Abstract
A self cleaning filter includes a body ( ), inlet ( ), outlet ( ), flush inlet ( ) and waste outlet ( ). Elements ( ) provide filtration while compressed but are cleaned decompressed. Feed from inlet port ( ), impacts and swirls from an impeller ( ) on moveable plunger ( ) for preliminary centrifugal separation. During filtration plunger ( ) is positioned to open the inlet port ( ), the filtrate port ( ) and compress filtration elements ( ). The swirling feed permeates the filtration elements ( ) and passes filtrate port ( ), filtrate valve ( ), filtrate plenum ( ), and exits the filtrate outlet ( ). Plunger ( ) is moved and cleaning is provided by supplication of pressurized cleaning media to the back flush receiver plenum ( ) via the back flush media inlet ( ). This pressure motivates plunger( ) to close inlet port ( ), filtrate port ( ) and decompress filtration elements ( ). Multidirectional jets ( ) and ( ) of cleaning media exits orifices ( ) and ( ) to flush the filtration elements ( ) in an optimal multidirectional fashion. Waste is discharged from waste outlet ( ).
