Operation principle and process:
After drive unit drives box vibrator, be positioned at two box vibrator synchronous vibrations on main screen frame side plate, the fanning strip of box vibrator does linear convergent rate by inner synchromesh gear to same rectilinear direction, to screen(ing) machine straight line exciting force.The exciting force that box vibrator produces passes to main sieve basket, exciting force is passed to by resonant springs the sieve basket that floats by main sieve basket, thus the sieve basket that makes to float does and vibrates, being arranged on float sieve basket on floating crossbeam and fixed cross beam produce " displacement difference ", when fixed cross beam moves floating crossbeam dorsad, sieve plate is tightened up, when floating crossbeam moves towards fixed cross beam, sieve plate is relaxed, material on sieve plate produces " trampoline effect ", raw coal is effectively upspring and disperses, by material dispersion, enter to sieve material coarse granule material and fine granular materials under tension and relaxation motion and produce layering, fine granular materials is easy to sieve near compass screen surface.
Compared with prior art, the beneficial effect that the present invention has is:
1, the present invention is by being directly fixed on box vibrator on side plate, save exciting crossbeam and corresponding erection support etc., decrease consumable accessory, make structure compacter, be convenient to manufacture, install and safeguard, greatly reduce the weight of screen(ing) machine simultaneously, make lower power consumption, energy-conserving and environment-protective, the center of gravity of screen(ing) machine is whole to be moved down, and is conducive to the work of screen(ing) machine.
2, straight line exciting exports, under some specific conditions, obtain circular vibration or long elliptical vibration, change the vibration mode that original banana screen is single, improve screening efficiency, the sieve nest surface texture of multi-angle oblique, makes material be easy to layering and realize consistency of thickness, the treating capacity of effective increasing same model screen(ing) machine, improves 1.2 ~ 1.5 times.
3, application screening with constant bed thickness principle, straight-line oscillation theory, double-mass vibrating principle carry out optimized design, for the industries such as coal, mine, sandstone, chemical industry, electric power provide a kind of efficient, reliable, screening plant with self-cleaning function, be applicable to the difficult screening materials carrying classifications such as thin, sticky, wet stock.
4, can effectively solve in material screening process occur stifled sieve, stick with paste sieve etc. cause screening efficiency low problem, be the effective screening plant of fine moist material dry screening.Especially when handled material is easy to blocking screen cloth, the phenomenon that low power motor solution moist material can be used to unite in screening process, reaches high screening efficiency with relatively little screen area, ensures that screen cloth does not block.
