The present invention grinds to pound and sieves the main top hopper of feed of disembarking and carry out timing feed through hoist engine from track obliquely, the screen cloth of compound through being arranged on discharge outlet of the electrolyte after grinding and pounding, alumina powder and aluminium sieves, sieve is lower is electrolyte and alumina powder, sieve is aluminium, electrolyte and alumina powder compound pack through compound discharging opening, and aluminium packs through aluminium discharging opening.
More excellent scheme of the present invention is:
Described grinding is pounded sieve inside of disembarking and is provided with grinding steel ball and wear-resisting screen and liner plate, and is provided with rotation sieve on the right side of it.
Grinding grinding of pounding that sieve disembarks, to pound principle be adopt steel ball grinding and throwing to pound two aspects compositions.During operation, grind at the bottom of part steel ball and aluminium slag cylinder, another part steel ball and aluminium slag are risen to certain altitude by screen, again by gravity throw lower aluminium slag pound loose, crack, pound through more than 20 minutes grind, the electrolyte of aluminium slag internal package is separated with alumina powder, grinds the compound be separated after having pounded and automatically enter rotation sieve, aluminium and electrolyte are discharged from respective discharging opening respectively and are packed.
Described elevating hopper top and grinding is pounded and is sieved charging aperture, the discharge outlet of disembarking and be provided with exhaust column, and exhaust column is connected with the air inlet of pulsed jet cloth filter; Grind pound sieve disembark run time, form negative pressure in cavity, airborne dust when ensureing blanking can recycle in time, ensures that environment in workplace is from the pollution of dust, reaches environmental protection standard.
Described pulsed jet cloth filter to trap the >=MC type pulse bag formula deduster of 200 order inserts.
Described exhaust column is hard steel pipe.
The present invention mainly adopts to grind pounds principle, solve the difficult problem that the aluminium oxide that wrapped up by aluminium in aluminium slag and electrolyte are difficult to be separated, 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, reduction aluminium oxide and electrolyte dust, to the harm of worker, are collected >=200 object powders simultaneously, are improved the operating environment of worker, reduce dust to the pollution inside and outside factory building.
The present invention has that structure is simple, reasonable in design, the feature such as be skillfully constructed, utilization is ground and is pounded principle, thoroughly solve a difficult problem for parcel electrolyte and alumina powder in aluminium slag, utilize deduster to solve the problem of grinding in the process of pounding dust pollution of kicking up simultaneously, purify operation bad border, reach 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 and pound sieve and disembark, 4 compound discharging openings, 5 pulsed jet cloth filters, 6 aluminium discharging openings.
(5) detailed description of the invention
Accompanying drawing is a kind of specific embodiment of the present invention.This embodiment comprises front end and arranges grinding of elevating hopper 1 and pound sieve and disembark 3, described grind pound sieve disembark 3 charging aperture be provided with the material loading track 2 of inclination, be provided with below material loading track 2 and the elevating hopper 1 of hoist engine be installed, grind pound sieve disembark 3 discharge outlet be provided with the compound discharging opening 4 and aluminium discharging opening 6 that screen cloth separates; Described grinding is pounded sieve 3 inside of disembarking and is provided with grinding steel ball and wear-resisting screen and liner plate, and is provided with rotation sieve on the right side of it; Described elevating hopper 1 top and grinding pound sieve disembark 3 charging aperture, discharge outlet be provided with exhaust column, exhaust column is connected with the air inlet of pulsed jet cloth filter 5; Described pulsed jet cloth filter 5 is MC type pulsed jet cloth filters of trapping >=200 order inserts; Described exhaust column is hard steel pipe.
