Abstract
A device for washing and dewatering a fiber pulp suspension. The device has two hollow, circular-cylindrical screen members that contain evacuation chambers for conducting away liquid. The screen members rotate towards each other for the purpose of forming a nip. At least one of the screen members is arranged in a trough which partially encloses the casing and which converges towards the casing in the direction of rotation of the screen member. At least one pulp inlet box is arranged at the highest point of the screen members for the purpose of introducing pulp between the casing the trough. The pulp inlet box is provided with a pressure equalization section in which a certain equalization of irregularities in pulp qualities takes place before the pulp is fed into the actual washing or dewatering gap.
