Description
Technical field
The utility model is related to a kind of sample preparation of coal, the powder processed drying in specifically a kind of full-automatic sample preparation of coal
Device, more particularly to a kind of pulverized coal preparation by particle diameter≤3 ㎜ is automatically made into the coal of the coal sampling of particle diameter≤0.2 ㎜
Powder drying unit processed in sample.
Background technology
In the nineties latter stage, the sample making technology of domestic coal is in compared with backward state, and its sample preparation work is basic to rely on people
Work is operated.Domestic Firsts in 1999 integrate the crushing division combined sample making machine group trend of purchasing city for crushing division twice twice
, the consistent accreditation of domestic correspondent is obtained, sample preparation work is freed from cumbersome artificial operation substantially, realize sample preparation
What is worked is semi-automatic；Hand labor intensity is not only alleviated, manual operation error is also partly avoided, sample preparation is improve accurate
Degree.But, its sample preparation needs certain cycle, and needs certain hand labor intensity, and moisture and fine powder lose larger, sample preparation
Precision is difficult to ensure that often there is bias, and, there is the danger for introducing human error, to the coal management work of enterprise
Bring great difficulty.Accordingly, it would be desirable to a kind of automation sample-preparing system for being united each sample preparation program is developed, by one
Determine the coal sampling that the big particulate coal of weight is made constant weight particle diameter≤0.2 ㎜, analyzed to general industry.Full-automatic sample preparation
System is made up of transporting equipment with multiple sample making apparatus.
At present, in domestic offline full-automatic sample-preparing system, by the pulverized coal preparation of particle diameter≤3 ㎜ into particle diameter≤0.2 ㎜
Coal sampling during, usually take the coal dust of 100g particle diameter≤3 ㎜, dried using microwave or infrared drying stove, use
Three flour mill millings of alms bowl formula.But, the coal dusts that three flour mills of alms bowl formula are crushed often tightly be pasted onto bowl inner surface, it is low,
The middle negative method inhaled of pressure can not completely clear up the coal dust for remaining in alms bowl wall, it is necessary to artificial cleaning, is not easy to automation mechanized operation and use
The negative method inhaled collects the coal dust in bowl, and negative suction pipe is easily blocked, and influences the normal operation of equipment.Although and microwave drying is accorded with
Close GB/T19494.2-2004《Coal Mechanicalization sampling part 2：The preparation of coal sample》Standard, but fact proved the coal having
In microwave drying, coal sample has the suspicion for having ature of coal to change after spark phenomenon, and microwave drying.
The content of the invention
The purpose of this utility model be to provide a kind of pulverized coal preparation by particle diameter≤3 ㎜ for conveniently realizing automation mechanized operation into
Powder drying unit processed in the full-automatic sample preparation of coal of the coal sampling of particle diameter≤0.2 ㎜.
The utility model is adopted the following technical scheme that realizes its goal of the invention, the system in a kind of full-automatic sample preparation of coal
Powder drying unit, it includes fan mill, air heater and centrifugal blower, and fan mill is provided with primary discharging opening, discharging opening, enters
Material mouth and hot wind inlet, are connected with return duct, the hot-blast outlet and fan of air heater between primary discharging opening and charging aperture
The hot wind inlet connection of mill, the air outlet of centrifugal blower is connected with the air inlet of air heater.
Due to using above-mentioned technical proposal, the utility model preferably realizes goal of the invention, is crushed using fan mill, empty
Hot-air heater is dried, centrifugal blower air-supply, solves the problems, such as traditional powder manufacturing apparatus material collection hardly possible, sample cross contamination, and
The coal dust being suspended in fan mill chamber is easily heated by the air the heated-air drying of device, it is ensured that its ature of coal is special when various coal dusts are dried
Property will not change.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model powder drying unit.
Specific embodiment
Below in conjunction with the accompanying drawings and embodiment the utility model is described in further detail.
As shown in Figure 1, the powder drying unit processed in a kind of full-automatic sample preparation of coal, it includes fan mill 6, air heater
7 and centrifugal blower 8, fan mill 6 is provided with primary discharging opening 4, discharging opening 3, charging aperture 1 and hot wind inlet, primary discharging opening 4 with
Return duct 2 is connected between charging aperture 1, the hot-blast outlet of air heater 7 is connected with the hot wind inlet of fan mill 6, wind is centrifuged
The air outlet of machine 8 is connected with the air inlet of air heater 7.
The hot-blast outlet of the utility model air heater 7 is connected with the hot wind inlet of fan mill 6 by warm-air pipe 5, from
The air outlet of heart blower fan 8 is connected with the air inlet of air heater 7 by blast pipe 9.
During utility model works, the coal dust of particle diameter≤3 ㎜ enters from fan mill charging aperture 1, and coal dust hits in fan mill
It is crushed under the strike of plate, pulverized coal dust discharges under the blast that beater plate is produced through primary discharging opening 4, because pipeline is prominent
So become big, blast reduction, coal dust of the particle diameter more than 0.2 ㎜ to be returned to continue in fan mill 6 and crushed through return duct 2, particle diameter≤0.2 ㎜
Coal dust be collected through discharging opening 3.In the course of work of fan mill 6, centrifugal blower 8, air heater 7 works, air heating
The hot blast that device 7 is produced to coal dust in the feeding fan mill 6 of warm-air pipe 5 through being dried, because in pulverizing process, coal dust is to suspend
In the chamber of fan mill 6, so, coal dust is easy to be dried, and to also ensure that and dry when drying of coal dust using air heater 7
Between；Meanwhile, when also ensure that various coal dusts are dried conscientiously, its coal characteristic will not change because of link is dried.Work as coal dust
After particle diameter whole≤0.2 ㎜, centrifugal blower 8 is breezed up, and the coal dust blowout that will be remained in the chamber of fan mill 6 is collected, it is ensured that
Fan mill 6 does not remain coal sample in chamber, solves the problems, such as sample cross contamination, meanwhile, can also be by adjusting fan mill 6 with centrifugation wind
The rotating speed of machine 8, adjusts the grinding particle size of coal dust.
