Abstract:
A water pressure aeration device comprised of:a water pump equipped with two pipes that respectively convey the pumped water, of which a small pipe conveys water to a water filtering basin and another large outlet pipe conveys water under pressure to a water distribution head; said water distribution head consists of a round cover that is connected to the end of said outlet pipe by a rotated thread and washer fastening means; said water distribution head cover has a number of short tubular connector fittings, with the fittings along an outer periphery of said cover being relatively short, while the tubular connector fitting at the center section of said cover is longer to facilitate installation; a cavitation housing that is a T-shaped tubular fixture having at the bottom section a low planar stabilizer appendage; a water distribution tube is connected to one end of said tubular fixture, means forming a rear pressure constrictive opening is disposed posteriorly inside said cavitation housing, with a facing spray guide element inclined downward and situated between a fresh air intake opening of a vertically connected fresh air supply tube and said means for forming said rear pressure constrictive opening; said guide element is approximately one-third the distance away from the nearest end of the fixture, thereby functioning to increase pressure of the water column flowing through said, water distribution tube at said rear constrictive opening and, furthermore, said spray guide element deflects the water column downward; a front pressure constrictive opening is formed in said tubular fixture anterior to a spray nozzle; and a mixture chamber is formed in between said front and rear pressure constrictive openings such that after the water column flows through said rear pressure constrictive opening and passes both said spray guide element and the fresh air supply tube opening, fresh air is drawn into said mixture chamber and swirled into a cavitated wash and then discharged from said spray nozzle into the water of a pond or tank for utilization; an air filter and delivery device consisting of an air filter and delivery device float situated on the underside that enables stable buoyancy on the surface of the water; an air filter housing is installed on said float that contains a horizontally placed activated carbon filter screen element, at the upper section of which is an air intake opening, an outer dust filter screen hood, a top protective cover, an air filter and delivery device decorative object, and a threaded shaft is inserted through the middle of the air filter and delivery device secured with a nut to fasten the assembled structure of the air filter and delivery device.
