Description

Technical Field

[0001] The utility model relates to the technical field of electrolytic cell maintenance, in particular to a temperature monitoring and cooling device for a side wall of an electrolytic cell. Background Art

[0002] The service life of aluminum electrolytic cells is 2000 days. Under the condition of continuous high-temperature operation, due to technical conditions and improper maintenance of the electrolytic cells, the electrolytic cells will be damaged to varying degrees, especially the cathode of the electrolytic cell is prone to damage. The first manifestation after damage is the continuous rise in the temperature of the three steel bars of the electrolytic cell. If the work area finds that the temperature of the three steel bars of the electrolytic cell has risen, a special person will be deployed to measure the temperature of the three steel bars. If the temperature of the three steel bars exceeds 350 degrees, the electrolytic cell will be listed as a damaged cell under key monitoring. The peak period of monitoring of damaged cells in each work area is more than 5 units. There is a gap in the monitoring of multiple electrolytic cells by one person at the same time. If the measurement interval is too long, it is easy to cause leakage accidents in the electrolytic cell or even cause non-stop accidents in the electrolytic cell. It is necessary to install an online monitoring device. The existing online monitoring device can only perform temperature monitoring and has no cooling function, which needs to be improved.

[0005] As an improvement, the booster water tank and the air pressure tank are connected via a pipeline, and a solenoid valve electrically connected to the controller is provided on the pipeline.

[0006] As an improvement, the spray device and the pressurized water tank are connected via a hose.

[0007] As an improvement, the spray device includes a spray pipe and a plurality of spray heads arranged on the spray pipe.

[0008] Compared with the prior art, the utility model has the following advantages: 1. The thermocouple can monitor the cathode temperature of the electrolytic cell body and feed back the monitoring data to the controller; 2.
