Description
Technical field
The present invention relates to a kind of special-purpose foaming device without circulating pump Washdown type flotation column, particularly calcareous collophane adopts reverse flotation to deviate from the ore deposit equipment of its carbonate impurity.The mechanical equipment technical field that belongs to mineral processing.
Background technology
High speed development along with Phosphate Fertilizer Industry, the exploitation of phosphorus ore and consumption also sharply rise, the overall grade of phosphorus ore declines day by day, causes impurity component in phosphoric acid to become more and more complicated, and exploitation mid low grade phosphate rock stone has become the task of top priority, for in low grade calcareous collophane, major impurity is carbonate impurity, and the single reverse flotation flowsheet of main employing, removes carbonate impurity at present, be enriched with ore deposit, relatively simple in collophane sorts.The flotation device that traditional preparation equipment adopts, the problem such as flotation device exists floor space large, energy consumption height; Therefore, adopting Novel flotation column is a kind of trend, and what industrial production was used often is the flotation column with circulating pump, wherein circulating pump is except having ore pulp circulation stirring effect, the bubble that circulating pump also produces foam maker has dissection, makes Air Bubble Size even, meets flotation required; But at calcareous collophane sorting process, in acid medium, carry out, adopt tradition to have the flotation column of circulating pump, the easy fouling of circulating pump, causes circulating pump fault more, and impact is normally produced; Secondly, circulating pump energy consumption is higher, increases production cost, adopts novel Washdown type flotation column, both can avoid scale formation, can reduce energy consumption again, is suitable for sorting of calcareous collophane.But, without the critical component of the flotation column of circulating pump, be foam maker, guarantee produced bubble evenly, stable, just can reach desirable separating effect.
The large-scale flotation column of current original design Washdown type, in sorting calcareous collophane production run, foam maker tolerance is inhomogeneous, foam maker outlet is single hole, aperture 0.5mm, 1.0mm, tri-kinds of 1.5mm, the restive air inflow of single hole foam maker, admission pressure will regulate and control simultaneously, air inlet hour, the bubbles volume producing is few, inhomogeneous, when large-minded, form one air-flow, cause mineral slurry level rolling, ore pulp forms turbulent flow, the effective foam of flotation is few, be difficult to form stable froth bed, flotation effect is bad, the air inflow of single foam maker is gentle is pressed with strict restriction, tolerance is at 40～50Ml, the bubble that air pressure produces at 3～4Kg is just relatively stable, secondly, foam maker only has an outlet, and perpendicular to mineral slurry level, when regulation and control air inflow, ore pulp easily pours in down a chimney and enters foaming air gun from foaming mouth, because calcareous collophane sorts, is to carry out in acid medium, the acid ore pulp that enters foam gun can corrode gun barrel, causes foam maker malfunctioning.And bottom large-scale flotation column, having many foam makers, foam maker air-flow is by long-range master control, if wherein one or a few foam maker is because stopping up or corrosion and damage, other air gun air inlet pressure is disorderly, cause bubble inhomogeneous, even produce turbulent gas column, thereby cause flotation effect poor.
Summary of the invention
The object of the invention is to overcome above-mentioned prior art not enough, a kind of special-purpose foaming device without circulating pump Washdown type flotation column is provided.
Technical solution of the present invention is: by flotation body component, foaming gun barrel, foam maker, air inlet pipe, form the special-purpose foaming device without circulating pump Washdown type flotation column, it is characterized in that: foaming gun barrel perpendicular to flotation device bottom install, foaming gun barrel outside flotation column, foam maker in flotation column, the air-flow of Long-distance Control passes through air inlet pipe, enter foam maker, by foam maker, produce even, stable bubble, bubble even dispersion is in flotation column, and evenly toward rising, for useful ore deposit is separated with impurity, provide carrier.
Foam maker and foam gun are with bolts, are convenient to dismounting; The miniature porous of its two foam maker, spontaneous bubble is many, even.
Described foam maker has 5 holes and 7 holes, 30～50 microns, aperture.
Described foam maker, because aperture is little, ore pulp is not easy to enter air gun, and therefore, air gun can not corrode, and micropore foam maker can be protected rifle body, improves the service life of integral foam air gun.
Owing to adopting miniature porous, expanded device, foam maker head is porous and Kong Weiwei footpath, as long as control admission pressure, just can produce even, stable bubble, forms the needed stable froth bed of flotation, guarantees that flotation is effectively separated.
The invention has the beneficial effects as follows: realized the commercial application that new technology, new equipment sort at calcareous collophane, employing is without circulating pump, Washdown type flotation column, not only reduce floor space, but also can save energy consumption, thereby significantly reduced construction investment expense and the operating cost of suitability for industrialized production; Flotation device consumption is few on year-on-year basis, reaches energy-saving and cost-reducing object;
(1) reagent consumption is low, and index is good;
(2) this technological process is simple to operate, and equipment maintenance is convenient, greatly cuts operating costs.

The specific embodiment
The feature of calcareous collophane: the major impurity of calcareous collophane is carbonate (MgO), the single reverse flotation of main employing removes carbonate impurity at present, thereby reach removal of impurities, is enriched with the object with ore deposit, and flotation froth is impurity, in groove, product is concentrate, according at present selected head grade P
20
519.0～22.0%, MgO 6.0～8.0%, and when concentrate grade is in 28.0～29.5%, MgO≤0.8% left and right, concentrate yield>=60%, meets and press down many floating few flotation principles, and it is relatively simple that the collophane of comparing other type sorts flow process; For the present invention, new technology, new equipment sort calcareous collophane, can reach energy-saving and cost-reducing object.
The problem thin in conjunction with collophane feed particle size, relative viscosity is large, adopts the floating post of novel Washdown type of development voluntarily, at airing form, done improvement to ore deposit mode, ratio of height to diameter etc.; Especially on critical component foam maker, done significant improvement, the bubble producing is even, stable, is applicable to Collophanite flotation.
The present invention is mainly that innovative point is also without circulating pump Washdown type flotation column process:
1, novelly without circulating pump Washdown type flotation column, adopt exclusive foam maker, without circulating pump in the situation that, the Air Bubble Size producing is even, and in flotation column, dispersivity is fine, can have the flotation column effect of circulating pump suitable with import;
2, adopt the Washdown type flotation column without circulating pump, circulating pump, saving investment and operation cost in the middle of reducing, the impact on the running of floatation process continuity such as circulating pump obstruction, fouling in the middle of simultaneously also reducing;
3, employing porous micropore foam maker, the foam producing is even, stable, and flotation liquid level is steady, can form stable froth bed, is conducive to smart mine tailing separation and effective control tailings grade;
4, foam maker and foam gun are with bolts, and dismounting is simple, are convenient to maintenance, cleaning, change, and reduce production costs;
5, simple to operate, energy consumption is low, be easy to control.
