A froth flotation apparatus for elimination of solid particle impurities contained within a liquid includes a vessel defining a flotation cell which includes an upstanding foam discharge conduit, an inlet conduit communicating with the vessel such that fluid flowing through the inlet conduit and into the vessel moves in a vortical fashion within the vessel, a skimmer, and a sparger. The skimmer consists of a generally cylindrical roller which is rotatably mounted between the discharge conduit and a side wall of the vessel and is buoyant so that it floats on the surface of the fluid within the vessel such that it is rotated by the vortical movement of the fluid within the vessel to prevent buildup of foam and maintain the motion of the fluid within the vessel. The sparger includes a substantially cylindrical porous element mounted on a tubular shaft which is rotatably mounted within the inlet conduit and driven by a motor. Compressed air is forced through the porous element to aerate the fluid entering the vessel. Two or more flotation cells may be arranged in a tower to provide series operation in which the liquid effluent of one cell flows downwardly by gravity into a subsequent cell, thereby eliminating the need for additional mechanical pumps.
191 Apparatus for selective floatation of substance JP516583 1983-01-14 JPS58180250A 1983-10-21 RICHIYAADO BAKUSUTAA UEBAA; ROBAATO HENRII FUOOSAISU
A flotation machine consists of a flotation chamber and a rotating gas diffuser. The flotation chamber has a lower mixing chamber and an upper quiescent zone for maximizing float accumulation. The rotating diffuser produces ultra fine bubbles as small as 50 microns in diameter. The size of the bubble diameter can be controlled and produced in any size from less than 50 microns to greater than 10 mm to enable flotation of various materials and/or various sized fractions of materials. The ultra fine bubbles are produced by the diffuser in the same size range as bubbles produced by dissolved air flotation, but without the necessity of pressurizing gas in a first tank followed by depressurizing in a second tank. Since the diffuser is located within the flotation chamber and can vary bubble size, it also provides the advantage of sparged air flotation. This rotating diffuser configuration is a low drag thin disc and, when combined with a specially designed flotation chamber, embodies a flotation machine which produces higher product yields over a wider range of feed size fractions utilizing significantly less energy.

Apparatus for de-inking waste paper pulp using a foam flotation process in which the deinked slurry is to be recycled for the production of paper. The old paper is pulped (slushed), mixed with water and flotation- and other chemicals, to produce a slurry which is introduced into the flotation tank. Movement of the slurry through the flotation tank is achieved by the positioning of one or more water injector nozzles with air inlets which causes a swirling rotation from the injector towards a central outlet. Froth or foam bubbles float to the surface of the slurry carrying ink particles. A baffle plate leads the floated froth or foam and ink particles to a vacuum actuated outlet.
