Embodiment one: 1.5 meters of the internal diameter of cabinet cylinder 1 of the present invention, interior 0.78 meter of the wealthy height of cabinet 1, driving motor 6 Power 4.5kW, 50 cubic metres per minute of the air quantity of cfentrifugal blower 7,50 turns per minute of the revolving speed of big belt wheel 25, outlet row The internal diameter of expects pipe 5 is 100 millimeters, and when use first connects external bagroom and outlet drainage conduit 5, by external receipts Batch can or bag are connected with lower discharge component 4, by the feeding part of external charging facility and the material feeding component being fixed on cabinet Part 3 connects, and turns off lower material feeding cone valve 26, discharge cone valve 28, opens air inlet control valve, then starts driving motor 6, this When, driving motor 6 drives cfentrifugal blower 7 to bustle pipe air feed and through entering the wind the air blast into cabinet 1 of connecting tube 17, small belt pulley 13 operate and big belt pulley 25 are driven to rotate, and the drive of big belt pulley 25 is pulverized component 2 and rotated in cabinet 1, slowly open material feeding Cone valve 26, by glue, accompany lime-ash and restore carbon residue, largest grain size be not more than material feeding valve opening diameter 1/4 500kg sponge iron Granular material is added in cabinet 1, the material of addition muller 23 roll under the stirring of spade scraper plate 22, material or deformation Or be grinded up, the metallic iron in granular material is under the rolling of muller 23, because ductility well can be elongated or can broaden or can become It is flat and be not easy to become broken and become smaller, on the contrary, glue, after the lime-ash, the reduction carbon residue that are clipped between metallic iron are rolled, because with iron stress Deflection afterwards it is different and occur peel off or break-off, furthermore, because lime-ash and restore carbon residue particle ductility it is bad and It is crisp rolled after be easy become it is broken attenuate, at this point, these attenuate the lime-ash to become smaller, reduction carbon residue, on the one hand because of the small another party of granularity Face is suspended in the air-flow of cabinet 1 under the blowing from air inlet 17 air-flow of connecting tube because specific gravity is small, and under the entrainment of air-flow Together with wind from outlet drainage conduit 5 be discharged, into external bagroom in and be collected in cloth bag, gas from cloth bag receive The discharge of dirt device, in this process, inorganic non-metallic material is fewer and fewer in remaining material in cabinet 1, and is added to cabinet 1 Metallic iron in material is trapped in the percentage in cabinet 1 made metallic iron in surplus material and increases, by after twenty minutes (depending on quilt The height of separation of material tenor and crossing whether there is or not metal pulverizes, and the time can appropriate adjustment), air inlet control valve is at this moment closed, is beaten The discharge cone valve 28 of lower discharge component 4 is opened, the material in cabinet 1 is under the scraping of spade scraper plate 22, by lower discharge out of cabinet 1 Mouth discharge, into external rewinding container, the total recovery rate of choosing point of available metal iron charge, metallic iron is greater than 98%, in this way It is achieved that the mesh for separating the inorganic non-metallics ingredient such as metal ferrous components and lime-ash, reduction carbon residue in sponge iron on one device 's.

Embodiment two: in the use of the present invention, formerly connecting external box bagroom with outlet drainage conduit 5 It is good, external rewinding tank or bag are connected with lower discharge component 4, by external charging facility and be fixed on cabinet 1 by After the receiving opening of material component 3 connects, then by the gas discharge outlet of box bagroom through circulation air piping and this equipment The air inlet of cfentrifugal blower 7 be connected (in this way, the wind of centrifugation air blast can through air intake assembly, through cabinet 1, through outlet drainage conduit 5, the air inlet that cfentrifugal blower 7 is entered back into through box 1 bagroom, through recycling air piping forms sealing and circulating, can Avoid gas leakage), lower material feeding cone valve 26, discharge cone valve 28 are closed, air inlet control valve is opened, then starts driving motor 6, this When, driving motor 6 drives cfentrifugal blower 7 to bustle pipe air feed and through entering the wind the air blast into cabinet 1 of connecting tube 17, small belt pulley 13 operate and big belt pulley 25 are driven to rotate, and the drive of big belt pulley 25 is pulverized component 2 and rotated in cabinet 1, slowly open material feeding Cone valve 26, by glue, accompany lime-ash and restore carbon residue, largest grain size be not more than material feeding valve opening diameter 1/4 500kg electrolytic aluminium Slag is slowly added in cabinet 1, and adjusting air inlet control valve is adapted intake and the air quantity of sorting aluminium slag, and electrolytic aluminum residue is being ground Rolling for wheel 23 is deformed or is grinded up under the stirring of spade scraper plate 22, and elasticity is good, ductility is not easy well for metallic aluminium in aluminium slag It pulverizes, only the granule-morphology of aluminium changes such as: elongated or broaden or become flat, the inorganic non-gold for pressing from both sides, being sticked in electrolytic aluminum residue It is different with the deflection of metallic aluminium after category ingredient stress, and then peeling or break-off occurs, furthermore, because of nothing in aluminium slag ingredient Machine Non-metallic components ductility is bad and crisp, is grinded up in crushing process, and particle size attenuates inorganic non-in small aluminium slag Metal component is simultaneously from air inlet air-flow and injects in cabinet 1 downwards through wind-distributing pipe 18 is tangential because granularity is small and specific gravity is small, Eddy flow is formed in cabinet 1, in the aluminium slag for driving the small specific gravity of particle small inorganic non-metallic ingredient (i.e. ash content) suspend in the gas flow, from Outlet discharge gate 5 is discharged, into bagroom after the filtration through the cloth bag that gathers dust, inorganic non-metallic ingredient is (i.e. in aluminium slag Ash content) it stays in bag, gas forms closed cycle from the air inlet that bagroom escapes and enter cfentrifugal blower 7, this When cabinet 1 in remaining material in inorganic non-metallic it is fewer and fewer, and the metallic iron being added in 1 material of cabinet stays in cabinet In, after 15 minutes (height and crossing whether there is or not metal depending on separated object material tenor pulverizes, and the time can be with appropriate adjustment), Percentage of the metallic aluminium in surplus material is higher and higher, at this moment closes air inlet control valve, opens the discharge cone of lower discharge component 4 Valve 28, the material in cabinet 1 are discharged out of cabinet 1 by lower discharge gate, under the scraping of spade scraper plate 22 into external rewinding In tank or bag, available metallic aluminium material has reached in electrolytic aluminum residue metal aluminium component on one device and electrolytic aluminum residue The separation purpose of ash content ingredient.

The present invention can be achieved to pulverize to be integrated in one with choosing point, there is that device category is few, process is few, occupied ground is few, process damage The low advantage of consumption rate.
