Description

Hot bending bent pipe fan-shaped corrosion prevention operation device
Technical field
The utility model relates to the corrosion prevention operation device technical field of buried steel pipeline bend pipe in the petroleum and petrochemical industry, and simultaneously the utility model also is applicable to buried steel pipeline anticorrosion of other industry.
Background technique
The outer three-decker PE aseptic technic that anticorrosion a large amount of employing antiseptic properties are good, mechanical strength is high of domestic oil gas buried pipeline straight tube, pipeline office, Hua Long, Yadong, Hong Kong three big anticorrosion companies have set up pipeline straight tube three-decker PE anticorrosioning operation line in each elephant and the tube mill one after another at home, and state's interior conduit straight tube three-decker PE aseptic technic is in ripe vigorous period.And because the particularity of the geometric shape of bend pipe own, the outer anticorrosion main employing pitch glass cloth of bend pipe coats, heat-contraction sleeve coats, individual layer or dual-layer epoxy powder (or epoxy resin) spraying carrying out corrosion prevention operation, anticorrosion and unbecoming with the pipeline straight tube three-decker PE that develops rapidly, the at present domestic and international anticorrosion space state that also is in of bend pipe three-decker PE, and there is not a bend pipe three-decker PE anticorrosioning operation line, along with country strengthens the energy construction paces, oil and gas pipes is built fully under way, and the demand of bend pipe is rolled up, therefore, research and develop steel bend pipe three-decker PE anti-corrosion technology and the anticorrosion produce line suitable with steel pipe straight tube three-decker PE antiseptic property is necessary very much, this process engineering is removed the corrosion prevention operation of the buried steel pipeline bend pipe that is applicable to petroleum and petrochemical industry, also anticorrosion applicable to the buried steel pipeline bend pipe of other industry has the market space widely.
At present domestic except that an anticorrosion production line of bend pipe individual layer clinkery epoxy powder is had in Langfang pipeline office of parent company of group of CNPC, the bend pipe anticorrosion process of all the other manufacturers is mainly still based on the anticorrosion or manual baking heat-contraction sleeve of hand spray liquid epoxies anticorrosion process, aseptic technic falls behind, operation and production scale are less, speed of production is low, waste of raw materials is serious, anticorrosive quality low and be difficult to control.There are not bend pipe three-decker PE anticorrosioning operation line and similar products like abroad at present yet.All there is pipeline straight tube three-decker PE anticorrosioning operation line in country such as the U.S., Germany, its anticorrosion process and state's interior conduit straight tube three-decker PE anticorrosion process are similar, all be to adopt straight tube along production line transmission and rotation, the heating of intermediate frequency straight tube, first layer is with adopting static epoxy powder spraying (or other modes), the second layer adopts the hot extrusion binding tape to twine, and the 3rd layer is adopted hot extrusion polyethylene band to twine, form three-decker PE anticorrosion structure.
At this situation, the applying date is on February 11st, 2010, and application number is that the Chinese utility model patent document of 201010109340.x discloses a kind of hot bending bent pipe corrosion prevention operation system and operational method thereof, with reference to Fig. 1.
This hot bending bent pipe corrosion prevention operation system, comprise lift platform, discharging platform, frequency heating device 1, powder spraying device 2, wind 3 and cooling unit, also comprise rotary cantilever, rotary cantilever comprises the rotating beam 5 and the arc cantilever 6 that is arranged on the rotating beam 5 of wraparound rotating shaft 4 rotations, one end of rotating beam 5 is installed on the turning axle 4, the other end is supported on the arc track 7, hot bending bent pipe 8 is fixedly installed on the arc cantilever 6, frequency heating device 1, powder spraying device 2, wind 3 and cooling unit be along the movement locus setting of arc cantilever 6, and hot bending bent pipe 8 successively with frequency heating device 1, powder spraying device 2, wind 3 and cooling unit cooperate.The winding pipe 8 of instant heating heats by frequency heating device 1 earlier, carries out the epoxy powder spraying by powder spraying device 2 again, twines by wind 3 then, cools off by cooling unit at last.
Above-mentioned operational method and Operation System can be simplified three layers of anticorrosion drive line of PE of hot bending bent pipe, can improve the time of three layers of anticorrosion manufacturing operation of PE of hot bending bent pipe fast, improve the efficient of three layers of anticorrosion production of PE mechanization of hot bending bent pipe, realize the anticorrosion production of three layers of PE mechanization of hot bending bent pipe high efficiency, can satisfy the requirement of three layers of anticorrosion production of PE of extensive hot bending bent pipe, and can improve the antiseptic property of hot bending bent pipe, increase the working life of hot bending bent pipe.
But technique scheme has following shortcoming in actual use:
1, in order to improve work efficiency, usually adopt a plurality of elbows to be enclosed within and carry out corrosion prevention operation on the arc cantilever simultaneously, and the camber of each elbow has error, a plurality of elbows link together and will form very big difference, the circularity difference is very big, cause the arc cantilever that elbow is being delivered to frequency heating device, powder spraying device, when wind and cooling unit are handled, elbow can be run into arc track, and be unfavorable for that elbow just is positioned at frequency heating device, powder spraying device, the middle position of wind and cooling unit, at this moment just need manual intervention just can make elbow smoothly by and finish anticorrosion processing, cause work efficiency low, the up-to-standard rate of product is also had a strong impact on;
2, simultaneously, owing to a plurality of elbows are enclosed within on the arc cantilever, after elbow processes, at first need the fixing device of elbow and arc cantilever is taken apart, then the arc cantilever is screwed out elbow, just can finish processing the taking-up of elbow, this has also caused the low of work efficiency;
3, on the other hand, because the arc cantilever is by a rotating beam wraparound rotating shaft rotation, the arc cantilever is when moving in a circle, the arc cantilever is subjected to the component of centrifugal direction, be unfavorable for that more elbow advances by the movement locus of arc cantilever, elbow can be run into arc track, and be unfavorable for that elbow just is positioned at frequency heating device, powder spraying device, the middle position of wind and cooling unit, need manual intervention just can make elbow smoothly by and finish anticorrosion processing, but this has also caused the low of work efficiency more, can only process 4 elbows in common one day, and greatly influence the anticorrosion processing effect of elbow, influence the up-to-standard rate of product.
