The container only processes the upper and lower flange end faces, and the inner wall is not processed. When welding the container, a circular ring plate is used as a simple tooling to support and position the inner wall of the container.

[0003] At present, three 8-shaped circular plates are often used for simple positioning of the container body during container assembly welding. However, since the circular plates are integral, the shrinkage of the container welding makes it impossible to adjust the circular plates in the height direction of the body, and it is also inconvenient to remove them. The deformation is large when the two bodies are butt-welded and the body and flange are welded. Especially near the opening of the body, the roundness and straightness of the body are not ideal, and the expected effect cannot be achieved. This ultimately affects the gap between the container and the middle paddle, affecting the stirring effect. Summary of the invention
