Description
Technical field
The utility model relates to preparation equipment field, refers more particularly to a kind of large-scale tower spiral concentrator.
Background technology
Spiral mineral is former is that the chute ore dressing differentiation of narrow limit is come, and substantially divides two classes in China; One class is spiral concentrator, has H Han Folai type spiral concentrator abroad, comprises that in the U.S. there is development and application in Canada; There are GL type Φ 600 spiral concentrators in rear Australia, China produces GL-Φ 600(Kang Xin company, a Guangzhou geochemical investigation institute), XL-Φ 750, ML-Φ 7009 (comprehensive preparation equipment), ore deposit, rear development Φ 1100(Xuzhou is large), it is oval linear that their flight sections are generally, and also has certain slope and certain circle compound; Its two class is spiral chute sheet, and common have BL-Φ 1200 spiral chute sheets, dwindles and has Φ 900 to 6000 specifications, amplifies and has Φ 1500, Φ 2000 specifications; Between there being a kind of series of products between them, claim " alternation spiral chute sheet "; But the ore pulp ore dressing stream film of its spiral chute sheet of opinion, according to the introduction of " gravity separation " textbook, first kind spiral mineral stream film need promise number (RE) about 500 left and right, stream film (RE) approximately 300 marginal rotary screw chute lamiflo RE >=300, left and right of Equations of The Second Kind spiral chute sheet, artificial stepless time adjustment control RE=300～200.So the first kind sort suitable granularity 2～0.073mm, Equations of The Second Kind sort suitable granularity 0.25～0.037mm, intermediate sorts suitable granularity 0.125～0.03(0.025) mm.
Mainly there are two kinds of motions in spiral concentrator separator principle flow of slurry on helicoid, one is tangential circulation, and another kind is cross current.Cross current is to be determined by some characteristic of tangential circulation, and because the water velocity on upper strata is fast, tangential flow velocity is large, has compared with large centrifugal force and is pushed to outer rim; The water velocity of lower floor is little, and centrifugal force is little, under Action of Gravity Field, flows to inner edge along horizontal section direction, therefore forms cross current.Cross current has a significant impact sorting, and it can push outer rim to the light mineral gangue that floats over upper strata becomes mine tailing, and the heavy mineral of lower floor can be pushed to inner edge again becomes concentrate simultaneously, thereby improves sorting result; It is firmly different forming characteristic spiral centrifugal masterpiece by flight structural parameters; According to existing investigative technique data and production practices surface, first kind spiral concentrator is for coarse grain mineral aggregate, and disposal ability, in 2～2.5t/h. platform (double end), does not also have larger >=5t/h. platform (double end) at home, and reaching more than ten tphs does not more have; In addition, its incompetent recovery particulate mineral aggregate is born weak point; Equations of The Second Kind spiral chute sheet is for partially thin mineral, common BL-Φ 1200 spiral chute sheet disposal abilities are at 6～6.5t/h. platform (four-head), BL-Φ 1500 production capacity at 13t/h. platform (double end) but its impotentia to process coarse grain 2.5～0.5mm mineral aggregate be also born weak point.

The utility model is realized in the following way:
A kind of large-scale tower spiral concentrator, comprises central shaft tube 1, it is characterized in that: on described central shaft tube 1, be connected with the spiral chute sheet 2 of four; Spiral chute sheet 2 is reducing displacement from top to bottom, and the ratio upper end of its pitch/screw diameter is 0.7, and lower end is the up-narrow and down-wide pyramidal structure of 0.46 formation one; The top of the upper end fixed frame of described central shaft tube 1, the bottom of the lower end fixed frame of central shaft tube 1;
The arrival end of described spiral chute sheet 2 is connected with feed launder 3; The port of export of described spiral chute sheet 2 is connected with mine cut groove 4; Described mine cut groove 4 is " Z " font mounting structure, which is provided with mine tailing blow tank 4.1 and concentrate blow tank 4.2; In described mine cut groove 4, be provided with fan-shaped chute regulating block 5, described fan-shaped chute regulating block 5 is positioned at the top of mine tailing blow tank 4.1 and concentrate blow tank 4.2 the two center;
The sectional curve of described spiral chute sheet 2 is by the sectional curve of bielliptic(al) shape 2.1 and the sectional curve of cubic parabola 2.2 is compound forms.
On the outer wall of described spiral chute sheet 2, be connected with the anti-overflow positive stop strip in edge.
On described mine tailing blow tank 4.1 and concentrate blow tank 4.2, be equipped with discharging opening.
The beneficial effects of the utility model are: bielliptic(al) shape and cubic parabola are composited, and can realize better the separating effect of mineral aggregate; Can adapt to sort the mineral that thickness takes into account and sort, upper limit size reaches 3mm, lower limit granularity 0.04mm or thinner 0.025mm; Spiral is reducing displacement, forms turriform, flow of slurry film on spiral groove face, can bring up a kind of by very fast under the effect that slows down, favourable particulate is strengthened reclaiming; The wave amplitude impact causing because of tide in order to adapt to sea upper hull, design discharging formation four-head is combined into two-way " Z " shape mine cut groove and carries out discharge.
