Abstract
A mixer for mixing and blending fluids within a vessel includes a passageway through which fluid is dispensed within the vessel and a flow diverter spaced from the passageway. Fluid impinges on the flow diverter and is directed toward the walls of the vessel. The diverter includes holes that produce jets of fluid generally parallel to the walls of the vessel to induce shear and turbulence within the fluid in the vessel.

A mixer for mixing fluids in a tank, said mixer comprising a body having a supply passage extending through said body to convey fluids and to discharge fluid through a discharge port located at one end of said supply passage, said mixer including a flow diverter spaced from said discharge port to be impinged by a fluid flowing through said port, said flow diverter including an impingement surface directed toward said supply passage and extending laterally beyond said supply passage to direct fluid radially relative to said supply passage, said flow diverter being slidably mounted in said body to permit relative movement between said impingement surface and said discharge port and having an abutment to limit movement of said flow diverter away from said, body, said flow diverter having at least one aperture extending from said impingement surface through said flow diverter to provide a jet of said fluid flowing through said discharge port generally parallel to the direction of fluid flow in said supply passage.
A mixer for mixing fluids in a tank, said mixer comprising a body having a supply passage extending through said body to convey fluids and to discharge fluid through a discharge port located at one end of said supply passage, said mixer including a flow diverter spaced from said discharge port to be impinged by a fluid flowing through said port, said flow diverter including an impingement surface directed toward said supply passage and extending laterally beyond said supply passage to direct fluid radially relative to said supply passage, said flow diverter being movably mounted in said body to permit relative movement between said impingement surface and said discharge port, said flow diverter having at least one aperture extending from said impingement surface through said flow diverter to provide a jet of said fluid flowing through said discharge port generally parallel to the direction of fluid flow in said supply passage, wherein said impingement surface is concave and wherein a frustoconical seat projects from said impingement surface at the center of said flow diverter.
A mixing system for mixing fluids comprising a tank having an external wall with a supply duct to supply fluid to said tank, said tank having a longitudinal axis a mixer located in said tank and having a passage communicating with said supply duct and terminating in a discharge port to discharge fluid into said tank, and a fluid outlet to remove fluid from said tank, said mixer including a flow diverter mounted for movement relative to said discharge port to be impinged by fluid flowing through said port, said flow diverter including an impingement surface directed toward said passage, said impingement surface extending laterally beyond said passage to direct fluid generally radially from said discharge port and being movable between a first position in which said impingement surface is spaced from said discharge port to a second position in which said impingement surface engages said discharge port, at least one aperture extending from said impingement surface through said flow diverter to generate a jet of fluid along said tank in a direction generally parallel to said longitudinal axis of said tank.
