摘要： 1,144,463. Froth flotation; agitating, aerating and circulating liquids. LICENCIA TALALMANYOKAT ERTEKESITO VALLALAT. 22 March, 1966 [28 Sept., 1965], No. 12665/66. Headings B1C and B2H. In a froth flotation apparatus, a homogeneous distribution of air and of a slurry of granular materials to be separated is achieved by pumping a mixture of the slurry and air into the flotation tanks via vortex forming chambers arranged in the tank in at least two separate groups, the whole of the slurry being fed to one group of the vortex forming chambers and the slurry being pumped out of the tank and re-circulated therein through anothre group of other groups of the vortex forming chambers. In Fig. 1, slurry is fed from a conditioning tank 1 by means of a pump 2 and distributing pipes 3 into a first group of vortex generators 5 arranged in the front part of the flotation tank 6. Each vortex generator, which may be made of cast basalt, rubber or synthetic material, consists of a double-walled vortex chamber 27, Fig. 4, with conduits 32 opening into the space between the inner and outer walls. A tangential inlet 23 to the vortex chamber has a built-in injector 24 in the inlet of which a conduit 26 opens. A conduit 25 opens on the axis of the chamber 27 below its discharge orifice 28. In operation, the slurry is fed through the inlet 23 and in passing through the injector 24 causes air to be sucked in through the conduit 26. The slurry and air leave the orifice 28 of the chamber 27 in a vortex at high speed creating a vacuum causing air to be sucked in through conduits 25, 32. Any of the conduits 25, 26, 32 may be connected to a conduit for the supply of flotation reagent to the tanks 6. Within the chamber 27, the air dissolved in the water becomes separated and forms fine air bubbles on the hydrophobic surfaces of the particles of the desired material thus increasing the speed of flotation of these particles in the tank 6. If insufficient slurry is being fed to the vortex generators 5 a further quantity may be provided from the front part of the tank 6 by means of a conduit 11 and adjustment of a valve 12. Slurry to be recirculated is withdrawn through an adjustable pipe 13 and regulating valve 14 by means of a pump 15 which delivers it through conduits 16, 17 to a second group of vortex generators 18. The poor quality concentrate collected in the froth in the part of the tank above the generators 18 is delivered on to a froth chute 9 from which the froth passes through a conduit 10, pump 2 and pipes 3 to the first group of vortex generators 5. The high grade final concentrate is collected in the froth in the part of the tank above the generators 5, the froth being discharged via a froth chute 8. Discharge of the froth may be effected by means of paddle wheels 7, Fig. 2. Tailings left in the tank are discharged via a conduit 19a and an overflow 19b. Two other arrangements of vortex separators in flotation tank are described.

摘要： 1,181,392. Water filter. SIMONACCO Ltd. 7 March, 1967 [21 March, 1966], No. 10571/ 67. Heading B1D. Water is filtered by passage horizontally from inlet chambers 3, 4 to outlet chambers 16, 17, 18 through downwardly moving columns of sand, the sand being continuously lifted up pipe 28, by injecting air through screen or valve 32, and delivered to the open top of container 2, from which it descends down constriction 23. The water is delivered from an overhead tank, so some water rises up constriction 23, washing the sand clean and leaving the container through outlet 26. The side walls of chambers 3, 4 consist of inclined plates, and the walls of chambers 16, 17, 18 are perforated, and may be covered with cloth, to exclude the sand.
