Technical field
The utility model relates to a kind of ore dressing three products heavy medium cyclone, specifically uses a kind of three products heavy medium cyclone of realizing the high density sorting that low-density heavy-media suspension is realized the non-magnetic sorting mineral of high density.Belong to the sorting technology field.
Background technology
At present, the three products heavy medium cyclone branch that has been widely used in coal is chosen.Wherein, typical example is that Chinese patent application 02158903.8 discloses " a kind of heavy medium cyclone device; coal separation system and coal preparation method ", and this is dense medium coal cleaning process and equipment that a kind of large-scale pressureless fed three-product dense-medium cyclone is a main separation equipment.First section (hereinafter to be referred as one section) feed cylindrical cyclone and second section conical cyclone of (hereinafter to be referred as two sections) cylinder of this kind heavy medium cyclone are composed in series, the mounted angle of one section cylindrical cyclone (central axis and horizontal sextant angle) is 20 °, and the mounted angle of the conical cyclone of two cylindrical sections is 0 °
The used heavy-media suspension density of the above-mentioned three products heavy medium cyclone that adopts in coal production is many below 1.6kg/L, and therefore this three products heavy medium cyclone can not (non magnetic ore of separating density 〉=2.0kg/L) carries out effective sorting to the separating density height.
Sorting for the high non magnetic ore of density in the past sorts with the chemical mineral processing method, and chemical mineral processing has that ore-dressing technique complexity, beneficiation cost height, environmental pollution are serious, products therefrom purifies difficulty or the like shortcoming.Also once tested the employing dense-media process, but not success for various reasons.
Summary of the invention
Technical problem to be solved in the utility model is the defective at above-mentioned prior art, prior art is improved, strengthen the mounted angle of the conical cyclone of a cylindrical section shape cyclone and two cylindrical sections and realize the high density sorting, and then provide a kind of requiring the high non magnetic ore of separating density can carry out the three products heavy medium cyclone of the realization high density sorting of effective sorting.
Solve the problems of the technologies described above by the following technical solutions, a kind of three products heavy medium cyclone of realizing the high density sorting, it is by a cylindrical section shape cyclone of unpressurized feeding and has the conical cyclone of two cylindrical sections of pressing feed to be composed in series.Its structural feature is: the mounted angle of a cylindrical section shape cyclone is between 25 °～50 °, the mounted angle of the conical cyclone of two cylindrical sections is between 5 °～90 °, this cylindrical section shape cyclone front end is provided with heavy-media suspension inlet and mine tailing outlet, and the other end is provided with the raw ore feeding mouth; One end of the conical cyclone of this two cylindrical section is provided with the concentrate outlet, and the other end is provided with the chats outlet.
Owing to adopted technique scheme, compared with prior art, the utility model can carry out sorting to the high density mineral effectively, is specially adapted to the mineral of separating density greater than 2.0kg/L, is a kind of equipment that can realize the gravity separation of high density sorting.The utlity model has that production technology is simple, production cost is low, environmental pollution is little, gained concentrate product grade advantages of higher.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present utility model.
Among the figure, heavy-media suspension inlet 1, one cylindrical section shape cyclone 2, the conical cyclone 4 of raw ore feeding mouth 3, two cylindrical sections, concentrate outlet 5, chats outlet 6, mine tailing outlet 7.
Concrete embodiment
Below in conjunction with the drawings and the specific embodiments the utility model is further described.
The utility model is improvements over the prior art, and its improvements are to have strengthened the mounted angle of the conical cyclone 4 of a cylindrical section shape cyclone 2 and two cylindrical sections.Referring to accompanying drawing 1, the utility model is by the unpressurized feeding cylindrical cyclone, i.e. a cylindrical section shape the cyclone 2 and conical cyclone of the feed of pressure cylinder is arranged, and promptly the conical cyclone 4 of two cylindrical sections is composed in series.The mounted angle of one cylindrical section shape cyclone 2 (central axis and horizontal sextant angle) is between 25 °～50 °, and the setting angle that shows among Fig. 1 is 30 °.The mounted angle (central axis and horizontal sextant angle) of the conical cyclone of two cylindrical sections is between 5 °～90 °, and the setting angle that shows among Fig. 1 is 10 °.Be provided with heavy-media suspension inlet 1 and mine tailing outlet 7 at a cylindrical section shape cyclone 2 front ends, the other end is provided with raw ore feeding mouth 3.One end of the conical cyclone 4 of two cylindrical sections is provided with concentrate outlet 5, and the other end is provided with chats outlet 6.The conical cyclone 4 usefulness pipelines of one cylindrical section shape cyclone 2 and two cylindrical sections are connected in series.
Use this device can obtain concentrate, chats and three kinds of products of mine tailing simultaneously.
During work, to be the 1.8kg/L heavy-media suspension fed with the edge of certain speed by a cylindrical section shape cyclone 2 by heavy-media suspension inlet 1 density, and the phosphorus ore of separating density 〉=2.4kg/L is directly fed by gravity by raw ore feeding mouth 3.Phosphorus ore through conical cyclone 4 sortings of a cylindrical section shape cyclone 2 and two cylindrical sections after, can realize 〉=the high density sorting of 2.4kg/L, the phosphorus ore concentrate product that obtains is discharged by concentrate outlet 5, and phosphorus ore chats product is discharged by chats outlet 6, and the phosphorite tailings product is discharged by mine tailing outlet 7.Concentrate, chats and the mine tailing of the phosphorus ore of discharging carries out the dehydration of product and the recycling of dense media by the method that known dehydration and medium reclaim.Carry out effective sorting for 4 li at the conical cyclone of a cylindrical section shape cyclone 2 and two cylindrical sections, finally obtain concentrate, chats, mine tailing respectively from concentrate mouth 5, mine mouth 6, mine tailing mouth 7 discharge.
Density 〉=the 1.7kg/L of the heavy-media suspension that the utility model adopted, a cylindrical section shape cyclone 2 is determined according to the different of disposal ability with the diameter of the conical cyclone 4 of two cylindrical sections.
