Description
Technical field
The utility model is mainly concerned with the gathering and processing of material samples, analytical equipment field, and in particular to a kind of sample drying
Device.
Background technology
For material（Such as ore, coal charge）Sample gather and process, analyze work, every country has pressure standard, it is necessary to abide by
Sighting target standard carries out gathering and processing sample and analysis work.The criterion that the course of work was gathered and processed, analyzed to sample is not destroy sample representativeness
Under the premise of, collected sample granularity is gradually reduced, quality also gradually reduces, until meeting grain of the laboratory assay to sample
Degree and quality（Weight）Then required precision carries out relevant analysis of experiments to satisfactory sample.It cannot during this
Enough there is the loss of sample, can not enable sample that some occur and physically or chemically change, otherwise final test result will be made
At influence.
Such as by taking coal charge is analyzed as an example, actually a kind of process of sampling analysis.Coal is a kind of non-uniform substance（Grain
Degree, mass property distribution etc.）, what is be sampled is maternal general bigger（Tens tons are differed to tens of thousands of tons）, it is extracted into the maximum extent
The process of the representative sample of entire maternal quality and characteristic can be represented " sampling ", there is mechanical sampling, artificial sample, half at present
The various ways method such as mechanical sampling.After adopting sample by standard, next process is sample preparation, and sample making course generally has air dry
The processes such as dry, broken, division, milling.Sample makes the laggard sampling test analysis for carrying out next step.Coal gather and process sample and
In analytic process, can using to moisture measurement instrument with to the moisture of coal sample carry out analysis of experiments.The moisture of coal is evaluation
Coal Economy is worth most basic index.Because the variation of moisture in coal can cause changes of contents and the calorific value of other components
Variation, to the certain influence of the generations such as the inspection matter of coal, metering, examination, management.Therefore, life of the Accurate Determining moisture in coal to coal
