A crevice oblique magnetic group is also provided between the adjacent magnetic poles. The permanent magnet drum type medium intensity magnetic separator of the utility model has the advantages of having a reasonable magnetic system structure, a reasonable distribution of magnetic lines and a highly separation magnetic field intensity which can be used for separating iron minerals with pseudomorph and half pseudomorph, purifying nonmetallic minerals with removing of iron and reconcentrating of tailings in magnetic separation plants.
Description
The utility model relates to a kind of permanent magnetism midfield high intensity magnetic separation equipment, especially by the permanent magnetism midfield intensity magnetic separator that comprises that magnetic system, cylindrical shell, cell body, frame, transmission device etc. are formed, can be widely used in separating of medium magnetic mineral and non magnetic ore, to sorting illusion, half illusion mineral, and nonmetallic ore deironing purification such as quartz sand, feldspar powder etc. is particularly suitable, also is effective equipment that magneticore-dressing plant's mine tailing resource reclaims again.
Sixties end, development along with ferrite permanent-magnet materials, China's strongly magnetic mineral sorts the permanent magnetismization that has progressively realized magnetic plant, the seventies, succeeding in developing of permanent-magnet drum type magnetic separators such as φ 600, φ 750, φ 1050 series, in black, nonferrous mine and coal system extensive use, bring into play significant role aborning rapidly, improved the sorting index in ore dressing plant greatly.Along with the continuous exploitation in mine, iron ore dilution phenomenon is on the rise, and raw ore iron grade and magnetic rate are more and more lower, and still using the lower full ferrite magnetic of field intensity is magnetic separator, just is difficult to obtain good separating effect.Since the nineties, along with the development of rare earth permanent-magnetic material, the magnetic of permanent-magnet drum type magnetic separator system has been to develop into full Rare-Earth Magnetic to be structures such as the compound magnetic of rare earth and ferrite system by original single full ferrite magnetic.It is drum magnetic separator that " the Chinese preparation equipment application manual " that China Machine Press publishes in April, 1994 (middle volume) P138 page or leaf has been introduced the compound magnetic of a kind of rare earth, the magnetic of this magnetic separator system is that the rare earth material (neodymium iron boron) by a small amount of high magnetic characteristics becomes with ferrite magnetic patch complex group, the Rare-Earth Magnetic material is used for strengthening mine tailing and scans the district, the average magnetic induction intensity of tube table reaches 200mT, and mine tailing is scanned stiffened region can reach 280mT.Owing to adopted the compound magnetic of rare earth system, improved the tube surface electric field intensity, enlarged the range of application of this machine, improved the concentrate rate of recovery.But still can not satisfy the recovery of medium magnetic mineral such as illusion, half martite thing, when purifying especially for the nonmetallic mineral deironing, using existing ferrite magnetic system or the compound magnetic of ferrite rare earth is magnetic separator, be difficult to and the medium magnetic mineral of the overwhelming majority can be sorted out, product does not reach requirement, if the back operation has intensity magnetic separator, can pose a big pressure to intensity magnetic separator, very easily result in blockage, influence ordinary production.
The purpose of this utility model is exactly at the deficiencies in the prior art, and a kind of magnetic architecture is reasonable, the magnetic line of force distributes rationally, sorting magnetic field intensity height and provide, field intensity drum magnetic separator in the permanent magnetism applied widely.
For achieving the above object, one of scheme that the field intensity drum magnetic separator adopts in the utility model permanent magnetism is: it comprises magnetic system, cylindrical shell, cell body, frame, transmission device etc., magnetic is sector structure, hang on the power transmission shaft in the cylindrical shell, be characterized in: magnetic system is to be combined by the compound magnetic group of ferrite magnetic group, Rare-Earth Magnetic group, ferrite and rare earth, ferrite magnetic group, Rare-Earth Magnetic group, ferrite and the compound magnetic group of rare earth respectively with cell body to mining area, branch constituency and to unload the mining area corresponding.
For further improving tube surface induction intensity, the oblique magnetic magnetic of crack group is set also between the adjacent pole of magnetic group.
For achieving the above object, the field intensity drum magnetic separator also can adopt another technical scheme in the utility model permanent magnetism: it also comprises magnetic system, cylindrical shell, cell body, frame, transmission device etc., magnetic is sector structure, hang on the power transmission shaft in the cylindrical shell, be characterized in: the magnetic group that described magnetic is is full Rare-Earth Magnetic group, sets up magnetic group arrangement for adjusting height under the magnetic group at two ends.
For further improving tube surface induction intensity,, the oblique magnetic group of crack is set also at the adjacent pole crevice place of magnetic group.
The utility model has the following advantages after adopting technique scheme:
(1) the magnetic group of branch constituency correspondence is full Rare-Earth Magnetic group, branch constituency tube surface electric field intensity is improved greatly, the branch constituency tube surface electric field intensity of scheme one, two can help reclaiming the deironing purification of illusion, half illusion iron mineral and nonmetallic mineral respectively up to 350mT～500mT, 500mT～800mT.
(2) the field intensity height that give mining area, branchs constituency, unloads the mining area is different, along magnetic be surperficial circumferencial direction not only the pole orientation exchange change, and magnetic field intensity, the magnetic field degree of depth, magnetic field gradient also change, and is more suitable for the sorting to mineral, helps raising and sort precision.
(3) the oblique magnetic group of the crack of Zeng Jiaing makes tube surface electric field intensity integral body improve, and helps improving the rate of recovery of medium magnetic mineral, fine mineral.
(4) help simplifying sorting process.To the sorting process of former weak magnetic reinforcement magnetic, the one midfield high intensity magnetic separation that can utilize fully that has replaces the running cost of the expense of reducing investment outlay greatly and equipment.
For describing field intensity drum magnetic separator in the utility model permanent magnetism in detail,, it is described further below in conjunction with drawings and Examples:
Fig. 1 is a field intensity drum magnetic separator master TV structure schematic diagram in the utility model permanent magnetism.
Fig. 2 is the right TV structure schematic diagram of field intensity drum magnetic separator in the utility model permanent magnetism.
Magnetic when Fig. 3 adopts the compound magnetic group of permanent-magnet ferrite magnetic group, full Rare-Earth Magnetic group, permanent-magnet ferrite and rare earth for field intensity drum magnetic separator in the utility model permanent magnetism is side view.
