Abstract
The process involves using an inclined cylindrical separating vessel (1) with a separating medium directed in at least two partial streams through inlet tubes into the vessel with each stream controllable independently of the other with regard to its flow parameters. The partial streams can be fed into the vessel through separate supply tubes (6,7) arranged directly adjoining one another. Each partial stream can have its own associated delivery pump.
Description
Technical field
The present invention relates to the particularly method of coal of sorting raw ore thing, promptly pass through the tubular separator of inclination supporting, want the raw material of sorting in the top from the axial importing of separator, tangentially import separating medium at lower area, form bumpy flow in separator, the part that raw material is heavy especially is distributed in the axial of lower area substantially with the tangentially and especially light part that separating medium is distributed in the zone.
Background technology
BP 2147831 and 2199518 has been described the method for the above-mentioned type, wherein adopted the tubular separator, the angle that its axially relative horizontal plane inclination is 20 °-30 °, container has two inlets, promptly import former mineral axial pipeline and be used for second of separating medium and twine the shape inlet, have near the axial pipeline that the medium inlet, is used for the low-gravity classification and be used for the winding shape outlet of high specific gravity classification.The eddy current extraction unit is arranged on and twines the shape outlet upward to remove the material of big proportion by the minimum discharge of large outlet control separating medium.The mineral of little proportion substantially axially are retained in the container and by axial pipeline and discharge.Known method can only separate the material of wide particle size range, for example, the granular material of sorting different specific weight in single separator, its granularity is between 120mm-0.5mm.
The real work mode of its method is such, product quality is according to remaining on different material constant current ratio decision really in the separator, this is subjected to the influence of separating medium especially, and the eddy current that forms because of the decision separation sequence and the flow parameter of separating medium are closely related.
Special large-scale separation container for the big flow of needs, required interactively between also satisfied technically so far solution container dimensional, eddy current, mixing and the flow parameter.
Summary of the invention
The objective of the invention is obviously to improve the particularly big capacity adjustability of different size container charge weight and the adaptability of known method.
The purpose of the above-mentioned type method is to realize like this, and promptly separating medium imports with two separating medium tributaries at least, and the flow parameter in each tributary is regulated independently of one another.
As can be seen, under all similar operating positions, realize amounting to the separation in two tributaries.
As can be seen, at least two tributaries that the present invention has a separation infeed the separating medium of separator, and the flow parameter in each tributary is adjustable, has improved its adaptation of methods.In a word, because the adjustability that present single separating medium stream still is a plurality of separating mediums to flow has improved the free degree of separator being adjusted to best enforcement state.
Each tributary is easy to different parameter adjustments to best, as quantity delivered, speed, pressure differential pressure.
In addition, further advantage of the present invention obtains like this, have the big separator that needs a large amount of separating mediums thereby promptly the separating medium of realistic model is infeeded, thereby can continue to adopt prior art, particularly small size tunable pump by the given tributary separating medium that infeeds.
Infeed separating medium by abundant adjusting and can adapt to different behaviours in service because the tributary infeeds in the two measure-alike and pipes that are set up in parallel, thereby according to purpose as regulate the pressure in tributary by the variable pump that uses.
Provide according to operating position and to finish further feature of the present invention, whole supply pipes of separating medium are not to be set up in parallel, but at least at circumferencial direction 180 degree that preferably stagger.Import on same circumference according to purpose in this case, so that the input speed vector in tributary is directly overlapping so that flow condition is adjusted to the best.
The device of implementing the inventive method comprises separator, and it has: the axial pipeline of going up the zone that is used for the sorting raw material; The tangential inlet that is used for the lower area of separating medium; The axial pipeline that is used for special light fraction raw material at lower area; Be used for separating medium and the tangential outlet of heavier feedstocks part especially in last zone; It is characterized in that: inlet is divided into two supply pipes, the flow parameter independent regulation of each supply pipe at least.
Description of drawings
The embodiment that further describes the sorting bone coal that is schematically illustrated by accompanying drawing of the present invention is provided.Wherein:
Fig. 1 shows and is used for the ore-sorting system that the mine contains pit coal and coal.
The specific embodiment
In ore-sorting system shown in Figure 1, raw coal is general approximately with zone on 20 °～30 ° separators that are obliquely installed by axial pipeline 2 inputs.
The necessary separating medium of sorting is as the mixture by microgranular weight such as magnetic iron ore or ferrosilite and water, and its proportion is tangentially imported separators by the inlet 3 that the supply pipe 6,7 that is set parallel to each other by two is formed between material coal that will separate and mineral.
Equally, can add another supply pipe 8 and/or replace in the pipe 6 and 7 one, in the present embodiment, its pipe 8 and pipe 6 180 degree that stagger are provided with.
The described flox condition of separator inside forms centrifugal force field, make that heavy particle is that mineral are pressed against the marginal zone, lightweight coal is retained in interior stream district, center, subsequently, coal as product is discharged from the lower area of separator 1 by axial pipeline 4, and mineral material mixes with separating medium, by tangential passing away 5 drain separators 1.After connect in the cyclone separator 9 separation of material subsequently, the gangue that falls leaves separator through path 10.The function of described separation system depends on flox condition required in the separator 1 fully, and it is determined according to the separating medium of input.Adjusting by each tributary of the present invention is the location of independently given pattern input channel, make required flow parameter be transferred to the best, therefore another advantage is, selected separating medium amount for big separation system can be regulated each input pipe like this promptly can adopt little device of input quantity of the prior art such as pump.
