Description
Technical field
The utility model is mainly concerned with the sample making apparatus field of coal, refers in particular to a kind of coal sample dehumidifying device that adopts hot-air through type.
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 being sampled is larger (tens tons to several ten thousand tons not etc.) generally, be extracted into greatest extent the process of the representative sample that can represent whole maternal quality and characteristic " sampling ", have at present the various ways methods such as mechanical sampling, artificial sample, half mechanical sampling.Every country all has pressure standard, must 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 under the prerequisite of sample representativeness, sample granularity is reduced gradually, and quality also gradually reduces, until meet granularity and quality (weight) requirement of laboratory assay to sample.Sample making course is generally the processes such as free air dry, fragmentation, division, abrasive dust.Air dry (also can heat drying, but temperature should be less than 50 DEG C) process is to reduce the outside moisture of sample, and the fragmentation and the division process that are beneficial to below are normally carried out.In sample making course, fragmentation is the process that sample granularity is reduced.Division process is the process that sample is subtracted typically to matter, the Coal Characteristics of sample before the part sample reducing must be able to represent and reduce, division process is also in sample making course, to complete the process that sample size reduces, and other process Plays regulations should not allow coal sample loss.Because the sample loss of non-division process (as coal dust runs off, spoil be selected etc.), can change the Coal Characteristics of this sample, the selective sample that runs off (not necessarily artificial) is 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, and chronic (being generally 24～48 hours), and occupied ground is larger.
(2) hot blast and large oven for drying mode: which is to carry out the dry dehumidification of coal sample with high-power heating lamp or high-power baking oven.This class mode because not two stages of the mass transfer to dehumidification process analyze, moisture evaporation is only carried out on material surface, the material of internal layer is difficult to evaporate moisture, once and the air on the material surface water absorption that reaches capacity, just can not suck again moisture.The air on surface is if do not taken away in time or take a breath, and in fact moisture evaporation can stop.Therefore not dehumidification too soon of which, efficiency equally can be very low, and the time can be very long.What use due to baking oven is conventional fan, and air exchanging rate is slow, and scavenging efficiency is low, therefore can make the air in case approach saturated water suction, therefore uses the efficiency of oven drying high-moisture material can be very low.
Have practitioner to propose a kind of hot-air through type coal sample dehumidifying device, comprise casing and be installed in blower fan, dividing plate, the gas heater in airtight casing, casing is separated into two chambers by dividing plate, is respectively bottom chamber and top chamber.Blower fan is arranged in top chamber, and this blower fan adopts air exhauster.On dividing plate, be placed with a coal sample dish that is used for above splendid attire coal sample, coal sample paves uniformly in coal sample dish.The bottom of coal sample dish offers more than one air vent, and hot-air flow passes from air vent, sees through uniformly coal sample, and coal sample is carried out to dehumidification operation.But prior art as above described in structure, is all to adopt single heat form, and only carries out the heating of air-flow in bottom chamber, then will utilize thermal current to carry out dehumidification to coal sample.The deficiency of this form is just: 1. the form of single heating, heat up slower, and greatly reduce dehumidification efficiency; 2. while carrying out repeatedly operation, for the first time with operation gap for the second time during, heater is out-of-work, now the temperature of charging tray also can sharply decline, and repeats again to heat up inefficiency while carrying out operation for the second time; 3. in whole dehumidification operation, the target of heating should be the coal sample on charging tray and charging tray, the mode that above-mentioned existing structure does not directly heat both, and target is concentrated not and is clear and definite, causes efficiency not high enough.
Utility model content
The technical problems to be solved in the utility model is just: the technical problem existing for prior art, the utility model provides a kind of simple and compact for structure, easy and simple to handle, saturating formula drying box of the wind with auxiliary heating that can improve dehumidification efficiency and dehumidification quality.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
The saturating formula drying box of a kind of wind with auxiliary heating; comprise casing and be installed in the charging tray in casing, main heating component, charging tray supporting component; described charging tray is installed on charging tray supporting component, and described coal sample paves uniformly in charging tray, and the hot blast that described main heating component produces blows to charging tray; Also comprise more than one auxiliary heating assembly, described auxiliary heating assembly is installed in casing.
As further improvement of the utility model:
Box house is divided into two chambeies by described charging tray supporting component, and described charging tray is arranged in a cavity, and described main heating component is arranged in another cavity, and described auxiliary heating assembly is installed in the cavity at charging tray place in casing.
The outside of described auxiliary heating assembly is provided with auxiliary heating separation net.
Described charging tray supporting component is provided with black box.
Described auxiliary heating assembly near and install around charging tray.
Described auxiliary heating assembly away from charging tray and be adjacent to casing madial wall install.
Compared with prior art, the utility model has the advantage of: the saturating formula drying box of the wind with auxiliary heating of the present utility model, simple and compact for structure, easy and simple to handle, can improve dehumidification efficiency and dehumidification quality; The utility model adopts the form of auxiliary heating, like this in the time heating, utilizes the auxiliary heating assembly preset temperature that just can be rapidly heated, and charging tray is carried out to preheating, and in the overall process of heating, to continue to keep the temperature of charging tray be the temperature of setting.Even, in the time of drying experiment for the second time, charging tray can be warmed up to preset temperature faster, further improves overall dehumidification efficiency.
