Abstract
The utility model relates to a heater is peeled off to outer anticorrosive coating of wheel style. Mainly solved exist among the prior art with the roast outer anticorrosive coating of the 3PE the problem uneven and partial carbonization that results in being heated of peeling off of liquefied gas. Its characterized in that: main intake pipe (9) equidirectional 2 group's adjustable supporting legss (5) that set up perpendicularly, every adjustable supporting legs (5) other end and pipe wall contact department installation universal wheel (6), main intake pipe (9) one side is provided with three air intake branch (10), and adjustable shower nozzle support (4) are connected respectively in three air intake branch (10), adjustable shower nozzle support (4) are connected in main intake pipe (9), every air intake branch (10) perpendicular equidistance is provided with a plurality of flame shower nozzle (11), three (10) one ends of air intake branch merge connects house steward total union coupling air inlet hose (8). This heater is peeled off to outer anticorrosive coating of wheel style guarantees that the heater is peeled off to outer anticorrosive coating of wheel style heating is even.
Description
Technical field
The utility model relates to a kind of heater in oil extraction in oil field technical field, is a kind of rotary-type external anticorrosive coating peeling heater specifically.
Background technology
The steel pipe that long distance pipeline welders training uses comes from line construction the short circuit that cannot continue to use mostly.Because short circuit is the production tube with external anti-corrosion layer, must by 3PE external anticorrosive coating peeling before using.Current stripping 3PE external anti-corrosion layer technical method is: first roasting heating in production tube outside with liquefied gas, when 3PE external anti-corrosion layer is in soft state, then peels off piecemeal with flat chisel.For the problem that 3PE layer is separated with steel pipe, there is many drawbacks in conventional method: one is comparatively serious by external environment influence, when wind speed is excessive, flame heat regulating can be caused to run off, and then affect operating efficiency.Two is there is healthy hidden danger, and because the problems such as imperfect combustion very easily easily produce person pernicious gas in flame combustion and anticorrosive coat softening process, and these pernicious gases are very easily by operator's suction body.Three is partial carbonizations, when flame combustion is unstable, very easily causes local overdo and cause external anti-corrosion layer carbonization.
Summary of the invention
Technical problem to be solved in the utility model overcomes the existing liquefied gas existed in background technology to bake the problem peeled off external anti-corrosion layer and cause partial carbonization, and a kind of rotary-type external anticorrosive coating peeling heater is provided, this rotary-type external anticorrosive coating peeling heater, ensure rotary-type external anticorrosive coating peeling heater homogeneous heating, heating overall process does not contact with external anti-corrosion layer, has stopped partial carbonization.
The invention for solving the technical problem reaches by following technical scheme: this rotary-type external anticorrosive coating peeling heater, comprise steel pipe, steel pipe outer cladding external anti-corrosion layer, the horizontal axis of described steel pipe is provided with main air inlet pipe, described main air inlet pipe is equidirectional vertically arranges 2 groups of adjustable support pin, and universal wheel is installed in each adjustable support pin other end and tube wall contact position; Described main air inlet pipe side is provided with three air intake branches, and three air intake branches connect nozzle adjustable support respectively, and described nozzle adjustable support is connected in main air inlet pipe; Each air intake branch is vertically equidistantly provided with some flame spray heads, and the merging of described three air intake branch one terminations is connected to house steward, and house steward connects air induction hose.
The utility model can have following beneficial effect compared with above-mentioned background technology: this rotary-type external anticorrosive coating peeling heater, owing to adopting said structure, adopts rotary-type external anticorrosive coating peeling heater originally will first to heat 1 procedure integrating heating, peeling simultaneously at 2 procedures of peeling.And rotary-type external anticorrosive coating peeling heater homogeneous heating, heating overall process does not contact with external anti-corrosion layer, has fundamentally stopped partial carbonization.When extraneous wind speed is larger, pipe one end can be done temporary plugging to reduce thermal loss.Be very effective in the application, compared with traditional heating mode, have reduce labour intensity, improve peeling efficiency, the advantage such as the scope of application is large, safety and environmental protection.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is side views of the present utility model.
1-steel pipe in figure, 2-external anti-corrosion layer, 3-shutoff, 4-nozzle adjustable support, 5-adjustable support pin, 6-universal wheel, 7-handwheel, 8-air induction hose, the main air inlet pipe of 9-, 10-air intake branch, 11-flame spray head.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in accompanying drawing 1, Fig. 2, this rotary-type external anticorrosive coating peeling heater, comprise steel pipe 1, steel pipe 1 outer cladding external anti-corrosion layer 2, the horizontal axis of described steel pipe 1 is provided with main air inlet pipe 9, described main air inlet pipe 9 is equidirectional vertically arranges 2 groups of adjustable support pin 5, and universal wheel 6 is installed in each adjustable support pin 5 other end and tube wall contact position; Described main air inlet pipe 9 side is provided with three air intake branches 10, three air intake branches 10 connect nozzle adjustable support 4 respectively, and described nozzle adjustable support 4 is connected in main air inlet pipe 9, when caliber changes, be used for telescopic adjustment flame spray head and inside pipe wall clear distance, guarantee homogeneous heating; Described main air inlet pipe 9 one termination is connected with handwheel 7; Each air intake branch 10 is vertically equidistantly provided with some flame spray heads 11, and each flame spray head 11 arranges a shutoff 3, when pipe range is less than heater length, and can occluding member flame spray head according to demand; Adjacent air intake branch flame spray head 11 angles are 30 °; The merging of described three air intake branch 10 1 terminations is connected to house steward, and house steward connects air induction hose 8.
During this rotary-type external anticorrosive coating peeling heater work, rotary-type external anticorrosive coating peeling heater homogeneous heating, heating overall process does not contact with external anti-corrosion layer, has fundamentally stopped partial carbonization.When extraneous wind speed is larger, pipe one end can be done temporary plugging to reduce thermal loss.Be very effective in the application, compared with traditional heating mode, have reduce labour intensity, improve peeling efficiency, the advantage such as the scope of application is large, safety and environmental protection.
