[0023] A liquefied cylinder 1, a pressurized cylinder 2 is connected to the right side of the liquefied cylinder 1, and a piston 3 is arranged inside the pressurized cylinder 2, a connecting rod 4 is connected to the center of the right end of the piston 3, and a pulling rod 5 is connected to the right end of the connecting rod 4, an air inlet pipe 16 is connected to the top of the liquefied cylinder 1, and a liquid collecting tank 14 is connected to the bottom of the liquefied cylinder 1, a rotating disk 6 is connected to the right end of the pulling rod 5, and the rear end center of the rotating disk 6 is connected to the output end of the motor 7, and the motor 7 is fixed on the liquid collecting tank 14, a valve plate 12 is arranged on the top and bottom of the liquefied cylinder 1, and the valve plate 12 monomers are connected to the liquefied cylinder 1 through springs 13, a mounting plate 11 is arranged on the left side of the liquefied cylinder 1, and a refrigeration pipe 9 is installed on the mounting plate 11;

[0024] The refrigerator 8 is arranged on the left side of the liquefier cylinder 1 , and the refrigerator 8 is connected to the refrigeration pipe 9 through the connecting pipe 10 .

[0025] like Figure 1 and Figure 2 The liquefaction cylinder 1 and the pressure cylinder 2 are integrated, and the piston 3 and the pressure cylinder 2 form a sliding structure, which is convenient for applying pressure to the liquefaction cylinder 1. The pulling rod 5 is rotationally connected to the connecting rod 4, and the pulling rod 5 is eccentrically rotationally connected to the rotating disk 6. The rotating disk 6 forms a transmission mechanism with the piston 3 through the pulling rod 5 and the connecting rod 4, which is convenient for driving the piston 3 to slide.

[0026] like Figure 2 and Figure 3 The middle mounting plate 11 is fixedly connected to the liquefier cylinder 1 by bolts, and the refrigeration tube 9 on the mounting plate 11 is arranged in a spiral structure, which is convenient for cooling the inside of the liquefier cylinder 1, and the valve plate 12 is arranged in a "convex" structure, and spring pieces 13 are arranged at equal angles on the outside of the valve plate 12, which is convenient for ensuring the stable operation of the valve plate 12, and an observation window 15 is arranged in the middle of the liquid collecting box 14, and the observation window 15 is a transparent structure, which is convenient for viewing the liquefaction situation.

[0027] Working principle: When using the carbon dioxide liquefaction device, Figure 1 As shown, the gaseous carbon dioxide after purification and drying is connected to the air inlet pipe 16, and by starting the motor 7, the motor 7 drives the rotating disk 6 to rotate, and the rotating disk 6 is eccentrically connected to the pulling rod 5, so that when the rotating disk 6 rotates, the pulling rod 5 can be pulled to move, and the pulling rod 5 is rotatably connected to the connecting rod 4, so that the pulling rod 5 drives the piston 3 to slide in the pressurizing cylinder 2 through the connecting rod 4;

[0028] When piston 3 slides to the right, Figure 3 As shown, the piston 3 draws the gas in the liquefied cylinder 1 through the pressurizing cylinder 2, so that the valve plate 12 on the top of the liquefied cylinder 1 moves downward, so that the air inlet pipe 16 is connected with the liquefied cylinder 1, which is convenient for carbon dioxide to enter the liquefied cylinder 1 through the air inlet pipe 16. At the same time, the valve plate 12 below the liquefied cylinder 1 is subjected to suction, and the liquefied cylinder 1 is disconnected from the liquid collecting tank 14, thereby preventing the gas in the liquid collecting tank 14 from entering the liquefied cylinder 1. When the piston 3 slides to the left, the piston 3 applies pressure to the liquefied cylinder 1 through the pressurizing cylinder 2, compresses the carbon dioxide gas in the liquefied cylinder 1, and makes the valve plates 12 on the upper and lower sides of the liquefied cylinder 1 move in the opposite direction, disconnects the air inlet pipe 16 from the liquefied cylinder 1, and connects the liquid collecting tank 14 with the liquefied cylinder 1, which is convenient for the carbon dioxide in the liquefied cylinder 1 to enter the liquid collecting tank 14. The spring plate 13 on the valve plate 12 facilitates the operation of the valve plate 12.

[0029] like Figure 3 As shown, the refrigeration tube 9 in the liquefied cylinder 1 is connected to the refrigerator 8 through the connecting tube 10, so that the cold air generated by the refrigerator 8 can enter the interior of the liquefied cylinder 1, thereby facilitating the cooling of the carbon dioxide and thus facilitating the liquefaction of the carbon dioxide. The reciprocating sliding of the piston 3 compresses the carbon dioxide and cools it into the liquid collecting tank 14 to complete the liquefaction production. The observation window 15 on the liquid collecting tank 14 is convenient for viewing the liquefaction situation. This is the entire working process of the carbon dioxide liquefaction device.
