Description

A kind of pair of magnetic system group done magnetic separation updraft type magnetic separator

The utility model relates to the magnetic separation of the magnetic separtor of the immobile material vehicle that conveyor type arranged of magnetite; Use the combination of the equipment that dry method that bulk material adopts separates solid from solid, be applicable to other dry type partition methods of bulk material, the separation that for example is suitable for the bulk goods that the astigmatism package material handles like that separates solid from solid; Sorting, particularly a kind of pair of magnetic system group done magnetic separation updraft type magnetic separator.

Sneak at present 5-20% barren rock in the ore extraction process, to the separation of poor magnetic iron ore; Sorting generally mostly is to adopt wet magnetic separation and do magnetic separation, be to adopt magnetic pulley to separate ore as doing magnetic separation, promptly in the adhesive tape conveyor great wheel, stud with permanent-magnet block and do magnetic separation, select the part ore, it generally is the great wheel place that magnetic pulley is arranged on the ore conveyor belts machine after the fragmentation, its magnetic effect belongs to suction mode down, be that magnet is arranged on the bottom of being inhaled ore, because inhaling ore, the effect of magnetic force on adhesive tape, is transported to next procedure with sealing-tape machine, barren rock is dished out can reach 50-60%, go into mill thereby improve, the ore ferrous grade of magnetic separation, volume increase iron ore concentrate stone is had certain effect, but ubiquity when magnetic pulley is done magnetic separation and is separated, the insufficient poor effect of sorting, form the magnetic net owing to hold ore between the magnet both positive and negative polarity, barren rock in the magnetic net is thrown and is not gone out, the barren rock of being pressed by the bottom of magnetic massive ore is also thrown and is not gone out, still be mixed among the ore, also have the barren rock of being dished out to take away the ore that part is not lived by magnetic, cause the resource loss waste, have again be invest bigger, it is less to produce effects, shortcomings such as production capacity is low, for overcoming above-mentioned existing weak point, the utility model has designed a kind of pair of magnetic system group and has done magnetic separation updraft type magnetic separator.

The purpose of this utility model provides a kind of ore magnetic separation, sorting is abundant, improve and go into mill, magnetic separation ore ferrous grade, reduce tailings grade, improve metal recovery rate, improve concentrate output, improve production capacity, can relax ore geological boundry grade to poor magnetic iron ore, increase the exploitation reserves, avoid the resource loss waste, the dried magnetic separation updraft type magnetic separator of two magnetic system's groups simple and compact for structure.

The utility model is achieved in that fuselage support is triangular in shape, at the right-hand member place of fuselage support magnetic separation master movable pulley is installed, the outside of magnetic separation master movable pulley has rolling barrel, both side ends is connected and installed with the quill cylindrical shell respectively in the front and back of rolling barrel, the quill cylindrical shell of rolling barrel two side ends lays respectively among the bearing spider of both sides, fuselage support front and back, quill cylindrical shell place's stationary fit at magnetic separation master movable pulley rolling barrel rear side is equipped with reductor, left side at reductor is equipped with motor, magnetic separation master movable pulley back shaft rear and front end is run through respectively to peg graft respectively behind the quill cylindrical shell of rolling barrel two side ends and is fixed on the fuselage support, on the inboard of magnetic separation master movable pulley rolling barrel and magnetic separation master movable pulley back shaft, the stationary cylinder body is installed, distributing on the lateral surface of the right side of stationary cylinder body, main magnetic is installed is the chunk body, main magnetic is that the chunk body is the semicircle magnetic surface of 180 degree, symmetrical counterweight block is installed on the lateral surface of the left side of stationary cylinder body, main magnetic on magnetic separation master movable pulley rolling barrel medial surface and the stationary cylinder body is that the external side of chunk has the gap, it is the chunk body that additional magnetic is installed on the left side lower fuselage support of magnetic separation master movable pulley rolling barrel, additional magnetic is that the chunk body is rectangle, the downside face that is the chunk body at additional magnetic is equipped with plane clapboard, the upside that is the chunk body at additional magnetic is equipped with fixed head, fixed head contacts with fuselage support and fixes, tail wheel and screw mandrel push-and-pull take-up are installed at the left end place of fuselage support, the two ends of tail-gear spindle lay respectively in the bearing spider on the screw mandrel push-and-pull take-up, on fuselage support, be separately installed with the bearing carrying roller, in the outside of magnetic separation master movable pulley rolling barrel, additional magnetic is the downside of chunk body plane dividing plate, on the outside of tail wheel and the bearing carrying roller around adhesive tape is installed.

The utility model ore magnetic separates, sorting is abundant, the dried mine tailing amount that choosing is fallen can reach 90-95% of ore barren rock mixed volume, improved and gone into mill, magnetic separation ore ferrous grade, reduced tailings grade, improved metal recovery rate, improved concentrate output, on inhale ore amount and bring up to more than 80-90% by 60-70%, improve production capacity more than 30%, make it near the geology ferrous grade, separate, efficiency of separation effect is obviously remarkable, can relax ore geological boundry grade to poor magnetic iron ore, the exploitation reserves have been increased, avoided the resource loss waste, invested less, it is very fast to produce effects, and production capacity is big, to greatly, in, little and old magneticore-dressing plant is all applicable, adaptability is stronger, and social benefit and economic benefit are more considerable significantly, and simple and compact equipment structure, be easy to make to install and apply advantage such as with low cost.
