Description
Technical field
The present invention relates to material moisture detection and granularity Detection field, and in particular to a kind of more physical and chemical performance on-line measuring devices of material
And its detection method.
Background technology
In metallurgy industry, it is necessary first to the moisture in supplied materials is accurately detected, then according to water content detection value come control material
Moisture so that material moisture is maintained at during subsequent technique in a rational scope.The real-time detection of material moisture is to most
Yield and quality and the energy consumption index influence of finished product are very big, only quick and precisely detect the moisture of material, could realize accurate control.
Equally, the granularmetric composition change of original supplied materials, not only influences granulating efficiency, with greater need for matching suitable work during subsequent technique
Skill parameter, the yield and quality index and energy consumption of final products not so can be influenceed because of the change of mixture ventilation.As can be seen here, it is right
Original supplied materials moisture and granularmetric composition are used for quickly detecting the key technology that analysis is metallurgy industry.
In existing metallurgy industry, original supplied materials moisture and granularmetric composition detection are usually manual sampling, send laboratory to carry out detection point
Analysis, water content detection are detected using loss on drying, and granularmetric composition detection uses sieve method, because being unable to on-line checking, Wu Fashi
Now automatically control, and testing result seriously lags, and causes the reduction of production efficiency.In terms of water content detection, on-line checking
Mode is typically detected using infrared moisture meter and microwave moisture instrument etc., belongs to non-contact type measuring device, existing main
Problem is that measurement is inaccurate, and cost is high, maintenance of equipment trouble and difficulty complicated, therefore that moisture can be caused to control, enters one
Step causes the unstable of yield and quality index and energy consumption.
The U of Publication No. CN 201607382, publication date are on October 13rd, 2010, and entitled " one kind is used to detect material water
Point device " patent document disclose a kind of determination of moisture method, this method by using microwave drying principle, using cylinder
Body rotating disk carries out the structure design of vertical rotary relative to microwave generating apparatus, and the blast furnace material that big grade has been effectively ensured is quickly equal
Dry evenly.But the technology can only carry out offline inspection in laboratory, and mainly for the drying of large granular materials, it is impossible to
Meet the needs of on-line quick detection.The Y of Publication No. CN 201382888, publication date is on January 13rd, 2010, entitled
The patent document of " Potable grain composition measuring instrument " discloses a kind of assay method of raw meal particle size composition, this method by using
Multiple canonical measure sieves are superimposed from top to bottom, and the measurement that raw meal particle size forms can be realized with rapid and convenient.But the technology can only be

Influence, it is therefore desirable to analysis is used for quickly detecting to supplied materials, with Instructing manufacture, especially as original iron ore powder, coke powder and coal dust
Deng material, often changing a batch just needs to detect moisture and the granularmetric composition of its supplied materials, currently used for detection material moisture and granularity group
Into method be mainly manual sampling, deliver to laboratory and tested and analyzed, water content detection is mainly weighting method after dried, can also
Using infrared and microwave moisture instrument on-line checking, but inaccuracy is measured, precision is not high；Granularmetric composition detection is then that sampling is delivered to
Laboratory, it is classified using sieve method, the material of each sieve is weighed respectively after the completion of screening, calculates its granularity group
Into, wet feed sieving time length, and screen cloth is easily blocked, moisture distribution also has a certain impact to quality testing.It is artificial in addition
Long the time required to sampling detection and analysis, human cost is high.With raising of the metallurgy industry to production automation level requirement, and
The further reinforcement of intelligence manufacture theory, manual sampling detection material moisture and granularmetric composition mode can not meet high yield,
Efficient and high automated production demand.
