Mixer for mixing two fluids, producing a constant volume flow, for feeding 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 (A) for the first partial volume flow (a); an inlet line (B) for the second partial volume flow (b); an outlet line (C) for the mixture volume flow (c) with the flow resistance (W); a mixing angle ( alpha ) with the inlet line (A) and the inlet line (B); a main flow angle ( beta ) between the inlet line (A) and outlet line (C); a valve (S) installed in the inlet line (B) for control of the partial volume flow (b). The mixing angle ( alpha ) is selected so that the mixture volume flow (c) remains constant, independent of the partial volume flow (b).
