Summary of the invention
The technical problem that the utility model solves is to provide a kind of two product dense medium cyclone utilizing low-density suspension to realize the effective sorting of high density mineral when feeding pressure is low.
To achieve these goals, the utility model is to provide a kind of low pressure feed two product dense medium cyclone realizing the sorting of low-density medium high density, this dense medium cyclone is divided into concentration stage and sorting level, comprise the cylindrical shape primary concentration cyclone and the conical secondary cyclone separator of cylinder round platform that are connected by pipeline, one section adopts low pressure feed, mainly realize the concentrated of low-density medium, two sections is utilize concentrated rear media implementation high density sorting.In order to realize the highly enriched degree of one section of cyclone low-density medium under low pressure feed, and ensureing two sections of cyclone sortings under high density, primary concentration cyclone to be barrel diameter with the largest particles diameter ratio be 8-12, one section of feed pipe diameter be 0.3-0.4 with the ratio of drum diameter, bore than being the stepless adjustable pressurized feeding cyclone of 1.6-2.4 and section of overflow pipe insertion depth; Secondary cyclone separator is the conical cyclone of cylinder round platform, round platform part cone angle is 5 °-20 °, tapered segment cone angle be 40 °-90 ° and two sections of overflow pipe insertion depths stepless adjustable; Primary concentration cyclone one end is provided with feed entrance and the outlet of concentrated overflow suspension, secondary cyclone separator one end is provided with low density products outlet, the other end is high density product outlet, the feed pipe of primary concentration cyclone and secondary cyclone separator is evolvent type feed pipe, and setting angle is 20 °-30 °.
Described two product dense medium cyclone are when carrying out high density sorting mineral, and the overflow of primary concentration cyclone is qualified suspension, returns qualified medium cylinder; The overflow of secondary cyclone separator and underflow produce concentrate and tailings two product respectively, are exported and high density product outlet discharge by low density products.
Described two product dense medium cyclone are when carrying out high density sorting mineral, when the suspension of certain density and the mixture of raw material are fed with certain pressure by feed entrance, after the concentrated of one-level cyclone with the sorting of second cyclone, the difference of separating density and density of suspending liquid can reach 0.6-1.0kg/l.
The described primary concentration cyclone of two product dense medium cyclone and the diameter of secondary cyclone separator are determined according to the difference of the maximum particle diameter for the treatment of material and disposal ability, one-level cyclone is on the basis of conventional cyclone, reduce barrel diameter, under the prerequisite that second cyclone feeding pressure is more than needed, the feeding pressure of one-level cyclone can be reduced; Adopt major diameter feed pipe, strengthen concentrated effect, improve the density of suspending liquid entering second cyclone; Meanwhile, one-level cyclone mainly plays inspissation, only has a small amount of suspension to enter overflow, entering second cyclone smoothly, on the basis of conventional cyclone, greatly improving cone ratio for ensureing to enter the more than needed and concentrated material of second cyclone feeding pressure; Further, second cyclone adopts cylinder round platform conical design and tapered segment to adopt large cone angle design, both can increase the separating density of second cyclone, can reduce second cyclone internal turbulence again, be conducive to the raising of the efficiency of separation.
The one-level cyclone of described two product dense medium cyclone and second cyclone adopt evolvent type feed pipe feed, can reduce feed turbulent flow, reduce the pressure loss.Meanwhile, increase the setting angle of firsts and seconds cyclone, be conducive to large density product and enter underflow and reduce excess flow, and then reduce the feeding pressure of one-level cyclone.
Described two product dense medium cyclone can be used for the three products sorting of low-density level product content few (mass yield is less than 20%) in raw ore density composition, low density products is produced in the overflow of one-level cyclone, and second cyclone overflow and underflow produce Midst density product and high density product respectively.
Beneficial effect: compared with prior art, the utility model is little by barrel diameter, feed pipe diameter large, bore than large cylindrical shape primary concentration cyclone, and tapered segment adopts the conical secondary cyclone separator of the cylinder round platform of large cone angle design, be conducive to the feeding pressure reducing one-level cyclone, improve the separating density of second cyclone and reduce the turbulence level of second cyclone; Firsts and seconds cyclone all adopts evolvent type feed pipe, is conducive to reducing the pressure loss, reduces the pressure needed for pan feeding; Above-mentioned improvement can ensure to utilize the effective sorting of low-density suspension realization to high density mineral when feeding pressure is low, feeding pressure reduces 10%-40% compared to conventional cyclone, the difference of separating density and density of suspending liquid can reach 0.6-1.0kg/l, and this two products dense medium cyclone production technology is simple, energy consumption is little, equipment and pipe wear is little, production cost is low, the efficiency of separation is high.
