| 摘要 |
The invention relates to a filter device designed for the insertion of filter elements ( 28 ), which can be positioned in a filter housing ( 10 ) comprising a filter inlet ( 20 ) and a filter outlet ( 22 ) for the fluid to be filtered, said filter elements ( 28 ) being traversed in both directions for filtration or backwashing. Certain filter elements ( 28 ) perform the filtration in a filtration position and at least one additional filter element ( 28 ) can be backwashed in a backwashing position to clean its active filtration surface. As the individual filter elements ( 28 ) are brought into the backwashing position and are then returned to their filtration position in succession by means of a pivoting device ( 30 ), the filter elements are individually displaced into the backwashing position in a temporal sequence, in contrast to prior art, where an arm-type backwashing device is pivoted towards the individual filter elements in order to carry out the backwashing process.
