Description

Technical Field

[0001] This utility model relates to the field of gas production and utilization technology, specifically to a filling device for a mixture of argon and carbon dioxide gas. Background Technology

[0002] In existing technologies, the argon and carbon dioxide gas filling process usually involves preparing a full carbon dioxide cylinder based on a sales order, then filling the carbon dioxide cylinder into an argon + carbon dioxide mixed cylinder according to a certain ratio. After filling, each cylinder is weighed, and finally argon is added to the specified pressure. This operation is quite wasteful of manpower and resources.

[0003] Chinese patent (publication number: CN207132089U) discloses a high-pressure mixed gas filling system device, which includes a liquid argon storage tank, a cryogenic liquid carbon dioxide storage tank, a liquid cryogenic pump, a high-pressure vaporizer, and a filling line. The liquid argon storage tank is connected to the liquid cryogenic pump, which is connected to the high-pressure vaporizer. The high-pressure vaporizer and the cryogenic liquid carbon dioxide storage tank are connected in parallel and then connected to the filling line. A branch pipeline is connected between the parallel connection point of the high-pressure vaporizer and the cryogenic liquid carbon dioxide storage tank and the filling line, and this branch pipeline is connected to the liquid cryogenic pump. The filling line is connected to a high-pressure cylinder. An online purity analysis device is installed on the high-pressure vaporizer and the branch pipeline connected to the liquid cryogenic pump. A pressure alarm control device is installed on the cryogenic liquid carbon dioxide storage tank and the branch pipeline connected to the liquid cryogenic pump. In the above patent document, the liquid argon storage tank is connected in parallel with the cryogenic liquid carbon dioxide storage tank after passing through the high-pressure vaporizer and then connected to the filling line. When filling the cylinder, the ratio of argon to carbon dioxide content is difficult to control. Utility Model Content
