Description
Technical field
The invention belongs to non-ferrous metal smelting technology more particularly to a kind of smelting furnace side-blown spray gun jack automatic hole sealings
Device.
Background technique
Side-blowing bath melting technique passes through development in more than 20 years, and technology maturation is reliable, efficient low-consume, adapts to raw material
Property it is strong, environmental protection, economic benefit are prominent, already become a kind of smelting process of emerging maturation.
Side-blowing bath smelting process is widely used in the metal smelts such as lead, copper, reviver and clinker field, is by being mounted on
The spray gun of furnace body side wall sprays into oxygen-enriched air, reducing agent and fuel etc. into molten bath, material in molten bath is heated, is melted,
Agitation, blowing are to accelerate heat transfer, mass transfer and chemical reaction process in molten bath.
Under normal circumstances, spray gun is produced by the spray gun jack on furnace body side wall brick by manually protruding into spray gun in molten bath
Spray gun, which frequently operates, in the process easily causes spray gun jack to damage and constantly expand, and leads to that fire, acceleration of leaking out are returned and (altered) at jack
Spray gun brick, furnace body side wall scaling loss, closure is poor, has lost a large amount of thermal energy, shortens the service life of smelting furnace.
Summary of the invention
The invention aims to provide a kind of smelting furnace side-blown spray gun jack automatic hole sealing device, the prior art is solved
Return and (alter) at spray gun jack fire, leaking out accelerates spray gun brick, furnace body side wall scaling loss, closure is poor, has lost asking for a large amount of thermal energy
Topic.
The object of the present invention is achieved like this: automatic hole sealing device includes: that fixed plate, limit plate, spray gun enter hole, fixation
Plate hole, movable plate, guide groove plate, spray gun card slot and moving plate aperture；
Fixed plate is mounted at spray gun jack；There is spray gun to enter hole in fixed plate, it is limited in the one side edge connection that spray gun enters hole
Position plate；There is fixed plate hole in fixed plate, has fixing bolt on fixed plate hole；Movable plate fits in the outer end face of fixed plate, living
The moving plate aperture of movable plate is mounted on fixing bolt, and movable plate can be rotated by axis of fixing bolt；There is spray gun card on movable plate
Slot is connected with guide groove plate in the bottom of spray gun card slot, and the spray gun card slot of movable plate and the spray gun of fixed plate enter hole and be mutually closed.
The limit plate, is connected in fixed plate vertically, and tilts outward.
The guide groove plate, is connected on movable plate vertically, and tilts to the opposite direction of limit plate, relative to limit
Plate is an open type structure；The moving plate aperture is located on the eccentric position of movable plate, using moving plate aperture as axle center, movable plate
Guide groove plate turn to the limit Board position in fixed plate naturally, movable plate lives spray gun clean-out cover.
Beneficial effect, as the above scheme is adopted, movable plate fit in the outer end face of fixed plate, in the fixation of fixed plate
There is fixing bolt on plate hole, the moving plate aperture of movable plate is mounted on fixing bolt, and moving plate aperture is located at the eccentric position of movable plate
It sets, movable plate can make eccentric rotary by axis of fixing bolt, and the guide groove plate of movable plate turns to the limit in fixed plate naturally
Board position, movable plate live spray gun clean-out cover.
When spray gun is inserted into smelting furnace, push lance head reaches the open type structure bit of guide groove plate and limit plate
It sets, spray gun continues to move ahead along open type structure, guide groove plate is pushed, in the common of movable guide groove plate and fixed limit plate
Under effect, movable plate makees eccentric rotary by axis of fixing bolt, and the spray gun that guide groove plate is covered enters hole and is exposed；Spray gun into
After entering smelting furnace, guide groove plate and spray gun enter hole and just block spray gun；
After spray gun is extracted out from inside to outside from smelting furnace, due to the moving plate aperture on movable plate be eccentric position, movable plate naturally with
Fixing bolt is that axis makees eccentric rotary, and the guide groove plate of movable plate turns to the limit Board position in fixed plate naturally, and movable plate will
Spray gun clean-out cover in fixed plate is lived, and ensure that the heat of smelting furnace does not leak, and solves to return at the spray gun jack of the prior art
The problem of (altering) fire, leaking out accelerates spray gun brick, furnace body side wall scaling loss, and closure is poor, has lost a large amount of thermal energy, has reached this hair
Bright purpose.
Advantage: the present invention, which effectively mitigates even to be eliminated in production process, washes away erosion to spray gun brick and side wall, extends side wall
The service life of refractory brick and metallurgical furnace.
1, spray gun jack is closed, and is not leaked out, and does not return fire, is reduced spray gun brick high temperature scaling loss, is corroded.
2, the service life of spray gun and spray gun brick is effectively extended, the replacement number of spray gun and spray gun brick is reduced, is dropped
Low production cost, ensure that the stabilization of production.
3, it is flexible to operation, it is easy-maintaining.
