Abstract

Il dispositivo di cui al trovato è atto alla lavorazione orafa di vuotatura della canna mediante acido, preferibilmente nitrico, che viene fatto passare con continuità da una prima cisterna (4) ad una cisterna (1) posta superiormente rispetto alla prima e da questa nuovamente nella prima cisterna.Al termine della fase di dissoluzione dell'anima in rame, i gas acidi che si sprigionano vengono convogliati entro un'ulteriore cisterna (12) contenente una soluzione basica; quest'ultima viene convogliata entro la cisterna (1) in modo da ottenere il lavaggio degli oggetti su cui si è operato.Al termine di questa operazione la cisterna (1) viene svuotata, ciò che consente di estrarre gli oggetti dalla suddetta senza alcun problema; un apposito impianto provvede inoltre ad estrarre con continuità i fumi che si generano nel corso della lavorazione, provvedendo inoltre a neutralizzarli, per poterli immettere senza problemi nell'atmosfera.The device according to the invention is suitable for the goldsmithing process of emptying the barrel by means of acid, preferably nitric, which is made to pass continuously from a first tank (4) to a tank (1) located above the first and from it again in the first cistern. At the end of the dissolution phase of the copper core, the acid gases that are released are conveyed into a further cistern (12) containing a basic solution; the latter is conveyed into the tank (1) so as to obtain the washing of the objects on which it was operated.At the end of this operation the tank (1) is emptied, which allows you to remove the objects from the aforementioned without any problem ; a special system also continuously extracts the fumes that are generated during the process, also neutralizing them, so that they can be introduced into the atmosphere without problems.
