Description
Technical field
The utility model is related to a kind of drug production equipment, especially a kind of chromatographic column.
Background technology
Chinese medicine isolates and purifies at present, mainly uses chromatographic column, is realized by column chromatography procedure.Chromatographic column carries out column
When chromatographic runs, first target components are unfolded in pillar, according to the affine degree of target components and filler and solvent, mesh
Mark component is positioned in the different location in pillar, realizes initial gross separation, is then eluted target components one by one using eluant, eluent
Out, being kept completely separate for target components is realized.But when isolating and purifying of Chinese medicine is being carried out using chromatographic column at present, often it will appear
Traditional Chinese medicine ingredients are lumpd in chromatographic column, and then cause eluant, eluent to be eluted when needs a large amount of eluant, eluent, and elute effect
Rate is low, and elution effect is also undesirable.The use of a large amount of eluant, eluents also increases subsequent concentrated cost simultaneously.
Utility model content
The purpose of the utility model is to provide a kind of chromatographic columns.The utility model has eluent dosage low, elution effect
Rate is high, the elution feature that effect is good and subsequent concentration is at low cost.
The technical solution of the utility model：The top of a kind of chromatographic column, including cylinder, cylinder is equipped with dome, divides on dome
It She You not liquid inlet and gas outlet；It is equipped with level-one sieve plate in cylinder, blowning installation, blowning installation lower section are equipped with below level-one sieve plate
Equipped with two level sieve plate, liquid outlet is equipped with below two level sieve plate；The blowning installation includes that ellipse divides crust of weathering body, ellipse to divide the crust of weathering
Venthole is distributed in the top surface of body, and ellipse, which divides, is equipped with gas-guide tube in crust of weathering body, gas-guide tube is connected to air inlet pipe, gas-guide tube lower part
Tube wall, which is equipped with, divides general mood hole；The ellipse divides the bottom of crust of weathering body also to be connect with liquid inlet through recycling liquid pipe.
In chromatographic column above-mentioned, a diameter of 0.1-1 μm of the sieve pore of the two level sieve plate.
Advantageous effect
Compared with prior art, blowning installation is arranged in the utility model in chromatographic column, and blowning installation includes that ellipse divides wind
Shell, ellipse divide the top surface of crust of weathering body that venthole is distributed with, and ellipse, which divides, is equipped with gas-guide tube in crust of weathering body, gas-guide tube connects with air inlet pipe
Logical, the tube wall of gas-guide tube lower part, which is equipped with, divides general mood hole；With this configuration, it when carrying out column chromatography, is first blown into centainly to cylinder
The air of pressure dispels the traditional Chinese medicine ingredients of caking, keeps contact of the traditional Chinese medicine ingredients with eluant, eluent more abundant, and elution effect is more preferable,
Eluting agent is also reduced, elution efficiency is improved, reduces subsequent concentration cost.The blowning installation of the utility model be
Ellipse, which divides, is arranged gas-guide tube in crust of weathering body, ellipse divides the top surface of crust of weathering body that venthole is distributed with, set on the tube wall of gas-guide tube lower part
There is a point general mood hole；With this configuration, divide general mood hole to be on the tube wall of gas-guide tube lower part (as shown in Figure 3), can effectively subtract
The blocked risk of small gas-guide tube, improves device reliability of operation.
To sum up, the utility model has eluent dosage low, and elution efficiency is high, and elution effect is good and subsequent concentration is at low cost
The characteristics of.

Specific implementation mode
The utility model is further described with reference to the accompanying drawings and examples, but is not intended as to the utility model
The foundation of limitation.
Embodiment 1.A kind of chromatographic column, as shown in Figs. 1-3, including cylinder 1, the top of cylinder 1 are equipped with dome 2, on dome 2
It is respectively equipped with liquid inlet 8 and gas outlet 9；Level-one sieve plate 3 is equipped in cylinder 1,3 lower section of level-one sieve plate is equipped with blowning installation 4, blows
4 lower section of device is equipped with two level sieve plate 5, and 5 lower section of two level sieve plate is equipped with liquid outlet 6；The blowning installation 4 divides the crust of weathering including ellipse
Body 41, ellipse divide the top surface of crust of weathering body 41 that venthole 42 is distributed with, and ellipse, which divides, is equipped with gas-guide tube 43, gas-guide tube 43 in crust of weathering body 41
