Synergistic gas mixing device for stirring type flotation machine

Technical Field

The utility model belongs to the technical field of mining flotation device equipment and specifically relates to a mix device with synergistic gas on stirring formula flotation device.

Background

The flotation machine is a short name of a flotation machine and refers to mechanical equipment for completing a flotation process. In the flotation machine, the ore pulp treated by adding the medicament is stirred and aerated to ensure that certain ore particles are selectively fixed on the bubbles; floating to the surface of the ore pulp, being scraped to form foam products, and the rest part is remained in the ore pulp so as to achieve the purpose of separating minerals. The flotation machine has a plurality of structural forms, and is most commonly a mechanical stirring type flotation machine, the flotation machine is mainly used for sorting nonferrous metals such as copper, zinc, lead, nickel, gold and the like, and also can be used for roughing and fine sorting of ferrous metals and nonmetals, and unmineralized coal particles on the bottom of the tank can be mixed, mineralized and separated again through a circulating hole and an upper suction port. And part of ore pulp which is not sucked by the impeller at the bottom of the tank enters the bottom of the second chamber through the middling box buried in the ore pulp, enters the third chamber after the whole process of the first chamber is finished, the flotation machine is repeated in this way, and the ore pulp enters the tailing tank after passing through the last chamber and is discharged out of the final tailing. Is an important device essential for a mineral separation production line. Foreign flotation equipment is also applied in China, for example, a stirring type flotation machine is of a flat-bottom cylindrical single-groove structure. The working principle is that the pretreated ore pulp enters a feed box sealed at the upper part of a trough body to form a coal pulp liquid flow vertically downwards; compressed air enters from one end of the hollow shaft and is discharged from the other end, coal slurry and air are thrown out along the blades of the impeller and guided by the stator, bubbles finish a mineralization process in the processes of stirring, throwing and rising, gradually rise to a liquid level to form a three-phase foam layer, and are discharged from a chute at the upper part of the tank body after overflowing, tailings are gathered at the bottom of the flotation machine and are discharged from a tailing discharge port at the bottom of the flotation machine, and the air is forcibly blown in by utilizing mechanical transmission and a specially-arranged fan, so that the aim of flotation is fulfilled.
