A cleaning device is moved in conjunction with the rotary shaft and includes upper and lower flushing cocks communicating with an outflow valve via the shaft for cleaning the candles during a backflushing operation. The upper flushing cockis offset by an angle in the direction of rotation in relation to the lower flushing cockA lower closure elementmoves in conjunction with the upper flushing cock at the opposite end of a filter candle(s) selected for backflushing. Likewise, an upper closure element is associated with the lower flushing cock.
