Abstract
The utility model discloses a prosthetic devices of blast furnace stave water pipe, include the connecting pipe that sets up on the cooling wall, a lesson circular cone pipe to the interference fit rigid coupling in the mouth of pipe of connecting pipe, a lesson protecting tube to the rigid coupling on the cooling wall boss of circular cone outside of tubes, a lesson outer tube to the rigid coupling on the cooling wall casing outside the protecting tube, the pipe diameter of outer tube is greater than the pipe diameter of protecting tube and the pipe diameter of circular cone pipe in proper order, a straight tube to circular cone outside of tubes side rigid coupling, a lesson bellows to the outer suit of straight tube, the interior annular that sets up on the inboard internal perisporium of bellows medial extremity and outer tube is kept off and is takeed on sealing connection, outer tube outside rachis on to the pipe wall symmetry setting up two guide ways, the rigid coupling outer annular and is kept off the shoulder on the end periphery wall of the straight tube outside, bellows outside end keeps off shoulder sealing connection with outer annular, it extends to be equipped with one respectively in the outer annular fender shoulder -mounted lower extreme outer fringe guide bar in the guide way.
Description
Technical field
The utility model relates to a kind of blast furnace ironmaking field, particularly a kind of prosthetic device of water tube for cooling wall of blast furnace.
Background technology
Blast furnace cooling stave is the important cooling apparatus of blast furnace lining, be arranged on the positions such as the shaft of blast furnace, furnace bosh, bosh, cupola well, not only bear high temperature, also bear the wearing and tearing of furnace charge, the washing away of the erosion of slag and Gas Flow, the over-all propertieies such as good hot strength, heat shock resistance, anti-rapid heat cycle must be possessed.Cooling wall energy effectively prevents furnace shell to be heated and burns red, and blast furnace lining brick is ablated rear main by slag crust protection cooling stave itself, and maintains the safety in production of blast furnace.In the State of Blast Furnace labour later stage, the corrosion of cooling stave water pipe is thinning, cannot meet the normal hydraulic pressure water yield, the too high accident that booster will occur of the hydraulic pressure water yield, precipitation press operation, has a strong impact on the cooling system of blast furnace, also can burn out cooling stave in stove simultaneously, cause cooling wall breakage.The cooling stave water pipe at other positions can change process, but at cooling stave inner thinning with the pipe at external interface place after cannot change, this difficult problem annoyings smelter author always.
Summary of the invention
The purpose of this utility model is the prosthetic device providing a kind of water tube for cooling wall of blast furnace, the etching problem of pipe can be solved, pipe is planted by local, repair cooling stave inside and outside tube interface steel pipe, to meet the normal hydraulic pressure of cooling stave, the water yield, guarantee the ripple disable of blast furnace cooling system, meet blast furnace and normally produce.
The purpose of this utility model is achieved in that a kind of prosthetic device of water tube for cooling wall of blast furnace, be included in the pipe connecting that cooling stave is arranged, in the mouth of pipe of pipe connecting shrink-fit affixed a pitch circle Taper Pipe, affixed a joint protecting tube on cooling stave boss outside conical tube, affixed a joint outer tube on cooling stave housing outside protecting tube, the caliber of outer tube is greater than the caliber of protecting tube and the caliber of conical tube successively, conical tube outboard end affixed a straight tube, straight tube overcoat is filled with a joint corrugated tube, the interior annular shoulder block inside corrugated tube medial extremity and outer tube, internal perisporium arranged is tightly connected, the axial tube wall of outer tube outboard end is symmetrical arranged two guide paths, affixed outer ring shoulder block on straight tube outboard end periphery wall, corrugated tube outboard end and outer ring shoulder block are tightly connected, outer ring shoulder block upper and lower ends outer rim is equipped with a tail rod extended in described guide path respectively.
The utility model can solve the etching problem of pipe, pipe is planted by local, repair cooling stave inside and outside tube interface steel pipe, to meet the normal hydraulic pressure of cooling stave, the water yield, guarantee the ripple disable of blast furnace cooling system, corrugated tube prevents coal gas from leaking, ripple can cut down the effect of the shearing force to straight tube simultaneously, and tail rod positions straight tube, prevents straight tube from moving radially by external force, but but do not affect straight tube Axial Thermal bulging to become, meet blast furnace and normally produce.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is that master of the present utility model looks cross-sectional view.
Embodiment
A prosthetic device for water tube for cooling wall of blast furnace, as shown in Figure 1, be included on cooling stave 1 arrange pipe connecting 9, in the mouth of pipe of pipe connecting 9 shrink-fit affixed a pitch circle Taper Pipe 8.Affixed a joint protecting tube 7 on cooling stave boss outside conical tube 8, affixed a joint outer tube 12 on the cooling stave housing 3 outside protecting tube 7, the caliber of outer tube 12 is greater than the caliber of protecting tube 7 and the caliber of conical tube 8 successively.Conical tube 8 outboard end affixed a straight tube 14, straight tube 14 overcoat is filled with a joint corrugated tube 2, and the interior annular shoulder block inside corrugated tube 2 medial extremity and outer tube 12, internal perisporium arranged is tightly connected.The axial tube wall of outer tube 12 outboard end is symmetrical arranged two guide paths, affixed outer ring shoulder block 4 on straight tube outboard end periphery wall, corrugated tube 2 outboard end and outer ring shoulder block 4 are tightly connected, and outer ring shoulder block 4 upper and lower ends outer rim are equipped with respectively a tail rod 15 extended in described guide path.
Claims (1)
