11 and a weighing platform 12, wherein the weighing platform 12 is arranged below the workbench 11, and a sealing tank 13 is arranged on the top of the weighing platform 12, and the weight of the sealing tank 13 can be monitored by the weighing platform 12 to detect whether the sealing tank 13 is full; a sealing component is arranged on the sealing tank 13, and the sealing component includes a sealing plug 21 which can seal a liquid inlet 14 at the top of the sealing tank 13, and the sealing plug 21 is penetrated in the liquid inlet 14. During the carbon dioxide liquefaction process, the sealing plug 21 is opened to allow the liquefied carbon dioxide to smoothly enter the sealing tank 13, and a liquefaction pipeline 15 and a liquefaction chamber 16 therein are arranged on the workbench 11, and the entered carbon dioxide is liquefied by a cooling mechanism 17. A carbon dioxide inlet pipe 18 is provided at one end of the liquefaction pipeline 15, and the carbon dioxide inlet pipe 18 is connected to the liquefaction chamber 16. A liquid outlet 19 is provided on the corresponding surface of the workbench 11 and the liquefaction pipeline 15. A liquid collecting funnel 20 is provided at the bottom of the liquid outlet 19 on the workbench 11. The liquid collecting funnel 20 is connected to the liquefaction chamber 16 through two groups of liquid outlets 19. The liquefied carbon dioxide will enter the sealing tank 13 at the bottom through the liquid outlet 19 and the liquid collecting funnel 20; a liquid outlet component that can press down a sealing plug 21 is provided at the bottom of the liquid collecting funnel 20.

[0032] Please refer to Figure 3 , Figure 4 and Figure 5As shown, the sealing assembly also includes a sealing spring 22, a sealing cavity 23 is provided in the sealing tank 13, a mounting bracket 24 is installed on the inner wall of the sealing cavity 23, one end of the sealing spring 22 is connected to the mounting bracket 24, and the other end is connected to the sealing plug 21, and the elastic force of the spring is utilized, and when the carbon dioxide is liquefied, the sealing plug 21 is automatically pushed to seal the liquid inlet 14; this automatic sealing mechanism not only improves the operating efficiency, but also ensures that the carbon dioxide will not leak during the entire sealing process, greatly enhancing safety; the sealing cavity 23 is connected to the liquid inlet 14.

[0033] Please refer to Figure 2 and Figure 6 As shown, the liquid outlet component includes a liquid outlet tube 31, a through groove is provided at the bottom of the liquid collecting funnel 20, the liquid outlet tube 31 is installed at the bottom of the through groove, and a freely slidable liquid outlet tube 32 is penetrated inside the liquid outlet tube 31, and the bottom end of the liquid outlet tube 32 can contact the sealing plug 21.

[0034] Please refer to Figure 6 As shown, the liquid outlet assembly also includes a pressing cylinder 33 that can drive the liquid outlet pipe 32 to press down the sealing plug 21. The pressing cylinder 33 is installed at the bottom of the liquid outlet tube 31. At the same time, a connecting rod 34 is provided on one side of the liquid outlet pipe 32, and one end of the connecting rod 34 is connected to the pneumatic rod of the pressing cylinder 33; when the liquefied carbon dioxide accumulated in the liquid collecting funnel 20 reaches a certain amount, the pressing cylinder 33 will be triggered, and the pneumatic rod will extend and drive the connecting rod 34 to move downward, so that the connecting rod 34 will push the liquid outlet pipe 32 to sink, so that the end of the liquid outlet pipe 32 firmly presses the sealing plug 21, opening the closed state of the sealing plug 21; in this way, the liquefied carbon dioxide can smoothly flow out from the liquid outlet 35 of the liquid outlet pipe 32 and enter the sealing tank 13.

[0036] Please refer to Figure 2 , Figure 7 and Figure 8As shown, a drying component is provided between the carbon dioxide inlet pipe 18 and the liquefaction pipeline 15, and the drying component includes a drying pipeline 41. The carbon dioxide gas flowing in the carbon dioxide inlet pipe 18 can first pass through the drying pipeline 41, undergo necessary drying treatment, and then enter the downstream liquefaction pipeline 15; not only can it ensure that the carbon dioxide is fully dried before entering the liquefaction link, but also can effectively avoid various problems that may arise in the liquefaction process, thereby ensuring the stable operation of the entire system; the carbon dioxide is transported from the carbon dioxide inlet pipe 18 and must first be purified by the drying pipeline 41 to remove impurities such as water vapor that may be contained therein, so that it meets the drying standard required for liquefaction.

[0037] Please refer to Figure 7 and Figure 8 As shown, the drying component also includes a drying filter plate 42. The function of the drying filter plate 42 is to effectively dry the carbon dioxide transported from the carbon dioxide inlet pipe 18. After this drying process, the dehydrated carbon dioxide gas can smoothly enter the liquefaction pipeline 15, and is liquefied through the action of the cooling mechanism 17, thereby ensuring that the final sealed carbon dioxide has a higher purity; in order to ensure that the drying filter plate 42 can function stably, a slot 43 is specially provided on one side of the drying pipeline 41, so that the drying filter plate 42 can be easily plugged in and installed; at the same time, a guide rod 44 is also provided inside the drying pipeline 41, which can position and guide the installation position of the drying filter plate 42; in addition, a handle 45 is also provided on one side of the drying filter plate 42, so that the staff can easily replace and maintain it when necessary, thereby ensuring the continuity and stability of the drying effect.
