Abstract
PURPOSE: An operating method in which a solid-rich and highly viscous slurry can be effectively stirred with as much a small stirring power as required for lowly viscous one even at the time of strat.
CONSTITUTION: When transporting a slurry consisting of asphalt as mother liquid and coal as solid content, the starting of the stirrers 4W7 is made at the upper part of the liquid inside the tank 1 because the slurry concentration isdie the tank 1 is lower in the upper part of the liquid and also higher in the lower part. Then, the value α of stirring power is put in the comparator 15 to compare it with the set value β from the setter 13 and then to send out the α-β signal γ to the stroke generator 16 by which, in case where the signal γ is negative, the signal δ to slide downwards the stirrer is sent out to the stroke director 17 in order to gradually slide downwards the stirrer. When it reaches a lower limit, then the signal θ is sent out to the motor 13 through the switch 18 and the timer 19 to strat pumping liquid by the pump 2.
