Description
Technical field
The invention belongs to vibration screening machinery fields, are directed primarily to two Uniaxle excitation sources and are arranged on flip flop screen compass screen surface
The exciting force on lower both sides is oriented parallel to the flip flop screen of compass screen surface.
Background technique
Flip flop screen be for sieving rubbish or adhesional wetting materiel, by the movement of tension and relaxation compass screen surface relaxation by materials casting,
It falls, realizes the screening to adhesional wetting materiel.Existing flip flop screen, the motion profile of vibration excitor are uniaxial Circular test or Biaxial linear
Track.Since the exciting force resultant force that vibration excitor generates is not parallel with the compass screen surface of flip flop screen, make to act on effective on tension and relaxation compass screen surface
It stretches pulling force to become smaller, compass screen surface discontinuity, the amplitude of compass screen surface tension and relaxation vibration reduces；The slinging force for causing material to obtain is small, causes
Material plug-hole, screening percentage reduce.
Summary of the invention
The object of the present invention is to provide the flip flop screen that a kind of exciting force is oriented parallel to compass screen surface, two single shafts of the flip flop screen
The both sides up and down of flip flop screen compass screen surface are arranged in exciting source, and the exciting force of exciting source is oriented parallel to compass screen surface；Keep the stress of compass screen surface equal
It is even, slinging force is big, solve the problems, such as that material plug-hole and screening percentage are low.
The present invention is achieved by the following technical solutions, including screen frame, fixed cross beam, floating crossbeam, Relaxation sieve-plate, swash
Vibration source and vibration damping support device；The both ends of fixed cross beam are directly installed on the side plate of screen frame by fastener, floating crossbeam
Both ends are mounted on the side plate of screen frame by secondary damping rubber block；Relaxation sieve-plate be mounted on fixed cross beam and floating crossbeam it
Between, compass screen surface is formed, it is characterized in that：At the intermediate position of screen frame longitudinal direction, there are two independent Uniaxle excitation source, two independent lists
Axis exciting source is separately positioned on the upper and lower both sides of tension and relaxation compass screen surface；The shaft center line in two Uniaxle excitation sources is parallel to each other, place
Plane perpendicular to tension and relaxation compass screen surface；The direction of rotation in two Uniaxle excitation sources is on the contrary, the position for generating exciting force resultant force passes through
The center of gravity of screen(ing) machine ginseng vibration body.
The tension and relaxation compass screen surface is formed by 1-3 layers, and the Relaxation sieve-plate of every layer of compass screen surface is mounted on crossbeam, Relaxation sieve-plate
Side is mounted on fixed cross beam, and the other side is mounted on floating crossbeam, forms whole tension and relaxation compass screen surface.
When flip flop screen works, two Uniaxle excitation sources generate the exciting force for being parallel to compass screen surface, in driving screen frame straight-line oscillation
While, so that floating crossbeam is made straight reciprocating motion under the action of vibrating inertia force and secondary damping rubber block.Floating crossbeam
The Relaxation sieve-plate for driving its two sides, forms stretched and relaxed tension and relaxation movement, carries out tension and relaxation to the material on compass screen surface, casts and sieve.
The invention has the advantages that flip flop screen of the invention, the exciting force resultant force that two Uniaxle excitation sources generate is parallel
In tension and relaxation compass screen surface, makes to act on and effectively stretch that pulling force is big, and compass screen surface uniform force, compass screen surface Oscillation Amplitude is big, and material obtains on tension and relaxation compass screen surface
The slinging force obtained is big, and when sieving adhesional wetting materiel, plug-hole, screening percentage be not high for compass screen surface.Since vibrator is arranged in the middle part of screen frame
Position, keeps screen frame compact-sized, and the support spring decrement of stress equalization, front and back end vibration damping support device is consistent, and screen(ing) machine operation is flat
It is steady reliable.Suitable for sieving rubbish and the more various adhesional wetting materiels of water content.
