Abstract

The utility model discloses a magnetic separator for iron-ore dry powder. A plurality of consecutively connected magnetic separation devices are arranged on a frame, and Each magnetic separation device comprises a magnetic separation roller and a material flowing plate; the magnetic separation roller is formed by the way that a fixed shaft is arranged on the frame, a rotary drum is connected with the fixed shaft through a bearing, an electromagnet with a sector-shaped cross section is arranged on the fixed shaft inside the rotary drum in the axial direction, and a controller is electronically connected with the electromagnet and the rotary drum; an axial ledge is arranged on the surface of the rotary drum; the material flowing plate is a curved plate and arranged on the outer side of the rotary drum, and opposite to the electromagnet; and a feed deflecter is arranged at the top end of the material flowing plate, and an iron-powder discharge belt is arranged below the magnetic separation roller. By utilizing the magnetic separator for iron-ore dry powder provided by the utility model, the problem that the mine is difficult to exploit in a droughty and water shortage area can be solved, the qualified iron refined powder with the grade of more than 66% can be gained, and the recovery rate can be increased to more than 80%.

Description

A kind of iron ore dry powder magnetic separator
Technical field
The utility model relates to a kind of iron ore separation equipment, specifically a kind of iron ore dry powder magnetic separator.
Background technology
In the existing iron ore wet separation technology, though wet magnetic separation can reach specification requirement, the place that it requires factory to be based upon to have abundant water resources, and, then can't use wet magnetic separation to obtain the smart powder of high-precision iron for the mine district of lack of water.
The utility model content
The purpose of this utility model will provide a kind of iron ore dry powder magnetic separator exactly, to solve the difficult problem of drought and water shortage area development of mines.
The utility model is achieved in that
Iron ore dry powder magnetic separator of the present utility model is that frame is provided with some concentration equipments that join in regular turn; Described concentration equipment comprises magnetic separation roller and logistics plate; Described magnetic separation roller is that frame is provided with dead axle, is connected to cylinder by bearing on dead axle, and it is fan-shaped electromagnet that the dead axle in the cylinder is provided with the cross section, and electromagnet is electrically connected with controller; Be provided with axial fin at cylinder surface; Described logistics plate is an arc, is arranged on the cylinder outside, and is relative with described electromagnet, is provided with the charging baffle plate on described logistics plate top; Below described magnetic separation roller, be provided with iron powder and go out strip.
Because the electromagnet of this magnetic separator can be regulated and control the magnetic field power by controller, therefore, magnetic field intensity can satisfy it fully all can realize requirement that iron powder is adsorbed to various breezes of different nature under contactless state.The logistics plate of iron ore dry powder magnetic separator of the present utility model setting is an arc, be arranged on the cylinder outside, relative with described electromagnet, this arcuation logistics plate can make the breeze and the electromagnet that flow through that more closely adsorption time is arranged, thereby has improved the absorption property of this magnetic separator.
Adding has been milled to 100 purpose iron ore dry powder to iron ore dry powder magnetic separator of the present utility model from logistics plate top, and the charging baffle plate that is provided with on logistics plate top can guarantee that Iron Ore Powder can not fall within on the cylinder of magnetic separator.Last step supplied materials is a dry powder, have loose, NA characteristics, in the process of hanging, iron powder in the Iron Ore Powder is adsorbed between the fin of cylinder surface and rotation thereupon by the magnetic field that electromagnet produced, when going to the below, iron powder falls under the gravity effect, goes out strip via the iron powder below the magnetic separation roller and sends.In the process that Iron Ore Powder hangs downwards, useless husky because not adsorbed by magnetic force, directly fall and, enter the next stage concentration equipment along under the logistics plate current, begin next magnetic separation process.Iron ore dry powder magnetic separator of the present utility model comprises the level Four concentration equipment that sets gradually, and can obtain grade up to the smart powder of 66% qualified iron, and the rate of recovery is increased to more than 80%.
Description of drawings
Fig. 1 is the structural representation of iron ore dry powder magnetic separator of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, described dry powder magnetic separator is that frame is provided with the concentration equipment that level Four is joined in regular turn; Described concentration equipment comprises magnetic separation roller and logistics plate; Described magnetic separation roller is that frame is provided with dead axle 4, is connected to cylinder 5 by bearing on dead axle 4, and being provided with the cross section on the dead axle in cylinder vertically is fan-shaped electromagnet 3, and electromagnet and cylinder are electrically connected with controller; Cylinder is by the actuating unit driven rotary. and the rotary speed of cylinders at different levels should be regulated and control respectively, is fit to ore in sand form of different nature thereby match with the magnetic field intensity with each magnetic separation roller. be evenly equipped with axial fin 51 on cylinder 5 surfaces; Described logistics plate 2 is an arc, is arranged on the cylinder outside, and is relative with described electromagnet 3, is provided with charging baffle plate 1 on described logistics plate top; Below described magnetic separation roller, be provided with iron powder and go out strip 6.
When using magnetic separator to carry out magnetic separation, Iron Ore Powder is injected from logistics plate top, and charging baffle plate 1 can guarantee that Iron Ore Powder can directly not fall within on the cylinder 5, in order to avoid reduce the grade of iron powder.In the Iron Ore Powder dropping process, iron powder is drawn to cylinder surface by the magnetic field that electromagnet produces, and falls within iron powder under in the cylinder rotation process to go out on the strip.The Iron Ore Powder that is not adsorbed then flows into the next stage concentration equipment via logistics plate 2, carries out the next stage magnetic separation.Through after the continuous level Four magnetic separation, Iron Ore Powder iron powder select step by step, remaining tail sand goes out through afterbody logistics plate current.After collecting, this dry powder shape tail sand can be used for making non-burning brick, also can be used for recovering landforms.
