Patent ID: 8352197

Claim:
An arrangement for monitoring and presenting the status of an electrolytic process such as an metal electrorefining process or an metal electrowinning process in an electrolytic cell ( 1 ), said arrangement comprising at least one sensor ( 3 ) arranged in connection with the electrolytic cell ( 1 ) for regularly and repeatedly measuring at least one process parameter of the electrolytic process, a data processing device ( 6 ) comprising data processing means ( 7 ) for interpreting the process parameters, regularly and repeatedly measured by the sensor ( 3 ), and for establishing status information describing the status of the electrolytic process in the electrolytic cell ( 1 ) by utilizing the process parameters regularly and repeatedly measured by the sensor ( 3 ), a process parameter transmission system ( 16 ) for transmitting the process parameters, regularly and repeatedly measured by the sensor ( 3 ), from the sensor ( 3 ) to the data processing device ( 6 ), and an indicator device ( 9 ) arranged in connection with the electrolytic cell ( 1 ) for indicating the status of the electrolytic process in the electrolytic cell ( 1 ), characterized by a return channel arrangement ( 8 ) for transmitting the status information describing the status of the electrolytic process in the electrolytic cell ( 1 ), established by the data processing means ( 7 ) of the data processing device ( 6 ), from the data processing device ( 6 ) to the indicator device ( 9 ) arranged in connection with the electrolytic cell ( 1 ), and in that the indicator device ( 9 ) comprises presentation means ( 10 ) for presenting the status information describing the status of the electrolytic process in the electrolytic cell ( 1 ), established by the data processing means ( 7 ) of the data processing device ( 6 ), in that the indicator device ( 9 ) is arranged to receive the status information established by the data processing means ( 7 ) of the data processing device ( 6 ) and to present the status information describing the status of the electrolytic process in the electrolytic cell ( 1 ), established by the data processing means ( 7 ) of the data processing device ( 6 ), with the presentation means ( 10 ) in that the process parameter transmission system ( 16 ) comprises a first electronic device ( 2 ), which is in communication with at least one sensor ( 3 ) for receiving process parameters from at least one sensor ( 3 ), and which is arranged to transmit process parameters, and a second electronic device ( 5 ), which is in communication with several first electronic devices ( 2 ) for receiving process parameters from several first electronic devices ( 2 ), and which is arranged to transmit process parameters to the data processing device ( 6 ), and in that the indicator device ( 9 ) is a cell specific indicator device that is configured to present only the status of the electrolytic cell ( 1 ) in connection which the indicator device ( 9 ) is arranged.
