Description
Technical field
The utility model relates to experimental provision, especially relates to a kind of normal pressure liquid-liquid equilibrium still.
Background technology
Liquid liquid equilibrium data are main foundations of extraction tower design and production operation, and the acquisition of equilibrium criterion mainly depends on measuring at present, and equilibrium still is an important experimental facilities of measuring equilibrium criterion.
At present, there are shortcomings such as structure imperfection, narrow application range in employed various liquid-liquid equilibrium still.The for example disclosed multifunction clips shell type of CN2626572 utility model liquid-liquid equilibrium still and the disclosed modified multifunction clips of CN201026404 utility model shell type liquid-liquid equilibrium still, there is following problem: 1. because there is the liquid dead angle in the sample tap up and down of its design for level design, liquid can not fully mix, and can cause liquid to be bonded at and stop up capillary on the capillary tube inner wall easily, and cleaning is inconvenient to influence next experimental result; The sample tap fixed constraints solution ratio that uses of extraction, experimental implementation is dumb; 3. the arm stirrer of its design is not ideal for the high-viscosity material mixing effect, and pollutes experimental liquid easily.Owing to reason on project organization, cause equilibrium still can not solve the problem at sample tap liquid dead angle, and can not measure liquid-liquid equilibrium data under the condition of different temperatures.
Summary of the invention
The purpose of this utility model is exactly to provide a kind of simple in structure, easy to operate, measurement result normal pressure liquid-liquid equilibrium accurately still for the defective that overcomes above-mentioned prior art existence.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of normal pressure liquid-liquid equilibrium still, comprise kettle, insulation jacket, condenser pipe, drier, phase sample tap up and down, agitating device, the top of described kettle is the still mouth, this still mouth is plugged with rubber stopper, described insulation jacket is located at outside the kettle, the bottom of this insulation jacket is provided with water inlet, top is provided with delivery port, described condenser pipe is located at the top of kettle, described drier is located at the top of condenser pipe, in this drier drier is housed, it is characterized in that the described sample tap of phase up and down comprises the sampling syringe needle, the sampling probe nook closing member, described sampling syringe needle passes rubber stopper, described sampling probe nook closing member is inserted in the sampling syringe needle, described agitating device comprises magnetic stir bar, magnetic stirring apparatus, described magnetic stir bar are placed on the bottom in the kettle, and described magnetic stirring apparatus is located at the bottom of insulation jacket.
Also be provided with the thermometer slot on the described insulation jacket, in this slot microthermometer be housed.
The interface of described condenser pipe, drier is a ground.
Described water inlet, delivery port are connected with the thermostatic water-circulator bath groove.
Described sampling probe nook closing member is inserted in the sampling syringe needle and seals with the vacuum sealing.
Compared with prior art, the utlity model has simple in structure, easy to operate and advantage such as measurement result is accurate, be embodied in: 1. adopt the not magnetic agitation of foul solution, adjustable-speed, can measure the liquid-liquid equilibrium data of high and low viscosity; 2. adopting temperature-controlled precision is the water bath with thermostatic control heating of 0.05 ℃ in soil, can measure liquid-liquid equilibrium data under the condition of different temperatures; 3. equilibrium still top connects condenser pipe, and evaporating in the time of can preventing the temperature rising influences the liquid-liquid equilibrium result; 4. the condenser pipe top connects drier, can avoid the water in air branch to enter system; The syringe needle interpolation of taking a sample when 5. testing is gone into the sampling probe nook closing member and is sealed with the vacuum sealing, avoids the liquid dead angle to exist; Slowly extract the sampling probe nook closing member when 6. taking a sample out, levels liquid is filled the sampling probe caliber respectively, avoids the stable of system wobble effects equilibrium system.
