Description
Technical field
The utility model design iron-smelting blast furnace hot-air system equipment relates in particular in a kind of blast-furnace tuyere and overlaps.
Background technology
Blast furnace is an airtight HTHP smelting vessel, and air-supply arrangement blasts hot blast through the air port cover that is installed on the furnace shell in stove, and the HTHP coal gas stream reducing iron ore that the coke burning generates is produced heating molten steel.The air port cover generally comprises big cover, middle cover and little cover, is the necessary equipment of blast-furnace smelting.
The air port cover forms blast furnace wind-engaging passage; Play the effect of near its firebrick lining of cooling, the HTHP coal gas in the Sealing furnace; Cover plays crucial effects within it in the air port; Extend in the stove part during use its inwall and outer wall all to receive the erosion of furnace high-temperature, cause its inner and outer wall early failure.The damage of overlapping in the air port has increased ironmaking cost on the one hand, can stop stove because of changing the air port on the other hand, has prolonged the ironmaking time;
The general water stream channel that injects of its inner chamber design of cover in traditional air port; The water flowing cooling; Water stream channel generally is the open circumferential Zigzag type that does not have the stationary flowpath direction, and cover in the whole air port is cooled off, and generally its paddle hole is arranged on the rear end of overlapping in the air port; Leave current unrestricted flow row leads, and can not produce heat-conducting effect efficiently.Because the front end that overlaps in the air port stretches into blast furnace, the suffered temperature of its front end is higher, so front end corrodes more easily and damages.
The utility model content
The technical problem that the utility model mainly solves provides and a kind ofly reduces production costs, long service life, power loss are little, overlap in the blast-furnace tuyere of good cooling results.
For solving the problems of the technologies described above, the utility model provides in a kind of blast-furnace tuyere and overlaps, and comprises flange and middle cover body; The cover body is the cone barrel sleeve of hollow in said, and said telescopic set inside has annular chamber, and cone barrel telescopic rear end is provided with prosopyle and posticum; Said prosopyle communicates with annular chamber with posticum, is provided with space bar in the said annular chamber, forms one and crosses aquaporin; Cross aquaporin passes to annular chamber earlier from the prosopyle front end; And at the front end of annular chamber around several weeks, prolong the front end and the reciprocal passage of rear end formation waviness of the inherent annular chamber of axial plane of annular chamber afterwards again, and pass to posticum.
The utility model improves to be had, and the reciprocal passage of said waviness is made up of a plurality of space bars that radially are arranged side by side along sleeve, and the aquaporin of crossing that said space bar surrounds communicates from beginning to end.
The utility model improves to be had, and said sleeve pipe is the fine copper forging.
The utility model improves to be had, and said flange is the steel flange.
The beneficial effect of the utility model is: link to each other with annular chamber through prosopyle, posticum; Space bar is arranged in the circular channel crosses aquaporin with being divided into one in the annular chamber, the water coolant that flows into from the prosopyle at first at the front end of annular chamber around, the front end that at first overlaps in the cooling air port; Improved the heat exchanger effectiveness of fore-end; Overlap in the whole cooling air port of cooling uniformly more afterwards, make the cooling of overlapping in the air port more reasonable, good cooling results; Guaranteed work-ing life of overlapping in the air port to have promoted distributing rationally of the energy.

Label declaration: 1-sleeve; The 11-prosopyle; The 12-posticum; The 2-annular chamber; The 21-space bar.
Embodiment
By the technology contents, the structural attitude that specify the utility model, realized purpose and effect, know clearly below in conjunction with embodiment and conjunction with figs. and give explanation.
With reference to accompanying drawing 1 to accompanying drawing 3, overlap in a kind of blast-furnace tuyere that the utility model provides shown in the accompanying drawing, comprise flange and middle cover body; The cover body is the cone barrel sleeve 1 of hollow in said; The set inside of said sleeve 1 has annular chamber 2, and the rear end of cone barrel sleeve 1 is provided with prosopyle 11 and posticum 12, and said prosopyle 11 communicates with annular chamber 2 with posticum 12; Be provided with space bar 21 in the said annular chamber 2; Form one and cross aquaporin, cross aquaporin from the prosopyle 11 pass to annular chamber 2 earlier front end, and at the front end of annular chamber 2 around several weeks; The front end and the rear end of prolonging the inherent annular chamber 2 of axial plane of annular chamber 2 afterwards again form the reciprocal passage of waviness, and pass to posticum 12.
Through crossing aquaporin; Make from the prosopyle 11 water coolants that flow to directly along the front end of axial flow to the annular chamber 2 of annular chamber 2; And the front end of annular chamber 2 around, its around number of turns the utility model do not limit, its can be according to the occasion of concrete use and the experience after using select; In the present embodiment two circles; This two circle is circulating for circumferentially, the reduction of maximum range overlap the temperature of front end in the air port, make the front end that overlaps in the air port in use be unlikely to the too high erosion damage that causes of temperature.
Afterwards cover in the air port is carried out integral body and lower the temperature, adopting the reciprocal passage of waviness is cooling-water duct, more uniformly cover in the air port is dispelled the heat; Good cooling results; Can effectively heat be discharged fast, avoid build-up of limescale, prolong the work-ing life of overlapping in the air port greatly.
With reference to accompanying drawing 1 to accompanying drawing 3, in the present embodiment, the reciprocal passage of said waviness is made up of a plurality of space bars 21 that radially are arranged side by side along sleeve 1 shown in the accompanying drawing, and the aquaporin of crossing that said space bar 21 surrounds communicates from beginning to end.
In the present embodiment; Said sleeve 1 is the fine copper forging, and is concrete certainly, and what present embodiment adopted is the manufacturing of split weldprocedure; The fine copper plate spinning parts of inlet front end adopt extraordinary welding with being connected of rear end fine copper cast parts; Compared with similar products, promptly guarantee quality, guaranteed suitable selling price again.
In the present embodiment, said flange is the steel flange.
The above is merely the embodiment of the utility model; Be not thus the restriction the utility model claim; Every equivalent structure transformation that utilizes the utility model specification sheets and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the utility model.
