Description of drawings
Fig. 1 is the structural representation of the magnetic separation retracting device of the trickle iron ore material of the utility model ferromagnetism.
Among the figure: 1-right baffle-plate, 2-charging aperture, the reciprocating type scraper plate of 3-, the right baffle plate of 4-, 5-guide plate or oscillatory type screen cloth, the outlet of 6-gangue, 7-midseam or the outlet of intergrowth ore deposit, the outlet of 8-concentrate, 9-sorting magnetic field, 10-charging baffle plate.
The specific embodiment
In conjunction with accompanying drawing the utility model is done further explanation:
As shown in Figure 1, the magnetic separation retracting device of the trickle iron ore material of present embodiment ferromagnetism is provided with charging aperture 2 above sorting magnetic field 9, and the below in said sorting magnetic field 9 is provided with discharging opening.The left side in said sorting magnetic field 9 is provided with right baffle-plate 1, and the right side in said sorting magnetic field is provided with right baffle plate 4; Magnetic directions in the said sorting magnetic field 9 be from right baffle-plate 1 to right baffle plate 4, be parallel to ground and perpendicular to the plate face of right baffle-plate and right baffle plate; Said charging aperture 2 closes on right baffle-plate 1 and is provided with.Said discharging opening comprises gangue outlet 6, midseam or the outlet 7 of intergrowth ore deposit and the concentrate outlet 8 that is arranged in order from left to right.Said charging aperture 2 places are provided with guide plate or oscillatory type screen cloth, are provided with charging baffle plate 10 at guide plate or oscillatory type screen cloth away from a side of right baffle-plate 1.Be provided with reciprocating type scraper plate 3 in the said sorting magnetic field 9, reciprocating type scraper plate 3 closes on right baffle plate 4 and is provided with, and the working position of said reciprocating type scraper plate 3 contacts with the plate face of right baffle plate 4.The magnitude of field intensity in said sorting magnetic field 9 is more than the 4000G.The plate face that said magnet baffle plate contacts with the working position of said reciprocating type scraper plate 3 is the smooth plate face.
The trickle iron ore material of ferromagnetism evenly gets in the sorting magnetic field 9 from the guide plate or the oscillatory type screen cloth 5 of charging aperture 2; The trickle iron ore material of ferromagnetism receives the effect of magnetic force, gravity and air drag in sorting magnetic field 9; Wherein: gangue receives the effect of gravity and air drag; Its horizontal displacement is minimum, separates from the gangue outlet 6 in left side; Concentrate receives the effect of gravity, air drag and magnetic force; Suffered magnetic force direction from said right baffle-plate 1 to said right baffle plate 4; Because suffered magnetic force is greater than the suffered magnetic force of midseam or intergrowth ore deposit, thereby horizontal displacement is maximum, separate from the concentrate outlet 8 on right side; Midseam or intergrowth ore deposit receive the effect of gravity, air drag and magnetic force, because the suffered magnetic force of midseam or intergrowth ore deposit is little than the suffered magnetic force of concentrate, thereby its horizontal displacement is separated from midseam or intergrowth ore deposit outlet 7 between gangue and concentrate.Reciprocating type scraper plate 3 can come out attached to the concentrate on the plate face of said right baffle plate 4 scrapes horizontal displacement greatly from said concentrate outlet 8.
