Abstract

The invention provides a double-station spraying nozzle. Through cooperation of an inner piston and an outer piston of the double-station spraying nozzle, a spraying nozzle semi-opened station and a spraying nozzle completely-opened station can be realized. Through the double-station spraying nozzle provided by the invention, the problem of low gel-filling and cleaning efficiency for a spraying nozzle only with a station in a related art is solved, and the gel-filling and cleaning efficiency of a chromatographic column is improved.

Description

technical field [0001] The invention relates to the field of industrial separation and purification, in particular to a dual-station spray head for chromatography columns. Background technique [0002] Chromatographic column is the main body of gel chromatography technology, and it is generally required to complete the entire aseptic operation of the solution in a clean aseptic workshop. Therefore, it is particularly important to avoid human intervention and improve the automation of chromatography; [0003] Through the lifting (opening and closing) of the nozzle of the chromatography column, the processes of loading, unloading, and cleaning can be completed; in the prior art, the nozzle of the chromatography column has only one opening and closing station, that is, when the nozzle rises, it opens, Closed when descending. The nozzle with only one station leads to multiple lifting and lowering during glue loading and cleaning, so the efficiency is not high. Contents of the...
