PCT No. PCT/SE87/00263 Sec. 371 Date Oct. 28, 1988 Sec. 102(e) Date Oct. 28, 1988 PCT Filed May 27, 1987 PCT Pub. No. WO87/07662 PCT Pub. Date Dec. 17, 1987.An apparatus for treating fibre material containing liquid, comprising two rotating drums (2, 3), an endless driven belt (17) pervious to liquid and gas and extending between and passing around the surfaces (8, 9) of the drums, a feeding device (10) for the supply and a discharging device (13) for the removal of the fibre material, at least one container for collecting liquid, the liquid being displaced from the fibre material through the endless driven belt (17), a continuous wall (18) impervious to liquid and gas and extending along a main part of and at a distance from the belt (17) from the feeding device (10) to the discharging device (13) in such a manenr that a continuous space (19) is defined for the fibre material between said wall (18) and the belt (17), and at least a part of the space (19), seen in the direction of movement of the belt (17), forms one or more treating zones where liquid is displaced from the fibre web through the movable belt (17) to one or more containers. According to the present invention the distance between belt (17) and wall (18) is about 5-100 mm, preferably about 10-50 mm, and is chosen depending primarily on the fibre concentration of the fibre material so that the fibre material is moved by the moving belt (17) in the form of a fibre web substantially continuous in all directions through said space (19) in sliding contact with the wall (18) with substantially no relative movement between the belt (17) and fibre web or layer thereof. |
