Title
(PT) montagem de parafuso de extrusão de núcleo oco de alta transferência térmica
Abstract
(PT)
trata-se de parafusos de extrusão de núcleo oco de alta transferência térmica (50, 52, 124, 126, 190) que incluem eixos de núcleo oco alongados (54, 128, 130, 192) equipados com rosca helicoidal (56, 132, 134, 194) ao longo dos comprimentos da mesma. a rosca (132, 134, 194) também pode ser de construção oca que se comunica com os eixos de núcleo oco (54, 128, 130, 192). a estrutura (88, 90) é fornecida para entrega de meios de troca de calor (por exemplo, vapor) nos eixos de núcleo oco (54, 128, 130, 192) e a rosca oca (132, 134, 194). a rosca (56, 132, 134, 194) também inclui uma seção de passo reversa dianteira (64, 162, 216). os parafusos de extrusão (50, 52, 124, 126, 190) são projetados para serem usados como pares complementares como parte de dispositivos de processamento de parafusos gêmeos (20), e são projetados para conferir altos níveis de energia térmica em materiais que são processados nos dispositivos (20), sem adicionar umidade adicional.
