Abstract
The present invention relates to a washing apparatus (2) for washing of cellulose pulp, comprising a rotatable drum (4), a stationary support (6), a discharge device (8) that has an outlet orifice (9), a casing that surround the drum and that forms a longitudinal discharge opening (10) and a conveyer worm (12) arranged below the outlet orifice for reception and removal of washed pulp. The conveyer worm (12) is movably arranged relatively the support (6) between a first position (P1), in which the conveyer worm receives washed pulp during operation, and a second position (P2), in which the outlet orifice (9) is exposed and access to the drum (4) via the outlet orifice is possible for carrying out service, maintenance and inspection of the washing apparatus (2).
