Abstract

The utility model relates to a ferrous mineral concentrating and impurity removing device, which is particularly suitable for concentration and impurity removal for sulfur residues (the residues generated in preparation of sulfur from iron pyrite by indigenous methods contain ferric oxide). The device is characterized in that a feed inlet and a discharge outlet are arranged inside a drum, a magnet is disposed on outside of the lower portion of the drum, longitudinal intermittent vanes are arranged on the inner wall of the drum, and a hopper and a scouring component are disposed inside the drum. The ferrous mineral concentrating device can carry out concentration and impurity removal for sulfur residues having impurity with larger density and internal slight magnetite, and also can carry out concentration and impurity removal for other various iron ores by adjusting pressure and volume of water flow for washing ores. Additionally, the device has the advantages of simple operation, low cost, continuous operation and no pollution to environment.

Description

Iron-bearing mineral matter selecting device

Affiliated technical field

The utility model relates to the device of the selected removal of impurities of a kind of iron-bearing mineral matter, is particularly useful for the selected removal of impurities to sulphur slag (the troilite local method is produced remaining slag behind the sulphur, contains di-iron trioxide).

Background technology

Troilite is produced remaining sulphur slag behind the sulphur, and iron content is sampled between 30-40 because impurity is slightly lighter than di-iron trioxide, so present stage selected iron powder technology all inapplicable: wet magnetic separation is inoperative to the di-iron trioxide of weak magnetic; Dry type magnetic separation is also inoperative to the sulphur slag of open-air accumulation; Increase the magnetic concentration complex process, cost is higher, so inapplicable; And gravity separation method, iron powder and impurity that jigging method and wet cleaning process are difficult to density is more or less the same separate.

And, the concentration equipment of present stage all is the top that magnet is placed selected material, the magnet absorption iron powder, not only will overcome the obstruction of medium to iron powder, also will overcome the gravity of iron powder itself, most of impurity are lighter than iron powder, be suspended in the medium than iron powder is easier, so when iron powder was adsorbed, impurity also was wrapped wherein easily, so just directly have influence on the grade of selecting iron powder.

Summary of the invention

The purpose of this utility model provides a kind of iron-bearing mineral matter selecting device to remedy the deficiency of prior art.

The technical solution adopted in the utility model is: iron-bearing mineral matter concentration equipment is characterized in that: be provided with cylinder, charging aperture and discharging opening are arranged in the cylinder, the cylinder bottom is outside equipped with magnet; Inner wall of rotary drum is being arranged the leaf bar of intermittence longitudinally; Be provided with hopper and sand washing parts in the cylinder.

The beneficial effects of the utility model are: the utility model is positioned over selected thing below with magnet, use water as selected thing medium, the impurity that is suspended in the water is not flushed away with water by the effect in magnetic field, and iron powder is adsorbed on the cylinder wall by the effect of magnetic force, goes out the water surface by the leaf band.The utility model can also come other multiple iron ore is carried out selected removal of impurities by pressure and the flow of regulating the washup current the relatively large selected removal of impurities that includes the sulphur slag of weak magnetic iron ore of impurity density.In addition, the utlity model has simple to operately, with low cost, work continuously the advantage that does not pollute the environment.

Below in conjunction with accompanying drawing, the utility model is further described by embodiment:

Description of drawings

Fig. 1 is the structural representation of the utility model embodiment;

Fig. 2 is the schematic diagram at the another one visual angle of Fig. 1;

Fig. 3 is the schematic diagram at another visual angle of Fig. 1;

Fig. 4 does not install the schematic diagram of cover plate for Fig. 1.

The ferrous mineral concentration equipment is characterized in that: be provided with cylinder 1, charging aperture 2 and discharging opening 3 are arranged in the cylinder 1, cylinder 1 bottom is outside equipped with magnet 4; Cylinder 1 inwall is being arranged the longitudinally leaf bar 5 of intermittence; Be provided with hopper 6, sand washing parts 7 and secondary sand washing parts 8 in the cylinder 1; 9 for covering plate, and 10 is bearing, and covering plate 9 is the fixture of taking root of sand washing parts 7, secondary sand washing parts 8 and a charging aperture 2; 11 is cover plate.

The specific embodiment

Embodiment:

In use, the mixture of water and sulphur slag enters cylinder inside by pipeline from charging aperture 2, flows to discharging opening 3 below cylinder 1, in this process, iron powder in the mixture is adsorbed on the inwall of cylinder 1 by magnet 4, and impurity flows out to discharging opening 3 with water, and this is a removal of impurities; Iron powder rotates upwards with cylinder 1, and is taken out of the water surface by leaf bar 5, and redundant moisture and impurity are under the slit flow between the leaf bar 5.

After iron powder rose to certain altitude, the pressure water source that the hole of sand washing parts 7 is gone out washed it, the impurity in the iron powder was swept away, to reach the purpose of secondary removal of impurities.In this process, material is also in the sphere of action of magnet 4.

Iron powder after the removal of impurities continues to roll with cylinder 1 and rises, and is washed away by the pressure water source of secondary sand washing parts 8, because this moment, has broken away from the effect of magnet 4, so iron powder is just with falling under water in the hopper 6, and from the pipeline discharge of hopper outlet.

Claims

1. iron-bearing mineral matter concentration equipment, it is characterized in that: be provided with cylinder, charging aperture and discharging opening are arranged in the cylinder, the cylinder bottom is outside equipped with magnet; Inner wall of rotary drum is being arranged the leaf bar of intermittence longitudinally; Be provided with hopper and sand washing parts in the cylinder.
