Description
Technical field
The utility model is mainly concerned with the sample making apparatus field of coal, refers in particular to a kind of scalable temperature measuring equipment for coal sample dehumidifying device.
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.
By standard, adopt after sample, 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 laboratory assay to the granularity of sample and quality (weight) requirement.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 ℃) 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 of matter that sample is subtracted typically, 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, selectivity (not necessarily artificial) sample that runs off is that sample making course is definitely unallowed.
For the dry run of coal sample, current existing dehumidification mode mainly contains three 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 is not because analyze two of the mass transfer of dehumidification process stages, and moisture evaporation is only carried out on material surface, and the material of internal layer is difficult to evaporate moisture, once and the air on the material surface water absorbing capacity 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, so uses the efficiency of oven drying high-moisture material can be very low.
(3) adopt hot-air through type coal sample dehumidifying device: it comprises casing, controller and blower fan, dividing plate, gas heater, dividing plate is separated into two chambers by casing, on dividing plate, be placed with a coal sample dish that is used for above splendid attire coal sample, the bottom of coal sample dish offers more than one air vent, utilize gas heater to add hot-air, then by blower fan, hot-air is sent on coal sample dish the coal sample on coal sample dish is carried out to quick dehumidification operation.
Above-mentioned the third mode, due to the dehumidification mode that has adopted hot blast to penetrate, has effectively increased the evaporation surface of coal sample, and efficiency can improve several times to decades of times, has improved the accuracy of sample preparation.But existing equipment has the following disadvantages: in dehumidification operation process, often will carry out Real-Time Monitoring to the temperature of coal sample in charging tray and charging tray thereof, to complete efficiently, accurately, reliably dehumidification operation.In order to realize Real-Time Monitoring, what generally adopt is the form that hangs temperature sensor in dehumidification operation chamber, and the mode that still hangs sensor often causes accuracy of detection not high, cannot reach best monitoring effect.
Utility model content
The technical problems to be solved in the utility model is just: the technical matters existing for prior art, the utility model provides a kind of simple and compact for structure, with low cost, easy and simple to handle, measuring accuracy is high, practicality is good scalable temperature measuring equipment for coal sample dehumidifying device.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind of scalable temperature measuring equipment for coal sample dehumidifying device, comprise temperature element, in the movement travel of one end of described temperature element sample dish in coal sample dehumidifying device, also can contact with sample dish, the other end of described temperature element is connected so that temperature element self-return with an elastic recoil assembly.
As further improvement of the utility model:
Described elastic recoil assembly comprises the guide rod that slide block, are above, and described slide block is slidedly arranged on guide rod, between the end of described guide rod and slide block, is provided with retracing spring, and described temperature element is connected on slide block and with slide block and moves on guide rod.
Described slide block, guide rod, retracing spring are all installed in shell, and one end of described guide rod is fixed on the inwall of shell, and the other end is fixed on guide rod fixed head.
Compared with prior art, the utility model has the advantage of: the scalable temperature measuring equipment for coal sample dehumidifying device of the present utility model, simple and compact for structure, with low cost, easy and simple to handle, measuring accuracy is high, practicality good, temperature element can remain directly follows the tracks of contact temperature-measuring to filling the sample dish of coal sample, this thermometric mode measured temperature can more level off to tests Shi coal seam temperature, thereby has improved accuracy of temperature control.
