The present invention relates to a device for on-line measuring anode current
distribution of an aluminum electrolytic cell. The device comprises the
following
structures: an insulating connector body which inside is provided with a
measuring
contact and which outside is fixed on a fastening means. The measuring contact
is a
metal conductor, one end of the measuring contact is threaded, and the
measuring contact
is fixed with the insulating connector body via the threaded end. Advantages
of the
present invention are as follows: the present invention is advantages in a
simple structure,
safe operations, a long service life, easy installation and removal, lower
manpower costs,
a reduced cell effect coefficient, and reduced energy consumption of the
aluminum
factory. Since the adjusting nut for fastening and adjusting looseness is
installed at the
opening of the concave-shaped steel strip, in a completely open state the
fastening means
is completely open on one side so that the means can be smoothly and quickly
installed
on the guide rod; a gap can be adjusted in the locked state so as to ensure
close contact
between the measuring contact and the anode guide rod.
L'invention concerne un dispositif de mesure de distribution de courant d'anode de cellule électrolytique d'aluminium en ligne comprenant un connecteur d'isolation. Un contact de mesure, qui est un conducteur métallique, est disposé sur le côté intérieur du connecteur d'isolation, le côté extérieur du connecteur d'isolation étant fixé sur un dispositif de fixation. Une extrémité du contact de mesure est pourvue d'un fil, et le contact de mesure est fixé au connecteur d'isolation via l'extrémité pourvue du fil. Du fait qu'un écrou de réglage, qui peut être fixé avec une tension réglable, est monté sur une ouverture de bande d'acier concave à l'état complètement ouvert, un côté du dispositif de fixation est complètement ouvert, ce qui assure le montage rapide et réussi du dispositif sur une tige de guidage ; tandis qu'à l'état verrouillé, un espace peut être réglé, ce qui assure un contact étroit entre le contact de mesure et une tige de guidage d'anode. Le dispositif est facilement montable et démontable, ce qui permet de réduire le coefficient d'effet de cellule et de mettre en uvre des économies d'énergie et une réduction de consommation pour le fabricant d'aluminium.
