HYDROCYCLONE WITH FINE MATERIAL REDUCTION IN THE CYCLONE UNDERFLOW

摘要

The object of this invention is a hydrocyclone (1) with an inlet area (2) with a tangential inlet (4) for an object slurry (6) and another at the inflow region (2) adjoining the separation zone (3) with a Unterlaufaustragsrohr (8) for removal of heavy fabrics and Oberlaufdüse (9) which projects axially in the form of a dip tube in the interior of the hydrocyclone (1). In the region of the tangential inlet (4), a further inlet (5) for supplying a barrier fluid stream (7), wherein the barrier fluid (7) and the object slurry (6) in the hydrocyclone (1) before they are combined by a slat (10) are separated. According to the invention the separation zone (3) comprises a conical portion (15) and an adjoining cylindrical portion (18) above the Unterlaufaustragsrohres (8).
