Liquid intake filters
Apparatus and methodologies are provided for pumping fluids from a body of fluids. Herein, an apparatus operably connected to at least one pump for pumping fluids from a body of fluids is provided, the apparatus having a pump hose with a first intake end for receiving the pumped fluids and a second outlet end operably connected to the pump, a pump intake assembly, fluidically connected to the intake end of the pump hose, the pump intake assembly having at least one fluid control valve, a rotatable filter cage, centrally disposed about the pump intake assembly, and at least one fluid injection pipe centrally disposed within the pump hose for supporting the at least one fluid control valve, and for injecting fluids to drive the rotation of the rotatable filter cage. Herein, methods of utilizing the fluid pumping apparatus are provided.
1. A fluid pumping apparatus operably connected to at least one pump for pumping fluids from a body of fluids, the apparatus comprising:
a pump hose having a first intake end for receiving the pumped fluids and a second outlet end operably connected to the pump,
a pump intake assembly, fluidically connected to the intake end of the pump hose, the pump intake assembly having at least one fluid control valve,
a rotatable filter cage, disposed about the pump intake assembly and about a central vertical operational axis of the pump hose, and
at least one fluid injection pipe centrally disposed within the pump hose for supporting the at least one fluid control valve, and for injecting fluids to drive the rotation of the rotatable filter cage.
2. The apparatus of claim 1 , wherein the pump intake assembly further comprises a conical inlet.
3. The apparatus of claim 1 , wherein the at least one fluid control valve comprises an annular check valve actuable between open and closed positions.
4. The apparatus of claim 3 , where in the annular check valve may be slidingly positioned about the at least one fluid injection pipe.
5. The apparatus of claim 1 , wherein the filter cage contains a plurality of apertures to form a perforated filter cage.
6. The apparatus of claim 5 , wherein the filter cage further comprises at least one flange extending inwardly from one or more of the plurality apertures.
7. The apparatus of claim 5 , wherein the filter cage further comprises at least one filter device for filtering debris from pumped fluids.
8. The apparatus of claim 1 , wherein the apparatus further comprises at least one propeller having a plurality of blades for enhancing rotation of the filter cage.
9. The apparatus of claim 1 , wherein the at least one fluid injection pipe comprises at least one spray nozzle.
10. The apparatus of claim 1 , wherein the apparatus is adjustably supported by one or more floatation devices.
11. The apparatus of claim 10 , wherein the one or more floatation devices are inflatable.
