Abstract

LA INVENCION SE REFIERE A UN METODO Y A UN APARATO PARA LIMPIAR UN TAMBOR FILTRADOR O UN CILINDRO UTILIZADO PARA CONDENSAR FANGO DE CAL EN DICHO TAMBOR FILTRADOR EL FANGO DE CAL ESTA CONDENSADO SOBRE UNA CAPA FILTRADORA DE FANGO DE CAL FORMADA SOBRE LA SUPERFICIE DE UN TAMBOR FILTRADOR PARCIALMENTE SUMERGIDO EN UN VASO QUE CONTIENE EL FANGO DE CAL. ES CARACTERISTICO DEL METODO DE LA INVENCION QUE, ANTES DE QUE EL CONCENTRADO DE FANGO DE CAL SE ELIMINE CON UN RASCADOR DE LA SUPERFICIE DE UNA CAPA PRECUBIERTA, SE DESPEGUE UNA BANDA DE FANGO DE CAL DE LA CAPA DE FANGO DE CAL CONDENSADO CON AL MENOS UN CHORRO DE LIQUIDO DE BAJA PRESION QUE SE MUEVE EN LA DIRECCION LONGITUDINAL DEL TAMBOR. ES CARACTERISTICO DEL APARATO DE LA INVENCION QUE SE SITUE AL MENOS UNA BOQUILLA (36, 38) EN LA DIRECCION ROTACIONAL DEL TAMBOR ANTES DE QUE EL RASCADOR SEPARE EL CONCENTRADO DE FANGO DE CAL Y QUE EL APARATO COMPRENDE, ADEMAS DE DICHA BOQUILLA (36, 38), UNA BOQUILLA DE CHORRO (34) PARA HACER MAS FINA LA CAPA PRERECUBIERTA.
