Description

Technical Field

[0001] The present invention relates to the technical field of aluminum electrolysis detection devices, and in particular to an automatic monitoring device for current distribution of an anode guide rod of an aluminum electrolysis cell and a method for using the same. Background Art

[0002] At present, the electrolytic aluminum industry at home and abroad is shifting towards large-scale and high-power, and the current quota required for a single tank has gradually increased from the 300KA series to the 600KA series. In the production process of electrolytic aluminum, the anode current distribution is an important factor affecting production stability. Due to the limitations of the current electrolytic aluminum production process, the anode carbon block will heat up when the current flows through the anode. Once overheating occurs, depolarization may occur. If it is not handled in time, depolarization will to a certain extent lead to a vicious cycle and cause greater production accidents. At present, the control of anode current distribution in the existing electrolytic aluminum cell production at home and abroad is mostly done manually. Each team arranges at least two people to measure the anode guide rods one by one using a steel chisel connected to a multimeter, and judge the operation of the anode guide rods by the multimeter value. Generally, an electrolytic cell contains 24 to 48 groups of anodes, and a series has about 100 electrolytic cells. Such manual measurement has a long measurement cycle, and the data are not measured in the same period during the manual measurement process, so there is no horizontal comparison. The human factor accounts for a large proportion of manual measurement, and there is a lack of guarantee for the accuracy and precision of the data. In addition, the electrolytic aluminum production environment is poor, and the heat radiation, high magnetic field and dust in the workshop are harmful to people, which cannot be ignored. In recent years, some domestic aluminum plants have developed monitoring devices installed behind the anode guide rods to solve the problem of current distribution monitoring. However, in order to deal with problems such as aluminum output and anode consumption during the production process of the electrolytic cell, the anode guide rods need to be adjusted frequently, or the anodes need to be replaced. Such frequent operations cause deformation and damage to the measuring points of such monitoring devices, and the contact with the guide rods cannot be guaranteed, resulting in abnormal measurement data.

[0003] Therefore, the art is in urgent need of a device and method for automatically monitoring the current distribution of the anode guide rods of an aluminum electrolytic cell, so as to timely monitor the anode current distribution, analyze the changing trend, make timely adjustments, and ensure stable production of electrolytic aluminum.

[0048] Embodiment 2

[0049] This embodiment provides a method for using the device for automatically monitoring current distribution of anode guide rods of an aluminum electrolysis cell described in Embodiment 1, comprising the following steps:

[0051] Step 2: After the device is installed and tested, adjust the position of the wiring nut 17, pass the wiring terminal of the wire 8 through the wiring stud 16 at the tail end of the threaded rod 1, and lock and compact it with the wiring nut 17 to fix the wire 8, complete the connection between the measuring point threaded rod 1 and the circuit board 5, and then test the conductivity between the measuring point threaded rod 1 and the circuit board 5.
