The rotary evaporator is characterized by comprising a distillation flask (1), a constant-temperature water bath heater (2), a rotary device (3), a material storage constant-pressure funnel (4), a condenser (5) and a collection flask (6), wherein the distillation flask (1) is connected with the rotary device (3); the rotary device (3) drives the distillation flask (1) to rotate; a glass sleeve (7) is communicated with the distillation flask (1); a liquid leading glass guide pipe (8) is sleeved in the glass sleeve (7); one end of the liquid leading glass guide pipe (8) is connected with a three-way connector (9A) and the other end of the liquid leading glass guide pipe (8) is connected into the distillation flask; the three-way connector (9A) is further connected with the material storage constant-pressure funnel (4); a connector (9B) is connected with the condenser (5); the condenser (5) is provided with an air pipe (11) to be connected with a vacuum pump (12). According to the rotary evaporator disclosed by the utility model, the problem of a common rotary evaporator that feeding and rotary evaporation cannot be carried out at the same time is mainly solved.
Description
Technical field
The utility model relates to natural product extraction, concentrates, in the separation, purification field, be specifically related to a kind of improvement of Rotary Evaporators.Be particularly useful for evaporating easy splash, the material that is difficult to evaporate and middle trial production.
Background technology
Rotary Evaporators generally is used for concentrating of medicine, food, biological industry, mainly is to drive distilling flask in continuous rotation by circulator, forms rotating thin film and increases disengagement area, the quickening evaporation rate.Simultaneously negative pressure has reduced the boiling point of solvent, has reduced heating-up temperature, and the heat-sensitive ingredients of concentrate is had good protective effect.But present Rotary Evaporators all needs to take off frequently evaporimeter and adds materials, and increases a lot of manpower work.Some reduces the number of times that adds materials by the capacity that increases evaporimeter, increased the cost cost of instrument like this and brought inconvenience to installation, and the material effect of commute splash is not satisfactory.
Summary of the invention
Evaporation and charging can not be carried out simultaneously when the purpose of this utility model was to overcome rotary evaporation, and a kind of Rotary Evaporators of controllable continuous charging is provided.
The purpose of this utility model is achieved through the following technical solutions:
A kind of Rotary Evaporators of controllable continuous charging, comprise that distilling flask (1), constent temperature heater (2), whirligig (3), storing constant pressure funnel (4), condenser (5), collection flask (6) is characterized in that: distilling flask (1) is connected with glass bushing (7) by interface (9D), and whirligig (3) and rotating control assembly (10) are by the rotation of control glass bushing (7) rotation drive distilling flask (1).Drawing liquid grass tube (8) is enclosed within the glass bushing (7), drawing liquid grass tube (8) one ends is connected with three-way interface (9A), the other end feeds in the distilling flask, three-way interface (9A) is connected with liquid storage constant pressure funnel (4) simultaneously, and two other three-way interface (9B), (9C) are connected with glass bushing (7) with condenser (5) respectively.Condenser is provided with tracheae (11) and links to each other with vavuum pump (12).
The Rotary Evaporators of described a kind of controllable continuous charging, its storing constant pressure funnel are provided with controlled charging valve (13) and ground glass stopper (14).
The Rotary Evaporators of described controllable continuous charging is characterized in that total interface is the ground interface.
The Rotary Evaporators of described controllable continuous charging is characterized in that condenser is serpentine condenser, and tracheae (11) links to each other with vavuum pump (12).
The utility model has following advantage compared with prior art:
By liquid storage constant pressure funnel and grass tube, reach evaporation and carry out reinforced the time, the valve by the control constant pressure funnel makes evaporation and charging reach balance, and machine can be worked automatically for a long time and need not manually be guarded, and can significantly reduce the manpower work.Avoided frequent dismounting distilling flask simultaneously, prolonged the service life of machine and strengthened the machine sealing.
For the material of some easy splashes and foaming, by the continuous feed system, can control the amount of distilling flask material, the splash of better controlled material and foaming.Perhaps by the continuous interpolation defoamer (as n-butanol) of constant pressure funnel reaching the purpose of froth breaking, and don't can be because disposable adding defoamer causes defoamer because of problems such as the amount of evaporation consumption are excessive.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
By reference to the accompanying drawings, specific embodiment of the utility model is described.
Embodiment one: the Rotary Evaporators of described controllable continuous charging comprises distilling flask (1), water bath with thermostatic control heater (2), whirligig (3), storing constant pressure funnel (4), condenser (5), collects flask (6) as shown in Figure 1.At first will concentrate material and all pour in the storing constant pressure funnel (4) stopper beyond the Great Wall into, by control charging valve (13) the part feed liquid is put into distilling flask, valve-off, open vavuum pump and begin rotary evaporation, when treating that condenser begins condensation, charging valve (13) is controlled the speed of evaporation and the speed of charging reaches balance by controlling, and makes the inventory control of distilling flask at certain level, has well prevented the splash of material.Can allow Rotary Evaporators work for a long time like this, in the lump concentrate be taken out after the end to be concentrated.
Embodiment two: the Rotary Evaporators of described controllable continuous charging comprises distilling flask (1), water bath with thermostatic control heater (2), whirligig (3), storing constant pressure funnel (4), condenser (5), collects flask (6) as shown in Figure 1.Need add defoamer when concentrated for the material of easy foaming, defoamer (be example with the n-butanol) can be added in the storing constant pressure funnel (4) stopper beyond the Great Wall, then material is added in the distilling flask (1), along with the n-butanol meeting of carrying out of evaporation is constantly lost, constantly add n-butanol by control charging valve (13) and come froth breaking.Last concentrate separates by separatory funnel and a spot of n-butanol, has namely obtained concentrate.
Not only the controllable continuous charging can be realized in the manner described above, the concentrating of material of easy foaming and splash can also be solved.
Claims (4)
