Detailed description of the invention
Embodiment 1:
In order to overcome existing Vertical Mill mill on easily there is metal enrichment, cause mill and grinding roller abrasion large, greatly reduce the problem in Vertical Mill life-span, present embodiments provide a kind of slag Vertical Mill deironing apparatus as depicted in figs. 1 and 2, comprise vertical mill casing, and be arranged on the mill 1 of vertical mill casing inside and be arranged on multiple grinding rollers 2 spaced apart above mill 1, be provided with rotation tramp iron separator between two grinding rollers 2 above described mill 1; Described rotation tramp iron separator comprises axle 3, magnet 4, cylindrical shell 5 and driving mechanism, described axle 3 is fixedly installed on the vertical mill casing of mill 1 top edges, and be provided with spacing between axle 3 lower end and mill 1, magnet 4 one end is fixed on axle 3, the other end is towards mill 1 axis, described cylindrical shell 5 is socketed in outside axle 3 and magnet 4, driving mechanism drives cylindrical shell 5 to rotate around axle 3, establish at regular intervals between cylindrical shell 5 and mill 1, this spacing is determined according to the material characteristic of the magnetic field intensity of magnet 4 and slag iron particle, makes the cylindrical shell 5 after magnetizing can adsorb iron particle in slag iron.
Wherein, the mill 1 of this slag Vertical Mill deironing apparatus, grinding roller 2, axle 3 and cylindrical shell 5 are made by metal material, make this device can not damage because of the high temperature in Vertical Mill like this.Described magnet 4 is fan-shaped permanent magnet or fan-shaped electromagnet.Mill 1 can be the wavy shaped configuration that middle high rim is low, is conducive to material like this to mill 1 edge landing, is convenient to rolling of grinding roller 2.
And as one preferred embodiment, cylindrical shell 5 is full-closed structure, magnet 4 is wrapped in cylindrical shell 5; Described driving mechanism comprises drive motors decelerator 6 and sprocket wheel chain driver group 7, sprocket wheel chain driver group 7 is connected with cylindrical shell 5, drive motors decelerator 6 provides power for cylindrical shell 5 rotates, sprocket wheel chain driver group 7 is as the transmission device of power, and cylindrical shell 5 rotates around axle 3 under the driving of drive motors decelerator 6 and sprocket wheel chain driver group 7; Drive motors decelerator 6 is arranged on outside vertical mill casing, and sprocket wheel chain driver group 7 is outside equipped with protective cover, and whole device is obtained for available protecting, can not be subject to the dust pollution of Vertical Mill.
As another kind of preferred embodiment, be all provided with rotation tramp iron separator between every two grinding rollers 2 on mill 1 in multiple grinding roller 2, such slag iron particle often rolls once with regard to magnetic separation once, and the abrasion of such slag iron to mill and grinding roller will be less.
The method for removing iron of this slag Vertical Mill deironing apparatus, specifically comprises the steps:
During vertical mill grinding material, generally can carry out magnetic separation before entering Vertical Mill, but some granule metallic irons can be consolidated with slag, are referred to as slag iron, the magnetic separation before Vertical Mill can cannot be selected.During Vertical Mill work, slag iron particle is by blanking tube 8 charging of mill 1 overcentre, and when mill 1 rotates, slag iron particle is subject to centrifugal force and outwards scatters, and slag iron particle is subject to rolling of grinding roller of vertical mill 2 and broken on mill 1, is separated into solid impurity particle and iron particle; At this moment, rotate the cylindrical shell 5 of tramp iron separator owing to being subject to the magnetic susceptibility of the magnet 4 of its inside, by iron granular absorption on cylindrical shell 5, rotate around axle 3 with cylindrical shell 5, magnet 4 is static, when iron particle rotates to mill 1 with cylindrical shell 5, when not having the region of magnet 4, cylindrical shell 5 is without magnetic, and iron particle departs from cylindrical shell 5 because of gravity, fall to outside mill 1, such iron particle can not stay on mill 1 and be subject to repeatedly rolling and denuding grinding roller 2 and mill 1 of grinding roller 2.
And for the ease of collecting iron particle, described mill 1 arranged outside has collecting bin 10; Collecting bin 10 bottom is provided with gate 9.Iron particle to fall into the iron powder collection storehouse 10 outside mill 1 after cylindrical shell 5 because gravity departs from, in collecting bin 10 iron powder collection to a certain extent after, the gate 9 of collecting bin 10 bottom can be opened by iron transfer of granules out, conveniently to collect.
In sum, this slag Vertical Mill deironing apparatus structure that the utility model provides is simple, volume is little, be convenient to install, grinding and deironing can be carried out simultaneously, effectively remove the magnetic metal in vertical mill grinding, avoid magnetic metal enrichment on mill and cause the problem of the abrasion of mill and grinding roller, improve the service life of Vertical Mill, make Vertical Mill can as steel slag grinding equipment use.
More than exemplifying is only illustrate of the present utility model, does not form the restriction to protection domain of the present utility model, everyly all belongs within protection domain of the present utility model with the same or analogous design of the utility model.
