Abstract
The utility model discloses solvent and heavily steam device, comprise electric jacket, cucurbit, distillation cascade, condenser pipe, condensed fluid collection bottle, cucurbit is placed on electric jacket, it is characterized in that described distillation cascade has two ground ends, two ground ends are connected with cucurbit steam (vapor) outlet end, condenser pipe respectively.The letter of the utility model structure is compact, it is little, easy to loading and unloading quick, effective to take up room; The condenser pipe of two end band grounds, facilitates in practical operation according to the different condenser pipes needing replacing different; The piston-type switch of distillation cascade had both facilitated the collection of condensate liquid, can reduce again the volatilization waste of solvent further, thus ensure the security of experiment.
Description
Technical field
The utility model belongs to distilling apparatus technical field, is specifically related to a kind of solvent and heavily steams device.
Background technology
In natural product chemistry experiment, separation and purification process need uses a large amount of organic solvents, and in order to effective and reasonable utilizes experimental expenses, the technical grade reagent of great majority all after using re-distillation is used for column chromatography eluant, eluent.The principle that solvent heavily steams is the difference utilizing solvent boiling point, heats the solvent of purifying, and after solvent boiling, steam enters into solvent collection bottle through condensing tube condensation, so that needed for experiment.But existing distillation purifying device, be generally made up of distilling flask, condenser pipe, still, solvent receiving bottle, the distilling apparatus of this structure, complex structure, does not have the stand specified to support, assembles cumbersome, and it is comparatively large to take up room, it is very inconvenient that operation uses.
Summary of the invention
For problems of the prior art, the purpose of this utility model is providing that a kind of structure is simple, easy for operation, high efficiente callback, compact conformation solvent distillation purifying device.
The utility model is realized by the following technical programs:
Described a kind of solvent heavily steams device, comprise electric jacket, cucurbit, distillation cascade, condenser pipe, condensed fluid collection bottle, cucurbit is placed on electric jacket, described solvent heavily steams device, it is characterized in that described distillation cascade has two ground ends, ground end is connected with cucurbit steam (vapor) outlet end, condenser pipe respectively.Simultaneously distillation cascade condensate outlet has piston-type switch, when receiving flask fills, can closure piston in case solvent flows out.The more important thing is that condenser pipe adopts two condensation pipe boxes to be added together, improve condensation efficiency, decrease the loss that solvent vapo(u)r causes because condensation is insufficient.
Described solvent heavily steams device, it is characterized in that described cucurbit is two mouthfuls of glass round bottom flask, and it is injection port flatly, is steam (vapor) outlet flatly.
Described solvent heavily steams device, it is characterized in that the two ends of described condenser pipe are ground end.
Described solvent heavily steams device, and it is characterized in that distillation cascade condensate outlet has piston-type switch, controllability is good.
Described solvent heavily steams device, it is characterized in that one-body moldedly on described distillation cascade arranging a branched pipe, and this branched pipe communicates with distillation cascade.
The utility model has the following advantages: structure letter is compact, take up room little, easy to loading and unloading quick, condensation effect is good; The condenser pipe of two end band grounds, facilitates in practical operation according to the different condenser pipes needing replacing different; Condensate outlet has piston-type switch, and controllability is good.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
In figure: 1-condenser pipe, 2-distillation cascade, 3-branched pipe, 4-condensed fluid collection bottle, 5-liquid outlet, 6-cucurbit, 7-electric jacket, 8-injection port.
Detailed description of the invention
Below in conjunction with Figure of description, the utility model is described in further detail, and provides detailed description of the invention.
As shown in the figure, the utility model solvent heavily steams device, comprise the cucurbit 4 be placed on electric jacket 6, the distillation cascade 3 be connected with cucurbit 4, seal be arranged on condenser pipe 2 above distillation cascade 3, distillation cascade 3 piston-type switch connects teflon catheter 5, teflon catheter 5 is connected with liquid-collecting bottle 7.When condensed fluid collection is full, closure piston is only needed to be transferred in suitable vessel by condensate liquid, and without the need to closing whole distilling apparatus.Both simplified the operation, the volatilization of solvent can be prevented again; Two mouthfuls of flasks selected by cucurbit 6, and steam (vapor) outlet end and distillation cascade 2 are tightly connected, and another mouth is injection port, and when needing to add solvent in cucurbit 6, the piston only need opening injection port conveniently can add solvent; Without the need to unloading cucurbit 6, time saving and energy saving; The two ends of condenser pipe 1 are ground end, and the setting of this kind of structure avoids and takies larger space, can reach good condensation effect again; On distillation cascade 3, be also provided with a branched pipe 8 in addition, this branched pipe 8 and the one-body molded setting of distillation cascade 2, the setting of branched pipe 8 both can play the effect of fixing whole device, can shunt a part of solvent vapo(u)r again, reached object of better purifying.
The course of work, open electric jacket 6, regulate heating-up temperature to the boiling point being purified solvent, be purified solvent in cucurbit 4 by thermal evaporation, solvent vapo(u)r enters condenser pipe 1 through distillation cascade 3 and branched pipe 8, flow in condensed fluid collection bottle 7 at condenser pipe 1 post liquefaction through polytetrafluoro conduit 5, condensed fluid collection bottle 7 is collected to a certain degree, the receiving bottle that the piston of closing distillation cascade 3 renews again.
Claims (5)
