Abstract
A fluid agitating apparatus is disposed in a vessel containing a body of fluid to be agitated. The fluid agitating apparatus includes a housing having an inlet at an open lower end thereof, and an outlet at an open upper end thereof, with a flow passage disposed through the housing communicating the inlet and the outlet. The flow passage is preferably circular in cross-section and has a minimum diameter at a throat thereof. The diameter of the flow passage increases continuously from the throat toward both the inlet and the outlet. A vertically upward directed nozzle is located in the flow passage below the throat for inducing flow of fluid from the body of fluid in which the housing is submerged into the inlet and upward through the flow passage. A tangentially directed nozzle is disposed in the flow passage above the throat for inducing a swirling flow in the fluid flowing upward through the flow passage. This creates a swirling vortex type flow exiting the outlet of the housing which provides agitation of the body of fluid in which the apparatus is submerged. Covers are provided in the corners of the vessel to prevent deposition of sediment at those corners. Additional nozzles extend through a wall of the vessel near the bottom thereof for agitating a lower portion of the body of fluid adjacent the bottom of the vessel.
