A flow guiding channel (3) is arranged on the negative electrode (2), a plurality of partition boards (4) are arranged between the positive electrodes (1), and the partition boards (4) are embedded in or placed on the upper surface of the negative electrode (2) of the aluminum electrolytic cell so as to form the multi-chamber aluminum electrolytic cell. The partition boards (4) adopt embedding type a flat board structure or a flat-placing type halfpace structure. The heights of the partition boards (4) are relatively higher than that of an aluminum liquid layer, and the spaces between the partition boards (4) are either identical or different. The partition-board multi-chamber aluminum electrolytic cell adopts unique partition board technology and is capable of effectively reducing horizontal current, slowing down and reducing radial flowing speed of the aluminum liquid layer, reducing fluctuation of aluminum liquid interface and secondary reaction of the aluminum liquid, improving stability of the electrolytic cell, improving current efficiency of the aluminum electrolytic cell and achieving energy saving and consumption reduction.
Description
Technical field
The utility model relates to a kind of dividing plate multicell aluminium cell, belongs to the aluminium cell technical field.
Background technology
During existing aluminium cell electrolysis production, the aluminium liquid of separating out is accumulated in charcoal piece negative electrode top, forms the aluminium liquid layer of certain altitude, and as the part of negative electrode.The influence that receives EM field owing to the aluminium liquid layer of certain altitude on the charcoal piece negative electrode moves overruns, and causes aluminium liquid secondary reaction probability to increase, and greatly reduces the current efficiency of aluminium cell.Along with the continuous development of aluminum electrolyzation technology, improve and industry policy, energy-conservation, consumption reduction on requirement, electrolyzer is gradually to large scale development, according to electrolysis of aluminum theory and production practice both domestic and external; The aluminium cell grooved is big more; Its phenomenon that bias current takes place is serious more, and aluminium liquid layer radially flow velocity is big more, makes the stability of electrolyzer poor more; Directly have influence on the ordinary production operation and management of aluminium cell; Cause the interior aluminium liquid interfacial layer fluctuation of groove excessive, increase secondary reaction reaction probability, reduce current efficiency.
Therefore, stop and slow down radially flow velocity of aluminium liquid layer, reduce trough inner water ordinary telegram stream, can effectively improve the stability of aluminium cell, reduce the fluctuation at aluminium liquid interface, improve current efficiency, realize energy-saving and cost-reducing.
Summary of the invention
The utility model technical problem to be solved is: a kind of dividing plate multicell aluminium cell is provided; This electrolyzer can effectively stop and slows down radially flow velocity of aluminium liquid layer, reduces trough inner water ordinary telegram stream, increases the stability at aluminium liquid interface; Reduce aluminium liquid secondary reaction; Cause in the groove fluctuation of aluminium liquid interfacial layer excessive with what overcome that prior art exists, increase secondary reaction reaction probability, reduce deficiencies such as current efficiency.
The technical scheme that the utility model adopted is: a kind of dividing plate multicell aluminium cell; Its anode, negative electrode are processed with curb on the negative electrode, several dividing plates are set between anode; Dividing plate is inlayed or is positioned over the aluminium electrolytic cell cathode upper surface, forms the multicell aluminium cell.
Be processed with curb on the electric tank cathode charcoal piece, the aluminium liquid that electrolytic reaction produces can flow into the Aluminum storage pond through curb.
Dividing plate adopts inserted slab construction or flatwise halfpace structure.
Said dividing plate height is a little more than the aluminium liquid layer.
The spacing of dividing plate adopts equidistance or equidistance not.
The beneficial effect of the utility model: this aluminium cell adopts to be inlayed or the halfpace diaphragm structure; Can effectively stop and slow down radially flow velocity of aluminium liquid layer, reduce trough inner water ordinary telegram stream, reduce the fluctuation of aluminium liquid interface; Improve the stability of electrolyzer; Reduce the secondary reaction of aluminium liquid, effectively improve the current efficiency of aluminium cell, realize energy-saving and cost-reducing.
