Aluminum electrolysis anode distribution current accurate measuring instrument

Abstract

The invention provides an aluminum electrolysis anode distribution current accurate measuring instrument which is beneficial to improving the measurement accuracy of anode currents. The measuring instrument comprises a microprocessor, a signal conditioning circuit, an A / D conversion module, a temperature acquisition module, a communication module, a data storage module and a power module. The signal conditioning circuit is used for processing voltage signals, converting the voltage signals into digital voltage signals through the A / D conversion module and making the digital voltage signals connected to the first input end of the microprocessor. The temperature acquisition module comprises a temperature sensor and a temperature processing module. The temperature processing module is used for converting temperature signals collected by the temperature sensor into digital temperature signals and making the digital temperature signals have access to the second input end of the microprocessor. The microprocessor is used for processing the accessed digital voltage signals and the accessed digital temperature signals, storing processing results into the data storage module and sending the processing results to an upper computer through the communication module. The aluminum electrolysis anode distribution current accurate measuring instrument is applicable to the technical field of aluminum electrolysis.

Description

technical field [0001] The invention relates to the technical field of aluminum electrolysis, in particular to an accurate measuring instrument for anode distribution current of aluminum electrolysis. Background technique [0002] Aluminum electrolysis is a complex electrochemical reaction process, which is subject to the coupling effects of multiple physical fields such as electric field, magnetic field, thermal field, and flow field. The complexity of aluminum electrolysis production conditions and the harsh production environment lead to the lack of methods and equipment for on-line monitoring of the aluminum electrolysis process, and the anode current is a very important data in the aluminum electrolysis production, which is related to various conditions in the aluminum electrolysis production are closely related. Firstly, it can directly reflect the anode overcurrent phenomenon; secondly, the anode current distribution has a very close relationship with the pole distan...
