Description
Technical field:
[0001] The utility model relates to a collecting device, in particular to a mobile high-carbon ferrochrome pouring fume collecting device. Background technology:
[0002] High carbon ferrochrome is the most important raw material for producing stainless steel, that is, it is used as a gold agent for steelmaking. Currently, the raw chromite ore is directly added to the submerged arc furnace for smelting. After smelting, the furnace water is discharged from the submerged arc furnace into the molten iron ladle, and then the molten iron ladle is lifted to the slag removal station for slag removal. After slag removal, the molten iron is directly poured into the flow chute, and the molten iron flows along the flow chute to the casting and cooling platform below, where it is cooled and solidified. Later, it is shoveled away by a forklift and sent to the next crushing process. After crushing, it is packaged and sold. Currently, when the molten iron flows to the casting and cooling platform, a large amount of smoke will be generated during the cooling process. The smoke contains CO, H2, dust, etc. The smoke generated during the cooling process of the molten iron will pollute the factory environment and bring safety hazards to the operators.

[0005] Furthermore, a first track is fixed to one end of the casting and cooling platform away from the slag removal station, and at least two rotating shafts are rotatably arranged in parallel on one side of the dust collecting hood, and a first rail wheel matching the first track is respectively sleeved and fixed on each of the rotating shafts, and the first rail wheel is movably arranged on the first track; a driving motor is fixed to the dust collecting hood, and the output end of the driving motor is transmission-connected to one end of the rotating shaft; a second track parallel to the first track is hung and fixed on the roof above the other end of the casting and cooling platform, and at least two second rail wheels matching the second track are rotatably arranged on the other side of the dust collecting hood, and the second rail wheels are movably arranged on the second track.
[0006] Furthermore, a high-temperature refractory layer is provided on the inner wall of the dust collecting hood.
[0007] The advantages of the utility model are as follows: 1. The utility model has a simple structure and is easy to implement. By arranging a wall and a dust hood on the outside of the casting cooling platform, the smoke generated during the cooling of the molten iron can be effectively collected and sent out, avoiding smoke pollution of the factory environment, improving the working environment of the operators, and improving work safety; 2. After the cooling is completed, the dust hood is driven away, and then a forklift enters to shovel away the molten iron. The operation is convenient and simple. At the same time, the collected smoke is used as fuel for subsequent power generation, fully realizing the utilization of resources. Description of the drawings:
