Abstract
The utility model belongs to the technical field of aluminum electrolysis and specifically relates to an aluminum electrolysis cell cathode carbon block with cylindrical grooves on an upper surface. According to the aluminum electrolysis cell cathode carbon block, two rows of the 5-8 cylindrical grooves are arranged on the upper surface of the aluminum electrolysis cell cathode carbon block along the length direction of the upper surface, the diameters of the cylindrical grooves are 200-300mm, the depth of the cylindrical grooves is 50-100mm, and the two rows of the cylindrical grooves are ranked in a staggering mode. According to the aluminum electrolysis cell cathode carbon block with the cylindrical grooves on the upper surface, reprocessing of the upper surface of the cathode carbon block is avoided in a later period, time saving and labor saving are achieved, electrode materials are saved, and processing difficulties caused due to hardness of the cathode carbon block are avoided.
Description
Technical field
The utility model belongs to technical field of aluminum electrolysis, is specifically related to a kind of upper surface with the aluminium electrolytic cell cathode charcoal piece of cylinder groove.
Background technology
Industrial aluminium is produced with sodium aluminum fluoride-alumina molten salt electrolysis method, Aluminium Electrolysis need to consume a large amount of electric energy, therefore, economize on electricity is the technical problem underlying that Aluminium Electrolysis faces all the time, concerning Aluminium Electrolysis, the saving of its electric energy mainly is by the bath voltage that reduces electrolyzer and improves current efficiency and realize.Before 2008, the direct current consumption of Aluminium Electrolysis is more than the 13200kWh/t-Al always both at home and abroad, on March 2nd, 2007, Feng Naixiang was invented a kind of electrolysis of aluminum patented technology (ZL200710010523.4) of novel cathode structure electrolyzer, and after industrial cell is used, so that the direct current consumption of Aluminium Electrolysis is reduced to about 12000kWh/t-Al, Feng Naixiang has been invented again a kind of patented technology of the aluminium cell of inlaying stud bump (CN101864580A) of cathode carbon pieces upper surface afterwards, this technology has the stability that more can effectively improve electrolyzer inner cathode liquid aluminum than the former, thereby can make the current efficiency loss still less, power consumption is lower, the characteristics that this cathode carbon pieces upper surface is inlaid with the cathode structure of aluminium cell of stud bump be each cathode carbon pieces upper surface be inlaid with along the longitudinal direction 2 row or 2 row more than projection, the interlaced arrangement of adjacent two organ timbering types projection, stud bump is to be processed into the groove of round tube type in the position in accordance with regulations at the upper surface of cathode carbon pieces first at the installation method of cathode carbon pieces upper surface, this round tube type groove inwall has screw thread, screw thread is also arranged at the bottom of stud bump, the cartridge type projection relies on these screw threads to be installed in the upper surface of cathode carbon pieces, but in this way, when the cartridge type groove of processing above the cathode carbon pieces, both time-consuming, require great effort again, also sacrificial electrode material, the matrix of particularly working as the cathode carbon pieces of processing is to be that main material is when making by calcined anthracite, the hardness of its cathode carbon pieces is very large, and be difficult to processing, therefore this cathode carbon pieces is demanded urgently improving.
Summary of the invention
For above-mentioned technical problem, the utility model provides the aluminium electrolytic cell cathode charcoal piece of a kind of upper surface with cylinder groove, and its upper surface has the round tube type groove, need not post-production, can directly link to each other with column-shaped projection.
Upper surface of the present utility model is with the aluminium electrolytic cell cathode charcoal piece of cylinder groove, length direction at aluminium electrolytic cell cathode charcoal piece upper surface divides two to be arranged with the round tube type groove, the groove quantity of every row's round tube type is 5 ~ 8, diameter is 200 ~ 300mm, the degree of depth is 50 ~ 100mm, and the interlaced arrangement of two row's round tube type grooves is arranged.
Characteristics of the present utility model and beneficial effect are:
The utility model upper surface is with the aluminium electrolytic cell cathode charcoal piece of cylinder groove, removed from the later stage again the cathode blocks upper surface reprocess, time saving and energy saving, save electrode materials, avoided the processing difficulties that produces because of cathode carbon pieces hardness problem.
