Embodiment
See Fig. 1, iron bag spray dust-arrest device before a kind of Converter that the embodiment of the present invention provides, comprises swivel joint, the first flexible pipe 3, water pipe 4, valve 5, second flexible pipe 6, water distributing pipe 7 and shower nozzle 9;
Wherein, one end of swivel joint is connected with water source, and the other end of swivel joint is connected with one end of the first flexible pipe 3;
One end of water pipe 3 is connected with the other end of the first flexible pipe 4, and the other end of water pipe 3 is connected with one end of the second flexible pipe 6 by valve 5, and water source is caused height platform place, workshop by water pipe 3;
The other end of the second flexible pipe 6 is connected with one end of water distributing pipe 7, and the other end of water distributing pipe 7 is connected with shower nozzle 9, and water distributing pipe 7 is arranged in the middle and upper part of fire-screen door before Converter.
In embodiments of the present invention, this rotation rotary head is that six holes rotate rotary head, and porous rotates rotary head can according to water pipe direction, constantly adjustment water source water supply direction.In addition, in water source water supply direction rotary course, torque force can be produced, and the first flexible pipe 3 is for eliminating six hole swivel joint moments of torsion.Meanwhile, this dust-arrest device also comprises hand off valve 2, and hand off valve 2 is connected with the first flexible pipe 3 with swivel joint respectively, and hand off valve 2 cuts out water source for emergency situation, is in opened condition during normal use.Wherein, valve 5 to break cutting-off valve for gas, and pneumatic cut-off valve door adopts remote control, and action button is arranged at flushing and casting platform.
Wherein, the second flexible pipe 6 is U-shaped curved long soft-pipe, when stokehold fire-screen door opens closedown, be convenient to car traveling, in embodiments of the present invention, U-shaped curved long soft-pipe is a L=16M, the metallic hose of DN40, U-shaped curved long soft-pipe is for connecting 20.3m workshop water pipe and stokehold fire-screen door water lines.Meanwhile, resistant to elevated temperatures sleeve pipe is also wrapped up in the outside of U-shaped curved long soft-pipe, prevents stokehold high temperature from causing flexible pipe to damage.
Wherein, dust-arrest device also comprises adjustment flexible pipe 8, and adjustment flexible pipe 8 is connected with shower nozzle 9 with water distributing pipe 7 respectively, and adjust flexible pipe 8 and can adjust arbitrarily shower nozzle 9 direction within the specific limits, angle of guaranteeing to fetch water is reasonable.Wherein, shower nozzle 9 is spraying nozzle, can improve the injection flow velocity of current, atomizing spray, avoids that injection flow rate is bigger than normal affects the iron Bao Naicai life-span.Shower nozzle 9 is fixed on fire-screen door middle and upper part, stokehold, left side by steel pipe folder, and height, being about 0.5m place from iron handbag mouth top after converting iron, after shower nozzle 9 angular setting to the best, prevents nozzle angle in use procedure from departing from clamping the reserving of steel pipe.
In embodiments of the present invention, before this Converter, iron bag spray dust-arrest device using method is as follows: smelt 131B03913 heat, because smelting variety steel requirement, surplus half steel 10t, convert after iron completes, grate work commander overhead traveling crane falls auxiliary hook until iron bag medullary ray becomes 30 ° of angles with ground, start left side fire-screen door and iron bag centering, water source enters the first flexible pipe 3 from external water source access tube 1 by swivel joint, after six hole swivel joint moments of torsion eliminated by first flexible pipe 3, water source is caused the valve at 20.3m platform place, workshop, press flushing and casting platform open button, pneumatic cut-off valve door 2 is opened, this water source is under the effect of the second flexible pipe 6, water source can be caused in the fire-screen door of moveable stokehold, adjustment flexible pipe 8 is delivered to through water distributing pipe 7, adjustment spraying nozzle 9 angle is to optimum regime, water is sprayed onto iron bag by last spraying nozzle 9, the spray water xi spraying into iron bag inhibits the carbon in molten iron and the oxygen in air to react, fundamentally can solve iron bag to smolder problem.Spray water xi enters in iron bag and continues 16s, presses flushing and casting platform the Close button, and water spray water source cuts off, and overhead traveling crane falls auxiliary hook decoupling device, leaves and carries out operation next time.
Before not adopting spray dust-arrest device provided by the present invention, often there is roof smoke conditions in iron work, under same smelting process, after adopting this dust-arrest device, roof probability of smoldering is very low, adds up the smoke conditions of continuous 7 calendar months, wherein, front 5 calendar months do not adopt dust-arrest device of the present invention, and latter two calendar month have employed dust-arrest device provided by the invention, and statistical conditions of specifically smoldering are in table 1 and Fig. 2:
