Description
Technical field
The utility model belongs to dry-type magnetic extractor technical field, is specifically related to a kind of combined magnetic iron ore dry type and throws tail machine.
Background technology
Along with domestic iron and steel enterprises is to the continuous increase of smart iron powder demand, seem further important to the exploitation of iron ore of low ore grade, the chromium depleted zone of especially commute choosing develops, or even the exploitation to Ultra-low-grade magnetite.Raw iron ores is transported to after fragmentation that to select factory to carry out selected, to iron ore carry out selected before first to carry out levigate to it, if it is not high to enter to grind the grade of ore, power consume and steel directly will be caused to consume higher, and the cost of transportation of raw ore ore is also increased to some extent.The full Iron grade of chromium depleted zone is lower, so will throw useless process before poor iron ore enters mill in advance, present most chromium depleted zone mining plants magnetic pulley belt feeder carries out dry type and throws useless, also has the floated magnetic separator of part chromium depleted zone mining plants to carry out throwing and gives up.Carry out throwing with magnetic pulley belt feeder to give up, be mingled with serious, the Armco magnetic iron rate of recovery is lower; Carry out throwing in useless process for floated magnetic separator, the ferromagnetic rate of recovery increases to some extent, but because conveying belt vibration is strong not, magnetic field is continuous, the bed of material is thicker, still there is a certain amount of being mingled with, if reduce thickness of feed layer, treating capacity will reduce.
Summary of the invention
The purpose of this utility model is intended to overcome above-mentioned deficiency, provide a kind for the treatment of capacity large, throw the useless combined magnetic iron ore dry type that rate is high, concentrate grade is high, the rate of recovery is high, inclusion rates is low and throw tail machine.
For achieving the above object, the technical solution adopted in the utility model is:
Combined magnetic iron ore dry type throws tail machine, feed hopper is positioned at the front upper end of frame, feed hopper rear lower has magnet drum, be respectively equipped with one before and after below magnet drum and select tailing bin and distribution cabins, machine frame inside is provided with chute and lower chute from top to bottom, upper chute inside is provided with belt upper backup roll and is adjacent to the lower material strip of chute, combined type kicker magnet and combined type weak magnet is respectively equipped with before and after belt upper backup roll top, there is certain distance between combined type kicker magnet and combined type weak magnet and be provided with leather belt roller, lower chute inside is provided with belt roller and is adjacent to the upper material strip of lower chute, be provided with vibrating roller immediately below combined type kicker magnet and be positioned at material strip bottom on lower chute, lower chute rear end is provided with magnetic pulley, magnetic pulley bottom is provided with two and chooses ore storage bin, two choose and are provided with two from front to back successively after ore storage bin and select tailing bin and two concentrate selection storehouses, frame lower end organic block.
Described magnet drum is cylindric, and inner first half is fixed with permanent magnet, and permanent magnet does not rotate with magnet drum.
Described belt upper backup roll and belt roller are round-shaped, and length is all slightly less than belt width.
Described vibrating roller is made up of roller and roll stand, and between roll stand, angle is 120 °, and roller is cylinder roll, and vibrating roller number is 2,3 or multiple.
Described combined type kicker magnet and combined type weak magnet are the cuboid magnet of cuboid permanent magnet combination, width is all slightly less than chute blanking bandwidth, length is all slightly less than 1/3rd of chute blanking strip length, between combined type kicker magnet and combined type weak magnet, spacing is slightly larger than 1/5th of upper chute blanking strip length, combined type kicker magnet magnetic is higher than combined type weak magnet, and combined type kicker magnet is all vertical with horizontal direction with the pole orientation of combined type weak magnet.
Described leather belt roller of crossing has three round rollers to combine, and size and dimension requires identical with belt roller with belt upper backup roll.
The utility model in use, starter motor, magnet drum, upper chute, lower chute and vibrating roller is driven to rotate, magnetite ore in small, broken bits is fed feed hopper, and under the effect that magnet drum rotates, a large amount of gangue and a small amount of magnetic iron ore enter one and select tailing bin and discharge, a large amount of magnetic iron ore and a small amount of gangue become rough concentrate and enter distribution cabins, rough concentrate flows out from distribution cabins lower end and is layered on the belt of lower chute uniformly, and because the throwing in advance of magnet drum is given up, the bed of material on belt is thinner.
Rough concentrate moves backward under the rotation of lower chute, when moving to vibrating roller top, due to the upper material strip of chute under the knocking of vibrating roller discontinuity, rough concentrate is constantly loose, magnetic iron ore moves upward and is adsorbed on the lower material strip of chute under the effect of combined type kicker magnet magnetic field force, and moves backward with the lower material strip of upper chute.
Magnetic iron ore is adsorbed on the lower material strip of chute, and when the lower zone of belt pulley has been in motion, because the lower zone magnetic pole crossing belt pulley is weak, magnetic iron ore scatters on bed of material surface, and the gangue be mingled with and magnetic iron ore are loose further.
Rough concentrate continues to move backward under the rotation of lower chute, when moving to combined type weak magnet bottom, because magnetic is weak compared with combined type kicker magnet bottom, loose magnetic iron ore moves upward again under the action of a magnetic force and is adsorbed on the lower material strip of chute, and move backward with the lower material strip of upper chute, when magnetic iron ore institute magnetic field force induced be less than gravity time, magnetic iron ore depart from belt fall into two concentrate selection storehouses.
When magnetic iron ore on lower chute on material strip and gangue move rearwards to magnetic pulley place, magnetic iron ore falls into two under the action of a magnetic force and chooses ore storage bin, and gangue is thrown into two and selects tailing bin.
Advantage of the present utility model: have treating capacity large, throw the useless feature that rate is high, concentrate grade is high, the rate of recovery is high, inclusion rates is low.
