Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than the embodiment of whole.It is based on Embodiment in the present invention, it is all other that those of ordinary skill in the art are obtained under the premise of creative work is not made Embodiment, belongs to the scope of protection of the invention.
As depicted in figs. 1 and 2, a kind of slag horizontal roller mill deironing apparatus, including cylinder 1, Yi Jishe are present embodiments provided Stock guide 3 inside cylinder 1, pressure roller 5 and material scraping plate 7 are put, wedge shape space is formed between the pressure roller 5 and the side wall of cylinder 1, institute State stock guide 3 and cylinder 1 axially to arrange into certain inclination angle, the material scraping plate 7 is fixedly installed in cylinder 1, and with cylinder 1 in Sidewall contact, material scraping plate 7 is located at the top of stock guide 3, and nonmagnetic cylinder 2, institute are provided between the material scraping plate 7 and stock guide 3 State and a permanent magnet 4 is fixedly installed inside nonmagnetic cylinder 2, the lower section of the nonmagnetic cylinder 2 is provided with for collecting nonmagnetic rolling Adsorb the iron recovering mechanism 6 of iron on cylinder 2.
Wherein, the nonmagnetic cylinder 2 is high temperature resistant stainless steel material, and stock guide 3, scraper plate 7 and pressure roller 5 are also by resistance to High temperature metallic material is made, so that the device will not be damaged because of the hot environment in horizontal roll grinding cylinder.The iron is returned Receipts mechanism 6 is conveying worm, is connected with outside cylinder 1, in time the iron adsorbed on nonmagnetic cylinder 2 can be delivered to into cylinder Outside 1.Tilt adjustable between the stock guide 3 and the axial direction of cylinder 1, its angle of inclination according to except after iron slag in cylinder In falling position be designed adjustment so that slag can Jing roll for many times, repeatedly except iron.
And as one kind preferred embodiment, the nonmagnetic cylinder 2 adopts full-enclosed structure, permanent magnet 4 to wrap up In nonmagnetic cylinder 2, the nonmagnetic cylinder 2 is connected with the external motor of cylinder 1, by its rotation of Motor drive, the nothing Magnetic pulley 2 is with the rotation direction of cylinder 1 conversely, the transfixion in nonmagnetic cylinder 2 of permanent magnet 4;The permanent magnet 4 is arc Structure, the side fallen near slag is arranged, and covers the nonmagnetic partial sidewall of cylinder 2;The outer surface of nonmagnetic cylinder 2 is circumferentially etc. Spacing is provided with striker plate 8;Slag is scraped in falling process by material scraping plate 7, and iron particle is subject to the magnetic of parcel permanent magnet 4 in slag Property attract and adsorb on the surface of nonmagnetic cylinder 2, striker plate 8 takes away the iron particle of absorption forever when nonmagnetic cylinder 2 rotates The magnetic-adsorption scope of magnet 4, the charging aperture of the iron recovering mechanism 6 has the part of permanent magnet 4 and nothing positioned at nonmagnetic cylinder 2 The underface of permanent magnet part intersection, losing the iron particle of the magnetic-adsorption of permanent magnet 4 can all drop to iron recovering mechanism 6 In.
The method for removing iron of the slag horizontal roller mill deironing apparatus, detailed process is as follows:
Cylinder 1 rotarily drives slag and rolls slag iron into the wedge shape space that cylinder 1 and pressure roller 5 are formed and is separated into thin of slag Grain;Then, adhere to after rolling the slag fine grained of the side wall of cylinder 1 separate with the side wall of cylinder 1 through the scraper of top material scraping plate 7 and Fall, now the more slag iron particle of the iron particle or iron content in slag fine grained be subject to parcel permanent magnet 4 magnetic attract and The surface of nonmagnetic cylinder 2 is adsorbed in, nonmagnetic cylinder 2 rotates and for the more slag iron particle of iron particle or iron content to take away permanent magnet 4 magnetic-adsorption scope and fall, the more slag iron particle of the iron particle or iron content fallen falls into the iron recovering mechanism 6 of bottom and enters And be delivered to outside cylinder 1.
And it is preferred, slag in cylinder 1 can through repeatedly rolling, scraper, iron removal, roll once just except once Iron, makes slag in grinding process except iron is more thorough.The number of times that it is rolled can be by adjusting the guide angle of stock guide 7 come real It is existing, often roll once, the angle of a stock guide 7 is adjusted, the drop point for falling slag is made from stock guide 7 to discharge zone close Set a distance, the final slag except after iron falls into discharge zone from stock guide 7.
In sum, the present invention is provided this slag horizontal roller mill deironing apparatus simple structure, small volume, are easily installed, Grinding can simultaneously be carried out with iron is removed, can effectively remove the magnetic metal body in horizontal roller mill grinding, it is to avoid magnetic metal body is enriched with And the abrasion of cylinder and pressure roller is caused, improve its service life;
Outer circulation is compared except iron greatly reduces the abrasion of equipment, plant maintenance amount is reduced, so as to reduce maintenance cost.
Exemplified as above is only the illustration to the present invention, does not constitute the restriction to protection scope of the present invention, all It is that design same or analogous with the present invention is belonged within protection scope of the present invention.
