Abstract
The utility model discloses a blast-furnace tuyere structure, which is formed by fireproof tiles and a thermal insulation layer and comprises tuyeres. The outer surface and the inner surface of each blast-furnace tuyere are both in regular polygon structures equal in edge numbers, the inner surface and the outer surface are parallel, the edge number of each regular polygon ranges from 12 to 24, and the tuyeres are arranged between the inner surfaces and the outer surfaces of lateral edges of the regular polygon structures. The blast-furnace tuyere structure adopts regular polygon structures and has the advantages of being easy to build. Used fireproof tiles are small in number of types, the blast-furnace tuyere structure is simple and regular in structure, easy to assemble and combine, easy to construct and fast in construction speed. The tiles of various types all can be formed in machine pressing mode, and are stable in quality and high in efficiency, thereby reducing production cost, facilitating construction at site and prolonging service life.
Description
Technical field:
The utility model relates to the improvement technology in high end furnace air port, is specifically related to a kind of blast-furnace tuyere structure.
Background technology:
At present, high end furnace mostly adopts cirque structure, and this structure is to be different from common planar to build by laying bricks or stones building by laying bricks or stones; It is big to build difficulty by laying bricks or stones; Because air port zone inside liner arc surface, the brick type of modular tile of press the arc surface design is quite complicated, to all strictnesses of requirement of brick type and brickwork joint coating.Local even need manual ramming, perhaps cast, vibrating forming, this conventional design method makes troubles to production, difficult quality control, yield rate is low, and difficulty is built at the scene by laying bricks or stones.Especially the setting in sidewall air port, the air port, side of annular further strengthen the difficulty of building by laying bricks or stones, occur the situation of doing over again easily, influence the whole construction progress.
The utility model content:
The utility model proposes a kind of blast-furnace tuyere structure to the deficiency of at present existing situation.
The technical scheme that the utility model adopted: a kind of blast-furnace tuyere structure; Constitute by refractory brick and thermal insulation layer; Comprise the air port, the outside surface of blast-furnace tuyere and internal surface are the regular polygon structure that the limit number equates, and inside and outside surface is parallel; The limit number of this regular polygon is 12～24, and the air port is between the surfaces externally and internally of each side of regular polygon.
The positive icosagon structure of blast-furnace tuyere.
The outer rim in each air port is set to circular groove structure.
The internal surface of said annular recesses is a cancave cambered surface.
The bottom of each side outside surface of regular polygon is provided with the support pin.
The top of each side is provided with the linking groove.
The useful positively effect of the utility model:
1, the utility model adopts the regular polygon structure, has the advantages that to build by laying bricks or stones easily.The brick type quantity of the refractory brick that uses is few, simple in structure and regular, pieces together combination easily, is beneficial to enforcement, and speed of application is fast.Each brick type is mechanical pressing all, steady quality, and efficient is high, reduces production costs thereby obtain, and build by laying bricks or stones at the scene of being convenient to, and improves the economical effectiveness in work-ing life.
2, because the inside and outside surface of each sidewall of regular polygon is the plane, be easier to, and the air port outer rim is provided with annular recesses easily, helps shutoff and sealing so the air port ratio is set in the plane.
3, the outside surface central lower of each side of regular polygon is provided with feet, need not calculate the position and the angle at right angle during enforcement again, realizes being uniformly distributed with the purpose of support easily.
Description of drawings:
Fig. 1 is the utility model plan structure synoptic diagram;
Fig. 2 is the local structure synoptic diagram of Fig. 1.
Label 1 is the blast-furnace tuyere structure among the figure, and 2 is the air port, and 3 is feet, and 4 for being connected groove, and 5 is annular recesses, and 6 is the planar side of regular polygon.
Embodiment:
Embodiment one: referring to Fig. 1 and Fig. 2, and a kind of blast-furnace tuyere structure, its outside surface and internal surface are the positive icosagon structure that the limit number equates, and inside and outside surface is parallel, and air port 2 is between the surfaces externally and internally of each side 6 of regular polygon.The outer rim in each air port is set to annular recesses 4 structures.
The internal surface of said annular recesses 5 is a cancave cambered surface.The bottom of each side outside surface is provided with supports pin 3.The top of each side is provided with and is connected groove 4.
Embodiment two: accompanying drawing is not drawn, and content and embodiment one are basic identical, and something in common does not repeat, and different is: adopt positive ten hexagonal small blast furnace tuyere structures.
Embodiment three: accompanying drawing is not drawn, and content and embodiment one are basic identical, and something in common does not repeat, and different is: adopt positive 20 tetragonal miniaturized blast-furnace tuyere structures.
