Description
The utility model relates to a kind of floatation equipment of mine ore dressing operation.
The used flotation machinery in mine is varied, and rotation inflatable, jet injecting type, air pressing type, self-priming etc. are arranged, flotation mode difference, and structure is different.As " cyclone formula flotation column " (notification number 2096416), its top is the flotation column of being made up of the plurality of sections pipe, and the bottom is a hydrocyclone.A wash water pipe is introduced at the flotation column top, and dispenser is arranged at top.Cyclone top have one with the tangent circular hole of cyclone inwall, circular hole place dress air ejector, the bottom connects the mine tailing drainage conduit.But not only sorting microfine of this flotation column coal also can be used for coal slime flotation and desulfuration operations.
The purpose of this utility model is intended to design a kind of flotation efficiency height, energy consumption is low, easy to operate, applicability is strong, the requirement of applicable complex multi-metal mineral, refractory minerals, coarse grain and mineral particles flotation.
The purpose of this utility model realizes that in the following manner the powerful flotation device of bispin comprises injector 1, cell body 4, foam tank 5, foamed pipe 13, tailings discharging pipe, control valve.Injector connects mineralising pipe 21 time, and mineralising pipe pipe end is communicated with pulp distributer 6 with cell body 4 bottoms, and several piece adjusting-flow board 3 is equipped with on cell body top.Foam tank 5 is positioned at cell body 4 central authorities, and its underpart is in mine tailing cone 7, and foamed pipe 13 is arranged at the bottom.There is center mine tailing bucket 16 in foam tank central authorities, and cell body and upper bracket 18 joint portions are passed in mine tailing bucket top, center, debug joint handwheel 17 on it, and last tailings discharging pipe 11 is arranged at the bottom.Dress screw mandrel in the middle of the adjusting handle, screw mandrel is dress float controller valve 15 down, center debris tube 14.The mine tailing cone connects down mine tailing delivery pipe 87 times.Ore pulp feed box 19 is arranged, little bellows chamber 20 on the upper bracket 18.
Accompanying drawing is the utility model structural representation.
With reference to accompanying drawing, injector 1 has three kinds of slurry source jet ejectors, air source jet ejectors, micropore cross-flow injector, they are formed by the 1a of balancing gate pit, mixing chamber 1b, pressure stabilizing chamber 1c (or trunnion), and difference is that voltage-stablizer central authorities or periphery are equipped with jet nozzle or micropore aerator.Below three kinds of injectors are introduced respectively:
1, slurry source jet ejectors: ore pulp is oriented in a tangential direction by elevator pump and enters injector pressure chamber 1a, produces high speed ore pulp spiral cylindricality jet beam through the jet nozzle in mixing chamber 1b, forms negative pressure in mixing chamber.Air is oriented in a tangential direction vorticity and is wrapped in the skin of jet beam from the adjustable flashboard of mixing chamber inlet, because the abrupt pressure reduction and the volume sudden expansion that are produced when forming jet beam, is wrapped in the outer field air of jet beam and dissolves in ore pulp and produce micro air bubble.Mineralisings reactions such as strong collision, contact have taken place in mineral, flotation agent, the air in the ore pulp at this moment, thereby its flotation speed exceeds 20 times than traditional flotation device.
2, air source ejector: operation principle is the same, different is: air is compressed into tangent line (or centering direction) through air compressor and enters and be pressed into chamber 1a, ore pulp is pressed into through the tangent line inlet of elevator pump from mixing chamber, and the ore pulp vortex of formation is wrapped in the skin of air-spray bundle.
3, micropore cross-flow injector: can divide outside injection and entad injection by the air emission direction, divide peripheral annular charging of micropore aerator and micropore gas tube central feeding by the ore pulp mode of entrance.Now with regard to air outwards spray, the charging of ore pulp annular sprays operation principle and is described below: compressed air is pressed into the micropore gas tube from the tangential inlet that is pressed into chamber 1a, fine bubble is to the annular space injection of the interior week of mixing chamber 1b, and the pressure ore pulp that promotes through elevator pump becomes vorticity to form staggered the contact through micropore aerator peripheral annular space with micro air bubble.At this moment, mineralising reactions such as strong collision, contact take place in micro air bubble, mineral, floating agent, thereby its flotation speed is very high.
The ore pulp that comes out from injector is after mineralising pipe 2 mineralisings, evenly distribute by pulp distributer 6, become the tangential direction of variable-angle to enter cell body from cell body 4 bottoms, and rotation at a high speed in cell body, the micro air bubble that is produced by rotation in seconds is dispersed in the cell body each several part with vortex.Mineralising foam rise to cell body top froth zone rapidly and form good froth bed, then from the foam tank 5 that is left to cell body center or periphery, discharge through bottom foamed pipe 13, flotation concentrate product or half product.Cell body, mine tailing cone 7, pulp distributer 6 are fixed on the lower carriage 12, and lower carriage is fixed on the underframe 10.
The mine tailing that is sorted out, up from the bottom of mine tailing cone 7 along center debris tube 14, by debris tube top, center adjusting handle 14, adjustment float controller valve 15,, froth bed is controlled in the 200-600mm thickness with this height of controlling the flotation liquid level.Mine tailing is again from the float controller valve center mine tailing case 16 that enters suitable for reading, and tailings discharging pipe 11 is discharged from the bottom, as the mineral that wherein do not floatingly select in addition, then it is entered in next operation flotation device with ore pulp again.
The following mine tailing delivery pipe 8 of coarse grained refractory minerals in mine tailing cone 7 discharged.Be equipped with mine tailing valve 9 on the following mine tailing delivery pipe,, control the closed circuit mine-supplying quantity, thereby improve the rate of recovery with the rotary speed of ore pulp in the effluxvelocity of regulating injector, the cell body with this in order to the flow of regulate discharging.Compressed air and ore pulp are assigned to injector 1 by ore pulp feed box 19 and little bellows chamber 20.
The air inlet of advancing to starch of the utility model injector enters for the tangential direction vorticity, and jet beam is a helical form, has increased the degree of dissolving of ore pulp and air, has improved flotation efficiency.
Ore pulp is by the tangential feed of cell body periphery, and ore pulp produces rotation at a high speed in cell body.Several clip slots are arranged at cell body 4 tops, and the clip slot interpolation is found several piece adjusting-flow board 3.Regulate the eddy flow state of ore pulp by the size of regulating the degree of depth that adjusting-flow board inserts and ore pulp charging tangential angle, ore pulp internal circulating load, face forms wheel streaming, half spiral-flow type or three kinds of fluidised forms of non-spiral-flow type, improves flotation efficiency.
Mine tailing in the mine tailing cone is discharged from last debris tube through center mine tailing case from valve is suitable for reading along flowing to the mine tailing control valve on the debris tube of center, and the mine tailing route is short, and debris tube is difficult for stopping up, and the flotation liquid level is regulated flexibly.
The utility model novel structure, flotation efficiency height, energy consumption are low, convenient and reliable operation, production capacity is big, applicability is strong, applicable to the complex multi-metal mineral, and various mineral such as refractory minerals, coarse grain and particulate.
