Abstract
The present invention provides a system and method for providing a self-cleaning water circulation system which may be utilized for a fish pond, fountain, or the like. Means for automatically cleaning the pump intake to avoid pump failure due to leaves and debris is provided. The circulation system also comprises a self-cleaning filter for cleaning the circulated water whereby maintenance requirements are substantially reduced.
Claims22
A self-cleaning filter assembly for filtering circulated liquid, said self-cleaning filter assembly being connectable with a source of pressurized liquid, comprising:
- a filter for filtering unfiltered liquid to produce filtered liquid, said filter collecting waste when filtering said liquid;
- a filter cleaning member for directing said pressurized liquid onto said filter for cleaning said filter to produce waste fluid, said waste fluid comprising said waste collected when filtering said liquid;
- and
- a pivotally mounted liquid director member, said pivotally mounted liquid director member being pivotal to a first pivotal position for selectively directing said waste fluid towards a waste liquid outlet, said pivotally mounted liquid director member being pivotal to a second pivotal position for selectively directing said filtered liquid to a filtered liquid outlet.
A self-cleaning filter assembly for use with a controllable source of pressurized fluid, comprising:
- a filter for filtering fluid to produce filtered fluid, said filter collecting debris while filtering said fluid;
- a piston and a cylinder moveable between a first position and a second position, said piston and said cylinder being in fluid communication with said controllable pressurized fluid and responsive to said controllable pressurized fluid for relative movement of said piston and said cylinder between said first position and said second position, said piston and cylinder being operatively mounted for directing said filtered fluid to a filtered fluid outlet in said first position, said piston and cylinder being operatively mounted for directing a waste fluid comprising said debris towards a waste fluid outlet in said second position.
A self-cleaning filter assembly for use with a source of pressurized filter cleaning fluid, comprising:
- a filter;
- a housing with said filter mounted therein, said housing defining an unfiltered inlet for receiving unfiltered fluid to be filtered with said filter to thereby produce filtered fluid, said filter collecting debris when producing said filtered fluid;
- one or more nozzles mounted within a filter housing, said one or more nozzles being oriented to produce rotating motion of said pressurized filter cleaning fluid within said filter housing for removing said debris from said filter to thereby clean said filter;
- and
- one or more outlets in said housing.
A method for producing filter media comprising:
- obtaining a pre-fluid processed mass of fiber;
- fluid processing said pre-fluid processed mass of fiber by spraying fluid thereon to produce a fluid processed mass of fiber wherein said fluid processed mass of fiber binds itself together so as to have significantly increased cohesiveness as compared to said pre-fluid processed mass of fiber;
- and
- utilizing said fluid processed mass of fiber in a filter housing for filtering fluid.
