Abstract
The housing (2, 3, 4) of the filtering device has a cover (4), provided with a filtrate outlet (9), a cover that is detachable applied to a housing part (3) exhibiting an intake (7) for the suspension (8) to be filtered. A filter (11) is placed between housing part (3) and cover (4). A rotor (14), provided with stripping lamellae (17) for stripping the solids settling on the filter (11), rotates in the housing (2, 3). The filter (11) is formed by a flat, plane screen (11) placed perpendicular to the axis of a rotor (22). The intake (7) is aligned radially to the lamellae (17). For replacing or cleaning the filter (11), it suffices to remove the housing cover (4). The lamellae (17) are cleaned by the suspension flowing in the filtering device.
