Abstract
A circulator is described that is configured to circulate liquids such as water, chemical mixtures, suspensions and the like. The circulator has an oscillation shaft disposed within, for example concentrically disposed within, a support tube that is used to mount the circulator to a support structure. Locating the oscillation shaft within the support tube makes the circulator more compact, achieves better alignment of the oscillation shaft and the support tube, and makes the circulator stronger compared to a circulator where the oscillation shaft is not disposed within a support tube. In one embodiment, the circulator can be used to create a continuous flow of water in a body of water including around marinas, areas around docks, and waterfronts.
Claims19
A circulator, comprising:
- a support tube;
- an oscillation shaft disposed within the support tube, the oscillation shaft is rotatable relative to the support tube in clockwise and counterclockwise directions;
- a head unit mounted to the support tube, the head unit includes a housing, and an oscillation motor disposed in the housing and having an output drive shaft in driving engagement with the oscillation shaft to drive the oscillation shaft in clockwise and counterclockwise directions;
- and
- a circulation assembly mounted to the oscillation shaft at a lower end thereof, the circulation assembly includes a rotatable propeller, and a drive motor connected to the rotatable propeller to rotate the rotatable propeller.
A liquid circulator for creating liquid circulation in a body of liquid, comprising:
- a support tube configured to be mounted to a support structure;
- an oscillation shaft concentrically disposed within the support tube, the oscillation shaft is rotatable relative to the support tube in clockwise and counterclockwise directions;
- a head unit mounted to the support tube and configured to reside above the liquid, the head unit includes a housing, and an electric oscillation motor disposed in the housing and having an output drive shaft in driving engagement with the oscillation shaft to drive the oscillation shaft in clockwise and counterclockwise directions;
- and
- a liquid circulation assembly mounted to the oscillation shaft at a lower end thereof so as to be oscillated by the oscillation shaft and configured to reside in the liquid to create the liquid circulation, the liquid circulation assembly includes a rotatable liquid propeller, and an electric drive motor connected to the rotatable liquid propeller to rotate the rotatable liquid propeller.
