Abstract

The utility model discloses a magnetic separator for mineral dressing in mine, which is mainly composed of a power system, an unloading scraping plate 5, a circular magnetic cylinder 6, a groove body7, a stander 8, a finished ore box 12 and an ore supply box 15, wherein the power system consists of a reducer 1, a motor 2, a coupler 3, a bearing and a bearing holder 4. The circular magnetic cylinder 6 is installed on the stander 8 through the bearing and the bearing holder 4 and is driven by the power system to rotate. The groove body 7 is arranged below the circular magnetic cylinder 6, and the finished ore box 12 and the ore supply box 15 are respectively installed at two sides of the groove body 7. One side of the groove body 7 is provided with a scouring water pipe 16, and a tailing outlet 10 is arranged below the groove body 7. The upper part of the finished ore box 12 is connected with the unloading scraping plate 5, and a finished ore outlet 9 is arranged below the finished orebox 12. The cylindrical surface of the circular magnetic cylinder 6 is divided into a by-selection area 19, a main selection area 18, a scouring transporting area 14 and an unloading area 20, and thestrength of the magnetic field of the four areas is gradually reduced. The magnetic separator has the advantages of high magnetic separation efficiency and energy conservation.

Description

Magnetic separator
One, technical field
The utility model relates to a kind of mining machinery, is mainly used in selected in the ore dressing, is applicable to two sections, three sections and concentrate selected ore dressing.
Two, background technology
In present prior art, traditional magnetic separator mainly is made up of frame, confession ore deposit case, discharging water pipe, circle magnetic cylinder body, cell body, last person's passage, stripper, concentrate case, decelerator, bearing and bearing block, shaft coupling, motor etc.Mineral aggregate is fed to the ore deposit case by ore supplying tube, from flowing in the cell body for the ore deposit case, in cell body, absorption by magnetic thing piece in the circle magnetic cylinder body is adsorbed on the cylinder surface with magnetic material, and cylinder rotates under the drive of transmission mechanism, be transported to the stripper position with being adsorbed on its surperficial magnetic material, by the absorption that do not have magnetic thing piece and free discharging, water dashes and unloads simultaneously, and what have uses the scraper plate discharging.The shortcoming of this magnetic separator: the one, discharging is unclean, and has the small part material to flow downstream into cell body by the gap of stripper and cylinder all the time, causes the reduction of operating efficiency.The 2nd, use the scraper plate discharging, discharging is clean, but the disk pack angle is less than normal, has the part material not to be transported to the stripper position all the time, just past the backflow, the situation that causes magnetic separation repeatedly to reflux repeatedly, the operating efficiency of magnetic separator is lower, consumed electric energy, last person's grade is higher, causes the waste of mineral resources.
Three, utility model content
It is wide that the purpose of this utility model provides a kind of adaptation ore, and the efficiency of magnetic separation height is at the bottom of last person's grade and the magnetic separator of energy savings.
Dynamical system that the utility model magnetic separator mainly is made up of decelerator, motor, shaft coupling, bearing and bearing block and drain separator, circle magnetic cylinder, cell body, frame, concentrate case, form for the ore deposit case.The circle magnetic cylinder is installed on the frame by bearing and bearing block, by the dynamical system driven rotary.The below of circle magnetic cylinder is a cell body, and the both sides of cell body are separately installed with the concentrate case and for the ore deposit case, a side of cell body is equipped with wash tub pipe, and there is the tailing outlet below of cell body.Concentrate case top and drain separator join, and there is the fine fodder outlet below of concentrate case.The cylinder type surface of circle magnetic cylinder is divided into by-election district, main separation district, flushing traffic zone and discharge zone, and the magnetic field intensity in four districts weakens successively.
The central angle of by-election district, main separation district, flushing traffic zone and discharge zone correspondence is preferably 50-80,60-80,80-120 and 80-170 successively, and magnetic field intensity is preferably 240-280mT, 180-240mT, 160-190mT and 0 successively.
Adopted technique scheme, mineral aggregate is supplied with by ore supplying tube road system, through flowing into cell body for the ore deposit case.The circle magnetic cylinder rotates under the drive of power drive system, and the most of magnetic material in the cell body is attracted to round magnetic cylinder outer surface in the main separation district, and along with the rotation of circle magnetic cylinder is shifted out, is transported to the drain separator place, is scraped in the concentrate case.The weakly magnetic material that small part is not selected is adsorbed in strong magnetic by-election district and selects.The residue mineral water forms the last person from the overflow of overflow narrow orifice.In the magnetic separation workspace of circle on the magnetic cylinder, to magnetic material, no matter the magnetic power all can be adsorbed and be selected.Efficiency of magnetic separation height like this, discharging is clean, and last person's grade is low, does not exist to be selected material and to form and pass back into the cell body phenomenon, and can suitably reduce water, has improved the synthetic operation efficient of magnetic separator, has saved the energy.
Four, description of drawings
Fig. 1 is the structure chart of the utility model magnetic separator,
Fig. 2 is the utility model magnetic separator cross-sectional configuration figure.
Five, the specific embodiment
Below in conjunction with the drawings and the specific embodiments the utility model is further described.
In Fig. 1 and Fig. 2, dynamical system that the utility model magnetic separator mainly is made up of decelerator 1, motor 2, shaft coupling 3, bearing and bearing block 4 and drain separator 5, circle magnetic cylinder 6, cell body 7, frame 8, concentrate case 12, form for ore deposit case 15.Circle magnetic cylinder 6 is cylindrical steel cylinders of a hollow, and two ends in cylinder interior, go out a fan-shaped brandreth by the central shaft circumferentially extending by end cap seal, on the brandreth surface, is fixed with from level to level magnetic thing piece with bolt, and magnetic thing piece outer surface tightly wraps up with galvanized iron sheet.Circle magnetic cylinder 6 is installed on the frame 8 by bearing and bearing block 4, by the dynamical system driven rotary.The below of circle magnetic cylinder 6 is cell bodies 7, and the both sides of cell body 7 are separately installed with concentrate case 12 and supply ore deposit case 15.One side of cell body 7 is equipped with wash tub pipe 16, and there is tailing outlet 10 below of cell body 7.Concentrate case 12 tops and drain separator 5 join; There is fine fodder outlet 9 below of concentrate case 12.The magnetic field intensity that the cylinder type surface of circle magnetic cylinder 6 is divided into by-election district 19, main separation district 18, flushing traffic zone 14 and 20, four districts of discharge zone weakens successively.
The corresponding circular arc in big or small Yi Ge district of by-election district 19, main separation district 18, flushing traffic zone 14 and discharge zone 20 right central angle (also crying the disk pack angle) represent, be preferably 50 °-80 °, 60 °-80 °, 80 °-120 ° and 80 °-170 ° successively, magnetic field intensity is preferably 240-280mT, 180-240mT, 160-190mT and 0 successively.
