Description
Technical field
The utility model belongs to mineral floating equipment, relates generally to the ultrasonic fluidisation flotation column of a kind of graphite.
Background technology
The floatation equipment of traditional graphite production and application mainly is to continue to use agitation impeller flotator common in the ore dressing, there are many technical bugs such as the single chamber dischargeable capacity is little, aeration quantity is little, sharpness of separation is low, the interior turbulence intensity of cell body is high, froth bed is unstable in such flotation device, and the selected operation of scale graphite is had limitation.The problem that exists for solving above-mentioned legacy equipment, flotation column equipment is existing in the graphite flotation is produced in recent years uses, played the technique effect that increases aeration quantity, reduces the aspects such as turbulence intensity, but aspect the hydrophobicity that improves graphite and sharpness of separation, also had deficiency, be badly in need of improving.
Summary of the invention
The purpose of this utility model is exactly the problem that exists for above-mentioned prior art, and design provides a kind of ultrasonic fluidisation flotation column of graphite of new construction, reaches the purpose that improves graphite flotation production efficiency and graphite products quality.
Basic Design of the present utility model is, the ultrasonic fluidisation flotation column of graphite comprises the flotation cylinder, on flotation cylinder upper end, be equipped with respectively overflow mechanism and the feeding device that is communicated with the flotation column intracoelomic cavity, the ore pulp entrance of circulating pump and ore pulp outlet are communicated with the outlet of flotation cylinder bottom side ore pulp and bubble generator ore pulp entrance respectively, described bubble generator ore pulp outlet is communicated with flotation cylinder middle and lower part, the mine tailing entrance of mine tailing device is communicated with the mine tailing outlet that is positioned at flotation cylinder bottom, on in the flotation column intracoelomic cavity, dividing, lower two-layer equipped supersonic generator, described on, lower two-layer supersonic generator adopts mutual alternation control structure.
The utility model adopts supersonic generator emission ultrasonic wave, sound wave feeds water the energy transmission, the water vibration, aqueous vapors etc. cause the collecting agent on the graphite to change more evenly absorption, and hydrophobicity is improved, in the froth bed after the bulla fragmentation, gasification has formed minute bubbles in water, slowed down the merger effect of bubble, slowed down the phenomenon that mineral are carried secretly after reuniting, so the graphite concentrate grade has been improved; Water obtains the dither energy, this energy makes and has separated graphite in spoil, raising graphite ore active-energy, by thermodynamics knowledge as can be known, it or not an endergonic process between particle, ultrasonic wave provides separation energy for it, so, under hyperacoustic effect, the ore that is adsorbed on the graphite granule surface has produced with graphite and has separated, for graphite purification provides facilitation; Two-layer supersonic generator replaces continuous operation by turns can avoid and reduce the supersonic generator damage; That this flotation column has is simple in structure, operation is reliable and stable, operating cost is cheap, good product quality, characteristics that production efficiency is high.

Accompanying drawing is the ultrasonic fluidisation flotation column of graphite General allocation structure schematic diagram.
Piece number explanation among the figure:
1, circulating pump, 2, flotation cylinder, 3, bubble generator, 4, supersonic generator, 5, feeding device, 6, overflow mechanism, 7, mine tailing device.
The specific embodiment
Below in conjunction with accompanying drawing the utility model optimum implementation is described in detail.The ultrasonic fluidisation flotation column of graphite comprises flotation cylinder 2, on flotation cylinder 2 upper ends, be equipped with respectively overflow mechanism 6 and the feeding device 5 that is communicated with flotation cylinder 2 inner chambers, the ore pulp entrance of circulating pump 1 and ore pulp outlet are communicated with the outlet of flotation cylinder 2 bottom side ore pulps and bubble generator 3 ore pulp entrances respectively, described bubble generator 3 ore pulps outlet is communicated with flotation cylinder 2 middle and lower parts, the mine tailing entrance of mine tailing device 7 is communicated with the mine tailing outlet that is positioned at flotation cylinder 2 bottoms, on in flotation cylinder 2 inner chambers, dividing, lower two-layer equipped supersonic generator 4, described on, lower two-layer supersonic generator 4 adopts mutual alternation control structure.
During operation, graphite, ore, water three-phase fluid-mixing (hereinafter to be referred as ore pulp) is entered in the flotation cylinder 2 by feeding device 5 gravity flows, deflector in the feeding device 5 slows down the impulsive force of pan feeding, ore pulp is under the effect of deflector, by 2 peripolesises of middle mind-set flotation column body, the bottom of flotation cylinder 2 is connected with circulating pump 1 feeding mouth, ore pulp is under the effect of circulating pump 1, flotation cylinder 2 inner bottom part ore pulps are drawn onto in the circulating pump 1, circulating pump 1 impeller High Rotation Speed, ore pulp is accelerated rotation obtain energy, discharged by the outlet of circulating pump 1 ore pulp, the high-speed motion ore pulp enters bubble generator 3, and bubble generator 3 produces a large amount of micro bubbles, graphite, ore, water, bubble four phase mixtures are entered by flotation cylinder 2 middle and lower parts, mineral surface is hydrophily in the floatation process, not with bubble adhesion, ore to the motion of flotation cylinder 2 bottoms, is discharged by mine tailing device 7 under Action of Gravity Field; Graphite belongs to hydrophobic mineral, is stained with bubble at graphite surface, and graphite forms froth bed with the top of bubble motion to flotation cylinder 2 under bubble, and graphite is discharged by overflow mechanism 6, becomes concentrate; Supersonic generator 4 is arranged in the graphite foam layer, ultrasound source is to launch ultrasonic wave, ultrasonic wave makes the water vibration, impact the graphite granule in the froth bed, the tiny ore of graphite granule attachment portion, under the sonic oscillation effect, graphite separates with the ore that adheres to, impel the ore particles in the graphite foam layer to break away from froth bed, reduced the content in the graphite concentrate.
