Description
Technical field
The utility model is related to a kind of slime separation classification technique, especially a kind of liquid-solid fluid bed coarse slime size overflow
Cleaned coal desliming grading plant.
Background technology
The technique that most of coal preparation technique is combined using stepless gravity treatment with flotation in the prior art, before no matter being selected in
The sorting size limit of de- or No severing mud, gravity treatment and flotation is 0.5mm, actually due to two kinds of method for separating itself the characteristics of
So that the coal grain separating effect near 0.5mm is poor, and this part coal grain（Refer generally to 3-0.25mm）National standard（GB/T 7186-
1998）It is defined as coarse slime.This partial particulate is typically individually reclaimed in coal preparation plant by high-frequency screen, and its ash content is between cleaned coal with
Between coal, 2-5% typically higher than cleans ash, its final whereabouts is difficult to confirm.It is not sorted typically at present, it is most by its portion
Divide incorporation cleaned coal, coal in another part incorporation.Development and the demand of society with the epoch, current coal market is to coal product
Ash requirements it is more and more stricter, have a small number of coal preparation plants using minor diameter dense medium cyclone or spiral to rough coal in recent years
Mud is sorted, but the deficiency due to both devices in itself, it is impossible to reach satisfied effect.Minor diameter heavy medium cyclone
It is not enough：Too thin to medium requirements, medium prepares and reclaimed difficult and cost height；Pressure is high to be required to pan feeding, equipment attrition
Seriously, power consumption is big；Although it is sorted, granularity lower limit is relatively low, and thinner stock grading efficiency is low, and a part is not passed through
The thin mud for crossing sorting enters cleaned coal, cleans ash is influenceed, while it can not replace flotation completely.Spiral is not enough：Point
Select density high, cleaned coal can not reach the cleans ash finally required, its product cannot function as final products sale；Separate unit processing
Amount is small, it is necessary to which many use cooperatively, and floor space is big, and height is big, while needing to adjust oar and distributor, distributing uniformity is difficult to
Control；It is strict to feed thickness requirement, it is difficult to control in industrial production.
In existing coal preparation technique, the fluidization technology on chemical industry is incorporated into Concentrating Field, good effect has been achieved.
Chinese utility model patent（Patent No. ZL200720037745.0）Disclosed liquid-solid fluid bed coarse slime size classification grading device, is carried
Supply a kind of to reduce the liquid-solid fluid bed coarse slime size device of coarse slime ash content again as medium by the use of coarse slime itself.Profit
With main this relation relevant with the density of particle of its sinking speed during narrow grade material hindered falling, make material in itself institute
Sorted in the fluidizing agent of composition.Before pan feeding using classification eddy flow and choosing after using cyclone, high-frequency screen and coal slime from
There are still the high grey thin mud of a part in the desliming device such as scheming, final cleaned coal, cause high ash thin mud in pan feeding dirty to cleaned coal
Dye is serious, influences separation results.
Utility model content
The purpose of this utility model be overcome oneself to have weak point present in technology there is provided a kind of liquid-solid fluid bed rough coal
Mud sort overflow cleaned coal desliming grading plant, by coarse slime overflow product liquid-solid fluid bed coarse slime size machine overflow export into
Row sedimentation desliming, the grey thin mud pollution of height in reduction liquid-solid fluid bed coarse slime size machine overflow, so as to realize the total cleaned coal of reduction
Ash content, raising product quality and coal resources comprehensive utilization ratio.
Liquid-solid fluid bed coarse slime size overflow cleaned coal desliming grading plant of the present utility model, including sorting classifying bucket
Body, fluid distributor, overflow desliming device.
Sorting classifying staving is made up of upper barrel body, lower barrel body and base cone, and upper shell and lower barrel body are connected by flange, base cone
It is suitable for reading to be connected under lower barrel body bottom, base cone by mouth setting mine tailing valve, base cone Xia Kou sides provided with the bypass pipe controlled by draw valve.
Fluid distributor is arranged between lower barrel body and base cone, with staving outer connecting pipe UNICOM.
Overflow desliming device is made up of oblique staving, flow distribution plate and overflow launder.The flow distribution plate is inclined at oblique staving
Top, its inclination angle is consistent with oblique staving angle of inclination.Overflow launder is arranged on surrounding at the top of oblique staving, and flow distribution plate separates overflow launder
For left and right two parts, coarse content overflow pipe is communicated with overflow launder right half part, particulate thing overflow pipe and overflow launder left side split-phase
Logical, the top of upper barrel body is provided with pan feeding sleeve, and feeding pipe is enclosed in pan feeding sleeve.
The sectional area suitable for reading of the oblique staving is more than lower mouth sectional area.
The course of work:Material, even into pan feeding sleeve, sorting point is moved downwardly into by gravity by feeding pipe
In level staving.The material entered in sorting classifying staving is progressively moved downward after certain distance, and material starts the height by density
Low separation, because the lateral cross-sectional area of oblique staving is up big and down small, fluid flow velocity during rising slows down gradually, in flow distribution plate
In the presence of, fine grained moves up through peripheral overflow weir into overflow launder left-half, by installed in the thin of left-half
The overflow pipe discharge of grain thing, coarse granule moves up through peripheral overflow weir into overflow launder right half part, by installed in right side
The coarse content overflow pipe discharge divided.The thin mud of liquid-solid fluid bed coarse slime size Grading Overflow passes through the peripheral overflow on oblique bucket top
Weir enters left-half in overflow launder, and coarse-fine coal enters right side in overflow launder by the peripheral overflow weir on oblique bucket top
Point, realize desliming and the inspissation of liquid-solid fluid bed coarse slime size classifier overflow.Higher density material continues downward
Move to fluid bed bed（Fluid distributor）, density higher than fluid bed bed density material pass through bed（Fluid distributor）
Bottom is entered, mine tailing is turned into by the discharge of mine tailing valve, and the material of intermediate density is moved back and forth in bed above and below, is passed through
Separation is done step-by-step after a period of time.The formation of fluidized-bed layer is using pan feeding middle-high density material as medium, to pass through fluid
The ascending water come in distributor is fluid, forms fluid bed bed.
The utility model device, reduces the pollution of high ash thin mud in liquid-solid fluid bed coarse slime size machine overflow, and letter
Changed the follow-up desliming dewatering process of sorting, reduction cleans ash, reduce high grey thin mud to the pollution of cleaned coal, improve separating effect.
It can be achieved to sort in high precision under low-density, cleaned coal is polluted less by thin mud, and cleans ash is lower, and pan feeding ash content is below 25%
When, the cleans ash after sorting is suitable or lower with gravity treatment and floatation clean coal ash content.
