[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3This utility model provides a technical solution: It includes a steel cladding shell 1, inside which are sequentially arranged an insulation layer 2, a sealing layer 3, and a permanent layer 4. A working layer 5 is installed inside the permanent layer 4. Limiting blocks 6 are provided on both sides of the outer wall of the working layer 5. Limiting grooves 7 corresponding to the limiting blocks 6 are formed on the inner wall of the permanent layer 4. A cover plate 8 is installed at the upper end of the steel cladding shell 1. A heat insulation plate 9 is provided at the bottom of the cover plate 8. Multiple locking seats 10 are provided on both sides of the cover plate 8. Locking buckles 11 are fixedly installed on the top of both sides of the outer wall of the steel cladding shell 1. Through the cooperative arrangement of the steel cladding shell 1, insulation layer 2, sealing layer 3, permanent layer 4, working layer 5, limiting blocks 6, limiting grooves 7, cover plate 8, heat insulation plate 9, locking seats 10, and locking buckles 11, in use, the locking buckles 11 are opened to remove the working layer 5 inside the intermediate cladding, and then the working layer 5 to be replaced is installed inside the intermediate cladding. Because the limiting block 6 and the limiting groove 7 are set, they can limit the installation and facilitate the installation. Then, the cover plate 8 is placed on the steel ladle shell 1. Then, the cover plate is fixed by the locking buckle 11 and the locking seat 10. At this time, the heat insulation plate will press down on the working layer 5, which facilitates the quick replacement and assembly of the working layer 5 inside the intermediate ladle. The operation is simple. The inner bottom wall of the working layer 5 is fixedly connected to the impact pad 12. The inner bottom wall of the working layer 5 is provided with baffles 13 on both sides of the impact pad 12. The inner bottom wall of the working layer 5 is provided with dams 14 on the opposite side of the two baffles 13. The inner bottom wall of the working layer 5 is provided with water inlets 15 on the opposite side of the two dams 14. The upper end of the cover plate 8 is provided with a liquid inlet 16. The outer walls of the steel ladle shell 1 are fixedly installed on both sides. The outer walls of the reinforcing steel frame 17 are provided with support columns 18 on both sides of the outer walls of the reinforcing steel frame 17.

During use, the locking buckle 11 is opened to remove the working layer 5 from the intermediate ladle, and then the working layer 5 to be replaced is installed inside the intermediate ladle. The limiting block 6 and the limiting groove 7 facilitate installation by limiting the movement. The cover plate 8 is then placed on the steel ladle shell 1, and the cover plate is secured by the locking buckle 11 and the locking seat 10. At this time, the heat insulation plate presses down on the working layer 5, thus facilitating the quick replacement and assembly of the working layer 5 inside the intermediate ladle. The operation is simple.
