Abstract

DISPOSITIVO PARA EXTRUSÃO DE MATERIAL SINTÉTICO TERMOPLÁSTICO. A presente invenção refere-se a um dispositivo para extrusão de material sintético termoplástico, com um parafuso sem-fim extrusor (2), montado em um alojamento (1) que abrange um segmento de plastificação (P) do lado da admissão, um segmento de desgaseificação (E) precedendo o segmento de descarga (A), e entre o segmento de plastificação (P) e o segmento de desgaseificação (E), um bloqueio de fluxo de passagem (S) com um segmento do parafuso sem-fim com rosca de reciclagem (3) em direção contrária e com ao menos um canal de fluxo (5) que ultrapassa em ponte o bloqueio de fluxo de passagem (S), contendo um filtro de fusão (4). Para diminuir o potencial de acionamento do parafuso sem-fim extrusor (2), é proposto que ao segmento do parafuso sem-fim, formado do bloqueio de fluxo de passagem (S), seja alocada uma luva (7) que envolve o parafuso sem-fim (6), montada à prova de giro dentro do alojamento (1), sendo que o parafuso sem-fim (6), no segmento do parafuso sem-fim do bloqueio de fluxo de passagem (S), tenha um diâmetro de parafuso sem-fim menor em relação ao segmento de plastificação (P) e ao segmento de desgaseificação (E).
