Abstract
The utility model relates to a coal dressing series spiral separator which is used for sorting/grading duff and slack with sizes of 3.0-0.07mm and filling gaps of jigging and dense medium dressing coarse and medium grains and slack fraction size dressing in coal slime flotation. The coal dressing series spiral separator comprises spiral grooves, a receiver, a product separated receiving groove, a product shared receiving groove, a coal slurry distributing device and a stand. The coal dressing series spiral separator is formed by a unit comprising 4, 6 or 8 single machines, the section curve of the spiral groove is a special coal dressing curve adapting to demands of washing desulfuration and dust fall of raw coal; each spiral groove comprises five circles which are connected without seams and are seamlessly abutted with a center column, each machine is provided with 2-3 spiral grooves, and thus the occupation production capacity of one machine is increased. The coal dressing series spiral separator has the advantages of simple structure, no moving parts, energy saving, environment friendliness, low production cost, excellent dressing performance and wide application prospect.
Description
Technical field
The utility model relates to the separator field, is specifically related to a kind of coal separation series helix separator, is used for sorting 3.0-0.07 millimeter smalls grade raw coal, desulfurization and deashing output cleaned coal.
Background technology
The raw coal of exploitation can significantly be increased economic efficiency reject the impurity such as sulphur, silicon by washing process after.Lump coal and coarse fraction coal generally sort with jigging and dense media technique.The following coal slime of 200 orders can sort with floatation process.Grade in the middle of both is the effective range of spiral just.
But existing spiral is all the ore dressing spiral, such as being used for sorting molybdenum ore, copper mine, iron ore etc., does not meet the requirement of coal separation.
The utility model content
The purpose of this utility model is to provide a kind of coal separation series helix separator, is used for sorting 3.0-0.07 millimeter smalls grade raw coal, desulfurization and deashing output cleaned coal.
The technical solution of the utility model is as follows:
A kind of coal separation series helix separator comprises the helicla flute that is exclusively used in coal separation, and every helicla flute is conjoined structure, and middle without the fracture one-shot forming, every 2-3 helicla flute is connected in newel and consists of a unit, and receiver is housed unit and the product separation accesses groove; Every 4,6 or 8 units are installed concentratedly in frame and are formed independent unit, described unit integral hoisting, transportation and on-the-spot the installation; Configuration coal slurry distributor and isocon above every unit, below arrange the shared groove that accesses of product; It is characterized in that, the described helicla flute that is exclusively used in coal separation has continually varying groove face and compound cross-section curve, described compound cross-section curve is composited by different curve smoothing connections, larger at material feeding end groove face cross dip, groove face radial rake gradual change subsequently is mild, the exhaust end groove face become milder; Every helicla flute encloses spiral connected the composition by 5, at every circle end, a heavy product offtake is set, and it is live definite by sorting that size is opened and opened to described outlet whether.
Principle of the present utility model and beneficial effect are:
In 4.0-0.05 millimeter grade scope, there are effective density contrast in troilite in raw coal, gangue and coal, when former coal slurry flows through the spiral groove face of ad hoc structure, troilite wherein and gangue can flow to inner ring, cleaned coal flows to the outer ring, and this is because have secondary circulation on groove face.On the helicla flute radial cross-section, the groove face height increases with radius and swells gradually.The centrifugal force that the upper strata coal slurry is produced by spirality circulation becomes to making to the outer ring and flows, and flows to inner ring because of the component that the groove face protuberance obtains to point to the axle center near lower floor's coal of groove face.Under the mystery effect of this " secondary cycle stream ", in coal slurry, the solid material of different densities and granularity carries out " queuing " on radial direction, forms clear minute band, suitably is separated into tail coal, middle coal and cleaned coal in the helicla flute terminal.The utility model is simple in structure, movement-less part, and energy-conserving and environment-protective, production cost is low, sorts function admirable, has a extensive future.
The utility model is exclusively used in coal separation, from ore dressing exist with spiral many different, for this reason and the development specific coal-preparation spiral groove face, be the intensive combination that a rule changes composite curve continuously.Material feeding end groove face cross dip is larger, is beneficial to the coal slurry that just fed to the inner ring dumping tower tray, and groove face radial rake gradual change subsequently is mild, the exhaust end groove face become milder, list the laminar flow band is stable in order to will weigh product (tail coal).Compare with the cubic parabola groove face, slip on groove face thickness and be distributed with a great difference, coal slurry bed of material average thickness increases, the broadening of turbulent flow band thickens, the bed of material that is tending towards the elliptic curve section distributes, and the pitch of adjacent spiral coil is less, and the span ratio is got lower value, to reduce vertical flow velocity, reduce centrifugal forces affect.
Every helicla flute is comprised of 5 circles, at every circle end, a heavy product offtake is set, it is live definite by sorting that size is opened and opened to outlet whether, this special construction, be conducive to adapt to different raw coal character, adapt to the dynamic change of the process that sorts, strengthen and scan function, improve disposal ability, improve sorting result.
Description of drawings
Fig. 1 is the structural representation of coal separation series helix separator of the present utility model.
Wherein, 1-coal slurry distributor, the 2-isocon, the 3-receiver, the 4-helicla flute, the 5-newel, the separation of 6-product accesses groove, the 7-frame, the 8-product shares and accesses groove.
The specific embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
A kind of coal separation series helix separator, comprise the helicla flute 4 that is exclusively used in coal separation, every helicla flute 4 is conjoined structure, and is middle without the fracture one-shot forming, every 2-3 helicla flute 4 is connected in newel 5 and consists of a unit, and receiver 3 is housed unit and the product separation accesses groove 6; Every 4,6 or 8 units are installed concentratedly in frame 7 and are formed independent units, described unit integral hoisting, transportation and on-the-spot the installation; Configuration coal slurry distributor 1 and isocon 2 above every unit, below arrange the shared groove 8 that accesses of product; The described helicla flute 4 that is exclusively used in coal separation has continually varying groove face and compound cross-section curve, described compound cross-section curve is composited by different curve smoothing connections, larger at material feeding end groove face cross dip, groove face radial rake gradual change subsequently is mild, the exhaust end groove face become milder; Every helicla flute encloses spiral connected the composition by 5, at every circle end, a heavy product offtake is set, and it is live definite by sorting that size is opened and opened to described outlet whether.
