Description

Compound flip flop screen
Technical field
The present invention relates to a kind of compound flip flop screen, belong to material screening technical field, be mainly used in the industries such as coal, mine, sandstone, chemical industry, electric power.
Background technology
The flip flop screen version of prior art is by main sieve basket, float sieve basket, motor driver forms, main sieve basket flexibly connects by shearing block rubber with the sieve basket that floats, fixed cross beam on main sieve basket and the floating crossbeam interlaced arrangement on floating screen frame, and use the sieve plate that elastomeric material makes fixed cross beam and floating crossbeam to be connected, driven the eccentric activator being positioned on main sieve basket by driving device during work, the inertial excitation power that eccentric activator produces makes main sieve basket vibrate, by shearing block rubber, exciting force is transferred to the sieve basket that floats, floating sieve basket is made to do linear reciprocating motion, there is relative displacement poor between main sieve basket and floating sieve basket, fixed cross beam and floating crossbeam correspondingly produce displacement difference, so that sieve plate tension is lax, generation tension and relaxation is moved, by increasing and decreasing the quantity of rubber cutout or adjusting eccentric activator to adjust the amplitude of flip flop screen.The weak point that above-mentioned flip flop screen exists is that screen(ing) machine amplitude according to carrying out doses size variation, and can be difficult to the control respectively to double deck screen levels amplitude.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of compound flip flop screen efficient, reliable, it is applicable to the difficult screening materials carrying classifications such as thin, viscous, wet stock, two working region of upper and lower layer realizing separate unit screen(ing) machine work independently, do not interfere with each other, no matter carry out doses big or little, all show stable amplitude.
Compound flip flop screen of the present invention, including gravity flow screen basket, float sieve basket and lower floor's floating sieve basket on upper strata, float and sieve basket connection upper strata eccentric shaft drive system in upper strata, upper strata eccentric shaft drive system connects upper strata drive motor by Hooks coupling universal coupling, lower floor's floating sieve basket connects lower floor's eccentric shaft drive system, lower floor's eccentric shaft drive system connects lower floor's drive motor by Hooks coupling universal coupling, upper strata is floated between sieve basket and upper strata eccentric shaft drive system, lower floor floats and is respectively provided with X to leaf spring between sieve basket and lower floor's eccentric shaft drive system, X sieves basket to leaf spring with upper strata floating, lower floor floats and connects respectively through sieve basket link between sieve basket, float sieve basket for gravity flow screen basket and upper strata, lower floor floats and is equipped with Z-direction leaf spring and Y-direction leaf spring between sieve basket.
The sieve basket that floats is divided into upper and lower two-layer, and every layer connects eccentric shaft drive system respectively, uses independent drive motor means to be driven during work;After drive motor starts, eccentric shaft drive system rotates and produces center displacement, forcing the sieve basket that floats to do the reciprocating motion of constant amplitude, upper and lower layer eccentric shaft drive system can control amplitude and the rotating speed of upper and lower layer floating sieve basket respectively by the offset of eccentric shaft in eccentric adjustment shaft transmission system respectively and the operating frequency of upper and lower layer drive motor;This structure is without any type of vibrator, amplitude stability, and the direction of motion of the sieve basket that floats is led by Y-direction leaf spring, Z-direction leaf spring and X to leaf spring, to its damping action of having moved.
Described upper and lower layer eccentric shaft drive system all includes the eccentric main axis running through gravity flow screen basket, the two axial ends of eccentric main axis is eccentric segment, a wherein eccentric segment of upper and lower layer eccentric main axis connects upper and lower layer drive motor respectively respectively through Hooks coupling universal coupling, base bearing on eccentric main axis is positioned at main bearing seat, main bearing seat connects gravity flow screen basket, capacity eccentric bearing on eccentric segment is positioned at eccentric bearing block, and eccentric bearing block connects X to leaf spring.Eccentric segment revolves round the sun around eccentric main axis axis, revolution-radius is the centre-to-centre spacing of eccentric main axis axis and eccentric segment axis, eccentric bearing block is connected with upper and lower layer floating sieve basket with sieve basket link respectively by transmission leaf spring, the vertical direction displacement that eccentric bearing block is on business changed the line of production raw, pass to X to swing up and down to leaf spring, horizontal direction be displaced through X to leaf spring pass to each layer sieve basket link do alternating translational, it is achieved float sieve basket tension and relaxation motion.
The invention has the beneficial effects as follows:
Because upper and lower layer motor system does not independently interfere with each other, so each layer can be controlled respectively, it is achieved the bilayer of flip flop screen, double; two drive, double-amplitude, double-frequency rigidity tension and relaxation effect;And no matter feeding coal is big or little, each layer sieve plate all keeps uniform amplitude, and material does " trampoline " motion floating on sieve basket, thus effectively solving stifled sieve, sticking with paste the phenomenons such as sieve, make flip flop screen screening efficiency more stable, reliable, and there is low-maintenance amount, low power consumption and other advantages.
