Description

A kind of mineral seperator

Technical field

The utility model relates to sorting mineral machinery field, especially relates to a kind of mineral seperator, and it is applicable to separating of high density and low-density mixture, is specially adapted to high density mineral content more difficult separation of material and high-temperature material and separates.Also be applicable to coal and spoil, pyritous separation.

Background technology

At present, domestic and international application is in industrial mineral seperator, mainly contains and in Chinese patent CN103008092, discloses separating of rough and thin ore deposit, and its medium mainly separating is water, is mainly the material that separates different-grain diameter.

In " coal preparation technology one volume " that U.S.'s Graham Sodd method of investing and Te Luoman Co., Ltd publish for 1988, a kind of adverse current separator is disclosed, it is a kind of air table, and bed surface is rectangle, and horizontal by the inclination angle of 10 °, extensional vibration device makes bed surface lengthwise movement, and bed surface is punching sieve plate.One Fans is blown to sieve is lower with constant wind speed and pressure, because making the material on bed surface, mobile air-flow upwards produces lamination, heavier spoil sees through bed and drops on sieve plate, and tilt to move up along bed surface under the reciprocating effect of bias, lighter coal floats over the top of bed, and is pushed to the direction of bed surface under being tilted to by pan feeding.This air table belongs to Air Fluidized bed, carries out a sorting on bed surface, and head coal product is once discharged, and easily sneaks into the spoil of small grain size, inferior separating effect, and productivity ratio is low, and this air table requires wind-force large simultaneously.

In addition, conventional mineral seperator also has a kind of dry type shaking table, does not adopt wind-force, only depends on material screw layering, coarsegrain on upper strata, small grain size in lower floor, poor by effect of density separation.The nineties, discloses a kind of combined type separating method, and it is to adopt autogenous medium (contained Bed for Fine Coal in feed coal) and the sorting of air composition gas-solid two-phase blending agent; Make sorting material make spiral tumbling motion by mechanical oscillation, form repeatedly sorting; And the buoyancy effect of the Interaction between particles that produces of the density that makes full use of gradually the bed material improving and carry out sorting.Material is done under the condition of spiral flip-flop movement on separator bed surface, utilized the comprehensive function of vibration force and ascending air to cause mobility of bed and ore particle by density stratification.Under Action of Gravity Field, separate top layer case of low density loads.In cyclic process repeatedly, material is subject to repeatedly sorting, through peeling off layer by layer, produces ash content multiple product from low to high, until discharge spoil and the pyrite of density maximum; Utilize again in feed coal contained fine (being called autogenous medium) to mix composition gas-solid two-phase blending agent with ascending air and carry out sorting, in this suspension media with certain density, case of low density loads floating, and high density material sinking; Also utilize the heavy ore particle buoyancy effect producing that interacts, make to sneak into the continuous emersion of coal grain in spoil layer and obtain pure spoil product.

Above-mentioned Duplex dry separator is disclosed respectively in Chinese patent CN2101532, CN2314850, the separation of the solid particle mixture that its applicable density is different.Be mainly to adopt it to be included in vibrator and the sorting bed in frame, hung, form vibrated bed body; The glazing bar consistent with material movement direction is set thereon, evenly lays vertically-supplying air hole on the bed surface between glazing bar, this vertically-supplying air hole is communicated with air chamber, connects angled back panel at the rear portion of sorting bed bed surface.Under vibration force and ascending air effect, material is for the helical movement, and by density stratification, through the sorting that repeatedly circulates, makes case of low density loads and high density feed separation.

The second, the effect of parallel glazing bar on bed surface, the appropriate design of glazing bar height and angle also has considerable influence to separating effect.One, guiding high density ore particle moves to spoil passage; Its two, improve the speed of bed bottom high density ore particle to spoil end motion, be conducive to improve sorting bed treating capacity; Its three, glazing bar can play certain sorting.The coal that bed upper strata density is little can be crossed glazing bar and move to discharge limit, and bottom high density material is under glazing bar stops, can only be along glazing bar to high density end motion, improve sharpness of separation, therefore, the appropriate design of glazing bar height and angle also has considerable influence to separating effect.

The 3rd, its bed surface is shaped as right angle pentagon, and bed surface feed hem width degree and bed surface length ratio are 4:10, causes the sorting time short, and in case of low density loads, easily containing high density material, sharpness of separation is difficult for improving.

The 4th, above-mentioned patent does not provide the angle of inclination of backboard with respect to bed surface, and the angle of backboard is for the directing material guiding that plays a part for the helical movement, the appropriate design at angle of inclination, make material there is rational screw, peeling off of light material played an important role.

The 5th, bed surface vibration mode is electric and magnetic oscillation or the vibration of short arc inertia force, is unfavorable for the material that sorting granularity is larger, lower to bed surface upper bed layer bottom material handling speed, is difficult to improve production capacity.

Along with modern industry is to the selected requirement of mineral, be badly in need of a kind of mineral isolation technics that can overcome prior art defect.
