Description
One, technical field
The invention belongs to metallurgy of aluminium technical field, be specifically related to a kind of efficient device for extracting high pure aluminum.
Two, background technology
At present; Non-ferrous metal industry both domestic and external, aspect the smelting purification of ultra-high purity metal aluminium, what mainly adopt is directional solidification method and two kinds of technology of zone melting method; Be induction areas and metallic aluminium melting pot; Relatively slowly first movably with the metallic aluminium heat fused, and then slow refrigerative purifying technology, and the type of furnace has horizontal and vertical two kinds.For example patent name is that " device for extracting high pure aluminum " (patent No. is: the extraction element that 200610134389.4) just discloses a kind of vertical type of furnace.This device comprises vertical truncated cone-shaped pot body, support and the lifting mechanism in vertical blade round shape electromagnetic induction boiler clothing, the boiler clothing; The top of the blade round shape boiler clothing outwards blade end of turnover is the terminals of three-phase electricity, and the upper end of vertical truncated cone-shaped pot body has the feed inlet and outlet of flange seal; Lifting mechanism is installed in the top of flue.This device is owing to adopted the columnar electromagnetic induction boiler clothing of vertical blade, and the blade end on its top inserts three-phase alternating current, makes the electric current of vertical electromagnetic induction boiler clothing mobile along the axis direction of boiler clothing, makes boiler clothing become the stator of asynchronous motor.After the intravital refined aluminium of truncated cone-shaped pot is heated by boiler clothing in the boiler clothing, be fused into liquid state and be filled in pot body, the intravital aluminium liquid of pot just becomes rotor like this; When boiler clothing feeds three-phase alternating current, just form rotatingfield, make and the intravital aluminium liquid rotor of pot rotate all the time around the pot body axis; Make the high speed circumferential motion; Aluminium liquid is stirred, under centrifugal action, slowly promote the pot body this moment; Because the liquidus temperature Gradient Effect of pure metal and its impurity at first freezes solidly on the truncated cone-shaped internal wall pot body on top the liquidus temperature metallic aluminium high than impurity.And liquidus temperature is lower than the impurity of metallic aluminium, and it still keeps liquid under criticality, and is being rotated and pushes a pot body lower end enrichment to, thereby isolates the impurity in the refined aluminium effectively, has obtained rafifinal.Owing to reasonably utilize the complex art effect of aspects such as gravity, electric field, electric heating, hydromeehanics and metallography; Make when in fusion process, promoting the pot body; The freezing interface does not have tomography, and disposable melting was purified more horizontal purifying plant shortening of time more than 3 hours; The purity of disposable melting rafifinal reaches more than 99.9995%, is equivalent to horizontal purifying plant and draws the purity of moving melting 5-15 times; The refined aluminium utilization ratio of raw materials improves 5%, obtains good refining effect.But in use there is following deficiency in this device: 1, owing to adopt single pot of running body, all to wait pot body to accomplish a work period at every turn after, just can descend wheel operation, working efficiency is lower; 2, each pot body upwards promote 10 surplus hour process in because the electromagnetic induction boiler clothing must be supplied power all the time.Like this, slowly promote in the purification process, have 40% electric energy to be slatterned in vain approximately at the pot body; 3, power-supply unit wastes electric energy more and so on, so increased bigger running cost.
Three, summary of the invention
The purpose of this invention is to provide a kind of high efficiency, waste the little efficient device for extracting high pure aluminum of electric energy.
For realizing above-mentioned purpose, the technical scheme that the present invention adopts is: this device comprises furnace shell, electromagnetism resistance boiler clothing in the furnace shell that is supported on the support and the cylindrical pot body that is centered on by electromagnetism resistance boiler clothing; Electromagnetism resistance boiler clothing is that vertical blade is columnar structured, and its top outwards blade end of turnover is power connection end; Be characterized in: described cylindrical pot body is made up of folded top purification compound pot and the bottom purification ingot casting compound pot that drops on together; The feed inlet and outlet of purification compound pot is sealed by blind flange, and its upper outside is provided with supporting cup; The lower end of purification ingot casting compound pot is supported on holder and rises in the mechanism.
Adopt said structure; During use, electromagnetism resistance boiler clothing heats the purification compound pot earlier, and is holding in the palm lifting purification under the drive that rises mechanism; Purification ingot casting compound pot is sent into preheating in the electromagnetism resistance boiler clothing gradually in lifting process; After the purification compound pot on top was all pulled out electromagnetism resistance boiler clothing, the purification ingot casting compound pot that has all got into the bottom in the burner hearth began further heating, at this moment; Take out the rafifinal product after purifying in the purification compound pot, be reset to purification ingot casting compound pot top after raw material to be purified is inserted.When the purification ingot casting is compounded in drive that holder rises mechanism when descending down purification; Purification compound pot after resetting is got back to preheating in the electromagnetism resistance boiler clothing gradually, and after purification ingot casting compound pot all lifted out electromagnetism resistance boiler clothing, the purification compound pot was under the support of supporting cup; In electromagnetism resistance boiler clothing, be further heated; At this moment, take out the rafifinal product after purifying in the purification ingot casting compound pot, be reset to purification compound pot bottom after raw material to be purified is inserted.Like this, two upper and lower alternate repetition heating of pot body are purified, and working efficiency has obtained great lifting.The pot body promote or the decline process in, all the time wherein another pot body is carried out preheating, avoided waste of electric energy, waste electric energy and obtained great reduction, reduced running cost.With 50kg.30kw/ platform furnace gauge, only this time can save smelting time more than 2 hours for every pot, economize on electricity 20kwh; Every table apparatus can increase production 65 pots times every year more, can 2.6 tons of rafifinals of fecund; 1 ton of every purification time product 500kwh that can economize on electricity.Simultaneously, because purification ingot casting compound pot is to descend to purifying, rafifinal is to begin crystallization from the bottom; Be solid in the rafifinal crystallisation process; Need not only need that the rafifinal in the purification compound pot is carried out the ingot casting processing and get final product again through the ingot furnace secondary cast, the ingot casting workload reduces half the; Improve production efficiency greatly, reduced running cost.
