Abstract
A device for feeding cellulose-containing pulp from a dewatering unit, the dewatered pulp being discharged via an outlet included in the dewatering unit to a reception means positioned below the outlet, whereupon the pulp is transported to a stand pipe via an inlet included in the stand pipe, in which stand pipe the pulp falls freely under the influence of gravity, the reception means being positioned at a higher level than the inlet of the stand pipe. At least one feeding down surface is arranged which extends from the reception means to the inlet of the stand pipe, and the transport of the pulp between the reception means and the inlet of the stand pipe is effected by feeding the pulp downwards along this feeding down surface under the influence of gravity, the pulp being diluted during the feeding of the pulp downwards.
