Description
Technical field
The utility model belongs to magnetic plant, particularly a kind of magnetizing mediums that is used for high-gradient magnetic separation apparatus.
Background technology
The proposition of high-gradient magnetic separation theory gives magnetic concentration circle with qualitative leap, and the mineral species that allows to magnetic separation increases, and the granularity upper and lower limit broadens.The continuous high gradient magnetic separator that successively occurs in the occasion of handling low content magnetic thing and fine fraction magnetic thing has the strong magnetic high gradient magnetic separator of the flat ring type of electromagnetism, permanent magnetism and electromagnetism vertical ring high-gradient magnetic separator etc.These equipment be widely used in the weak magnetic fine particle embedding cloth of sorting ore, contain the recycling of golden mine tailing, from ore in sand form, reclaim goethite stone and rutile, the sorting industrial mineral, as kaolin, fluorite, apatite, from fine coal, separate in the industrial production such as wastewater treatment in pyrite and ash content, steel plant and power plant.
Be applied to the magnetizing mediums of high gradient magnetic separator at present, basic structure mainly contains several forms such as spherical magnetizing mediums, clavate magnetizing mediums, tooth plate shape magnetizing mediums and filament magnetizing mediums.Above-mentioned magnetizing mediums influences the further raising of high gradient magnetic separator separation performance to some extent owing to be subjected to the restriction of structure.For example spherical magnetizing mediums is difficult for stopping up, but does not produce higher magnetic field intensity; Tooth plate shape and filament magnetizing mediums can produce higher magnetic field intensity, but work the time is stopped up easily.And the clavate magnetizing mediums is smooth cylindrical magnetic dielectric rod, though when work is difficult for stopping up, can not produce higher magnetic field gradient simultaneously.
The utility model content
The utility model is at the existence of the problems referred to above, provides a kind of difficult obstruction, magnetic field gradient bigger, can reduce tailings grade when guaranteeing concentrate grade, improves the magnetizing mediums of the high-gradient magnetic separation apparatus of the rate of recovery.
Goal of the invention of the present utility model is achieved through the following technical solutions.
A kind of magnetizing mediums that is used for high-gradient magnetic separation apparatus comprises some steel plates that are installed in the upright wheel of sorting, and this steel plate inboard and the outside are shaggy tooth, for double wedge double wedge are arranged between steel plate and the steel plate.Described shaggy tooth can be in circle-arc tooth, involute teeth, ellipse tooth, hyperbola tooth, parabola tooth or the cycloid tooth a kind of.Described shaggy tooth is the parabola tooth.The space width of described parabola profile of tooth magnetizing mediums is 8-20mm, and tooth angle is 100-150 °.The space width of described parabola profile of tooth magnetizing mediums is 12mm, and tooth angle is 127 °.
Distance between described steel plate and the steel plate is 1-5mm.Distance between steel plate and the steel plate is 2mm.
The utlity model has following advantage:, be difficult for stopping up the workflow smoothness 1, because ore pulp is big by the space.2, the magnetic induction intensity that forms between crown and tooth paddy is very high.3, make simply, with low cost.
Description of drawings
Fig. 1 is the utility model magnetizing medium structure schematic diagram;
Fig. 2 is the utility model magnetizing mediums action principle schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1 and Figure 2, for the ease of the passing through, discharge and clean of ore particle, the mounting means of magnetic conduction pointed tooth steel plate magnetizing mediums is that crown is installed crown.The structural parameters of multilayer magnetic conduction pointed tooth steel plate magnetizing mediums mainly comprise distance between tooth angle, space width and the steel plate of the tooth utmost point.When drawing distance L between tooth angle a=127 °, space width S=12mm and the steel plate=2mm by test, it is best that the magnetic induction intensity of tooth interpolar and magnetic field gradient reach.
Add magnetizing mediums of the present utility model in closed magnetic is after, magnetic induction intensity obviously increases 4～6 times, and it is that the uniform magnetic field that produces has become non-uniform magnetic-field that magnetizing mediums of the present utility model makes closed magnetic, has improved magnetic induction intensity and magnetic field gradient.When not adding magnetizing mediums of the present utility model, divide the magnetic field intensity in constituency smaller, and change of magnetic field strength is smaller, magnetic field is more even.
The magnetic induction intensity that can draw the crown place by the magnetic field intensity of measuring the utility model magnetizing mediums mesostyle and corresponding teeth paddy place is very high, and tooth paddy zone is opposite, magnetic induction intensity is very low, and this is because induced field is in the same sex, tooth paddy place because distance is near, induced field is cancelled out each other obviously, cause induced field to be characterized by low-intensity magnetic field, and at the crown place, because distance is distant, the effect of cancelling out each other is not obvious, and induced field is characterized by high-intensity magnetic field.Therefore the magnetic ore particle mainly is adsorbed on the crown zone in magnetic separator.Along with the increase of the degree of depth, the variation of the magnetic field intensity of crown and tooth paddy is all smaller.Explanation is more even along the vertical magnetic field of pointed tooth steel plate, but the variation of the magnetic field intensity from crown to tooth paddy is bigger, and magnetic field gradient is bigger.
Workflow of the present utility model is as follows:
Selected mineral enter high gradient magnetic separator with the ore pulp form, after ore pulp enters sorting chamber, under the effect of magnetic field intensity and magnetic field gradient, the magnetic thing is in magnetizing mediums of the present utility model surface absorption, the no field region that turns to along with the upright wheel of sorting, owing to be not subjected to the effect of magnetic force, under the acting in conjunction of the impulsive force of the flushing water of self gravitation and wash tub pipe, discharge by the concentrate bucket, non-magnetic material because of the effect that is not subjected to magnetic force along with the motion of current is finally discharged from the mine tailing passage.
The utility model drives ore pulp in conjunction with pulsing mechanism and produces pulsation, can make the mine particle group maintenance loose condition (of surface) branch constituency in, makes that the magnetic ore particle is easier is caught by magnetizing mediums, makes non magnetic ore particle pass magnetizing mediums of the present utility model as early as possible and enters into mine tailing.Thereby reach rinsing and be adsorbed on the lip-deep magnetisable material of the utility model magnetizing mediums, the purpose of sloughing the namagnetic substance that is mingled with.
