DEVICE FOR SEPARATING SUSPENSIONS Russian patent published in 1994 - IPC

FIELD: separating materials. SUBSTANCE: device has a case provided with charging branch pipe 2 inclined to face part of case 1. Perforated drum is received within the case. Rotor- pulsating unit is secured to shaft 4 within the drum. The unit has stator 5 and rotor 6, double entering screw 7 provided with blades 8 secured between its turns, and rotor 9 made of two ring disks 10 coupled via three-eight horizontal blades 11 inclined to axis of rotation of shaft 4 by 10-20°. Width of each blade 11 is equal to 0.3-0.4 of diameter of rotor 9. Faces of blades 11 are cut at an angle 10-30° to axis of rotation of shaft 4. One of the faces of cut plane of blade 11 points from bottom edge to charging branch pipe 2 and the other one to discharging branch pipe 13. EFFECT: enhanced efficiency. 2 dwg
