Description
Technical field
The present invention relates to vibration screening machinery field, especially standard gauge A seating elastic rod sieve plate, be applicable on the vibratory sieve of various large-scale vibrating screen or screening adhesional wetting materiel.
Background technology
A kind of desirable material sieves under normal circumstances, and its screening efficiency of General Requirements will reach 96%, that is has the granularity of 96% to be less than the particle of regulation screen size by the sieve aperture on compass screen surface.But because vibratory sieve is by the vibration realizing material screening of compass screen surface, following problem is there is: the impact considering the factors such as the rigidity of sieve nest own, intensity in screening process, oscillation intensity generally remains on lower interval (3 ~ 5g), traditional sieve plate just along with sieve nest does rigid motion, itself there is no additional movement, simultaneously again because material humidity that is uneven, material is uneven, these reasons all can affect material fast hierarchical, thoroughly sieve, even cause the problem of windrow and plug-hole, have a strong impact on screening efficiency.So solve because screen cloth oscillation intensity is little and compass screen surface motion mode is single, cause the problem of plug-hole and windrow, be the development of China's coal preparation technique level and the pressing issues of large-scale industrial production always.
Especially for the screening of raw coal in coal washery.Because coal is in recovery process, because the reasons such as coal seam infiltration, the dust-proof water spray in down-hole cause raw coal free moisture more than 7%, add the feature that coal particles is little, specific area large, chance water easily adheres to, be easy to the problem causing plug-hole and windrow, screening effect is deteriorated.Once there is windrow or plug-hole in vibratory sieve in coal washery, the lifting of coal, transport and screening operation all must stop, and this will have a strong impact on transport and the coal separation operation in colliery, cause serious economic loss.
For addressing this problem, Chinese scholars proposes various solution.By improving the oscillation intensity of sieve plate, it proposes very high requirement to the structural strength of sieve nest, causes screening plant production cost too high; Utilize chain or ball cleaning plant, although the cleaning work of compass screen surface can be completed to a certain extent, be easy to cause chain wear to rupture and frequently the dropping of ball dish, cause the danger of shutdown.
Summary of the invention
