Detailed description of the invention
Flotation column of the present invention comprises shower water assembly, to ore deposit system, cylindrical member and Tailings System, and, flotation column also comprises at the bottom of flotation column tapered pole and multiple flotation column aerator (see Fig. 4), 8 bottoms being positioned at flotation column at the bottom of flotation column tapered pole, at the bottom of flotation column tapered pole 8 cone at the bottom of downwards in infundibulate, top edge welds with the inwall of cylindrical member.At the bottom of flotation column tapered pole, 8 to provide an ample space position for the configuration of flotation column aerator, ensure that aerator can many circle distribution on the differing heights position in this space; And can promote that in flotation column, ore pulp is discharged smoothly, prevent mineral grain from piling up.
Multiple flotation column aerator 7 is arranged at the bottom of tapered pole, as shown in Figure 4, multiple flotation column aerator 6 is vertically mounted on the differing heights position at the bottom of described flotation column tapered pole, and the many circle distribution at the bottom of described flotation column tapered pole, in the embodiment shown in fig. 6, flotation column aerator 6 is equally distributed.
See Fig. 5, be set with wear-resistant steel pipe 9 in end (in the embodiment shown in Fig. 5, wear-resistant steel pipe 9 is sleeved on flotation column aerator 7 and protrudes part at the bottom of the tapered pole) distribution of multiple flotation column aerator 6.The turbulent flow produced when wear-resistant steel pipe effectively avoids high speed and high pressure gas to mix with ore pulp and the percussion caused inflator end from the ore pulp that cylinder conical lower portion flows out fast, prevent aerator from wearing and tearing.
During use, the gases at high pressure from air compressor machine pass through aerator and spray in flotation column at a high speed under the effect of aerator nozzle, mix with the ore pulp in flotation column.On the differing heights position of flotation column conical lower portion, the aerator of many circle distribution overcomes traditional flotation column aerator in the single drawback produced that circumferentially distributes of flotation column cylinder wall, the gas dispersion degree be filled with in flotation column is significantly improved, not by the impact of flotation column cross section size.The percussion that the ore pulp that the wear-resistant steel pipe being welded on flotation column conical lower portion in advance effectively slow down turbulent flow and the outflow fast bottom cylinder produced when high speed and high pressure gas mixes with ore pulp causes inflator end, extend the service life of flotation column aerator, enhance the stability of equipment.
