Boundary layer drum mixer

A boundary layer drum mixer comprising:

• a rotating motor;
• and
• a rotor assembly comprising:
• a shaft coupler;
• and
• a shaft;
• and
• an upper impeller;
• and
• a lower impeller;
• and
• a stator assembly comprising:
• a tubular housing;
• and
• an upper stator vane array;
• and
• a lower stator vane array;
• and
• an inlet stator vane array;
• and
• a media introduction port;
• and
• an array of inlet ports;
• and
• an array of outlet ports;
• and
• a lower radial friction bearing;
• and
• an adjacent vessel comprising:
• a rigid enclosure with sealed sides and bottom;
• and
• an affixed or removable lid;
• and
• an access port through the top of the vessel or lid;
• and
• a liquid-based media;
• wherein the rotating motor imparts rotational motion and energy to the rotor assembly, inducing liquid-based media from the adjacent vessel to be drawn into the media inlet ports, propelled through the impeller and stator arrangements, propelled through the tubular housing, propelled through the array of outlet ports and distributed throughout the liquid media in the adjacent vessel;
• wherein an upward flow of liquid-based media being propelled by the upper impeller and stator arrangement is delivered via the tubular housing to an array of upper outlet ports for distribution throughout the adjacent vessel for rapid and positive mixing and for entrainment of particles or liquid phases which tend to float at the top of the vessel.
