Description
Technical field
The present invention relates to a kind of alumina transferring method, more particularly to a kind of electrolytic aluminium factory alumina transferring method.
Background technology
With the production-scale continuous increase of modern Large aluminum electrolytic plant, needed using substantial amounts of alumina raw material aborning.At home in Aluminum Electrolysis Production, alumina raw material is in the majority with bagged aluminum oxide, generally bagged aluminum oxide is transported in electrolytic aluminium factory aluminium oxide warehouse by automobile or train, bagged aluminum oxide is delivered to the fresh aluminum oxide bunker in the middle of two cell rooms by induction system Jing after unpacking, fresh aluminum oxide becomes fluorinated alumina into after fluoride in Smoke Gas Purity by Electrolysis system absorption flue gas, delivers to alumina reservoir electrolysis production and application on electrolytic bath by aluminium oxide feeding system.The position near factory road or railway is typically built in aluminium oxide warehouse in, and usual fresh aluminum oxide bunker needs to build in the middle of two cell rooms of homologous series because of cleaning system configuration.
Mainly there are at present concentrated phase conveying system, chute conveying or Belt Conveying technology etc. from aluminium oxide warehouse to the alumina transferring mode fresh aluminum oxide bunker, the factor such as actual fed way choice and system conveying capacity, plant area's landform is relevant.Shown by operative practice, Technology of Aluminum Oxide Dense-phase Transport has the shortcomings of conveying capacity is little, energy consumption is high, aluminium oxide degree of crushing is big, and this kind of mode of movement can not meet the requirement of modern Large Electrolytic Aluminium production；Chute mode of movement fed distance is short, and transporting chute is installed to be needed with angled, is limited by plant area's landform requirement；Belt Conveying technology has automatization and mechanization degree higher, and conveying capacity is big, production run low cost and other advantages, but its equipment and infrastructure construction high expensive.
The content of the invention
A kind of electrolytic aluminium factory alumina transferring method is provided in order to solve the above-mentioned technical problem present invention, it is therefore an objective to improve alumina transferring ability, reduce aluminium oxide degree of crushing.
It is to invent a kind of electrolytic aluminium factory alumina transferring method up to above-mentioned purpose, aluminium oxide warehouse and fresh aluminum oxide bunker are located between two potrooms, the one end of interface channel in the middle of two potrooms through aluminium oxide warehouse, the other end in aluminium oxide warehouse is provided with aluminium oxide unpacking device, the oxidized aluminum unpacking device of bagged aluminum oxide enters the first chute, then by the material-falling hopper of alumina transferring to bucket elevator, fresh aluminum oxide storing bin top is lifted with bucket elevator and entered in fresh aluminum oxide bunker by the second chute.
Overhead crane with hook and centrifugal fan and chute air feed system are provided with aluminium oxide warehouse.
Aluminium oxide unpacking device discharging opening is provided with hand operated gate valve and electric gate valve.
Dust arrester installation is externally provided with aluminium oxide warehouse.
It is arranged in parallel between two potrooms and aluminium oxide warehouse.
Aluminium oxide unpacking device is two, and bucket elevator is two.
Bagged aluminum oxide is transported to aluminium oxide warehouse by automobile, by overhead crane with hook handling bagged aluminum oxide.
Installation height level-sensing device in fresh aluminum oxide bunker, for indication bin internal oxidition aluminum material position situation, level-sensing device configured information and control system chain control；When level-sensing device indicates low material position, start alumina transferring, when level-sensing device indicates high charge level, stop alumina transferring.
Advantages of the present invention effect：The present invention adopts Automobile Transportation bagged aluminum oxide.By practice have shown that, the conveying of factory internal oxidition aluminum material is carried out using the present invention, rationally can utilize plant area vacant lot, reduced plant area and take up an area, reduction ton aluminum floor space；Aluminium oxide is static conveying in whole course of conveying, significantly reduces the abrasion during alumina transferring, is conducive to the demand of aluminum electrolysis；Alumina powder Jing bucket elevators after unpacking in aluminium oxide warehouse are delivered in aluminum oxide storage bunker, are reduced material conveying process, are reduced alumina material conveying energy consumption；Alumina material conveying flow process is short, reduces loss of material.The present invention is practical, and automatization and mechanization degree are high, and conveying capacity is big, can reduce the construction cost and production cost of electrolytic aluminium, can bring certain economic benefit for enterprise.
