Abstract

Un dispositivo (1) per introdurre un fluido ad elevata temperatura in un corpo rotante comprende un tubo (2), al cui interno è previsto che passi il detto fluido e che è destinato al collegamento solidale con il detto corpo rotante. Il tubo (2) è accoppiato girevolmente ad un supporto (6) mediante cuscinetti (7). Allo scopo di ridurre lo stress termico dei cuscinetti (7), un fluido di raffreddamento viene alimentato ad un condotto (11), anulare, che è interposto, con solidarietà alla rotazione con il tubo (2), fra i cuscinetti (7) e il tubo (2) stesso e che presenta un ingresso (12) e un'uscita (13) per il fluido di raffreddamento. In particolare, il dispositivo (1) serve nell'industria cartaria per introdurre un fluido diatermico in un cilindro di essiccazione o di calandratura della carta.(Fig. 1).
