Abstract
The utility model discloses a high-efficiency magnetic separation device for mineral aggregates containing magnetic substances. The high-efficiency magnetic separation device comprises a conveyer device, a magnetic separation device and a washing device, wherein the conveyer device comprises a drive roll (2), a guide roll (1) and a conveyer belt (3) arranged between the drive roll (2) and the guide roll(1); and a roller (4) and the magnetic separation device (5) are arranged below the conveyer belt (3), and the washing device(6) is arranged above the conveyer belt (3). The high-efficiency magnetic separation device provided by the utility model adopts a technical scheme combing magnetic separation and washing, removes harmful impurities in burnt ore, improves iron quality, solves the problems that the recovery ratio is low when the burnt ore is adopted for manufacturing iron refined flour, the washing effect is poor, and the refined flour quality is lower, thereby obtaining high-quality magnetite concentrate. The high-efficiency magnetic separation device provided by the utility model is suitable for a technology combining a chemical method and a magnetic separation method for producing magnetite concentrate.
Description
Technical field
The utility model belongs to material screening installation technical field, is specifically related to a kind of efficient concentration equipment that contains the magnetisable material mineral aggregate that can expeditiously the impurity in the smart powder of iron be separated.
Background technology
China produces the smart powder of iron to sulfate slag and generally adopts magnetic separation-gravity treatment or magnetic separation in the prior art---and technologies such as gravity treatment associating flotation are carried out sorting; But because sulfate slag is through after the above PROCESS FOR TREATMENT; Arsenic, copper, phosphorus and other objectionable impurities in the smart powder of iron can't be removed, thereby influence the quality of the smart powder of iron.And prior art processes is complicated, and equipment investment is bigger, and equipment material is had relatively high expectations, and material concentration is changed responsive.For this reason, need a kind of efficient concentration equipment that contains the magnetisable material mineral aggregate that can expeditiously the impurity in the smart powder of iron be separated of exploitation.
The utility model content
It is a kind of simple in structure that the purpose of the utility model is to provide, and working stability is reliable, the efficient concentration equipment that can the impurity in the smart powder of iron be separated.
The purpose of the utility model is to realize like this; Comprise transport, concentration equipment and wash mill; Described transport comprises drive roll, guide pulley and setting thereof conveyer belt between the two; Described conveyer belt below is provided with carrying roller and concentration equipment, and the top of described conveyer belt is provided with wash mill.
The technical scheme that the utility model adopts magnetic separation, washing to combine is removed the objectionable impurities in the sulfate slag, improves the iron grade; The rate of recovery is lower when having solved sulfate slag production iron essence powder; Clean result is poor, the low problem of the smart grade powder of iron, thus obtained the smart powder of high-quality iron.The utility model combines applicable to chemical method, magnetic method and produces the smart powder craft of iron.
Description of drawings
Accompanying drawing is the overall structure sketch map of the utility model.
Among the figure: 1-guide pulley, 2-drive roll, 3-conveyer belt, 4-carrying roller, 5-concentration equipment, 6-wash mill.
Specific embodiments
Below in conjunction with accompanying drawing and embodiment the utility model is further described, but never in any form the utility model is limited,, all fall into the protection domain of the utility model based on any conversion that the utility model training centre is done.
Shown in accompanying drawing; The utility model comprises transport, concentration equipment and wash mill; Described transport comprises drive roll 2, guide pulley 1 and conveyer belt 3 between the two is set; Described conveyer belt 3 belows are provided with carrying roller 4 and concentration equipment 5, and the top of described conveyer belt 3 is provided with wash mill 6.
Described concentration equipment 5 is for being distributed in conveyer belt 3 belows, the permanent magnet between the carrying roller 4.
Described guide pulley 1, drive roll 2 are the line with rubber cylinder.
Described carrying roller 4 is the line with rubber carrying roller.
Described conveyer belt 3 is band shirt rim flat belt.
The inclination angle that is provided with of described conveyer belt 3 is 10 ~ 25 °.
The magnetic field intensity of described concentration equipment 5 is 1400～1700GS.
Described wash mill 6 comprises cleaning solution carrier pipe and spray equipment.
The washing coverage of described wash mill 6 is 1.0 ~ 1.5m.
The pipeline speed of described conveyer belt 3 is 0.6 ~ 1.0m/s.
Be the operation principle and the course of work of example explanation the utility model below with the sulfate slag:
Sulfate slag carries out pickling with sulfuric acid, then through transforming, get into behind the dispersing technology middle part of magnetic separation washing belt, after material gets into the belt middle part, under the repeatedly strong magnetic action of permanent magnet, the magnetic thing is adsorbed on the belt and moves with belt and annotate discharge end and walk.The magnetic thing is repeatedly washing away through washings near discharge end, and washing separates weak magnetic material, namagnetic substance or other harmful acrobatics with the magnetic thing.Namagnetic substance or other objectionable impurities flow into the wastewater collection pond with the many strap end of washings; The magnetic thing moves toward head (driving wheel end) with belt, under the effect of material scraper and flushing water, breaks away from belt after the magnetic regions of disengaging permanent magnet and gets into the smart powder kitchen sink of iron.Want the smart powder of utility model patent and other magnetic separation legal system iron to compare, technological process is simple, and operation is directly perceived, convenient, corrosion-resistant, and the iron powder rate of recovery is high, and clean result is better, and the smart powder of iron can be through repeatedly magnetic separation, steady quality after the continuous washing.Overcome magnetic separator to material concentration is responsive, the rate of recovery is low, impurity is higher deficiency.Iron content >=60% after this method is handled, the rate of recovery >=90% reduces production costs.
