ABSTRACT:
A dewatering device with two filtering belts comprising two endless bands guided over drums and a gap limited by the bands for a heap of debris as pressure product guided through this pressure zone, with a supporting means being allocated to one of the bands on that side looking away from the heap of debris is to be improved concerning its dewatering activity. For this purpose, the supporting means is provided in the form of a supporting plate (20) curved in the driving direction (x), which supports a sieve-like belt or band (13) in the pressure zone and shows break-throughs. The band (13) rests on a gliding plane of the curved and perforated supporting plate (20), the radius of curvature (r) of which decreases towards the driving direction (x). The supporting plate (20) is composed of a flexible material so that its radius of curvature (r) can be adjusted.
