[0002] Argon and carbon dioxide mixed gas filling equipment is a specialized device used to mix argon and carbon dioxide in a specific ratio and safely and efficiently fill the mixture into gas cylinders. Its core function is to meet the demand for precisely proportioned mixed gases in industrial production, and it is widely used in welding, metal processing, and other fields.

[0003] Currently, existing argon and carbon dioxide mixed gas filling processes have several problems. For example, the traditional method typically involves preparing pre-filled carbon dioxide cylinders based on sales orders, then filling them into argon and carbon dioxide mixed cylinders in a specific ratio. After filling, each cylinder must be weighed, and finally, argon is added to the specified pressure. This method is not only labor-intensive and resource-intensive, but also inefficient and produces inconsistent filling quality. Furthermore, some existing equipment does not achieve good gas mixing during the filling process. Utility Model Content

An impeller 11 is fixedly connected to the rod wall of the rotating rod 9. Mounting plates 12 are fixedly connected to both outer walls of the mixing chamber 6. Several guide plates 23 are installed on the inner wall of the mixing chamber 6. Guide blocks 24 are fixedly connected to the four corners of the mixing chamber 6 to guide the gas, allowing the gas to contact and mix more fully with the impeller 11. The two mounting plates... The inner wall of the 12 is fixedly connected to the guide pipe 13. The bottom inner wall of the mixing box 6 is provided with a conveying pipe 14 that communicates with the guide pipe 13.

[0024] The working principle of this utility model is as follows:

[0025] First, liquid argon is transported from liquid argon storage tank 3 through argon filling pipeline 7, and cryogenic liquid carbon dioxide is transported from cryogenic liquid carbon dioxide storage tank 4 through carbon dioxide filling pipeline 8. During the transportation process, the two gases are first converted from liquid to gas by vaporizer 19, and then the pressure is adjusted to the working pressure of the mixing tank 6 by pressure reducer 20 to ensure that the gas enters the mixing tank 6 stably. The control valve 18 on the pipeline is precisely controlled by PLC controller 22 to strictly control the inflow of the two gases and ensure that they are mixed in the preset ratio. At this time, the geared motor 10 is started. The output end of the geared motor 10 drives the rotating rod 9 to rotate, which in turn drives the impeller 11 to rotate, strongly stirring the two gases. At the same time, the guide plate 23 and guide block 24 in the mixing tank 6 guide the gas flow direction, so that the gas fully contacts and mixes evenly. The evenly mixed gas enters the guide pipe 13 through the delivery pipe 14, and then is distributed to multiple gas cylinders 16 through the filling manifold 17.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
