ABSTRACT:
Dry polymer is fed from a hopper into the funnel-shaped path of a mixing structure which has upper and lower nozzle portions cooperating to define a frustoconical nozzle opening or eductor which provides communication between the path and a surrounding annular chamber. Water is delivered along the side of the chamber so that it swirls through the nozzle opening and is ejected into the funnel-shaped path in a conical swirling stream which mixes with dry powder falling along the path and forms a Venturi to draw the powder along the path. The swirling mixture is injected into the top of a vertical rotating tube which extends down into a container and carries an elongated hollow impeller at its lower end. The water polymer mixture is further mixed in the tube and sprayed through the impeller into an upper mixing compartment of the container. Liquid is drawn through openings in the bottom of the impeller to facilitate the mixing action. The mixture is then passed to a lower aging compartment, from which it is fed to auxiliary mixing and diluting means. Control means prevents feeding of the dry polymer in the absence of the conical water stream.
