<p><P>PROBLEM TO BE SOLVED: To extended a maintenance period while enhancing the persistence of the filtering capacity of a water cleaning device and making it easy to clean a filtering layer. <P>SOLUTION: In the automatic water cleaning device 1 cleaning dirty water by making pass through the filtering layer 10 installed in a cleaning vessel 2 by a circulation pump 4, a water sucking opening 11a connected to the circulation pump 4 is provided above the filtering layer 10, flowing-in openings 9, 9, 9, 9 of the dirty water are arranged below the filtering layer 10, and a sludge precipitation part 7 making sludge precipitate is provided below the filtering layer 10. The dirty water is filtrated by making the dirty water pass through from below the filtering layer 10 to the upper part by sucking the dirty water from the water sucking opening 11a by using the circulation pump 4 and the sludge generated by filtering the dirty water is allowed to precipitate into the sludge precipitation part 7. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
