Abstract
The utility model discloses a small-calibre steel pipeline anti-corrosion layer painting equipment, belonging to the equipment which is painted to avoid the damage to the exterior of the pipes or similar articles. The small-calibre steel pipeline anti-corrosion layer painting equipment comprises an original transmission wheel group A which pushes the steel pipe to advance rotatablely, an original transmission wheel group B, a middle frequency heater, epoxy powder spraying equipment, an adhesive extruder, a polyethylene extruder and a cooling water pool. The small-calibre steel pipeline anti-corrosion layer painting equipment is characterized in that a new transmission wheel group is arranged between the epoxy powder spraying equipment and the adhesive extruder. The technical proposal of the utility model effectively solves the problem of unstable quality during the painting of the anti-corrosion layer which is caused by the pulsation and displacement that is easily caused by that the spanning distance between the last group of transmission wheel and the water cooling pool before the middle frequency heating is longer, no supporting points is arranged between the transmission wheel and the water cooling pool, and the steel pipe (with the calibre of 25-108) has light weight and soft rigidity. The small-calibre steel pipeline anti-corrosion layer painting equipment can be used for the technical reconstruction of anti-corrosion layer production line of the existing steel pipeline.
Description
Technical field
The utility model belongs to the equipment that the infringement for the outside that prevents pipe or similarity piece applies.
Background technology
Be used for oil, gas, water, mud blending agent steel conveyance conduit and need apply anticorrosive coat to it for the antiseptic property that improves its outer surface, the polytene pipeline anticorrosive coating technology is with its excellent physical property, good resistance to chemical corrosion, and the pipeline environment of extremely low water and oxygen permeability and creation green has obtained to use comparatively widely in China's pipeline corrosion protection engineering.Technology commonly used has coated formula aseptic technic of O film one and side direction wound form anticorrosion process, side direction wound form corrosion-resistant technical advantage is embodied in glued membrane and the horizontal layering of PE film, multi-lay winding, the strong bonded that at high temperature reacts together, effectively overcome the defective that the whole appearance of anticorrosive coat is ftractureed rapidly and come off, thereby reach the effect that prolongs the whole anticorrosion life-span, oil, Gas Industry obtain a large amount of applying at home at present.In the production line of existing this technology of use, the primary structure of steel pipe corrosion-proof apparatus is to comprise that two row are on the chevron shaped drive support that is installed on the base drive is housed, steel pipe is positioned at two biographies driving wheels top, steel pipe under the driving of drive in the shape of a spiral shape advance, this equipment is applicable to the side direction wound form of Φ 108 above bore steel pipes anticorrosion, since steel pipe when helical form is advanced before heating in medium frequency between last group drive and cooling water flow in pond span big and do not have a strong point, the weight of Φ 25～Φ 108 bore steel pipes own is lighter, rigidity is softer, is easy to generate pulsation, displacement; Can't can't carry out the anticorrosion coating of side direction wound form to Φ 108 and following bore steel pipe.
The utility model content
In order to overcome existing coating device Φ 108 is reached the deficiency that following bore steel pipe can't carry out the anticorrosion coating of side direction wound form, the utility model provides a kind of small diameter steel pipeline anticorrosion coating coating device, and this small diameter steel pipeline anticorrosion coating coating device can can't carry out the anticorrosion coating of side direction wound form to Φ 108 and following bore steel pipe.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of small diameter steel pipeline anticorrosion coating coating device, comprise promoting former driving wheel group A, former driving wheel group B, intermediate frequency heater, epoxy powder spraying equipment, adhesive extruder, polyethylene extruder, the cooling pond that the steel pipe rotation is advanced, it is characterized in that: between epoxy powder spraying equipment and adhesive extruder, the new transmission wheels are housed.
Described new transmission wheels are the drive made from heat resistant rubber on the chevron shaped drive support that is installed on the base by two and form.
The disclosed small diameter steel pipeline anticorrosion coating of the utility model coating device is owing to be equipped with the new transmission wheels at existing production line between epoxy powder spraying equipment and adhesive extruder, make steel pipe that Φ 25～Φ 108 bores need carry out anticorrosion coating under the driving of this driving wheel group in the shape of a spiral shape steadily advance.Can effectively overcome in the existing equipment because before heating in medium frequency between last group drive and the cooling water flow in pond span big and do not have a strong point, the weight of Φ 25～Φ 108 bore steel pipes own is lighter in addition, rigidity is softer, is easy to generate pulsation, displacement and causes the unsettled difficult problem of quality when carrying out the anticorrosive coat coating; Use the technical program can carry out side direction wound form anticorrosive coat to Φ 25～Φ 820mm bore steel pipe and apply, check the coating steel pipe of all kinds of bores all to reach related standards through quality testing department to the existing steel pipeline anti-corrision layer coating production line back production line that undergoes technological transformation.This modification scheme has the advantage of small investment high efficiency.
