Abstract

EL DISPOSITIVO COMPRENDE, AL MENOS, UNA SUPERFICIE DE CRIBA (3) PERFORADA A TODO SU ALREDEDOR Y QUE PUEDE GIRAR, EN LA CUAL, AL MENOS, SE HA DISPUESTO UNA ESPIRAL (11) EN EL LADO DE SUMINISTRO DEL MATERIAL DE LA SUPERFICIE DE CRIBA (3), DONDE DICHA ESPIRAL (11) TIENE UNA SUPERFICIE DE CONTACTO LISA (12) CON LA SUPERFICIE DE CRIBA (3). DE ACUERDO CON EL INVENTO, SE SUMINISTRAN MEDIOS PARA MOVER LA ESPIRAL (11) QUE NO PUEDE GIRAR, ENTRE UNA POSICION DE GUIA, EN LA QUE ESTA SUSPENDIDA DURANTE LA OPERACION NORMAL A UNA CORTA DISTANCIA SOBRE LA SUPERFICIE DE CRIBA, Y UNA POSICION DE LIMPIEZA EN LA QUE SE PRESIONA INTERMITENTEMENTE CONTRA LA SUPERFICIE DE CRIBA, LIMPIANDO LAS PERFORACIONES DE LA MISMA DEL PRODUCTO QUE HA QUEDADO AGARRADO EN DICHAS PERFORACIONES. DE ACUERDO CON LA FORMA MAS ADECUADA DEL INVENTO, LA ESPIRAL (11) SE SUSPENDE DE UN PORTADOR (13) QUE TIENE UNA GARRA (16) EN FORMA DE ESTRELLA QUE ES CONCENTRICA CON EL EJE DE ROTACION DE LA SUPERFICIE DE CRIBA, EL PORTADOR (13) SE COMPONE DE UN ANILLO INTERIOR (14) Y UN ANILLO EXTERIOR (15) ENTRE LOS QUE LA GARRA (16) ESTA MONTADA, DICHO PORTADOR (13) SE ASEGURA A LA ESTRUCTURA FIJA (2) DEL DISPOSITIVO DE CRIBA ENTRE LA POSICION DE GUIA Y LA POSICION DE LIMPIEZA.THE DEVICE INCLUDES, AT LEAST, A SCREENING SURFACE (3) PERFORATED AROUND ITS SURROUNDING AREA AND WHICH CAN ROTATE, IN WHICH, AT LEAST, A SPIRAL (11) HAS BEEN ARRANGED ON THE SUPPLY SIDE OF THE SURFACE MATERIAL SCREEN (3), WHERE SUCH SPIRAL (11) HAS A SMOOTH CONTACT SURFACE (12) WITH THE SCREEN SURFACE (3). ACCORDING TO THE INVENTION, MEANS ARE PROVIDED TO MOVE THE SPIRAL (11) WHICH CANNOT ROTATE, BETWEEN A GUIDE POSITION, WHICH IS SUSPENDED DURING NORMAL OPERATION AT A SHORT DISTANCE ON THE SCREEN SURFACE, AND A POSITION OF CLEANING IN WHICH PRESSURE IS INTERMITTENTLY AGAINST THE SCREEN SURFACE, CLEANING THE PERFORATIONS OF THE SAME PRODUCT THAT HAS BEEN GRIPPED IN SUCH PERFORATIONS. ACCORDING TO THE MOST SUITABLE FORM OF THE INVENTION, THE SPIRAL (11) IS SUSPENDED FROM A CARRIER (13) THAT HAS A CLAW (16) IN THE FORM OF A STAR THAT IS CONCENTRIC WITH THE ROTATING AXIS OF THE SCREEN SURFACE, THE CARRIER (13) IT IS COMPOSED OF AN INTERIOR RING (14) AND AN EXTERIOR RING (15) AMONG WHICH THE CLAW (16) IS MOUNTED, SUCH CARRIER (13) IS SECURED TO THE FIXED STRUCTURE (2) OF THE SCREEN DEVICE BETWEEN THE GUIDE POSITION AND CLEANING POSITION.
