Abstract
"PATENTE DE INVENçãO DE PROCESSO E EQUIPAMENTO PARA RECUPERAçãO DE METAIS NãO FERROSOS CARREADOS EM BORRAS E ESCóRIAS". O sistema de recuperação de metais não ferrosos presentes em borras e escórias objeto desta patente, pertencente ao setor de metalurgia, refere-se a um método e respectivo aparato destinado à recuperação de metal livre presente em borras e escórias quentes resultantes do processamento de metais não ferrosos em temperaturas acima do seu ponto de fusão, sem estas borras ou escórias sejam resfriadas após a serem coletadas. O método consiste na remoção das borras ou escórias diretamente para o interior de um equipamento provido de isolação térmica e meios de controle da sua atmosfera interior e o armazenamento e processamento desse material diretamente no forno de recuperação. Estando o equipamento coletor total ou parcialmente cheio, na etapa seguinte ele é diretamente transportado para uma unidade de tratamento próxima, composta por dispositivos de transferência e um ou mais fornos rotativos selados e com atmosfera controlada, os quais trabalham no acúmulo, revolvimento da borra ou escória e separação e remoção do metal livre. O equípamento empregado na recuperação de metais não ferrosos presente em borras e escórias, objeto desta patente, consiste em um recipiente de coleta com paredes termicamente isoladas, provido de tampa também termicamente isolada e bem ajustada ao corpo do recipiente, dispositivo de içamento e transferência da borra do interior do recipiente para uma calha ajustada à porta de alimentação de um forno de acúmulo e separação.
