Description
Technical field:
What the present invention relates to is the screening plant that a kind of industry is used to sieve material, especially a kind of special screening separating device for sintered materials.
Background technology:
In the prior art, technique known is the sintering feed uniform thickness sieve in usefulness, this uniform thickness sieve has the shock absorber on support and the support, the casing of band charging aperture, oversize outlet and screening outlet is installed on shock absorber, vibration source also is housed on casing, be made up of screen cloth in casing, its screen cloth is the screen cloth that adopts the fixedly sieve aperture of three sections or two sections different angles, can carry out screening with constant bed thickness to sintering feed.But, because screen cloth uses is the fixing screen cloth of sieve aperture, fixedly sieve aperture is stifled with regard to causing sieve aperture to be sized material critical particle card easily, and fixedly its percent opening of the screen cloth of sieve aperture is low, and the percent opening of screen cloth is low, just make screening efficiency low, stifled for reducing the screening material to the card of sieve aperture, improve screening efficiency, just must strengthen the oscillation intensity of casing, in order to increase the quantity of sieve aperture, just must strengthen screen area.This makes again, and the volume of casing increases, weight increases, and has more increased the consumption of power, and this structure also is not easy to dustproof the processing, and this is the existing in prior technology weak point.
Summary of the invention:
The present invention is exactly at the existing in prior technology deficiency, and provide a kind of special screening separating device for sintered materials technical scheme, what the screen cloth of this scheme adopted is several different Cantilevered screens of compass screen surface angle, the sieve aperture of Cantilevered screen is the sieve aperture of the unlimited variation of front end, when the screening material, be not prone to the stifled phenomenon of card of screening material, and the percent opening height of Cantilevered screen, so just can reduce cover surface, and then having reduced the weight of sieve nest, the power that vibration source needs is just little.And can improve reliability and screening efficiency in the screening process, can reach screening with constant bed thickness equally, the processing of also preventing dust easily.
This programme is realized by following technical measures: comprise the shock absorber on support and the support, the casing of band charging aperture, oversize outlet and screening outlet is installed on shock absorber, vibration source also is housed on casing, also have screen cloth in casing, the characteristics of this programme are that described screen cloth is made up of at least two Cantilevered screens; Feed inlet end in casing has drapery panel, in oversize outlet and screening outlet end reclaiming plate is arranged; Between described drapery panel and reclaiming plate, described Cantilevered screen is arranged to low dip by height, and the compass screen surface of high-end Cantilevered screen and the angle of horizontal plane are greater than the compass screen surface of low side Cantilevered screen and the angle of horizontal plane; The compass screen surface of the most significant end Cantilevered screen adjacent and the angle a angle of horizontal plane with drapery panel, a angle is less than miter angle; The compass screen surface of the least significant end Cantilevered screen adjacent with reclaiming plate and the angle b angle of horizontal plane, b angle are greater than 3 degree angles.The concrete characteristics of this programme also have, and described Cantilevered screen is the individual layer Cantilevered screen.Described Cantilevered screen is double-deck Cantilevered screen.Described Cantilevered screen is the multilayer Cantilevered screen.The Cantilevered screen quantity that the compass screen surface of described Cantilevered screen is identical with horizontal plane angle is less than or equals 20.Described vibration source makes the bin movement track of casing vibration for oval.Described vibration source makes the bin movement track of casing vibration for circular.It is straight line that described vibration source makes the bin movement track of casing vibration.
The beneficial effect of this programme can be learnt according to the narration to such scheme, because in this scheme, used screen cloth is made up of at least two Cantilevered screens.Feed inlet end in casing has drapery panel, in oversize outlet and screening outlet end reclaiming plate is arranged.Cantilevered screen between described drapery panel and reclaiming plate is arranged to low dip by height, and the compass screen surface of high-end Cantilevered screen and the angle of horizontal plane are greater than the compass screen surface of low side Cantilevered screen and the angle of horizontal plane.The compass screen surface of the most significant end Cantilevered screen adjacent with drapery panel and the angle a angle of horizontal plane, a angle is less than miter angle.The compass screen surface of the least significant end Cantilevered screen adjacent with reclaiming plate and the angle b angle of horizontal plane, b angle are greater than 3 degree angles.This structure, because what adopt is Cantilevered screen, then by the fixing compass screen surface formed of the unsettled a plurality of gratings of the other end of a rule one end, so its characteristics are exactly the percent opening height, compass screen surface is shorter for Cantilevered screen, and has secondary vibration and can make the sieve aperture variation.By several oblique arrangement up and down, the Cantilevered screen that the compass screen surface angle is different can be realized screening with constant bed thickness, and the angle of each compass screen surface is to be determined by granularity that is sized material and the shared ratio of minus mesh.Because Cantilevered screen has the sieve aperture that secondary vibration changes, stifled with regard to make that the material that is sized is not easy the sieve aperture card in screening process, so just do not need the brute force vibration of vibration source, reduced power consumption, and to adapt to movement locus that vibration source makes the casing vibration be oval, circle or straight line.The percent opening height of Cantilevered screen, transformable sieve aperture and short compass screen surface, that just the volume of casing can be done is less, casing is little, the weight of casing is corresponding just light, also saved the energy consumption of vibration source, and can reduce the used floor space of screening plant, in addition, the volume of casing is little also takes dust prevention easily.This shows that the present invention compared with prior art has outstanding substantive distinguishing features and obvious improvement, the beneficial effect of its enforcement also is conspicuous.
