Abstract
A high density separation pressurized two-product heavy medium cyclone is structurally divided into a cylinder section and a cone section which integrally form the cylindrical conical cyclone. A low density product outlet is arranged in the upper end of the cylinder section structure, a high density product outlet is arranged in one end of the cone section structure, the horizontal installation angle of the cylindrical conical cyclone is 0-90 degrees, and the taper angle of the cone section is 25-170 degrees. Due to the fact that the cone section adopts the conical structure with the large taper angle of 25-170 degrees, the separation density of the cyclone can be improved. Heavy medium suspension liquid and ore mixture with the density being 1.8-2.4kg/L is fed along the edge of the straight section at certain speed from a raw ore feeding port under the effect of the gravity, and 1.8-2.4kg/L high density separation of the raw ore can be achieved after the raw core is separated by the cyclone. The cyclone is a gravity separation device adopting low density suspension liquid to achieve high density separation.
Description
Technical field
The utility model relates to a kind of two product heavy-medium cyclones, and particularly relating to a kind ofly has two product heavy-medium cyclones of pressure with the high density sorting that low-density suspension is realized high density sorting.
Background technology
Current, at home and abroad heavy medium cyclone has been widely used in and has chosen dividing of coal industry.Wherein, typical example is that Chinese patent application 200610102083.3 discloses " a kind of conical pressureless fed three-product dense-medium cyclone ", this pressureless fed three-product dense-medium cyclone is composed in series by one section of round platform cyclone and two cylindrical section round platform cyclones, and there is angle with horizontal plane when mounted in one section of truncated cone-shaped cyclone, and the cone angle of the cyclone of two sections of conical section is less, and in the time that installing, it also there is angle of inclination.This device is suitable for the mineral that separating density is 1.8-2.0kg/L left and right in coal production, and just can complete the object of high density sorting because it needs two sections of cyclones, and floor space is large, and maintenance cost is high.
Utility model content
Goal of the invention of the present utility model is the many defects that exist for prior art, provides a kind of separating effect high, easy for installation, and the high density sorting that just can realize high density sorting with low-density suspension has two product heavy-medium cyclones of pressure.
Realize above-mentioned purpose by the following technical solutions: a kind of high density sorting has two product heavy-medium cyclones of pressure, the structure of this cyclone is divided into cylindrical section and conical section, cylindrical section and conical section are integrated the conical cyclone of composition cylinder, the upper end of described cylindrical section structure is provided with the outlet of low-density product, one end of conical section structure is provided with the outlet of high density product, the horizontal setting angle of the conical cyclone of cylinder is 0-90 °, and the cone angle of its conical section is 25～170 °.
Further, the overall structure of described cyclone be cylindrical section upper, conical section under.
Further, the overall structure of described cyclone is inversion type, and conical section is upper, cylindrical section under.
Further, the horizontal setting angle of the conical cyclone of described cylinder is
75 °.
Further, the cone angle of described conical section is for being 45 °.
Adopt technique scheme, compared with prior art, because the tapering of the utility model conical section has adopted the pyramidal structure of 25～170 ° of large cone angles, can increase and improve like this separating density of cyclone.Making density is that the heavy-media suspension of 1.8-2.4kg/L and ore mix are under Action of Gravity Field, fed along the edge of straight section with certain speed by raw ore feeding mouth, raw ore ore, after cyclone sorting, can be realized the high density sorting of 1.8-2.4kg/L.Being specially adapted to the mineral that separating density is greater than 1.8kg/L, is a kind of gravity beneficiation equipment of realizing high density sorting with low-density suspension.The utility model is integrated the conical cyclone of the cylinder forming by cylindrical section, conical section, simple in structure, easy for installation, adopt pressurized feeding, increase the concentrated effect of cyclone, Yin Qiben device production technology is simple, production cost is low, and environmental pollution is little, and gained concentrate product grade is high.

The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described further.
In the present embodiment, this high density sorting has two product heavy-medium cyclones of pressure, and its body is integrated the conical cyclone of the cylinder forming by cylindrical section and conical section, and concrete structure is referring to accompanying drawing 1, the overall structure of cyclone be cylindrical section 3 upper, conical section 4 under.The middle part, upper end of cylindrical section 3 is provided with low-density product outlet 1, one side and is provided with raw ore feeding mouth 2.The bottom of conical section 4 is provided with the high density product outlet 5 of bell mouth shape, and the horizontal setting angle of the conical cyclone of cylinder arranges between 0-90, and the horizontal setting angle of the conical cyclone of the present embodiment cylinder is
75 °, the cone angle of its conical section is 45 °.
Accompanying drawing 2 is another embodiment of the present utility model, is that the conical cyclone of cylinder is inverted the embodiment using, and conical section 4 is upper, cylindrical section 3 under, the high density product outlet 5 of bell mouth shape communicates with underflow chamber 6, gos deep into underflow chamber 6.Low-density product outlet 1 communicates with overflow chamber 7.
Operation principle of the present utility model
Due to the cone angle of the conical section of cyclone is increased to 25～170, to utilize the be situated between advantage of large cone angle cyclone of water, utilize the active force of the wall convection cell of cyclone cone, suspension is discharged from low-density product outlet 1 with relative highdensity ore, the high density product obtaining is discharged by high density product outlet 5, and the method that the concentrate and tailings of discharge reclaims by dehydration and medium is carried out the dehydration of product and the recycling of dense media.Relatively improve the separating density of cyclone, made cyclone underflow opening can discharge more highdensity ore product.
