DESCRIPTION OF THE PREFERRED EMBODIMENT
With reference now to the drawings, and in particular to FIGS. 1 through 8 thereof, a new combination water pump/air compressor system embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.
As best illustrated in FIGS. 1 through 8, the combination water pump/air compressor system 10 generally comprises a piping configuration including a main pipe 11 capable of carrying combined pressurized air and water, and also including first, second and third extension pipes 45-47 being securely and conventionally connected to the main pipe 11, and further including valve members 12-14 being connected to the extension pipes 45-47. The valve members 12-14 include a water intake valve 12 being securely attached to the first extension pipe 45, and also include a water drainage valve 13 being securely attached to the second extension pipe 46, and further include an air outlet valve 14 being securely attached to the third extension pipe 47.
A water and air pressure accumulator assembly is securely connected to one of the valve members 12-14 and is adapted to be connected to water and air sources for providing pressurized water to the main pipe 11. The water and air pressure accumulator assembly includes a water pressure accumulator 15 having a water reservoir 16 for receiving water from the water source and also having a water valve 17 being securely connected to a water pipe 48 which is conventionally connected to the water pressure accumulator 15 which is conventionally connected to the first extension pipe 45 for introducing water into the main pipe 11 through the first extension pipe, and also includes an air pressure accumulator 18 having an air tank 19 for collecting air from the air source and also having an air valve 20 being securely connected to an air line 49 which is conventionally connected to the air tank 19. The air pressure accumulator 18 is conventionally connected to the water pressure accumulator 15 for pressurizing water received in the water pressure accumulator 15.
An air injector 21 is securely connected to the main pipe 11 for creating air bubbles in the water in the main pipe 11. The air injector 21 is a venturi being securely disposed inline of the main pipe 11 for creating a suction which draws in ambient air into the main pipe 11 thus creating air bubbles in the water in the main pipe 11.
A water and air mixer assembly is securely connected to the main pipe 11 for pressurizing the spongy liquid/gas mixture. The water and air mixer assembly includes an impeller housing 22 being securely connected to the main pipe 11, and also includes a water impeller 23 being securely disposed in the impeller housing 22 and having radial-extended vanes 24 for driving the water in the main pipe 11, and further includes an air impeller 25 having radial-extended vanes 26 for driving the air bubbles in the main pipe 11 with the water and air impellers 23,25 being mounted back-to-back, and also includes an impeller motor 27 being securely connected to the water impeller 23 and to the air impeller 25 for the energizing thereof, and further includes air bleed holes 28 being disposed through a wall of the water impeller 23 and interconnecting the air and water impellers 23,25 for bleeding the air disposed therein and for facilitating the separation of the water and air at a center of the water and air impellers 23,25 with the air and water again being mixed at a periphery of the air and water impellers 23,25. The water impeller 23 and the air impeller 25, in combination, mix and pressure the air and the water together.
A water and air separator assembly is also securely connected to the main pipe 11 for separating pressurized air from pressurized water. The water and air separator assembly includes a water/air centrifuge 30 having vane members 31 for separating the air from the water, and further includes guide ducts 32 which are bell-shaped for directing the water 90 degrees into the main pipe 11, and also includes an air holding tank 33 being securely connected to the water/air centrifuge 30 for receiving the pressurized separated-out air created by the water/air centrifuge 30, and further includes a water turbine 34 being securely connected to the main pipe 11 and having radial-extended vanes for regenerating and re-circulating the water through the main pipe 11 by energizing the water/air centrifuge 30. The water/air centrifuge 30 has O-ring seal members 35 and an elongate duct 36 for slowing down the mixture of water and air to ensure proper centrifugal action upon the water and air mixture. The guide ducts 32 are conventionally disposed between the water/air centrifuge 30 and the water turbine 34 as shown by the dotted lines in FIG. 1.
In FIG. 4, another embodiment includes separated air being tapped from the front of the water/air centrifuge 30 rather than being bled through air bleed holes 41 disposed in a ported hub assembly 37 to the air holding tank 33.
In use, the water and air are introduced into the main pipe 11 through the first extension pipe which is connected to the water and air pressure accumulator assembly, and the venturi 21 creates air bubbles in the water in the main pipe 11, and the water and air impellers 23,25 pressurizes the air and water together to form a spongy liquid/gas mixture which is then passed onto the water/air centrifuge 30 which separates the air from the water with the water being re-circulated back through the main pipe 11, and the air is stored in an air holding tank 33 for use by the user.
As to a further discussion of the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.
Therefore, the foregoing is considered as illustrative only of the principles of the combination water pump/air compressor system. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
