Description
Technical field
The utility model relates to evaporation equipment, is specifically related to a kind of vacuum evaporation instrument.
Background technology
Vacuum rotary evaporator mainly is the solvent for a large amount of effumabilities of continuous still under reduced pressure, and the distillation of the receiving liquid during especially to the concentrated and chromatographic isolation of extract can separate and the purification reaction product.Its basic principle is exactly vacuum distillation, and namely under vacuum condition, when solvent distilled, distilling flask was in continuous rotation.
Yet, in still-process, because the liquid that is distilled contains the class materials such as saponin(e, cause foam occurring in the process of rotary distillation, when foam produces in a large number, if untimely processing, splash can appear, cause the failure of the distillation of concentrated or receiving liquid, not only lose time, and can cause because of the rotary distillation overlong time loss of active principle.Therefore inventing a kind of anti-foamng Rotary Evaporators is highly profitable.
Simultaneously, the foam of generation is all influential to quality and the efficient of distillation, and distillation also has the inwall that a large amount of foams adheres to distilling flask after finishing, and needs distilling flask is repeatedly cleaned, and not only wastes time and energy, and has also caused simultaneously the waste of product.
Summary of the invention
For solving the problems of the technologies described above, the utility model proposes a kind of anti-foamng vacuum rotary evaporator, to reach residue on raising distillation quality and efficient, the minimizing distilling flask inwall, convenient purpose of cleaning.
For achieving the above object, the technical solution of the utility model is as follows: a kind of anti-foamng vacuum rotary evaporator, comprise trestle table, condenser pipe, reception flask, concentrated bottle, heating water tank, concentrated bottle is arranged on the trestle table, the outlet of concentrated bottle is connected with condenser pipe by tube connector, the below of condenser pipe is connected with the reception flask, it is characterized in that: described concentrated bottle is provided with agitating device, the bottleneck of described concentrated bottle is provided with photoelectric sensor, establish control relay on the described heating water tank, described photoelectric sensor links to each other with described control relay.
Further, described agitating device comprises micro machine, shaft, blade, and described micro machine links to each other with shaft, and a plurality of blades are housed on the shaft.
Further, described blade is sandwich construction, and the edge shape of blade adapts with the inner wall shape of concentrated bottle.
The utlity model has following technique effect: (1) is because concentrated bottle of the present utility model is provided with agitating device, when distillation and concentration, agitating device begins to stir, solution in the concentrated bottle is uniformly mixed, the heat of heating water tank also can evenly be delivered to solution, and owing to stirring action, the foam of generation is also stirred brokenly in a large number simultaneously, thereby reduced in a large number foam, thereby improved quality and the efficient of distillation and concentration.
(2) on the shaft of the present utility model a plurality of blades are housed, described blade is sandwich construction, the edge shape of blade adapts with the inner wall shape of concentrated bottle, and blade rotates under the drive of shaft, and concentrated bottle inwall is swiped, the foam that adheres on the inwall is come off, offseting foam-expelling has better effect, can reduce the rear wash number to concentrated bottle of distillation simultaneously, time saving and energy saving, also avoid simultaneously the waste of product, saved resource.
(3) bottleneck of concentrated bottle of the present utility model is provided with photoelectric sensor, and photoelectric sensor links to each other with the control relay of heating water tank, suppose to produce when more when foam, photoelectric sensor can be responded to reception, control relay cuts out, make the heating water tank stopped heating, prevent the foam splash, guarantee handling safety.
