Flotation machine rotor

摘要

A rotor for flotation machines or flotation cells of flotation machines includes blades that are configured to provide improved bubble flow and bubble generation performance while also reducing the power requirements for rotating the rotor to generate bubble flow within a tank of a flotation cell used to generate froth. Embodiments of the rotor may also be configured to be smaller than conventional rotor designs, which may help reduce the costs of manufacturing the rotor or flotation machines using such embodiments of the rotor.

主权项

1. A flotation machine comprising:
at least one flotation cell, each of the at least one flotation cell comprising:
a tank that is sized to retain a slurry comprised of a liquid mixed with at least one solid material;a rotor positioned in the tank, the rotor rotated to agitate the slurry to facilitate formation of bubbles, the rotor comprising:
a body having an inner channel and a lower opening;
a plurality of inner blades attached to the body, the inner blades being positioned inside the body adjacent the inner channel, the inner blades at least partially defining a plurality of conduits within the body, the conduits being in communication with the inner channel, each of the conduits being defined within the body to extend from an inlet interfacing with the inner channel within the body to an outlet on an external surface of the body so that slurry pulled into the lower opening via rotation of the rotor passes through the inner channel and is ejected from the external surface of the body via the conduits at locations positioned above the lower opening; anda plurality of outer blades attached to the body such that the outer blades rotate when the body is rotated, the outer blades being positioned above the lower opening, the outer blades extending outwardly from the external surface of the body away from the outlets of the conduits; and wherein the body also has passageways separated from the conduits, each of the passageways having an inlet to receive at least one gas and an outlet to emit the at least one gas received via the inlet, the outlet of each passageway being spaced apart from the outlets of other passageways, the outlet of each passageway being positioned in the body between immediately adjacent outer blades.
