Abstract
An aerating propeller for attaching to the end of a drive shaft includes blades having a chamber to receive a flow of fluids from a conduit in a drive shaft. A trailing face of the blade includes a first opening into the chamber to permit the flow of fluids in the chamber to exit the propeller and a tip of the blade includes a second opening extending into the chamber to permit the flow of fluids in the chamber to exit the propeller. The first opening of the first blade is aligned generally in the same plane with the leading face of the second blade which follows the first blade when the propeller is rotated.
Claims23
A submersible mixing propeller for dispersing and mixing a fluid in a liquid, the propeller having an axis of rotation, comprising:
- (a) an input for receiving a flow of fluid;
- (b) first and second blades having a pressure side, suction side, tip, root section, leading face and a trailing face,
- (c) a chamber communicating with the input for receiving the flow of fluid from the input;
- (d) the trailing face comprises a first opening extending into the chamber to permit the flow of fluid in the chamber to exit the propeller;
- (e) the tip comprises a second opening extending into the chamber to permit the flow of fluid in the chamber to exit the propeller;
- (f) the suction side is angled from a plane perpendicular to the axis of rotation in a direction toward the pressure side when moving from the leading face to the trailing face;
- and
- wherein the first opening of the first blade is aligned generally in the same plane with the leading face of the second blade which follows the first blade, when the propeller is rotated.
An submersible mixing propeller adapted to be rotated about a central axis, comprising:
- (a) an intake;
- (b) a plurality of hollow propeller blades radially extending outwardly from the central axis and connected to the intake, the propeller blades having a pressure side, suction side, tip, root section, leading face and a trailing face;
- (c) the pressure side is oriented at an angle from a plane perpendicular to the axis of rotation in a direction toward the suction side when moving from the leading face to the trailing face;
- (d) the suction side is oriented at an angle from a plane perpendicular to the axis of rotation in a direction toward the pressure side when moving from the leading face to the trailing face;
- (e) a first discharge opening in the trailing face;
- (f) a second discharge opening in the tip;
- wherein the trailing face of a first blade is aligned generally in the same plane with the leading face of the second blade which follows the first blade such that when the propeller is rotated in use liquid exiting the discharge opening of the first blade is struck by the leading edge of the second blade;
- and wherein the angled orientations of the pressure side and the suction side cause an axial flow of the water in which the propeller is submersed.
