The magnetic-type gyratory crusher of the present invention utilizes magnetic force to make mantle move, improve the structure of traditional round conic crusher, to rely on the rotational motion mechanism that magnetic force rotates to replace taper gear pair and eccentric bushing pair, avoid the potential faults that the secondary sliding friction of the taper gear pair in high-speed motion, eccentric bushing brings, enable gyratory crusher to be rotated position and run safely and steadly.
Accompanying drawing explanation
Fig. 1 is the structural representation of the magnetic-type gyratory crusher of the present invention.
Detailed description of the invention
Technical scheme in the embodiment of the present invention will be carried out clear, complete description below.
Fig. 1 is the structural representation of the magnetic-type gyratory crusher of the present invention.As it is shown in figure 1, the magnetic-type gyratory crusher of the present invention includes mantle 1, supports axle 8 and mainframe 2；Support axle 8 is fitted vertically and is installed on mainframe 2, and the top supporting axle 8 is provided with spherical support watt；Mantle 1 includes the inner chamber of bottom opening, is fixedly installed the support portion of dome shape in the inner chamber of mantle 1, and mantle 1 is arranged in the spherical support watt supporting axle 8 top by described support portion.
Rotation (bias) motion of the magnetic-type gyratory crusher of the present invention is described below.
Fixedly mount permanent magnet 3 in the bottom of mantle 1, the magnetic pole of permanent magnet 3 inwall is contrary with the magnetic pole of outer wall.Being provided with at least three the first electric magnet 7 on mainframe 2, the first electric magnet 7 is circumferentially distributed around permanent magnet 3 outer wall, and a magnetic pole of the first electric magnet 7 is relative with permanent magnet 3 outer wall and contrary with the pole polarity of permanent magnet 3 outer wall.The number of the first electric magnet 7 is preferably 8 to 12.
For electrically connecting with the first electric magnet 7 for the power distribution equipment 5 of the first electric magnet 7 power supply.Power distribution equipment 5 makes the first electric magnet 7 obtain electric clockwise or counterclockwise successively.Successively obtain two electric the first electric magnet 7 and can be called previous first electric magnet and later the first electric magnet, it is possible to make later the first electric magnet obtain electric after previous first electric magnet dead electricity.Must electric can being controlled by the controller (such as single-chip microcomputer or programmable logic controller (PLC)) in power distribution equipment 5 with dead electricity of first electric magnet 7.
Supporting, axle 8 arranges at least three the second electric magnet 6 around cylinder, second electric magnet 6 and the first electric magnet 7 are correspondingly arranged, that is: in first electric magnet 7 being correspondingly arranged and second electric magnet 6, a magnetic pole of the second electric magnet 6 and a magnetic pole strength of the first electric magnet 7 are provided opposite to.Therefore, the number of the first electric magnet 7 is preferably identical with the number of the second electric magnet 6, and the number of the first electric magnet 7 is preferably also 8 to 12.One magnetic pole of the second electric magnet 6 and a magnetic pole of the first electric magnet 7 are relatively and opposite polarity.Power distribution equipment 5 can be electrically connected with the second electric magnet 6, and be that the second electric magnet 6 is powered.Power distribution equipment 5 can make the first electric magnet 7 and the second electric magnet 6 simultaneously electric, simultaneously dead electricity.
In order to prevent the second electric magnet 6 from colliding with permanent magnet 3, cause device damage, supporting, axle 8 is provided with rubber washer 4.
In use, power distribution equipment 5 is by making the energising set, power down sequence and conduction time the first electric magnet 7 and the second electric magnet 6 obtain electric and dead electricity.The first relative electric magnet 7 and the second electric magnet 6 form one group of electric magnet, and this group electric magnet can simultaneously electric, dead electricity, first electric magnet 7 attracts permanent magnet 3 when obtaining electric, and the second simultaneously relative with the first electric magnet 7 electric magnet 6 repels permanent magnet 3 when obtaining electric；Then the first current electric magnet 7 and the power-off simultaneously of the second electric magnet 6 are made, and connect next and organize the first electric magnet 7 and the second electric magnet 6, mantle 3 can move to obtaining the first electric electric magnet 7 direction, the first electric magnet 7 and the second electric magnet 6 is so made to obtain electric, dead electricity in order, so that mantle 1 is rotated (circle swing), it is achieved the crushing function of gyratory crusher.
Above-mentioned gyratory crusher also includes the rolled mortar wall coordinated with mantle 1, and described rolled mortar wall is fixedly mounted in adjusting sleeve, and described adjusting sleeve is combined with splicing sleeve by screw thread；Described splicing sleeve is placed on mainframe 2, and the contact surface contacted with mainframe 2 includes the conical surface.
In the process that above-mentioned gyratory crusher is rotated, the support portion of the dome shape of mantle 1 contacts with the spherical support watt supporting axle 8 top, decrease friction, when mantle 1 carries out high speed rotary motion, the support portion of the dome shape of mantle 1 does not even contact with the spherical support watt supporting axle 8 top.Set (burning set) phenomenon is ground therefore, it is possible to be prevented effectively from.
Obviously, described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of protection of the invention.
