Method and device for mixing oil-containing liquids having multiple viscosities

摘要

A method and device are described for mixing an oil-containing liquid stored in an oil storage tank to determine the monetary value of said oil-containing liquid contained therein. The method comprises rotating an agitating device in the oil-containing liquid; providing a mixed oil-containing liquid; and determining the monetary value of the oil in said oil-containing liquid. The device includes a shaft disposed in the tank and extending along a central axis of the tank. The shaft includes at least one arm structure extending outward from the shaft so that when the shaft is rotated, the arm structure causes the liquid components to be mixed. The shaft is rotated by a power actuating device which may be a fuel powered motor, an electric powered motor a wind turbine or a manual hand crank.
