Abstract

"BOCAL DE DESCARGA ROTATIVO AJUSTáVEL". Um bocal de descarga (38) inclui um duto de descarga (36) com uma saída e uma fileira de aberturas radiais (48) a montante dele. Um quadro radial (58) circunda o duto a montante das aberturas. Uma fileira de flapes (56) é articulada com o quadro (58), para cobrir e descobrir, seletivamente, as aberturas (48), para controlar o fluxo de descarga descarregado por ele. Uma barra em uníssono arqueada (68) circunda o duto (36) adjacente ao quadro (58) e inclui cames (70) espaçados circunferencialmente entre si, acoplando os seguidores de cames (66) correspondentes fixados nos flapes (56). Um atuador (72) é unido à barra (68) para rotação seletiva dela, entre as primeira e segunda direções opostas, para pivotar os flapes (56) abertos e fechados em cima das aberturas.
