Abstract
The utility model discloses a Chinese-character-feng-shaped stepped cathodic carbon block of an aluminum reduction cell. The lower part of single cathodic carbon block is of a rectangle, the upper part is of a step shape, the lower rectangle is larger than the upper step shape, and the lower end of the rectangle is provided with a notch for mounting a steel sample; and a plurality of cathodic carbon blocks are arranged at the bottom of an aluminum reduction cell, the middle part of the blocks form a groove which is form a shape like a Chinese character feng with the cathodic carbon blocks. Inthe utility model, the stepped part is added on the bottom surface of the cell of the original reduction cell, so that the conductive area of cathodes is increased, a magnetic field is more even, anddeposition can not appear; an evenly distributed structure in a shape like a Chinese character feng is formed on the bottom to be beneficial to cleaning and flow of aluminum liquid, so that the aluminum liquid is stable and has small fluctuation. The cathodic carbon block can greatly improve the electrolysis efficiency, reduce electricity and energy consumption and greenhouse gas emission and prolong the service life of the reduction cell.
Description
Technical field
The utility model relates to a kind of rich font staged cathode block of aluminium cell.
Background technology
Existing aluminium cell, its cathode block are the rectangular cathode carbon piece assembling of steel sample to be installed and to be built by laying bricks or stones by a plurality of bottoms to form.Used cathode block is a rectangular parallelepiped, electrolytic bath thorax basal surface is flat, be bundled into a rectangle pond with the carbon piece all around, separating matter by the aluminium power and water exists certain weight to keep pole span to keep the pressure reduction consumed power to reach the demand that liquid satisfies technology, and reach thermal equilibrium by heat radiation around the pot shell, add the influence that is subjected to the magnetic field that anodic gas that the anode basal surface overflows and the inside and outside electrical conductor electric current of electrolyzer produce, aluminium liquid instability in the electrolyzer, has very big fluctuation, this instability and fluctuation exert an influence to the power consumption and the current efficiency of electrolysis of aluminum, thereby there is the power consumption height in existing aluminium cell, pollute high, cell life is short, shortcomings such as electrolytic efficiency is low.
The utility model content
The purpose of this utility model is to overcome above shortcoming, and a kind of rich font staged cathode block of aluminium cell is provided.With realize to improve electrolytic efficiency, reduce power consumption, reduce exhaust gas emission, prolong electrolyzer work-ing life.
The technical solution of the utility model is: single cathode block bottom is rectangular, top is notch cuttype, the rectangle of its underpart is greater than the notch cuttype on top, be provided with the breach that the steel sample is installed in the orthogonal lower end, a plurality of cathode blocks are placed on aluminum electrolytic cell bottom, its middle part forms a groove, and groove and a plurality of cathode block constitute a rich font.
Described groove is similar V-shape or U font.
Described groove can be to have groove in the centre of the notch cuttype part of single cathode block, and a groove is formed in the middle on the bottom that a plurality of cathode block combinations are placed on aluminium cell.Also can be that a end in the notch cuttype of single cathode block part has a breach, be arranged in a row, form a groove in the middle more arranging the bottom that the cathode block combination is placed on aluminium cell by two cathode blocks.
Described notch cuttype part is made of 1-5 step, highly is 50-300mm.Bottom width is 100-390mm.
The utility model has increased the conductive area of negative electrode by increasing the notch cuttype part on the original electrolytic bath thorax basal surface basis, makes magnetic field more even, thereby can not produce precipitation; Form again in its bottom be evenly distributed rich font structure, help the cleaning of aluminium liquid and flow, make aluminium liquid stable, it is little to fluctuate; Can improve electrolytic efficiency, reduction power consumption and energy consumption, minimizing greenhouse gas emission greatly; And can prolong work-ing life of electrolyzer.
