Description
Technical field
The utility model is related to experiment equipment technical field, and molecular weight experiment is surveyed more particularly, to a kind of cryoscopic method
Attemperator.
Background technology
It is the classical project in Physical Chemistry Experimental Teaching, experimental basis hardly possible volatilization that cryoscopic method, which determines molecular weight,
The colligative properties of weak solution --- freezing point reduces to realize.It is molten by determining under conditions of known solvent and Solute mass
Liquid freezing point can calculate the molecular weight of solute with respect to the decreasing value of neat solvent freezing point, in field research, generally use water
It is used as solvent.The freezing point of water is 0 DEG C under normal pressure, in order that pure water and solution to be measured cooling freeze, it is necessary to provide temperature
Lower ice bath environment, it is exactly conventional ice bath to add sodium chloride in mixture of ice and water.
Currently, cryoscopic method surveys device of the molecular weight experiment instrument used for electromagnetic agitation and muff one,
Tool housing is made of iron sheet, coating paint is used as protection.When testing freezing point, with Inner splendid attire mixture of ice and water conducts of stainless steel
Ice bath is positioned in muff, then will be equipped with pure water to be measured or the freezing point pipe of solution is placed in inner cylinder.One of shortcoming of this device
Be mixture of ice and water amount it is larger, electromagnetic agitation can not effectively stir ice bath, and electromagnetic agitation is often used without in practical operation,
But be manually stirred.Therefore, electromagnetic mixing apparatus turns into the redundancy feature of the equipment.Further, since ice bath
In contain a large amount of sodium chloride, chlorion therein is severe corrosive ion, during experimental implementation, and ice bath solution is inevitable
Inner cylinder is carried over, is splashed and is spread on apparatus surface and device is caused the burn into shortening device life-span.
Utility model content
In order to overcome above-mentioned existing technological deficiency, the purpose of this utility model is to provide a kind of anti-sliding stop, will
Muff and ice bath inner cylinder unite two into one, while preventing ice bath solution is jumped from splashing, effectively prevent the cryoscopic method of corrosion from surveying to divide
Son amount experiment attemperator.
In order to achieve the above object, the utility model is achieved through the following technical solutions：
The technical program be a kind of cryoscopic method survey molecular weight experiment attemperator, including housing, inner cylinder, upper lid and
Anti-skid base；The housing is hollow structure, and housing bottom threaded connection is provided with anti-skid base, and anti-skid base is to the hollow knot of housing
Structure is closed；Inner cylinder top in the housing is provided with square step；The cover rim matches with square step；Upper lid
Provided with the perforate for facilitating instrument to insert；The housing and upper lid are made of anticorrosion material.
Compared with prior art, the beneficial effects of the utility model are：The present apparatus is simple in construction, easy to use, effectively anti-
Locking apparatus is slided, and muff and ice bath inner cylinder are united two into one, and prevents ice bath solution is jumped from splashing；Housing and upper lid use anticorrosion material
Material is made, the corrosion that effective means is produced, the use time of extension fixture.Remove electromagnetic agitation function during using the present apparatus, from
And reach convenient and practical, cost-effective, environmental protection purpose.
Brief description of the drawings
The utility model will illustrate by example and with reference to the appended drawing, wherein：
Fig. 1 is main structure schematic diagram of the present utility model.
Fig. 2 is overlooking the structure diagram of the present utility model.
Marked in figure：Housing 1, inner cylinder 2, upper lid 3 and anti-skid base 4.
Embodiment
Below in conjunction with the accompanying drawings, the utility model is described in detail.
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only to explain
The utility model, is not used to limit the utility model.
Embodiment 1, as shown in Figures 1 and 2, the utility model are that a kind of cryoscopic method surveys molecular weight experiment insulation
Device, including housing 1, inner cylinder 2, upper lid 3 and anti-skid base 4；The housing 1 is hollow structure, and the connection of the bottom thread of housing 1 is set
There is anti-skid base 4, anti-skid base 4 is closed to the hollow structure of housing 1；The top of inner cylinder 2 in the housing 1 is provided with square platform
Rank；The edge of upper lid 3 matches with square step；Upper lid 3 is provided with the perforate for facilitating instrument to insert；The housing 1 and upper
Lid 3 is made of anticorrosion material.
The upper edge of lid 3 matches with square step, prevents that lid 3 is slided at random in experimentation, while square step
The ice bath solution spilt in experiment can be made to pass back into inner cylinder 2, it is to avoid polluted to experimental situation.The housing 1 of attemperator
For hollow structure, to improve heat insulation effect, insulation material is filled to the hollow structure of housing 1 according to different use environments, simultaneously
Hollow structure is closed installed in the bottom of housing 1 by the threaded connection of anti-skid base 4.Insulation dress with anti-skid base 4
Put while effectively prevent slip, it is ensured that the security of experiment.Two small sircle holes are opened up on upper lid 3, one is used to insert temperature
Degree meter, one is used to insert hand mixer.A big hole is opened up on upper lid 3 simultaneously, for inserting freezing point pipe.In experiment
During, to prevent that freezing point pipe shakes during experimental implementation, one and freezing point pipe equivalent diameter are connected on big hole
Cylinder, prevent freezing point pipe from significantly swinging.
The present apparatus unites two into one muff and ice bath inner cylinder, prevents ice bath solution is jumped from splashing；Housing 1 and upper lid 3 can be used
The anticorrosive property material such as plastics is made, the corrosion effectively prevented, the use time of extension fixture.Remove during using the present apparatus
Electromagnetic agitation function, so as to reach convenient and practical, cost-effective, environmental protection purpose.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Any modifications, equivalent substitutions and improvements made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
