Material pressurization pumps out, and is pressed into through feed pipe for mortar (30) from ore pulp import (511) into participation flotation in flotation cell (51), and flotation cell
(51) bottom cycle ore pulp pumps out through underflow pump from bottom through-hole, has pressure to be injected into blending bunker (5311), sprays simultaneously
Stream drives floating agent to be mixed together into blending bunker (5311), and mixed ore pulp sprays through spraying gas absorption spray (5316)
Go out, drive the first agitator arm (5341) to rotate while sucking a large amount of gases, so as to the second of drivening rod (5342) lower end
Agitator arm (5343) Stirring ore pulp, carry out flotation activity；And the ore pulp penetrated is got rid of through again through the first agitator arm (5341)
The outward flange of impeller is discharged to after secondary mixing through flow-guiding channel (5323) and discharging channel (5333), ensures good air-breathing environment.
Flotation mineralized froth is thrown out of to float up to liquid level above flotation area backward from the blade outward flange of the second agitator arm (5343)
Place, fully accumulates in the upper end of dividing plate one (515) and dividing plate two (516), and scrapes flotation cell (51) by scraper plate (513), and not
The mineralized froth scraped is then deposited downwards to the secondary enrichment region of concentrate (517), in the secondary enrichment region of concentrate (517) of both sides under
Heavy mineralized froth then sinks down into the lower end of dividing plate one (515) and dividing plate two (516), and crosses the dividing plate one (515) respectively
Flotation area is arrived with dividing plate two (516), to realize flotation again；The ore pulp of flotation cell (51) bottom is settled down to then through under outlet entrance
One flotation cell (51) carries out flotation again.
This specification is only that the preferred embodiment of invention is described, and not the scope of the present invention is limited
Fixed, on the premise of design spirit of the present invention is not departed from, those of ordinary skill in the art make to technical scheme
Various modifications and improvement, it all should fall into the protection domain of claims of the present invention determination.
