Description
Technical field
The present invention relates to preparation equipment technical field, particularly relate to the aerating device of a kind of agitation impeller flotator.
Background technology
Inflated type mechanical stirring flotation machine is a kind of very important preparation equipment, is widely used in non-ferrous metal, black
Sorting of metal and nonmetal deposits thing, flotation device is generally made up of actuating device, main shaft, cell body, gas tube, impeller and stator,
When flotation machine impeller rotates, in groove ore pulp from surrounding between bottom land is by impeller lower end intake impeller blade.Simultaneously by aerator
The low-pressure air fed enters between impeller blade through gas tube, air control valve, hollow spindle, and ore pulp and air are at impeller blade
Between be sufficiently mixed after, by impeller first half periphery discharge, the flow of slurry of discharge is moved obliquely upward, by being arranged on impeller four
The stator of all oblique uppers is stablized and after orientation, enters in whole trough.In the process, air is cut into carefully by stator blade wheel
Minute bubbles, bubble sticks rear mineralising with mineral grain collision, and mineral laden bubble rises to trough surface and forms foam, and foam flows to bubble
In foam groove, remaining ore pulp returns to impeller district and carries out recirculation.
In prior art, inflated type mechanical stirring flotation machine is usually in the middle part of rabbling mechanism or top is by aerator
Feed air, air through hollow spindle and be positioned at impeller bottom air distributor enter flotation device cell body, supply gas pressure 15-
70kPa.The airing form of above-mentioned prior art is primarily present following drawback: first, and low pressure feeds Airflow, and to move speed relative
Less, air does not has enough shear actions to generate minute bubbles during contacting with ore pulp, air dispersion effect is poor.Especially
Under the conditions of high-concentration ore slurry, the increase of ore pulp viscosity hinders effective dispersion of air, and this airing form is difficult to satisfied floating
Air dispersion requirement during choosing.Secondly, air has to pass through bearing body or the quill shaft of rabbling mechanism, close to bearing body
Envelope requires higher, and gas leakage oil leakage phenomenon happens occasionally；Air temperature in the pipeline process of circulation can rise to 50-100 DEG C, increases
Flotation device main shaft bearing heat radiation difficulty, causes Bearing Temperature, reduces bearing service life, can burn bearing time serious；
Again, air entrance location fixes, single, and gas charging system is difficult to realize On line inspection, must maintenance shut-downs when breaking down.
Summary of the invention
It is an object of the invention to provide the aerating device of a kind of agitation impeller flotator, the inflation flexible cloth of point of this device
Put, it is possible to realize air efficient uniform dispersion in flotation device.
The aerating device of a kind of agitation impeller flotator, described aerating device includes air compressor machine, wear-resistant steel pipe, aerator
With flotation device cell body, wherein:
Described air compressor machine is connected with described aerator, for providing pressure-air to described aerator；
One end of described wear-resistant steel pipe connects described aerator, and the other end is fixed on bottom or the side of described flotation device cell body
Wall；
The pressure-air that described air compressor machine provides is filled with institute under the protective effect of described wear-resistant steel pipe by described aerator
State in flotation device cell body.
Described aerator is multiple spot or single-point distribution on the bottom of described flotation device cell body or the differing heights position of sidewall.
The distributed quantity of described aerator is adjusted according to the cross section size of sorting process institute's air demand and flotation device.
As seen from the above technical solution provided by the invention, the inflation point flexible arrangement of this device, it is possible to realize sky
Gas efficient uniform dispersion in flotation device, thus overcome flotation device main shaft because of technical problems such as the gas leakage leakage of oils that causes of supply,
Ensure that aerating device can on-line maintenance.
