Abstract
The utility model relates to an effective dehydration swirler composed of a feeding device, a separating device, an underflow device and an overflow device. The effective dehydration swirler is mainly characterized in that two upper and lower tapers are arranged on the separating device, and different taper angles are respectively adopted; the underflow device adopts a cone column shaped structure, and the taper angle is also different from the angle of the separating device. Compared with the prior art, the dehydration effect is obviously improved.
Description
Affiliated technical field
The utility model relates to a kind of separation and screening installation, in particular for the cyclone of mine ore dressing factory tailings dewatering.
Technical background
Existing general dehydration cyclone is made up of feed arrangement, overflow mechanism, separator, underflow device etc., and separator is the key component of dehydration cyclone, and the main dehydration of mine tailing is here finished.It is made up of two cones up and down, the cone angle of cone identical (standard cyclone cone angle is 20 degree), and the bottom of separator is the underflow device, generally also is to be 20 cones of spending angles.After ore pulp entered cyclone with certain speed by feed pipe, because action of centrifugal force, fine particle stage material and most water were discharged from overflow pipe, become overflow, and the coarse fraction material is discharged from underflow opening, becomes sand setting.Thickening efficiency and effluent concentration are two indexs weighing the cyclone dehydrating effect, require the dehydration cyclone usually under higher dewatering efficiency situation, obtain the overflow of low concentration.But effect is unsatisfactory in the actual use of the cyclone of this structure, and especially when the mine tailing granularity was thin, dehydrating effect was poorer, in order to reduce effluent concentration, have to carry out the two-stage dehydration sometimes, and the two cyclones series connection is used.
Summary of the invention
In order to solve the existing problem that the cyclone thickening efficiency is low, effluent concentration is high, the utility model provides a kind of high-efficiency dehydration cyclone.By changing the tangential velocity size of ore pulp at the different segregation sections of separator, make that the solid-liquid two-phase in the ore pulp can effectively deeply be separated, improve dehydrating effect, reduce the wearing and tearing of material simultaneously to wall, improve the service life of cyclone.
The technical scheme that its technical problem that solves the utility model adopts is: separator adopts upper and lower two cones, adopts different cone angles respectively, and to obtain maximum tangential velocity, the upper cone axial height is little, and cone angle is 20 degree, and the ore pulp rotation is quickened; Middle cone adopts 10 degree cone angles, and axial height strengthens, and to increase the internal volume of cone, the time of staying of prolongation ore pulp, makes the solid-liquid two-phase fully to be separated at this; The sand setting mouth adopts awl post composite construction, and height of column is identical with the underflow bore, and the cone angle is 25 degree, to increase tangential velocity once more, makes the enough energy of sand setting acquisition of high concentration discharge cyclone smoothly.
The beneficial effects of the utility model are:
1, the general cyclone of the thickening efficiency of cyclone improves more than 6%.
2, the general cyclone of cyclone effluent concentration is low.
3, the wearing and tearing of sand setting mouth obviously alleviate.

1. overflow pipes among the figure, 2. material feeding box, 3. cylinder, 4. upper cone, 5. lower cone, 6. sand setting mouth, 7. wearing layer, 8. feed pipe
Concrete implementing method
As shown in Figure 1, a kind of high-efficiency dehydration cyclone is made up of feed arrangement, separator, underflow device, overflow mechanism etc.Feed arrangement is linked to each other with material feeding box (2) with the involute form by rectangle convergent feed pipe (8), the top of material feeding box (2) is overflow pipe (1), the bottom is cyclone cylinder (3), the bottom of cylinder (3) is a separator, separator is made up of the last lower cone that links to each other, the cone angle of upper cone (4) is 20 degree, the cone angle of lower cone (5) is 10 degree, the upper end of upper cone links to each other with the lower end of charging cylinder, and the lower end of lower cone links to each other with the underflow device, and the inner flow passage of sand setting mouth (6) is the awl rod structure of a composite construction, the cone angle of tapering part is 25 degree, height of column is identical with the underflow bore, for increasing wearability, whole inner liner abrasive resistant layers (7) in the cyclone.
The utility model is by the improvement to cyclone separator and underflow device, dehydrating effect obviously improves, and below is the continuous operation tracking sampling average effect contrast in 36 days that same specification high-efficiency dehydration cyclone and common dehydration cyclone are applied to certain iron ore plant tailing dehydration.
| Index | The high-efficiency dehydration cyclone | Common dehydration cyclone |
| Feed ore concentration % | 21.36 | 21.36 |
| Effluent concentration % | 9.42 | 12.76 |
| Sand setting concentration % | 66.91 | 65.28 |
| Thickening efficiency % | 56.32 | 42.81 |
As seen from the above table, under same operating condition, the high-efficiency dehydration cyclone reduces by 3.34 percentage points than the effluent concentration of common dehydration cyclone, and thickening efficiency improves 13.51 percentage points, and dehydrating effect obviously improves.
