Abstract A cleaning system for cleaning cylinrical filters includes a housing having an opening on one side thereof, a motor driven turntable for supporting a filter to be cleaned, a plurality of spray nozzles selected to provide spray at predetermined heights and at predetermined distances from the perimeter of the filter to be cleaned, a high pressure pump for supplying cleaning fluid to the cleaning nozzles and first and second rinse nozzles, the first rinse nozzle being adjustable in both the vertical and horizontal directions relative to the filter to be cleaned, the second nozzle being horizontally adjustable to clean the bottom pan of the filter to be cleaned, the first and second rinse nozzles being connected to a water source at normal main pressure. Each of the external wash nozzles above a predetermined height from the bottom of the filter being individually controllable to provide a proper wash spray for optimum cleaning of a filter. The exterior wash nozzles being connected to a common conduit and being adjustable as a unit in the horizontal direction relative to the filter to be cleaned.
Apparatus for cleaning filters, comprising: An enclosed housing; a rotary turntable mounted within said housing for supporting said filter to be cleaned; A first spray mechanism having a plurality of washing nozzles for washing an interior surface of said filter; A second spray mechanism positioned to clean an exterior surface of said filter, the position of said second spray mechanism being adjustable relative to said first spray mechanism and to said exterior surface of said filter; Means for rotating said turntable and; Means for supplying a washing liquid at a pressure above main pressure to said first and second spray mechanism.
