Abstract
The utility model relates to a component of mineral processing equipment, in particular to a gradient toothed magnetic medium box for a high gradient magnetic separator. The gradient toothed magnetic medium box is provided with a front positioning plate and a back positioning plate; a plurality of medium bars are densely distributed between the two positioning plates; and in addition, at least one fixing lug is welded in a position(s) close to the upper part(s) of the outer wall surface(s) of one positioning plate or the front positioning plate and the back positioning plate. The gradient toothed magnetic medium box is characterized in that the medium bars adopt magnetic-conduction stainless steel rods, and the outer surfaces of the medium bars are toothed; and the density of the medium bars arranged on the positioning plate is increased in a gradient manner from down to up. The gradient toothed magnetic medium box solves the problems of the conventional magnetic medium box, including large reluctance, high energy consumption, mine unloading impediment and the like, and is mainly applied to the high gradient magnetic separator for metallurgy mineral processing equipment.
Description
Technical field
The utility model relates to the parts in preparation equipment, especially a kind of high gradient magnetic separator gradient sawtooth pattern cartridge.
Background technology
The separation ring of high gradient magnetic separator has 24～128 magnetic medium boxes to be evenly distributed on the surface of rotating cylinder according to the difference of swivel diameter, and the magnetic matrix of magnetic medium box commonly used has netted medium and pole medium.Netted medium is better to reclaiming trickle ore particle effect, but has " magnet short-cut path " phenomenon less use with holding susceptible to plugging problem between medium.
The disclosed a kind of high gradient magnetic separator of Chinese patent 200610132431.9 preparation method of pole magnetizing mediums, its magnetizing mediums is to be evenly arranged between two location-plates by interval 2～5mm by 1～2,000 dielectric rod, dielectric rod is generally made of Cr series magnetic stainless steel pole, diameter is 2～4mm, and length is between 50～150mm.Because having " magnet short-cut path " phenomenon and not susceptible to plugging advantage, the pole medium is not widely used.But the magnetic field gradient of this pole medium is not high, and the magnetic resistance in magnetic circuit is too large and energy consumption is high.
The disclosed a kind of equilateral rhombus medium of Chinese patent 201110306909.6, its magnetic field gradient increases than pole medium, also without " magnet short-cut path " phenomenon.But the more difficult processing and fabricating of this medium also is difficult for being assembled into cartridge.
Above two kinds of magnetic medium of high-gradient magnetic separator boxes, its magnetic field gradient is all not bery high, want to improve again the richness of recovered material long-pending than and metal recovery rate only have the increase exciting curent, the magnetic field force in increasing sorting space.Simultaneously the arrangement pitch due to every group of dielectric rod equates, stops up in order to reduce machinery, needs to strengthen discharging bath pressure and the water yield, or the wind-force that increases by cover Chinese patent 200610132432.3 disclosed a kind of high gradient magnetic separators unloads the ore deposit device.Cost of investment increases.
Summary of the invention
The purpose of this utility model will solve exactly that existing magnetic medium box magnetic resistance is large, energy consumption is high, unload the problems such as the ore deposit is not smooth, provides a kind of high gradient magnetic separator with gradient sawtooth pattern cartridge.
Concrete scheme of the present utility model is: improve for existing magnetic medium box, location-plate before and after it has, be densely covered with many dielectric rods between two location-plates, and at the outside wall surface top section of one or two location-plates in front and back at least one fixedly ear that has been welded, it is characterized in that: described dielectric rod is the magnetic stainless steel bar, and its outer surface is broached-tooth design; The arrange density of described dielectric rod on location-plate is to increase in gradient from bottom to top.
Dielectric rod described in the utility model is the magnetic stainless steel threaded screw rod, and its outer surface has the screw thread sawtooth.
The diameter of the bar of magnetic stainless steel described in the utility model is 2-4mm, and length is 50-150mm.
Location-plate described in the utility model is the thick non-magnetic corrosion resistant plate of 2-4mm.
Described in the utility model fixedly ear be that to adopt thickness be that the non-magnetic corrosion resistant plate of 4-6mm is made, have the installing hole of a Φ 10.5-19.5mm on it.
The utility model is owing to adopting sawtooth pattern magnetic stainless steel dielectric rod, its serrated slot had both increased the effective area of magnetic matrix, improved the long-pending ratio of the richness that is recovered material, and the curvature because of sawtooth point and groove is larger again, its magnetic field gradient is very high, and the effect of the weak magnetic mineral that recovery size is fine is fine; Be conducive to the absorption of weak magnetic mineral, improve metal recovery rate.Dielectric rod in the utility model density of arranging has adopted the graded design, very is conducive to unload the ore deposit.When cartridge forwarded the bottom to, large dielectric rod flow to cartridge to ore pulp from the interval, and the dielectric rod little from the interval flows out, and is conducive to the absorption of mineral.When cartridge forwarded the top to and unloads the ore deposit, little dielectric rod flow to cartridge to flushing water from the interval, and the dielectric rod that concentrate is large from the interval flows out, thereby is conducive to unload the ore deposit.
The utility model can improve recycle rate of magnet-selection machine, reduces energy consumption, conveniently unloads the ore deposit.
