摘要:
A sealing device intended for sealing between an axle journal (21, 22, 23, 24) and a bearing housing (30, 57, 31, 58) for the axle journal (21, 22, 23, 24). The sealing device allows that the axle journal (21, 22, 23, 24) can be angled in a plane in relation to the bearing housing and can also take up axial movement. The sealing device comprises a stator ring (40), which is carried by two guide pins (41), and the stator ring (40) can be angled in a plane in relation to the guide pins (41). The sealing device comprises also a sealing ring unit (47), which is intended for sealing between the stator ring (40) and axle journal (21, 22, 23, 24), a bellow means (56), which is intended for sealing between the bearing housing (30, 57, 31, 58) and stator ring (40), and at least one resilient element (48), which is intended to ensure that the stator ring (40) abuts the sealing ring unit (47). The bellows means (56) can be made of a material withstanding aggressive liquids.
摘要:
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 (Tl, T2), 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.

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 (Pl), 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).
摘要:
The present invention relates to a device for dewatering material suspensions. It comprises two cylindric rotary rolls (1) where at least one of the rolls (1) is liquid permeable. The rolls (1) form between themselves a nip (2), through which the material is intended to pass downward from above while being dewatered at the same time. The invention has the object to solve the problems of pressed-out liquid (filtrate) re-wetting the material. For the liquid permeable roll (1) below the nip (2) at least one abduction surface (20) extending along the entire roll (1) is located along which surface at least parts of the filtrate are intended to run. The filtrate is led into a gill (17), which extends along the entire length of the roll (1) and comprises a liquid inlet (18) and a return flow protection (19).
