Abstract
An extension flow mixer especially for viscous liquids has a housing ( ) with an end inlet ( ) connectable to a pressurized source of the liquid, and an outlet ( ) at an opposite end of the housing ( ). A mandrel ( ) located in the cavity has protrusions ( ) with sloping side surface, the outer edges of which cooperate with the internal surface ( ) of the cavity to divide the cavity into a series of chambers separated by slits, such that liquid passes successively through all the chambers and slits in moving from the inlet ( ) to the outlet ( ). The slits have cross-sectional areas which decrease in the liquid flow direction. The mandrel ( ) sides have helical grooves ( ) forming passageways with the housing wall ( ) which allow liquid to be distributed evenly around the edges of the mandrel ( ) to the inlet end or upstream chamber. The mandrel ( ) may rotate to provide additional shear mixing.
