Description
Technical field
The utility model relates to hot air duct technical field, particularly a kind of self-locking seal formula pipeline brick.
Background technology
Along with the strengthening of blast-furnace smelting, the raising of high wind-warm syndrome, high blast level, the problem that current domestic blast furnace ubiquity hot air duct structure is fallen brick, altered wind, appearance temperature is high, work-ing life is short.The wind-warm syndrome that hotblast stove can provide is at present 1000 ℃～1300 ℃, improving hot blast temperature is the important means that reduces coke ratio, improves coal ejection ratio, yet air supply duct rubescent limited the winding-up amount of hot blast temperature, oxygen enrichment percentage, coal dust, had a strong impact on normal production, and the severe attrition of heat energy and the decline of production output, the pernicious consequence that even causes pipeline to burn have been caused.
From the on-the-spot situation about understanding of some iron-smelting blast furnaces, pipeline is rubescent, fall brick position mainly concentrates on hot air duct top and circumferential weld periphery, and hot air duct is rubescent is mainly to alter wind-induced because of hot air duct circumferential weld and dilatation joint position.And then analysis conduit alters wind reason, be mainly that traditional hot air duct brick project organization and Working environment causes.Take blast-furnace hot-air pipeline traditional design structure and Working environment below analyzes the reason of easily altering wind as example:
1, blast-furnace hot-air pipeline brick structure is analyzed:
Blast-furnace hot-air pipeline is the main pipeline of heat air delivery, common hot air duct brick design, just avoided the Stability Analysis of Structures of pipeline radiation place, laterally top is connected with glossal canal, and although pipe tunnel is built by laying bricks or stones to have adopted and is connect stubble and build by laying bricks or stones or encircle and build, but in actual building process, brickwork joint is uncontrollable and increase along with piping displacement can produce circumferential weld longitudinally.
2, blast-furnace hot-air pipeline Working environment is analyzed:
Blast furnace is between on air, and the 1000 ℃～coal gas of 1300 ℃ and the mixed airflow of air (hereinafter to be referred as mixed airflow), with the speed of 55m/s left and right, the pressure of 0.4Mpa left and right, are transported to bustle pipe from hot air duct, then enter in blast furnace through air port.
Mixed airflow is responsible for through a plurality of bend pipes, taper(ed)pipe, control valve, blind plate etc. from hotblast stove to blast-furnace hot-air, add the reactive force in blast furnace, mixed airflow is now the pulse pneumatic within the scope of certain frequency, when pulse pneumatic is flowed through pipeline, can produce vibration.Blast furnace is during damping down, and in pipeline, temperature can sharply decline again, causes the masonry in pipeline to expand with heat and contract with cold, and produces certain displacement.
From the analysis of hot air duct project organization, no matter ring-like pipeline is builds or connects stubble by laying bricks or stones and build by laying bricks or stones, and circumferential weld all can change during operation to some extent, its on period will stand the washing away of vibration, exciting stream of pipeline, expanding with heat and contract with cold when air-supply and damping down, the quick breakage that this has all accelerated hot air duct masonry, causes hot air duct brick junction to alter wind, and to be also a lot of blast furnaces alter the rubescent basic reason of wind with regard to hot air duct building up some months for this.
Most of blast furnace man authors take perforate mud jacking, beat anchor ear, increase point of suppon, pipeline and miscellaneous equipment are tied together, or adopt and to spray water, to blow a cold wind over etc., these methods are both unreasonable, can not tackle the problem at its root, on the contrary, pipeline more easily destroys or endurance failure under irrational constraint.Since the Working environment of blast-furnace hot-air pipeline can not change easily, just need a kind of new design to solve hot air duct circumferential weld and alter this weakest position of wind.
Utility model content
The utility model provides a kind of Universal self-locking sealed pipe brick, to eliminate annulus and the radiation seam of pipeline brick junction in blast-furnace hot-air pipeline.
The technical solution of the utility model is achieved in that
A kind of Universal self-locking sealed pipe brick, comprise brick body, the first block that described brick body consists of one, the second block and contiguous block form, described the first block and described the second block are longitudinally misplaced and are connected to form brick body Z-shaped structure longitudinally by described contiguous block, and form the first pipeline brick groove in the longitudinal one end of described brick body, at described brick body the other end formation longitudinally second pipe brick groove, described the first pipeline brick groove can engage mutually with described second pipe brick groove; Described contiguous block two sides are respectively arranged with projection and the groove cooperatively interacting.
Wherein, preferably, the cross section of described the first block is inverted trapezoidal structure.
Wherein, preferably, the cross section of described the second block is inverted trapezoidal structure, and the side of the side of described the first block and described the second block homonymy is in same plane.
Wherein, preferably, the cross section of described projection and groove is isosceles trapezoid.
Wherein, preferably, the base of described isosceles trapezoid is connected by arc curve with side.
1. the utility model makes pipeline brick into the sealing of " Z " type and the sealing of emboss pit form, fundamentally solve the problem that traditional design easily produces annular straight joint and radiation seam when actual building by laying bricks or stones, can well resist the shearing force of hot, high-pressure pulsating air-flow and washing away of exciting stream, the displacement that the shrinkage of refractory materials heat expansion produces, and non-homogeneous expansion causes reserved dilatation joint to alter wind phenomenon, can also prevent from preferably producing when pulse pneumatic from flowing through pipeline the pipeline brick that vibration causes and become flexible with pipeline brick junction.
