The utility model has the advantages of prior art's drawback, the reasonable novelty of structural design can be overcome to it.
Description
Technical field
This utility model is related to a kind of flask of homogeneous heating, belongs to teaching equipment field.
Background technology
Flask is that have neck glass drying oven used in laboratory, for holding liquid material.Because can with resistance to certain heat quilt
It is referred to as flask.Flask generally have flat and round bottom point.Flat be called boiling flask, round bottom be round-bottomed flask.Flask leads to
Often there is the outward appearance of the thin neck of round tripe, significantly different from beaker.Its slot is used to prevent solution from spilling or reduces solution
Evaporation, and the use of rubber closure can be coordinated, to connect other glass equipment.In teaching test, the heating of flask is general
It is to adopt alcohol burner, the heating of alcohol burner is single-point heating, and heating position concentrates on drag center.Such mode of heating
Make the heated liquid in flask uneven, need to be stirred, using inconvenience in heating process.
Utility model content
In view of the shortcomings of the prior art, technical problem to be solved in the utility model is to provide a kind of heating all
Even flask, homogeneous heating, convenient use.
For solving above-mentioned technical problem, this utility model adopts the technical scheme that, a kind of flask of homogeneous heating, including
Flask body, flask body is hemispherical, and the bottom of flask body is provided with horizontal ends, and horizontal ends are round sheet；Institute
The sidepiece stating flask body is provided with a fractionating column, and fractionating column is a tubular pipe, the axis of the tubular pipe of fractionating column
Line and horizontal ends place plane are in 47 degree of angles；One hemispheric groove, the radius of groove are provided with described horizontal ends
For the 1/8 of horizontal ends radius, the centre of sphere of groove and the horizontal ends upper surface center of circle are same point；If being provided with described horizontal ends
The hemispheric groove of dry uniformly arrangement, all of groove is ringwise arranged with the centre of sphere of groove for the center of circle；Described groove
Radius be 1.75 times of radius of groove；The centre of sphere of described groove is horizontal ends radius to the distance of the centre of sphere of groove
1/2.37；Heating pole is provided with described groove, heating pole is perpendicular to horizontal ends.
Optimize, the flask of above-mentioned homogeneous heating, the thickness of described horizontal ends is 2.45 times of flask sidewall thickness.
The utility model has the advantage of the drawbacks of it can overcome prior art, reasonable in design novelty.The application's
Design arranges some grooves by increasing a groove at the middle part of horizontal ends and outside groove.The setting of groove is just
Flame to alcohol burner, in heating process, increased the contact area of the liquid in the middle part of flask bottom and thermal source, improves and add
Thermal velocity.For the heating feature of alcohol burner, for the firing rate of the liquid beyond improving in the middle part of flask bottom, the application
Design increased groove, the contact area of the liquid beyond improve in the middle part of flask bottom and thermal source.In still-process,
In bottle, liquid is integrally difficult to keep same temperature, and localized liquid Temperature Distribution is different, can be doped with difference in the liquid fractionating out
The liquid of boiling point.In order that the liquid firing rate in bottle is uniformly, so that temperature is consistent, the design of the application will be recessed as far as possible
Groove radius is designed as 1.75 times of the radius of groove so that the contact area of liquid beyond in the middle part of flask bottom and thermal source
More than the liquid in the middle part of flask bottom, compensate for alcohol burner single-point heating defect so that liquid is further held in together in bottle
One temperature, improves the quality of fraction.
Brief description
Fig. 1 is structural representation of the present utility model；
Fig. 2 is present invention looks up structural representation of the present utility model；
In figure: 1 is flask body, 2 is horizontal ends, 3 is fractionating column, 4 is groove, 5 is groove, 6 is heating pole.
Specific embodiment
The technical characterstic of the present invention is expanded on further below in conjunction with the accompanying drawings with specific embodiment.
This utility model is a kind of flask of homogeneous heating, and including flask body, flask body is hemispherical, flask body
Bottom be provided with horizontal ends, horizontal ends be round sheet；The sidepiece of described flask body is provided with a fractionating column, point
Evaporate Guan Weiyi tubular pipe, the axis of tubular pipe of fractionating column and horizontal ends place plane are in 47 degree of angles；Described water
One hemispheric groove is provided with flush end, the radius of groove is the 1/8 of horizontal ends radius, the centre of sphere of groove and level
The end upper surface center of circle is same point；The hemispheric groove of some uniform arrangements is provided with described horizontal ends, all of recessed
Groove is ringwise arranged with the centre of sphere of groove for the center of circle；The radius of described groove is 1.75 times of the radius of groove；Described
The centre of sphere of groove is the 1/2.37 of horizontal ends radius to the distance of the centre of sphere of groove；It is provided with heating pole on described groove,
Heating pole is perpendicular to horizontal ends.The thickness of described horizontal ends is 2.45 times of flask sidewall thickness.
The utility model has the advantage of the drawbacks of it can overcome prior art, reasonable in design novelty.The application's
Design arranges some grooves by increasing a groove at the middle part of horizontal ends and outside groove.The setting of groove is just
Flame to alcohol burner, in heating process, increased the contact area of the liquid in the middle part of flask bottom and thermal source, improves and add
Thermal velocity.For the heating feature of alcohol burner, for the firing rate of the liquid beyond improving in the middle part of flask bottom, the application's
Design increased groove, the contact area of the liquid beyond improve in the middle part of flask bottom and thermal source.In still-process, bottle
Interior liquid is integrally difficult to keep same temperature, and localized liquid Temperature Distribution is different, can be doped with different boilings in the liquid fractionating out
The liquid of point.In order that liquid firing rate in bottle uniformly, makes temperature be consistent as far as possible, the design of the application is by groove
Radial design is 1.75 times of the radius of groove so that the liquid beyond in the middle part of flask bottom is big with the contact area of thermal source
Liquid in the middle part of flask bottom, compensate for alcohol burner single-point heating defect so that in bottle liquid be further held in same
Temperature, improves the quality of fraction.
Certainly, described above is not to restriction of the present utility model, and this utility model is also not limited to the example above, this
The those of ordinary skill of technical field, in essential scope of the present utility model, change, remodeling, interpolation or the replacement made, all
Protection domain of the present utility model should be belonged to.
