Description

Technical Field

[0001] The utility model relates to the technical field of precise aluminum tapping devices for aluminum electrolysis, in particular to a precise aluminum tapping device for aluminum electrolysis. Background Art

[0002] During the aluminum electrolysis process, a vacuum aluminum ladle is placed in an electrolytic cell. Compressed air needs to be introduced into the electrolytic cell to increase the pressure of the electrolyte to a level greater than that of the vacuum ladle, allowing the molten aluminum to flow into the vacuum ladle. This process requires continuous flow of compressed air into the aluminum tapping pipe on the overhead crane. One of the main daily tasks in the aluminum electrolysis industry is aluminum tapping, which requires the use of an aluminum tapping device for operation.

[0003] For example, the Chinese authorized patent with announcement number CN220812645U (a multifunctional overhead crane aluminum discharging device for aluminum electrolysis) includes a gas storage tank and a tube disc device, an air outlet is provided on the circumferential surface of the gas storage tank, and an aluminum discharging tube is connected to the air outlet; the tube disc device includes a receiving mechanism and a tightening device, the receiving mechanism includes a support plate and a roller rotatably arranged on the support plate; the tightening device is arranged on the support plate, and the aluminum discharging tube passes through the tightening device and is wound around the roller. In the utility model, the gas storage tank stores gas through an air compressor and discharges the compressed air from the aluminum discharging tube. When the aluminum discharging task is completed, the compressed air can be stored in the gas storage tank, effectively utilizing the compressed air and reducing the overall power consumption. The aluminum discharging tube extends from the groove and is wound around the roller. The control motor can release and retract the aluminum discharging tube from the roller, and the control electric cylinder can make the slider slide down to compress the aluminum discharging tube and stop the supply of compressed air.

It is easy to have the problem of low aluminum tapping accuracy due to errors in the electrolytic cell aluminum tapping system; therefore, it does not meet the existing needs. For this purpose, we propose an aluminum electrolysis precision aluminum tapping device. Utility Model Content
