Abstract

Dispositivo de recubrimiento por pulverización, que contiene un canal de polvo (8); un porta-electrodo (24), que está colocado en la sección extrema, posterior en el trayecto, del canal de polvo y presenta una pieza tubular (26) en una pieza de material eléctricamente aislante, que constituye una sección del canal de polvo, teniendo su sección de pieza tubular trasera (28), anterior en el trayecto, un diámetro exterior menor que una sección de pieza tubular (30) subsiguiente dirigida hacia adelante; un dispositivo eléctrico de contacto (34, 38) para poner en contacto con un conductor de alta tensión (20) con una línea eléctrica de conexión (40), que se extiende por el porta-electrodo (24) hasta al menos un electrodo de alta tensión (22) soportado por aquél, estando dispuesto el dispositivo de contacto (34, 38) en un saliente (32) dirigido hacia atrás entre las dos secciones de pieza tubular (28, 30); caracterizándose el dispositivo porque la distancia axial entre el dispositivo eléctrico decontacto (34, 38) y el extremo trasero de la sección trasera de pieza tubular (28) asciende al menos a 1, 5 cm y porque en el saliente (32) dirigido hacia atrás está formada una ranura (44) que rodea el canal de polvo (8), anularmente, distanciada radialmente, que, por una parte, está unida con un canal de aire a presión (46) y, por otra parte, está unida con un canal de aire (48), que se extiende por el porta-electrodo (24), mediante el cual puede ser suministrado aire a presión al por lo menos un electrodo (22).
