Technical field
The invention belongs to thermal testing field, relate to the visual heat sink that a kind of atmosphere is controlled, this device can make sample completely cut off air to lower the temperature in nitrogen, ensures that sample constituents is constant.
Background technology
The tests such as the heating instruments such as Muffle furnace are common instruments very important again in scientific research, and they are used to for industrial and mining enterprises, and the heat treatment of small-sized steel part is done by R&D institution, and the one-tenth of the high-temperature heating of metal, pottery etc. and living beings, coal dust is grey.
Generally, test specimen is warmed up to a certain high temperature in heating instrument, then can keep certain hour, to meeting the requirements of state or completing the reaction of anticipation.Afterwards, close heating instrument, sample is lowered the temperature voluntarily in atmosphere.But this exists some problems, analyzed by xrd and find, if the ash that Muffle furnace obtains after burning living beings is directly lowered the temperature in atmosphere, can steam be infected with in composition, increase a lot of crystallization water.Visible, directly lower the temperature in atmosphere, sample may with the reactions such as the oxygen in air, steam, cause result of the test inaccurate.
For this reason, researcher is a lot of effort of having avoided these problems to do.
Application number be 200910103149.1 Chinese invention patent disclose a kind of cool-down method of electrical heating vertical furnace, this INVENTION IN GENERAL is for open several cooling holes in burner hearth bottom gap, when electric furnace blowing out is initial, inject a large amount of nitrogen in chamber to play the effect reducing temperature and density of hydrogen.When density of hydrogen drop to safety value once time, stop nitrogen injection, change air injection.The method can by the control realization of air mass flow to the control of burner hearth cooling rate.
Application number be 201020268318.5 Chinese invention patent disclose a kind of nitrogen quick-cooling device for high-temperature carbonizing furnace, this device comprises nitrogen circulation blower fan, nitrogen cooling cavities and nitrogen circulation pipeline.High temperature carbonization furnace is offered one group of nitrogen input/output port, high temperature carbonization furnace, nitrogen circulation blower fan, nitrogen cooling cavities are connected on nitrogen circulation pipeline, realize cooling to high temperature carbonization furnace by circulating of nitrogen.
A kind of controlled nitrogen fast cooling device (Yang Lingdong. controlled nitrogen fast cooling device [J]. Anhui Electronic Information Professional Technology College's journal, 2008, (01): 46-47,51), this device is the special-purpose assorted equipment of the development in order to coordinate superlaser to test.Package unit system is made up of gas circuit and electrical control two large divisions.Gas circuit is made up of pressure-reducing valve, surge flask, the parallel combined gas circuit, reative cell etc.; Electric control system gathers andlogic control circuit and PC, Display panel and keyboard by pressure sensor, flow sensor, temperature sensor, signal transformation circuit, modulus, power lights forms.This device can make high-temperature laser wafer drop to normal temperature in the shortest time from more than 300 DEG C, but as can be seen from part, compared with the cooling object that will realize, this apparatus design is too complicated, easy not.
As can be seen from above prior art, at present for the heat treatment of small-sized steel part, at the device of particular atmosphere borehole cooling after the one-tenth ash of the high-temperature heating of metal, pottery etc. and living beings, coal dust, what have needs transformation heating instrument, perforate is carried out to it, some system complex, cost is higher, and this is all unfavorable for realizing the cooling of sample under specific atmosphere easily.Therefore, design one is simply easy to realize, and guarantee test sample is not by air impact in temperature-fall period, and the device of components unchanged is necessary.
Summary of the invention
A kind of high temperature sample of can avoiding is the object of the present invention is to provide to react with the composition such as the oxygen in air and steam in temperature-fall period, to ensure the visual heat sink that atmosphere that sample constituents does not change before and after cooling is controlled.
For achieving the above object, the technical solution used in the present invention is: comprise the casing that top is provided with cover plate, and the inside of described casing is provided with and housing interior volume is divided into upper and lower two-part gas permeable barrier; Described lower box space is filled with drier; The side opening of casing is provided with the air inlet communicated with space on casing and the gas outlet communicated with lower space.
Described gas permeable barrier offers the aperture of some guarantee air current flow.
Described casing and cover plate are made up of transparent quartz glass.
Described cover plate has the temperature detection hole for connecting temperature measuring device and then the change of monitoring test sample temperature.
The contact surface of described casing and cover plate adopts frosted process.
The contact surface of described casing and cover plate is coated with seal grease.
Described cover plate is provided with a handles.
The present invention is by being provided with for carrying the test specimen needing cooling at the box house with cover plate, and desiccant-filled in the space of lower box, the steam in suction means, and guarantee test sample, in the process of cooling, does not have the participation of moisture; Simultaneously body side offers gas inlet and outlet, then by before lowering the temperature in test specimen embedding device, passes into nitrogen, discharged by the air in device from gas outlet through gas feed in device; Continue during cooling to pass into nitrogen, ensure test specimen and air exclusion in temperature-fall period, avoid the oxygen in itself and air and steam to react completely, ensure the components unchanged before and after sample cooling.
