Abstract: The method and a device is for the dilution of dewatered cellulose pulp that maintains a consistency of 20-30% or greater. By shredding of the pulp to a finely divided dry-granulate, dilution to a homogeneous consistency in the medium consistency range can take place exclusively through hydrodynamic effects from the addition of dilution fluid. The dilution fluid is added to granulate at a position at which granulate is in free fall in a standpipe and above a level Liq.sub.LEV of diluted pulp in the standpipe. A number of nozzles are arranged around the periphery of the stand pipe, directed in towards the centre of the stand pipe, obliquely downwards in the direction of fall of the granulate. It is possible through this simplified procedure to avoid completely the conventional dilution screws, and this reduces the investment costs and operating costs, while at the same time unnecessary mechanical influence of the pulp fibres can be avoided.

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.

Abstract: The invention presents a pulp concentration adjusting method and its device for realizing a used paper recycling apparatus being installed in a room of a small shop or the like, friendly to the environment, low in running cost, and capable of maintaining a high confidentiality. The pulp concentration adjusting section is characterized by dividing a specified portion from the whole volume of used paper pulp manufactured in pulp making section in preceding process, adding water for adjusting concentration to the divided portion of used paper pulp, and adjusting the total volume of the divided portion of used paper pulp and water to a specified value, thereby preparing a pulp suspension of specified concentration. In this manner, by adjusting the concentration of used paper pulp in dividing portions (small portions), the water consumption can be saved substantially and the apparatus size is reduced, while enhancing the processing capacity.
