Description
Technical field
The utility model relates to a kind of food experiment teaching temperature control stirring device.
Background technology
In food experiment teaching, temperature control stirring device is one of instrument demonstration instrument often used, but current temperature control stirring reaction unit needs reaction bulb to be placed in oil bath or cold hydrazine, make reaction bulb outside with wet goods, affect the clean of experimental bench and laboratory, be unfavorable for the carrying out of testing; And the cold and hot gap of glass reaction device is large easily cracked.
Utility model content
The utility model provides a kind of food experiment teaching temperature control stirring device, and it is little that it has volume, conveniently moving, and experimentation cleans, heat transmission is quick fully, prevent cracked advantage.
To achieve these goals, the utility model adopts following technical scheme:
Temperature control stirring device is used in a kind of food experiment teaching, comprise internal layer there-necked flask, glass outer and feet, internal layer flask and glass outer are at there-necked flask three bottleneck sealings by fusing, temperature control liquid flow chamber is formed between internal layer flask and glass outer, glass outer top arranges temperature control liquid outlet, temperature control liquid entrance is set exporting offside bottom position with temperature control liquid, temperature control liquid outlet and temperature control liquid entrance arranged outside non-slip process, can effectively prevent connecting hose slippage, bottom glass outer, sealing by fusing has the feet of three elliposoidals, feet be hollow and be provided with passage.
The beneficial effects of the utility model:
1. this device temperature control liquid can access from temperature control liquid entrance, flow to there-necked flask top around there-necked flask to flow out from temperature control liquid outlet, temperature control liquid flow chamber can be full of temperature control liquid, there-necked flask bottle is made to immerse in temperature control liquid, sufficient contact surface is provided, makes heat transmission more fast fully.
2. temperature control liquid is sealed in temperature control liquid flow chamber, whole glass reaction device before the reaction after and course of reaction in all removable, temperature control liquid can not be excessive, ensure test sanitation and hygiene, be beneficial to carrying out smoothly of experiment.
3. put into magneton in flask, then this glass device is placed in magnetic agitation, this glass device and magnetic agitation and oil bath pan (or cold hydrazine etc.) reaction of temperature control magnetic agitation can be carried out.Also temperature control stirring reaction is realized by mechanical agitation.
4. temperature control liquid can make conduction oil, alcohol, water etc., the temperature control liquid of access different temperatures can heat up to system and also can lower the temperature, what can circulate passes into temperature control liquid, avoids the appearance of side reaction or the impurity caused due to the carrying out local temperature change of reaction.
5. many this glass reaction devices individual can carry out the accurate parallel reaction of identical temperature control, identical stirring.
6. temperature control liquid outlet and temperature control liquid entrance arranged outside non-slip process, can effectively prevent connecting hose slippage.
7. bottom glass outer, sealing by fusing has the feet of three elliposoidals, feet be hollow and be provided with passage, feet effectively can reduce the contact area with desktop, prevents glass outer and desktop etc. from contacting local temperature difference chipping greatly.
8. passage effectively can regulate gas temperature and pressure inside and outside feet, makes feet stable connection, not easily broken.
Accompanying drawing explanation
Fig. 1 is temperature control three mouthfuls of glass reaction apparatus structure schematic diagrames;
Wherein, 1. flask, 2. glass outer, 4. temperature control liquid flow chamber, 5. feet, 6. passage, 7 temperature control liquid entrances, 8. temperature control liquid outlet, 9. non-slip process.
Detailed description of the invention
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
As Fig. 1, temperature control stirring device is used in a kind of food experiment teaching, comprise internal layer there-necked flask 1, glass outer 2 and feet 5, internal layer flask 1 and glass outer 2 are at there-necked flask 1 three bottleneck sealings by fusing, temperature control liquid flow chamber 4 is formed between internal layer flask 1 and glass outer 2, glass outer 2 top arranges temperature control liquid outlet 8, temperature control liquid entrance 7 is set exporting 8 offside bottom positions with temperature control liquid, temperature control liquid outlet 8 and temperature control liquid entrance 7 arranged outside non-slip process 9, can effectively prevent connecting hose slippage, bottom glass outer 2, sealing by fusing has the feet 5 of three elliposoidals, that feet 5 is hollow and be provided with passage 6, feet effectively can reduce the contact area with desktop, and passage 6 effectively can regulate gas temperature and pressure inside and outside feet 5, prevent because local temperature difference is chipping greatly.
This device temperature control liquid can access from temperature control liquid entrance 7, flow to there-necked flask 1 top around there-necked flask 1 to flow out from temperature control liquid outlet 8, temperature control liquid flow chamber 4 can be full of temperature control liquid, there-necked flask 1 bottle is made to immerse in temperature control liquid, sufficient contact surface is provided, makes heat transmission more fast fully.Temperature control liquid can be conduction oil, alcohol, water etc., and the temperature control liquid of access different temperatures can heat up to system and also can lower the temperature.Temperature control liquid is sealed in temperature control liquid flow chamber 4, whole temperature control three mouthfuls of glass reaction devices before the reaction after and course of reaction in all removable, temperature control liquid can not be excessive, ensure test sanitation and hygiene, be beneficial to carrying out smoothly of experiment.Can magneton be put in there-necked flask 1, then this glass device is placed in magnetic agitation, also can connect mechanical agitation, composition temperature control stirring reaction unit.This temperature control three mouthfuls of glass reaction devices and magnetic agitation and oil bath pan (or cold hydrazine etc.) reaction of temperature control magnetic agitation can be carried out.There-necked flask 1 three mouthfuls can respectively as the connector of temperature probe, reinforced, condensation, gas with various bag, gas collection bag, mechanical agitation, flowing gas, and these temperature controls multiple three mouthfuls of glass reaction devices can carry out the accurate parallel reaction of identical temperature control (accessing the temperature control liquid of identical temperature), identical stirring (being placed on the agitator of same rotational speed).
By reference to the accompanying drawings detailed description of the invention of the present utility model is described although above-mentioned; but the restriction not to the utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various amendment or distortion that creative work can make still within protection domain of the present utility model.
