Detailed Implementation

[0024] To clearly illustrate the technical features of this solution, the following detailed implementation method, in conjunction with its accompanying drawings, will be used to describe the solution.

[0025] A vacuum degassing furnace degassing residue collection structure includes a cold water pan 1 and a slag receiving pan 2. The slag receiving pan 2 is located at the bottom of the cold water pan 1 and is detachably and fixedly connected to the cold water pan 1. A pressure gauge port 9 is fixedly connected to the side wall of the slag receiving pan 2 and communicates with its inner cavity. The pressure gauge port 9 is connected to a pressure gauge, and the pressure inside the slag receiving pan 2 is measured by the pressure gauge.

[0026] A support and adjustment assembly 3 connects the cold water pan 1 and the slag receiving pan 2. The support and adjustment assembly 3 includes a foot support 7 disposed between the cold water pan 1 and the slag receiving pan 2. Multiple adjusting screws 5 are evenly threaded around the foot support 7, and the bottom of each adjusting screw 5 is fixedly connected to a foot 6. Locking nuts 8 are threaded onto each adjusting screw 5 and engage with the upper end of the foot 6 and the upper and lower ends of the foot support 7. The height of the collecting structure can be adjusted by rotating each adjusting screw 5 to facilitate the connection between the collecting structure and the bottom of the vacuum degassing furnace chamber tube.

[0027] The foundation support 7 has a through hole 24 in its middle, the diameter of which is larger than the outer diameter of the cold water pan 1. The bottom of the cold water pan 1 is located inside the through hole 24, and a flange plate 18 is fixedly connected to the side wall of the cold water pan 1. A limiting step 22 that matches the upper edge of the through hole 24 is provided on the bottom surface of the flange plate 18, thereby limiting the position of the cold water pan 1. The bottom surface of the flange plate 18, the side wall of the cold water pan 1, and the bottom surface of the cold water pan 1 form a stepped structure. A flange plate 15 is fixedly connected to the top of the slag receiving pan 2, and the outer diameter of the flange plate 15 is smaller than the diameter of the through hole 24. The flange plate 18 and the flange plate 15 are fixedly connected by fastening bolts 14. The inner edge of the flange plate 15 is provided with a limiting step 25 that cooperates with the step structure. The relative position between the cold water pan 1 and the slag receiving pan 2 is limited by the cooperation between the step structure and the limiting step 25. A slag receiving pan sealing ring 23 is installed between the bottom surface of the cold water pan 1 and the limiting step 25. The slag receiving pan sealing ring 23 ensures the sealing vacuum performance.

[0028] The cooling water pan 1 has a cooling water inlet 10 and a cooling water outlet 11 fixedly connected to opposite ends of its sidewall, with the cooling water inlet 10 being lower than the cooling water outlet 11. The inner wall of the cooling water pan 1 has a cooling cavity 21 that communicates with the cooling water inlet 10 and the cooling water outlet 11. The sidewall of the cooling water pan 1 also has an air inlet 12 that communicates with its inner cavity.

[0029] A cold water pan cover 4 is provided above the cold water pan 1. A flange plate 3 19 is fixedly connected to the top of the cold water pan 1. The bottom of the cold water pan cover 4 has a stepped structure. A limiting step 3 20 that cooperates with the stepped structure is opened on the inner side of the flange plate 3 19. A cold water pan fastening sealing ring 17 is installed between the lower end of the cold water pan cover 4 and the limiting step 3 20. A cold water pan sealing ring 16 is installed on the upper end of the inner wall of the cold water pan 1. The sealing vacuum performance is ensured by the deformation of the cold water pan fastening sealing ring 17 and the cold water pan sealing ring 16. The flange plate 3 19 and the cold water pan cover 4 are fixedly connected by fastening bolts 14. Multiple support bolts 13 are evenly threaded around the flange plate 3 19 and the cold water pan cover 4. The support bolts 13 are pressed against the bottom of the vacuum degassing furnace cavity tube to ensure the installation firmness of the entire collection structure.

[0030] The collection structure of this utility model is installed at the bottom of the vacuum degassing furnace cavity tube, and the overall height of the collection structure can be adjusted by rotating the adjusting screw 5 to ensure that the collection structure is in a suitable position. The cold water pan 1 serves as a cooling component, which can reduce the temperature of the metal residue and protect the sealing ring. The metal residue flows down along the inner wall of the cold water pan 1 and the slag receiving pan 2, and finally accumulates at the bottom of the slag receiving pan 2. The slag receiving pan 2 can be easily disassembled and cleaned.

[0031] After degassing in the vacuum degassing furnace, the resulting liquid metal mixture will fall along the pipe walls of the cooling water pan 1 and the slag receiving pan 2 to the bottom of the slag receiving pan 2, where it will solidify. The solidified metal residue will accumulate at the bottom of the slag receiving pan 2. If the pressure gauge shows that the pressure inside the slag receiving pan 2 is too high or the pressure does not change after aeration, the slag receiving pan 2 needs to be removed to clean the metal residue inside. To remove the slag receiving pan 2, simply loosen the fastening bolts 14 and remove the slag receiving pan 2 directly to clean the metal residue inside. The operation is convenient.

[0032] Technical features not described in this utility model can be implemented using existing technology and will not be elaborated here. This utility model is not limited to the specific embodiments described above. Any changes, modifications, additions, or substitutions made by those skilled in the art within the scope of this utility model should also fall within the protection scope of this utility model.
