Description
Technical field
The utility model is related to blast furnace ironmaking field devices, more particularly to a kind of online processing coal rifle gun breech valve can not act
Emergency set.
Background technology
Pulverized coal injection in blast furnace be the anchracite duff for being directly blown levigate into stove from blast-furnace tuyere or bituminous coal powder or this two
The mixed coal powder of person is play a part of to provide heat and reducing agent with substitute for coke, to reduce coke ratio, reduces production cost, it
It is an important technical revolution of modern blast furnace ironmaking, it is the key technology of blast furnace ironmaking survival and development.
Coal dust uses compressed air and nitrogen to convey after making powder by coal powder injection workshop, through coal spraying pipeline, distributor, then passes through coal
Rifle sprays into blast-furnace tuyere, under normal circumstances, the high 50~100kPa of coal injection system pressure ratio blast furnace wind pressure.In actual production process
In, it may appear that the abnormal conditions such as coal spraying pipeline blocks, coal powder injection workshop is died, when coal spraying pipeline blocks, coal rifle gun breech valve can not move
Work causes block clearing operation that can not complete, and when coal powder injection workshop is died, blast furnace wind pressure is more than coal injection system pressure, it will coal rifle is caused to return
Fiery accident occurs, and burns out the surrounding devices such as coal rifle, connection metal hose, as closed coal rifle gun breech valve and can avoid back-fire trouble
Occur, however, because of factors such as air port adverse circumstances, often will appear the phenomenon that coal rifle gun breech valve can not act.It passes at present
The processing method of system is：
1, coal rifle is replaced online, and there are certain security risks in the case of big blast furnace high wind pressure for this method, and in wire insertion
During coal rifle, coal rifle is easily stuck in rifle packet, leads to blast furnace staying.
2, directly pull out coal rifle, the phenomenon that this method is leaked out there are ball valve, and this air port can not coal powder injection, it is equal to influence blast furnace
Spray, influences gas fluid in blast furnace and is uniformly distributed.
Utility model content
Technical problem to be solved in the utility model be a kind of coal rifle gun breech valve is provided for the above-mentioned prior art can not
The online processing device of action realizes the abnormal conditions that online processing coal rifle gun breech valve can not act, coal rifle is effectively avoided to be tempered,
Burn out the accidents such as external connection metal hose and coal rifle.
The technical scheme in the invention for solving the above technical problem is：A kind of online processing coal rifle gun breech valve can not move
The device of work is set to online between coal gun breech portion and external connection metal hose, including quick coupling male connector 1, quick coupling
The short silk of female, ball valve, double end, the quick coupling male connector are connect with the ball valve by the short silk of double end, and the quick coupling is female
The other end of head and the ball valve is linked together by the short silk of another double end；Quick coupling male connector is soft for quickly connecting metal
Pipe, quick coupling male connector of the quick coupling female for quickly connecting coal gun breech portion.
In the case where there is coal powder injection pipeline chute blockage and the unusual service conditions such as coal powder injection workshop is died, when coal rifle gun breech valve can not act,
The quick coupling female of described device is connected in the quick coupling male connector in coal gun breech portion by line, by the quick coupling of described device
Male connector is connect with external metallization hose, and described device upper ball valve works instead of original coal rifle gun breech valve, realizes online processing coal
The abnormal conditions that rifle gun breech valve can not act effectively avoid coal rifle from being tempered, burn out the accidents such as external connection metal hose and coal rifle.
Compared with prior art, the utility model has the advantage of：
1, in the case where there is coal powder injection pipeline chute blockage and the unusual service conditions such as coal powder injection workshop is died, cause coal rifle gun breech valve that can not move
Make, online quickly processing avoids damping down, accident is made to minimize.
2, ensure the person, equipment safety.
3, the influence that the working of a furnace generates is minimized.
Description of the drawings
Fig. 1 is the structural schematic diagram for the device that online processing coal rifle gun breech valve can not act in the utility model embodiment.
Specific implementation mode
The utility model is described in further detail below in conjunction with attached drawing embodiment.
As shown in Figure 1, the emergency treatment device in the present embodiment is to be set to coal gun breech portion and external connection metal online
Between hose, the unusual service condition that can not be acted for handling coal rifle gun breech valve, including quick coupling male connector 1, quick coupling female
3, the short silk of ball valve 2, double end, quick coupling male connector 1 and ball valve 2 are connect by the short silk of double end 4, quick coupling female 3 and ball valve 2
The other end is linked together by the short silk of another double end 5.Quick coupling male connector 1 is for quickly connecting metal hose, quick coupling
Quick coupling male connector of the female 3 for quickly connecting coal gun breech portion.
The male connector of Quick connection part and corresponding female are fixed by locking ear.
When certain root coal rifle chute blockage or dies and need to handle, and when coal rifle gun breech valve can not act, disengage the metal of this coal rifle
Hose, while fetching water cooling to coal rifle, holding ball valve 2 is open state, and quick coupling female 5 is connected to the fast quick access in coal gun breech portion
In head male connector, ear is locked, then external metallization hose is connect by quick closedown ball valve 2 with quick coupling male connector 1, lock ear
Piece, coal powder injection can be restored by opening ball valve 2.
Above-mentioned apparatus can the abnormal conditions that can not act of online processing coal rifle gun breech valve, effectively avoid coal rifle from being tempered, burn
The accidents such as bad external connection metal hose and coal rifle.
In addition to the implementation, the utility model further includes having other embodiment, all to use equivalents or equivalent
The technical solution that alternative is formed, should all fall within the protection domain of the utility model claims.
