The invention belongs to self-synchronous vibration machinery fields, disclose a kind of multimachine driving circular motion vibro-crusher, including endoplast and ectoplast, shock-absorbing spring, two vibration excitors.Using self synchronization theory, two vibration excitors are symmetrically arranged in endoplast, and big distance installation.Two eccentric rotors operate synchronously when work and their phase difference can be stablized near 0 °, drive endoplast to realize that revolution at a high speed moves in ectoplast cavity with this, and the synchronous driving of two-shipper can be realized very big reduction ratio and oscillation intensity.The present invention combines double vibration excitor self synchronization theories, realizes the innovation of a new-type vibrating crusher.Crusher is suitable for the clinker of broken superhard alloy ore (such as evanohm ore) and steel mill.
Description
Technical field
The invention belongs to self-synchronous vibration machinery fields, are related to a kind of multimachine driving circular motion vibro-crusher.
Background technique
Crusher appears in the former Soviet Union earliest, since first generation unit for inertial conic crusher, utilizes vibration force broken material
Development ceaselessly carrying out always, successfully have developed jaw crusher, circular cone inertia crusher, kibbler roll and impact
Formula crusher.
By taking kibbler roll as an example, kibbler roll utilizes the cylindrical roller of 2 rotations, and ore is made to be squeezed and grind
The effect cut is broken, is then discharged between two rollers when ore reaches granularity requirements.By roller number, kibbler roll is divided into list
Three roller of roller, double roller and double sections, double sections 4 kinds of four-roller.According to roll surface shape, it is divided into two kinds of plain roller machine and flank of tooth roller machine.Roll-type is broken
Broken machine has that structure is simple, compact, light, reliable operation, adjustment reduction ratio is convenient, it is broken etc. excellent to carry out to water-containing materials
Point.
Conventional roller-type crusher main structure is between two rollers equipped with wedge shape or gasket regulating device, the top of Wedge device
End is equipped with adjustment bolt, and when voussoir is pulled upwardly by adjustment bolt, movable roller is lifted off fast pulley by voussoir, i.e. between two rollers
Gap becomes larger, and discharging-material size becomes larger, and when voussoir is downward, movable roller two-wheeled gap under the action of holddown spring becomes smaller, discharging
Granularity becomes smaller.Gasket device is to adjust discharging-material size size by the quantity or thickness of increase and decrease gasket, when increasing gasket
Two roller gaps become larger, and when reducing gasket, two roller gaps become smaller, and discharging-material size becomes smaller.
The reduction ratio of common crusher is small, and product grading is big, and broken requirement is not achieved, and broken low output, energy consumption is high,
Material easily adheres to, to reduce crusher service life.
Summary of the invention
In order to overcome the shortcomings in the prior art, the invention proposes a kind of multimachines to drive circular motion vibro-crusher,
Including two schemes:
The first scheme: the kinetic model of the vibro-crusher includes endoplast, ectoplast, shock-absorbing spring, vibration excitor；
Wherein, mass center central symmetry of two vibration excitors relative to endoplast, is installed in endoplast and constitutes rolling element, is located at ectoplast
In cavity；Each vibration excitor is made of the eccentric rotor that an alternating current generator drives respectively；The big distance installation of two vibration excitors, together
To revolution, i.e., the half of two vibration excitor revolution axle center lines is greater than the endoplast radius of gyrationTimes；Two vibration excitors it is inclined
The stable phase potential difference of heart rotor is 0, that is, is rotated synchronously, and drives endoplast to transport along ectoplast cavity inner wall circumgyration with this
It is dynamic, reach and material in the gap between cavity inner wall and endoplast is crushed.
Second scheme: on the basis of the first scheme, further include other two vibration excitor, be symmetrically arranged on ectoplast
Left and right ends are turned round in the same direction, relative to the mass center central symmetry of ectoplast, and big distance installation, i.e. two vibration excitor revolution axle centers
The half of line is greater than the ectoplast radius of gyrationTimes；Vibration excitor on inside and outside plastid turns on the contrary, on the same plastid
Two vibration excitors phase difference be 0 °, realize the antiphase circular motion of two plastids.
Further, the shock-absorbing spring has four groups, is separately mounted to ectoplast four direction up and down, and connection is outer
Plastid and basis.
Beneficial effects of the present invention:
Reduction ratio can be improved using dither effect, and the smashing principle that dither effect reaches can be crushed superhard alloy mine
Stone, such as the clinker of evanohm ore, steel mill.
For above-mentioned some superhard matter ores or iron ore it is broken when, conventional crusher can not achieve it is effectively broken,
And iron ore is be easy to cause to be adhered on broken working face, cause crusher failure；And by using after swing crushing principle, no
Reduction ratio can only be effectively improved, but also can be avoided the adherency of material, so as to improve crusher service life and reduce failure
Rate.
