Abstract
A mosaic elastic composite screen plate suitable for sieving of various kinds of vibrating screens comprises a framework, a crossbeam of the framework, a stringer of the framework and elastic sifting bars. The framework is a composite elastic framework formed by adhering polyurethane and 20-g steel plate, a plurality of blind holes are respectively provided on the inner side of the composite elastic framework for supporting the elastic sifting bars, through holes for allowing the elastic sifting bars to pass through are provided on the framework corresponding to the other side of the blind holes and on the crossbeam located at the middle section, and the elastic sifting bars are in clearance fit with through holes where the framework and the crossbeam penetrate. Because the screen plate is an elastic body, the elastic collision effect of the elastic sifting bars can be enhanced during the vibration process of the screen plate along with the screen body to accelerate the loosening and cutting of viscous and moist materials. The oscillation energy produced by the collision and the multi-degree-of-freedom position change of the sifting bars can prevent the screen plate from adhering the materials and being jammed in the cleaning process, thus greatly improving the screening efficiency.
Description
Technical field
The present invention relates to mosaic type elastic compound sieve plate, be particularly useful for the sieve plate of large-scale vibrating screen raw coal dry deep-sizing, also be applicable to the sieve plate of other type bolting.
Background technology
The raw coal dry deep-sizing is an international technical barrier, never is well solved.The flourishing several countries of coal preparation technology released several kinds of relevant devices in the world; China also introduced some the vibratory sieve equipment as piano wire screen, flip flop screen, uniform thickness sieve, banana screen; These equipment all have characteristics separately on sieve plate form and structure, solved some problems under given conditions.But the still version problem that these equipment in use reflect because sieve-plate structure is unreasonable, causes screening efficiency not high, and screen cloth is prone to stop up, and the fault rate height can not satisfy the needs of deep screening operation.Some achievements have been obtained in the exploitation of China to the research of this technical barrier and relevant device in recent years; But the relevant device of being developed can't well solve technological effect and screening efficiency problem, and the various vibratory sieve compass screen surface structure of use and the setting of geometric parameter can't be satisfied raw coal dry deep-sizing needs preferably.
Summary of the invention
The objective of the invention is to overcome the weak point in the prior art, provide a kind of sieve-plate structure reasonable, screening efficiency is high, the not susceptible to plugging mosaic type elastic compound sieve plate of screen cloth.
Mosaic type elastic compound sieve plate of the present invention; Comprise skeleton body; Framework beam, skeleton longeron and elasticity sieve bar, said skeleton body are the composite construction elastomer framework that polyurethane and 20g steel plate gummed form; A side is respectively equipped with a plurality of blind holes of support elastic sieve bar in the composite construction elastomer framework; Be equipped with the through hole that wears elasticity sieve bar on the framework of corresponding blind hole opposite side and the framework beam that is positioned at the middle part, matched in clearance between the through hole that elasticity sieve bar and skeleton body, framework beam wear, the corresponding elasticity of the two side ends face of skeleton body sieve horizontal line position, bar axle center rise to the longitudinal angle a of upper surface be 5～6 °.
The polyurethane composite construction elastomer framework of said skeleton body both sides is provided with and the chimeric groove structure of standard module sieve plate rail chair.
Mosaic type elastic compound sieve plate of the present invention; Adopt the non-bolt connected mode, skeleton body is formed elastomer sieve-plate structure framework with polyurethane and 20g steel plate gummed, and elastomer sieve-plate structure framework and dress elasticity sieve bar within it is under the effect of impact energy; The ability fly-cutting; Bulk material, the oscillation energy that the multiple degrees of freedom collision of the structural elasticity of polyurethane sieve plate combo box support body and elasticity sieve bar is produced makes sieve plate self obtain cleaning, has improved screening efficiency and machine life greatly.In the vibrosieve process, the plane plate that compass screen surface forms an integral body is beneficial to material flowing at compass screen surface.Because sieve plate is from as an elastomer, sieve plate with the vibration processes of sieve nest in the elastic collision effect of enhance elasticity sieve bar, quicken the loose of adhesional wetting materiel and cutting.Oscillation energy that collision produces and the multivariant displacement of sieve bar, the cleaning that makes compass screen surface obtain self is difficult for adhered materials and obstruction, thereby improves screening efficiency greatly.This structure is installed convenient and reliable, and the compass screen surface topology layout is reasonable, adapts to and is used for all types of vibratory sieves, can satisfy the needs of all types of used by oscillating screen in the raw coal dry deep-sizing, has good practicability and application value.

The specific embodiment
Below in conjunction with accompanying drawing an embodiment of the present invention is described further:
Mosaic type elastic compound sieve plate of the present invention mainly is made up of skeleton body 1, framework beam 2, skeleton longeron 3 and elasticity sieve bar 4, and framework beam 2 intersects vertically with skeleton longeron 3 and is separately fixed on skeleton body 1 interior plate, to 1 booster action of skeleton body.Skeleton body 1 usefulness polyurethane and 20g steel plate gummed; Constitute a composite construction elastomer framework; The polyurethane composite construction of composite construction elastomer framework both sides is a groove-like; Directly chimeric with the inserted rail chair that is fixed on the sieve nest spandrel girder, promptly be complementary with the chimeric groove structure of standard module sieve plate rail chair.Composite construction elastomer framework 1 both sides end face, wide at the top and narrow at the bottom, the corresponding elasticity sieve of two side ends face horizontal line position, bar 4 axle center rise to the longitudinal angle a of upper surface be 5～6 °.A side is respectively equipped with a plurality of blind holes of support elastic sieve bar 4 in the composite construction elastomer framework; Be equipped with the through hole that wears elasticity sieve bar 4, matched in clearance between the through hole that elasticity sieve bar 4 and skeleton body 1, framework beam 2 wear on the framework of corresponding blind hole opposite side and the framework beam 2 that is positioned at the middle part.Under the oscillation intensity condition of vibratory sieve; Be used mosaic type elastic compound sieve plate; Utilize the structural elasticity of polyurethane sieve plate combo box support body and the multiple degrees of freedom of elasticity sieve bar to collide the oscillation energy that is produced, realize sieve is passed through in the loose cutting and the acceleration of adhesional wetting materiel.
