Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is described in further detail:
As shown in Figure 1, a kind of new and effective jet flotation column, comprise: ore pulp pulp-inlet pipe 1, nozzle 2, negative tube 3, wear-resistant pipe 4, negative pressure inlet pipe 5, trunnion 6, ejector conduit 7, ejector support 8, cylinder 9, foam tank 10, concentrate outlet 11, pulp distributer 12, micropore foam maker 13, wedged bottom 14, mine tailing outlet 15, flange 17, ore pulp mouthpiece 18, is characterized in that: ore pulp pulp-inlet pipe 1 is made up of upper end blind plate 16, upper flanges 17, middle steel pipe 19, ore pulp mouthpiece 18 and lower end flanges 17; Negative tube 3 is made up of upper end perforate blind plate 22, middle steel pipe 19 and lower end flanges 17, wherein upper end blind plate center drilling uniform around centre bore four screw holes are set, centre bore arranges nozzle 2, and with gland 20 and screw 21, nozzle 2 is fastened, its middle steel pipe 19 side is provided with negative pressure inlet pipe 5; Ore pulp pulp-inlet pipe 1 is arranged on negative tube 3 upper end.The perforate blind plate 22 that trunnion 6 is arranged by upper and lower two ends and the middle steel pipe 19 arranged thereof form, and wherein in middle steel pipe 19, arrange wear-resistant pipe 4, the 6 times perforate blind plates 22 in wear-resistant pipe 4 lower end and trunnion are concordant, and wear-resistant pipe 4 upper end is deep in negative tube 3.Trunnion 6 is arranged on negative tube 3 lower end.The flange 17 that ejector conduit 7 is arranged by upper and lower two ends and the middle steel pipe 19 arranged form, and ejector conduit 7 upper flanges 17 and trunnion 6 times end flanges 17 are connected, and trunnion 6 lower flange 17 is connected with pulp distributer 12.During use, flotation column enters the mode that slurry adopts high-pressure spray, negative pressure cavity is produced in nozzle 2 lower end, automatically air (herein also by air compressor malleation to gas) is sucked when flotation column enters ore pulp, air enters trunnion with ore pulp and carries out preliminary mixing with ore pulp, completes first time pre-inflation; After ore pulp enters flotation column cylinder 9 by ejector, second time inflation is carried out by the micropore foam maker 13 (micropore foam maker produces bubble by compressed air) bottom flotation column ground, ore pulp is mixed more fully with bubble, substantially increases beneficiating efficiency.
