The utility model content
In order to overcome the deficiency of existing magnetic separator faults frequent, technical problem to be solved in the utility model is to provide the lower magnetic separator of a kind of fault rate.
The technical scheme that its technical problem that solves the utility model adopts is: magnetic separator, comprise the disk that is connected with main shaft, back purge system and helical axis output materials device, horizontal plane arranges the water spray slag flushing device at place, disk center, and its water flow jet direction is pointed to the card of the nearly helical axis output of disk materials device one side.
Described back purge system is positioned at below the horizontal plane of disk center line place, and the center line of back purge system and plane, disk center line place and place, disk center horizontal plane have the angle of 18 °～20 °.
Described main shaft adopts axial thrust bearing near the bearing of motor one end.
The dissection type packing seal is adopted in the sealing of described main shaft.
The rubber skeleton sealing is adopted in the rotating shaft of described helical axis output materials device.

The discharging opening configuration gravity chute conveying device of described helical axis output materials device, for example, 45 ° of gravity chute conveying devices.
The beneficial effects of the utility model are: more be adapted to the magnetic separation operating mode of Rare Earth Mine, and fault rate is significantly reduced, the direct motion that is conducive to produce and reduce the equipment use cost.
Description of drawings
Fig. 1 is the structural representation of existing magnetic separator.
Fig. 2 is the structural representation of the utility model magnetic separator.
Be labeled as 1-motor, 2-shaft coupling in figure, 3-main shaft, 4-disk, the 5-slag flushing device of spraying water, the packing seal of 6-dissection type, 7-axial thrust bearing, 8-back purge system, 9-helical axis output materials device, 10-axial thrust bearing, the sealing of 11-rubber skeleton, the 12-motor, 13-shaft coupling, 14-gear pair, 15-gravity chute conveying device, 16-plane slag device, 17-suspension helical conveying device.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated.
As shown in Figure 1, existing magnetic separator comprises the disk 4 that is connected with main shaft 3, plane slag device 16, back purge system 8 and helical axis output materials device 9, the discharging opening configuration suspension helical conveying device 17 of helical axis output materials device 9.
As shown in Figure 1 and Figure 2, magnetic separator of the present utility model is compared with existing magnetic separator, at first be that plane slag device no longer is installed, change by the water spray slag flushing device 5 in disk 4 central horizontal face settings and will be adsorbed under slag on disk 4 rinses, its water flow jet direction is pointed to the card of the nearly helical axis output of disk 4 materials device 9 one sides, and the slag that rinses is sent via helical axis output materials device 9.Compare with the existing mode that scrapes with plane slag device, the mode of water spray flushing cinder can be according to the size adjustment water spray pressure of disk to the slag absorption affinity, generally adopt the water pressure about 0.3MPa～0.4MPa to get final product for Rare Earth Mine, damage to disk 4 cards is little, even if main shaft exists axial float slightly also not affect slagging-off efficient, alleviated canonical loading, the failure rate is low that water spray slag flushing device 5 is own, thereby improved the reliability of magnetic separator, reduced equipment failure rate.
As shown in Figure 2, compare with existing magnetic separator, the utility model has been adjusted the relative position of back purge system 8 with disk 4, described back purge system 8 is placed in below the horizontal plane of disk center line place, it is compared with prior art the setting height(from bottom) that has reduced back purge system 8, make it be in the orientation of following 18 °～20 ° of disk center line place horizontal plane, so that flushing water effectively dilutes removing to mud, impurity, thereby improved flush efficiency, alleviate unit load, also significantly improved original magnetic separator blockage.
As shown in Figure 2, described main shaft 3 adopts axial thrust bearing 7 near the bearing of motor 1 one ends, can effectively bear axial force, alleviates the load of unit and cycloidal planetary gear speed reducer, also the corresponding service efficiency that improves unit.
As shown in Figure 2, dissection type packing seal 6 is adopted in the sealing of described main shaft 3, and soft packing is loaded on the disk axle journal and replaces original-pack magnetic seal, can effectively control the excessive of iron oxide and water, because airtight and watertight padding is soft, has reduced the wearing and tearing of main shaft 3 axle journals.
As shown in Figure 2, rubber skeleton sealing 11 is adopted in the rotating shaft of described helical axis output materials device 9, reduce the wearing and tearing of its axle journal, and sealing effectiveness is more good.
As shown in Figure 2, the rotating shaft of described helical axis output materials device 9 is adopted axial thrust bearing 10 near the bearing of motor one end, can effectively bear axial force, reduces the fault rate of helical axis output materials device 9.
As shown in Figure 2; the discharging opening of described helical axis output materials device 9 disposes gravity chute conveying device 15; gravity chute conveying device 15 costs are low, easy care, failure rate is low; the equipment fault of effectively having avoided originally the frequent breakage due to suspension helical conveying device 17 to cause is shut down; according to the magnetic separation operating mode of Rare Earth Mine, 45 ° of gravity chute conveying devices of recommendations for selection.
Compare with existing magnetic separator, magnetic separator of the present utility model more is adapted to the magnetic separation operating mode of Rare Earth Mine, and fault rate is significantly reduced, the stable smooth operation that is conducive to produce and reduce the equipment use cost.
