Description
Technical field
The invention belongs to field of mechanical technique, particularly relate to a kind of separation ring of high gradient magnetic separator of ore separators.
Background technology
The proposition of high-gradient magnetic separation theory gives magnetic separation circle with qualitative leap, and the mineral species that allows to magnetic separation increases, and the granularity upper and lower limit broadens.
Early stage high gradient magnetic separator is periodic, also claims magnetic filter, and this kind equipment is used widely in handling the occasion that magnetic material content is extremely low and granularity is very thin.
The continuous high gradient magnetic separator of Chu Xianing has the strong magnetic high gradient magnetic separator of the flat ring type of electromagnetism, permanent magnetism and electromagnetism double-vertical ring high-gradient magnetic separator immediately.The electromagnetism horizontal disk high gradient magnetic separator is owing to give the ore deposit identical with the rinse water direction, so cause machinery to stop up easily, the permanent magnet vertical ring high gradient magnetic separator is owing to the as easy as rolling off a log formation strongly magnetic mineral at the feed port place, the particularly accumulation of iron filings and magnetic takes place stop up, the magnetic separation of electromagnetism vertical ring high-gradient is owing to give the ore deposit opposite with the flow direction of concentrate flushing water in media stack, so being not easy to take place machinery stops up, again owing to be electromagnetism, so when exciting curent does not exist, strongly magnetic mineral and iron filings are easy to come off at the feed port place, and magnetic is stopped up and can not taken place.
For being mingled with of nonmagnetics in the product that deperms, vibration and pulsating high gradient magnetic separator have appearred, as Chinese patent 86106144.6 disclosed a kind of pulsating high gradient magnetic separators, it can make the richness that is recovered material long-pending than improving, simultaneously because the panting action of water has reduced mechanical obstruction.But the core work principle of this kind equipment is that to be based upon the pulsation direction of ore pulp or water consistent with magnetic line of force direction, when the pulsation direction of ore pulp or water is consistent with magnetic line of force direction.The particle swarm that is adsorbed on the dielectric surface only exists along a side of magnetic line of force direction unanimity, at this moment, move back and forth the positive pressure of the fluid force that produces or draw particle swarm by ore pulp, because there is the existence of medium particle swarm front or back, the cushioning effect of its internal liquid, the fluid force that makes is retarded, is unfavorable for the evacuation of particle swarm, and the more weak intergrowth of the nonmagnetics that is mingled with in the particle swarm and magnetic can not be cleaned out effectively.Therefore, separating effect is also more limited, can not take into account concentration ratio and metal recovery rate, output concentrate and tailings, concentrate grade and metal recovery rate can only be protected one, if two all will be protected and will increase by one section operation again, increase investment and operating cost, namely when obtaining high-grade concentrate, metal loss is bigger in the mine tailing; Otherwise when tailings grade is effectively controlled, the difficult quality guarantee of concentrate.Outside it, the medium of this magnetic separator is arranged as intersection, so medium stops up easily, often is difficult to cleaning in case take place to stop up.
Chinese patent 02134298.9 discloses a kind of double-frequency pulse and double-vertical ring high-gradient magnetic separator, comprise separation ring, magnetic system, be characterized in the magnetic system of horizontal magnetic force line that can be in the sorting space and ore pulp is produced with the perpendicular reciprocating motion of the magnetic line of force below separation ring, being provided with the combination of adopting different reciprocal impact ore deposits to flow the double-frequency pulse device of frequency energy output mine tailing and chats by two groups.This patent is owing to adopt sorting space and unique double-frequency pulse device by left and right magnetic pole and the rotating disk outer rim magnetic conduction part horizontal magnetic force line that forms to combine, the fluid dynamic that can produce according to the ore pulp pulse section different in magnetic separator sorting space with the magnetic force that magnetic field produces be to the difference of the different mineral grain group active force of magnetic, especially when magnetic line of force direction be level and and the ore pulp vibration-direction of pulse generation when perpendicular.The particle swarm that is adsorbed on the dielectric surface only exists along a side of magnetic line of force direction unanimity, at this moment, it is tangent that the fluid force direction that move back and forth to be produced by ore pulp and dielectric surface particle swarm are assembled a side, ore pulp just passes particle swarm inside, it is sheared and cleans, the nonmagnetics and the more weak intergrowth particle of magnetic that are mixed in the particle swarm are cleaned out, thereby increase substantially separating effect.The medium of this magnetic separator is arranged as matrix, so the difficult obstruction of medium, also is easy to cleaning in case take place to stop up.But the sorting space of this magnetic separator is big inadequately, mainly is the restriction that is subjected to the thickness of field pole distance and medium.Because the too big sorting space background of pole span field intensity will reduce, the number of ampere turns that perhaps can increase coil solves, but this need increase power consumption greatly, and the thickness that increases medium can make concentrate unload the ore deposit and become difficult.The medium of more volume not quite just can't be loaded in the sorting space, and this just influences the treating capacity of equipment, and particularly when equipment need maximize, the contradiction of the thickness of medium and the increase of volume and clogging seemed more outstanding.
Summary of the invention
The objective of the invention is at above-mentioned existing problems and deficiency, a kind of reliable in structure is provided, can improves the treating capacity of magnetic separator greatly, particularly can adapts to the separation ring of high gradient magnetic separator of the magnetic plant of maximization.
Technical scheme of the present invention is achieved in that
The separation ring of high gradient magnetic separator of the present invention is characterized in comprising ring body on the rotating disk that is installed on magnetic separator and that can rotate synchronously with rotating disk and is installed at least two layers of this ring body periphery being used for the arc grooves, cartridge of ccontaining and mounting medium box, being installed on unloading the ore deposit device, being installed on connecing the ore deposit device, being installed on the ore feeder of ring body of week in each arc groove respectively of each arc groove periphery respectively.
Wherein, above-mentioned cartridge is to be welded according to certain rules by the magnetic stainless steel rod, and is provided with dividing plate between the two adjacent cartridges.
Above-mentioned ring body is connected to form by heavy wall ring and thin-walled ring, and heavy wall ring and thin-walled ring are installed on the rotating disk by bearing holder (housing, cover) respectively.
The present invention is owing to adopt the structure that at least two layers cartridge is arranged at the ring body device, thereby the thickness of the cartridge of each layer can be reduced greatly, because the cartridge number of plies has increased, make in the separation ring more jumbo medium can be installed, guaranteeing that it has on the basis of enough magnetic field intensities, effectively increase the sorting space, thereby improve the treating capacity of magnetic separator greatly, particularly when magnetic separator equipment need maximize, this separation ring structure can guarantee effectively that more it can install more medium easily and reliably, fully guarantee its separating effect, and simple and reliable for structure, cost is low, the efficient height.
