CLEANABLE FILTERING DEVICE

摘要

A filtering device (100) is used for liquid. An inlet (102) is fluidly connected to a lower chamber (112). The lower chamber is in free flow fluid communication with an unfiltered region of the upper chamber (110). A filter (124) separates the upper chamber into the unfiltered region and a filtered region. An outlet (104) from the filtered region provides filtered liquid. A drain (106) releases accumulated waste from the lower chamber and waste dislodged from the filter, during a backflush. To filter, pass liquid from the inlet through the lower chamber, in an upward direction to the unfiltered region of the upper chamber, through the filter, into the filtered region and out through an outlet. To backflush, pass liquid from the outlet through the filtered region, through the filter in a reverse direction, into the unfiltered region of the upper chamber, in a downward direction to the lower chamber and out the drain.
