[0002] Carbon dioxide separation membrane refers to a gas separation membrane that can separate carbon dioxide from a mixed gas. Carbon dioxide is a condensable gas with strong polarization. Its solubility coefficient in membrane materials is relatively large, so its permeability coefficient and separation coefficient are also relatively large. Generally, almost all membrane materials with good oxygen permeability can be used to separate carbon dioxide with oxygen-enriched membranes. In the production of CO2 separation membranes, it is necessary to use a proportioning device to produce liquid raw materials and physical raw materials through formula proportioning. A good proportioning device can reduce the difficulty of proportioning and bring convenience to users.

After the raw liquid of the entire CO2 separation membrane is proportioned, the physical material in the raw liquid and the liquid material in the raw liquid are mixed and stirred in the form of oscillation by the vortex mixer 4. Compared with stirring with a stirring shaft, this oscillating mixing method can reduce the possibility of contamination by the stirring shaft during mixing, resulting in the possibility of the appearance of impurities, thereby improving the purity of the raw liquid and meeting the subsequent CO2 separation membrane In order to meet the production requirements and ensure that the mixing tank 5 can effectively mix and stir, a limiting anti-skid ring 43 is attached to the connection between the mixing tank 5 and the mixing bed 42, and the limiting anti-skid ring 43 and the mixing tank 5 are interference fit to ensure that the mixing tank 5 will not tilt and collapse during the oscillation process, thereby ensuring the safety of the entire CO2 separation membrane production, and the outer diameter of the eccentric hole 51 on the mixing tank 5 is larger than the outer diameter of the discharge pipe 34, which can ensure that when the mixing tank 5 oscillates, there is a certain reserved space to ensure that the discharge pipe 34 is always discharging materials, while reducing the contact between the mixing tank 5 and the discharge pipe 34, thereby reducing the possibility of hard damage.

[0023] The feeding pipe 33 is distributed with a slight inclination, and the inclination angle of the feeding pipe 33 is 5-10°.
