Abstract

The utility model provides a new style shaking table with double curved-corrugation riffle which belongs to equipment of the flowing film mineral concentration. The shaking table with double curved-corrugation riffles is characterized in that two upper oblique strip regions are added, single straight-line riffles are changed into two straight riffles and two double curved riffles, which is suitable to concentrate ore faces of 3-0.019 millimeters granularity, such as non-ferrous metal, rare metal and noble metal. When pulp is fed, the oblique strip regions compels mineral particles to climb steel bars reversely in longitudinal motion, the oblique water flow climbing causes the enlargement of climbing speed difference and departure angle difference between the light mineral particles and the heavy mineral particles. Parallel strip region makes ore concentrate belt thin and even and makes the ore concentrate be discharged in time, sorting condition is improved, and processing ability and mineral concentration yield rate are obviously improved under certain sorting index.

Description

Shanking table with double curved-corrugation riffling

The design's hyperbolic ripple bed shaking table belongs to a kind of film concentration shaking table.

Shaking table belongs to the film concentration kind equipment.The U.S. in 1890 develops the earliest and is used for coal separation.The shaking table that ore dressing is used is to be succeeded in developing by Weir not sharp (A.Milfley) in 1898.China just brought into use shaking table from 1913, to nineteen fifties, shaking table is that feature is established one's own system with its assymmetric motion (back and forth), use increasingly extensive and occupied advantage, be mainly used in processing tungsten, tin, coloured, rare and precious metal ore, effectively sorting particle size range is 3～0.019 millimeters, multilayer and centrifugal table also are used to sort ferrous metal ore and coal, how to improve tabling efficient, be to be related to the key that makes full use of national resources and continue voluminous useful metal mineral, many for a long time scientific workers carried out a lot of improvement and research to shaking table once, comprised perfect to shaking table riffling section configuration and arrangement form, for example: in order to improve selected effect, obtain the higher concentrate of grade, all make riffling into oblique layout; And, then riffling is covered with whole length of bed surface or the like in order to reduce tailings grade and to improve treating capacity.In May, 1975, the utility model designer comrade You Minghui once designed industrial single band waveform shaking table, obtain good effect, but its structure was also not very good.

The purpose of the utility model patent is: provide a kind of improved hyperbolic ripple riffling structure shaking table at the deficiencies in the prior art.Make its structural parameters more reasonable.

The design's hyperbolic ripple riffling shaking table is that the single straight line riffling branch that shaking table is original is truncated into four sections, be arranged to two oblique two flat hyperbolic ripple (Binary Bending Wave) shapes, promptly have one section slanted bar district, one section oblique parallel strip district, two sections parallel strip districts He Guangmian district five parts.Only need on original equipment, to change the riffling arrangement form and change the longitudinal gradient of bed surface own, and bed surface appearance and size is constant with making.Hyperbolic ripple riffling shaking table comprises that a framework by steel-wood structure (13) and face are coated with the bed surface (12) of epoxy resin glass-ceramic diabase material and the main body (1) formed, the pin (9) of supporting shaking table, shaking table recliner adjuster (10) moves back and forth drive assembly (11) and constitutes.It is characterized in that: the riffling on the main body (1) is to be arranged to two oblique two flat hyperbolic waveform shapes, i.e. one section slanted bar district (4), one section parallel strip district (5), two sections slanted bar districts (6), two sections parallel strip districts (7) He Guangmian district (8).Hyperbolic ripple riffling sorts object by difference and chooses different technical parameters, according to vertically reciprocating.When ore materials is added by feed launder (2), directly flow down shaking table face slanted bar district (4), ore pulp is flowed to the e direction by a, the washing clear water is given fashionable by feed trough (3), be covered with bottom (d) under the cross-current of shaking table face top (c) then the riffling that is in tilted layout of slanted bar district force ore particle when lengthwise movement, the oblique current climbing that causes against the reflex bar is in this process, it is big to be in the impulsive force that the light ore particle on upper strata is subjected to, and it is little to be in the impulsive force that the heavy ore particle of bottom is subjected to.Thereby light, heavy grain climbing speed is poor, bed surface vertically, lateral velocity difference and weight ore particle depart from angular difference and also all increase, so it is more perfect that ore particle separates, so ore particle is in the process of climbing, being washed the effect of current is overturn, the light ore particle that is clipped between heavy ore particle is constantly washed out, shortened the distance that light ore particle is discharged institute's warp, improved the efficiency of separation.Simultaneously, the slanted bar district makes long-pending big minimizing of no ore faces, has improved the utilization rate of driving end bed surface effectively.Two sections parallel strip districts widen the concentrate band, and the part concentrate needn't be covered whole process along diagonal as on common shaking table face, just can in time discharge from two sections parallel strip districts (7).Unlikelyly poured in the ore deposit, make concentrate tape thickness attenuate, avoid being detained and index sharply worsens by lateral current.Owing to cleverly riffling is pressed different pinching angle (α ₁, α ₂, α ₃α ₄) and gradient (θ ₁, θ ₂) be arranged to two oblique two flat hyperbolic waveform shapes,---flat---tiltedly---flat track replaces, quilt repeatedly " squeezes ", " cutting ", " washing " to make ore along tiltedly, and this itself be make 0 ° 30 '～1 ° 10 ' head fall, so force the concentrate end to be climbing state once more, thereby be able to improve in fact greatly the sorting condition, disposal ability and ore dressing casting yield under certain sorting index control improve significantly.The design's hyperbolic ripple riffling shaking table, the shaking table bed surface of its prior art changed into vertically by original plane and have 0 ° 30 '～1 ° 10 ' the gradient after, by the bed surface of installing hyperbolic ripple riffling shown in Figure 1, the main body that (1) among the figure is made up of bed surface (12) and framework (13), (2) are feed launders, (3) are feed troughs, (4), (6) are the slanted bar districts, (5), (7) be not all right district, (8) are the Guang Mian districts, each partly Size Distribution be B ₁Be 1830mm, B ₂Be 1500mm, B ₃Between 300-400mm, L ₁Be 4520mm, L ₂Between 400-500mm, L ₃At 1320-1620mm, L ₄Between 500-800mm, L ₄Between 1900-2100mm; The angle that each is regional: α ₁Between 32 °-37 °, α ₂Between 39 °-47 °, α ₃Between 48 °-55 °, α ₄Between 49 °-56 °, θ ₁Between 7 °-12 °, θ ₂Between 7 °-15 °.The design's shaking table, when handling the mineral of proportion in the 4.7-7.2 scope, its angle θ ₁, θ ₂Between 7 °-11 ° is good, during precious metals such as processing gold, silver, and its angle θ ₁, θ ₂Between 11 °-15 °, be advisable.The design's hyperbolic ripple shaking table, the efficiency of separation can improve effectively in one section and two sections slanted bar districts, and the no ore faces that dwindles driving end is long-pending, finally improves the bed surface utilization rate; And two sections parallel strip districts that increase cloth in the Guang Mian district have improved the distribution of concentrate, shorten the discharge distance of part concentrate, to accelerate the velocity of discharge of concentrate, avoid the loss of big and heavy ore particle simultaneously.When adopt 0 ° 30 '-1 ° 10 of stroke 12-18 millimeter, jig frequency 280-320 time/minute, cross fall 2-3.5 degree, head fall ' the technology operating condition time, under the constant situation of rich ore rate, roughly selecting the comparable common shaking table of operation in unit interval increases disposal ability 60-120%, improves ore dressing yield 5-6%; Selected operation then disposal ability and ore dressing casting yield can improve 20-40% and 5-10% respectively.

The design's hyperbolic ripple shaking table has ore dressing disposal ability height, ore dressing casting yield height, advantages such as wide adaptability.
