Abstract
The invention discloses a double-medium unpressurized feeding cyclone for high-density separation and belongs to separation equipment for mining. The cyclone comprises a primary truncated cone-shaped cyclone and a secondary cylindrical conical cyclone which communicate with each other by pipelines. Cone angle of the primary cyclone is 5-20 degrees and cone angle of the cone section of the secondary cyclone is 30-180 degrees. One end of the primary cyclone is provided with a large medium inlet, a small medium inlet and a concentrate outlet; and the other end is equipped with a raw ore inlet. A cone end of the secondary cyclone is provided with a tailing outlet and the lower section of the secondary cyclone is provided with a middling outlet. By the adoption of the double-medium unpressurized feeding cyclone provided by the invention, high-density mineral is effectively separated, medium inlet pressure is reduced, and uniformity of a flow field in the cyclone is improved. The heavy medium cyclone has advantages of simple production technology, low cost, little environmental pollution and high grade of obtained concentrate product.
Description
Technical field
The present invention relates to a kind of mining screening installation, specifically a kind of two Jie's unpressurized feeding cyclones of giving of 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.Existing cyclone exists little dynamics ore deposit separating effect not enough; The problem that clean coal recovery is low; The big problem of follow-up flotation operation intensity; And the used heavy-media suspension density of existing three products heavy medium cyclone is many below 1.8kg/L, and the non magnetic ore higher to separating density can't carry out effective sorting, influences the efficiency of separation and quality.And the single mouth of going into to be situated between can't effectively be regulated and controlled the different raw coal of germplasm, and the big mouth of going into to be situated between may cause cash content higher, influences separating effect.
Summary of the invention
Goal of the invention: the technical problem that the present invention will solve provides a kind of two Jie's unpressurized feeding cyclones of giving that improve the efficiency of separation and effect and be applicable to the high density sorting.
Technical scheme: to achieve these goals; Two Jie's unpressurized feeding cyclones of giving of a kind of high density sorting of the present invention comprise truncated cone-shaped one-level cyclone and the conical second cyclone of cylinder with the pipeline connection; The cone angle of one-level cyclone is 5 °～20 °; The cone angle of second cyclone tapered segment is 30 °～180 °, and an end of one-level cyclone is provided with the mouth of going into to be situated between greatly, goes into Jie's mouth and concentrate outlet for a short time, and the other end is provided with the raw ore inlet; The tapering point of second cyclone is provided with mine tailing outlet, is provided with the chats outlet below the second cyclone.Wherein, go into Jie's mouth and mouthful both sides up and down that lay respectively at one-level cyclone end of going into to be situated between for a short time greatly.
Said cyclone is when carrying out the sorting of high density non magnetic ore; Heavy-media suspension can be fed with certain speed with the mouth of going into to be situated between for a short time by the mouth of going into to be situated between greatly respectively, and the non magnetic ore of high density is fed by gravity by the raw ore inlet, after the sorting of process 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, and 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.
Beneficial effect: compared with prior art; The present invention not only adopts the conical design of one-level cyclone, the big cone angle design of second cyclone; Thereby the separating density that has increased second cyclone is carried out sorting to the high density mineral effectively; Also add two designs that are situated between of giving, effectively reduced the pressure and improved the uniformity of cyclone interior flow field of going into to be situated between, can reduce the possibility that cash content raises.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, the three products heavy medium cyclone of realization high density of the present invention sorting 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 °; The both sides up and down of one end of one-level cyclone 1 are respectively equipped with goes into to be situated between the mouth 3 and the mouth 4 of going into to be situated between for a short time greatly, is provided with concentrate outlet 5 in the port, and the other end of one-level cyclone 1 is provided with raw ore feeding mouth 5; One end of second cyclone 2 is provided with mine tailing outlet 7, is provided with chats outlet 8 below the second cyclone 2.The mounted angle of one-level cyclone 1 is at 30 °, 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.
