Description
Technical field
The present invention is mainly concerned with the sample making apparatus field that coal sample detects, and refers in particular to a kind of band for sample preparation and weighs automatic air desiccated balance device.
Background technology
For coal analysis, be actually a kind of process of sampling analysis.Coal is a kind of uneven material (granularity, mass property distribution etc.), the female parent be sampled general larger (tens tons to several ten thousand tons not etc.), the process being extracted into the representative sample that can represent whole maternal quality and characteristic to greatest extent, " sampling ", has the various ways methods such as mechanical sampling, artificial sample, half mechanical sampling at present.Every country all has pressure standard, must carry out sampling work in accordance with standard.
After adopting sample by standard, next process is sample preparation, and the criterion of sample making course is under the prerequisite not destroying sample representativeness, and sample granularity is reduced gradually, and quality also gradually reduces, until meet laboratory assay to the granularity of sample and quality (weight) requirement.Sample making course generally has the processes such as air oxygen detrition, fragmentation, division, abrasive dust.Air oxygen detrition (also can heat drying, but temperature should be less than 50 DEG C) process reduces sample exterior moisture, is beneficial to fragmentation below and division process is normally carried out.In sample making course, fragmentation is the process that sample granularity is reduced.Division process is process sample being subtracted typically to matter, the Coal Characteristics of sample before the part sample reduced must can represent and reduce, division process is also the process completing sample size minimizing in sample making course, and other process Plays regulation should not allow coal sample to lose.Because the sample loss of non-division process (as coal dust runs off, spoil is selected), the Coal Characteristics of this sample can be changed, selectivity (not necessarily artificial) the sample that runs off be that sample making course is definitely unallowed.
Coal sample needs to carry out heat drying and air balance process to sample before powder process or before bottling.At present, the full manual mode of operation of general employing: the transfer of sample needs manual intervention, dry and equilibration time needs artificial memory.If when processing multiple sample simultaneously, there is easily mixed sample, drying and equilibration time and hold the problems such as inaccurate, manual labor amount is large.
