Technical field

Oxygen technical field is sent the present invention relates to blast furnace ironmaking iron mouth, and specially a kind of Iron Works ironmaking iron mouth is with sending oxygen System.

Background technique

The blast furnace to come into operation is created into, because crude fuel is managed in the blast furnace of blow-on again after big or middle repair, or normal production Changing performance and certain reason such as larger fluctuation or misoperation occur causes the working of a furnace larger abnormal blast furnace occur, and it is different the working of a furnace occur Often, it often shows as into not wind, not out of slag, not out of iron, can generally be sayed without yield and quality and benefit, in such cases, Save one's life critical, how as early as possible by working of a furnace tune along being top priority.The production experience of decades expedites the emergence of out, implements iron confession oxygen Important means as the fast quick-recovery working of a furnace.The method of the abnormal working of a furnace of traditional processing is usually to spray iron mouth, it is intended to will be burnt in furnace The thermal energy conduction that carbon burning generates is guided to iron mouth, and by gas stream in the stove to iron mouth, sprays the condensation slag iron in furnace near iron mouth Mixture.Such processing, first is that serious to the damage in the channel Tie Kou.Second is that difficulty is larger, it is necessary to stop leeward and come, then pass through iron mouth Lead to oxygen combustion with air port oxygen lance, the cold slag iron between Jiang Tiekou and air port is burnt, and airflow channel is penetrated through.This process In, high temperature splashings constitute a threat to operating personnel and stokehold facility, noise, the dust polluting environment that when ejection generates.Splash Mostly important coke and ore use and its material of fusing, semi-molten in object or ironmaking production.In addition, damping down, multiple repeatedly Wind will lose the capacity of furnace and hold together the orderly distribution of material in random furnace, to aggravate working of a furnace deterioration, keep the recovery working of a furnace more difficult, The process for restoring the working of a furnace will be grown more slowly.What is more, quick-fried using explosive is placed from high temperature iron mouth quickly to handle the working of a furnace well It is broken, to get through channel between air port and iron mouth.Such way to equipment, to personnel, more serious to the threat of environment.Especially state Family is increasingly stringent to the management of industry and civil explosive material, and this processing mode is more and more undesirable, or even will be prohibited.

Summary of the invention

In view of the deficiencies of the prior art, the present invention provides a kind of Iron Works ironmaking iron mouths with oxygen system is sent, and solves Traditional processing method is dangerous, not environmentally, it is uneconomical, not efficiently, even illegal problem.

To achieve the above object, the invention provides the following technical scheme: a kind of Iron Works smelt iron iron mouth with sending oxygen system System, including oxygen rifle, escape pipe, protection pipe, snorkel, aerophore, oxygen hose and oxygen therapy machine, described send is sent to be fixedly connected in oxygen rifle There is escape pipe, the right end position for sending oxygen rifle is fixedly connected with pipette tips, and the left end for sending oxygen rifle, which is fixedly connected with, supplies gas Pipe and oxygen hose, for the snorkel away from sending one end of oxygen rifle to be fixedly connected with aerophore, the oxygen hose, which deviates from, send oxygen rifle One end is fixedly connected with oxygen therapy machine, is interconnected between the snorkel and oxygen hose by communicating pipe, is gone here and there on the communicating pipe It is connected with communicating valve, shut-off valve, third regulating valve, the second air gauge, oxygen instantaneous flow metering product are connected on the oxygen hose Instrument and the 4th regulating valve are calculated, is connected with shut-off valve, the first regulating valve, the first air gauge and the second regulating valve on the snorkel.

Preferably, the positioned inside for sending oxygen rifle has the first appendix, and the outer cover of first appendix is equipped with the Two appendixs, the protection pipe are sleeved on the outside of the second appendix, in the gap between the protection pipe and the second appendix Filled with phosphate refractory mud.

Preferably, the both ends of second appendix are tightly connected with the outer wall of the first appendix, second gas transmission Second pipe connector is fixedly connected on pipe, and the second appendix is interconnected by second pipe connector and snorkel, it is described Steel plate hanging ring is welded on the outer wall of second appendix.

Preferably, the left end of first appendix is provided with first pipe connector, and first appendix passes through first Pipe joint and oxygen hose are interconnected, and the right end of first appendix is fixedly connected with pipette tips, first appendix position One end inside the second appendix offers venthole, and the escape pipe is fixedly connected on the first appendix.

Preferably, the escape pipe is made of the first gas outlet and the second gas outlet, and second gas outlet is provided with two A, second gas outlet is symmetrically distributed on the first appendix about the first gas outlet center.

Preferably, the shut-off valve, the first regulating valve, the first air gauge and the second regulating valve are successively connected in by left-to-right On snorkel, second regulating valve is placed on the snorkel of communicating pipe right end.

Preferably, the shut-off valve, third regulating valve, the second air gauge, oxygen instantaneous flow measure integrating instrument and the 4th Regulating valve is successively connected on oxygen hose by left-to-right, and the 4th regulating valve is placed on the oxygen hose of communicating pipe right end.

The present invention provides a kind of Iron Works ironmaking iron mouths with oxygen system is sent, have it is following the utility model has the advantages that of the invention, Oxygen rifle, escape pipe, snorkel, aerophore, oxygen hose and oxygen therapy machine, the snorkel pipeline of compressed air control are sent by setting It is connected together by communicating pipe with communicating valve with the oxygen hose pipeline of Oxygen control, and send oxygen rifle with special by respective pipeline Connection, the effect of compressed air are scavenging conduit net, it is ensured that line clear is so that it is guaranteed that send oxygen safe.Another work of compressed air With being the dirt obstruction that ensures pipeline before sending oxygen not and can be driven in the wrong direction by force and to oxygen rifle cooling down, it is ensured that oxygen rifle is not burned, and And ensure without iron rust, without welding slag, without grit, without foreign matters such as greasy dirts in manage-style, thus conveying oxygen and compression easily and effectively Air, the present invention send the exquisite composition of oxygen rifle, and the three of the radially uniform distribution in oxygen rifle front end are arranged in compact-sized, good appearance The gas outlet of a reversed acanthoid structure ensures that it is not blocked by material in furnace, pointed cone pipette tips not only unity of form and spirit, increases aesthetic feeling, and Facilitate oxygen rifle to be accurately positioned as needed when installing, inserts refractory material, prevent high temperature from burning out；This is static passive protection, is led to Enter the compressed air in shell, gun body is cooled down and is purged；This is dynamic active defense, at the same still pipette tips it is anti-blocking two Layer defence line, send oxygen rifle rear end that firm steel plate hanging ring is arranged, and other than fixed function when playing handling, is also used as after sending oxygen rifle to install Anchor point, send three gas outlets of the radially uniform distribution in oxygen rifle front end in reversed acanthoid structure, alleviate and oxygen rifle is sent to install into iron Difficulty when mouth send oxygen rifle compact overall structure, shape exquisite, occupies little space, facilitates in iron mouth and place, solve traditional Processing method is dangerous, not environmentally, it is uneconomical, not efficiently, even illegal problem.
