Problems solved by technology

However, there is no monitoring equipment and technical monitoring measures to assist in this operation process. Only relying on manual control of the anode lifting time, this method has great potential safety hazards. If the manual anode is misoperated or the contactor appears Adhesion failure, at this moment the anode cannot be controlled at all, which will cause serious accidents of slotting or pressing slots, and bring huge economic losses

Embodiment 1

[0034] purpose of the invention

[0035] When the slot control machine is performing process control, you can set the slot control machine to work in automatic mode or manual mode through the switch button on its panel. According to the requirements of the electrolysis process, in order to make the cell voltage quickly reach the required target value, it is often necessary to manually adjust the anode to achieve the goal. However, there is no monitoring equipment and technical monitoring measures to assist in this operation process. Only relying on manual control of the anode lifting time, this method has great potential safety hazards. If the manual anode is misoperated or the contactor appears Adhesion failure, at this moment the anode cannot be controlled at all, which will cause serious accidents of groove pulling or groove pressing, and bring huge economic losses. In order to improve the safety and reliability of the tank control machine and eliminate the potential saf...

Embodiment

[0049] This technical method is simple and not restricted by the working environment. It makes up for the defects of the tank control system in the manual anode lifting operation, and reduces the probability of slotting accidents in the anode lifting operation. After nearly half a year of actual operation, the system is reliable. The permanent design has withstood the test of complex industrial environments such as strong electromagnetic interference and power frequency signal interference. The safety of manual anode lifting operation has been greatly improved, providing a strong guarantee for the safe and stable operation of electrolysis production.

Abstract

The invention relates to the technical field of electrical control, and in particular relates to a method for protecting the lifting safety of an electrolytic cell controller anode. The method for protecting the lifting safety of the electrolytic cell controller anode comprises manual anode operation safety protection and timer function shielding during electrolytic cell controller lift busbar operation. The method comprises the following steps: 1, a manual anode operation safety protection step; and 2, a timer function shielding step during electrolytic cell controller lift busbar operation. The method for protecting the lifting safety of the electrolytic cell controller anode is simple to operate, is not limited by working environments and makes up the defect of the manual anode lifting operation aspect of an electrolytic cell control system, and the probability of electrolytic cell shifting accidents during the anode lifting operation is reduced; and half-year practical operation proves that the reliability design of a system passes through the tests of complicated working environments of strong electromagnetic interference, power frequency signal interference and the like, the safety of the manual anode lifting operation is greatly improved, and a powerful guarantee is provided for the safe and reliable operation of electrolytic production.

Description

technical field [0001] The invention relates to the technical field of electrical control, in particular to a safety protection method for the anode lift of an aluminum electrolytic cell control machine. Background technique [0002] The tank control machine is the core equipment for process control in aluminum electrolysis production. It can collect the tank voltage and tank current of the electrolytic tank, receive various manual operation signals of the panel switch board and various detection signals of the tank control system. After analysis and calculation, corresponding functions such as shelling, feeding, fluoride salt addition, anode lifting, effect alarm, etc. are performed to complete various controls on aluminum electrolysis production. Anode lifting operation is one of the functions, and it is also the One of the major hazards in the smelting production process. Once the anode lifting system is out of control, there will be serious accidents in the electrolytic ...
