Devices for dewatering pulp suspensions can be complex and costly. The disclosed device provides a shorter and more simplified design. More specifically, disclosed is a device for dewatering a pulp suspension, wherein the suspension is dewatered between an upper belt and a lower belt, wherein a dewatering zone comprises a wedge-shaped zone formed by the upper belt and lower belt having an inlet end and an outlet end, and wherein a single, upper deflection roll and/or a single lower deflection roll are provided at the inlet end of the wedge-shaped zone.

L'invention concerne un procédé pour déshydrater des suspensions à base de solides et de liquides, notamment des suspensions à base de fibres. La suspension est déshydratée entre deux bandes (4, 5), une zone de déshydratation se présentant sous forme de zone cunéiforme. L'invention se caractérise principalement en ce qu'au début de la partie cunéiforme, les rouleaux supérieurs et/ou inférieurs se présentent sous forme de rouleaux de serrage.
