The specific embodiment
Describe below in conjunction with the structure and the course of work of accompanying drawing the utility model.
As depicted in figs. 1 and 2; The revolving ring type permanent magnetic separator; Comprise permanent magnetism change 1, sorting groove 2, slag scraping mechanism 7, material inlet 5, mine tailing outlet 4 and wash tub pipe 6, permanent magnetism change 1 through retainer ring 9 parallel being set in side by side on the power transmission shaft 11, and is supported outstanding being loaded in the sorting groove 2 by power transmission shaft 11 with a determining deviation; Power transmission shaft 11 links to each other with motor 13 through shaft coupling 12; Power transmission shaft 11, bearing block 10 are fixed on the frame 3, and slag scraping mechanism 7 and wash tub pipe 6 are installed between the adjacent permanent magnetism change 1, and material inlet 5 places permanent magnetism change 1 middle and upper part; The mine tailing outlet places sorting groove 2 bottoms.Permanent magnetism change 1 is hexagon.Have liquid level visual windows 8 at the two ends of frame 3.Material inlet 5 places permanent magnetism change 3/1sts four eminences.
Like Fig. 3 and shown in Figure 4, permanent magnetism change 1 is made up of ring skeleton 14, permanent magnet 15 and annular cover plate 16, and annular cover plate 16 is connected with ring skeleton 14, and permanent magnet 15 is arranged in the space that ring skeleton 14 and annular cover plate 16 constituted.Between the adjacent permanent magnetism change 1 on the corresponding working face permanent magnet 15 press S-N utmost point alignment; Permanent magnet 15 on single permanent magnetism change 1 working face is by the S-N-S-N utmost point certain pitch arrangement of being separated by successively.
As shown in Figure 5, slag scraping mechanism 7 is made up of scum board 17 and collet 18, and scum board 17 cross sections become the U type, contact with permanent magnetism change 1 in the both sides of annular cover plate 16, and scum board 17 bottoms are fixed on the collet 18.
Like Fig. 6 and shown in Figure 7, material inlet 5 all is duck with mine tailing outlet 4.
The embodiment of the invention:
Selected mineral feed from material inlet with the ore pulp form, after ore pulp gets into the sorting groove, regulate the mineral pulp level in the sorting groove through the liquid level visual windows.Under the effect of magnetic field force, the magnetic thing is attracted to permanent magnetism change surface, when the permanent magnetism change goes to the slag scraping mechanism position, is scraped by slag scraping mechanism, and wash tub pipe is strengthened slag dumping; Namagnetic substance is along with ore pulp flows out from the mine tailing outlet.
The utility model is described to be the change of hexagon permanent magnetism, can effectively enlarge the working area of permanent magnetism change, and can not occur owing to causing runner to stop up after the saturated absorption magnetic of the extension permanent magnet thing of permanent magnetism change.After ore pulp got into runner, the extension permanent magnet of permanent magnetism change only can be adsorbed on the magnetisable material in the magnetic field force sphere of action because magnetic field force operating distance is limited; Be increased to 3/4ths eminences of permanent magnetism change when material inlet; The magnetisable material that is not adsorbed is past dirty naturally along runner; Because runner is shape wide outside and narrow inside,, just adsorbed by the permanent magnetism change when magnetisable material flow to magnetic force absorption place that can provide for permanent magnetism change correspondence permanent magnet naturally down.
The described slag scraping mechanism of the utility model can efficiently scrape the magnetisable material of permanent magnetism change surface adsorption.When the revolving ring type permanent magnetic separator was worked, magnetic-particle can be adsorbed in permanent magnetism change surface, because the slag-scraper Elastic Contact on permanent magnetism change surface, just can scrape the magnetisable material of permanent magnetism change surface adsorption.Scum board on the slag scraping mechanism is that elastomeric material is processed, and can effectively avoid slag scraping mechanism to contact with permanent magnetism change card rigidity and change brings to permanent magnetism damage; Because collet is to be processed by non-magnetic stainless steel, what can guarantee slag-scraper scrapes slag intensity and hardness.
The described permanent magnet arrangement of the utility model, the strict S-N utmost point alignment of pressing of the work magnetic system on the corresponding working face of adjacent permanent magnetism change.Under the identical condition of background magnetic field, the flux loss amount is lacked than open magnetic circuit in the closo magnetic circuit, and under the prerequisite that does not change magnetic field gradient, it is big that the magnetic field intensity of action space and magnetic field force are wanted.According to this principle; Through such layout, between the corresponding working face of adjacent two disks, form half-open road magnetic circuit, reduce flux loss; At the magnetic energy that does not improve magnetic material with do not change under the condition of magnetic field gradient, improve the magnetic field intensity and the magnetic field force of action space; Work magnetic system on the single permanent magnetism change working face is strict to be staggeredly arranged by the S-N-S-N utmost point successively mutually across a certain distance.Around main field, add auxiliary field in the opposite direction, not only can not weaken the magnetic field intensity of main field, can strengthen the magnetic field intensity of main field on the contrary.According to this principle; Around a pair of S-N pole field, add the N-S pole field; Can strengthen the S-N pole field; At the magnetic energy that does not improve magnetic material with do not change under the condition of magnetic field gradient, improve the magnetic field intensity of action space, and work magnetic system certain pitch arrangement of being separated by can effectively be avoided magnetic screening effect.
The utility model is described to be duck feed port and mine tailing outlet, can guarantee evenly to give ore deposit and even ore removal.
