Embodiment Construction

[0031] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0032] Such as Figure 1-Figure 7 The shown specific embodiment of a multi-layered resin chromatography column of the present invention includes a columnar shell 3, an upper cover 2 covered on the columnar shell 3 and a base 1 joined to the bottom end of the columnar shell 3; the columnar shell 3 There is a conical resin column cavity 31 with a large upper part and a smaller lower part. A plurality of horizontal arc convex lines 32 are vertically arranged on the inner wall of the resin column cavity 31. A plurality of resin columns 4 are installed in the resin column cavity 31. The column 4 is a cylindrical structure with an open upper end, the lower end surf...

Abstract

The invention belongs to the technical field of chemical medicine extraction equipment, and particularly relates to a multilayer resin chromatographic column which comprises a columnar shell, an uppercover and a base, wherein a big-end-up conical resin column cavity is formed in the columnar shell, a plurality of horizontal arc convex strips are vertically distributed on the inner wall of the resin column cavity, a plurality of resin columns are mounted in the resin column cavity, the lower end faces of the resin columns are porous sieve plates, flanges are arranged at the upper ends of the resin columns, and the flanges are in lap joint with the convex strips to enable the resin columns to be mounted in the resin column cavity; the porous sieve plate of the resin column on the upper layer is butted into the resin column on the lower layer; and the outer diameter of the resin column on the lower layer is smaller than that of the resin column on the upper layer. A quite high resin column in the prior art is divided into a plurality of resin columns which are separated from one another and convenient to take and replace, the resin is not prone to caking or being crushed and damaged,it can be guaranteed that the resin in each layer of resin column is evenly filled, a resin column with inactivated or damaged resin can be flexibly replaced, and convenience and flexibility are achieved.

Description

technical field [0001] The invention belongs to the technical field of chemical and pharmaceutical extraction equipment, and in particular relates to a multi-layer resin chromatography column. Background technique [0002] The separation and purification methods of the effective components of Chinese herbal medicine mainly include macroresin adsorption, water extraction and alcohol precipitation, centrifugation, extraction and membrane separation, etc. Among them, the macroporous resin adsorption technology has the advantages of large adsorption capacity, good selectivity, and easy regeneration. Great advantage. [0003] The liquid medicine is extracted and purified through the chromatographic column equipped with resin. The diameter-to-height ratio of the resin column has a significant impact on the adsorption capacity of the resin. Generally speaking, the smaller the diameter-to-height ratio of the resin, the higher the resin column. , the higher the corresponding adsorpt...
