Description
Technical Field
The utility model relates to a mechanical stirring formula coal slime flotation device technical field specifically is a force mechanical stirring flotation device impeller of breathing in.
Background
The froth flotation is a general method for separating minerals from micro-fine ore pulp, the flotation equipment utilizing the froth flotation comprises a mechanical agitation type flotation machine and a flotation column, the mechanical agitation type flotation machine realizes the functions of aerating, circulating and sucking and stirring and mixing fresh coal pulp through an agitation aeration mechanism,
generally, a mechanical stirring type flotation machine for coal adopts a double-layer umbrella-shaped structure impeller, an upper-layer impeller and a stator cover plate form a circulating ore pulp channel, the circulating ore pulp is inflated by sucking air from a sleeve, a lower-layer impeller sucks fresh coal slurry from a slurry suction port, the space between the lower-layer impeller and the upper-layer impeller is a fresh coal slurry channel, when the impeller rotates, the coal slurry is sprayed out from the fresh coal slurry channel, negative pressure is formed at the center of the lower impeller, the fresh coal slurry is aerated by the air suction holes arranged on the hubs connecting the upper and lower impellers, because of the rotation speed of the impeller, the flow speed of the sucked ore pulp and the turbulent flow of the fluid, the negative pressure formed at the center of the impeller is usually not enough to meet the requirement of the suction quality of the flotation, thereby causing the flotation process to achieve the expected effect, therefore, increasing the aeration stirring capacity of the impeller of the flotation machine is an important technical direction for improving the performance of the flotation machine and improving the effect of the flotation process.
Therefore, design a mechanical stirring formula flotation device impeller that can accomplish the lower floor and inhale by force to improve the flotation device performance, stabilize the flotation process effect, be a technological problem that the coal flotation field needs a long time to solve.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a solve the not enough technical problem of ability of current mechanical stirring flotation device impeller lower part of using coal, provide a force mechanical stirring flotation device impeller of breathing in.
The utility model discloses a realize like this, a force mechanical stirring flotation device impeller of breathing in, its characterized in that: the blade-type blade-free propeller comprises a hub, an upper-layer impeller, a lower-layer impeller and a back-locking impeller, wherein a knife handle type blade is arranged on the upper-layer impeller, a first arc-shaped blade is arranged in the space between the upper-layer impeller and the lower-layer impeller, a pulp sucking port is arranged at the center of the lower-layer impeller, the hub is arranged on a main shaft, an arc-shaped vent hole is formed in the hub, and a second arc-shaped blade is arranged on the back-locking impeller; the back lock impeller is provided with a back-rotating thread in the center.
When the impeller rotates, the back locking impeller with the arc-shaped blades is arranged at the center of the upper impeller and the lower impeller, when the impeller rotates, the arc-shaped blades on the back locking impeller rotate to forcibly drive the coal slurry away from the vent hole area on the hub to form vacuum, and under the action of pressure, air entering the upper impeller and near the hub enters the lower impeller space to be mixed with the sucked fresh coal slurry, so that the forced inflation process of sucking the fresh coal slurry by the lower impeller is completed, and the flotation effect is improved.
Compared with the prior art, the utility model beneficial effect who has is: the problem that the lower impeller of the conventional flotation machine for mechanically stirring coal is insufficient in air suction capacity is solved, and the effects of improving the aeration performance of the flotation machine and improving the flotation process are achieved.
