Detailed description of the invention
Be described in detail of the present invention below in conjunction with accompanying drawing.
As shown in Figure 1, the invention provides a heavy metal species gravity treatment enrichment pipeline, it comprises a cylindrical shell 1, and these cylindrical shell 1 two ends are respectively iron ore feeding hole 11 and go out mine mouth 12, respectively passes through to close 3(into ore deposit lid 2 and ore removal cap seal and sees Fig. 4).Be provided with some layers of ore dressing working face 4 in this cylindrical shell 1 vertically, preferably, this each ore dressing working face 4 is equidistantly arrangement in this cylindrical shell 1.The rectangular tabular of this ore dressing working face 4, both sides are located on the supporting track (figure does not illustrate) of this cylindrical shell 1 inner surface, and this supporting track can be a L-type angle steel.As shown in the figure, this cylindrical shell 1 is divided into openable two parts, middle by gemel connection, easy disassembly.
As shown in Figure 2 and Figure 3, the upper surface of this ore dressing working face 4 is provided with some parallel fins 41, and direction is axial vertical with this cylindrical shell 1.This fin 41 cross section entirety is at right angles trapezoidal, and this right-angled trapezium a that goes to the bottom overlaps with this ore dressing working face, and this fin 41 has the facade vertical with this ore dressing working face towards one end of this iron ore feeding hole, and the high H of this facade is 2mm.Further, on the right-angled trapezium cross section of this fin 41, the high h of this right-angled trapezium is 6-10mm, and a that goes to the bottom is 14-16mm, and upper base b is 2mm, and the hypotenuse c that this working face is corresponding is 19-22 ° with the angle theta of a that goes to the bottom.Preferably, the high h of this right-angled trapezium is 8mm, and a that goes to the bottom is 16mm, and the hypotenuse c that this working face is corresponding is 20 ° with the angle theta of a that goes to the bottom.
This fin 41 is working face towards the inclined-plane of this iron ore feeding hole 11, and this working face is provided with comb 5, and direction is vertical with this working face, for passive combing ore pulp, makes it to keep loose layering.Ore pulp flows through from this working face, and lower boiling water dropping shock is inner system dynamics, and repulsion between fluid layer, shear force are interacted, and excites that mine particle group is loose to raise up, and forms fluidised form high frequency change forever motive force.The high 2mm of this comb 5, is spaced apart 1.5mm.Do not connect mutually bottom this fin 41, the spacing of adjacent lugs 41 is 2mm, and between adjacent lugs, form trapezoidal cell.
As shown in Figure 4, this enters ore deposit lid 2 and is provided with and corresponding with each this ore dressing work face enters pipe 21 and sparge pipe 22, and respectively this enters the middle part that pipe 21 leads to corresponding ore dressing working face, and collects and be communicated to by ore bucket 6.Respectively this sparge pipe 22 is positioned at the side of this ore dressing working face, and is provided with the water jet corresponding with each trapezoidal cell position vertically, and cylindrical shell 1 opposite side arcuate space is concentrate carrying intercept passage.This ore removal lid 3 is provided with ore outlet pipe, for flowing out ore pulp.
As shown in Figure 5, the present invention also provides a heavy metal species gravity treatment enrichment pipeline, and comprise several above-mentioned heavy metal gravity treatment enrichment pipelines, each cylindrical shell is integrated to be fixed together, and this respectively enters pipe and all collects and be communicated to this by ore bucket 6.
The present invention separately provides a kind of described heavy metal gravity treatment enrichment pipeline beneficiation method, and it comprises the following steps:
The number of described heavy metal gravity treatment enrichment pipeline is selected according to workload; Respectively enter pipe be all switched to described by ore bucket by described, see Fig. 1 by the suspension ring 7(for lifting that electric block and this cylindrical shell are arranged), iron ore feeding hole one end of described heavy metal gravity treatment enrichment pipeline is promoted to described cylindrical shell horizontal by 20 °; Open and start for ore pulp by ore bucket, with 20 minutes for interval, stop for ore pulp, described heavy metal gravity treatment enrichment pipeline is set level, overturning 30 ° makes the sparge pipe side of described ore dressing working face higher than opposite side, then by water jet to spraying-rinsing in described trapezoidal cell, the concentrate in trapezoidal cell is rinsed to described cylinder body bottom and flows into concentrate pond; By described heavy metal gravity treatment enrichment pipeline to returning upset 30 °, the iron ore feeding hole one end continuing to promote described heavy metal gravity treatment enrichment pipeline is promoted to horizontal by 20 °, carries out next circulation.Because the multilayer ore dressing working face rate of recovery can up to more than 95%, its number of plies, width press pipe diameter setting, and pipeline thickness, length, integrated stacked system, quantity can set flexibly by production scale, condition.
Reselection technique system is optimized in industrialization transition that heavy metal gravity treatment enrichment pipeline of the present invention is formed, why can at high-recovery, high throughput, optimize concentration ratio to complement each other, create new peak, surmount hydrogenation flotation, mainly by hydrodynamics, Principles of Statics and the scientific thought catching the main aspect of principal contradiction to deal with problems on the whole, implement to create gravity treatment mechanism and excavate fluid inner system dynamics, optimize the loose layering of ore pulp, break away from the limitation of design philosophy custom tendency, the longitudinal direction be arranged on ore dressing working face lengthens, transversely arranged drop formula " positive and negative light and shade double trapezoid " cell, and be the cell dimension angle of strengthening fluid inner system dynamics, the particularly angle of working face and ore dressing working face, for combing ore pulp, the accurate comb arranged, its height, soft or hard, spacing distance, all test by applicant the optimum value drawn hard.Adopt multiple-limb to integrate in heavy metal gravity treatment enrichment pipeline in addition, more adapt to the needs of high throughput, high efficiency production.Above aspect obtains the surprising effect that 1+1 is greater than 2, and the domestic and international heavy metal general character difficult problem such as high investment, low output, heavily contaminated that especially Gold Mining Industry can't resolve is readily solved.
The present invention solves the general character difficult problem that gold steps on heavy metal mining industry high investment, low output, heavily contaminated on the whole, reverse " shake, turn, shake, put " machine power that gravity treatment be unable to do without, assert the habit set that hydrogenation flotation can not be substituted in the dominant position of Gold Mining Industry, with a set of innovation gravity treatment mechanism, deeply excavate fluid inner system dynamics.Traditional gravity treatment elite and emerging original creation gravity treatment mechanism are concentrated among the gravity treatment enrichment pipeline of the multiple-limb accessible site that can set on demand by the present invention, it is applicable to rock gold, alluvial gold, raw ore mine tailing and other heavy metal containing golden inclusion enclave comprehensively, and the sorting of subparticle level heavy mineral, its rate of recovery is high, treating capacity is large, concentration ratio is better than hydrogenation flotation mode, and compact conformation, capable of expansion and contraction, operation, dismounting, carrying are nimble, cheap, adapt to the generally urgent need of the overall technological transformation of heavy metal mining industry, particularly Gold Mining Industry.
It is pointed out that above-mentioned embodiment is only possible embodiment, in order to be expressly understood that principle of the present invention proposes.Many changes and amendment can be carried out to the embodiment of the invention described above when not deviating from the principle of the invention and scope.All such modifications and change are all included in the scope of the present invention's announcement, and are subject to the protection of claims.
