Description
Technical field
The utility model is mainly concerned with the sample making apparatus field of coal, refers in particular to the saturating formula drying equipment of a kind of wind with blowing clearly function.
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, selective (not necessarily artificial) the sample that runs off be that sample making course is definitely unallowed.
For the dry run of coal sample, current existing dehumidification mode mainly contains two kinds:
(1) air natural dries mode: which can not change the mass property of coal, but efficiency is too low, chronic (being generally 24 ~ 48 hours), and occupied ground is larger.
(2) hot blast and large oven for drying mode: which carries out the dry dehumidification of coal sample with high-power heating lamp or high-power baking oven.This kind of mode is not because analyze two stages of the mass transfer of dehumidification process, and moisture evaporation is only carried out on material surface, and the material of internal layer is difficult to evaporate moisture, and the air on material surface is once the water absorption that reaches capacity, and would not suck moisture again.The air on surface is not if taken away in time or taken a breath, and in fact moisture evaporation can stop.Therefore which can not too fast dehumidification, and efficiency equally can be very low, and the time can be very long.Because baking oven uses conventional fan, air exchanging rate is slow, and scavenging efficiency is low, and the air in case therefore can be made close to saturated water suction, and therefore the efficiency of use oven drying high-moisture material can be very low.
There is practitioner to further provide a kind of drying proposal based on the saturating mode of wind, namely utilize hot blast to penetrate material, make material complete dehumidification.But often there is following problem in traditional this equipment:
1) automaticity is not high, and equipment does not possess purging, clearing function, and each cleaning needs manual operation, and operator's labour intensity is large.
2) as manually cleaned not in time, one is the dry dehumidification work that screen tray blocking can affect lower batch, causes efficiency to decline, equipment energy consumption is high, and two is possible cause the residual accumulation of coal sample, and inside is unclean and then pollute the coal sample of lower batch, make coal sample of low quality, accuracy is inadequate.
3) can not automatically monitor screen tray service condition, screen tray then may be caused to block as manually cleaned not in time or changing, the service life affecting equipment even causes security incident.
Prior art is compared, and the utility model has the advantage of:
1, the utility model structure is simple, easy to operate, has automatic blowing cleaning function, and device interior is cleaned, and can not impact the sample of rear batch, dehumidification efficiency is high, and sample accuracy is high.
2, the utility model reduces the labour intensity of operator, and equipment energy consumption is low, and service life of equipment is longer.
3, the utility model automatization level is high, can automatically monitor screen tray service condition, reminds clean or changes screen tray, enhancing job security.
