    Abstract: A composite hollow aspirator shaft is formed of fiberglass-reinforced phenolic resin that resists abrasion and reduces the amount of vibration that is transferred to the motor rotating the shaft, and the motor's bearings to extend motor and bearing life. An aspirator tip is adhesively attached to the composite aspirator shaft and includes an access hole for cleaning inside the hollow aspirator shaft. The hole is in axial alignment with the hollow aspirator shaft and a selectively-removable plug is used to seal the hole during aspirator use. When the aspirator tip is rotated in a liquid, fluidic forces are transferred to the shaft where they are attenuated. A splined hub is used to attach a foam restrictor near the other end of the shaft. The composite shaft material has a flexural modulus, or ratio, within the elastic limit of any applied stress.

This extends motor and bearing life. When the aspirator tip is rotated in a liquid, fluidic forces are transferred to the shaft. Rather than transmitting those forces into the motor and its bearings, the composite aspirator shaft attenuates the forces to prevent most of them from reaching the motor and its bearings. The composite shaft material has a flexural modulus, or ratio, within the elastic limit of any applied stress, and is sufficiently low to allow the transfer of the flexural or oscillatory energy into heat within the shaft instead of conveying the energy in the form of vibration/oscillations along the axial length of the shaft. As an added advantage, the fiberglass resists abrasion better in wastewater than stainless steel used in the prior art.

    Abstract: A multi-direction submersible floating aerator has a gas-ring compressor (4), a base (6), a gas inlet tube (9), a seat (11), multiple submersible hollow shaft motors (13), and multiple propellers (14). The base (6) is disposed between the gas-ring compressor (4) and the gas inlet tube (9). The propeller (14) is coaxially connected to the submersible hollow shaft motor (13). The seat (11) is disposed between the gas inlet tube (9) and the submersible hollow shaft motor (13). The seat (11) is hollow. A first opening is disposed at the top of the seat (11), and multiple second openings are disposed on one side of the seat (11). The seat (11) is used for evenly distributing compressed air.

    Abstract: The invention provides an agitator (1) is disposed to agitate slurry within a flotation tank (2). The agitator includes a rotor (6) mounted on one end of a centrally disposed drive shaft (7) extending axially downwardly into the tank and driven by a motor (8) and associated gearbox (not shown). The other end of the drive shaft includes a mounting flange (9) adapted for connection to the motor. A stator (10) is also provided around the rotor. A froth deflection cone (11) extends around the drive shaft adjacent the top of the tank. The deflection cone is oriented such that its smallest diameter is located at its lower-most end nearest the rotor (6). An auxiliary agitator (12) is connected to the drive shaft at a position substantially midway between the underside of the deflection cone (11) and the top of the rotor (6), as shown in FIG. 1 and FIG. 2. The auxiliary agitator (12) includes agitation blades (13) extending radially outwardly from diametrically opposite sides of the shaft (7).

  • Publication number: 20100258509
    Abstract: There is provided a microbubble generating method including: supplying a gas to a rotator 2 while rotating the rotator 2 in a liquid; injecting the gas into the liquid from bubble injection holes formed in the surface of the rotator 2; and applying a shear force, produced by the relative movement between the liquid and the rotator, to gas bubbles present on and in the vicinity of the surface of the rotator 2 to generate microbubbles. The microbubble generating method can easily generate a large amount of microbubbles without forcibly creating a swirling flow of fluid.

  • Publication number: 20090243124
    Abstract: A composite hollow aspirator shaft is formed of fiberglass-reinforced phenolic resin that resists abrasion and reduces the amount of vibration that is transferred to the motor rotating the shaft, and the motor's bearings to extend motor and bearing life. An aspirator tip is adhesively attached to the composite aspirator shaft and includes an access hole for cleaning inside the hollow aspirator shaft. The hole is in axial alignment with the hollow aspirator shaft and a selectively-removable plug is used to seal the hole during aspirator use. When the aspirator tip is rotated in a liquid, fluidic forces are transferred to the shaft where they are attenuated. A splined hub is used to attach a foam restrictor near the other end of the shaft. The composite shaft material has a flexural modulus, or ratio, within the elastic limit of any applied stress.
