The invention discloses a metal oxide anode life measuring device which comprises an electrolysis power source, metal oxide anodes, cathodes, an upper computer, a controller, a data acquisition system, relays, a metering pump, a circulating pump and signal conversion modules. The cathodes and the to-be-measured metal oxide anodes are arranged in sulfuric acid solution in sulfuric acid solution tanks; the upper computer is connected with the electrolysis power source, the controller and the data acquisition system; positive and negative electrodes of the electrolysis power source are respectively connected with the metal oxide anodes and the cathodes; the controller is electrically connected with the relays, the metering pump and the circulating pump; the data acquisition system is connected with the signal conversion modules and a sulfuric acid concentration measuring instrument. The signal conversion modules are respectively connected with the metal oxide anodes and the cathodes. The metal oxide anode life measuring device has the advantages that voltages between the metal oxide anodes and the cathodes can be automatically measured by the metal oxide anode life measuring device, the failed metal oxide anodes can be shielded, the failure time of the to-be-measured metal oxide anodes can be recorded, the current stability can be guaranteed for the to-be-measured metal oxide anodes in test procedures, accordingly, the electrolysis power source can be prevented from being operated under full-load conditions in the test procedures, and power sources can be protected.

Description

technical field [0001] The invention relates to a metal oxide anode life measuring device, which belongs to the technical field of metal oxide anodes. Background technique [0002] Existing measurement methods generally use manual measurement of the voltage between the cathode and anode, manually cut off the failed anode and add distilled water to the sulfuric acid solution. [0003] Since the life test of the metal oxide anode is a continuous test, the life span is variable, the shortest may be a few hours, the longest may be several months, it is impossible to be manned all the time, and the failure time of the metal oxide anode is uncertain, Upon failure, the resistance of the metal oxide anode increases rapidly. If the metal oxide anode is left unattended when it fails, the supply voltage will rapidly increase to the full load of the supply, and the current will decrease to a level that cannot meet the current required for the life test. Since the metal oxide anodes to...
