Problems solved by technology

[0002] In the current vacuum ladle, the nozzle, aluminum suction pipe and aluminum outlet are welded and fixed on the ladle body, the hoisting assembly is connected to the frame, the frame is equipped with a transmission mechanism, and the locking device on the ladle cover adopts the original pressure beam type eccentric compression , Poor self-locking property, easy to loosen, the upper and lower heads of the package are hot-pressed, and the surface of the head is prone to produce an oxide layer. The bending strength reduces the service life. The material of the aluminum suction tube is HT20, which is not resistant to high temperature and is easy to burn.

Description

Technical field: [0001] The invention relates to the field of packaging machinery, in particular machinery for the transport of liquids. Background technique: [0002] In the current vacuum ladle, the nozzle, aluminum suction pipe and aluminum outlet are welded and fixed on the ladle body, the hoisting assembly is connected to the frame, the frame is equipped with a transmission mechanism, and the locking device on the ladle cover adopts the original pressure beam type eccentric compression , poor self-locking property, easy to loosen, the upper and lower heads of the package are hot-pressed, and the surface of the head is prone to produce an oxide layer. After the steel plate is heated, the internal crystal phase structure changes, and internal stress is easily generated. The bending strength reduces the service life. The material of the aluminum suction tube is HT20, which is not resistant to high temperature and is easy to burn. Invention content: [0003] The purpose ...
