Abstract

The filter discs (12, 13) of the filter device are provided on both sides of a filter chamber (34) which surrounds annularly or in the form of a spiral a discharge chamber (5) closed on the intake side. For periodic cleaning, a suction nozzle (14, 15) for solids particles filtered out is arranged on each filter disc (12, 13), which suction nozzle extends over the radial width of the filter disc (12, 13). During cleaning, a drive (20, 21) rotates the discharge chamber (5) with the filter chamber (34) attached to it, so that the filter discs move along the suction nozzles (14, 15). In the case of a spiral filter chamber (34), only one pair of suction nozzles (14, 15) is necessary in that these are displaced along a guide rod by the rotary motion of the filter chamber (34). The rotary motion of the filter chamber (34) in one direction brings one of the filter discs (12, 13) to abut with one of the suction nozzles (14, 15). The other is closed during this by an isolating valve (45). An outwardly tapering cross-sectional shape of the filter chamber (34) enables engagement of the suction nozzles (14, 15) in the case of a small pitch of the threaded shape of the filter chamber (34) or in the case of a close arrangement of a plurality of filter chambers axially adjacently arranged. Thus, no special drive is necessary for moving a suction nozzle over the filter surface and the filter device, in relation to its size, has a large filter surface area. <IMAGE>
