Abstract
The utility model discloses a high-speed disk type separator and relates to a centrifugal mineral processing device. The high-speed disk type separator comprises a motor, a rotary drum housing, a transmission device, and a rotary drum assembly, wherein the rotary drum assembly is arranged in the rotary drum housing and comprises a spindle, a working disk assembly and a rotary drum, the spindle vertically passes through the vertical center position of the rotary drum, the spindle is hermetically and fixedly connected with the lower end of the rotary drum, the upper end of the rotary drum is an opening, and the working disk assembly is mounted in the rotary drum. After mineral pulp is processed and deslimed, the content of particles with the diameter of less than 15 Mum in the separated materials is 10-25%, and the content of particles with the diameter of larger than 15 Mum in the overflowed/discharged mineral mud is less than 10%, the desliming efficiency is high, the metal particles with relatively large specific gravity are mainly concentrated in setting sand, the content of overflow metal is obviously lower than the content of metal in fed mineral, and the metal loss is small.
Description
Technical field
The present invention relates to a kind of centrifugal beneficiating equipment, be specially a kind of high speed disc separator.
Background technology
According to world resource situation, no matter be black, coloured or rare metal ore, abundant ore source is increasingly exhausted, poor, assorted, particulate is contaminated ore and is increased year by year, and all day by day trend towards difficult choosing, therefore fine grinding ore deposit must become the measure with common point improving mineral processing index and must take, fine grinding ore deposit will inevitably cause the increase of sludge amount simultaneously.From economic point of view, in fine grinding sludge (74-10 microns), useful metal mineral must recycle, and sludge can cause rear road flotation difficulty, so desliming is a kind of method eradicating sludge impact.
Centrifugal beneficiating equipment is the novel product that the class occurred in gravitational separation equipment in recent years reclaims useful metal mineral in trickle sludge.Sludge is difficult to carry out sorting in gravitational field, centrifugal separation is the large tens times of even hundred times of the centrifugal force force of gravity that utilizes ore particle suffered in centrifugal field, and the principle combined with film concentration is to carry out sorting.Its appearance solves the difficulty reclaiming valuable mineral from (74-10 microns) subparticle.
Main desliming bucket or hydrocyclone two kinds of equipment of adopting carry out desliming at present, but its desliming efficiency is lower, and selected material clay content is higher, target minreal loss late is bigger than normal, is unfavorable for the raising of technique of preparing economic indicator.Desliming process conventional at present adopts hydrocyclone (or desliming bucket) to carry out a desliming, in its sand setting (or underflow), < 10um grain size content is generally 20-30%, and in overflow, > 10um grain size content is generally more than 30%.Classification matter efficiency only about 50%, the > 10um grade loss late about 20% of a water conservancy cyclone desliming process, the desliming effect of desliming bucket is poorer.
Summary of the invention
The object of this invention is to provide a kind of desliming efficiency high, the high speed disc separator that metal loss is little.
The technical scheme realizing above-mentioned purpose is: a kind of high speed disc separator, is characterized in that: comprise motor, rotary drum case, transmission device and drum assembly; Described drum assembly is placed in rotary drum case, drum assembly comprises main shaft, scratch diskette assembly and rotary drum, and main shaft is vertically placed through the vertical centred position of rotary drum, and the lower end of main shaft and rotary drum is sealedly and fixedly connected, the upper end of rotary drum is opening, and described scratch diskette assembly is arranged in rotary drum; Described motor is connected with main shaft by transmission device;
Scratch diskette assembly comprises scratch diskette support, scratch diskette gland and some taper type scratch diskettes, described scratch diskette support comprises top linkage section and lower taper section, described scratch diskette support casing is contained in rotary drum, the inwall of scratch diskette support is provided with supporting rib, scratch diskette support is supported on the bottom of rotary drum by the supporting rib of bottom, the taper type scratch diskette of described some successively stacked on top of one another is added in the lower taper section of scratch diskette support, every two adjacent taper type scratch diskettes are provided with equidistant gap, described scratch diskette gland is sleeved on the taper type scratch diskette of the superiors, the lower end of scratch diskette gland and the upper port of rotary drum are sealedly and fixedly connected,
Described main shaft is equipped with feed pipe, described feed pipe passes the intracavity inter-connection of rotary drum case and drum assembly and rotary drum from the top down successively, gap is left as overfall between the upper end of described scratch diskette support and the upper end of scratch diskette gland, the bottom of rotary drum is provided with spigot, described rotary drum case is provided with superposed spill cavity and is positioned at the sand setting chamber of bottom, the lower end of the spill cavity of described rotary drum case is provided with the overflow be connected with described overfall and exports, the lower end in the sand setting chamber of described rotary drum case is provided with the sand setting be connected with described spigot and exports.
Ore pulp enters in drum assembly by feed pipe, heavy phase particle is deposited on taper type scratch diskette and forms sand setting under the high speed centrifugation power effect of disc type separator, sand setting slides along scratch diskette inner surface and departs from scratch diskette to sand setting exit in rotary drum and move discharge, enters flotation operation.As the sludge of light phase particle then under the internal pressure difference effect of rotary drum parts, discharge from the overflow of rotary drum parts outlet.
The present invention utilizes Stokes' law in centrifugal force field, sorts according to sand setting is different from the Stokes sinking speed of sludge.Due to sludge particle diameter mainly less than 10 microns, the particle diameter of sand setting is mainly between 10-74 microns, and density is also different.
Ore pulp is after process of the present invention, after desliming, in selected material, < 15um diameter particle accounts for about 10-25%, be greater than 15um diameter particle in the sludge that namely overflow removes and account for less than 10%, desliming efficiency is high, and the larger metallic particles of proportion to be mainly enriched in dirt upper, overflow tenor is starkly lower than to ore deposit, and it is little that metal damages water.
