  • Sanitary rotary tank cleaning apparatus
    Patent number: 11154918
    Abstract: A rotary tank cleaning spray nozzle assembly which includes a stationary housing, a rotary housing for rotation about a central axis of the stationary housing, and a nozzle carrying hub supported by the rotary housing for rotation about an axis transverse to the axis of the stationary housing. A support rod extends through the rotary housing and into the stationary housing with a lower end supporting the underside of the rotary housing and the upper end being secured by a retainer. The retainer is releasable to permit removal of the rotary housing and nozzle hub from an underside of the stationary housing. A fluid driven drive for the rotary housing and nozzle hub includes a pair of removably mounted bevel gear rings. In one embodiment, liquid lubricating, frustoconical, high load carrying bearings support rotatably.
