Abstract
The utility model discloses a mosaic cathode block which comprises a cathode block (1) and a cathode carbon rod (2) installed on the cathode block, wherein the cathode block (1) is provided with a mosaic carbon block (3). By inlaying the carbon block on the cathode block, the mosaic cathode block can lead a smooth cathode surface to be provided with raised strips, the raised strips can set up a barrier for a liquid aluminum high-flow rate area to damage the liquid aluminum inner flow field distribution generated by the original electromagnetic force so as to lead the distribution to be fragmented and the liquid aluminum not to be capable of generating bigger promontory and fluctuation, thus obtaining better stability, and when producing electrobath with better stability, the polar distance can be lower and the energy consumption can be less, thus achieving the effects of energy conservation and consumption reduction.
Description
Technical field
The utility model relates to a kind of inserted cathode carbon pieces, belongs to the aluminium cell technical field.
Background technology
In aluminium cell is produced, cloudy in the groove, aluminum oxide fused salt electrolysis process meeting precipitating metal aluminium liquid or aluminium drip between the anode, metal aluminium liquid or aluminium drip and generally all can compile or flow through the cathode carbon pieces surface of building by laying bricks or stones in groove thorax bottom, at present, much more smooth the cathode carbon pieces surface that constitutes aluminium electrolytic cell cathode is, like this along with the progressively increase of modern aluminum tank current capacity, the metal aluminium liquid of separating out in the electrolyzer will be more, pile up at cathode surface, be subjected to electromagnetic field effects and interference because of the flow characteristics of metal aluminium liquid simultaneously on the cathode carbon pieces surface, be subjected to electromagnetic field effects and interferential degree will further aggravate to form eddy flow and pile up aluminium liquid, thereby badly influence the stability of electrolysis production, hinder the raising of electrolytic cell currents efficient and the reduction of energy consumption.
The utility model content
The technical problems to be solved in the utility model is, a kind of inserted cathode carbon pieces is provided, and it can change the flow characteristics of metal aluminium liquid on the cathode carbon pieces surface by inlaying the charcoal piece, to reach effect energy-conservation, consumption reduction, can overcome the deficiencies in the prior art.
The technical solution of the utility model; It comprises cathode block and the negative carbon that is installed on the cathode block, is provided with on cathode block and inlays the charcoal piece.
On cathode block, be provided with the negative electrode groove, inlay the charcoal piece and be embedded in the negative electrode groove.
Be marked with stopping composition inlaying between charcoal piece and the negative electrode groove.
That inlays charcoal piece and negative electrode groove is shaped as rectangle, trapezoidal or trilateral.
Inlaying the charcoal piece is smokeless coal pieces, semi-graphite charcoal piece or semi-graphited or graphitized charcoal piece.
Stopping composition can be carbon paste or charcoal clay etc., and it mainly acts on is to bond and fixedly inlay the charcoal piece to be difficult for coming off with cathode carbon pieces.
Compared with the prior art, the utility model is by inlaying the charcoal piece on cathode block, so just can make existing smooth cathode surface have the projection band, the projection band can be provided with certain obstacle to aluminium liquid high-flow area, destroy the distribution of velocity field in the aluminium liquid that original electromagnetic force produces, make it become incoherent, make aluminium liquid can not produce bigger protuberance and fluctuation, thereby obtain stability preferably, and stability electrolyzer preferably, pole span can be lower during production, energy consumption is also lower, reaches effect energy-conservation, consumption reduction.Inlaying the charcoal piece is by establish the negative electrode groove on cathode block, be connected in the negative electrode groove will inlaying the charcoal piece by stopping composition, the method that the charcoal piece is inlayed in this connection can guarantee the stability of charcoal piece, and relative save energy, economical with materials is inlayed the arbitrary position that the charcoal piece also can be embedded in cathode carbon pieces.That inlays the charcoal piece is shaped as rectangle, trapezoidal or trilateral, can improve the range of application of inlaying the charcoal piece like this, make and inlay the aluminium cell that the charcoal piece is suitable for any kind, the material that the charcoal piece is inlayed in making is smokeless coal pieces, semi-graphite charcoal piece or semi-graphited or graphitized charcoal piece, above-mentioned making material is the material of making existing cathode carbon pieces, do not need other exotic materials, so the utility model can not increase too many fund in addition.While the utility model also has simple in structure, and the low and easy-to-install characteristics of cost of manufacture can be effective aluminium liquid flow characteristics of improving cathode surface and create good conditions, and have good economic benefits.
