Abstract
The utility model belongs to the heating device field specificly provides a muffle furnace. This muffle furnace include the furnace body and with furnace body lateral wall articulated furnace gate, still be equipped with the observation window between furnace body and the furnace gate, the observation window with the bottom of furnace body is articulated. The utility model discloses a set up the observation window, the the experimenter of being convenient for observes the disposition of sample, and can not cause the furnace body inside thermal lost, the furnace gate is crisscross with the opening direction of observation window, reducible thermal forfeiture, the opening of observation window upwards can avoid the interior hot gas flow direct -flushing of furnace body human, guarantees the experimenter's safety. The utility model discloses be suitable for and popularize and apply in the laboratory.
Description
Technical field
This utility model belongs to heater field, and concrete provides a kind of Muffle furnace.
Background technology
Muffle furnace is a kind of heating tool that laboratory is conventional, it is generally the case that in heating process, fire door all closes, and some needs to observe the heated condition of sample after experiment heating a period of time, now, if opening fire door, in stove, steam can quickly overflow, and damages human body.
Utility model content
The purpose of this utility model is to overcome drawbacks described above, it is provided that the Muffle furnace of a kind of safe and convenient observation.
The technical solution of the utility model: a kind of Muffle furnace, including body of heater and the fire door hinged with sidewall of the furnace body, is additionally provided with observation window between described body of heater and fire door, described observation window is hinged with the bottom of described body of heater.
The setting of observation window, it is simple to experimenter observes the disposition of sample, and does not results in scattering and disappearing of furnace interior heat；Fire door interlocks with the opening direction of observation window, can reduce the forfeiture of heat；The opening upwards of observation window, in can avoiding body of heater, thermal current flings human body, it is ensured that the safety of experimenter.
Preferably, first heat-insulation layer being formed around outwardly convex of described observation window, the medial surface of described fire door is provided with the second heat-insulation layer, and described second heat-insulation layer intermediate projections surrounding is low to match with the first heat-insulation layer.The setting of Double insulating layer, changes plane contact into curved face contact, can reduce the forfeiture of heat.
Preferably, described observation window top is provided with handle, it is simple to opened by observation window.
Preferably, described observation window is made up of pyroceram.
Preferably, described body of heater top is provided with air vent, and described air vent is connected with defecator by exhaustor.It is then exhausted from after adding thermogenetic gas filtration, reduces environmental pollution.
Preferably, described defecator is active carbon filter.
Preferably, described defecator is activated silica filter.
Preferably, described defecator is lower big little prismatoid, increases contact area, more effectively absorbs harmful gas.
Preferably, between described air vent and defecator, it is additionally provided with blower fan, the discharge of gas can be accelerated.
This utility model advantage: 1, the setting of observation window, it is simple to experimenter observes the disposition of sample, and does not results in scattering and disappearing of furnace interior heat.
2, fire door interlocks with the opening direction of observation window, can reduce the forfeiture of heat.
3, the opening upwards of observation window, in can avoiding body of heater, thermal current flings human body, it is ensured that the safety of experimenter.
4, the setting of defecator, can reduce noxious gas emission, reduce environmental pollution.

Drawing reference numeral in figure is: 1-body of heater, 2-fire door, 3-observation window, 4-the first heat-insulation layer, 5-the second heat-insulation layer, 6-handle, 7-air vent, 8-blower fan, 9-exhaustor, 10-active carbon filter, 11-activated silica filter.
Detailed description of the invention
Below in conjunction with specific embodiment, this utility model is expanded on further.
A kind of Muffle furnace, including body of heater 1 and the fire door 2 side walls hinged with body of heater 1, is additionally provided with observation window 3 between described body of heater 1 and fire door 2, described observation window 3 is hinged with the bottom of described body of heater 1.First heat-insulation layer 4 being formed around outwardly convex of described observation window 3, the medial surface of described fire door 2 is provided with the second heat-insulation layer 5, and described second heat-insulation layer 5 intermediate projections surrounding is low to match with the first heat-insulation layer 4.First heat-insulation layer 4 is arranged over handle 6.Described observation window 3 is made up of pyroceram.
Described body of heater 2 top is provided with air vent 7, and described air vent 7 is arranged over blower fan 8, and blower fan 8 is connected with defecator by exhaustor 9.Described defecator is lower big little prismatoid, including the most spaced active carbon filter 10 and activated silica filter 11.
This utility model is by arranging observation window 3, it is simple to experimenter observes the disposition of sample, and does not results in scattering and disappearing of furnace interior heat；Fire door 2 interlocks with the opening direction of observation window 3, can reduce the forfeiture of heat；The opening upwards of observation window 3, in can avoiding body of heater, thermal current flings human body, it is ensured that the safety of experimenter.Additionally, the gas that Muffle furnace heating process produces discharges after defecator filters again, environmental pollution can be reduced.
Should be understood that these embodiments are merely to illustrate this utility model rather than limit scope of the present utility model.In addition, it is to be understood that after having read the content that this utility model is lectured, those skilled in the art can various modifications may be made or changes to this utility model, and these equivalent form of values fall within the application appended claims limited range equally.
