Abstract
The utility model provides a kind of for condensing reflux and the experimental provision distilling separatory continued operation, it comprises selects isocon, return duct, separating tube, shunting piston, hollow straight pipe, water condensing tube, water inlet, discharge outlet, the utility model can be used for the condensing reflux in experiment of synthetic chemistry and distills the continued operation of separatory two experimental procedures, in experimental implementation process, do not need to reinstall laboratory apparatus, easy to use, simple to operate, there is desirable condensing reflux and distillation separatory experiment effect.
Description
Technical field
The utility model relates to a kind of experimental provision used in laboratories, field such as chemical industry, medicine, biologies.Particularly relate to a kind of Novel experiment device that can carry out continued operation use in chemical synthesis preparation experiment process to condensing reflux and distillation separatory two experimental procedures.
Background technology
In chemical synthesis preparation experiment, experimenter often needs the continued operation carrying out condensing reflux and distillation separatory two experimental procedures.When synthetic reaction is carried out in the heating of liquid towards mixture, need to take condensing reflux to operate, make the mixture steam condensing liquefaction produced in heating process, be back in reaction unit and continue synthetic reaction.After synthetic reaction terminates, then by the operation of distillation separatory, different boiling component in liquefied mixture to be made to realize being separated through gasification, condensation liquefaction effect, obtains corresponding component.Normal conditions, in these two continuous laboratory operating procedures, all relate to the installation of condenser pipe.When carrying out condensing reflux experimental implementation, need vertically condenser pipe to be installed above reaction unit, and when carrying out distillation separatory experimental implementation, then need to use still head coupled reaction device and condenser pipe, and require that condenser pipe is tilted to down in the horizontal direction and be connected with liquid collector.Therefore experimenter needs after condensing reflux experimental implementation terminates, re-assembly adjustment related experiment instrument, distillation separatory experimental implementation could be continued, add complexity and the workload of experimental implementation, be unfavorable for condensing reflux and distill carrying out continuously of separatory two laboratory operating procedures.
Summary of the invention
The purpose of this utility model is to provide one not to be needed to re-assembly laboratory apparatus, just can carry out the Novel experiment device of condensing reflux and distillation separatory experimental implementation continuously.
The technical scheme that the utility model is adopted for achieving the above object is: a kind of for condensing reflux and the experimental provision distilling separatory continued operation.It comprises selects isocon, return duct, separating tube, shunting piston, hollow straight pipe, water condensing tube, water inlet, discharge outlet.Described selection isocon upper port is connected with hollow straight pipe lower port, and bottom is inserted with shunting piston, and described selection isocon pipe shaft one middle side part upper position is connected with return duct, and in the middle part of opposite side, upper position is connected with separating tube.Described return duct tilts upward and is connected with selecting isocon, and bottom port is connected with reaction unit.Described separating tube tilts upward and is connected with selecting isocon, and bottom port is connected with liquid collector.Described shunting piston is inserted in be selected bottom isocon, can rotate in selection isocon, and can move up and down along selection isocon pipe shaft.Described shunting piston upper surface is a clinoplain.Described hollow straight pipe outer cover has the water condensing tube of equal length, and lower port is connected with selection isocon.Described water condensing tube is connected to water inlet near pipe shaft bottom position, is connected to discharge outlet near pipe shaft tip position.Of the present utility modelly to be characterised in that: terminate with condensing reflux experimental implementation in existing experimental implementation, need to reinstall regulation experiment instrument just can proceed distillation separatory experimental implementation and compare, the utility model can realize the continued operation of condensing reflux and distillation separatory two experimental procedures, and does not need to re-assembly laboratory apparatus.The utility model by shunting piston selecting moving up and down and rotating in isocon, can adjust shunting piston upper inclined surface and selecting the position in isocon.When shunting piston upper inclined surface lower limb and contacting with return duct lower limb, the steam condensing liquid produced in experimentation is back in reaction unit by return duct, realizes condensing reflux experimental implementation object.When shunting piston upper inclined surface lower limb and contacting with separating tube lower limb, the steam condensing liquid produced in experimentation enters gas collecting apparatus by separating tube, reaches distillation separatory experimental implementation object.Overcome in usual organic synthetic experiment, to carry out the shortcoming that condensing reflux and the continuous experimental implementation of distillation separatory need reinstall regulation experiment instrument.
Accompanying drawing explanation
Fig. 1 is a kind of for the structural representation of condensing reflux with the experimental provision of distillation separatory continued operation.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail, as shown in Figure 1: 1 selects isocon, 2 return ducts, 3 separating tubes, 4 shunting piston, 5 hollow straight pipe, 6 water condensing tubes, 7 water inlets, 8 discharge outlet.
Embodiment
Condensing reflux and the continuous experimental implementation of distillation separatory are carried out to liquid reaction mixture: running water enters water condensing tube 6 by water inlet 7, discharges through discharge outlet 8, forms water condensation environment.Adjustment shunting piston 4, selecting the position in isocon 1, makes shunting piston 4 upper inclined surface lower limb contact with return duct 2 lower limb.Reactant liquor adds thermogenetic mixture steam and enters selection isocon 1 by return duct 2, then rising enters hollow straight pipe 5, and mixture steam by the heat exchange action of water condensing tube 6, is condensed into liquid state by gaseous state in hollow straight pipe 5.Condensation mixed liquor is back to by hollow straight pipe 5 and selects isocon 1 afterwards, guiding, being back to reaction unit, the condensing reflux experiment purpose of realization response liquid by return duct 2 through selecting to shunt piston 4 upper inclined surface in isocon 1.After condensing reflux operation terminates, continue the operation of distillation separatory.Adjustment shunting piston 4, shunting piston 4 upper inclined surface lower limb is contacted with separating tube 3 lower limb, heating reaction mixture is to required component gasification, the steam that liquid composition produces is entered by return duct 2 and selects separating tube 1, rise again and enter hollow straight pipe 5, required Component vapor realizes heat exchange by water condensing tube 6 in hollow straight pipe 5, liquid state is converted into by gaseous state, the condensate liquid of required component is entered by hollow straight pipe 5 and selects in isocon 1 afterwards, guide through shunting piston 4 upper inclined surface, external liquid collector is flowed into by separating tube 3, the distillation separatory experiment purpose of required component in realization response liquid.
Above embodiment is only the preferred version of this utility model, when not departing from the utility model principle, also can make other transformation and distortion to this device, being all considered as belonging to protection domain of the present utility model.
