    Abstract: An aerator (10) is disclosed which includes a hollow outer tube (12) and a hollow inner tube (14) rotatably supported therein. The inner tube is drivingly connected to a drive shaft (28) of the motor (18). A mounting flange (34) extends from a first end (36) of the outer tube and a mounting bracket (30) is interposed between the mounting flange and the motor. The mounting bracket and mounting flange are removably attached to the motor. A bearing mechanism which includes a bearing (44) and a ceramic wear sleeve (46) rotatably support a second end (40) of the inner tube adjacent the second end (42) of the outer tube. A propeller (20) is attached to the second end of the inner tube and has a pitch which is sufficiently high to move liquid past it at a velocity wherein cavitation of the liquid above the propeller is prevented at a preselected operating rotational speed.

    Abstract: An apparatus (10, 212) for mixing a gas and a liquid is disclosed. The apparatus is comprised of a hollow outer housing (22) and a hollow inner tube (24) received for rotary motion within the outer housing (22). A motor (61) is attached to the outer housing (22) adjacent a first end thereof and is drivingly coupled to a first end of the inner tube (24). The inner tube (24) has a support tube (214) which extends beyond the second end of the outer housing (22). Propeller blades (216) are attached to the support tube (214) for rotation therewith. An inlet (82) is formed in the inner tube (24) for admitting a gas to the hollow interior of the inner tube (24). The support tube (214) has a diffusion section (222) that extends below the propeller blades (216). The propeller mechanism (210), which includes the support tube (214) and the blades (216), is designed to increase the oxygen transfer efficiency of the apparatus (10, 212) over that provided by a standard marine propeller (48). Each propeller blade (216) has an impelling surface (232) with a varying rake which changes to a more positive rake from a leading end (226) to a tail end (228) of each propeller blade (216). Plates (238, 240, 242) are attached to the air outlet end (224) of the support tube (214). Lower portions (250) of the plates (240, 242) are bent backward in the direction in which the propeller mechanism (210) is to be rotated.

    Abstract: A rotor for use in a slurry separation flotation cell having a tank within which the rotor is contained. The rotor has a shaft that has a conduit adapted to communicate a fluid, preferably a gas such as air, therethrough. The rotor also has impeller blades extending radially from the shaft and a baffle adjacent the bottom of the impeller blades. The baffle extends from an end of the shaft to at or near an outer edge of the impeller blades, directing the gas to the outer edges of the impeller blades for dispersion into the slurry. The rotor is located adjacent a floor of the tank and, in use, draws slurry downwards into the impeller portion and forces it outwards with the gas being mixed therein.

    Abstract: In a rotatable tube having an open end and a closed end, an aperture is disposed along a length of the tube and is associated with a blade configured to create a reduced pressure pocket within a fluid medium near the aperture. When the tube, the aperture and the blade rotate within the fluid medium, an input gas is drawn through the open end of the tube and into the fluid medium through the aperture.
