Description
Technical field
The invention belongs to processing equipment field, mine, be a kind of for carrying out classification, the continuous grading of adjustment grain diameter, removing clay powder content to artificial sand simultaneously, produce the plant equipment meeting national standard building sand.Also can be used for other metal, nonmetallic ore have same product standard require production technical field.
Background technology
Existing typical conventional artificial sand production equipment has the technology such as vibratory sieve, air sieve, shedding, washing equipment, still there is produced artificial sand grain composition and do not reach building sand standard in the application of these equipment and technologies at present, the particle of 150 ~ 30 μm, 300 ~ 600 μm sections is not enough, grain composition is poor, mud powder (or stone flour) content is large, quality of production fluctuation is large, so make concrete, build by laying bricks or stones, preparation, the production of motar and adopt the application of modern additive technology to be restricted:
Vibratory sieve technology: sieve number is excessive, very easily blocks mesh, forms the accumulation of artificial layer of sand and causes damp production; Sieve number is too small, and in sand, the sand of grain diameter 80 ∽ 300 μm of parts can not get retaining, and forms the out of stock of the continuous grading of sand;
Air sieve technology: quality of production control procedure depends on density, the moisture content of artificial sand, when density, moisture content one timing of artificial sand, the quality of the artificial sand produced is relatively just stable; Otherwise the quality of artificial sand is just unstable;
Shedding technology: production process, to slough the powder containing quantity in sand, can not be sieved the grain diameter of sand, more can not adjust the grain composition of sand;
Washing equipment technology: mud powder is washed off by sand washer by artificial sand, in sand, the particle of part 150 ~ 300 μm is as easy as rolling off a log washed away, and quality can not be guaranteed, and is that the discharge of water source restriction and mine tailing causes environmental pollution in addition.
The present invention integrates the structure of screen cloth, air sieve, has and overcomes vibratory sieve, air sieve, the deficiency of powder remover in produced production assurance, effectively can retain the amounts of particles of artificial sand 150 ~ 300 μm, 300 ~ 600 μm section particle diameters.Supporting with existing artificial sand production line; can optimized device dispensing unit; simplification of flowsheet; realize the production modernization operation of artificial sand; and effectively can reduce the production cost of artificial sand, improve sand efficiency processed, ensure artificial chiltern amount; be beneficial to environmental protection, realize the remarkable result of carrying out production strictly in line with rules and regulations.
Summary of the invention
The object of invention, the object of invention overcomes the said equipment in artificial sand production process, the particle continuous grading of the artificial sand existed is out of stock, mud powder (or stone flour) content large, compass screen surface is easy to accumulation, the problem of blocking, provides a kind of combined type screening machine be based upon on vibratory sieve, air sieve technical foundation.
Object of the present invention adopts following design to realize:
A kind of combined type screening machine, comprises screen box, air inlet, feed hopper, screen cloth, discharge gate; The present invention is characterised in that, air inlet is opened in screen box top, between air inlet and screen box, be provided with air distribution plate; Feed hopper is located at screen box top, below feed hopper, be set to feed conduit; Spiral distributor is provided with between feed hopper and feed conduit; Screen cloth upper end is fixed on screen box inwall and is hinged and connected on rear side of feed conduit, and screen cloth lower end and an arc material baffle upper end are hinged; Arc material baffle lower end is stretched between the roller that a pair is fixed on screen box inwall; Be hinged at the screen cloth back side and be connected to electric pushrod; Stock guide is provided with at screen cloth epimere.
The present invention is provided with air outlet in described screen box upper back, be respectively equipped with bottom described screen box with the discharge gate A of plane orthogonal, with the discharge gate B of vertical line with an inclination alpha, wherein the inclination alpha of discharge gate B can be held to be formed and meet the clog-free space of movement locus, arc material baffle lower end.
Spiral distributor of the present invention is for be provided with two along same axis; The end of described spiral distributor tail is arranged on the support of bearing jointly; The uniform rectangular mouth offered in double-edged fine-toothed comb shape on the housing of described spiral distributor bottom.
The angle β of screen cloth of the present invention and horizontal plane is set to 45 ~ 75 °, adopts the stroke of electric pushrod, by top, draws for regulating realization.
The present invention compared with prior art has following effect:
(1) the present invention adopts screen cloth to install in 45 ~ 75 ° of angular ranges, the screen cloth of certain order number passes through the angle α of adjustable screen face and horizontal plane, the effect that can form sieve number generation is several times even change of tens times, is particularly suitable for the artificial sand of Cut size in 0.15 ~ 2.36mm section.Compared with existing vibrating screen mesh, the order number of screen cloth can reduce further, and the wire diameter of woven screen can increase further.Meanwhile, come from the air-flow cutting screen cloth of air inlet, sieve screen apertures not easily blocks, and overcomes traditional shaker and often blocking occurs because mesh is little and install the phenomenon of clearing up hammer and carrying out beaing, improve screen cloth reliability and durability.
(2) present invention employs air and select powder technology, when artificial sand by stock guide be waterfall shape sieve along compass screen surface time, the mud powder be mixed in artificial sand all is constantly disperseed out by each diagrid hole, the air-flow of air inlet passes through the adjustment of air distribution plate air quantity, blow to by mud (or stone) powder disperseing out equably, now air-flow is carry mud (or stone) powder and is discharged by air outlet.Compared with existing same category of device, vibratory sieve does not possess this function; Air sieve, owing to being carry out classification by the density of artificial sand by air-flow, is usually subject to the density of sand, the impact of humidity, and the phenomenon of mixed level, batch mixing happens occasionally.In sum, professional, the adjustable of its function are sieved more convenient than air, and reliability is stronger.
(3) the present invention adopts spiral distributing device cloth, enter the artificial sand of spiral distributor, respectively under the outside helical blade effect of two thrust, leave center continuously along axis outwards movement, be scattering on stock guide through the uniform double-edged fine-toothed comb having Lou material of screw lower case, again artificial sand is spread further along compass screen surface direction by stock guide, thus form the continual waterfall shape bed of material, be beneficial to screening and the selection by winnowing of artificial sand.Compare with existing dither bulk material device, have the advantages that structure is simple, cloth constant homogeneous, convenient operating maintenance, failure rate is low, reliability are high.
(4) the present invention adopts interlock arc material baffle device, and arc material baffle device can play compartment effect effectively, and action is simple, reliable, does not affect the work of discharge.Existing equipment is without this device.
(5) the present invention integrates screening and air selects powder, sieve sand effect with select powder effect to unite two into one, when supporting the use with sand production line processed, can the configuration of effective optimized device, the interface of the conveying mechanism between minimizing unit and apparatus and process.Compare with existing sand production line processed, be namely conducive to optimized production process flow process, simplified apparatus dispensing unit, reduce equipment investment, improve production efficiency, turn reduce the floor space of sand production line processed, reasonably utilize space, place, be convenient to apparatus arrangement and maintenance.
