MIXING SYSTEM FOR MIXING TWO LIQUIDS AT CONSTANT MIXTURE VOLUME FLOW FOR SUPPLYING THE HEADBOX OF A PAPER MACHINE

摘要

The invention concerns a mixing system for mixing two liquids at the inlet to the headbox of a paper machine with: an inlet line for the first partial volume flow ; an inlet line for the second partial volume flow ; an outlet line for the mixture volume flow with the flow resistance ; a mixing angle with the inlet line and the inlet line ; a main flow angle between the inlet line and outline line ; an actuator installed in the inlet line for control of the partial volume flow. The mixing angle is selected so that the mixture volume flow remains constant, independent of the partial volume flow.
