Description
Technical field:
This utility model relates to equilibrium still, particularly a kind of novel liquid-liquid equilibrium still.
Background technology:
Liquid-liquid equilibrium device used in experiment at present, all there are some problems: the kettle inner chamber of the equilibrium still that (1) is present is typically all cylinder, thus need to use larger amount of feed liquid, add use cost, dead band is there is in cylinder or cube still type equilibrium still in equilibrium process, cause equilibration time long, or data are inaccurate；(2) various cylinders or cube still shape designed in (including that concave side walls designs), all there is dead band；Although in some liquid-liquid equilibrium stills, having the structure added with baffle plate in design, but also there is dead band in baffle plate side, and near dead band, liquid flowing is not smooth, and mass-and heat-transfer is insufficient, extends the time arriving balance, even results in the equilibrium criterion recorded unreliable；(3) during the liquid-liquid equilibrium still at glass material designs, kettle having phase sample tap or thermometer temperature-measuring port up and down, the existence of this sample tap or temperature temperature-measuring port causes glass equipment intensity low, thus reduces its service life.
Summary of the invention:
The purpose of this utility model is a kind of rational in infrastructure, novel liquid-liquid equilibrium still that using effect is good of design.
The technical solution of the utility model is, a kind of novel liquid-liquid equilibrium still, it includes kettle, kettle cover, it is characterized in that: be provided with heating agent outlet on kettle top, it is provided with heating agent entrance in kettle bottom, it is equipped with kettle cover at kettle top, kettle cover has thermometer hole, thermometer boss it is equipped with in thermometer hole, kettle cover is equipped with speed governing hole, speed governing rod it is equipped with in speed governing hole, the bottom of speed governing rod is provided with blade, it is provided with speed regulator at the top of speed governing rod, kettle cover assembles condensate port, condensate port is equipped with condenser, it is provided with exsiccator at the top of condenser；The corner of the vertical section of kettle is the excessive lead angle of circular arc.Described speed governing rod is metal material.The horizontal section of described kettle is the arc groove that four grades are big, and each arc groove has identical major radius and short radius, and the major radius of adjacent arc groove is connected with short radius.Difference between described major radius and short radius is 1/10th of the major radius value of twice.
This utility model is rational in infrastructure, and using effect is good, can effectively extend the service life of equilibrium still, can preferably record again equilibrium criterion.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model,
Fig. 2 be the horizontal section of kettle of the present utility model be structural representation.
Detailed description of the invention:
Embodiment is described in detail in conjunction with accompanying drawing
Embodiment 1,
A kind of novel liquid-liquid equilibrium still, it includes kettle 10, kettle cover 2, heating agent outlet 9 it is provided with on kettle top, it is provided with heating agent entrance 6 in kettle bottom, it is equipped with kettle cover at kettle top, kettle cover has thermometer hole, in thermometer hole, is equipped with thermometer boss 3, kettle cover is equipped with speed governing hole, speed governing rod 11 it is equipped with in speed governing hole, the bottom of speed governing rod is provided with blade 5, is provided with speed regulator 1 at the top of speed governing rod, assembles condensate port on kettle cover, condensate port is equipped with condenser 8, is provided with exsiccator 7 at the top of condenser；The corner of the vertical section of kettle is the excessive lead angle of circular arc 4；Described speed governing rod is metal material.
In equilibrium still operating process, at the end of stirring, need sample analysis；Because liquid-liquid equilibrium still has upper and lower two liquid phases, it is both needed to sampling, to this end, existing equilibrium still is provided with upper and lower two sample taps；But the equilibrium still to glass material, the existence of this sample tap, greatly reduce the intensity of equipment, in turn result in equipment frangible, the problems such as equipment life is short.To this end, structure of the present utility model is: thermometer boss, during stirring, this mouth is used for thermometric, after stirring terminates, takes out sleeve pipe in order to take upper phase sample；Stirring rod is stainless steel, is connected with screw thread between its with speed regulator, when taking off phase sample, turns on screw thread dip sampler and carries out taking and take off phase sample；Seam between all glass materials of the present embodiment all uses ground to design.
Embodiment 2,
On the basis of embodiment 1, the present embodiment further defines the structure of kettle, the horizontal section of the kettle described in the present embodiment is the arc groove 15 that four grades are big, and each arc groove has identical major radius 12 and short radius 13, and the major radius of adjacent arc groove is connected with short radius；/ 10th of the major radius value that difference 14 is twice between major radius and short radius described in Ben.Liquid rotates in equilibrium still counterclockwise, and the cavity of equilibrium still is impacted and all born by circular arc wall by such liquid, and stress is highly uniform, essentially eliminates dead band, samples the most accurate.
Above-described embodiment is only for clearly demonstrating example, and not restriction to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here without also cannot all of embodiment be given exhaustive, and within the protection domain that the obvious change thus extended out or variation are created still in this utility model.
