Center to wall is layered rapidly, assembles to center less than the cleaned coal of separating density, discharges into overfall, more than separating density
Material to wall is moved, Jing one section of underflow opening into two-stage nitration cyclone after material is selected again, sub-elect middle coal and spoil.
But, in above-mentioned prior art three products heavy medium cyclone be used for two-stage nitration sorting heavy-media suspension density compared with
Difficulty reaches separating density requirement, as a result causes to mix a certain amount of cleaned coal in product of coal in two-stage nitration cyclone, reduces cleaned coal product
Rate, to coal preparation plant economic loss is caused.If cleaned coal is selected again in the middle coal that can be obtained from two-stage nitration cyclone overfall, it is possible to
Avoid cleaned coal from losing, and also cleaned coal, middle coal, middle coal can not can be obtained by disposable sorting in prior art and select essence again
The coal separation cyclone of four kinds of products of coal and spoil.
Utility model content
The purpose of this utility model is to provide a kind of four products heavy media coal separation cyclone, and it can be in original three product
On the basis of cyclone in two-stage nitration coal realize select again, so as to once sort can realize cleaned coal, middle coal, middle coal select again cleaned coal and
Four kinds of products of spoil.
Its technical solution includes:
A kind of four product heavy media coal separation cyclones, it includes one section of cyclone, two-stage nitration cyclone and connecting tube, described one
Section cyclone is cylindrical shape, and on one section of cyclone charging aperture, discharging opening one and discharging opening two are provided with, wherein, discharging opening
One top for being located at one section of cyclone, for cleaned coal discharge, discharging opening two is located at the bottom of one section of cyclone, is used for
Material and heavy-media suspension will be again selected to discharge, the discharging opening two is connected by connecting tube with the charging aperture of the two-stage nitration cyclone
Connect, the two-stage nitration cyclone includes eddy flow guide cylinder and the eddy flow cone for connecting up and down, the charging aperture of the two-stage nitration cyclone is opened
It is located at the side of the eddy flow guide cylinder, the top of the eddy flow guide cylinder is double overflow tubular construction, the double overflow tubular construction
Including outer overflow pipe and interior overflow pipe, the outer overflow pipe and interior overflow pipe are coaxial with the eddy flow guide cylinder, the outer overflow
Manage for the slightly larger middle coal of density to be discharged, the interior overflow pipe is used to discharge the less cleaned coal of density, the eddy flow cone
Bottom be provided with underflow opening for spoil to be discharged.
Used as a preferred version of the present utility model, above-mentioned eddy flow guide cylinder and the eddy flow cone are coaxial.
The Advantageous Effects that this utility model is brought:
By arranging double overflow tubular construction at the top of two-stage nitration cyclone eddy flow guide cylinder, the little cleaned coal of density is from interior overflow
Bank of tubes goes out, and the larger middle coal of density is discharged from outer overflow pipe, and the maximum spoil of density is discharged from underflow opening, solves middle ribbing essence
The technical barrier of coal, it is to avoid cleaned coal loss, improves clean coal yield;Cyclone once sort can and meanwhile obtain cleaned coal, middle coal,
Middle coal selects again four kinds of products of cleaned coal and spoil, solves the problems, such as ribbing cleaned coal in two-stage nitration, greatly reduces cleaned coal loss, improves
Select factory's clean coal yield;Internal-external double-overflowing pipe is coaxial configuration, can run thick problem with effectively solving overflow, improves overflow sorting essence
Degree;Eddy flow guide cylinder, eddy flow cone are coaxial with internal-external double-overflowing pipe, can improve sharpness of separation.
This utility model simple structure, technological process is short, and plant maintenance is convenient, and power consumption is low, and equipment investment is little.
Description of the drawings
This utility model is described further below in conjunction with the accompanying drawings:
Fig. 1 is the structural representation of this utility model coal separation cyclone;
In figure, 1, charging aperture, 2, discharging opening one, 3, discharging opening two, 4, interior overflow pipe, 5, outer overflow pipe, 6, eddy flow is oriented to
Cylinder, 7, eddy flow cone, 8, underflow opening.
Specific embodiment
The utility model proposes a kind of four products heavy media coal separation cyclone, in order that advantage of the present utility model, skill
Art scheme is clearer, clear and definite, and this utility model is elaborated with reference to specific embodiment.
As shown in figure 1, the product heavy media coal separation cyclone of this utility model four, is led to by one section of cyclone, two-stage nitration cyclone
Cross connecting tube to be in series, the profile of one section of cyclone is cylindrical shape, and in columnar side the charging aperture 1 of tangent line is offered,
Top offers the discharging opening 1 for cleaned coal to be discharged, and offers for will again select material and heavy-media suspension in bottom
The discharging opening 23 of discharge, is connected by connecting tube at discharging opening 23 with the charging aperture of two-stage nitration cyclone, and two-stage nitration cyclone is by mutual
Two parts composition being connected, is respectively eddy flow guide cylinder 6 above and underlying eddy flow cone 7, as this reality
It is double overflow tubular construction at the top of eddy flow guide cylinder 6 with new main improvement, double overflow tubular construction includes outer overflow pipe
5 and interior overflow pipe 4, outer overflow pipe 5, interior overflow pipe 4 are coaxial with eddy flow guide cylinder 6, during actual coal separation, outer overflow pipe
For the slightly larger middle coal of density to be discharged, interior overflow pipe is used to discharge the less cleaned coal of density, and the bottom of eddy flow cone 7 is arranged
There is the underflow opening 8 for spoil to be discharged.
The course of work of above-mentioned coal separation cyclone is as follows:
Heavy-media suspension and raw coal tangentially enter one section of cyclone with certain speed from charging aperture 1 under a certain pressure
Interior, material does high speed centrifugation rotary motion in cylinder body, under the influence of centrifugal force, and raw coal presses different densities along cyclone
The heart to wall is layered rapidly, assembles to center less than the cleaned coal of separating density, discharges into discharging opening 1, more than separating density
Middle coal move to wall, Jing discharging openings 23 enter two-stage nitration cyclone;
Now still contain part cleaned coal in middle coal, do in the eddy flow guide cylinder and rotating flow cone body of two-stage nitration cyclone at a high speed from
The heart rotates, and centering coal sorted again, and the little cleaned coal of middle coal Midst density is discharged from interior overflow pipe 4, the slightly larger middle coal of density from
Outer overflow pipe 5 is discharged, and the maximum spoil of density is discharged from the underflow mouth of pipe 8, it is achieved thereby that cyclone is once sorted can obtain simultaneously
Four kinds of products of cleaned coal and spoil are selected again to cleaned coal, middle coal, middle coal, ribbing cleaned coal in two-stage nitration is solved the problems, such as, greatly reduce essence
Coal losses, improves and selects factory's clean coal yield.
It should be noted that any equivalent way that those skilled in the art are made under the teaching of this specification, or
Obvious variant all should be in protection domain of the present utility model.
