Accompanying drawing 1 is the utility model one embodiment sectional structure schematic diagram.
Accompanying drawing acceptance of the bid keep the score state as follows: the 1-passage; The 2-water bath with thermostatic control; 3-guiding fluid plate; 4-V type feeder: 5-drop pipe; The 6-inner core; The 7-magnetic valve; The 8-support; The 9-waste discharge slot; The 10-control valve; 11-water-bath water inlet; 12-water-bath delivery port; The 13-top cover; The 14-clip; The 15-flowmeter; 16-light-inductive device; The 17-drain hole; The 18-urceolus; The 19-benzinum; The 20-electric boiling plate; The 21-base; 22-dividing plate with holes.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.As shown in Figure 1, urceolus 18 is the cylinder of a stainless steel, the inner core 6 of a built-in identical material, and outer tube bottom has electric boiling plate 20.Benzinum 19 is poured into the urceolus 18 from top, cover top cover 13 after, be heated back volatilization of benzinum 19, the water bath with thermostatic control 2 that runs into top is condensed into liquid and splashes in the V-type feeder 4 along guiding fluid plate 3, splashes into inner core 6 through flowmeter 15.When the volume of the benzinum that splashes into reaches the setting value of accurate calculating, the magnetic valve 7 of tube bottom was opened in light-inductive device 16 on inner core 6 outer walls will be controlled, benzinum flows to urceolus through drain hole 17, when the volume of inner core benzinum was lower than light-inductive device 16 controlling values, magnetic valve 7 cut out drain hole 17 automatically.Whether electric boiling plate 20 heats by flowmeter 15 controls, and behind the flow that reaches setting, electric boiling plate 20 stops heating automatically.The control valve 10 on top can be opened according to the test needs.Top cover 13 be placed on urceolus 18 suitable for reading on, by clip 14 they are fixed together, open clip 14, this extractor can be divided into two parts.Top cover 13 is opened, sample can be put into, and can add quantitative benzinum, after experiment is finished, the benzinum that gives up can be discharged by waste discharge slot 9, and clean inner core 6 and urceolus 18.
When carrying out extraction test, operate according to the following steps with the utility model:
The first step is put into glass with load weighted sample and is soaked the extracting tube, and drying is 2 hours in 80 ± ℃ baking oven, after the taking-up, puts into drier cooling 30 minutes immediately, accurately weighs.Extractor top clip 14 is opened, the some glass that weigh up are soaked the benzinum that the extracting tube is gone in the inner core 6 and poured set amount into, cover extractor top cover 13, the clip 14 that closes is shut control valve 10, standing over night.
Second step, extractor top cover 13 is opened, in urceolus 18, add the benzinum 19 of zeolite and set amount, cover top cover 13, the clip 14 that closes is opened top control valve 10 to 1/3rd, turn on the power switch, open water bath with thermostatic control 2, according to calculating and setting flowmeter numerical value.The electric boiling plate 20 of extractor bottom begins heating, evaporation after benzinum 19 in the extractor urceolus 18 is heated, rise to extractor top cover 13 by dividing plate 22 with holes, run into water bath with thermostatic control 2 after, condensation water along guiding fluid plate 3 residual titrations to V-type feeder 4, splash into inner core 6 through fluid flowmeter, temperature is high more, and speed is fast more, reach the amount of setting of flowmeter 15 when withdrawing fluid after, electric boiling plate 20 quits work, to keep flowmeter numerical value constant.When being lower than this value, electric boiling plate 20 work move in circles.
In the 3rd step, when the amount of fluid of extractor inner core 6 reaches a certain amount of, be arranged on light-inductive device 16 work on inner core 6 walls, the magnetic valve 7 of interlock inner core 6 bottom drain holes 17, drain hole 17 is opened, and the benzinum of inner core 6 is drained into urceolus 18, to realize the purpose of continuous extracting.Can add from the passage 1 on top when needing in the experimentation to replenish benzinum, standard-sized sheet control valve 10 gets final product.
In the 4th step, experiment is opened extractor top cover 13 after finishing, and takes out the extracting tube that sample is housed, and puts into 80 ± ℃ baking oven after sample is volatilized naturally dry 2 hours, puts into drier after the taking-up at once, cools off 30 minutes, accurately weighs.The waste discharge slot 9 of bottom is opened in off-test, discharges benzinum, and cleans entire equipment.
The utility model has popularizing application prospect at the tobacco chemistry analysis field, at chemical analysis, particularly also has popularizing application prospect in food, the beverage analysis field.
