ROTARY PULSATING MACHINE Russian patent published in 2014 - IPC B01F7/02 

FIELD: engines and pumps.

SUBSTANCE: proposed machine relates to dispersion, homogenising and transfer of homogeneous mixes. It comprises rotor (1) and stator (2) arranged in case (3). Rotor (1) and stator (2) working surfaces are equipped with ribs (4, 5) arranged in rows in circle to alternate with grooves (6, 7). Note here that rotor (1) is fitted on drive shaft (8) for reversible turn thereon. Inlet vanes (12) are arranged at rotor (1) working surface while extra inlet vanes (13) are arranged between said inlet vanes (12). Note here that ribs (4) of the last row make the outlet vanes (14) and feature different shape in length and cross-section for various versions. Quantity of extra vanes (13) equals or exceeds that of inlet vanes (12). Vanes (12, 13, 14) feature (for rotor reversible rotation) angle of attack α and exit angle β equal on both sides but different shape over the length and cross-section for various versions. Mirror axes of said blades 12, those of extra inlet blades 13 and of outlet of blades 14 are located radially while pressure pipe lengthwise axis (15) and central axes of rotor (1) and stator (2) are located on one straight line.

EFFECT: longer life.
