A preferable scheme includes an impeller in the impeller-stator system utilizes a high specific speed backward leaning blade impeller, and a stator of in the impeller-stator system utilizes a low damping straight hanging stator. Compared with the prior art, operation power consumption per volume is reduced on the premises that pulp is suspended fully and ore grains are distributed evenly.
Description
Technical field
The present invention relates to the widely used flotation device equipment of mining industry, relate in particular to a kind of large-scale efficient inflation agitation impeller flotator.
Background technology
Mineral Resources in China is because high strength consumption for many years and extensive development and use; It is progressively exhausted to be prone to processing, high-grade resource; Poor, thin, assorted unmanageable resource yield increases greatly, and the disposal ability of newly-built ore dressing project day hits new peak frequently, even up to 100,000 t/d; Demand to large-scale floatation equipment is very urgent, and the application prospect of large-scale floatation equipment is boundless.Existing inflation agitation impeller flotator mainly is XJK type and SF type; Their ubiquitous problems are not resolve the flotation device bottom to need enough stirring intensities and top to need the contradiction between the mineral syrup liquid stably; There is magic flower in various degree in mineral syrup liquid and influences flotation effect; And thereby the bubble poor performance makes that whole stirring is not good enough, in addition, also has problems such as unit volume running power consumption is bigger.
Summary of the invention
The object of the invention is exactly not good enough and unit volume running power consumption is bigger waits deficiency and provide a kind of under the assurance prerequisite that ore pulp fully suspends, ore particle is evenly distributed in order to overcome existing inflation agitation impeller flotator mixing effect, reduced the turn round large-scale efficient inflation agitation impeller flotator of power consumption of unit volume.
The object of the invention can be realized through following technical scheme: a kind of large-scale efficient inflation agitation impeller flotator; Comprise flotation cell, air organization of supply, ore pulp feeding mechanism, rabbling mechanism and foam output mechanism, said rabbling mechanism comprises impeller-stator system.
Preferably, the impeller in said impeller-stator system adopts high specific revolution hypsokinesis blade impeller.

Preferably, said large-scale efficient inflation agitation impeller flotator also comprises the fluid level controller that the mineral pulp level in the said ore pulp feeding mechanism is controlled.
Preferably, said large-scale efficient inflation agitation impeller flotator also comprises the gas flow controller that the aeration quantity of said air organization of supply is controlled.
Preferably, said air organization of supply adopts air blast supply low-pressure air.
Preferably, said foam output mechanism adopts the mode of hanging oneself to let foam enter into chute.
Preferably, said foam output mechanism adopts the mode of machinery discharge to let foam enter into chute.
Compared with prior art, beneficial effect of the present invention is following:
1, adopt high specific revolution hypsokinesis blade impeller, internal circulating load is big, the pressure head low spot, has guaranteed that ore pulp fully suspends, ore particle is evenly distributed, and can significantly reduce the power level of flotation device.
2, adopt low damping straight suspended type stator, the unsettled zone of stator is big, has reduced the running power consumption.
3, dispose the automatic control system of mineral pulp level, aeration quantity, guaranteed that mineral syrup liquid maintains setting value, improved sorting index effectively, reduced the ore pulp short circuit phenomenon.
Description of drawings
Fig. 1 is the structural representation of the large-scale efficient inflation agitation impeller flotator of the present invention;
Among the figure: the 1st, flotation cell, the 2nd, impeller, the 3rd, stator.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is elaborated.
Embodiment:
As shown in Figure 1, a kind of large-scale efficient inflation agitation impeller flotator comprises flotation cell 1, air organization of supply, ore pulp feeding mechanism, rabbling mechanism and foam output mechanism, and said rabbling mechanism comprises impeller 2 and stator 3.
In the present embodiment; Impeller 2 adopts high specific revolution hypsokinesis blade impeller 2; Stator 3 adopts low damping straight suspended type stator 3, and the air organization of supply adopts air blast supply low-pressure air, and the foam output mechanism is provided with overfall and adopts the mode of hanging oneself to let foam enter into chute.The mode that also can adopt machinery to discharge lets foam enter into chute, for example can realize through scraper plate is set.
In the present embodiment; Said large-scale efficient inflation agitation impeller flotator also comprises the fluid level controller that the mineral pulp level in the said ore pulp feeding mechanism is controlled; Guarantee that mineral syrup liquid maintains setting value, improved sorting index effectively, reduced the ore pulp short circuit phenomenon.
In the present embodiment, said large-scale efficient inflation agitation impeller flotator also comprises the gas flow controller that the aeration quantity of said air organization of supply is controlled.
In the present embodiment; During flotation machine impeller 2 rotations, the low-pressure air that ore pulp and air blast feed in the flotation cell 1 carries out fully mixed impeller 2 first halves periphery that is incorporated in and discharges between impeller 2 blades; Permeate in the whole flotation cell 1 by stator 3 stable back entering; Mineral laden bubble is born valuable mineral and is risen to flotation cell 1 surface formation froth bed, and foam adopts from mode excessive or the machinery discharge and enters into chute, realizes the effective enrichment to the purpose mineral.Owing to adopted high specific revolution hypsokinesis blade impeller 2, its internal circulating load is big, the pressure head low spot, has guaranteed that ore pulp fully suspends, ore particle is evenly distributed, and has significantly reduced the power level of flotation device; Owing to adopted low damping straight suspended type stator 3, these stator 3 unsettled zones are big, thereby reduced the running power consumption again.
Large-scale efficient inflation agitation impeller flotator in the foregoing description is applicable to large and medium-sized ore dressing plant, adopts method for floating comprehensively to reclaim to non-ferrous metal, ferrous metal, nonmetal mineral resource.Compare with middle-size and small-size flotation device; This large-scale efficient inflation agitation impeller flotator is guaranteeing that it stirs under Reynolds number and the prerequisite that middle-size and small-size equipment equates basically; Through optimizing core component is the version and the operating parameters of impeller-stator system; Guaranteeing under the prerequisite that ore pulp fully suspends, ore particle is evenly distributed, realizing the reduction of unit volume running power consumption; 40,50,100, during 160m this large-scale efficient inflation agitation impeller flotator is in single groove dischargeable capacity:; 55,75,132,160kW corresponding installation power is:; And its actual power consumption is the 60%-75% (because of ore character and floatation process difference slightly fluctuate) of installation power; Compare with middle-size and small-size flotation device, the power level of unit flotation volume reduces 20%-30%.
