Abstract
The utility model relates to an analytic instrument used to extract soluble substances from solids, belonging to the class of chemical analytic instruments. A universal soxhlet extractor at home and abroad comprises a spherical or spiral condenser, a straight cylinder shaped extractor, etc., having the defects of long time extraction, complex operation, and large hydroelectric consumption. The utility model adopts a jacketed extractor and a pipe bundle condenser, and a siphon pipe is arranged in the extractor. When the utility model works, with samples and condensed solvents stirred by a stirrer and preheated by the solvent vapor passing through the sandwich layer, the dissolution speed of the soluble substances in solid samples is increased, the extracting time is shortened, the hydroelectric power consumption is saved, and the analysis is instrumented.
Description
The present invention relates to from solid, extract the analytical instrument of soluble substance, belong to the chemical analysis instrument class.
At present, the soluble substance that extracts both at home and abroad in the solid mostly adopts soxhlet extraction, and it is made up of sphere or coil condenser, straight tubular extractor and flat flask.Fig. 1 is the extraction device schematic diagram of existing Soxhlet method.The solvent heating and gasifying of packing in the boiling flask 4, rise to condensation liquefaction in the ball condenser 1 by arm 5, splash in the solid sample in the straight tubular extractor 2, at this moment, soluble substance in the solid is dissolved separates out, and when the liquid level that is dissolved with soluble substance liquid surpasses the height of siphon pipe 3, can be back in the boiling flask 4 automatically, through circulation repeatedly for a long time, the soluble substance in the solid can be separated.
The weak point of this method for extracting is: the extracting time is long, complex operation, and hydroelectricity consumption is big.
Deficiency at above the objective of the invention is: improve extraction efficiency, shorten the extracting time, the analysis operation instrumentation.
Design a kind of instrument, Fig. 2 is the structural representation of this instrument.The transmission system 1 of this instrument places on the upper plate 2, with metal mainstay 3,4,13,14 upper plate 2 and base 15 is coupled together.Boiling flask 10 is placed in the thermostat water bath 11, with chuck extractor 12, pipe bundle condenser 6, and handtailor bearing 5,8 connections, place framework, form and stir the extracting instrument.Fig. 3 is the structural representation of pipe bundle condenser 6, and Fig. 4 is the structural representation of chuck extractor 12.Agitator 9 is by the transmission of axle 7 in chuck extractor 12, can be in filter cylinder stirred sample ceaselessly.
The invention is characterized in: have the chuck 23 that to walk solvent vapo(u)r in the chuck extractor 12, (shown in Figure 4).Siphon pipe 24 places in the chuck 23, and the upper end of chuck internal layer is furnished with several air admission holes 22; Pipe bundle condenser 6 is by on two dividing plates 16 up and down and 19 of several tubule 20 sintering arranged side by side in cylindrical shell 18, (as shown in Figure 3).Two interfaces 17,21 of turnover cooling water place the both sides on condenser cylindrical shell 18 tops.
Following the present invention embodiment in 2 in conjunction with the accompanying drawings is described in detail: the solvent in the boiling flask 10 becomes steam after being heated in thermostat water bath 11, enter condensation liquefaction in the tubule 20 in the pipe bundle condenser 6 by chuck 23 and internal layer air admission hole 22, splash in the solid sample in the chuck extractor 12, sample and condensing solvent through the chuck solvent vapo(u)r heat, in the pipe bundle condenser 6 in shaft 7 and the chuck extractor 12 agitator 9 constantly stir and extract circulating reflux effect repeatedly, the soluble substance in the solid can be extracted out rapidly.
The present invention compared with prior art has following advantage: the extraction efficiency height, and technique effect is good, and is easy and simple to handle, and analytical instrument can be saved a large amount of water power.
