Description

A kind of blast furnace taphole, which blows to burn, anti-blocking uses oxygen rifle
Technical field
The utility model relates to a kind of oxygen rifle, especially a kind of blast furnace taphole, which blows to burn, anti-blocking uses oxygen rifle.
Background technique
The heat budget balance of normal blast furnace process cupola well, heat are active plentifully.But because of reasons such as equipment feed operations When there is hearth chill or even gobbed up, no longer cold slag is discharged in wind-engaging, the channel for getting through iron mouth to air port to blast-furnace tuyere Iron becomes the key of the fast quick-recovery of blast furnace.
The method of cold slag iron is in conventional process and discharge furnace: using between oxygen burn through air port and air port, air port and slag iron Channel between mouthful frequently occurs when the slag iron in cupola well has begun condensation, is handled using conventional oxygen pipe and protrudes into Tie Kou It is blocked or even is blocked by slag iron in the process, cause to ventilate unsmooth, occur fire, air pressure crosses ambassador's Joint's falling off and hurts sb.'s feelings.Cause to locate It is long to manage the time, and oxygen pipe consumes the problems such as big, seriously polluted and security risk, and slow effect, not environmentally.
Utility model content
It is easy blocking in order to solve oxygen hose in treatment process in the prior art, the consumption of long processing period oxygen pipe is big, pollutes The problems such as serious and security risk is more.The utility model, which provides a kind of blast furnace taphole and blows, burns anti-blocking oxygen rifle, improves using the longevity Life, reduces environmental pollution, and reduces personal safety hidden danger.The concrete scheme of the utility model is as follows:
A kind of blast furnace taphole, which is blown, burns anti-blocking oxygen rifle, including outer tube, and the inner tube in outer tube, air inlet pipe one end is set to outer It is connected on pipe and with inner pipe end, air inlet pipe is at an acute angle with inner tube, and the inner tube other end is equipped with several escape pipes, and several escape pipes are set In at an acute angle on outer tube and with inner tube, fire resisting filler material is equipped between outer tube and inner tube.
Further, outer tube one end is additionally provided with drill rod thread head, and drill rod thread head is connect with chisel wall opening machine.
Further, the escape pipe of the oxygen rifle protrudes into iron mouth pore passage.
Further, angle is 45-60 ° between air inlet pipe and inner tube.
Further, several escape pipes are uniformly arranged on around the inner tube other end.
Further, several escape pipes angle between inner tube is 45-60 °.
Further, angle is 60 ° between air inlet pipe and inner tube.
Compared with prior art, the beneficial effects of the utility model are as follows:
(1) the utility model uses stainless steel tube as inner tube, and top seal side and -60 ° at 45 ° of axis are taken in front end The mode of angle aperture, duct blocks when avoiding use, and ventilation is fallen phenomena such as fiery.The casting of stainless steel tube outsourcing high temperature resistant iron runner Material, is put into iron mouth and seals, improve service life, reduce environmental pollution.
(2) the utility model digs wall opening machine in tail end welding drill rod thread head connection to be sent into iron mouth, can reduce the person Security risk.
(3) the utility model is put into iron mouth, and the oxygen and cokes in hearth of connection burn, and generates a large amount of heat melts Condensation slag iron in cupola well simultaneously forms high-temperature region in cupola well, and the thermal efficiency that the oxygen rifle of embedment generates is high, is conducive to get through Tie Kou Channel between air port, can fast quick-recovery State of Blast Furnace is cool, gobbed up, shorten the processing time, reduce security risk, save A large amount of human and material resources are saved, and economical, environmentally friendly, efficient.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, the technical solution in the present embodiment is carried out it is clear, complete Site preparation description, it is clear that described embodiment is only the example to a part of example of the utility model, rather than whole.Base In the embodiments of the present invention, those of ordinary skill in the art institute obtained under that premise of not paying creative labor There are other embodiments, fall within the protection scope of the utility model.
As shown in Figure 1, the blast furnace taphole of the present embodiment, which is blown, burns anti-blocking with oxygen rifle, including outer tube 3, in outer tube 3 in Pipe 5,2 one end of air inlet pipe are set on outer tube 3 and are connected to 5 end of inner tube, and air inlet pipe 2 and inner tube 5 are in 60 ° of angles, and inner tube 5 is another End is equipped with several escape pipes 6, and several escape pipes 6 are set on outer tube 3 and are in 60 ° of angles with inner tube, set between outer tube 3 and inner tube 5 There is fire resisting filler material 4.3 one end of outer tube is additionally provided with drill rod thread head 1, and drill rod thread head 1 is connect with chisel wall opening machine.Several outlets Pipe 6 is uniformly arranged on around 5 other end of inner tube.
In the present embodiment, outer tube 3 can be Φ 75mm steel pipe, and inner tube 2 can be stainless steel material, and air inlet pipe 2 can connect Lead to existing apparatus of oxygen supply.
Process of the utility model for one of working of a furnace of blast furnace to be handled is as follows:
Tapping machine is loaded into drilling rod before air-supply, the iron mouth opened and need to dredge first is bored with the drill bit of Φ 65mm, then use Φ instead It is exited at the drill bit of 75mm to iron lipstick point, the oxygen rifle of the present embodiment is attached on tapping machine, is headed into iron mouth pore passage at red dot And fix oxygen rifle, then the gap of gun body and iron mouth pore passage is filled with hydrous taphole loam, source of oxygen is connected in air inlet pipe, Oxygen flow is adjusted by control ball valve, the oxygen being blown into and cokes in hearth burn, generate in a large amount of heat melts cupola well Condensation slag iron and high-temperature region is formed in cupola well, be conducive to the channel got through between iron mouth and air port, then periodically move back oxygen rifle The slag iron mixture of fusing is discharged in tapping hole, since air inlet pipe is at a certain angle with inner tube with escape pipe, because without falling Fire will not block.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model Protection scope within.
