Abstract
The utility model provides an artemisia apiacea extracting device comprising an extraction tank, a condenser, an evaporator and an extraction liquid storage tank, the top of the extraction tank is connected with one end of the condenser, the lower end of the extraction tank is connected with a bleeder valve, the bleeder valve is connected with the evaporator by a closed pipeline, the top of the evaporator is connected with the top of the extraction tank by the closed pipeline, and the bottom of the evaporator is connected with the extraction liquid storage tank. The artemisia apiacea extracting device extracts for six hours same as the original process, while the extracting times are increased, so that the effective components can be extracted completely, the resources are saved, the solvent using amount is reduced by 42.8%, the solvent consuming amount is reduced; and the solvent is put at one time, so that the operation is simplified; and due to the use of the device, the extraction efficiency is improved by 23.7%.
Description
Technical field
The utility model relates to a kind of extraction element of sweet wormwood.
Background technology
Artemisinin-based drug is one big type the most commonly used in the antimalarial agent, and it is that China at first finds and manufactures.The method for preparing artemisinin-based drug commonly used mainly contains organic synthesis and carries out separation and Extraction through the sweet wormwood raw material.To the method for distilling of sweet wormwood, domestic production producer produces qinghaosu with hot formulation.This method is in existing common extractor, to carry out three times to extract, and solvent load is big, and the post processing workload is big, and loss is also bigger.
The utility model content
The purpose of the utility model is to provide a kind of sweet wormwood extraction element, can reduce the consumption that extracts solvent, and improves extract yield.
The utility model provides a kind of sweet wormwood extraction element; It comprises extractor, condenser, evaporimeter, extract basin; The top of extractor links to each other with an end of condenser, and the lower end is connected with bleeder valve, through closed conduit bleeder valve is linked to each other with evaporimeter; The top of evaporimeter links to each other with the top of extractor through closed conduit, and the bottom of evaporimeter links to each other with the extract basin.
Wherein, the horizontal level of evaporimeter is lower than extractor.
Wherein, the other end of condenser also is provided with cooler and oil water separator.
The utility model and former technology were extracted in same 6 hours, but had increased extraction time, and effective ingredient is extracted fully, had practiced thrift resource, and solvent load reduces 42.8%, has reduced solvent consumption; The solvent one feeding has been simplified operation; Use this device can improve recovery rate 23.7%.
Description of drawings
The structural representation of Fig. 1 the utility model;
Wherein, 1-extractor, 2-condenser, 3-cooler, 4-evaporimeter, 5-oil water separator, 6-bleeder valve, 7-change valve, 8-water inlet, 9-draining, 10-emptying, 11-vacuum, 12, steam, 13-extract basin.
The specific embodiment
As shown in Figure 1, the utility model is a kind of sweet wormwood extraction element, and it comprises extractor 1, condenser 2, evaporimeter 4, extract basin 13; The top of extractor 1 links to each other with an end of condenser 2; The lower end is connected with bleeder valve 6; Through closed conduit bleeder valve 6 is linked to each other with evaporimeter 4, the top of evaporimeter 4 links to each other with the top of extractor 1 through closed conduit, and the bottom of evaporimeter 4 links to each other with extract basin 13; The horizontal level of evaporimeter 4 is lower than extractor 1; The other end of condenser 2 also is provided with cooler 3 and oil water separator 5.
In actual mechanical process, add sweet wormwood in the extractor 1, add 5 times of solvents again; Add 3 times of solvents in the evaporimeter 4, heat solvent in two jars simultaneously, waiting to reflux begins to regulate two jars of temperature; When the extractor liquid level rises to assigned address, open bleeder valve 6, extract is put into evaporimeter; After having closed bleeder valve 6, suitably reduce the extractor temperature, the rising evaporator temperature; Make solvent gasification inflow extractor or get back to extractor, when treating that solvent liquid level is raised to assigned address, put into evaporimeter through the condensation of extractor overhead condenser.Repeatable operation guarantees it is that fresh solvent extracts the effective ingredient in the sweet wormwood at every turn, extracts and carries out 6 hours, and extract is collected in the evaporimeter and emits.Cross silica gel column chromatography, wash-out, concentrate, crystallization, refining finished product (pilot-scale experiment is seen table 1).
Have hot formulation technology (former technology) now as follows:
Get a certain amount of sweet wormwood and add in the extractor, divide three times and add 5,5,4 times of solvents, extracted 3,2,1 hours in 65 ℃.Collect No. three times extract, cross silica gel column chromatography, wash-out, collect the eluent that contains qinghaosu, concentrate, crystallization, operation such as refining get finished product (pilot-scale experiment is seen table 2).
The result shows that the utility model and former technology were extracted in same 6 hours, but had increased extraction time, and effective ingredient is extracted fully, has practiced thrift resource, and solvent load reduces 42.8%, has reduced solvent consumption; The solvent one feeding has been simplified operation; Use this device can improve recovery rate 23.7%.
