The present invention grinds pounds giving that sieve disembarks and advocates to want top hopper from track obliquely, carry out timing feed through hoist engine, through grinding the compound of electrolyte, alumina powder and aluminium after pounding, through being arranged on the screen cloth at discharging opening place, sieve, sieve is lower is electrolyte and alumina powder, on sieve, be aluminium, the mixed compound of electrolyte and alumina powder carries out state through compound discharging opening, and aluminium packs through aluminium discharging opening.
More excellent scheme of the present invention is:
Described grinding pounded the sieve inside of disembarking and is provided with and grinds steel ball and wear-resisting screen and liner plate, and its bottom is provided with rotary screen extension set.
Grinding grinding of pounding that sieve disembarks, to pound principle be to adopt steel ball grinding and throwing to pound two aspects to form.During operation, at the bottom of part steel ball and aluminium slag cylinder, grind, another part steel ball and aluminium slag are risen to certain altitude by screen, again by gravity throw lower aluminium slag pound loose, crack, through above grinding in 20 minutes, pound, it is separated that the electrolyte that makes aluminium slag internal package and alumina powder are able to, and grinds compound separated after having pounded and automatically enter rotary screen extension set, and aluminium and electrolyte are discharged and packed from discharging opening separately respectively.
Described elevating hopper top and grinding is pounded charging aperture, the discharging opening place that sieve disembarks and is provided with exhaust column, and exhaust column is connected with the air inlet of pulsed jet cloth filter; Pound sieve and disembark when operation grinding, form negative pressure in cavity, the airborne dust while guaranteeing blanking can recycle in time, guarantees that the environment in workplace avoids the pollution of dust, reaches environmental protection standard.
Described pulsed jet cloth filter is the MC type pulse bag formula deduster of can trap >=200 order inserts.
Described exhaust column is hard steel pipe.
The present invention adopts to grind to pound principle, solve the aluminium oxide being wrapped up by aluminium in aluminium slag and be difficult to a separated difficult problem with electrolyte, the separation rate of aluminium slag reaches 100%, and aluminium oxide and electrolyte are back to use electrolytic cell again, aluminium directly keeps stove reuse through foundry, effectively reduces production cost; Utilize the effect of gathering dust of negative pressure system, reduce aluminium oxide and the harm of electrolyte dust to worker, collect >=200 object powders simultaneously, improve worker's operating environment, reduce dust to the pollution inside and outside factory building.
The feature such as that the present invention has is simple in structure, reasonable in design, be skillfully constructed, utilization is ground and is pounded principle, thoroughly solved a difficult problem of wrapping up electrolyte and alumina powder in aluminium slag, utilize deduster to solve to grind the problem of dust pollution kicked up in the process of pounding simultaneously, purify bad border of operation, reached the object of economize expense and reduce expend, safety and environmental protection, applied widely, practical, be easy to promote.
(4) accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further illustrated.
Fig. 1 is structural representation of the present invention.
In figure, 1 elevating hopper, 2 material loading tracks, 3 grind pound sieve disembark, 4 compound discharging openings, 5 pulsed jet cloth filters, 6 aluminium discharging openings.
(5) specific embodiment
Accompanying drawing is a kind of specific embodiment of the present invention.This embodiment comprise front end arrange grinding of elevating hopper 1 pound sieve disembark 3, described grinding pounded disembark 3 charging aperture of sieve and is provided with the material loading track 2 of inclination, material loading track 2 belows are provided with the elevating hopper 1 that hoist engine is installed, and grind to pound disembark 3 discharging opening place of sieve and be provided with compound discharging opening 4 and the aluminium discharging opening 6 of separating by screen cloth; Described grinding pounded sieve 3 inside of disembarking and is provided with and grinds steel ball and wear-resisting screen and liner plate, and its bottom is provided with rotary screen extension set; Described elevating hopper 1 top and grinding is pounded disembark 3 charging aperture, discharging opening place of sieve and is provided with exhaust column, and exhaust column is connected with the air inlet of pulsed jet cloth filter 5; Described pulsed jet cloth filter 5 is MC type pulse bag formula dedusters of can trap >=200 order inserts; Described exhaust column is hard steel pipe.
