Description
Technical field
Present invention relates generally to the sample making apparatus field of coal, refers in particular to the saturating formula drying equipment of wind that a kind of band blows clearly function.
Background technology
For coal analysis, actually a kind of process of sampling analyses.Coal is a kind of uneven material（Granularity,
Mass property distribution etc.）, the female parent being sampled is typically than larger（Tens tons are arrived tens of thousands of tons）, being extracted into greatest extent can generation
The process of the representative sample of the whole female parent quality of table and characteristic has mechanical sampling, artificial sample, half machinery at present " sampling "
The various ways methods such as sampling.Every country has pressure standard, it is necessary to carry out sampling work in accordance with standard.
Adopt after sample by standard, next process is sample preparation, and the criterion of sample making course is not destroy sample representativeness
Under the premise of, sample granularity is gradually reduced, quality is also gradually reduced, until meeting granularity and quality of the laboratory assay to sample
（Weight）Require.The processes such as sample making course is typically air-dried, crushes, division, pulverizing.It is air-dried（Also can heat drying,
But temperature should be less than 50 DEG C）Process is to reduce sample exterior moisture, and the broken and division process being beneficial to below is normally carried out.System
Crush during sample is the process reduced by sample granularity.Division process is the process for typically being subtracted matter to sample,
The part sample of reduction must be able to represent the Coal Characteristics of sample before reducing, and division process is also to complete sample in sample making course
The process that amount is reduced, during other, standard regulation should be not allow for coal sample loss.Because the sample loss of non-division process（Such as
Coal dust is lost in, and spoil is selected）, the Coal Characteristics of the sample, selectivity can be changed（It is not necessarily artificial）Ground is lost in sample
Product are that sample making course is absolutely not allowed.
For the dry run of coal sample, existing dehumidification mode mainly has two kinds at present：
（1）Air dries mode naturally：Which will not change the mass property of coal, but efficiency is too low, and the time is very long（One
As be 24～48 hours）, and occupied ground is larger.
（2）Hot blast and big oven for drying mode：Which is carrying out coal sample with high-power heating lamp or high-power baking oven
It is dried dehumidification., because not being analyzed to two stages of the mass transfer of dehumidification process, moisture evaporation is only in material for this kind of mode
Surface is carried out, and the material of internal layer is difficult to evaporate moisture, and the air of surface of material once reaches saturated water adsorptive value, would not be again
Suction moisture.If do not taken away in time or being taken a breath, moisture evaporation can actually stop the air on surface.Therefore which will not be too
The dehumidification of fast ground, efficiency equally can be very low, and the time can be very long.As baking oven uses conventional fan, air exchanging rate is slow, ventilation effect
Rate is low, therefore the air in case can be made to be close to saturation water suction, therefore the efficiency using oven drying high-moisture material can be very
Lowly.
There is practitioner to further provide a kind of drying proposal based on the saturating mode of wind, i.e., material is penetrated using hot blast, make
Material completes dehumidification.But, often there is problems with traditional this equipment：
1）Automaticity is not high, and equipment does not possess purging, clearing function, and cleaning manually need to be operated every time, operator's labor
Fatigue resistance is big.
2）Clean as artificial not in time, one be screen tray blocking can under the influence of batch be dried dehumidification work, cause under efficiency
Drop, equipment energy consumption are high, and two is to be likely to result in coal sample residual accumulation, and internal unclean and then to lower batch coal sample is polluted,
So that coal sample is of low quality, accuracy is inadequate.
3）Screen tray service condition can not be monitored automatically, screen tray blocking is likely to result in if manually cleaning not in time or changing,
The service life of impact equipment even causes security incident.

53, can not only 360 degrees omnidirection blow clearly, moreover it is possible to while realize lifting blow clearly, rotation plus lifting by way of, the scope blown clearly
It is wider, blow clearly effect more preferable so that device interior is cleaned, dehumidification efficiency high reduces the labor intensity of operator, equipment energy consumption
Low, service life of equipment is longer.Further, the present invention is by arranging side Qing Chui mechanisms 7 so that can either be from screen tray component 4
Just blown in the face of which clearly, can blow clearly the another side of screen tray component 4 again, two-sided to blow clearly effect more preferably, screen tray component 4 is more
Cleaning, will not impact to the sample of rear batch, and dehumidification is in hgher efficiency, and sample degree of accuracy is high.
In the present embodiment, test and be additionally provided with 2 cavity of chamber 1 or blanking chamber for detecting the pressure reduction of 4 vapour lock of screen tray component
Sensor 9.By differential pressure pickup 9 come automatic detection screen tray screen cloth zero load vapour lock, periodic replacement screen tray is pointed out, sieve is not resulted in
Disk is blocked, and reduces the generation of security incident.
The above is only the preferred embodiment of the present invention, protection scope of the present invention is not limited merely to above-described embodiment,
All technical schemes belonged under thinking of the present invention belong to protection scope of the present invention.It should be pointed out that for the art
For those of ordinary skill, some improvements and modifications without departing from the principles of the present invention should be regarded as the protection of the present invention
Scope.
