<p>The present invention relates to a washing apparatus for washing of cellulose pulp comprising: a rotatable drum ( 2 ), a stationary support ( 14 ), a stationary cylindrical casing ( 18 ), that encloses the drum, whereby an annular space ( 20 ) is defined between the casing and the drum, a number of seals ( 22 ) that are arranged on the casing and that seals between the casing and the drum, such that the annular space is divided in a formation zone (F), at least one washing zone (T 1 , T 2 ), and a discharge zone (U), and at least a reinforcing frame rib ( 24 ), that is attached to the casing. The reinforcing frame rib ( 24 ) extends around the entire casing ( 18 ) for fixing the casing in a predetermined form, whereby detrimental deformation of the casing ( 18 ), when washing the paper pulp at overpressure, is prevented.</p> |
