ABSTRACT:
A mixing system which prevents accumulation of buoyant stagnant particles on the liquid surface and produces substantially uniform outlet slurry concentrations, comprising a tank having partial baffles in combination with an agitator. The baffle designs may be suitable for variable or constant level tanks depending upon the particular design selected and basically includes a plurality of baffles located within the tank substantially at or just below the liquid surface. These baffles are spaced about the tank wall and for a constant level agitated tank can be secured to the wall at a fixed location. In the case of variable level tanks the baffles can be maintained at the desired location by means of a floating member.
Another embodiment locates the baffles as mentioned above and further provides a centrally located draft tube located above the agitator. Still another embodiment for variable level tanks locates narrow fixed baffles extending substantially from the liquid surface to the bottom of the tank.
