Tank controller protective device for preventing anode separation

Abstract

The invention provides a tank controller protective device for preventing anode separation. The tank controller protective device comprises a MCU unit, an AD conversion module, a voltage display module, an external reset signal module, an alarm signal output module, an LED indicating lamp, a buzzer, an optically-isolated solid-state relay. The AD conversion module is in signal connection with the output end of a voltage detecting module used for detecting the voltage of an aluminum electrolytic tank and disposed in the aluminum electrolytic tank. The input end of the MCU unit is connected with the output end of the AD conversion module. The output end of the MCU unit is connected with the voltage display module, the external reset signal module, the alarm signal output module, and the optically-isolated solid-state relay. The alarm signal output module is connected with the LED indicating lamp and the buzzer. The tank controller protective device has a tank voltage detection function, may substitutes for an original tank voltmeter, may output an on-off signal on this basis, controls a shunt release to release an anode elevating loop air switch in order to prevent anode elevation.

Description

technical field [0001] The invention belongs to the technical field of aluminum smelting, and in particular relates to a pole separation protection device for a slot control machine. Background technique [0002] Aluminum electrolytic production requires real-time dynamic monitoring of the aluminum electrolytic cell in production to achieve a relatively stable material balance and thermal balance, so that the electrolytic cell can have higher current efficiency and lower power consumption, which only rely on manual It is extremely difficult to complete, which requires a special control device to monitor the aluminum electrolytic cell in real time, collect, analyze, and control various data of the aluminum electrolytic cell in real time, so as to better ensure the safe operation of the electrolytic cell. The key control equipment of the tank - the tank control machine came into being. With the development of science and technology, qualitative changes have taken place in the ...

Problems solved by technology

[0003] The tank control machine is one of the important equipments that must be used in the production process of aluminum electrolysis. Each electrolytic cell is equipped with one. Electrolyte splashing, short-circuit over-voltage breakdown damage, and even lead to damage to the rectifier device, causing a series of shutdowns and causing huge damage. Our company is an electrolytic aluminum production enterprise and uses a large number of slot control machine control equipment to ensure the safety of electrolytic series equipment In operation, it is necessary to add an electrolytic cell polarity protection device to make up for the blind spot of the existing cell control machine, and it can also be used to replace the existing cell pressure gauge
