Embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
As Fig. 1, Fig. 2, shown in Fig. 3, described a kind of converter oxygen gun inserts gun barrel, comprise: be installed on the slotting gun barrel body on fire door flue 1, described slotting gun barrel body is formed by interior pipe 2 and outer tube 3 chuck, the first jet pipe group that some circles are formed by some first jet pipes 4 is from up to down evenly arranged with in outer tube 3 outside of slotting gun barrel body, the spout often enclosing the first jet pipe 4 in the first jet pipe group all inwardly stretches into interior pipe 2 from the outer tube 3 of slotting gun barrel body, some second jet pipes 5 are evenly distributed with along inserting gun barrel body circumference in the interlayer that pipe 2 and outer tube 3 are formed in slotting gun barrel body, the spout of all second jet pipes 5 stretches out from the bottom of slotting gun barrel body downwards, all first jet pipes 4 and the second jet pipe 5 respectively by connecting pipeline simultaneously with water route 6, steam pockets 7 and nitrogen storage tank 8 are connected, in the present embodiment, the first jet pipe group and lower first jet pipe group is from up to down arranged with in outer tube 3 outside of slotting gun barrel body, all first jet pipes 4 in upper first jet pipe group are connected with the upper endless tube 9 be enclosed within outer tube simultaneously, all first jet pipes 4 in lower first jet pipe group are connected with the lower endless tube 10 be enclosed within outer tube simultaneously, upper endless tube 9 is connected by intermediate connection tube 11 with lower endless tube 10, all second jet pipes 5 are connected with intermediate connection tube 11 simultaneously, upper endless tube by the first valve is installed 12 the first connecting branch 13 be connected with nitrogen storage tank, lower endless tube 10 is connected with carbonated drink house steward 14, carbonated drink house steward 14 is connected with steam pockets 7 by the second connecting branch 16 being provided with the second valve 15, carbonated drink house steward 14 is connected with water route 6 by the 3rd connecting branch 18 being provided with the 3rd valve 17, achieve all first jet pipes 4 like this, all second jet pipes 5 are communicated with water route 6 simultaneously, steam pockets 7 and nitrogen storage tank 8, this syndeton is simple, installation and maintenance are convenient,
Principle of work reason of the present invention: insert gun barrel when oxygen rifle and rest on oxygen rifle after blowing station, be displaced downwardly to the process of oxygen rifle opening and closing oxygen point station at oxygen rifle from oxygen rifle station to be blown, now due to the harsh product of new stove, water in steam pockets 7 is not also by thermogenesis water vapor, therefore the second valve 15 and the 3rd valve 17 is needed to close, the water in steam pockets 7 and water route 6 is avoided to enter converter by inserting gun barrel, affect converter normally to produce, open the first valve 12 simultaneously, the nitrogen in nitrogen storage tank 8 is made to spray into slotting gun barrel along the first jet pipe 4, and spray bottom slotting gun barrel from the second jet pipe 5 simultaneously, the air-casing be made up of nitrogen is defined like this at slotting gun barrel inwall and bottom, thus avoid the impurity in flue gas and slag to be displaced downwardly to from oxygen rifle station to be blown the process of oxygen rifle opening and closing oxygen point station at oxygen rifle sticking to slotting gun barrel inwall and bottom, along with oxygen rifle continue move down, water now in steam pockets 7 has been heated and has created water vapor, be displaced downwardly to the process of oxygen rifle blowing station at oxygen rifle from oxygen rifle opening and closing oxygen point station, close the first valve 12, and open the second valve 15, the water vapor in steam pockets 7 is made to spray into slotting gun barrel from the first jet pipe 4, spray to bottom slotting gun barrel from the second jet pipe 5 simultaneously, make the air-casing that the air-casing that in steam pockets 7, water vapor is formed replaces nitrogen to be formed, so not only save nitrogen, save enterprise's production and application cost, also avoid the impurity in flue gas and slag to be displaced downwardly to from oxygen rifle opening and closing oxygen point station the process of oxygen rifle blowing station at oxygen rifle all the time and stick to slotting gun barrel inwall and bottom, when oxygen rifle be displaced downwardly to oxygen rifle blowing station normally blow time, open the first valve 12 again, the nitrogen in nitrogen storage tank 8 is made to spray into slotting gun barrel from the first jet pipe 4 together with the water vapor in steam pockets 7, spray to bottom slotting gun barrel from the second jet pipe 5 simultaneously, thus define the little air-casing of the atomizing particle that is made up of water vapor and nitrogen at slotting gun barrel inwall and bottom, the flow velocity of this air-casing is faster, can not only avoid the impurity in flue gas and slag in converting process, stick to slotting gun barrel inwall and bottom better, also can cool slotting gun barrel inwall and bottom, under avoiding slotting gun barrel and oxygen rifle to be in the bad working environments of high temperature all the time, extend the work-ing life of slotting gun barrel and oxygen rifle further, after finishing blowing, when oxygen rifle is promoted to oxygen rifle in time blowing station from oxygen rifle blowing station, close the first valve 12 and the second valve 15 and open the 3rd valve 17 simultaneously, the water in water route 6 is made to spray into slotting gun barrel from the first jet pipe 4, and spray at the bottom of slotting gun barrel from the second jet pipe 5, make water carry out cooling to the oxygen rifle in slotting gun barrel inwall and bottom and slotting gun barrel to remove slag, avoid slag and flue gas impurities adhere at slotting gun barrel inwall and bottom and oxygen rifle outer wall further, thus extend the work-ing life of slotting gun barrel and oxygen rifle, the present invention has effectively can avoid the generation of slagging scorification phenomenon at slotting gun barrel inwall and bottom of slag and flue gas impurities adhere, not only extends the work-ing life of slotting gun barrel and oxygen rifle, reduces enterprise's production and application cost, also improve production security.
