METHOD OF MIXING COMPONENTS OF PAPER PULP DURING PROCESSING OF WASTE PAPER AND MIXING UNIT FOR ITS IMPLEMENTATION Russian patent published in 2024 - IPC D21B1/08 D21B1/34 B01F27/00 D21D5/00 

FIELD: processing of waste paper.

SUBSTANCE: group of inventions relates to processing of waste paper, namely to a method of mixing components of paper pulp when processing waste paper material and to a mixing unit for its implementation. Unit for mixing components of paper pulp during processing of waste paper material consists of a massive two-chamber mixing basin, into which a manifold and an intake branch pipe of the pump are embedded, wherein in each of the chambers a mixing device is supplied, made with possibility of being driven by an electric motor through a drive belt and a reduction gear or a conical gear reducer, directly connected to the rotor shaft, the intake branch pipe is connected to the headbox through the pump and supplies, at that, the manifold branch pipe and the pump intake branch pipe are embedded into the mass basin at angle of 45° in different directions, and each of them is installed on different sides of the partition, which is installed in the centre of the pool parallel to the walls of the chambers for a length extending beyond those edges of the chambers, into which the mixing devices are connected.

EFFECT: reduced risk of manifold clogging, increased time and intensity of primary mixing of flows, provision of stabilized direction of circulation of mass flow, avoiding risk of incompletely homogenised mass flow entering into headbox.
