Background
The vacuum ladle is a large sealed container made of refractory lining material and with steel casing, and has negative pressure generator to produce certain vacuum to draw molten aluminum from the electrolyzer and transport it to other places. After the vacuum ladle is used for a certain time, a large amount of impurities can be accumulated in the vacuum ladle, so that the vacuum ladle needs to be overhauled regularly to clean the impurities in the vacuum ladle in order to improve the capacity of the vacuum ladle. When overhauling, the ladle cover needs to be opened, so that the asbestos sealing strip between the ladle cover and the ladle body also needs to be removed, and the asbestos sealing strip is installed after overhauling. In the prior art, after overhauling and reinstallation, the vacuum ladle is directly pulled away through a transport vehicle, the tightness of the vacuum ladle is not measured, the vacuum ladle is often pulled to an electrolytic tank, when aluminum liquid is extracted, the aluminum liquid is found to be unable to be pumped up, and the vacuum ladle is returned to a workshop for detecting and maintaining the tightness of the vacuum ladle.

Furthermore, the sealing cover is made of rubber.
Compared with the prior art, the invention has the following advantages:
according to the invention, the ejector can be used for extracting the air in the vacuum ladle, and the vacuum degree detection is carried out on the overhauled vacuum ladle through the negative pressure meter, so that the reworking phenomenon is prevented, the production efficiency is improved, and the labor intensity of workers is reduced;
according to the invention, the air discharged from the vacuum ladle is discharged into the container, and the dust in the air in the ladle is filtered through the water, so that the dust in the ladle is prevented from being diffused in a workshop, and the working environment of the workshop is protected;
the sealing cover is made of rubber, so that the detection sensitivity of the vacuum degree in the ladle can be enhanced; if the vacuum ladle has good tightness, the negative pressure generated at the detection tube is larger, and the sealing cover made of rubber material can be tightly adsorbed at the end part of the detection tube, so that the end part of the detection tube is sealed; if the vacuum ladle is not good in tightness, air can enter in different places, so that negative pressure generated at the detection tube is reduced, suction force to the sealing cover is also reduced, tightness at the detection tube is further reduced, amplification of detection results is finally realized, and the effect of improving detection sensitivity is achieved.
