Embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated.
As shown in Figure 1, railway supplyline desulphurization system of the present utility model, comprises railway supplyline 1, hot-metal ladle and carriage 2, KR stirrer 3, and described hot-metal ladle and carriage 2 is provided with iron ladle 5, described hot-metal ladle and carriage 2 runs on railway supplyline 1, and described KR stirrer 3 is arranged on railway supplyline 1.
The utility model adopts the desulfurization of KR stirring desulphurization method, when carrying out desulfurization, first hot-metal ladle and carriage is under the traction of 2 its headstocks, moves to below KR stirrer 3 along railway supplyline 1, when iron ladle 5 is just to KR stirrer 3, transfer the stirring-head of KR stirrer 3, add sweetening agent and carry out stirring desulphurization, stir after terminating, stirring-head raises up, and then hot-metal ladle and carriage 2 traction is left, so just can realize sulfur removal technology very easily.
For ease of dragging for slag before and after desulfurization, as optimal way, be provided with dragveyer 4 at KR stirrer 3 along front and back two side of railway supplyline 1.Specifically, front and back dragveyer 4 can be arranged at the distance of the about vehicle frame of distance KR stirrer 3, the dragveyer 4 being arranged at KR stirrer 3 upstream drags for the bits before desulfurization, and the dragveyer 4 being arranged at KR stirrer 3 downstream drags for the bits after desulfurization.
In above-mentioned whipping process, vehicle frame there will be to rock and brings security risk, for stablizing car body in stirring, as optimal way, described hot-metal ladle and carriage 2 vehicle frame both sides have U-shaped structure 7, railway supplyline 1 is provided with the drift 8 with the corresponding adaptation of described U-shaped structure 7 below described KR stirrer 3, described drift 8 is connected with the hydro-cylinder driving its motion.
After hot-metal ladle and carriage 2 moves to mixing position, drift 8, under the driving of hydro-cylinder, bottom the U-shaped structure 7 of wedging vehicle frame both sides, is stablized car body, and then is stirred, and can prevent from shaking in its whipping process.After stirring completes, drift 8 exits, and hot-metal ladle and carriage 2 can normally run.
Need dust-collecting fume hood 6 is set in sweetening process and carries out dedusting, but the locomotive engine height of hot-metal ladle and carriage is higher, locomotive engine can be caused after dust-collecting fume hood 6 is set below KR stirrer 3 to pass through, for addressing this problem, as optimal way, dust-collecting fume hood 6 is provided with below KR stirrer 3, described dust-collecting fume hood 6 is divided into A section petticoat pipe 61 from top to down, B section petticoat pipe 62, C section petticoat pipe 63, described A section petticoat pipe 61 is fixed on below KR stirrer 3, described B section petticoat pipe 62 to be set on A section petticoat pipe 61 and can relatively sliding, C section petticoat pipe 63 to be set on B section petticoat pipe 61 and can relatively sliding, described B section petticoat pipe 61 and C section petticoat pipe 63 are all connected with the hydro-cylinder for driving it to move up and down.
When hot-metal ladle and carriage 2 locomotive engine passes through, B section petticoat pipe 62 and C section petticoat pipe 63 are upwards packed up under Driven by Hydraulic Cylinder, and locomotive engine passes through smoothly, and when stirring, B section petticoat pipe 62 and C section petticoat pipe 63 are transferred, and cover iron ladle 5, play its dustproof function.
Below embodiment of the present utility model:
First, on the railway supplyline 1 between blast furnace to steelworks, selected desulfurization equipment building site,
At desulfurization station construction period, this railway supplyline is closed.Directly over railway line, determine the position of KR stirrer 3, determine position and other processing set-up of dragveyer 4 with the position of KR stirrer 3; KR stirrer 3 and sweetening agent storehouse be arranged in high across, built on stiltsly to arrange, dragveyer 4 platform and operation room be arranged in low across, electric panel room is arranged in below operation room.Drag for slag take off rake, stirring-head and handling desulfurization slag basin, low across establishing one 16 tons drivings to change.Dust-collecting fume hood 6 be located at high across KR stirrer 3 platform below, dedust air duct passes through and stirs platform and receive fly-ash separator.In sweetening process, prevent rocking of iron ladle, design an oil hydraulically powered drift device and iron ladle is stablized.
Hot-metal ladle and carriage 2 drags for slag position needing the iron ladle 5 of desulfurization to be first positioned at upstream, and drag for slag before carrying out desulfurization, dragveyer 4 picks up the bits in iron ladle 5 and is put in slag basin.After having dragged for slag, hot-metal ladle and carriage 2 is drawn to below KR stirrer 3, and bottom the U-shaped structure 7 of employing Driven by Hydraulic Cylinder drift 8 wedging vehicle frame both sides, put down dust excluding hood 6, decline stirring-head stirs, and adds sweetening agent by processing requirement simultaneously.After stirring, hot-metal ladle and carriage 2 is drawn to downstream and drags for slag position and carry out dragging for desulfurization slag, adds insulating covering agent, then hot-metal ladle and carriage 2 is drawn to steelworks after having dragged for.
