Movable beam type full-automatic chromatographic column

Abstract

The invention discloses a movable beam type full-automatic chromatographic column which is provided with a door type support, wherein a detachable column tube is arranged in the door type support, a column head which can move up and down is arranged in the column tube, a screen assembly is arranged at the lower part of the column tube, an upper pneumatic spray head for adding fillers is arranged on the column head, and a lower pneumatic spray head for discharging the fillers is arranged at the lower part of the screen assembly; an upper filler inlet, a chromatographic opening and a cleaning opening are respectively formed in the upper part and the lateral side of the upper pneumatic spray head; an upper beam of the door type support can move up and down, a driving mechanism is connected tothe door type support, the driving mechanism is connected with the upper beam, the upper beam is connected with the column head, the column head can be driven by the beam to move up and down, and thecolumn tube can be driven by the upper beam to move upwards when being cleaned. The movable beam type full-automatic chromatographic column is provided with a control device, and the driving mechanism and the upper pneumatic spray head are respectively connected with the control device electrically and pneumatically. The movable beam type full-automatic chromatographic column disclosed by the invention has the characteristics of small volume and space occupation, full-automatic control, high cleaning efficiency, good cleaning effect, convenience in installation and use and the like.

Description

【Technical field】 [0001] The invention relates to chromatographic equipment, in particular to a moving beam type automatic chromatographic column which is small in size, easy to clean, high in column efficiency and stable in processing performance. 【Background technique】 [0002] Chromatography is a gel separation method, typically silica gel chromatography. It is separated by reacting the separation fluid with the gel in the chromatographic column through molecular sieve, ion exchange, etc. Chromatographic column is the main body of gel chromatography technology, generally using glass tube or plexiglass tube, which is filled with gel, and equipped with fluid distribution plate and sieve plate at both ends. The traditional chromatography column is driven by a central screw to move the column head up and down, so it needs a large longitudinal space for the screw to move, and because the screw is connected to the disc-shaped body with the nut, and passes through several exter...

AI Technical Summary

Problems solved by technology

The traditional chromatography column is driven by a central screw to move the column head up and down, so it needs a large longitudinal space for the screw to move, and because the screw is connected to the disc-shaped body with the nut, and passes through several external The connecting column is connected with the column head, so that the force of the screw on the disc-shaped body acts on the center of the disc-shaped body, causing the disc-shaped body to be easily deformed when it is subjected to the action of the screw

When it is necessary to clean the screen, it is necessary to remove the cylinder located between the upper and lower screens before cleaning the screen, and the process of removing the cylinder is complicated, and the removed cylinder will occupy the horizontal space. Space, so that the entire chromatography column equipment requires large vertical and horizontal space for setup and operation
