Abstract
A device is provided for distribution of 2-13% cellulose pulp to a movable processing surface in a pulp processing device to form a pulp web thereon. An inlet box has an inlet and an outlet defined therein. A rotatable distribution means is arranged for distributing pulp along an entire length of the outlet. The distribution means is placed so that a first distance (a1) between the distribution means and a first outlet wall is greater than a second distance (a2) between the distribution means and a movable processing surface.
Claims9
A device for distribution of cellulose pulp having a concentration of 2-13% to a movable processing surface in a pulp processing device to form a pulp web on the processing surface, the pulp web being transported together with the processing surface in a first direction (D1), comprising:
- an inlet box having an inlet (5) defined therein for incoming cellulose pulp to the inlet box, an outlet for transferring the cellulose pulp to the pulp web, the outlet facing the pulp web the outlet having a length (L) corresponding to a width of the pulp web, the outlet having a width delimited by a first long wall and a second opposed long wall, the second long wall being essentially parallel to the first long wall;
- a rotatable distribution means for distributing the cellulose pulp along essentially the entire length (L) of the outlet, the rotatable distribution means being arranged between the first long wall and the second long wall;
- the rotatable distribution means being placed so that a first distance (a1) between the distribution means and the first long wall is greater than a second distance (a2) between the distribution means and the processing surface.
A method for distributing cellulose pulp having a concentration of 2-13% to a pulp web on a movable processing surface in a pulp processing device, comprising:
- moving the processing surface in a first direction (D1),
- feeding cellulose pulp to an inlet box having an outlet defined therein facing the pulp web,
- providing the inlet box with a length (L) corresponding essentially to an entire width of the processing surface, providing a distribution means disposed at a distance (a1) from a first outlet wall, the distance (a1) being greater than a second distance (a2) extending between the distribution means and the processing surface,
- the distribution means distributing the cellulose pulp along essentially an entire width of the pulp web (2),
- the distribution means allowing the cellulose pulp to pass essentially unimpededly through the outlet to the pulp web.
