International Classification:

F04B 5300

US Classification:

417 53, 417 61, 4174239, 210170, 2102422

Abstract:

This circulation device is equipped with a water impeller that is larger than and tightly fitted over the top of the draft tube through which the water from the pond or reservoir is drawn. By placing the impeller above and out of the draft tube it enables to lift water through the draft tube and imparts a centrifugal force on the water above the impeller which aids in moving the water radially outward from the impeller. The water is directed outwardly over a large diffuser plate that is centrally located. The outer edge of the diffuser plate is equipped with a laminar flow diffuser lip which is designed to inhibit the passage of water from the diffuser plate to the open water. This design ensures that most of the energy imparted to the water by the impeller is retained once it leaves the diffuser plate, making the invention operate efficiently.

US Classification:

261 91, 261 93, 261120, 2611221, 2102212, 2102422

Abstract:

One embodiment of an aerator is disclosed that has a hollow intake housing with a horizontally disposed lip on a lower portion thereof. This intake housing converges a flow of bubbles into a draft tube. These bubbles are injected into a fluid in which the aerator is installed at a location that is directly under the intake housing. A fluid flow is also drawn into this draft tube through the intake housing. Fluid exiting the opposite end of the draft tube is directed into a hollow discharge housing having a divergent inner surface. A wave generator (e. g. , a rotating impeller) is mounted within the hollow interior of the discharge housing. The upper end of this discharge housing also includes a horizontally disposed lip to direct a flow out of the aerator at least generally parallel with an upper surface of the fluid.

US Classification:

Abstract:

This circulation device is equipped with a water impeller that is larger than and tightly fitted over the top of the draft tube through which the water from the pond or reservoir is drawn. The water drawn up and directed outwardly over a large diffuser plate that is centrally located within the invention. The outer edge of the diffuser plate is equipped with a laminar flow diffuser lip which is specifically designed to inhibit the passage of water from the diffuser plate to the open water as little as possible. Additionally, a means of providing a floating water circulation apparatus with the ability to operate effectively in weather conditions in which a layer of ice is likely to form over the diffusor plat of the apparatus in the nighttime hours is provided.
