Description

Technical Field

[0001] The invention relates to the field of cooling water jackets for metal smelting, and in particular to a water jacket assembly structure. Background Art

[0002] Copper water jacket is a kind of copper cooling water jacket. In the metal smelting industry, the discharge port of flash furnace to discharge the melt generally adopts the combination of copper water jacket and lining brick, that is, the box-shaped water jacket is embedded with refractory brick structure, and the melt is discharged from the lining and the central channel of the panel water jacket.

[0003] The prior art water jacket assembly structure includes a square box-shaped embedded water jacket for accommodating refractory bricks, a panel water jacket is arranged at the opening of the embedded water jacket, the panel water jacket is pressed against the inner lining surface and assembled with the embedded water jacket, and the assembly method is to respectively open threaded holes at the four corners of the panel water jacket and the side wall of the embedded water jacket, and then connect the two by bolts. A radial pin hole is opened on the bolt, and the pin is inserted to prevent the bolt from falling off.

[0004] Copper water jackets usually work in high temperature environments for a long time, and bolts are usually made of steel, which has a different thermal expansion coefficient from the copper material of the water jacket. They are usually installed tightly during assembly at room temperature. Once the copper water jacket is heated, the bolts and the copper water jacket will be squeezed. Even if the bolts are cooled after squeezing, an interference fit will occur between the bolts and the bolt holes, making it extremely difficult to remove the bolts. At the same time, rust on the bolts will also make it difficult to remove them. If too much force is used during removal, the bolts will break along the root, and the bolts left inside the water jacket will be more difficult to remove. Even if the bolts can be taken out, the copper threads inside the water jacket will be damaged. The inability to install new bolts will also cause the panel water jacket to be unable to be fixed, making the water jacket unusable. Summary of the invention

[0005] The object of the present invention is to provide a water jacket assembly structure which can prevent the water jacket and bolts from being stuck due to heat.

[0006] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a water jacket assembly structure, including a square box-shaped copper embedded water jacket for accommodating refractory bricks, a copper panel water jacket is arranged at the opening of the embedded water jacket, and U-shaped notches are respectively arranged on the opposite side plate edges of the panel water jacket, the U-shaped notches are connected with the corresponding U-shaped openings arranged on the embedded water jacket, and steel bolts and nuts are connected through the U-shaped notches and the U-shaped openings.

[0007] In the above scheme, even if the bolts are corroded and the threads are damaged, they can be disassembled by directly destroying the bolts, and the installation can be completed by directly replacing new bolts without destroying the water jacket structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] A water jacket assembly structure includes a square box-shaped copper embedded water jacket 10 for accommodating refractory bricks, a copper panel water jacket 20 is arranged at the opening of the embedded water jacket 10, and U-shaped notches 21 are respectively arranged on the opposite side edges of the panel water jacket 20. The U-shaped notches 21 are connected with the corresponding U-shaped openings on the embedded water jacket 10, and steel bolts 30 and nuts 31 are connected through the U-shaped notches 21 and the U-shaped openings.

[0011] In the above scheme, since the bolt 30 and the nut 31 are made of the same material, the thermal expansion coefficients of the two are the same. Even if the bolt 30 and the nut 31 expand and contract due to heat, the nut 31 can be easily removed. The bolt is actually stuck in the U-shaped notch 21 and the U-shaped opening. In the open structure, the copper material has a certain elasticity and the bolt can be easily removed from the opening. Even if the U-shaped notch 21 and the U-shaped opening are squeezed and damaged, it does not affect the subsequent replacement of new bolts for installation. Even if the bolt 30 is rusted and the thread is damaged, it can be disassembled by directly destroying the bolt 30. The installation can be completed by directly replacing the new bolt 30 without destroying the water jacket structure.

[0012] The opposite side panels of the panel water jacket 20 are integrally cantilevered to symmetrically arranged cantilevers 22, and the U-shaped notch 21 is provided on the cantilever 22, and the cantilever plate and the U-shaped opening are provided correspondingly to the embedded water jacket 10. The cantilever 22 structure can maintain the integrity of the original water jacket structure, and can complete the technical transformation without destroying the original water jacket performance, while reducing the design difficulty and mold opening difficulty, and reducing the transformation cost, and the cantilever 22 is integrally cast with the water jacket.

[0013] The end plate surface of the cantilever 22 and the cantilever plate near the nut 31 side or the head side of the bolt 30 is provided with a boss 50. The boss 50 can effectively limit the head of the bolt 30 and the nut 31 in radial direction to prevent the bolt 30 from falling off. For disassembly, the bolt 30 can be pried out from the U-shaped notch 21 by rotating the nut 31 to a position higher than the boss 50.

[0014] L-shaped steel clamping plates 40 are respectively arranged on the opposite sides of the embedded water jacket 10, the vertical plate sides of the clamping plates are connected to the embedded water jacket 10, and the horizontal plate sides of the clamping plates are connected to the connection frame. The steel clamping plates 40 can further fix the embedded water jacket 10 and connect the embedded water jacket 10 to the installation position.
