Abstract

Die Erfindung betrifft einen Turbulenzerzeuger (1) für einen Stoffauflauf einer Maschine zur Herstellung einer Faserstoffbahn, insbesondere einer Papier-, Karton- oder Tissuebahn, aus mindestens einer Faserstoffsuspension (2), mit einer Vielzahl von Turbulenzrohren (3) zur Führung und Verteilung der mindestens einen Faserstoffsuspension (2), wobei wenigstens ein Turbulenzrohr (3) im Strömungsverlauf der mindestens einen Faserstoffsuspension (2) sich mindestens einmal von einem ersten Querschnitt (A1) auf einen zweiten Querschnitt (A2) verändert und zumindest eine als Stufensprung (7) ausgebildete Querschnittsveränderung (ΔA) durch einen, in dem Turbulenzrohr (3) angeordneten Einsatz (8) erzeugt wird, der eine Einsatzlänge (L8) und einen Einsatzaußendurchmesser (D8) aufweist.
Der erfindungsgemäße Turbulenzerzeuger (1) ist dadurch gekennzeichnet, dass der Einsatz (8) einen Schlankheitsgrad (T) im Bereich von 1:8 bis 1:50, vorzugsweise von 1:10 bis 1:30, aufweist, wobei der Schlankheitsgrad (T) das Verhältnis von Einsatzaußendurchmesser (D8) zu Einsatzlänge (L8) ist.
