    摘要： An impeller, a system for mixing a fluid, and a method of mixing a fluid in a tank are disclosed. For a sufficiently small impeller diameter and maximum blade tip velocity, the disclosed impeller, system, and method are capable of accelerating a near-zero intake velocity fluid, to generate a mixing zone that is collimated enough to have sufficient velocity vectors to suspend particles at a large distance away from the impeller, while minimizing the required power draw. An impeller may include a hub defining a longitudinal axis and plural blades spaced circumferentially about the hub. Each blade may include a root portion and a tip portion. Each blade may define a leading edge having an approximately circular raked helical geometry. A system for mixing a fluid may include a tank for containing the fluid, a drive shaft for extending into the tank, and the impeller.

    摘要： An impeller assembly includes a shaft, multiple scoops spaced circumferentially about the shaft, each scoop including an upper blade portion and a lower blade portion, spaced apart at the leading edges and joined at the inner edges, and a rib extending rearward from the inner edges, each scoop being coupled to the shaft by attachment at the rib. A system and method for mixing gas or liquid into liquid include a vessel for containing liquid, a drive shaft for extending into the vessel, and an impeller assembly adapted for rotating about the drive shaft, adapted for submerging below the liquid surface, and having multiple scoops, each scoop including an upper blade portion and a lower blade portion, spaced apart at the leading edges and joined at the inner edges, and a rib extending rearward from the inner edges, each scoop being coupled to the shaft by attachment at the rib.

    摘要： A method of mixing paper stock, having improved outlet consistency, includes: (a) feeding liquid and feeding paper pulp into a vessel to form a mixture; (b) providing at least one counterflow impeller that is submerged in the mixture, the counterflow impeller being capable of simultaneously inducing both upward flow and downward flow; (c) rotating the counterflow impeller such that downward flow from the impeller is partially recirculated by upward flow from the impeller to form a mixing zone; (d) sensing a parameter of the mixture discharged from the vessel; and (e) controlling the feed rate of the liquid and the feed rate of the paper pulp in the feeding step (a) based on the sensing step (d). An apparatus for mixing of paper stock, having improved outlet consistency, includes a vessel for containing liquid and paper pulp, at least one counterflow impeller, and a feedback system for controlling outlet consistency.
