Abstract
The invention discloses a waste liquid continuous collection device of a vacuum rotary evaporator. A condenser master three-way valve is added below a condenser of a traditional vacuum rotary evaporator so as to control condensate to flow into a waste liquid bottle at the left or right side. The two waste liquid bottles at the left side and the right side are used for alternatively collecting the condensate. When one bottle is full and the other bottle is alternated for collection, the concentration process is not stopped. Therefore, when a large quantity of solution is concentrated continuously, the concentration efficiency is improved and the consumption of electricity and cooling water is lowered. The lower part of each waste liquid bottle which is full of condensate is provided with a liquid discharging valve, and an upper connecting pipe is provided with a three-way valve and an air inlet, so that the pressure inside the bottle is balanced and the discharge of the condensate is facilitated. After the liquid discharging valves and the air inlets are closed, the waste liquid bottles can be alternated for collecting condensate next time, so that the waste liquid is collected continuously. The waste liquid continuous collection device has significance for improving the concentration efficiency of chemical liquids in laboratories as well as lowering the waste of water and electricity.
Description
Technical field
The present invention relates to a kind of vacuum rotary evaporator waste liquid continuously trapping system, the waste liquid device for continuously recycling of the medium and small vacuum rotary evaporator of espespecially a kind of use for laboratory.
Background technology
Vacuum rotary evaporator is chemistry, the indispensable conventional equipment in pharmaceutical test chamber, is widely using aspect the concentrated and chemical synthesis of liquid.Generally formed by several parts such as water bath heating device, round-bottomed flask, condensing unit, vacuum plant, waste collecting device and control device.Owing to being carry out liquid under negative pressure state concentrated, therefore, solvent can seethe with excitement in lower temperature, when improving thickening efficiency, also greatly reduces the destruction of the solute that causes because of high temperature and long-time concentrating.
The problem that the common vacuum rotary evaporator in present laboratory exists is: the waste collection bottle only has one, small volume, and when the solution of concentrated larger volume, the concentration process of having to repeatedly interrupt is in order to pour out the liquid in the waste collection bottle.Vacuum level before returning to, the pumpdown time that needs to grow can.Like this, both waste the time, also wasted electricity and cooling water.In view of this, it is supporting with it that vacuum rotary evaporator is badly in need of developing a kind of device that can collect continuously waste liquid.
Summary of the invention
The present invention is a kind of waste liquid device for continuously recycling of vacuum rotary evaporator.Solution in the rotation round-bottomed flask evaporates under negative pressure and heating condition, and solvent vapo(u)r is pumped to condensation in the condenser, drops onto condenser.By the total triple valve of condenser, control condensate stream to the left side or the receiving flask on the right.About the in turn control by the total triple valve of condenser of two waste liquid bottles, the interleaved collection condensate liquid.Wherein one bottle collect full after, when changing another bottle into and collect, need not to stop concentration process.Thereby when the relatively large solution of continuous concentration, improved thickening efficiency, reduced the consumption of electricity and cooling water.Bleeder valve is arranged at the waste liquid bottle bottom of collecting full condensate liquid, and triple valve and air inlet are arranged on the tube connector of top, with the equilibration flask internal pressure, is convenient to emitting of condensate liquid.Close waste liquid bottle bleeder valve and air inlet, just can rotate and carry out collecting condensate liquid next time, thereby realize the continuous collection of waste liquid.
The present invention wastes significant to raising laboratory liquid thickening efficiency, reduction water, electricity.

The specific embodiment
With the present invention's " a kind of vacuum rotary evaporator waste liquid continuously trapping system " when carrying out Vacuum Concentration, solvent vapo(u)r is drawn in the condenser (1) and is condensed pipe (4) cooling, drop is flowed into the waste liquid bottle (12) on the left side by the total triple valve of condenser (8) control, this moment, the tube connector triple valve on waste liquid bottle top, the left side was opened it, the bleeder valve of bottom is closed, air wherein is pumped, and cooling fluid flows in the bottle through the total triple valve of condenser (8), tube connector (9) and tube connector triple valve (10).When the condensate liquid of collecting in the bottle will be expired, total triple valve (8) is led to the waste liquid bottle (12) on the right, as mentioned above, condensate liquid flows in the bottle.At this moment, tube connector triple valve (10) ventilation on left side waste liquid bottle (12) top can be opened the bleeder valve (13) of bottom after the balance, emit the condensate liquid in the bottle.After emptying, close bleeder valve (13) and tube connector triple valve (10), can enter next circulation, and so forth, realize the continuous waste collection of large volume concentrate.
