Abstract
The invention relates to a piling method for improving the stability of a uniformly blended material. The method comprises the following steps that (1) water spraying equipment sprays fog-shaped water to moisten a single layer of uniformly blended ore at a falling point; (2) with the increasing of the height of a material pile, the fog-shaped water spraying direction and a uniformly blended ore falling point position are kept consistent. A cantilever for implementing the method comprises a cantilever body, wherein a spraying pipe is arranged at a discharging opening of the cantilever body; a spraying nozzle is formed at an outlet of the spraying pipe and is obliquely arranged towards the material flowing direction of the discharging opening of the cantilever body; the spraying nozzle sprays the fog-shaped water above a single layer of material falling point position. The single layer of uniformly blended ore at the falling point position is moistened, so that the viscosity of the material is increased, the proportion of downwards sliding material is reduced, a single layer of material distribution is changed into the shape like a trapeziform from the shape of triangle, the thickness of the single layer of material distribution is improved, the speed that a piling angle is reduced is slowed, the piling angle is stabilized at about 37 degrees, the segregation phenomenon of the material in a piling process is reduced, the stability of components of the uniformly blended ore during material cutting is guaranteed, and meanwhile, the flying dust is reduced.
Description
Technical field
The invention belongs to mixed-windrowed locomotive bedding technology field, particularly a kind of stacking method and stacker boom improving mixing material stability.
Background technology
In existing cloth process, the height of mixed-windrowed locomotive stockpile in the process of windrow raises gradually, when the height of stockpile is elevated to certain distance, owing to being subject to Action of Gravity Field, the stocking angle (angle of repose) formed diminishes gradually, the stocking angle (angle of repose) of breeze is general between 35 ° to 45 °, mixed-windrowed locomotive is in windrow process, the height of stockpile raises gradually, under stockpile ideal conditions, along with the increase of material stack height, stockpile is in proportion expansion, raft individual layer cloth top and the bottom change in proportion, the stocking angle of blending ore raft is constant.But in actual production, along with the increase of material stack height, the face area of stockpile constantly increases, because blending and piling is deposited in together by various materials, material variety is different, the impact being subject to Action of Gravity Field is also different, and the material that granularity is large is more easily slipped to bottom stockpile, causes the segregation of material and the instability of composition.Show as thinning bottom, raft individual layer cloth top thickening, the stocking angle of blending ore raft constantly diminishes, and presents similar triangle state, and individual layer cloth top is excessively thin, and composition fluctuation is very large, very easily forms the segregation of material and causes the instability of composition.
Summary of the invention
The present invention provides a kind of and improves the stacking method of mixing material stability and implement the stacker boom of the method for solving in known technology the technical matters that exists.
The technical scheme that the present invention takes for the technical matters existed in solution known technology is:
Improve a stacking method for mixing material stability, comprise the steps:
1) install a sprinkler at mixed-windrowed locomotive cantilever end place, can spray spray water, direction is aim at the individual layer material of windrow on the slightly biased top of the drop point site of blending ore raft, is soaked by the individual layer blending ore at drop point place;
2) along with the height of stockpile raises gradually, stacker boom also raises accordingly, and spray water sprays direction and blending ore drop point site is consistent.
A kind of material machine cantilever improving mixing material stability, comprise boom body, the discharge outlet of described boom body is provided with shower, described shower exit is provided with shower nozzle, described shower nozzle is obliquely installed to the stream direction of boom body discharging opening, and described shower nozzle sprays the spray water be positioned at above individual layer material drop point site.
The advantage that the present invention has and good effect are: the present invention is soaked by the individual layer blending ore of shower nozzle by drop point place, the viscosity of material is increased, reduce the ratio of material slide downward, individual layer cloth is made to change approximate trapezoid into by triangle, improve cloth thickness in monolayer, slow down the speed that stocking angle diminishes, after actual use, stocking angle is stabilized in about 37 °, decrease the segregation phenomena of expecting in windrow process, when ensure that blank, blending ore composition is stable, reduce airborne dust simultaneously, improve operating environment.

Fig. 2 is mixing material planar view after spray.
In Fig. 1 and Fig. 2,1. raft, 2. stream, 3. boom body, 4. shower, 5. shower nozzle, 6. spray water.
Detailed description of the invention:
For summary of the invention of the present invention, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Improve a stacking method for mixing material stability, comprise the steps:
1) install a sprinkler at mixed-windrowed locomotive cantilever end place, can spray spray water, direction is aim at the individual layer material of windrow on the slightly biased top of the drop point site of blending ore raft 1, is soaked by the individual layer blending ore at drop point place;
2) along with the height of stockpile raises gradually, stacker boom also raises accordingly, and spray water sprays direction and blending ore drop point site is consistent.
Refer to Fig. 1, a kind of stacker boom improving mixing material stability, comprise boom body 3, the discharge outlet of boom body 3 is provided with shower 4, shower 4 exit is provided with shower nozzle 5, shower nozzle 5 is obliquely installed to stream 2 direction of boom body 3 discharging opening, and shower nozzle 5 sprays the spray water 6 be positioned at above individual layer material drop point site.
The present invention is soaked by the individual layer blending ore of shower nozzle by drop point place, the viscosity of material is increased, reduce the ratio of material slide downward, individual layer cloth is made to change approximate trapezoid into by triangle, improve cloth thickness in monolayer, slow down the speed that stocking angle diminishes, reduce airborne dust simultaneously, improve operating environment.Actual use after stocking angle be stabilized in about 37 °, as shown in Figure 2, decrease the segregation phenomena of expecting in windrow process, when ensure that blank, blending ore composition is stable.
The present invention can realize the stable of blending ore composition, and in blending ore composition, the standard deviation of SiO2 is reduced to about 0.20 by the standard deviation that former 0.3 is reduced to about 0.2, TFe by 0.25, and can increase the heap doses of raft.
Above embodiment is only in order to illustrate that technical scheme of the present invention is not intended to limit, and those of ordinary skill in the field should be appreciated that and still can modify to the detailed description of the invention of invention or portion of techniques feature be carried out to equivalent replacement; And not departing from the spirit of technical solution of the present invention, it all should be encompassed in the technology of request of the present invention protection.
