Abstract

"MéTODO E APARELHO DE PROCESSAMENTO ULTRA-SÈNICO COM TRANSDUTORES DE MúLTIPLAS FREQüêNCIAS". São revelados um aparelho e método de processamento ultra-sênico, que incluem múltiplos transdutores de pelo menos duas freqüências ressonantes diferentes que fornecem energia ultra-sónica a um tanque cheio de líquido contendo componentes a ser limpos ou processados ultra-sonicamente. Os transdutores são arranjados em padrões triangulares eqüilaterais ao longo de linhas diagonais em uma parede do tanque, de maneira que cada transdutor tenha um transdutor adjacente de uma freqüência diferente. Alternativamente, o aparelho inclui um ou mais transdutores tipo haste tendo freqüências ressonantes diferentes, de maneira que o aparelho forneça uma mistura de várias freqüências de energia ultrasónica ao tanque. Um outro aspecto da invenção envolve selecionar transdutores com freqüências ressonantes diferentes, que estão fora de uma subfaixa excluída, e energizar os transdutores por meio de um sinal de excitação que varre as freqüências ressonantes dos transdutores e a subfaixa excluída.
