Insulation foaming structure and method for a tank container

A tank container insulation foaming structure, comprising:

• a press molding module for foaming;
• and
• a clamping fixation module for securing the press molding module;
• wherein the press molding module comprises a flat plate that connects with the tank container (9), an arc plate (2) provided on the flat plate (1), and a connection plate (3) used to connect the flat plate (1) with the arc plate (2);
• a foaming space (10) is formed between the arc plate (2) and the tank container (9);
• wherein the clamping fixation module comprises a fixed frame (4) for securing the flat plate (1), a compression rod (6) for fastening the fixed frame (4), and connecting components that connect the compression rod (6) with the tank container (9);
• the fixed frame (4) is connected to the press molding module and fastens the fixing frame (4) to the tank container (9) by the compression rod (6), the compression rod (6) is connected to the tank container (9) through connecting components:
• the foaming space (10) has an insulating layer formed by the foaming material.
