    摘要： 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.

    摘要： A flotator for use in benefication, coal dressing, wet refining and so forth, incorporating a surface flotation technic. The flotator has a funnel-shaped liquid cell having a bottom of an area smaller than that of the top opening. A bubbling device is constituted by an upper sleeve partly immersed in the liquid contained by the cell, a lower sleeve disposed coaxially with the upper sleeve and fully immersed in the liquid. The upper end of the lower sleeve is spaced by a predetermined distance from the lower end of the upper sleeve to form therebetween a spaced region located at a small depth from the liquid surface. The bubbling device further has a rotary blade unit constituted by upper and lower blades separated by a flat partition plate. The rotary blade unit is adapted to rotate around the common axis of the upper and lower sleeves, and has a thickness or axial height substantially equal to the aforementioned predetermined distance in the spaced region, and is located such that the flat partition plate is located at the heightwise mid point of the spaced region. The flotator further has a liquid surface stabilizer constituted by a frusto-conical member disposed around the bubbling device and adapted to deflect the liquid downwardly. Further, provided are a feeding passage having a feed gate opening in the bottom area of the cell and a discharging passage having a discharge gate spaced from both of the feed gate and the lower edge of the liquid surface stabilizer so as to avoid the "short-circuiting" of the liquid.

    摘要： PROBLEM TO BE SOLVED: To provide an improved-type reaction apparatus for purifying a fibrous suspension dispersed in a liquid, capable of being simply produced at a low cost, and to provide a purifying method. SOLUTION: This reaction apparatus (1, 30) for purifying the fibrous suspension dispersed in the liquid is equipped with an approximately cylindrical container (2), one or more blades (3) arranged in the container, a plurality of supply units (5 to 9) for supplying the inside of the container with the suspension to be purified together with a gaseous material which is dispersed in the suspension by being formed into a bubble shape, suspension-blocking means (14, 16) arranged in the container, and a means (10) for removing/discharging bubbles and the purified suspension. Each of the supply units (6 to 9) is equipped with at least one of supply pipe (6a to 9a) on which a plurality of injectors (6d to 9d) is mounted and which extends into the inside of the container, and further each of the injectors has a spraying direction (Z) facing an inner surface (2a) of the container, for the purpose of starting to supply the suspension to be purified from an inner portion of a cross section (S) of the container.

    摘要： An improved method and apparatus for froth flotation separation of the components of a slurry, having particular utility for the beneficiation of coal by the flotation separation of coal particles from impurities associated therewith, such as ash and sulfur. In this arrangement, a forward product stream is formed in which a mixture of the particulate matter slurry and the chemical reagents is sprayed through a nozzle at a first relatively low pressure onto the surface of water in a forward stream flotation tank to create a floating froth phase containing therein a first quantity of the particulate matter. The remainder of the particulate matter slurry separates from the froth phase by sinking in the water, and the froth phase is separated as a first product. The remainder of the particulate matter slurry is then directed to a scavenger product stream in which the separated slurry is sprayed through a second nozzle at a second higher pressure onto the surface of water in a second scavenger stream flotation tank to create a floating froth phase containing therein a second quantity of the particulate matter. The second froth phase is then separated as a second product. The amounts of the products recovered in the first and second product streams are substantially independently adjustable by controlling the first and second spraying pressures.

    摘要： 1396250 Purifying water by gas-stimulated flotation IMPROVED MACHINERY Inc 22 Nov 1973 [13 Dec 1972] 54164/73 Heading C1C Apparatus suitable for clarifying influent waters such as sewage and other slurries utilizing gas-stimulated flotation of the solid material in the influent water comprises a vessel with a vertical clarifying chamber (10); influent water supply means (52) for upwardly supplying water substantially above the lower end; gas supply means (54), arcuately spaced, which produces gaseous bubbles immediately adjacent to their discharge substantially below the influent water supply; solid discharge means (22) adjacent to the upper end of the clarifying chamber; liquid discharge means (28); the position of the clarifying chamber between the gas inlet and liquid inlet (56) being free of transversely extending separating media to permit the gaseous bubbles to rise readily and cause upward movement of solid material contained in the influent water while liquid influent is discharged downwardly. The apparatus and methods may also be employed for clarifying a mineral/liquid, fibre/ liquid, or other slurry where solids recovery is of paramount interest. Gases other than air may be used for effecting the flotation separation.
