Abstract
The invention provides a three-product dense medium cyclone. A cyclone body is in a cylinder-cone structure and comprises a feeding pipe, a straight section, a base cone, a tailing outlet, a concentrate outlet and a middling outlet, wherein the cyclone body is internally provided with two central pipes; the two central pipes are concentric and embedded together and are placed at the central part in the cyclone body. According to the three-product dense medium cyclone, the two central pipes are designed and the diameters of the two central pipes are different; a lightest product is discharged from the central pipe; the products with great density are discharged from a space between the two pipes. An overflowed product is divided into two products with different densities so that selected minerals are divided into three products and the aim of sorting the three products is realized. The device adopts the cylinder-cone up-down structure so that the sorting of the three products of the minerals is realized, the occupied area is reduced, the structure is simple and the installation is convenient.
Description
Technical field
The present invention relates to a kind of cyclone separator, particularly relate to a kind of three products heavy medium cyclone.
Background technology
Existing three products heavy medium cyclone, its structure is as Fig. 2, mostly adopt two two product cyclones to be composed in series, this hydrocyclone structure complexity, take up an area space large, bring inconvenience to installation and technological design, and be the central tube that arranges of this cyclone, make two sections of product qualities be not easy to control, affect service efficiency.
Summary of the invention
Goal of the invention of the present invention is for prior art complex structure, the deficiencies such as installation bothers, occupation of land space is large, provide and in a kind of cyclone body, be provided with two central tubes, externally only need a suspension feeding mouth, can realize the three products heavy medium cyclone of three kinds of different products of sorting simultaneously.
Realize above-mentioned purpose by the following technical solutions:
A kind of three products heavy medium cyclone, this cyclone body is cylinder, conical structure, cyclone body is provided with mine tailing outlet, concentrate outlet and chats outlet, cyclone body is connected with feeding pipe, two central tubes are set in described cyclone body, and two central tubes with one heart and nest together, are placed in the centre in cyclone body.
Two described central tubes are connected with cyclone inside respectively.
The diameter difference of two described central tubes.
The cylinder circular cone of described cyclone body is up-down structure, and cylindrical structure is upper, conical structure under, cylinder, conical structure are integrated.
Described cylindrical structure top is provided with chats outlet and concentrate outlet, and the middle part of cylindrical structure is communicated with feeding pipe, and being positioned at the bottom of the cone of the conical structure below cylindrical structure is that mine tailing exports.
Adopt technique scheme, compared with prior art, remarkable result of the present invention is: because the present invention adopts two central tube designs, because two central tube diameter differences, the lightest product is discharged from the pipe at center, and the product that density is slightly large is got rid of from the space between two pipes.Overflow product is divided into again to the product of two kinds of different densities, thereby selected mineral have been divided into three kinds of products, realized the object of tertiary industry sorting.This device adopts cylinder circular cone up-down structure not only to realize the sorting of three kinds of products of mineral, and has reduced floor space, simple in structure, easy for installation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure, mark is as follows: mine tailing outlet 1, circular cone 2, feeding pipe 3, central tube 4, concentrate outlet 5, chats outlet 6, straight section 7.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention will be further described.
The invention discloses a kind of three products heavy medium cyclone, its design philosophy is: a nested central tube again in the former central tube of cyclone body, the central tube of composition double-pipe body structure is realized the object of three products sorting.
Concrete structure is shown in Fig. 1.
This three products heavy medium cyclone body is cylinder, circular cone 2 structures, and cylinder, circular cone 2 are up-down structure, and cylindrical structure is upper, conical structure under, cylinder, conical structure are integrated.Adopt cylinder conical structure, can utilize a kind of suspension of density to sub-elect three kinds of different densities products simultaneously.
The nozzle middle part of cylindrical structure is provided with concentrate outlet 5, and a side of nozzle is provided with chats outlet 6.Middle part straight section 7 parts of cylindrical structure are communicated with feeding pipe 3.Being positioned at the bottom of the cone of conical structure of cylindrical structure below is mine tailing outlet 1.The present embodiment suitably amplifies the central tube size in former cyclone body, two central tubes 4 are set in cyclone body, article two, central tube 4 diameter differences, be positioned at the diameter that inner central tube diameter is less than outside central tube, article two, the structure of central tube 4, material are identical, arranged concentric nests together, and is connected respectively with cyclone inside, and the other end communicates with atmosphere.When the light product of this set is got rid of from cyclone central tube 4, can be divided into two kinds of products that density is different, thereby reach the object of three products sorting.
Operation principle of the present invention:
See Fig. 1, when material and suspension tangentially feed cyclone with certain pressure, liquid stream starts to form along cyclone straight section 7 the external spiral stream of a decline from feeding pipe 3; Near cyclone axle center, form the inside spin stream of one rising; Because centrifugal action forms air column in cyclone axle center; Material can the layering along with the difference of density, and heavy product is discharged from mine tailing outlet 1 under flowing to external spiral.Light product flows to upper with inside spin, discharges because of two central tube diameter differences from overfall, and, intermediate density product can be got rid of from the space between the tube and tube of two central tubes.Thereby selected mineral are divided into three kinds of products, have realized the object of tertiary industry sorting.
