Description

Impeller of miniature flotation machine

Technical Field

The utility model relates to a flotation machine, in particular to an impeller of the flotation machine.

Background

The flotation machine is a kind of equipment for mineral separation under the condition of gas-liquid-solid three-phase, and is mainly composed of driving device, stirring shaft system, impeller, stator and tank body. The flotation machine mainly realizes the suspension of ore pulp and the mineralization of useful minerals by the collision of bubbles in a flotation tank through impeller stirring. The flotation machine impeller bears the functions of energy input, bubble generation and dispersion, ore pulp suspension and the like, and is the most key part of the flotation machine. With the continuous development of the large-scale flotation equipment, the impeller needs to bear larger torque, and the structural design and the performance design of the impeller need to have the characteristics of good separation performance, high strength, long service life, low energy consumption and the like.

The impellers in the prior art are all composed of single blade structures, and the centrifugal force and the flow stabilizing effect are poor; the traditional blade is easily influenced by material flow during stirring, the flow stabilizing effect is poor, and the centrifugal force of the blade is reduced, so that the flotation efficiency is influenced. Because long-term stirring collides with the material, the energy consumption of the stirring equipment is increased, and the collision force on the blade section is large, the blade is seriously abraded, and the service life of the blade is influenced.

SUMMERY OF THE UTILITY MODEL

The utility model provides a micro-flotation machine impeller which can improve the effect of enhancing the steady flow and prolong the service life of blades.

The technical scheme of the utility model is as follows:

a micro-flotator impeller comprising: a central shaft, an impeller cover and a plurality of guide blades;

the impeller cover is in a hollow cylindrical shape;

the guide blades are bonded with the impeller cover, the bottom plane of each guide blade and the bottom plane of the impeller cover form an angle of 15 degrees, and the guide blades and the impeller cover form a relatively closed space;

the guide impeller is in threaded connection with the central shaft;

the guide impeller and the impeller cover can rotate synchronously with the central shaft.

Optionally, the number of the guide vanes is 4, and the guide vanes are uniformly distributed along the circumferential direction of the central shaft.

Optionally, the impeller housing is of plexiglass material.

Optionally, the guide vane is made of organic glass.

Optionally, the guide vanes and the impeller shroud are bonded using chloroform.

The utility model has the beneficial effects that:

according to the embodiment of the utility model, through the stationary flow structure that blade and impeller shroud formed, form relative airtight space, make the ore pulp that the impeller centrifugation came out be "M" type three-dimensional circulation under the stationary flow effect in the inslot turbulent flow field, the bubble is evenly distributed in the inslot, and the flow state is reasonable. Meanwhile, in the process of suspension circulation of ore pulp, the impeller cover directly collides with the blades through solid substances in the blocking part of the ore pulp, so that the service life of the blades can be prolonged to a certain extent.
