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 weighing automatic air desiccated balance device for sample preparation.
Background technology
For coal analysis, be actually a kind of process of sampling analysis.Coal is a kind of inhomogeneous material (granularity, mass property distribution etc.), the female parent of being sampled is larger (tens tons to several ten thousand tons are not waited) generally, be extracted into to greatest extent the process of the representative sample that can represent whole maternal quality and characteristic " sampling ", the various ways methods such as mechanical sampling, artificial sample, half mechanical sampling are arranged at present.Every country all has the pressure standard, must abide by standard and carry out sampling work.
After adopting sample by standard, next process is sample preparation, and the criterion of sample making course is under the prerequisite of not destroying sample representativeness, and sample granularity is reduced gradually, and quality also gradually reduces, until meet laboratory assay to granularity and quality (weight) requirement of sample.Sample making course generally is the processes such as free air dry, fragmentation, division, abrasive dust.Air dry (but also heat drying, but temperature should be less than 50 ℃) process is to reduce the outside moisture of sample, and the fragmentation and the division process that are beneficial to the back are normally carried out.Fragmentation is the process that sample granularity is reduced in the sample making course.The division process is the process that sample is subtracted typically matter, the Coal Characteristics of sample before the part sample that reduces must be able to represent and reduce, the division process also is to finish the process that sample size reduces in the sample making course, and other process Plays regulations should not allow the coal sample loss.Because the sample loss of non-division process (run off such as coal dust, spoil be selected etc.), can change the Coal Characteristics of this sample, selectivity (not necessarily artificial) sample that runs off is that sample making course is definitely unallowed.
Coal sample needs before powder process or before the bottling sample is carried out heat drying and air balance processing.At present, generally adopt total man worker's mode of operation: the transfer of sample needs manual intervention, and dry and equilibration time needs the artificial memory.If when processing a plurality of sample simultaneously, exist easily mixed sample, drying and equilibration time to hold the problems such as inaccurate, that the hand labor amount is large.
