Abstract

resumo patente de invenção: "fundidor de alumínio, compreendendo cubas com saída catódica pelo fundo da caixa e dos meios de estabilização das cubas". a presente invenção refere-se a fundidor de alumínio, compreendendo: (i) uma série de cubas (2) de eletrólise, compreendendo um anodo (9), um catodo e uma caixa munida de uma parede lateral (7a) e de um fundo, cada catodo compreendendo pelo menos uma saída catódica (12); (ii) um circuito elétrico principal percorrido por uma corrente de eletrólise, compreendendo um condutor elétrico (14) ligado a cada saída catódica (12) de uma cuba n, e ao anodo (9) de uma cuba n+1, (iii) um meio para estabilizar as cubas (2) de eletrólise dentre um circuito elétrico secundário (5, 6) ou a utilização de um catodo com superfície intervalada. uma das saídas catódicas (12) da cuba n atravessa o fundo da caixa; cada condutor elétrico (14) se estende a partir de cada saída catódica (12) da cuba n em direção da cuba n+1 e é percorrido, quando do funcionamento das cubas (2) de eletrólise n, n+1 pela corrente de eletrólise em um sentido a montante - a jusante unicamente.Patent Specification: "Aluminum smelter, comprising cathode-outlet vats at the bottom of the housing and vat stabilizing means". The present invention relates to an aluminum smelter comprising: (i) a series of electrolysis vats (2) comprising an anode (9), a cathode and a housing provided with a side wall (7a) and a bottom each cathode comprising at least one cathode outlet (12); (ii) a main electrical circuit traversed by an electrolysis current, comprising an electrical conductor (14) connected to each cathode outlet (12) of an n-bowl, and to the anode (9) of an n + 1-bowl, (iii) a means for stabilizing the electrolysis vats (2) within a secondary electrical circuit (5, 6) or the use of an interval surface cathode. one of the cathode exits (12) of the bowl does not cross the bottom of the box; each electrical conductor (14) extends from each cathode outlet (12) of vat n towards vat n + 1 and is traversed when electrolysis vats (2) n, n + 1 are operated by electrolysis current in an upstream sense - downstream only.
