Abstract
PROCESO Y APARATO PARA FABRICAR CONTRAPESOS PARA LAVADORAS, ASI COMO UN CONTRAPESO RESULTANTE DE DICHO PROCESO Y APARATO, DICHO PROCESO HACIENDO USO DE MATERIALES DE GRAVEDAD ESPECIFICA ALTA COMO DERIVADOS FERROSOS Y MATERIALES DE DESHECHO SIMILARES DE FABRICAS SIDERURGICAS Y SIMILARES. COMPRENDE UNA PRIMERA FASE EN LA QUE DICHO MATERIAL RECICLADO SE RECTIFICA EN UN TAMAÑO DE GRANO GRUESO Y SE HUMEDECE CON AGUA PARA OBTENER UN POLVO SUBSTANCIALMENTE SECO O PARCIALMENTE HUMEDECIDO; UNA SEGUNDA FASE EN LA QUE DICHO POLVO SE SECA Y POSTERIORMENTE SE ENFRIA; UNA TERCERA FASE EN LA QUE DICHO POLVO SE CRIBA PARA SEPARAR LOS GRANOS DEL TAMAÑO DESEADO DE LOS GRANOS QUE TIENEN UN TAMAÑO DIFERENTE, SIENDO ENVIADOS LOS ULTIMOS DE NUEVO AL RECTIFICADO Y A CONTINUACION RECUPERADOS Y ALMACENADOS CON LOS PRIMEROS; UNA CUARTA FASE EN LA QUE DICHO POLVO SE PRENSA Y CEPILLA EN SU SUPERFICIE; UNA QUINTA FASE EN LA QUE UNA ESTRUCTURA PROTECTORA (28) SE SOBREINYECTA EN DICHOS BLOQUES DE POLVOS PRENSADOS (27) CON LA MISMA FORMA Y TAMAÑO QUE EL CONTRAPESO FINAL, QUE A CONTINUACION ES INCORPORADA AL TUBO DE LA LAVADORA, O A UN TAMBOR EXTERIOR DE LA LAVADORA, SIENDO DICHO CONTRAPESO POR ELLO CAPAZ DE PRODUCIRSE EN SERIE A GRAN ESCALA CON BAJO COSTO, MATERIAL DESPERDICIADO O DE DESHECHO DISPONIBLE EN GRANDES SUMINISTROS.PROCESS AND APPARATUS FOR MANUFACTURING COUNTERWEIGHTS FOR WASHING MACHINES, AS WELL AS A COUNTERWEIGHT RESULTING FROM SUCH PROCESS AND APPARATUS, SUCH A PROCESS MAKING USE OF HIGH SPECIFIC GRAVITY MATERIALS AS FERROUS DERIVATIVES AND SIMILAR DISPOSAL MATERIALS. IT INCLUDES A FIRST PHASE IN WHICH SUCH RECYCLED MATERIAL IS RECTIFIED IN A COARSE GRAIN SIZE AND IS DAMPED WITH WATER TO OBTAIN A SUBSTANTIALLY DRY OR PARTIALLY DAMPED POWDER; A SECOND PHASE IN WHICH SUCH POWDER IS DRIED AND THEN COOLS; A THIRD PHASE IN WHICH SUCH POWDER IS SCREENED TO SEPARATE THE GRAINS OF THE DESIRED SIZE FROM THE GRAINS THAT HAVE A DIFFERENT SIZE, THE LAST BEING SENT BACK TO THE RECTIFIED AND THEN RECOVERED AND STORED WITH THE FIRST; A FOURTH PHASE IN WHICH SUCH POWDER IS PRESSED AND BRUSHED ON ITS SURFACE; A FIFTH PHASE IN WHICH A PROTECTIVE STRUCTURE (28) IS OVERINJECTED IN SUCH PRESSED POWDER BLOCKS (27) WITH THE SAME FORM AND SIZE AS THE FINAL COUNTERWEIGHT, WHICH IS THEN INCORPORATED INTO THE TUBE OF THE WASHING MACHINE, OR TO AN EXTERNAL DRUM THE WASHING MACHINE, BEING SAID COUNTERWEIGHT THEREFORE ABLE TO PRODUCE IN SERIES AT A LARGE SCALE WITH LOW COST, WASTE OR DISPOSAL MATERIAL AVAILABLE IN LARGE SUPPLIES.
