Abstract
The utility model discloses a mechanical means for recovery of magnetic iron from tailings which is driven by a transmission system, comprising a plurality of magnetic circular disks. A discharging system formed by a material scraping plate is arranged among the circular disks. The discharging system is used for recovering the ingredients of the magnetic iron in the tailings, the recovery efficiency is high, and the ferruginous grade can reach 30%. Iron ore concentrate with the grade of more than 60% can be obtained through further grinding and magnetic separation.
Description
The utility model relates to uses the magnetic separation solid matter, is specially a kind of mechanical device that reclaims Armco magnetic iron composition wherein with magnetic force from mine tailing.
China's mine magnetic concentration working is subjected to the restriction of present technique of preparing, still the Armco magnetic iron composition that contains 4-5% in the mine tailing of discharging can not get reclaiming and drains with mine tailing, this is a tremendous loss, the iron that this part if can be lost reclaims and reaches the grade requirement of blast furnace process after further mill selects, simultaneously rationally feasible economically, will produce remarkable economic efficiency undoubtedly.Before this, domesticly once attempted directly to reclaim this part Armco magnetic iron with the drum magnetic separator that generally uses at present, this magnetic separator is to drive a large cylinder that rotates by transmission system in the groove of ore deposit, and cylindrical shell is around axle center and fixed magnetic pole rotation, uses water as discharge system after forwarding non-magnetic region to.Section between the cylindrical shell of this machine and the ore deposit groove is 0.06-0.08m only
2Reclaim Armco magnetic iron with it from mine tailing, because tailings concentration is low, ferrous grade is low again, flow is big, so recovery operation efficient is very low, from mine tailing, reclaimed 50,000 tons of Armco magnetic irons, and needed φ 750 * 1800 drum magnetic separator 10-15 platforms approximately in 1 year, invest nearly 400,000 yuan, and complex process, organization of production is huge, loses more than gain economically.
The purpose of this utility model provides a kind of simple in structure, and is easy for operation, reclaims Armco magnetic iron efficient height from mine tailing, and counter investment is few, economically feasible mechanical device.
Ferromagnetic mechanical device also is made up of the magnetic mechanism of transmission system and its drive and discharge system three parts in the recovery mine tailing of the utility model design.Be characterized in that said magnetic mechanism is to be fixed on the power transmission shaft and the magnetic disk of parallel distribution at interval, this disk is made of stainless steel disc shell parcel permanent magnet block; Said discharge system is made of the material scraping plate of fixed in position between above-mentioned magnetic disk, and this material scraping plate is manufactured with nonmagnetic substance, its cross section forming V-shape, and two edges contact with the card of magnetic disk, dash the material water pipe along being provided with in its inner groove.
The thickness of the magnetic disk sheet number of this device, its diameter dimension, magnitude of field intensity, dish all can be according to the on-the-spot flexible design of different uses with spacing.
Accompanying drawing is depicted as an embodiment of the present utility model.This device has ten magnetic disk.Fig. 1 is its installation diagram, and Fig. 2 is along Figure 1A-A cutaway view.1 is tail-box among the figure, and 2 are the mine tailing slurry, and 3 for adjusting the adjustment cover of magnetic disk spacing, 4 is end cap, and 5 is axle cap, and 6 is power transmission shaft, 7 is bearing, and 8 is bearing block, is fixed by bolts on the tail-box, 9 is material scraping plate, adds the stainless steel collet with rubber and manufactures, and by the tether of being manufactured by the nonmagnetic substance copper wire 10 it is suspended on the support 13,11 is the dish shell of magnetic disk, its diameter 1.6m, thick 40mm is equipped with many group permanent magnet blocks 12 in the shell, adjacent two magnetic disk spacings are 80mm, magnetic field intensity 1500 Gausses of card place, 14 is axle key, 15 is ladder axle, 16 is transmission system, 17 is discharger, joins with each material scraping plate end, and 18 for dashing the material water pipe, 19 for scanning water pipe, the material that magneticly elects with clear water flushing earlier during work is further washed non-magnetic impurity wherein off, improves its grade.Be respectively the flow direction of starching that turns to of magnetic disk among Fig. 2 shown in the arrow with mine tailing.
Use ferromagnetic mechanical device in the above-mentioned recovery mine tailing, as long as it is installed on two walls of corresponding tail-box, half card of magnetic disk is immersed in the mine tailing slurry, make the contrary that flows to of the direction of rotation of disk and mine tailing slurry after the start, adjust the rotating speed of flow velocity, flow and the disk of mine tailing slurry, make it reach best fit.The Armco magnetic iron of magnetic disk absorption is wiped off by material scraping plate after scanning the water pipe flushing, and water is rushed in into discharger and collected, and enters down the road Grinding procedure, manipulates very convenient.
Said apparatus is through testing at this steel torticollis mountain iron ore beneficiating factory, and the result is as follows: mine tailing iron content average grade 5.19%, 1 rev/min of magnetic disk rotating speed, mine tailing flow velocity 0.8 meter per second, flow 40m
3/ hour, one table apparatus reclaims 7.06 tons/hour of Armco magnetic irons, grade 30.15%, the rate of recovery＞60%, work continuously, 1 year recyclable Armco magnetic iron is more than 50,000 tons, and these Armco magnetic irons utilize existing magnetic separation with the choosing of regrinding of ball mill and magnetic separator, the final iron concentrate grade that obtains reaches 63%, satisfies the blast furnace process requirement fully.50,000 tons of Armco magnetic irons finally can obtain 20,000 tons of iron ore concentrates, remove cost and can make a profit more than 1,000,000 yuan, ten thousand yuan of this device unit cost 10-15 are together with more than 50 ten thousand yuan of the mill optional equipment gross investments at rear portion, operation need not 1 year is recoverable fully invested, is fully feasible economically.
