Abstract
"DISPOSITIVO E PROCESSO PARA SEPARAçãO DE PURIFICAçãO DE CRISTAIS DE SUA SUSPENSãO NO BANHO CRISTALINO IMPURO, USO DE UM DISPOSITIVO". A invenção diz respeito a um dispositivo para realizar a separação de purificação de cristais de sua suspensão em um banho cristalino impuro, compreendendo uma coluna cilíndrica oca (45) que delimita uma zona de concentração e uma zona de lavagem. Vários tubos de filtro (7) estendem-se da primeira extremidade da coluna (45) e através da coluna enquanto são paralelos ao eixo do cilindro. Um filtro (6) é colocado na parede de um tubo de filtro (7) e forma a única conexão direta entre o interior do tubo e o interior da coluna (45). A zona de concentração é terminada na primeira extremidade da coluna localizada oposta aos filtros (6) por um fundo provido com aberturas. Uma primeira porção das aberturas do fundo (12) passa nos tubos de filtro (7) simultaneamente enquanto passa no lado de abertura oposto, em um dispositivo (5) para descarregar o banho cristalino impuro. Uma segunda porção das aberturas do fundo (12) é conectada a um espaço distribuidor (18) no qual a suspensão de cristal a ser separada é alimentada e que tem um auxiliar distribuidor tal como um cone distribuidor (1).
