Description

A kind of minerals separation machine separation bed

Technical field

The present invention relates to sorting mineral machinery field, especially relate to a kind of minerals separation machine separation bed, it is applicable to height Density and the separation of low-density mixture, be particularly well-suited to the more difficult separation of material of high density mineral content and high-temperature material enters Row separates.It is also applied for coal and spoil, pyritous separates.

Background technology

At present, domestic and international application, in industrial minerals separation machine, mainly has disclosed in Chinese patent CN103008092 The separation in rough and thin ore deposit, its medium mainly separated is water, the material of primarily discrete different-grain diameter.

" coal preparation technology volume " that U.S.'s Graham Sodd method of investing and Te Luoman company limited publish for 1988 disclose a kind of inverse Classification machine, 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, bed surface is punching sieve plate.The air-supply under sieve with constant wind speed and pressure of one Fans, due to flowing upwards Air-flow makes the material on bed surface produce lamination, and heavier spoil falls on sieve plate through bed, and moves back and forth in bias Effect under tilt upward movement along bed surface, lighter coal floats over the top of bed, and pushed to bed surface diagonally downward by pan feeding Direction.This air table belongs to Air Fluidized bed, once sorts on bed surface, and head coal product is once discharged, and is easily mixed into little The spoil of granularity, inferior separating effect, productivity ratio is low, and this air table requires that wind-force is big simultaneously.

Additionally, conventional minerals separation machine also has a kind of dry type shaking table, do not use wind-force, only divide by material screw Layer, big granularity on upper strata, small grain size in lower floor, poor by effect of density separation.The nineties, discloses a kind of combined type and divides Selecting method, it is to use autogenous medium (contained Bed for Fine Coal in feed coal) and air composition gas-particle two-phase blending agent sorting；Borrow Help mechanical vibration to make sorting material make spiral tumbling motion, formed and repeatedly sort；And make full use of the bed material gradually stepped up Density produced by the buoyancy effect of Interaction between particles and sort.Material is made to make spiral upset on separator bed surface Under conditions of motion, the comprehensive function of vibration force and ascending air is utilized to cause mobility of bed and ore particle by density stratification.At weight Under power effect, separate top layer case of low density loads.In repeatedly cyclic process, material is repeatedly sorted, and peels off through layer by layer, Produce ash multiple product from low to high, until discharging the maximum spoil of density and pyrite；Utilize again in feed coal Contained fine (referred to as autogenous medium) mixes composition gas-particle two-phase blending agent and sorts, at this tool with ascending air Having in the suspension media of certain density, case of low density loads floats, and high density material sinking；Also utilize weight ore particle to interact to produce Raw buoyancy effect, makes the continuous emersion of coal grain being mixed in spoil layer obtain pure spoil product.

Individually disclosing above-mentioned Duplex dry separator in Chinese patent CN2101532, CN2314850, it is suitable for The separation of the solid particle mixture that density is different.It is mainly used to be included in frame the vibrator of hanging and separate bed, Constitute vibration bed body；The glazing bar consistent with material movement direction is set thereon, the bed surface between glazing bar is uniformly laid vertically-supplying air Hole, this vertical air holes connects with air chamber, connects angled back panel at the rear portion separating bed bed surface.Make in vibration force and ascending air Under with, material is for the helical movement, and by density stratification, through repeatedly circulating sorting, makes case of low density loads and high density feed separation.

Second, the effect of parallel glazing bar on bed surface, separating effect is also had bigger by the appropriate design of glazing bar height and angle Impact.One, guides high density ore particle to move to spoil passage；Its two, improve high density ore particle bottom bed and transport to spoil end Dynamic speed, is conducive to improving separation bed treating capacity；Its three, glazing bar can play certain sorting.Bed upper layer density is little Coal can cross glazing bar to discharge limit move, and bottom high density material glazing bar stop under, can only be along glazing bar to high density end Motion, improves sharpness of separation, and therefore, the appropriate design of glazing bar height and angle also has considerable influence to separating effect.

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 point Selecting the time short, the easy material Han high density in case of low density loads, sharpness of separation is difficult to improve.

4th, above-mentioned patent does not provides the backboard angle of inclination relative to bed surface, and the angle of backboard is for directing material The guiding that plays a part for the helical movement, the appropriate design at angle of inclination, make material have rational screw, to lightweight thing The stripping of material plays an important role.

5th, bed surface vibration mode is electric and magnetic oscillation or the vibration of short arc inertia force, is unfavorable for sorting the thing that granularity is bigger Material, relatively low to bed surface upper bed layer bottoms material transporting velocity, it is difficult to improve production capacity.
