Abstract
The utility model provides a magnet ore-magnet superposition gangue-removing ore dressing device; a magnetic with the upper part being a conical body and the lower part being a column body is arranged at the middle part of a conical water chute; a finished-ore washing water pipe and a gangue washing water pipe are arranged surrounding the magnet; a cofferdam is arranged at the periphery of the upper part of the water chute; and the lower part of the water chute is provided with a finished-ore collection pipe. The ore-dressing device of the utility model adopts the original conical water chute and the ore feeding pipe, thereby being free from the addition of more parts, and having less investment and rapid effectiveness; the magnet is simple to be produced, and is convenient to be installed, and is convenient to be maintained and replaced; the ore-dressing device has reasonable structural design, and realizes the double function of the water chute, and combines the magnetic dressing and the repeat dressing of the ore, thereby favoring the removal of the gangue, and can greatly improve the grade of the finished ore and the recycling rate of the iron.
Description
Technical field
The utility model belongs to iron and steel industry preparation equipment field, relate to specifically a kind of be used for that the magnetite powder magnetic separation combines with gravity preparation take off the tail ore-dressing plant.
Background technology
Magnetic iron ore is the bigger a kind of iron ores of China's reserves distributed more widely, and particularly in the surrounding area of the Anshan, Liaoning Province in China most important iron ore place of production, the iron ore deposit of being contained almost all is a magnetic iron ore.Because the main component of magnetic iron ore is Fe
3O
4, the grade of iron is lower in addition, can not smelt directly into stove, therefore must carry out fragmentation and screening to the ore of extraction, so that reject the mine tailing impurity in the breeze.Present beneficiation method is to utilize the characteristic employing gravity floatation of the proportion of iron greater than impurity mostly, though magnetic iron ore equipment in the process of sorting is comparatively simple, easy to operate and control, but its defective is owing to be simply equipped, make the concentrate grade after the flotation on the low side, and the content of iron is higher in the mine tailing, causes the rate of recovery of iron ore concentrate relatively low.
Summary of the invention
The purpose of this utility model is exactly in order to overcome above-mentioned defective, makes full use of the higher characteristics of magnetic iron ore magnetic, provides a kind of magnetic force and gravity to close choosing, effectively removes the separator of mine tailing, raising concentrate grade.
For this reason, the technical solution taked of the utility model is:
Magnetic iron ore magnetic overlaps choosing and takes off the tail separator, comprises mineral-feeding pipe and tank, is characterized in being provided with in the middle of the taper tank magnet, is respectively arranged with concentrate water pipe and the mine tailing water pipe that pours down that pours down around magnet, and the tank top periphery has the cofferdam, and the bottom is provided with the concentrate collecting pipe.
The structure of described magnet is to stud with permanent magnet block in the outer cover of steel plate of sealing.
Described magnet is divided into two parts up and down, and top is cone, and the bottom is a cylinder.
The beneficial effects of the utility model are;
Because the utility model utilizes original taper tank and mineral-feeding pipe, therefore need not increase more polygamy spare, small investment, instant effect; Magnet is made simple, and is easy for installation, is convenient to safeguard and change; Whole separator reasonable in design has realized that a groove is dual-purpose, and magnetic separation combines with gravity treatment, and the favourable tail that takes off can greatly improve the rate of recovery of concentrate grade and iron.
Description of drawings
Accompanying drawing takes off tail separator three-dimensional structure diagram for magnetic iron ore magnetic overlaps choosing.
Among the figure: 1 is mineral-feeding pipe, and 2 is magnet, and 3 for the taper tank, and 4 is the tank cofferdam, and 5 are the concentrate water pipe that pours down, and 6 are the mine tailing water pipe that pours down, and 7 is the concentrate collecting pipe, and 8 is the concentrate flow gauge tap.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
By accompanying drawing as seen, the utility model magnetic iron ore magnetic overlaps choosing, and to take off the tail separator be by mineral-feeding pipe 1, magnet 2, taper tank 3, and tank cofferdam 4, pour down water pipe 6, concentrate collecting pipe 7 and concentrate flow gauge tap 8 of the concentrate water pipe 5 that pours down, mine tailing formed.With taper tank 3 back cut diameters is that ￠ 3m, height are that 3m is an example.
At first, select the moderate steel plate of a thickness, the top that bends and be welded into sealing is that cone, bottom are the magnet 2 that cylinder, inside stud with permanent magnet block, and the circular cone height is 1m, and cylinder diameter is ￠ 1.5m, the high 250mm of being.
Secondly, adopt the cross posture to weld together magnet 2 and taper tank 3 in the centre of taper tank 3 and with the position of taper tank 3 same sagging axis.The height of magnet 2 should make its top conical section that 1/2 upper edge that is lower than taper tank 3 is arranged.
At last, install concentrate water pipe 5 and the mine tailing water pipe 6 that pours down that pours down respectively, leave cofferdam 4, use as draining mine tailing in the top periphery of taper tank 3 around magnet 2.The awl back welding connects concentrate collecting pipe 7 in the bottom of taper tank 3, and connects upward concentrate flow gauge tap 8, reclaims so that will amass in the concentrate of taper tank 3 bottoms.The utility model is promptly accused and is completed.
Operation principle of the present utility model is: the raw ore ore pulp after the pulverizing is discharged into the top of magnet 2 through mineral-feeding pipe 1, and under the gravity effect along the slippage downwards of the cone on magnet 2 tops surface, the crystalline particle that wherein has the iron of magnetic will be attracted to the surface of taper magnet 2, and constantly feeding and the self gravitation effect along with the raw ore ore pulp, slide into the bottom of magnet 2 down along taper magnet 2 surfaces, under concentrate pours down the percussion and self gravitation effect of water under high pressure of water pipe 5 ejection, the crystalline particle of iron will fall into the bottom of taper tank 3 and collect, and flow out along concentrate collecting pipe 7.When the raw ore ore pulp constantly feeds taper magnet 2 surfaces, gangue particle wherein is not because of having magnetic, so can not adsorb mutually with the taper magnet and slip into along with the ore pulp that constantly feeds in the water body of taper tank 3, and be suspended in pulp-water top, mine tailing pour down water pour down the effect under, cofferdam 4 along taper tank 3 tops overflows outside the groove, thereby separates with cell body.
