Description
Technical field
The utility model is related to one kind to have pressure three products heavy medium cyclone, it is adaptable to sorting of the height containing cash raw coal, belongs to
Screening installation technical field.
Background technology
At present, three products heavy medium cyclone has been widely used in the sorting of coal.Common are three products of pressure
Heavy medium cyclone is in series by one section of two product cylinder type cyclone and a cylindrical section pyramid type cyclone, its raw material
It is pre-mixed with suspension and is entered in a cylindrical section type cyclone and sorted, overflow obtains low-density level product, underflow enters two
In cylindrical section pyramid type cyclone, used as intermediate density level product, underflow is used as height for the overflow of two cylindrical section pyramid type cyclones
Density level product.The mounted angle of one section cylinder type cyclone（Central axis and horizontal plane angle）Generally 20 °, two sections of circles
Cylinder pyramid type cyclone mounted angle be（Central axis and horizontal plane angle）0°.
But continuous improvement and fat coal with mining mechanization degree is gradually decreased, colm, sulphur coal and
The exploitation ratio in complex geologic conditions coal seam increases increasingly so that the feed coal quality into coal preparation plant is gradually deteriorated, and sorting is difficult
Degree gradually increases.When being sorted to raw coal containing cash high using existing three products heavy medium cyclone, needed to original before sorting
Coal carries out discharge refuse so that coal preparation technique becomes complicated, increased the sorting energy consumption of raw coal, therefore studies and a kind of be capable of first discharge refuse
Three-product cyclone is very necessary.
Utility model content
The purpose of this utility model is the drawback for prior art, there is provided it is a kind of be capable of first discharge refuse have three products of pressure
Heavy medium cyclone, to simplify the sorting process containing cash raw coal high, reduces sorting energy consumption.
Problem described in the utility model is realized with following technical proposals：
One kind has pressure three products heavy medium cyclone, and composition includes one section of cyclone and two sections of cyclones, both at
The cylinder pyramid type cyclone of pressurized feeding, one section of cyclone overflow pipe is entered by the connecting tube tangent with it with two sections of cyclones
Expects pipe is connected；Two sections of cyclones are provided with filling pipe, and the filling pipe and two sections of cyclone feeding pipes are on two sections of cyclones
Axisymmetrical.
Above-mentioned to have pressure three products heavy medium cyclone, one section of cone angle of cyclone cone is 20 °~70 °, one section of cyclone
Mounted angle be -15 °~15 °.
Above-mentioned to have pressure three products heavy medium cyclone, two sections of cone angles of cyclone cone are 20 °, two sections of installations of cyclone
Inclination angle is 0 °~15 °.
The utility model is using two pressurized feeding cylinder pyramid type cyclones being connected in series directly to raw coal containing cash high
Sorted, discharge refuse need not be carried out to raw coal before sorting, so as to reduce the complexity of coal preparation technique, reduced high containing cash
The sorting energy consumption of raw coal.Additionally, the utility model can also shorten run duration of the spoil of hardness is bigger in cyclone, subtract
Few connecting tube and two sections of abrasions of cyclone, the service life of extension device.
Brief description of the drawings
The utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the top view of Fig. 1.
In figure it is each marked as：1-one section of cyclone cylinder；2-one section of cyclone cone；3-one section of cyclone underflow opening；
4-one section of cyclone feeding mouth；5-one section of cyclone overflow pipe；6-connecting tube；7-two sections of cyclone cylinders；8-two sections of rotations
Stream device cone；9-two sections of cyclone underflow openings；10-two sections of cyclone overfalls；11-filling pipe.
Specific embodiment
The utility model is made up of two pressurized feeding cylinder pyramid type cyclones being connected in series, with three traditional products
Heavy medium cyclone is compared, and improvements of the present utility model are：1. one section of big cone angle cyclone dense medium suspension of utilization
Concentrated, improved one section of separating density, reached the purpose of first discharge refuse；2. one section of discharge method of cyclone overflow pipe is carried out
Improve：Tangentially it is open in overflow tube wall（Referring to Fig. 2）, make full use of eddy flow overbottom pressure material is divided into two sections of cyclones
Choosing, and filling pipe 11 is set at two sections of axisymmetricals of cyclone feeding pipe, to reduce by two sections of heavy-media suspension density, reach
To two sections of purposes of separating density of regulation.
Referring to Fig. 1 and Fig. 2, the one section big cone angle of cone angle cylinder cone cyclone is in 20 °~70 °, mounted angle (center
Axis and horizontal sextant angle) between -15 °~15 °, the cone angle of two sections of conventional cylinder cone cyclones is 20 °, mounted angle
(central axis and horizontal sextant angle) is between 0 °~15 °.Dense media is provided with one section big cone angle cylinder cone cyclone front end
Suspension inlet（One section of cyclone feeding mouth 4）And outlet（One section of cyclone overflow pipe 5）, the other end be provided with weight product outlet
（One section of cyclone underflow opening 3）, one end of two cylindrical sections cone cyclone is provided with intermediate product outlet（Two sections of cyclone underflows
Mouth 9）, the other end be provided with light product outlet（Two sections of cyclone overfalls 10）And add clear water pipe（Filling pipe 11）, one section with
Two sections of cyclones are connected in series with pipeline, and once sorting obtains weight product, three kinds of products of intermediate product and light product.
During utility model works, heavy-media suspension is with raw coal mixture by one section of cyclone feeding mouth 4 with certain
Speed tangentially feeds one section of cyclone, and heavy-media suspension is improved by one section of concentration of cyclone, separating density, weight product cash
Stone is discharged from one section of underflow opening of cyclone.One section of overflow of cyclone enters two sections of cyclones through connecting tube 6, due to through one section
The heavy-media suspension density for entering two sections of cyclones after cyclone concentration is higher, so giving two sections of cyclones by filling pipe 11
Clear water is added, to reduce by two sections of density of heavy-media suspension.The intermediate product that two sections of cyclone sortings are obtained, i.e., middle coal is by it
Underflow opening is discharged, and light product is that cleaned coal is discharged by its overflow pipe.
One section of cyclone cylinder 1 of the present utility model and two sections of diameters of cyclone cylinder 7 are according to disposal ability
Difference determines.
