Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the utility model for which protection is sought, but merely represents the selected embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0031] This embodiment moves the device to the vicinity of the shell of the electrolytic aluminum cell, and can monitor the shell surface temperature through an infrared thermometer.

The blowing pipe is supplied with air by a high-pressure air source connected to the air supply pipe, and the outer surface of the electrolytic cell shell can be blown centrally through the blowing hood, which greatly improves the intelligent air supply effect of the entire device and makes it easy to control and operate. At the same time, a refrigerator is also provided on the blowing pipe to convert the blown air into cold air, thereby improving the cooling effect. The specific implementation is as follows:

When the temperature is too high, the solenoid valve 15 can be controlled to open the blowing pipe 10 and blow air to cool the surface of the shell. The blowing pipe 10 is supplied with air by an external high-pressure air source connected to the air supply pipe 4. The outer surface of the electrolytic cell shell can be blown centrally through the blowing hood 3, which greatly improves the intelligent air supply effect of the entire device and makes it easy to control and operate.
