Abstract
The utility model relates to a whirlwind-type copper-plate wind gap with three chambers, double inlets and double outlets, which is used for a hot wind inlet of an iron-making blast furnace. A water chamber of a front cavity is provided with independent water inlet passages and independent water discharge passages, and a back cavity is divided into two parts; a front section is provided with five whirlwind chambers which are mutually connected in series, and a back section is in a hollow cavity structure. The wind gas is made from a pressing and extending oxygen-free copper plate of which the copper content is more than 99.9 %. When the front cavity of the wind gap is burnt, and the water supply of the front cavity is stopped, cooling water is guaranteed to be supplied within all the 360 DEG range of the cross section of the back cavity of the wind gap and the back cavity can not be quickly burnt. Now, the production of the iron making blast furnace which is only cooled by the back cavity can be maintained.
Description
The utility model relates to a kind of three Room whirlwind-types copper coin air port that goes with each other all the time, and is specially adapted to the water cooled tuyere of iron-smelting blast furnace hot blast import.
At present, known two-chamber water cooled tuyere all is the cast copper goods, because the cast copper copper content is low, compactness is poor, and its thermal conductivity ratio fine copper plate has low about 38%.Reason because of the cast copper foundry engieering; its wall thickness can not be too thin; so when ante-chamber burns; when water inlet pipe is closed; the water-in and water-out passage that goes out of use will occupy 1/7th of air port section, and this part will lose the water-cooled protection, cause back cavity to burn rapidly; so work-ing life is short, will change once half a year approximately.
The purpose of this utility model provides a kind of three Room whirlwind-types copper coin air port that goes with each other all the time, it has overcome the short problem in work-ing life that above-mentioned two-chamber water cooled tuyere cavity configuration is caused, to be extended down to 12 months work-ing life, and guarantee cooling intensity to have increased cooling range.
Realize that scheme of the present utility model is: the air port is divided into forward and backward two cavitys.Ante-chamber is the shallow annular tray type structure, and the back cavity that joins with it is divided into two sections.The concentric circular cone jacket casing that the leading portion of back cavity is successively decreased by four conical butts and diameter is provided with similar spiral type dividing plate together outside between two layers the awl tube, form five spin chambers of serial connection mutually with this.The back segment of back cavity is a cavity structure.Whole air port all makes of the calendering anaerobic copperplate of copper content 〉=99.90%, and the argon arc welding is adopted in the connection place.Ante-chamber is by the cooling of water-in and water-out passage water flowing independently, because heat flow rate per unit area maximum herein so the flow velocity of design is also the fastest, reaches 17.2m/s.Intake by the back cavity water-in during back cavity cooling, the internal layer water entry of flowing through, be introduced into spiral septum foremost, promptly arrange at a high speed in the cavity of back cavity back segment along five spin chambers that are connected in series mutually that similar spiral shape dividing plate forms, the water speed of each spin chamber is followed successively by 15.20 backward in the past; 11.70; 10,10; 8.10m/s after the cooling of finishing the back cavity back segment, water is discharged from the back cavity water port.
The utility model three Room whirlwind-types copper coin air port that goes with each other all the time, it is the improvement of prior art and perfect, because the air port ante-chamber is provided with independently water-in and water-out passage water flowing cooling, so heat flow rate per unit area maximum, the worst zone of Working environment can be cooled off to greatest extent.Stop when ante-chamber supplies water when the air port ante-chamber burns, all guarantee the supply of water coolant in whole 360 ° of scopes of air port back cavity section, so unlikelyly cause burning rapidly of back cavity.In addition, the cooling-water flowing of air port back cavity leading portion outer wall is in the past to become to force helical flow backward, therefore makes the wall energy air port that works under hard conditions outside obtain the cooling of lower temperature water, and more near the front end cooling intensity more by force.
Below in conjunction with accompanying drawing the utility model is elaborated:
Fig. 1 is the three Room whirlwind-types copperplate air port front views that go with each other all the time;
Fig. 2 is I-0-I sectional view of Fig. 1;
Fig. 3 is II-0-II sectional view of Fig. 1.
As shown in Figure 1, 2, the air port is made up of ante-chamber 1 and back cavity 2.Ante-chamber 1 is the shallow annular tray type structure.The back cavity 2 that joins with it is divided into two sections; The concentric circular cone jacket casing that back cavity leading portion 3 is successively decreased by four conical butts and diameter is provided with similar spiral shape dividing plate 4 between two layers of awl tube together outside, forms five spin chambers 12 of serial connection mutually with this.The back segment 5 of back cavity is a cavity structure.Whole air port all makes of the calendering anaerobic copperplate of copper content 〉=99.90%, and the argon arc welding is adopted in the connection place.
When as shown in Figure 1, 2, the air port ante-chamber cools off; By ante-chamber water-in 6 water inlet, current flow 360 ° along its annular tray to ante-chamber 1 through water entry 7 independently, reach water exit 8, discharge from ante-chamber water outlet 9 again.
Shown in Fig. 1,3, during the cooling of air port back cavity; By 10 water inlets of back cavity water-in, current are through internal layer water entry 11, be introduced into similar spiral shape dividing plate 4 foremost, promptly arrange at a high speed in the cavity 5 of back cavity back segment, discharge by back cavity water outlet 13 again along five spin chambers that are connected in series mutually 12 that similar spiral shape dividing plate forms.
