Description
Technical Field
The utility model relates to a mineral processing field. More specifically, the present invention relates to an extended range turbofan blade impinging stream mixing device.
Background
According to different aeration and stirring modes, the flotation machine can be divided into: the flotation device comprises four types of inflation mechanical stirring type flotation machines, self-suction mechanical stirring type flotation machines, decompression type flotation machines and airlift type flotation machines. Under the action of centrifugal force of the impeller, the mixed ore pulp enters the mineralization area, air forms bubbles and is crushed, the bubbles are fully contacted with ore particles to form mineralization bubbles, the mineralization bubbles are uniformly distributed on the cross section of the groove body under the action of the stator and the turbulent flow plate and move upwards to enter the separation area to be enriched to form a foam layer, and the foam layer is discharged by the foam scraping mechanism to form concentrate foam. The impeller is the most important part of the mechanical stirring type flotation machine, the impeller design mainly considers the following problems that the stirring force is moderate, and a large dynamic head is not caused in the tank. This is because the large dynamic head will cause the separation region to be unstable, the liquid level to turn over, influence the bubble mineralization, reduce the useful mineral recovery, increase the unnecessary power consumption at the same time. The circulation amount of the ore pulp passing through the impeller is large, which is beneficial to the suspension of ore particles, the dispersion of air and the improvement of the sorting index. The streamline of the ore pulp in the impeller is reasonable, and the abrasion is light and uniform. Reasonable form, simple structure and low power consumption. Another important function of the impeller is to disperse the air, for which purpose an air distributor is provided in the impeller cavity. The air distributor distributes air relatively uniformly over a large portion of the rotor blades in advance to provide a large slurry air interface, thereby improving the ability of the impeller to disperse air and increasing air dispersion, but the impeller centrifugal force is not sufficient to allow adequate contact between the particles and the air.
