MIXER BLADE SHAFT Russian patent published in 2006 - IPC B28C5/14 B01F7/04 

FIELD: apparatuses for preparing mixtures containing solid and liquid components.

SUBSTANCE: blade shaft is hollow and it includes blades in the form of plates of strength dense material secured to struts mounted on shaft. Each strut has opening along is lengthwise axis communicated with cavity of shaft and it is mounted with possibility of rotation and fixation of predetermined position. Blades are secured to struts in such a way that they do not close openings of strut. Plate of each blade is closed with gap at working side by means of lining of material permeable for gas and liquid. Gap between plate and lining is sealed along perimeter. Inner cavity formed by sealing gap is communicated through openings of strut and cavity of shaft with source of pressurized liquid or gas.

EFFECT: lowered power consumption, decreased resistance coefficient at mixing, intensified process of mixing, increased useful life period of blades.
