Mixer for mixing two fluids, producing a constant volume flow, for feeding the headbox of a paper machine

摘要

The invention relates to a mixing device for mixing two liquids at the feed to the headbox of a paper machine, comprising: a feed line (A) for the first partial volume flow (a); a feed line (B) for the second partial volume flow (b); a derivative (C) for the mixture volume flow (c) with the flow resistance (W); a mixing angle (A) with the feed line (A) and the feed line (B); a main flow angle (β) between the inlet (A) and the outlet (C); an actuator (S) installed in the supply line (B) to regulate the partial volume flow (b). The invention is characterized in that the mixing angle (A) is selected such that the mixture volume flow (c) remains constant regardless of the partial volume flow (b). IMAGE
