Abstract
The utility model belongs to a dressing device, which relates to a magnetic reselect device for concentrating magnetite-a magnetic dressing column. The magnetic dressing column comprises a feed hopper, a feed pipe, an overflow trough of the gangue, an upper separation cylinder, an upper excitation coil, an upper coat, a water pipe, a lower excitation coil, a lower coat, a lower separation cylinder, a discharge material valve of the ore concentrate and an electric control cabinet. The magnetic dressing column is characterized in that the separation cylinders, the excitation coils and the coats are composed of the upper set and the lower set; the upper and the lower excitation coils are arranged at the outside of the upper and the lower separation cylinders; the excitation coils are supplied electricity by the program-controlled electric control cabinet which is connected with the excitation coils; the polarities of the excitation coils are consistent, or the polarities of 1-2 sets of the excitation coils are opposite. The utility model has the advantages of high precision of separation and high rate of production of ore concentrate work, and the mine needing is coarse compared with the whetting mine. The magnetic dressing column can be used to get the final concentrate with qualified grade in advance from the middle products of magnetic dressing and the high grade concentrate through concentrating the low grade concentrate from the magnetic dressing plant. The magnetic dressing column can be used to concentrate the ore concentrate of the easy choosing magnetite to get the super iron ore concentrate.
Description
Technical field
The utility model belongs to a kind of preparation equipment, relates to a kind of magnetic gravitational separation equipment that is used for selected magnetic iron ore---magnetic separation post.
Background technology
At present, the permanent-magnet drum type magnetic separator that domestic magnetite separation factory uses, there is powerful magnetization magnetic coagulation in its magnetic field intensity than higher.The magnetic force sloughing-off tank is that a kind of magnetic gravitational separation equipment is the stationary magnetic field owing to it, and the ascending current speed of permission is little, can only tell sludge and fine-grained gangue and part particulate intergrowth.Drum magnetic separator and magnetic force sloughing-off tank, their major function are to tell qualified tailings, thereby improve concentrate grade.Magnetic accumulating machine is the magnetic-gravity concentrator that permanent magnetism system is divided into the multi-turn multilayer, and its major function is to tell fine-grained gangue and particulate intergrowth.But because they all are the stationary magnetic fields, no matter what kind of pole form does changes, still in various degree the existence of the problem of magnetic coagulation parcel intergrowth and monomer gangue, and magnetic and the non magnetic problem that is mingled with can not get basic solution.The magnetite separation process is at first through broken ore grinding, ore mineral is milled to basic monomer to be dissociated, but always some iron mineral particle is the intergrowth existence, conventional preparation equipment permanent-magnet drum type magnetic separator, because magnetic field is more intense and the existence of magnetization magnetic coagulation, not only intergrowth is recycled in the concentrate, also has considerable sludge and fine-grained gangue also to be wrapped up in in the concentrate, thereby has reduced concentrate grade.The inventor is at the Chinese utility model patent ZL93228152.4 magnetic separation post of first to file, a kind of electromagnetic type magnetic gravitational separation equipment that is a sorting inner core of forming by overcoat and a plurality of magnet exciting coil, constitutes to ore discharge device and electrical control cubicles, the ascending current speed that it allows is very high, add the effect of the pulsating field that moves down again, thereby can efficiently tell intergrowth, obtain high-grade magnetite concentrate, but exist water consumption than large equipment height problem of higher.
Summary of the invention
The utility model is to the improvement in first to file magnetic separation rod structure design, and purpose is for overcoming the shortcoming of above-mentioned existence, and a kind of separation tube, the magnet exciting coil and magnetic separation post of overcoat up and down up and down of having up and down is provided.
The utility model magnetic separation post content Description:
The utility model magnetic separation post, be by: mine feeding bucket and mineral-feeding pipe, mine tailing overflow launder, go up separation tube, go up magnet exciting coil, go up overcoat, feed pipe, down magnet exciting coil, down overcoat, separation tube, concentrate ore discharge valve, electrical control cubicles constitute down, it is characterized in that: separation tube, magnet exciting coil and overcoat respectively are divided into up and down two groups form and form; Magnet exciting coil is arranged on the separation tube outside up and down up and down; The power supply of magnet exciting coil adopt connect with it can programme controlled electrical control cubicles power supply, the polarity of magnet exciting coil be unanimity or have 1～2 group opposite polarity.
The utility model magnetic separation post, its reasonable in design is compared with the magnetic gravitational separation equipment of close selected magnetic iron ore, has the sharpness of separation height, and required relative grinding particle size is thick, characteristics such as concentrate operation productive rate height.Because pulsed magnetic field that exist to change and powerful relatively rotation ascending current, so it can fully destroy magnetic coagulation, can make full use of magnetic coagulation again, thereby can efficiently tell intergrowth, increases substantially concentrate grade, improves operation productive rate and operation recovery.Available its obtains qualified grade final concentrate in advance from the magnetic separation intermediate products, the low-grade concentrate of also available its selected magneticore-dressing plant obtains the high-grade concentrate, also can be used to selected easy magnetite concentrate and obtains extraction of superpure concentrate of magnetite.
Description of drawings
Fig. 1 is a magnetic separation rod structure schematic diagram
Among the figure: 1 is that mine feeding bucket and mineral-feeding pipe, 2 are electrical control cubicles for concentrate ore discharge valve, 11 for separation tube down, 10 for overcoat down, 9 for magnet exciting coil down, 8 for feed pipe, 7 for last overcoat, 6 for last magnet exciting coil, 5 for last separation tube, 4 for mine tailing overflow launder, 3.
The specific embodiment
The utility model magnetic separation post is to realize like this, specify below in conjunction with accompanying drawing, see Fig. 1, the utility model magnetic separation post be by: mine feeding bucket and mineral-feeding pipe 1, mine tailing overflow launder 2, go up separation tube 3, go up magnet exciting coil 4, go up overcoat 5, feed pipe 6, down magnet exciting coil 7, down overcoat 8, separation tube 9, concentrate ore discharge valve 10, electrical control cubicles 11 constitute down, it is characterized in that: go up separation tube 3 and following separation tube 9, go up magnet exciting coil 4 and following magnet exciting coil 7 and last overcoat 5 and following overcoat 8 and respectively be divided into upper and lower two groups form composition.Upper and lower magnet exciting coil 4 and 7 is arranged on the outside of upper and lower separation tube 3 and 9.Can programme controlled electrical control cubicles 11 powering of connecting with it adopted in the power supply of magnet exciting coil, adopts the power supply of AC-DC order.Upper and lower magnet exciting coil 4 be consistent with 7 polarity or have 1～2 group opposite polarity.
The utility model magnetic separation post assorting room: low-grade concentrate is fed by the mine feeding bucket and the mineral-feeding pipe 1 on top, under the effect of the pulsating field that moves down, the magnetic ore particle is purified purification through the magnetic polymerization and the dispersion of repeated multiple times, at its underpart output high-grade magnetite concentrate.Monomer gangue, sludge, intergrowth, particularly lean intergrowth that the high speed ascending current will be in dispersity dash the band rising, are overflowed by mine tailing overflow launder 2 at last, realize that smart tail separates.
