Abstract
The invention discloses an unpressurized feeding three-product dense medium cyclone for high-density separation and belongs to the technical field of sorting equipment. The dense medium cyclone comprises a primary truncated cone-shaped cyclone and a secondary cylindric-conoid cyclone which communicate with each other through pipelines. The cone angle of the primary cyclone is 5-20 degrees and the cone angle of the cone part of the secondary cyclone is 30-180 degrees. One end of the primary cyclone is provided with a low-density heavy medium fluid suspension inlet and a concentrate outlet, and the other end is provided with a raw ore inlet. One end of the secondary cyclone is provided with a mine tailing outlet and the lower portion of the secondary cyclone is provided with a middling outlet. The unpressurized feeding three-product dense medium cyclone provided by the invention can be used to effectively sort high-density minerals and is especially suitable for sorting of minerals with the density being greater than 2.4 kg/L. The dense medium cyclone has advantages of simple production technology, low cost, little environmental pollution and high grade of obtained concentrate products.
Description
Technical field
The present invention relates to a kind of mining screening installation, specifically a kind of pressureless fed three-product dense-medium cyclone of realizing the high density sorting.
Background technology
Current; At home and abroad the three products heavy medium cyclone branch that has been widely used in coal industry is chosen; Three products heavy medium cyclone utilizes centrifugal force to make feed coal not only obtain effective sorting, the cleaned coal that output quality is qualified, and low-density suspension concentrated; Further improve density of suspending liquid to realize that secondary selects again, coal and two kinds of products of spoil in finally sub-electing.The used heavy-media suspension density of existing three products heavy medium cyclone is many below 1.8kg/L, and therefore this three products heavy medium cyclone can not carry out effective sorting to the higher non magnetic ore of separating density, influences the efficiency of separation and quality.
Summary of the invention
Goal of the invention: the technical problem that the present invention will solve provides a kind of pressureless fed three-product dense-medium cyclone that can carry out effective sorting to the high non magnetic ore of separating density.
Technical scheme: to achieve these goals; A kind of pressureless fed three-product dense-medium cyclone of realizing the high density sorting of the present invention; Comprise the truncated cone-shaped one-level cyclone and the conical second cyclone of cylinder that are communicated with pipeline; The cone angle of said one-level cyclone is 5 °～20 °, and the cone angle of said second cyclone tapered segment is 30 °～180 °, and one-level cyclone and second cyclone are unpressurized feeding type cyclone.
One end of said one-level cyclone is provided with low-density heavy-media suspension inlet, concentrate outlet, and the other end is provided with the raw ore inlet; One end of second cyclone is provided with mine tailing outlet, is provided with the chats outlet below the second cyclone.Wherein, the mounted angle of said one-level cyclone is at 30 °～60 °, and the second cyclone level is installed.
Said three products heavy medium cyclone is when carrying out the sorting of high density non magnetic ore; Density is that the heavy-media suspension of 1.8kg/L～2.4kg/L is fed with certain speed by the heavy-media suspension inlet; The non magnetic ore of high density is fed by gravity by the raw ore inlet; After the sorting through one-level cyclone and second cyclone, can realize the high density sorting of 2.4kg/L～3.2kg/L, the concentrate product that obtains is discharged by the concentrate outlet; Middle mineral products are discharged by the chats outlet, and product from failing is discharged by the mine tailing outlet.Concentrate, chats and the mine tailing of discharging is for recycling and reuse through the method that dehydration and medium reclaim.
Said three products heavy medium cyclone is when carrying out the sorting of high density non magnetic ore, and the density of the heavy-media suspension of employing can realize the separating density of 2.4kg/L～3.2kg/L at 1.8kg/L～2.4kg/L.The diameter of one-level cyclone and second cyclone is confirmed according to the different of disposal ability.
Beneficial effect: compared with prior art, the present invention is through having the one-level cyclone of certain cone angle truncated cone-shaped structure, and adopts the auger corner structure; Increased the separating density of second cyclone, can carry out sorting to the high density mineral effectively, be specially adapted to the mineral of separating density greater than 2.4kg/L; Because material is under passive state, directly to feed the cyclone that heavily is situated between; The selected raw coal size upper limit is not limited by the channel size of pump, and feed coal is without the pump strong agitation, so the feed particle size upper limit is big; Reduced pump crossing of material pulverized, the secondary slime amount is less.This heavy medium cyclone production technology is simple, cost is lower, environmental pollution is little, and it is high to obtain the concentrate product grade.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is done explanation further.
As shown in Figure 1, realization high density sorting pressureless fed three-product dense-medium cyclone of the present invention is connected with pressure feed one-level cyclone 1 and the feed of pressure second cyclone 2 is arranged through pipeline.The cone angle of one-level cyclone 1 is 5 °～20 °; Second cyclone 2 tapered segments adopt big cone angle design; Cone angle is 30 °～180 °, and an end of one-level cyclone 1 is provided with low-density heavy-media suspension inlet 3, concentrate outlet 4, and the other end is provided with raw ore inlet 5; One end of second cyclone 2 is provided with mine tailing outlet 6, is provided with chats outlet 7 below the second cyclone 2.The mounted angle of one-level cyclone 1 is at 30 °～60 °, and second cyclone 2 levels are installed.
The above only is a preferred implementation of the present invention; Be noted that for those skilled in the art; Under the prerequisite that does not break away from the principle of the invention, can also make some improvement and retouching, these improvement and retouching also should be regarded as protection scope of the present invention.
