MIXING AND KNEADING DEVICE Russian patent published in 2000 - IPC

FIELD: mechanical engineering. SUBSTANCE: device has at least two rotating shafts with parallel axes. Each shaft carries at least two kneading and transfer members following each other in direction of shaft rotation. Space is formed between kneading and transfer members of each shaft following each other in axial direction. Parts of kneading and transfer members of other shaft pass through this space. Kneading and transfer members of each shaft following each other in direction of shaft rotation are shifted partially along axis. Number of kneading and transfer members, rotational speed and direction of shaft rotation are correlated so that kneading and transfer members of identical axial shift interact. Each of kneading and transfer members consists of radial carrying element and kneading blade set on it. Radial carrying member is coupled to ring which is part of shaft and made integral with it. Pairs of shaft rings are separated from each other by tubular sections. EFFECT: improved quality of surface cleaning process. 2 cl, 7 dwg
