A device for cleaning a filter cloth (4) of at least one filter element (3) in a rotary disc filter (1), including at least one flush tube (6), the centre axis of which is located between two adjacent parallel filter elements, and which includes at least one outlet (9) arranged in a direction other than towards the respective filter cloth (4), and at least one spray nozzle (5) connected to said outlet (9). A connection (13) to the spray nozzle (5) extends essentially parallel to said filter element (3) and the spray nozzle (5) includes an angled redirecting channel (14) for distribution of cleaning liquid in a direction towards the filter cloth (4) of said filter element (3). A plurality of spray nozzles (5) are arranged in pairs around the flush tube (6) and with their respective outlet openings (8) located at a distance from the respective filter element (3), which is larger than half the spacing between two adjacent parallel filter elements (3). |
