Description
Technical field
The utility model relates to a kind of permanent magnetic wet type drum magnetic separator, especially relate to permanent magnetic wet type drum magnetic separator with pulsating field, be applicable to efficiently separating of strongly magnetic mineral and non magnetic ore, in order to improve concentrate grade or to obtain qualified concentrate containing in advance, can be widely used in industries such as metallurgy, mine.
Background technology
The Wet-type permanent magnet drum type magnetic separator is the effectively equipment that sorts the ferromagnetism iron mineral, and the unit type of being used widely at present is the CT type, and it is multiple diameter series such as 600, 750, 900, 1050, 1200mm that main specifications has barrel diameter.This model magnetic separator generally adopts Sr-ferrite magnetic material as magnetic source, also has the composite magnetic system even the full Rare-Earth Magnetic that adopt strontium ferrite to combine with rare-earth magnet to be.But because the magnetic field intensity of existing Wet-type permanent magnet drum type magnetic separator is higher, number of magnetic poles is few, ore pulp sorting liquid level is low, and handled strongly magnetic mineral easily produces reasons such as magnetic coagulation, therefore the sorting selectivity of common magnetic separator is not high, separating effect is relatively poor, and during as picking equipment, its amplitude that improves concentrate grade is limited.
Personnel are known in the present technique field, and strongly magnetic mineral such as magnetic iron ore can stay remanent magnetism after leaving magnetic field.Therefore can produce magnetic coagulation between the magnetic-particle, the poly-group of strong magnetic also can take place because of being subjected to the external magnetic field effect between the magnetic mineral in common drum magnetic separator in the process of minute magnetite.Be mingled with because of mechanical entrainment and magnetic in the poly-group of these magnetic, and wrapped up certain monomer gangue and lean intergrowth, thereby influenced the raising of concentrate grade, this also is the main cause that existing cartridge type low-intensity (magnetic) separator is difficult to increase substantially concentrate grade.
In order to improve the precision that sorts of magnetic plant, domestic relevant magnetic plant manufacturer has successively adopted multiple corrective measure, as adopting electromagnetism alternating magnetic field mode, reduce the magnetic field intensity of permanent magnetism equipment, adopt magnetic reconnection to close sorting, or the like, but more or less all exist such or such shortcoming.As the magnetic separation post of nearest invention and application, adopt electromagnetism alternating magnetic field mode exactly, promptly magnetic field cuts in and out, and with the poly-group of loose magnetic, throwing removes mechanical entrainment and magnetic is mingled with, and has certain effect for improving concentrate grade.But also exist shortcomings such as water consumption is big, device height is big, disposal ability is little.
Summary of the invention
The purpose of this utility model is exactly the problems referred to above that exist at prior art, and provide a kind of efficiency of separation height, disposal ability big, can increase substantially concentrate grade, and permanent magnetism pulsating field wet type drum magnetic separator simple in structure, easy and simple to handle, low cost of manufacture.
For achieving the above object, the utility model permanent magnetism pulsating field wet type drum magnetic separator by the following technical solutions:
The utility model permanent magnetism pulsating field wet type drum magnetic separator contains organic frame, give the ore deposit case, the sorting cell body, permanent magnetism cylindrical shell and transmission device thereof, magnetic system and adjusting device thereof, the permanent magnetism cylindrical shell places the sorting cell body, magnetic system is built in the bottom of permanent magnetism cylindrical shell, on the sorting cell body, be respectively equipped with the concentrate outlet, tailing outlet port, be characterized in: outer surface or inner surface at the permanent magnetism cylindrical shell along the circumferential direction are provided with the high magnetic conductive metal material of long strip type every a determining deviation, described magnetic is that the big cornerite magnetic of being made up of 6-9 magnetic pole is that its magnetic is that cornerite is in 120-160 degree scope.
Bottom, selected district at described sorting cell body has additional concentrate washings device, and water (flow) direction that this device sprayed and permanent magnetism cylindrical shell are perpendicular.
Above-mentioned high magnetic conductive metal material along the circumference of permanent magnetism cylindrical shell be evenly be arranged as suitable; Described sorting cell body is deep slot type half an adverse current type structure, and its liquid level is with to scan district's magnetic pole strength height corresponding, the structural shape of multipole to adapt to, big cornerite magnetic system; The feed hole area deflection of described sorting cell body is scanned the district, thereby has strengthened the selected effect of purpose mineral, helps improving concentrate grade.
Compare with existing common drum magnetic separator, the utility model has the following advantages after adopting technique scheme:
(1) magnetic is that cornerite is big, number of magnetic poles is many, sort belt length, and the magnetic field depth of interaction is big, has increased the magnetic rolling effect of the strongly magnetic mineral that is adsorbed on drum surface, removes the chance that is mingled with gangue thereby increased to throw, and helps improving the concentrate grade of magnetic iron ore.
(2) owing to be provided with high magnetic conductive metal material at drum surface, so cylindrical shell can form pulsating field at drum surface when rotating continuously, cuts in and out.This pulsating field can improve the sorting selectivity of this equipment greatly.
(3) disposed shallow/deep groove type half adverse current sorting cell body, it is higher that mine tailing is discharged the weir, and liquid level is higher in the groove, can give full play to the effect that sorts of the multipole magnetic of big cornerite system.
(4) in the bottom, selected district of sorting cell body, be provided with concentrate washings device, these flushing current dispel and cleaning function the poly-group of magnetic, can discharge the monomer gangue and the lean intergrowth that are mixed in the poly-group of magnetic, thereby reach the purpose that improves concentrate grade.
(5) feed hole area of sorting cell body deflection is scanned the district, thereby has strengthened the selected effect of purpose mineral, helps improving concentrate grade.
