Abstract
The invention discloses a repairing device for a blast furnace cooling wall water pipe. The repairing device comprises a connecting pipe arranged on a cooling wall, a conical pipe is fixedly connected in a pipe orifice of the connecting pipe in an interference fit manner, a protecting pipe is fixedly connected on a cooling wall boss outside of the conical pipe, an outer sleeve is fixedly connected on a cooling wall shell outside the protecting pipe, pipe diameter of the outer sleeve is sequentially larger than that of the protecting pipe and that of the conical pipe, a straight pipe is fixedly connected at the outer side end of the conical pipe, a corrugated pipe is mounted outside the straight pipe in a sleeved manner, the inner side end of the corrugated pipe is hermetically connected with an inner annular retaining shoulder arranged on the inner peripheral wall of the inner side of the outer sleeve, two guide grooves are symmetrically formed in an axial pipe wall of the outer side end of the outer sleeve, an outer annular retaining shoulder is fixedly connected on the outer peripheral wall of the outer side end of the straight pipe, the outer side end of the corrugated pipe is hermetically connected with the outer annular retaining shoulder, and a guide rod extending into the corresponding guide groove is mounted at each of the upper end edge and the lower end edge of the outer annular retaining shoulder.
Description
Technical field
The present invention 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 object of the present invention is to provide a kind of prosthetic device 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 object of the present invention is achieved like this: 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 present invention 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 present invention is further detailed explanation.
Fig. 1 is that master of the present invention 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)
1. the prosthetic device of a water tube for cooling wall of blast furnace, be included in the pipe connecting that cooling stave is arranged, it is characterized in that: 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.
