Abstract

Dispositivo extractor (30) destinado a extraer una cuña (20) de cortocircuito insertada entre dos conductores (24 y 25) para apagar una celda (2) electrolítica. El dispositivo extractor (30) comprende un medio de cogida (31) de dicha cuña y, a la cara horizontal superior (240, 250) de cada conductor (24, 25), por lo menos un cilindro (324, 325) orientado verticalmente y que comprende un cuerpo (320) y una varilla (321), a) formando dicha varilla (o dicho cuerpo) parte integrante de por lo menos una cara de apoyo horizontal (335) orientada hacia abajo y dispuesta de manera que, cuando dicho dispositivo extractor está colocado arriba de dicha cuña para extraerla, la dicha cara horizontal superior (240, 250) del conductor (24, 25) se encuentra a la vertical de dicha cara de apoyo horizontal (335), b) estando dicho cuerpo (o dicha varilla) unida a dicho medio de cogida (31) de dicha cuña de manera que, cuando se acciona dicho cilindro (32) para efectuar la extracción de la cuña, dicho cilindro ejerce, sobre dichos conductores y sobre dicha cuña, esfuerzos opuestos que tienden a separarlos.
