Abstract
The invention relates to a filter belt press for separating solid matter from material suspensions, in particular fibrous material suspensions, in which the filter belts are guided through a wedge-shaped dehydrating zone in which the filter belts are supported at least over portions by wedge-like converging filter plates. For an optimation of the pressing effect, it is provided that the filter belts (3,4) be guided from this first dehydrating zone (1), in which the filter plates (5) are optionally supported by dehydrating boxes (6) or provided with dehydrating boxes (6) on their outsides, into a surface press (2) or surface pressure means for the material (29) or filter cake present between the filter belts (3,4), the press (2) in particular being immediately adjacent the end of the wedge-shaped dehydrating zone (1).
