Abstract
A kind of new device for pipeline outer wall anticorrosive coating peeling is mainly used for the stripping of pipeline outer wall erosion resistant coating.Mainly it is made of glass fabric, electromagnetic induction coil, soft magnet plate, temperature measuring equipment, temperature controller, variable-frequency power sources, pipeline body, erosion resistant coating.Vortex is formed in pipeline body realize heating after the high-frequency alternating current to electromagnetic induction coil that power frequency electric passes through variable-frequency power sources output 20-40KHz.Glass fabric plays the role of heat-insulated, insulating effect, and soft magnet plate externally plays armoured magnetic field, internally plays enhancing magnetic field, and the temperature of temperature measuring equipment, temperature control controller needed for erosion resistant coating softening controls the output of variable-frequency power sources.It has the characteristics that reasonable for structure, temperature-controllable and do not influenced by outside environmental elements, the thermal efficiency is high, safe and reliable to operation.
Description
Technical field
The present invention is a kind of new device for pipeline outer wall anticorrosive coating peeling, is related to the technology of pipeline anticorrosion coating stripping
Field.
Background technology
It needs to carry out the erosion resistant coatings such as the pitch, epoxy powder, 3PE of pipeline outer wall during pipeline construction, dimension repairing
Stripping, existing anticorrosive coating peeling are mainly carried out by the diathermanous mode of baked wheaten cake, mechanical grinding, infrared ray ecto-entad.These
Stripping mode has the following problems：1, since oil, gas belong to inflammable and explosive object, safe thing is easily caused using the method for baked wheaten cake
Therefore.2, mechanical grinding working efficiency is low, cannot be satisfied site operation requirement, and easily damaged pipeline body.3, infrared ray is by outer
Inwardly diathermanous mode is affected by environment big, and working efficiency improves unobvious, can not be removed in the case of relatively low temperature.
Invention content
Present invention aims to overcome that in place of above-mentioned the deficiencies in the prior art, provide after one kind makes pipeline body directly generate heat
Reach the electromagnetic induction heater that softening erosion resistant coating realizes stripping.
The present invention mainly by glass fabric 1, electromagnetic induction coil 2, soft magnet plate 3, temperature measuring equipment 4, temperature controller 5,
Variable-frequency power sources 6, pipeline body 7, erosion resistant coating 8 are constituted.The present invention can be realized by following frame mode：One kind being used for pipeline
The electromagnetic induction heater of anticorrosive coating peeling, including it is wrapped in glass fibre after soft magnet plate 3 is installed on electromagnetic induction coil 2
It is placed on erosion resistant coating 8 after formation ribbon type heating device in cloth 1 and is connected with conversion electromagnetic induction heating power supply 6.Temperature measuring equipment
It is connected with temperature controller 5 behind 1 surface of glass fabric, temperature controller 5 connects variable-frequency power sources control terminal.The present invention
Principle be power frequency electric pass through variable-frequency power sources export 20-40KHz high-frequency alternating current to electromagnetic induction coil after in pipeline body
Interior formation numerous vortices fast heating achievees the effect that soften erosion resistant coating, to realize the stripping of erosion resistant coating and pipeline body.Glass
Glass fiber cloth plays the role of heat-insulated, insulating effect, and soft magnet plate externally plays armoured magnetic field, internally plays enhancing magnetic field, thermometric
The temperature of device, temperature controller needed for erosion resistant coating softening controls the output of conversion electromagnetic induction heating power supply.
The present invention changes the drawbacks of original pipeline anticorrosive coating peeling mode, provides after one kind makes pipeline body directly generate heat
Soften erosion resistant coating to realize the electromagnetic induction heater of stripping.Compared with prior art, the present invention has the following advantages：Its
One, safe to use, temperature control is accurate.Second, heating speed is fast, working efficiency is improved.Third, since the mode of heating is by introversion
It is outer diathermanous, it is not influenced by hot-cool environment.
Description of the drawings
Fig. 1 is structure of the invention figure.
1 is glass fabric；2 be electromagnetic induction coil；3 be soft magnet plate；4 be temperature measuring equipment；5 be temperature controller；6 are
Variable-frequency power sources；7 be pipeline body；8 be erosion resistant coating.
Specific implementation mode
Illustrate specific implementation mode below in conjunction with the accompanying drawings.
Specific embodiment 1：
A kind of electromagnetic induction heater for pipeline anticorrosion coating stripping, including it is soft by being installed on electromagnetic induction coil 2
It is wrapped in after magnetic sheet 3 in glass fabric 1 after forming ribbon type heating device and is disposed transversely on erosion resistant coating 8 rear and variable-frequency power sources
6 are connected.Temperature measuring equipment is connected after being mounted in 1 surface of glass fabric with temperature controller 5, and temperature controller 5 connects variable-frequency power sources
Control terminal.Power frequency electric exports the high-frequency alternating current of 20-40KHz to electromagnetic induction coil 2 by conversion electromagnetic induction heating power supply 6
So that the erosion resistant coating 8 of outer wall is softened after forming numerous vortices fever in pipeline body 7 afterwards, reaches erosion resistant coating and pipeline body 7
Separation.Glass fabric 1 plays heat-insulated, insulating effect, and soft magnet plate 3 externally plays armoured magnetic field, internally plays enhancing magnetic field
Effect, the temperature control conversion electromagnetic induction heating power supply 6 of temperature measuring equipment 4, temperature control controller 5 needed for erosion resistant coating softening
Output.
