Background technique
In coal property test industry, wanted in sample making course strict guarantee sample it is representative under the premise of, to sample carry out
Broken and division, until meeting requirement of the laboratory assay to sample granularity and quality, since broken and division equipment is to sample
The adaptability of humidity has certain requirement, therefore coal sample to be dried before.
Each component in coal sample other than moisture removal changes in order to prevent, and temperature when needing to control dry is 50
Degree Celsius hereinafter, also need to prevent simultaneously the case where coal sample loss or mixing occur in dry link, representation of coal sampling is influenced, institute
Mainly coal sample to be dried in the following ways in the prior art:
1, air naturally dry mode: low efficiency, the time is long, occupied ground is big, cannot achieve automation.
2, hot air convective drying mode: thermal current is formed using modes such as warm-air drier or baking ovens, the coal sample of tiling is done
Dry, because dry air cannot be contacted sufficiently with coal sample, and can only rely on the evaporation of moisture, drying efficiency is low, and the time is long.
3, the saturating formula of wind is dry: penetrating the coal sample being laid on sieve using hot wind, comes into full contact with hot wind with coal sample, increases
Evaporation efficiency, but this still can only rely on the evaporation of the following moisture of boiling point, and drying efficiency is not still high, and is easy on sieve
Putty.
Therefore how under the premise of guaranteeing coal sample quality, the drying efficiency of coal sample is improved, is those skilled in the art's urgency
Technical problem to be solved.
