  • Patent number: 5899560
    Abstract: A slurry agitation apparatus for selectively agitating slurry temporarily stored in the interior of a storage tank, which slurry contains heavier-than-liquid solids and is at least somewhat pumpable, comprises a slurry circuit having connected together in seriatim, and in fluid communication through pipes one with the next, an outlet disposed in the sump pit in fluid communication with the interior of the storage tank to permit egress of the slurry therefrom, a flow control valve, a selectively controllable slurry pump, and a discharge nozzle. The discharge nozzle is rotatably mounted in surrounding sealed relation on a substantially vertical spigot securely mounted on the concrete foundation of the storage tank, for selective rotation of the discharge nozzle about a substantially vertical main axis, and has a spout portion in fluid communication with the interior of the storage tank and oriented to emit the slurry from the spout portion as a generally horizontally directed discharge.
