Specific embodiment
Below in conjunction with specific embodiment, further set forth the technical solution of the utility model.
In accompanying drawing 1-3, Reference numeral 1 means that flushing type hydrocyclone, Reference numeral 2 mean that feed launder, Reference numeral 3 mean that flannelette blanket formula chute, Reference numeral 4 mean that flannelette blanket concentrate hopper, Reference numeral 5 mean that mineral-feeding pipe, Reference numeral 6 mean that mine distributor, Reference numeral 7 mean the enrichment conical surface (being commonly called as yurt).
As shown in Figure 1, enforcement comprises the steps: that according to the method for Unpowered gravity ore dressing of the present utility model the mine tailing in ore dressing plant is through 1 classification of Simple flushing formula hydrocyclone, overflow after classification is given to ore pulp respectively in the chute 3 of certain slope and width through feed launder 2, the surface of chute 3 is covered with one deck flannelette blanket, ore pulp forms the film that slips of uniform and stable on the surface of flannelette blanket, poor according to the sinking speed that the density variation of different minerals causes, the heavy mineral preferential deposition is in the fine hair formula gap of flannelette blanket, gangue mineral is along with flow of slurry is brought in mine tailing, like this after enrichment after a while, stop to ore deposit, the heavy mineral that adopts water under high pressure will be attached on flannelette blanket is flushed in flannelette blanket concentrate hopper 4, ore deposit is given in flushing again after finishing, so go round and begin again.
The heavy mineral rough concentrate of flannelette blanket output adds water move to certain pulp density, through mineral-feeding pipe 5, evenly be given in the mine distributor on the enrichment conical surface 7 (yurt) in 6, mine distributor is fast rotational under the impact of flow of slurry, simultaneously ore pulp evenly is sprinkling upon on the yurt 7 of cement, on the slope of yurt 7, form moisture film, heavy mineral is attached to the slope (smooth taper cement surface) of yurt 7, and gangue is domatic away from the slope of yurt 7.After enrichment after a while, stop to ore deposit, in one embodiment, the time of enrichment, on the slope of yurt 7, high-grade heavy mineral concentrate product in enrichment generally at 30-40 minute.
In one embodiment, the concentration that the heavy mineral in flannelette blanket concentrate hopper 4 is added to the secondary ore pulp that water concocting becomes is 10-12%; The pressure 2-3kg/cm of high-pressure washing water
2, the quantity of chute will be determined according to disposal ability, 10 meters of general flute length, wide 0.8 meter, the chute of gradient 9-11% disposal ability hourly per hour is about 1-1.5 ton (dry ore deposit amount), and after needing ore deposit to be processed amount to determine, the quantity of chute has also just calculated.The slope control of " yurt " is between 24 to 27 degree, and yurt bottom circle diameter is controlled at 3 meters left and right, and at the bottom of mine distributor, circular diameter is controlled at 0.54 meter left and right, and cone angle is controlled at 35 degree left and right.
As Figure 2-3, in the device of Unpowered gravity ore dressing of the present utility model, the parameter of " yurt " is as follows: d
1=130mm, H=891mm, h
1=100mm, h
2=400mm, h
3=267mm, D
1=3000mm, D
2=4500mm, D
3=4800mm, D
4=5200mm, D
5=5500mm.
In the device according to Unpowered gravity ore dressing of the present utility model, designed the mine distributor on a kind of flannelette blanket formula chute, yurt and yurt.After the mine tailing in ore dressing plant is carried out to classification, overflow flows into flannelette blanket formula chute automatically, through flannelette blanket formula chute, roughly select enrichment, to improve the grade of product, the rough concentrate of flannelette blanket formula chute feeds the mine distributor on yurt (the enrichment conical surface), and on mine distributor 20 gradually are recessed at fast rotational under the dynamic action of current (being flow of slurry), ore pulp are evenly spread on the slope of yurt, heavy mineral is enrichment again on slope, and the grade of product is further improved.
According to the utility model, if necessary, further yurt, like this, through the enrichment of two to three times, just can obtain the product requirement of final sales.
As shown in Fig. 4-5, in an embodiment of the present utility model, woollen blanket chute 3 to ore deposit end 12, be provided with feed launder 23 and DN80 plastics mineral-feeding pipe 11, minute ore deposit groove 24 and DN20 plastics divide pipe 10, can make mine-supplying quantity evenly be covered with whole groove 3 surfaces, be conducive to the sorting of weight mineral.
In addition on the one hand, the utility model is provided with DN80 plastics concentrate ore discharge pipe 31, DN80 plastics mine tailing ore discharge pipe 32 and DN65 plastics ore discharge intubate 33 at the mine-discharging terminal 34 of woollen blanket chute 3, operating personnel can discharge concentrate to concentrate ditch 41 by the position of adjusting intubate 33 very easily easily, discharge mine tailing to mine tailing ditch 42.
The utility model adopts the high pressure water washing flannelette blanket, has saved the operation of " put-down blanket, wash flannelette blanket and flocking blanket " of the prior art, greatly reduces employee's labour intensity.
The utility model is provided with " flushing type waterpower revolve slip device classification ", can improve the recovering effect of flannelette blanket.
As shown in Fig. 6-7, " flushing type hydrocyclone " also claims " flushing type waterpower revolve slip device " to comprise sieve-board type classification case 100 and hydrocyclone 101, can be welded also and can be built into common brick with iron plate.
The mine tailing in ore dressing plant is raised the mineral-feeding pipe 102 (for example selecting DN200) of delivering to the tangential direction that is arranged on hydrocyclone 101 by sand pump, thereby feeds in hydrocyclone 101.Because ore pulp has certain pressure and flow velocity, in mine tailing the coarse fraction tailings under centrifugal force and Action of Gravity Field wall 103 spirals along cyclone 101 move downward, when the sieve plate 105 on developing room 104 tops that approach the cone end, again under the flushing action of the water under high pressure in high-pressure intake pipe 106, only have the coarse granule tailings just can overcome the effect of ascending current and enter ore discharge pipe 107 and discharge.Remaining fine grained tailings, under the effect of ascending current, moves upward, and for example, from ore pulp overflow pipe 108 (selecting DN150), discharging, and enter blanket sluice 3, carries out ore-dressing practice, thereby has completed classification process.
