ABSTRACT:
BACKGROUND OF THE INVENTION
The invention relates to an apparatus for converting discharged air into a rotary force.
Air blasts are used in many ways such as for cleaning and compressing. However, few concepts and technologies have been developed for using the air once blasted for other purposes.
The object of this invention is to generate a rotary driving force by the use of ascending air bubbles formed by injecting air into a liquid.
SUMMARY OF THE INVENTION
According to the present invention, the rotary driving apparatus comprises at least one rotatably mounted turbine wheel or screw submerged in a liquid, preferably water, and a gas introducing means for introducing gas into the liquid, arranged below the turbine wheel or screw, for forming gas bubbles which contact the vanes of the turbine wheel or screw surface whereby the turbine wheel or screw surface is caused to rotate.
In a preferred embodiment, the rotary driving apparatus which uses air bubbles for rotation comprises a multiplicity of rotatable turbine wheels arranged one above the other supported to be rotatable about a horizontal axis by sides of a liquid tank having an air inlet at the bottom thereof and an air outlet at the top thereof; multiple vanes of each turbine wheel being curved or bent so that ascending air bubbles contact the inner enclosed surface of each vane, the multiple turbine wheels or propellers being interlocked to each other by means of gears, a chain or a belt, and the like.
In a second preferred embodiment, the rotary driving apparatus which uses air bubbles for rotation comprises at least one vertically arranged screw turbine wheel or propeller having a shaft rotatably supported at the top and the bottom by the top and bottom ends of a liquid holding tank, the liquid holding tank having an air inlet at the bottom thereof and an air outlet at the top thereof, the screw turbine wheel or propeller being arranged so that ascending bubbles contact a surface of the screw, turbine wheel or propeller.
