Description

Technical Field

[0001] This invention relates to the field of molten iron transfer equipment technology, and in particular to a split-type swing trough. Background Technology

[0002] The swing trough is an important piece of equipment for blast furnace ironmaking and molten iron transfer. Its function is to guide the molten iron flowing out of the trough to any molten iron ladle below the tapping platform.

[0003] Since the swing channel needs to guide the flow of high-temperature molten iron, its structure mainly consists of a shell, high-temperature refractory material, and related connecting mechanisms. The high-temperature refractory material is continuously eroded by the flow of molten iron, leading to its consumption. When the refractory material is exhausted, the swing channel needs to be replaced, and the refractory material inside the shell needs to be recast.

[0004] The current method of replacing swing trenches requires workers to approach the side of the swing trench, attach the hoisting wire rope, disconnect the swing trench from the swing arm, hoist the replaced swing trench, and then reconnect the swing trench to the swing arm and remove the hoisting wire rope. This method requires workers to work at height, and the high temperature environment and limited working space make the disconnection and connection of the swing trench and swing arm difficult, dangerous, and time-consuming.

[0005] Therefore, a split-type swing groove is provided to solve the above problems. Utility Model Content

[0006] The main purpose of this utility model is to solve the problems in the prior art where changing or replacing the swing groove requires manual operation, which is complicated, dangerous, and inefficient.

[0007] This utility model provides a split-type swing groove, the split-type swing groove comprising:

[0008] A blast furnace has a furnace platform fixedly installed on one side. A first installation slot and a second installation slot are provided on the furnace platform. One end of the first installation slot is located close to the blast furnace, and the other end of the first installation slot is connected to the second installation slot. A molten iron trough is provided in the first installation slot, and the end of the molten iron trough extends into the second installation slot. A tilting beam is provided at the bottom of the second installation slot. A swing groove bracket is detachably installed on the tilting beam. The swing groove shell is detachably installed on the swing groove bracket. A swing mechanism is fixedly installed on the side of the second installation slot away from the molten iron trough. The second installation slot also includes a swing rod. One end of the swing rod is fixedly connected to the swing mechanism, and the other end of the swing rod is rotatably connected to the swing groove bracket.

[0009] Optionally, the swing groove bracket includes a bracket body and a swing frame body, the swing frame body is fixedly installed on the bracket body, and a swing block is provided on the side of the swing frame body away from the bracket body.

[0010] Optionally, the end of the swing lever is provided with a swing groove to cooperate with the swing block, and the swing block and the swing groove are rotatably connected.

[0011] Optionally, a positioning block is provided at the bottom of the bracket body.

[0012] Optionally, the flip beam is provided with a positioning groove, which is set in conjunction with the positioning block on the swing groove bracket.

[0013] Optionally, a telescopic positioning mechanism is fixedly provided on both sides adjacent to the main body of the bracket and the main body of the swing frame. The telescopic positioning mechanism is an electric telescopic rod.

[0014] Optionally, the swing groove housing is provided with positioning holes in conjunction with the telescopic positioning mechanism.

[0015] Optionally, a molten iron ladle is also included, which is positioned below the swing trench shell.

[0016] This utility model provides a split swing trench, which separates the swing trench shell and refractory material part from the swing mechanism. The two parts are connected by a specific frame and mechanical locking mechanism. The original flip beam and connecting mechanism of the swing trench shell are eliminated, and a swing trench bracket is designed to support the swing trench, connect the swing arm, and drive the swing trench to achieve the flipping function through the flip beam. This allows personnel to change without having to connect and disconnect the swing mechanism at close range, and workers do not need to enter the danger zone, thereby reducing the danger to workers.
