Description
Technical field
The present invention is new to be related to a kind of burning sample parameters change analyzer.
Background technology
The measure that parameters change when being burned at present to laboratory sample can only accomplish that the change to temperature and pressure is carried out
Determine simultaneously, go back neither one disposable measurement temperature, pressure, the method for volume simultaneously, measured respectively if repeatedly burn,
Then data error can become big, and increase workload.Temperature, pressure, volume when how accurately and reliably to be burned to test specimen
More item datas are disposably measured, and are a technical problems for being badly in need of solving when burn sample parameters change measure.
The content of the invention
In view of the above-mentioned problems, it is an object of the invention to provide one kind can disposable measurement temperature, pressure, the item data of volume three
Burning sample parameters change analyzer.
One kind burns sample parameters change analyzer, including fastening lid, measurement module, unidirectional oxygenation pipe, igniter, cylinder
Body, it is characterised in that the stack shell upper end is provided with fastening lid, and both are flexibly connected and close to form a closed and external thermal insulation
Combustion chamber, the volume of the combustion chamber can be adjusted by converting the position of fastening lid；The stack shell upper end outer wall side
Volume markings are etched with, the measurement module is provided with temperature sense through being fixedly installed in fastening lid in the measurement module
Device and pressure inductor, through being installed on measurement module, the igniter is installed under measurement module the unidirectional oxygenation pipe
Portion.
Preferably, the measurement module upper surface is provided with numeric display.
Preferably, the measurement module bottom is provided with specimen holder, and the specimen holder is used for placing burning ware.
Preferably, the measurement module upper surface is provided with string holes, from string holes extracting power supply cord.
Preferably, the combustion boat material uses inert metal.
The present invention is provided with the closed combustion chamber of adjustable volume in a creative way, after sample burns in combustion chamber, passes through
The volume of change burning room, the numerical value for making combustion chamber pressure return to before burning, the volume for reading burning indoor gas become
The change numerical value of sample volume parameter can must be burned by changing.
Mechanism of the present invention is simple, easy to operate, disposably temperature, pressure, three parameters of volume can be measured, evaded
Error caused by multiple measurement, effectively increase the accuracy to burning sample parameters change measure.

Embodiment
Below in conjunction with the accompanying drawings, preferred embodiment is elaborated.
As shown in figure 1, when implementing to determine, it should dispose burn sample on specimen holder 6, making burning sample hanging first,
Do not contacted as far as possible with stack shell, produced with stack shell during avoiding sample combustion and direct heat transfer and influence measurement data, if burning sample
Product are smaller or when being liquid, can be put into sample in combustion boat 5, then combustion boat 5 is placed on specimen holder 6 and adjusts burning sample
Grade, which is put, to be allowed to and the end reliable contacts of igniter 4.
Place after burning sample, fastening lid 1 is screwed completely with stack shell 7 by screw thread, now the lower edge of fastening lid 1 and cylinder
The zero point of volume markings 10 on the outer wall of body 7 maintains an equal level.
In addition to using being threadedly coupled, it can also use and determine the connection that the other modes such as journey piston realize fastening lid 1 and stack shell 7.
The power line drawn by string holes 11 connects controlling switch and external power source, and starts measurement module, then passes through
Unidirectional oxygenation pipe 3 is filled with sufficient amount of oxygen into combustion chamber 9, the registration of numeric display 8 is observed after oxygenation, and record its pressure
Force value and temperature value, then by external switch start igniter sample is ignited, if sample calorific value compare your pupil with
It is ignited device 4 to light, then combustion process will produce gas and heat and lime-ash, and the temperature and pressure in combustion chamber 9 all will hair
Changing.After sample burns, this numerical value of two is recorded again after temperature and pressure is stable, then slowly moves up fastening
Lid 1 increases the volume of combustion chamber 9, while observes pressure value, when the numerical value recorded before pressure value is reduced to burning,
Stop mobile fastening lid 1, and record the numerical value of volume markings 10 of the lower edge of fastening lid 1 sensing.
If sample calorific value is than relatively low, it is impossible to is ignited device 4 and lights, then experiment terminates.
Parameter foundation records numerical value and calculated by The Ideal-Gas Equation formula before and after burning sample burns, its
The change of middle heat parameter should subtract igniter ignite sample when the heat that is discharged.
Those listed above is a series of to be described in detail only for feasibility embodiment of the invention specifically
Bright, they simultaneously are not used to limit the scope of the invention, all equivalent implementations made without departing from skill spirit of the present invention
Or change should be included in the scope of the protection.
