Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
The present invention will be further described below in conjunction with the accompanying drawings:
A kind of wind magnetic internal recycle pipeline tramp iron separator as shown in Figure 1, including housing 1, housing 1 is provided with charging aperture 2, row's iron mouth 3 and slag-drip opening 4, magnetic separating system and wind sorting system it is provided with in housing 1, magnetic separating system includes the power set that the roller 5 being arranged in housing 1, the magnetic system 6 being positioned at roller 5 and driving roller 5 rotate, and roller 5 is driven it to rotate by power set, and magnetic system 6 is fixed on housing and remains static, namely roller 5 rotates, and magnetic system 6 is motionless；Wind sorting system includes air inlet 7 and the air outlet 8 being arranged on housing 1, air-flow enters the internal cavity of housing 1 from air inlet 7 and is flowed out by air outlet 8, irony is separated by magnetic separating system with non iron, and dust and light material in the irony that wind sorting system will be waited at the row's of falling into iron mouth 3 are discharged.By the alternating action of two separation systems, improve the efficiency of separation to irony material and sharpness of separation.
Further, the scraper 9 removing roller 5 remained on surface material is installed on housing 1, arrange after the end that scraper 9 is positioned at magnetic system 6 and near the end of magnetic system 6, the knife face of scraper 9 fits with the barrel of roller 5, i.e. the knife face of scraper 9 and the barrel laminating of roller 5, remove the residuals on roller 5.
Further, row's iron mouth 3 is arranged over the stock guide 10 being obliquely installed, after stock guide 10 is positioned at magnetic system 6 end and be positioned at the bottom of roller 5, stock guide 10 is fixed on housing 1 and the tilt adjustable of stock guide 10, forms, between the sidewall of stock guide 10 and row's iron mouth 3, the passage that material falls and air-flow passes through.Departing from roller 5 and leave to stock guide 10 when namely iron compound turns to magnetic system 6 end with roller 5, then to row's iron mouth 3 landing, the material at this moment left on stock guide 10 is broken up, and the dust especially wrapping up Ferrous particles may partially separate.The tilt adjustable of stock guide 10, can make to be formed between stock guide 10 and row's iron mouth 3 sidewall the passage of appropriate size.
Further, air inlet 7 is arranged near row's iron mouth 3, and air inlet 7 is positioned at the lower section of stock guide 10, and air outlet 8 is positioned at the oblique upper of roller 5 and is connected with dust arrester installation.
Further, forming reverse V-shaped structure 11 between the sidewall that row's iron mouth 3 is adjacent with slag-drip opening 4, leave gap between top and the roller 5 of reverse V-shaped structure 11, roller 5, scraper 9, stock guide 10 and housing reverse V-shaped structure 11 form the internal cavity that supply stream passes through.Namely air-flow is entered by air inlet 7, the passage formed between stock guide 10 and row's iron mouth sidewall, then the gap between reverse V-shaped structure 11 and roller 5, discharges from air outlet 8.
Preferably, the gap between top and roller 5 barrel of the reverse V-shaped structure 11 of housing is less than 30mm.Being the least gap between top and the barrel of roller 5 of the most reverse V-shaped structure 11, this gap can form a high velocity air passage when air-flow passes through.
Further, charging aperture 2 is coaxially disposed with slag-drip opening 4, and the angle α of this axis and horizontal plane is more than or equal to 45 °, and this is to make the smooth slip in housing slideway smoothly of material energy.
Further, magnetic system 6 is made up of multiple magnetic patch, and magnetic patch is along the axial arranged multiple row of roller 5, and along the circumferentially multirow of roller 5, the polarity of axial adjacent two magnetic patch of roller 5 is identical, the opposite polarity of roller 5 upper adjacent two magnetic patch of circumference.
Preferably, the cornerite of magnetic system 6 is 180 °～270 °, and blanking starting point and the cornerite scope of circumference minimum point that material is entered by charging aperture 2 are all covered by magnetic system.
Preferably, magnetic patch is rare earth permanent magnet magnetic patch.
The operation principle of the present invention is as follows:
Magnetic separating system: material to be selected is fed by the charging aperture on housing, fall in inside equipped with not rotating on the roller of magnetic system, roller is driven it to rotate with material direction by power set, irony material is attracted by the magnetic force at roller surface and rotates with roller, end in roller bottom magnetic system leaves on stock guide, dropping so that material is broken up, the dust especially wrapping up Ferrous particles may partially separate；On roller, the material of residual is removed by scraper.
Wind sorting system: roller, scraper, stock guide, the reverse V-shaped textural association of housing form the internal cavity in housing；Air-flow enters from air inlet, gap between stock guide and iron mouth sidewall, dust and light material are blown afloat, and by the blowout at a high speed of the gap between the reverse V-shaped structural top of housing and roller, fine powder is blown afloat close to roller during taking out of, and high Fe contained particle is again adsorbed onto roller surface, and is again adsorbed, leave on stock guide, form wind-force, magnetic force interior circulation sorting environment alternately；Air-flow gap between reverse V-shaped structure and the roller of housing, simultaneously can non-iron substance on pair roller barrel and include that the dust of Ferrous particles plays and brush centrifugation at a high speed.Therefore, the irony material grade finally gone out from Pai Tiekou is higher, and the dust arrester installation that fine powder is connected by gas outlet is put away, and non iron material and the lowest material of iron-holder are discharged from slag-drip opening.
In sum, present configuration design is simple, reliable, by the way of pneumatic separating and magnetic separating are combined, wind-force, magnetic force interior circulation sorting environment alternately is formed in enclosure interior, improve and select iron efficiency and select iron precision, improve the grade of the iron sub-elected so that it is can directly recycle, improve economic worth.
Embodiment described above is only to be described the preferred embodiment of the present invention; not the scope of the present invention is defined; on the premise of designing spirit without departing from the present invention; various deformation that technical scheme is made by those of ordinary skill in the art and improvement, all should fall in the protection domain that claims of the present invention determines.
