Detailed description of the invention
Below in conjunction with accompanying drawing, specific embodiment of the utility model is elaborated.
As shown in Figure 1, this iron ore magnetic plant, comprise body 1, the inner chamber of described body 1 is provided with adjacent separation chamber 2 and expansion chamber 3, the annular magnet conveyer belt 4 rotated clockwise runs through dividing plate 5 between separation chamber 2 and expansion chamber 3 and its two ends lay respectively in separation chamber 2 and in expansion chamber 3, gap is provided with between described dividing plate 5 and the surface of magnetic conveyer belt 4, the sidewall of described expansion chamber 3 is provided with vertically against the scraper plate 6 of magnetic conveyer belt end face, the bottom of expansion chamber 3 is provided with discharging opening 7, the top of described separation chamber 2 is provided with charging aperture 8, its sidewall offers dust outlet 9, the air blast 10 to up-draught is provided with bottom it.
Granular iron ore material is poured in separation chamber 2 from charging aperture 8, ferromagnetic near magnetic conveyer belt 4 is adsorbed on magnetic conveyer belt 4, and the bottom of separation chamber 2 is directly fallen to from the raw material that magnetic conveyer belt 4 is distant, blown afloat by the air blast 10 to up-draught, ferromagnetic can be blown near magnetic conveyer belt 4 and be adsorbed, non-ferromagnetic thing is then discharged from dust outlet 9, magnetic conveyer belt 4 transmits clockwise, its ferromagnetic be adsorbed onto in separation chamber 2 is sent in expansion chamber 3, through scraper plate 6 position, ferromagnetic is stopped by scraper plate 6 and is separated with magnetic conveyer belt 4, fall in the discharging opening 7 of expansion chamber 3 bottom, complete magnetic separation process.The zone face area of magnetic conveyer belt 4 is large, and therefore adsorbed ferromagnetic amount is many, ensure that efficiency of magnetic separation of the present utility model.Isolated separation chamber 2 and expansion chamber 3 ensure that being separated of the separation process of raw material and infall process, avoid influencing each other of two processes.
In order to realize better airborne dust effect in separation chamber, raw material is made to contact magnetic conveyer belt 4 fully, in an embodiment of the present utility model, separation chamber 2 sidewall and described dividing plate 5 are provided with multiple air blast 10, the wind that multiple air blast 10 goes out forms air channel, and magnetic conveyer belt 4 is positioned at air channel.The raw material fallen to bottom separation chamber 2 is kicked up by the air blast 10 on the bottom of separation chamber 2, sidewall and described dividing plate 5, makes it move in air channel, thus all raw materials can be made fully to contact magnetic conveyer belt 4.
In order to avoid causing raw material caking and the coated ferromagnetic of dust to cause magnetic separation obstacle due to the silt in raw material and moisture, in an embodiment of this practical information, the air port place of described air blast 10 is provided with heating net 11.Which ensure that the wind that air blast 10 blows out is hot blast, be conducive to the evaporation accelerating moisture in raw material, and quickly the dust being coated on ferromagnetic outside dispelled ferromagnetic is exposed, substantially increase raw material availability.
