Background
In the flotation machine, the ore pulp treated by adding the medicament is aerated or air self-absorbed by stirring, so that some ore particles are selectively attached to bubbles, the bubbles float to the surface of the ore pulp and are scraped to form a foam product due to low comprehensive density of the bubbles attached to the minerals, and the rest part of the bubbles is remained in the ore pulp, so that the purpose of separating the minerals is achieved.
The common flotation machines are divided into mechanical stirring self-suction air type, mechanical stirring inflatable type, inflatable type and other types. However, in both the mechanical stirring self-suction air type flotation machine and the inflatable flotation machine, a stirring impeller and a stator which rotate correspondingly are arranged in the middle of a tank body of the flotation machine, and air is decomposed into a plurality of bubbles through the stirring impeller and the stator. The total specific surface area of all the air bubbles is determined by the amount of the air decomposition bubbles with the same volume, and the larger the total specific surface area of the air bubbles is, the higher the probability of the air bubbles contacting with minerals is, thereby improving the sorting recovery rate. The bubbles are decomposed by the stirring impeller and the stator of the flotation machine, the size of the bubbles is not easy to control, the bubbles are not uniformly diffused from the middle of the tank body of the flotation machine to the periphery of the tank body, and some air which cannot become smaller bubbles directly floats to the upper surface of the flotation machine to cause gas waste, so the mineral separation efficiency is restricted. In addition, because the bubble is dispersed to mix gas, liquid, solid and medicine, a higher power is needed to drive the stirring device to complete the mixing, and the input power consumption is large. Meanwhile, the bubbles rise linearly due to low density, the route is simple, the rising time of the bubbles is too short at the same height of the flotation machine tank body, and the probability of contact with ore pulp is further reduced. The bubbles rising to the upper surface of the flotation machine are easy to aggregate into large bubbles and are not easy to break, so that the next step of defoaming and foam circulation is difficult. Because the stirring impeller and the stator of the stirring device of the flotation machine are used for stirring ore pulp, sucking air (relative to a self-suction flotation machine), dispersing bubbles and the like, the linear speed of the impeller is higher, the energy consumption is higher, the abrasion is quicker, and the consumption cost of a wearing part is increased.
