In addition, the utility model is not directly contacted with tested ore pulp, securely and reliably, convenient for gas defence, explosion-proof, anti-pollution;And certainly with temperature
Dynamic compensation function, measurement accuracy are better than 0.2%.
Belt conveyor will be sent into through broken, screening raw coal in drum sieve in batcher, and the mounted angle of cylinder is 8 °~
10 °, drum sieve inside is with the helical blade rotated clockwise, the inverse time under drum sieve is driven by the retarder of motor institute band
Needle rotates, and is supplied water to cylinder interior by Pulp pump, raw coal dipping and heaving during cylinder rotates, and in the effect of flow
Down so that the powder material in raw coal is mixed with water generates suspension, to playing suspension effect by washed coal.
Make to be suspended by washed coal and by density and granularity sedimentation layering, the material that density is big during cylinder rotates is transported
Dynamic speed is fast, therefore when material layering, the big spoil of density is fallen in helical blade, the small cleaned coal material of density upper, with
The impact of flow and go out discharge port, and spoil then by helical blade, gradually from upper end, take out of during rotation by discharge port.
Dirt band bone coal under spoil sieves after spoil sieve screening is further processed through cyclone, and the overflow of cyclone is through cash
The further screening of stone sieve, so cycle reduce the loss of coal.After preliminary washing, the material of drum sieve lower end discharge port passes through
Straight line dehydration and vibration sieve is crossed further to rinse and screened by certain particle size, satisfactory material under the action of medium water

Ore pulp in stirring container 6;Vacuum extractor 3 is opened, the bubble in slurry is extracted, reaches to close after vacuum level requirements and vacuumizes
Device 3;Agitating device 2 stops stirring, and ultrasonic signal measuring device 4 starts to measure the acoustical signal in container 6, and will measure
Acoustical signal is sent to ultrasonic signal processing device 5 and is handled, and measures slurry density.
Due to the hysteresis quality adjusted in technical process, the bound of density of setting value, and 3 etc. are respectively divided into bound
Grade is selected corresponding when surveyed density value is in the upper limit or lower range according to the density rating range where its density
Valve opening, it is contemplated that adjust the lossy to executing agency in real time, fixation is all made of when Media density is in range once
Valve opening.
In terms of metering, the weighing-up wave of belt conveyer scale is accessed in the Analog input mModule of PLC and be computed and obtain weight
Measure information, feeding and load measured by pan feeding belt conveyer scale and outfeed belt scale, to coal washing workload and
Quantity of cleaned coal is measured, while carrying out statistical appraisal to coal quality.
