Description

A kind of flotation device

Technical field

The present invention relates to a kind of flotation device, belongs to preparation equipment field.

Background technology

Flotation, floats the abbreviation of ore dressing, is the difference according to mineral particle surface physicochemical properties, by mineral floatability The method that sorted of difference, most widely used is foam flotation method：Ore Jing is broken to make various mineral disaggregations with grinding Into monomer particle, and granular size is made to meet floatation process requirement.Various floating agents are added to the ore pulp after ore grinding and is stirred Reconcile, make to act on mineral grain, to expand the intergranular floatability difference of different minerals.The ore pulp for mixing up sends into flotation cell, Stirring inflation.Ore particle in ore pulp is selectively adhered to bubble and is carried with bubble contact, collision, the good ore particle of floatability Rising becomes the mineralized froth layer of airwater mist cooling composition, and Jing machineries are scraped or overflowed from mineral slurry level, then are dehydrated, are dried to essence Mineral products；The mineral grains such as not floaty stone-like pulse, discharge as product from failing from flotation trench bottom with ore pulp.

At present, according to<<Modern ore dressing handbook the 2nd flotation and chemical mineral processing>>(a river rising in Ningxia and flowing into central Shaanxi life chief editor, metallurgical industry are published Society) to introduce, the foam separation of existing flotation device adopts mostly trunnion axis rotor segment or adopts rake structure, makes foam overflow.

Or the centrifugal U-shaped eccentric groove that such as patent ZL01821143.7 is introduced, as shown in figure 1, in the drive of electric rotating machine Under, foam is swept, foam is risen near U-shaped bottom along inclined-plane, and now foam height is higher than edge on tank body, while in centrifugation Throw away after end is moved under power effect.This mode has the drawback that：Foam separator is rotated in foam, can be in bubble Destruction is produced in foam layer to foam, surface easily forms vortex, reduces flotation effect, affects foam stabilization, and foam has residual, has The foam not swept, causes FLOTATION SEPARATION not thorough.

To sum up, the problem that existing flotation device is present has：Piece-rate system efficiency is low, separates not thorough；System is not cleared up, is made Many into residual foam, recovery rate in ore-dressing is low, needs manual stoppage to clear up, it is impossible to enough continuous produtions；FLOTATION SEPARATION and stirring need Two motors are driven respectively, and motor rotation and working method are single, complex structure and power consumption.

The content of the invention

The deficiency that the present invention is present for above-mentioned prior art, there is provided a kind of separation is thorough, realize the intellectuality of self-cleaning Flotation device.

The technical scheme that the present invention solves above-mentioned technical problem is as follows：A kind of flotation device, including flotation cell, positioned at flotation cell Top bracing frame, the inlet positioned at flotation cell side, the slag notch positioned at flotation cell opposite side and be located at flotation cell cervical region Outer collecting tank, is provided with support beam in support frame as described above, which is characterized in that, an impeller, institute are provided with the flotation cell State impeller to be fixed on the hollow axle driven by belt pulley, the hollow axle is fixed on support frame as described above by bearing； In the hollow axle, epimere is provided with least one for being passed through the through hole of liquid and foam, is set with outside the hollow axle stage casing There is supporter, the supporter is positioned by positioner, clutch is provided between the hollow axle and the supporter； Protective shaft sleeve is set with outside the hollow axle of the clutch lower end, the supporter and the protective shaft sleeve are fixed as one, Feed liquor gap is left between the protective shaft sleeve bottom and the hollow axle, the hollow axle hypomere is uniformly provided with least two Injection through hole；The supporter periphery is uniformly fixed with least two foam separators, and the foam separator includes bubble Foam steadying plate, inclined board, non-return dam, collection swash plate and outer baffle, the foam stabilization plate of the foam separator are fixed on institute State on supporter, the section that the foam stabilization plate, inclined board, non-return dam and collection swash plate are in turn connected to form is in " entering " font Structure, the foam stabilization plate, inclined board, non-return dam and collection swash plate both sides are fixed with outer baffle；The collecting tank is by floating Select groove to be fixed on immediately below the foam separator free end, above the collection swash plate, be provided with jet pipe, the jet pipe is fixed In support beam.

The invention has the beneficial effects as follows：Foam separator is designed to " entering " font by the present invention, and foam is from foam stabilization Plate passes sequentially through inclined board, climbs over non-return dam, flows through collection swash plate, drops onto collecting tank, remaining foam energy when motor stops Enough flow in collecting tank by self gravitation；By jet pipe is fixed on above collection swash plate, realize in production process from clear Wash, realize continuous prodution；By through hole and injection through hole are arranged on hollow axle, stirring dead angle is further eliminated, by liquid Body, mineral, medicament, air etc. are sufficiently stirred for so that liquid and foam are full of whole cavity, realize separating fully, improve floating Select effect；By using clutch so that FLOTATION SEPARATION and stirring share an electric system, simple structure, energy efficient.

On the basis of above-mentioned technical proposal, the present invention can also do following improvement.

Further, the clutch is freewheel clutch.

It is that motor is rotated forward using the beneficial effect of above-mentioned further scheme, clutch is opened, and belt pulley drives hollow axle Rotation, when in flotation cell, foam reaches larger thickness, motor stops rotating forward；Motor reversal, clutch closure, belt pulley drive Hollow axle and supporter and foam separator rotation, foam is collected in collecting tank.

Further, the positioner includes electric magnet (or cylinder), lever, retaining groove and fairlead, and the fairlead is solid It is scheduled on above support beam, at the top of the supporter, is provided with retaining groove, the electric magnet (or cylinder) is connected with lever, and the lever is worn Cross fairlead, support beam to be engaged with described retaining groove.

It is that, when motor belt motor disorder of internal organs pony axle is rotated forward, lever is placed in retaining groove using the beneficial effect of above-mentioned further scheme, With fairlead clamping, supporter fixed by lever by own wt；When electric magnet drives lever to depart from retaining groove, motor belt motor disorder of internal organs is empty The reversion of rotating shaft, supporter and foam separator, starts flotation.

Further, the foam separator includes non-return dam.

It is to prevent during motor quits work using the beneficial effect of above-mentioned further scheme, foam return.

Further, the neck slot of the flotation cell is located at the middle epimere of the supporter and the through hole at.

It is to eliminate stirring dead angle using the beneficial effect of above-mentioned further scheme, by liquid, mineral, medicament, air etc. It is sufficiently stirred for so that liquid and foam are full of whole cavity, realizes separating abundant, raising flotation effect.

Further, the through hole is elongated.

Further, described flotation device also includes control system, described control system control hollow axle, supporter and Foam separator gradually slows down when ramping up in the foam course of work is gone out, stopping.
