Description
Technical field
The utility model is related to coal injection device for blast furnace device, specially a kind of blast-furnace tuyere Anti-air-leakage spray gun device.
Background technology
In prior art, mostly use greatly blast furnace ceramics spray gun, bitubular spray gun etc. carry out coal powder injection, blast furnace ceramics spray gun it is interior
Surface applies wear-resistant ceramic, and compressed air cooling is blown between the inside and outside sleeve of bitubular spray gun, and material cost is high, manufacture craft is multiple
It is miscellaneous, compressed air dosage is big, operating cost is high, service life is short, generally 30-60 days；And when plug spray gun, blast-furnace hot-air
It easily leaks, influences the continuous uniform coal injection of blast furnace.
Invention content
The utility model in order to solve existing spray gun there are blast-furnace tuyere easy to wear, that coal dust sprays into uneven and while drawing guns is easy
The problem of tempering, provides a kind of blast-furnace tuyere Anti-air-leakage spray gun device.
The utility model adopts the following technical scheme that realization：A kind of blast-furnace tuyere Anti-air-leakage spray gun device, including spray
Rifle and ball valve；Ball valve includes box valve body, and the left side of box valve body is provided with the tubulose chuck communicated therewith, box valve
The right side of body, which is provided with, to be communicated therewith and the steel pipe coaxial with tubulose chuck, and the right part side wall of steel pipe is socketed with and blast furnace connects
The flange connect is installed with casing in tubulose chuck, and outside of sleeve wall is provided with limiting slot, and tubulose chuck sidewall is screwed with matches with limiting slot
The stop screw of conjunction, casing left part side wall are provided with handle and fastening bolt, and two upper and lower directionss are fixed in box valve body
The square steel being obliquely installed, be provided between two square steel along both the sphere that rolls and coordinate with tubulose chuck right end nozzle；Spray
Rifle is tubular structure, and spray gun sequentially passes through casing, box valve body, steel pipe and is connected to blast furnace, and the right part madial wall of spray gun is
Left side internal diameter is less than the cone structure of right side internal diameter, and the right part of spray gun is obliquely installed, and spray gun lateral wall is provided with and fastens
The bolt hole of bolt cooperation.
When carrying out coal powder injection operation, spray gun is sequentially passed through into casing, box valve body, steel pipe and enters blast furnace, across box valve
Sphere is jacked up obliquely when body, fastening bolt is then tightened and fixes spray gun, gun slot is adjusted by rotational handle at this time
Direction, and then coal powder injection direction is adjusted, it ensure that the uniform penetrating of coal dust；When needing to extract spray gun, effect of the sphere in gravity
It is lower to be rolled obliquely along square steel to being blocked at tubulose chuck right end nozzle, so that the hot wind in blast furnace is not leaked, overcomes existing
The problem of uneven and while drawing guns being sprayed into the presence of spray gun blast-furnace tuyere easy to wear, coal dust and is easily tempered.
The adjacent side of two square steel is the convex structure coordinated with sphere.
The structure design further improves the stability that sphere rolls on square steel.
Tubulose chuck right end nozzle is the convex structure coordinated with sphere.
The structure design further improves the degree of agreement of sphere and tubulose chuck nozzle, and sealing performance obtains further
Promotion.
It is reliable that the structure design of the utility model is reasonable, and the structure design of spray gun so that coal dust firing is more abundant, coal powder injection side
To adjustable easily-controllable, the generation for wearing blast-furnace tuyere phenomenon is prevented, service life is increased dramatically, and the structure of ball valve
Design while fixed spray gun, can plug spray gun with pressure, when ensure that spray gun plug and adjustment operation in blast furnace hot wind without letting out
Leakage, and then ensure that the continuous uniform coal injection in blast furnace, have the advantages that simple in structure, easy to process and at low cost.
