Description
Technical field
This utility model is related to a kind of beaker of quick heating, belongs to teaching equipment field.
Background technology
Beaker is a kind of common laboratory glassware, is generally made up of glass, plastics or heat resistant glass.Beaker
In cylinder, the side at top has a notch, is easy to pouring liquid.Some beaker outer walls are further marked with scale, can be rough
Estimate beaker in liquid volume.When classroom instruction is demonstrated, the thermal source due to classroom instruction typically adopts existing beaker
Alcohol burner, but the temperature of alcohol burner is relatively low, and thermal source is not concentrated, thus result in firing rate slow so that class demonstration
Overlong time, have impact on teaching 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 one kind and quickly adds
The beaker of heat, accelerates the progress of heating, improves the efficiency of class demonstration.
For solving above-mentioned technical problem, this utility model adopts the technical scheme that, a kind of beaker of quick heating, including
Interior beaker body and outer beaker body, interior beaker body and outer beaker body are cylinder, and interior beaker body is socketed in outer beaker body, interior burning
Cup and the coaxial setting of outer beaker body, are provided with upper end capping between the top edge of interior beaker body and outer beaker body；Described interior
Heating sheet metal is provided with the outer surface of beaker body, heating sheet metal is arranged in the outer surface of interior beaker body in cylindrical helical
On, the pitch of the cylindrical screw of heating sheet metal is the 1/4 of the height of interior beaker body, the spiral shell of the cylindrical screw of heating sheet metal
Swing angle is 27.5 degree；The lower end of described heating sheet metal is connected with collector metal cover, and collector metal cover is arranged at outer beaker body
On the lower surface of inner surface；It is provided with coolant perfusing hole in the capping of described upper end, coolant perfusing hole is provided with sealing plug,
It is provided with cavity in sealing plug, the upper and lower surface of sealing plug is provided with through hole.
Optimize, the beaker of above-mentioned quick heating, the lower surface of described outer beaker body is provided with arc groove, metal collection
Heat cover is arranged on the upper surface of arc groove and is arranged with the form fit of the upper surface of arc groove.
Optimize, the beaker of above-mentioned quick heating, the radian of described arc groove is 2.75.
The utility model has the advantage of the drawbacks of it can overcome prior art, reasonable in design novelty.The application's
Design, by beaker body and outer beaker body in setting, serves heat-insulated effect, but in heating, outer layer beaker body also can be by
Heating, so inconvenient teacher picks up beaker, at this moment can irrigate coolant so that outer beaker body is cold by coolant perfusing hole
But conveniently pick up to observation of students.In order to improve the efficiency of heating surface, the design of the application arranges on the outer surface of interior beaker body and adds
Thermometal piece, heating sheet metal is in that cylindrical helical is arranged, and such setting enables to interior beaker body and is heated evenly, improves
The hotter uniformity, and increased the contact area of interior beaker body and thermal source, improve firing rate.Draw through experiment,
The pitch of the cylindrical screw of heating sheet metal is the 1/4 of the height of interior beaker body, the helical angle of the cylindrical screw of heating sheet metal
During for 27.5 degree, heats are preferable.The setting of collector metal cover and arc groove can concentrate the heat of alcohol burner, reduces
Scattering and disappearing of the heat of alcohol burner, further increases the efficiency of heating surface.
Brief description
Fig. 1 is structural representation of the present utility model；
In figure：1 is interior beaker body, 2 is outer beaker body, 3 is upper end capping, 4 is heating sheet metal, 5 is collector metal cover,
