Abstract

LA INVENCION SE REFIERE A UN PROYECTOR ELECTROSTATICO DE PRODUCTO DE REVESTIMIENTO PULVERULENTO QUE COMPRENDE UN CONDUCTO DE ALIMENTACION (2) CON PRODUCTO DE REVESTIMIENTO QUE DESEMBOCA AXIALMENTE EN EL FONDO DE UNA CABEZA DE PROTECCION ROTATIVA (3), CARACTERIZADO EN QUE UNA FICHA (30) MONTADA AXIALMENTE SOBRE DICHA CABEZA DE PROYECCION ESTA EN CONTACTO ELECTRICO CON UNA PARTE FIJA (26) DEL PROYECTOR, SIENDO LA PARTE FIJA ELECTRICAMENTE CONDUCTORA Y ESTANDO CONECTADA A UN CIRCUITO DE ALIMENTACION (22, 23, 24, 25) DE ALTA TENSION. GRACIAS A LA INVENCION, LA ALTA TENSION PUEDE APLICARSE SOBRE EL EJE DE ROTACION (XX`) DE LA CABEZA DE PROYECCION EN UN PUNTO COMPATIBLE CON LA UTILIZACION DE UNA ALIMENTACION CENTRAL DE LA CABEZA DE PROYECCION DE PRODUCTO DE REVESTIMIENTO.THE INVENTION IS RELATED TO AN ELECTROSTATIC PROJECTOR OF POWDER COATING PRODUCT THAT INCLUDES A SUPPLY PIPE (2) WITH A COATING PRODUCT THAT UNLOCKS AXIALALLY IN THE BACKGROUND OF A ROTATING PROTECTION HEAD (3), WHICH IS CHARACTERIZED AXIALLY MOUNTED ON SUCH A PROJECTION HEAD IS IN ELECTRICAL CONTACT WITH A FIXED PART (26) OF THE PROJECTOR, THE FIXED PART BEING ELECTRICALLY CONDUCTIVE AND CONNECTED TO A HIGH VOLTAGE CIRCUIT (22, 23, 24, 25). THANKS TO THE INVENTION, THE HIGH VOLTAGE CAN BE APPLIED ON THE PROJECTION HEAD AXIS OF ROTATION (XX`) AT A POINT COMPATIBLE WITH THE USE OF A CENTRAL FEEDING FOR THE PROJECTION HEAD OF A COATING PRODUCT.
