Abstract
An aerator or destratifier used to provide Oxygen to standing or less active bodies of water. The aerator has a non-floating internally driven motor within a non-floating sealed drum. The drum and motor are supported by a support frame attached to floatation devices. A plurality of elliptically shaped paddles are externally affixed to the exterior surface of the non-floating drum. Rotation of the drum by the internal motor and gearbox causes rotation of the plurality of paddles affixed to the drum exterior. The plurality of paddles cause agitation of the body of water and allow Oxygen to be dissolved therein.
Claims12
An aerator or destratifier for a liquid medium comprising:
- an environmentally sealed drum having a first and second end and a continuous side surface there between;
- a stationary shaft extending from said first and second ends;
- a plurality of paddles affixed to the exterior surface of said continuous side surface of said drum;
- at least one floatation device;
- a motor and gearbox for driving said drum, mounted internally of said drum;
- a support frame for supporting said drum on the floatation device;
- and
- a power supply for supplying power for driving said motor.
An aerator or destratifier for a liquid medium comprising:
- an environmentally sealed drum having a first and second end and a continuous side surface there between;
- a stationary shaft extending from said first and second ends;
- a plurality of paddles affixed to the exterior surface of said continuous side surface of said drum;
- at least one floatation device;
- a motor and gearbox for driving said drum, mounted internally of said drum;
- a support frame for supporting said drum on the floatation device;
- and
- a power supply for supplying power for driving said motor;
- said internal motor and said gearbox are mounted on said stationary shaft;
- said stationary shaft extends through said first and said second ends of said drum, and including sealed bearings on said first and said second ends for supporting said stationary shaft;
- said support frame includes support shaft receptors, said stationary shaft received therein;
- said support frame includes fastening devices said floatation devices secured to said support frame thereby;
- said plurality of paddles are affixed to said continuous side surface in a staggered sigmoidal pattern;
- said paddles are perforated;
- said paddles are elliptically shaped, said elliptical shape formed by progressive bends in said paddles;
- said paddles have a series of generally fan shaped bends;
- said paddles are wider at the base and narrower at the ends.
A method of aerating or destratifying a liquid by mounting aerator paddles in a sigmoidally staggered pattern to the exterior of a sealed internally driven drum containing a motor and geardrive within it, wherein said paddles are elliptical and perforated, the aeration or destratification comprising the steps of;
- electrical operation of the motor mounted internally within the drum, wherein the motor turns the gears of the geardrive, which in turn rotates the sealed drum;
- rotation of said elliptical and perforated paddles through the liquid medium, thereby causing the liquid medium to be agitated and exposed to increased levels of the gaseous medium surrounding the liquid medium, and wherein the liquid medium is agitated causing mixing of stratified bands.
