Description

Technical Field

[0001] The utility model relates to the technical field of storage, in particular to a high-sealing storage tank for cephradine stock solution. Background Art

[0002] The preparation efficiency and purity of cefradine are greatly affected by the purity of the cefradine stock solution. Therefore, ensuring that the cefradine stock solution in the storage process and storage tank is not contaminated is the most important point in the storage of cefradine stock solution.

[0003] For example, a Chinese patent discloses "a high-temperature anti-corrosion storage tank" (patent number: CN112009895B), which includes a tank body, a bottom cover, and a storage bin. The upper end of the tank body is provided with a storage bin, and the lower end of the storage bin is provided with a bottom cover. The side wall of the tank body is sleeved with a lifting structure, and the lifting structure includes a first circular ring, a first protrusion, a protective cover, a mounting groove, a hydraulic cylinder, a plug, a buffer pad, a second circular ring, and a second protrusion. The side wall of the first circular ring is provided with a first protrusion, and the lower end of the first protrusion is provided with a protective cover. The protective mounting structure is provided with a mounting ring, an elastic ring, and a protrusion. The elastic ring can be stretched and expanded. The elastic ring and the mounting ring protect the upper end component of the sealing top cover, and the mounting ring facilitates the fixed installation of other components of the top cover. The above patent has the advantage of restricting the buffer support structure.

[0004] However, the above storage process is not suitable for the storage of cephradine stock solution because the liquid is easily in contact with air when it is poured into the storage tank. The cephradine stock solution is easily oxidized by air or replaced with impurities in the air. Utility Model Content
