Abstract
A dewatering drum for dewatering of cellulose pulp has two end plates, which are arranged at either end of the dewatering drum. The dewatering drum further has a support pipe, which has the shape of a cylindrical sleeve having a material thickness of at least 15 mm, and which, at its respective ends, is connected to the end plates. A liquid-permeable layer is arranged on the outside of the support pipe and is held in position at a distance from the outer periphery of the support pipe by means of spacer elements. The support pipe is provided along its periphery with at least ten openings through which liquid that passes through the liquid-permeable layer is able to penetrate into the interior of the support pipe.
