Background technique

Distillation and condensation are a kind of isolation technics between a kind of solid being in daily use, liquid or liquid, liquid, especially In the recycling of solvent or purification process, by distilling and condensing, by solvent volatilize and condense reach dissolved in solvent it is molten Matter, solid impurity etc. are separated, to achieve the purpose that recycling or purification.Especially in laboratory science experimentation, Solvent recovery unit is mainly made of round-bottomed flask, still head, thermometer, condenser pipe, reception pipe and receiving bottle, in order to reach Preferable condensation effect, condenser pipe are usually elongated condensation pipe, are condensed using recirculated water, tap water as condensate liquid, because This, the recyclable device occupied space of solvent is big, and it is not very convenient to build recyclable device.

The utility model is in view of the above-mentioned problems, propose a kind of condensable still head, it is therefore intended that solves common steaming It evaporates head and does not have condensation effect, the problem that condenser pipe pipe is too long, it is hard to build recyclable device, recyclable device occupied space is big.

Summary of the invention

To solve the above-mentioned problems, the utility model provides a kind of condensable still head, including upper cover and cylindric Still head ontology, still head body interior hollow parts are the condensation chamber of still head, and the top of still head ontology has upper cover Connection, it is characterised in that: one layer of annular cooling chamber for being surrounded on condensation chamber is arranged in the condensation chamber, and centre has the cone of protrusion Shaped bases, condensation chamber import protrude from condensation chamber conical top, the condensation chamber, and setting is cold at the platform of conical lower portion Condensate outlet facilitates condensate liquid to flow out, and condensation chamber entrance is also equipped with inner sleeve, the inner sleeve, and top closure is interior There is a pair of of leak hole beside casing top, the gas for generation of volatilizing after solvent heating enters condensation chamber from the leak hole of inner sleeve, And it is condensed by condensation chamber, the condensate liquid generated after condensation is flowed out by condensate outlet.

Further, the cooling chamber, cooling liquid inlet are located at below cooling chamber, and cooling liquid outlet is located at cooling Above room.Coolant liquid (mainly tap water) enters cooling chamber by the cooling liquid inlet of lower section, and above cooling chamber Outflow.

Further, gained still head ontology, upper part have the still head external screw thread for connecting with upper cover.

Further, the upper cover, upper part have outlet, and have upper cover internal screw thread, upper cover and steaming on upper lid An ontology is evaporated to be threaded by upper cover internal screw thread and still head external screw thread.

Further, the upper cover, inside the outlet pipe also are provided with screw thread.

Further, there is a screw thread at the condensation chamber import, both ends, and it is deep into condensation chamber one end and is and inner sleeve Pipe screw thread connection.

Further, the condensation chamber import stays in the screw thread of the external one end of still head sheet and the outlet of upper cover Screw thread inside pipe matches.

The utility model can be threadedly coupled, ground connector in condensation chamber import in outside with ground connector, Outside is ground, can be closed with the ground phase of round-bottomed flask, thus, facilitate and still head is connected on round-bottomed flask, receives The condensation of the steam of solvent on round-bottomed flask.

Further, for preferably condensation effect, still head ontology, upper cover, inner sleeve, ground connector, material For metal.

The utility model, still head can be connected directly between on round-bottomed flask, and the cooling liquid inlet on still head is passed through Tap water is entered in inner sleeve as coolant, the steam of solvent by condensation chamber import, and from the leak hole side of inner sleeve While entering condensation chamber condensation, condenses indoor steam and condensed out by cooling indoor coolant liquid, at the top of inner sleeve Sealing can prevent the solvent of condensate drop in condensation chamber from flowing back into round-bottomed flask from drippage on inner sleeve.

The utility model, a kind of condensable still head, multiple still heads can be together in series, the condensation chamber of still head into The outlet of the upper cover of mouth and concatenated still head is threaded, so that concatenated condensable still head can increase condensation Effect, therefore, the utility model can reach satisfied effect according to actual use situation, multiple still heads of easily connecting Fruit.

The utility model, a kind of condensable still head, experimentation are built conveniently, occupy little space, and convenient more A still head is together in series.
