Abstract

"DISPOSITIVO PARA UMA DILUIçãO CONTINUAMENTE OPERADA DE UMA AMOSTRA DE PASTA FLUIDA". A presente invenção se refere a um dispositivo para uma diluição continuamente operada de uma amostra de pasta fluida, dispositivo através do qual a amostra de pasta fluida é alimentada diretamente para um analisador ótico continuamente operado, tal como um analisador de tamanho de grão. O referido dispositivo compreende elementos para alimentação da amostra de pasta fluida, elementos para alimentação de líquido de diluição e elementos para remoção de sólidos contidos na pasta fluida, bem como elementos para descarregamento tanto do líquido contido na pasta fluida e quanto do líquido utilizado para diluição. Em concordância com a presente invenção, o referido dispositivo está caracterizado pelo fato de que compreende pelo menos uma câmara se estreitando descendentemente (2, 31) que está conectada para a célula de mensuração de analisador (3, 34) de maneira que duas paredes opostas (10, 32) da câmara (2, 31) estão essencialmente paralelas tanto com respeito uma em relação a outra e quanto com respeito para as respectivas paredes (21, 35) da célula de mensuração de analisador (3, 34).
