A kind of heating water bath equipment with steady rest
Technical field
The present invention relates to a kind of heating water bath equipment with steady rest, belong to teaching equipment field.
Background technology
Water is first added in a bulk container, then the container to be heated is put into and is added in the container of water.Heating is filled with water
Bulk container by heating the water in bulk container again by water heat transfer(Heat transfer)Need in the container that heats, reach plus
The purpose of heat.Because in normal atmosphere pressure and water is without any impurity, the condition that water reaches boiling point is 100 degrees Celsius, still
From liquid change to gaseous state also need to absorb higher heat.In immersion method, the water in beaker all can only before vapor is become
There is 100 degrees Celsius of temperature, more heats can not be provided for the water in test tube, so invisible spectro liquid is to seethe with excitement
's.So heating water bath usually is carried out to some reactions for needing constant temperature to heat using this temperature immovable principle.But
Under normal circumstances, the medium of water-bath is used as using tap water.Contain the metallic compounds such as calcium and magnesium sodium in tap water, after the heating,
Incrustation scale can be formed on the surface of container is heated, it is difficult to clean.
The content of the invention
In view of the deficienciess of the prior art, the technical problem to be solved by the invention is to provide one kind to carry steady rest
Heating water bath equipment, easy to use, firing rate is fast.
In order to solve the above technical problems, the present invention adopts the technical scheme that, a kind of heating water bath with steady rest is set
It is standby, including water bath;The water bath includes groove body, and cover board is provided with groove body, boss, water-bath are provided with the edge of cover board
Groove is provided with the boss groove coordinated with boss with cover board junction, and sealing ring is provided with boss groove;It is provided with the cover board
Some equally distributed circular through holes, steady rest is provided with circular through hole, and the upper edge of steady rest is higher than the upper surface of cover board;
Some snorkels are provided with the steady rest, snorkel is taper, and the taper of snorkel is 1:2.35, the inner surface of steady rest
On be provided with some arc-shaped protrusions, the radian of arc-shaped protrusions is 2.14.
Optimization, the above-mentioned heating water bath equipment with steady rest, the steady rest is hemispherical glass plate, water bath
It is raised that some heating are provided with lower surface.
The advantage of the invention is that it can overcome the drawbacks of prior art, novelty reasonable in design.The design of the application
Tap water is held using water bath, container to be heated is positioned over steady rest, alcolhol burner is heated in water bath lower part, because
To have held tap water in water bath, so the surface temperature of water bath is not above 100 degree, and heat container to be added not with water
Directly contact, prevent from forming incrustation scale in vessel surface to be heated.In order to the setting of steady rest play the role of stable flask must, make
It is stable and firm in heating process to obtain flask, will not skew because of the impact of the water and steam of boiling.Arc-shaped protrusions will be burnt
Depart from after bottle holder height with steady rest surface, snorkel exports the steam in water bath, directly by steam injection and the table of flask
Face, so can improve firing rate by steam heating, and increase the uniformity of heating.
Brief description of the drawings
Fig. 1 is the structure diagram of the present invention;
Fig. 2 is the structure diagram of the steady rest of the present invention;
In figure:1 it is groove body, 2 be cover board, 3 be boss, 4 be boss groove, 5 be steady rest, 6 be snorkel, 7 is that arc is dashed forward
Rise, 8 be heating protrusion.
Embodiment
Below in conjunction with the accompanying drawings with the specific embodiment technical characterstic that the present invention is further explained.
The present invention is a kind of heating water bath equipment with steady rest, including water bath;The water bath includes groove body, groove
Cover board is provided with body, boss is provided with the edge of cover board, water bath is provided with convex with boss cooperation with cover board junction
Platform groove, is provided with sealing ring on boss groove;Some equally distributed circular through holes are provided with the cover board, are set in circular through hole
Steady rest is equipped with, the upper edge of steady rest is higher than the upper surface of cover board;Some snorkels, snorkel are provided with the steady rest
For taper, the taper of snorkel is 1:2.35, some arc-shaped protrusions, the radian of arc-shaped protrusions are provided with the inner surface of steady rest
For 2.14.The steady rest is hemispherical glass plate, and it is raised that some heating are provided with the lower surface of water bath.
The advantage of the invention is that it can overcome the drawbacks of prior art, novelty reasonable in design.The design of the application
Tap water is held using water bath, container to be heated is positioned over steady rest, alcolhol burner is heated in water bath lower part, because
To have held tap water in water bath, so the surface temperature of water bath is not above 100 degree, and heat container to be added not with water
Directly contact, prevent from forming incrustation scale in vessel surface to be heated.In order to the setting of steady rest play the role of stable flask must, make
It is stable and firm in heating process to obtain flask, will not skew because of the impact of the water and steam of boiling.Arc-shaped protrusions will be burnt
Depart from after bottle holder height with steady rest surface, snorkel exports the steam in water bath, directly by steam injection and the table of flask
Face, so can improve firing rate by steam heating, and increase the uniformity of heating.
Certainly, it is limitation of the present invention that described above, which is not, and the present invention is also not limited to the example above, the art
Those of ordinary skill, in the essential scope of the present invention, the variations, modifications, additions or substitutions made, should all belong to the present invention
Protection domain.
