Abstract
The utility model relates to the technique field of extraction equipment, in particular to a Soxhlet extractor, which comprises an extraction flask, an extraction tube and a condenser. The extraction flask, the extraction tube and the condenser are sequentially communicated with each other. The extraction tube is equipped with a return tube and a connecting tube. A filtering layer is arranged in the extraction tube. A fixing belt is arranged at the connection part of the extraction flask and the extraction tube. The filtering layer is arranged at a distance of one third of the height of the extraction tube from the bottom of the extraction tube, so that the detection error of the extractive caused by backflow is reduced without affecting the extraction rate. The fixing belt is arranged at the connection part of the extraction flask and the extraction tube, so that the extraction tube is effectively prevented from being pushed away from the extraction flask due to the too high pressure in the extraction flask. The Soxhlet extractor is reasonable in structure, convenient in operation and easy in obtaining materials and will not increase the burden of conventional equipment, thus is suitable for being popularized and applied in a large range.
Description
Technical field
The utility model relates to the extraction equipment technical field, especially a kind of apparatus,Soxhlet's.
Background technology
Existing apparatus,Soxhlet's in use; The fiber fines that contains in some sample is back in the flask with extracting liquid out easily, and this is back in the flask because fiber fines proportion is very little so be suspended in easily in the solvent; And do not have filter in the existing extractor; Can not filter Extract, thereby cause testing result to produce error, result's the degree of accuracy is measured in influence.The apparatus,Soxhlet's of using in the practice at present often may back down extraction tube because the extractor internal pressure is too high in flask, cause the failure of an experiment or other accidents, and the harm personal safety causes the wasting of resources.
The utility model content
The purpose of the utility model is can't filter fiber fines and use unsafe defective in order to overcome existing apparatus,Soxhlet's, and a kind of apparatus,Soxhlet's is provided.
The technical scheme that the utility model technical solution problem adopts is: a kind of apparatus,Soxhlet's; Comprise extraction flask, extraction tube and condenser; The three is communicated with successively; Also be provided with return duct and connecting tube on the extraction tube, be provided with filter course in the said extraction tube, the junction of said extraction flask and extraction tube is equipped with fixed band.
Said filter course is arranged at 1/3rd places, extraction tube bottom.
Said filter course bore dia is 10～50% μ m.
Said extraction flask is a round-bottomed flask.
The beneficial effect that the utility model had is:
In the extraction tube set inside filter course, under the prerequisite that does not influence extracting speed, the error when having reduced the detection extract that causes because reflux; The fixed band that install the junction of extraction flask and extraction tube can effectively prevent in extraction flask, to back down extraction tube the utility model reasonable in design because of the extraction flask internal pressure is too high; Easy to operate; Can not increase the burden of existing equipment, draw materials easily, be fit to apply on a large scale.
Description of drawings
Accompanying drawing is the structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done following detailed description.
As shown in the figure; The utility model comprises extraction flask 1, extraction tube 2 and condenser 3, and the three is communicated with successively, also is provided with return duct 5 and connecting tube 4 on the extraction tube 2; It is characterized in that: be provided with filter course 6 in the said extraction tube 2, the junction of said extraction flask 1 and extraction tube 2 is equipped with fixed band 7; Said filter course 6 is arranged at 1/3rd places, extraction tube 2 bottoms; Said filter course 6 bore dias are 10～50 μ m; Said extraction flask 1 is a round-bottomed flask.
The pure Dichloromethane of condenser 3 cooling evaporations is back in the extraction tube 2 cooled Dichloromethane, with lipid, the benzene class material of the effective contact lysis sample of sample; The Dichloromethane phegma of extraction tube 2 splendid attire samples and cooling; Extraction flask 1 dress Dichloromethane and extract; Return duct 5 utilizes siphon principle, is dissolved in the matter in the Dichloromethane extracting out in the sample, is back in the extraction flask 1; Connecting tube 4 pure Dichloromethane steam (vapor) outlets send condensation in the condenser 3; Filter course 6 filters fiber fines and impurity; The fixed band 7 that install the junction of extraction flask 1 and extraction tube 2 can prevent in extraction flask, to back down extraction tube because of the extraction flask internal pressure is too high.
