Abstract
The utility model relates to a permanent-magnet multi-gradient field strength adjustable magnetic separator which can be widely used for the separation of magnetic ores and non non-magnetic ores in magnetic separation plants. The magnetic separator adopts a slotted hole form to fix a magnetic system on a lower shaft clamp, so that the distance between the magnetic system and a circular cylinder can be adjusted within the length of the slotted hole. The magnetic unit part of the magnetic system, from the scavenging area of the magnetic separator to the concentrating area, is designed into a step shape, and the heights of the magnetic units are reduced gradually. The utility model can adjust the field strength on the surface of the circular cylinder as required to improve the separating effect. In addition, the field strength of the scavenging area is relatively high and the field strength of the concentrating area is relatively low, which is beneficial to increasing the recovery rate of ore concentrate and the concentrate grade.
Description
The utility model belongs to a kind of permanent-magnet drum type magnetic separator, can be widely used in the sorting of magneticore-dressing plant's magnetic mineral and non magnetic ore, and is particularly suitable to Benefication of magnetite.
At present, magneticore-dressing plant is used to sort the preparation equipment of strongly magnetic mineral, mostly is permanent-magnet drum type magnetic separator, and such magnetic separator generally has easy to use, the advantage that disposal ability is big." magnetoelectricity ore dressing " (in January, the 1980 front page P52 of metallurgical industry publishing house page or leaf) introduced a kind of typical permanent-magnet drum type magnetic separator, and this magnetic separator mainly is made up of magnetic system, cylinder, under casing three parts, and magnetic system is fixed on the cylinder main shaft.The subject matter that this magnetic separator exists is that after the equipment moulding, the distance between magnetic system and the drum surface can not be adjusted, thereby the magnetic induction intensity of drum surface remains unchanged with regard to corresponding, when needs change product quality, when improving concentrate grade, this magnetic separator just can not meet the demands; In addition, the magnetic group height of several utmost points equates on the cross section of this magnetic separator magnetic system, and drum surface magnetic induction intensity along the circumferential direction evenly distributes, thereby identical to selected district magnetic induction intensity from scanning the district.But in ore dressing is produced, scanning the district in order to improve metal recovery rate, magnetic field intensity should be greatly; In order to improve concentrate grade, magnetic field intensity should be smaller in selected district.
The utility model purpose is exactly distance between the magnetic the adjusted system that proposes at the problems referred to above that existing permanent-magnet drum type magnetic separator exists and cylinder, from scanning the permanent magnetism polygradient magnetic separator that the district reduces by gradient to selected district field intensity, thereby improve the concentrate index.
For achieving the above object.The upper limb that axle clamp down of the present utility model or magnetic are has some slotted holes, will descend axle clamp and magnetic system to fix in the slotted hole position with bolt, thereby the distance between realization magnetic system and the cylinder is regulated the size of change drum surface magnetic induction intensity in the slotted hole length range; From magnetic separator scan district to the magnetic in selected district be the magnetic group partly for stepped ramp type design, magnetic group height reduces gradually, cylinder outer surface magnetic induction intensity distinguishes extremely from scanning that selected district reduces by gradient.
The many gradients of the utility model permanent magnetism are adjustable field intensity magnetic separator, comprise cylinder, magnetic system, under casing, axle clamp etc., it is characterized by: be 17 upper limb or have hard work bar slotted hole 16 on the axle clamp 3 down at magnetic separator magnetic, in slotted hole 16 positions that magnetic system is fixed with the lower shaft clamping, in slotted hole 16 length ranges, adjust magnetic and be 17 and the distance of 7 of cylinders; Scanning district's 9 corresponding magnetic pastern branches are high magnetic groups 8, are divided into low magnetic group 6 at selected district 14 corresponding magnetic pasterns, are that the magnetic group is a stepped ramp type by height step-down gradually from scanning the corresponding magnetic in district to selected district.
The many gradients of the utility model permanent magnetism are adjustable field intensity magnetic separator can be adjusted the distance between magnetic system and the cylinder according to actual needs, changes the size of drum surface field intensity, thereby improves sorting result; Again since from scan the district to the field intensity in selected district from high to low, help improving the metal recovery rate and the concentrate grade of concentrate.
Below in conjunction with drawings and Examples the utility model is described in further detail.
Accompanying drawing 1 is the adjustable field intensity magnetic separator of the many gradients of a permanent magnetism magnetic pastern separation structure schematic diagram.Magnetic is that 17 upper limb has hard work bar slotted hole 16, the width of slotted hole 16 is corresponding with the diameter of adjusting bolt 4, when needs change the magnetic induction intensity of cylinder 7 outer surfaces, unclamp and adjust bolt 4, main shaft 1 is moved downward or upward, drive upper and lower axle clamp 2,3 downward or upward, after the distance adjustment is suitable, bolt 4 is fastening adjusting, and is 17 threading cylinders 7 again with magnetic, and at this moment the magnetic induction intensity on cylinder 7 surfaces just reduced than originally or increased.In addition, be that 17 cross section left ends are installed high magnetic group 8 at magnetic, right-hand member is installed low magnetic group 6, and the magnetic group height from high magnetic group 8 to 6 of low magnetic groups reduces gradually, and yoke 5 is processed into stepped ramp type, and is corresponding with magnetic group height change.
Accompanying drawing 2 is the utility model complete machine profile, scanning district's 9 counterparts are high magnetic groups 8, be low magnetic group 6 at selected district 14 counterparts, like this from scan district 9 to the magnetic field intensity in selected district 14 by gradient from high to low, when ore pulp feeds casing 15 from feed port 11, magnetic mineral is by cylinder 7 surface absorption, rotate with cylinder, the gangue mineral that further sub-elects weak magnetic mineral in selected district 14 and be mingled with, at concentrate mouth 13 places, the water that the concentrate of drum surface absorption is sprayed by jet water spout 12 pours the concentrate case, and is because selected district field intensity is relatively low, favourable to improving concentrate grade.Non magnetic ore is discharged from mine tailing mouth 16 by overfall 10.Because it is higher relatively to scan the field intensity in district, enters particulate magnetic mineral and the higher intergrowth of grade of scanning district 9 and be adsorbed on the drum surface again, thereby help improving the concentrate rate of recovery.
