HYDROPERCUSSION ROTARY APPARATUS Russian patent published in 1998 - IPC

FIELD: material mixing and grinding; may be used in processes of dispersion of homogeneous and heterogeneous suspensions with use of hydraulic shocks. SUBSTANCE: apparatus has body in the form of volute chamber with inlet and outlet pipes. Installed inside body are concentrically arranged working members, rotor and stator with slots in their side walls. Rotor is separated into two parts - internal and external by ring-shaped depression. Located on rotor internal part are blades producing centrifugal force and imparting initial speed to treated flow. Rotor external part has on its side walls slots in the form of widening hollows with concave surfaces. Located in ring-shaped depression of rotor is stator whose side walls have slots in the form of subsonic nozzle. Stator slots are oriented along axial curved lines constructed by parabolic law. EFFECT: intensified process of dispersion, higher efficiency of apparatus and prolonged service life of its working members. 2 cl, 3 dwg
