TURBINE FOR AN UNDERWATER AERATOR

摘要

The disclosure describes a turbine for use in an underwater aerator; it comprises a cylindrical body, the upper side of which displays an annular hub and an annular recess while the lower side of which displays a circular central recessed area. A first series of air passageways traverses the body from the inner wall of the annular recess to the outer wall of the body while a second series of fluid passageways traverses the body from the central recessed area to the outer wall of the body. Each air passageway defines an exit opening which is located immediately downstream from a fluid exit opening defined by each passageway whereby during rotation, a vacuum is created drawing air into the body of water.
