Abstract
The invention relates to a pipe inner coating coater and a coating method for pipe inner coating operations. The coater comprises front and back coaters, wherein bodies of the front and back coaters are hollow cylinders, the head ends are closed, and the tail ends are provided with leather bowls; more than one layer of scrapers are arranged on the outer surfaces of the hollow cylinders; a front leather bowl is arranged at the head end of the hollow cylinder of the front coater; a scraper is arranged at the head end of the hollow cylinder of the back coater; radial holes are formed in the side surface of the hollow cylinder of the front coater; and axial holes are formed in the scraper of the back coater. The coating method comprises the following coating steps: firstly, the front and back coaters are mounted in a pipe to be coated in sequence, and paint is added therebetween; and then, compressed air is injected in the back end of the back coater. As the coater is wholly molded through compression by a nonmetal elastic material, and is provided with multiple layers of scrapers and the leather bowl at the tail, the coater can pass through a small-radius elbow; and when the coater passes through such places as elbow and flange connecting places, no blow-by phenomenon can be generated, and the coating thickness is uniform.
Description
Technical field
The present invention relates to a kind of pipeline coating coating tool and technique, especially a kind of pipeline coating applicator and coating method thereof.
Background technology
Be a kind of more advanced pipeline internal corrosion application means at the inwall of built fluid-transporting tubing overall application liquid paint coatings, be not only applicable to newly-built pipeline, also can be used for the interior anticorrosive coat renovation of old pipeline.When carrying out the unitary fluid paint spraying of inner-walls of duct, usually needing to use special applicator to promote coating and advancing.The squeezing and coating device used in constructing at the scene is at present generally the structure of the fixing multiple leather cup of steel skeleton series connection, short-radius bend cannot be passed through, and when by the place such as elbow, flange connections, easily there is gas-blowing phenomenon, finally cause coating became uneven, even may cause the mass defect such as holiday and local piling.
Summary of the invention
In order to solve the problems of the technologies described above, invent a kind of pipeline coating applicator and coating method thereof, having used tool and method operation of the present invention, applicator can pass through short-radius bend, and when by the place such as elbow, flange connections, there will not be gas-blowing phenomenon, coating thickness is even.
Technical scheme of the present invention is as follows:
A kind of pipeline coating applicator, comprise front applicator and rear applicator, the main body of front applicator and rear applicator is hollow cylinder, the head end of hollow cylinder is closed, tail end establishes leather cup, the outer surface of hollow cylinder is provided with the scraper plate of more than one deck, and scraper plate is disc-shaped, is looped around on hollow cylinder; The head end of front applicator hollow cylinder is provided with front leather cup; The head end of rear applicator hollow cylinder arranges a slice scraper plate; There is radial aperture the side of the hollow cylinder of front applicator; Rear applicator is provided with axial aperture on scraper plate.
Preferred embodiment one, front applicator and rear applicator adopt non-metallic elastic material integral die shaping.
Preferred embodiment two, the material of front applicator and rear applicator is polyurethane, polyester or synthetic rubber.
The coating method of a kind of pipeline coating applicator of the present invention, its step is,
A, front applicator, rear applicator are loaded pipeline to be applied successively, and add coating between front applicator, rear applicator;
B, backward applicator rear end injecting compressed air.
Compared with prior art, the invention has the beneficial effects as follows, have employed the shaping applicator of non-metallic elastic material integral die owing to devising, make applicator of the present invention to pass through short-radius bend; Again owing to being provided with multilayer scraper plate and afterbody leather cup on forward and backward applicator, make instrument of the present invention when by the place such as elbow, flange connections, even if applicator is squeezed occur local deformation, multilayer scraper plate on applicator and leather cup also all can not lose sealing effectiveness, thus there will not be gas-blowing phenomenon; Meanwhile, multilayer scraper plate and afterbody leather cup can make coating thickness more even.
Accompanying drawing explanation
Simply describing the present invention above, next describing the present invention further, in detail with reference to describing the drawing of following specific embodiment of the present invention.These drawings only describe some typical embodiments of this invention, therefore can not think to limit the scope of the invention.In these drawings:
Fig. 1 is the structural representation of applicator before the present invention.
Fig. 2 is the sectional view at A-A place in Fig. 1.
Fig. 3 is the structural representation of applicator after the present invention.
Fig. 4 is the sectional view at B-B place in Fig. 3.
Fig. 5 is coating method schematic diagram of the present invention.
Detailed description of the invention
See Fig. 1 and Fig. 2, the main body of front applicator is hollow cylinder 1, and the head end 3 of hollow cylinder 1 is closed, and tail end establishes leather cup 5, and the outer surface of hollow cylinder 1 is provided with the scraper plate 6 of more than one deck, and scraper plate 6 is disc-shaped, is looped around on hollow cylinder 1; The head end of front applicator hollow cylinder 1 is provided with front leather cup 7; There is radial aperture 8 side of the hollow cylinder 1 of front applicator.
See Fig. 3 and Fig. 4, the structure of rear applicator is close with front applicator, and its main body is also hollow cylinder 1, the head end 3 of hollow cylinder 1 is closed, and tail end establishes leather cup 5, and the outer surface of hollow cylinder 1 is provided with the scraper plate 6 of more than one deck, scraper plate 6 is disc-shaped, is looped around on hollow cylinder 1; The head end of rear applicator hollow cylinder 1 does not have leather cup, but arranges a slice scraper plate; Rear applicator is provided with axial aperture 9 on scraper plate 6.
In order to make coating not flow out to the front and back of applicator in operation process, remaining between forward and backward applicator better, between the front leather cup 7 of front applicator and ground floor scraper plate, not establishing radial aperture; Least significant end a slice scraper plate of rear applicator does not establish axial aperture.
In order to few material, reduce wall thickness, and the side wall strength of hollow cylinder can be ensured, hollow cylinder 1 inside is provided with waling 2.
In order to easy to operate during operation, head end 3 end is provided with draw ring 4.
In order to by minor diameter elbow, front applicator and rear applicator should easily bend, and therefore material can adopt non-metallic elastic material, and integral die is shaping.Integral die is shaping is known technology.Available material has polyurethane, polyester or synthetic rubber etc.
See Fig. 5, the coating method of a kind of pipeline coating applicator of the present invention, its step is,
A, front applicator 10, rear applicator 11 are loaded pipeline to be applied successively, and add coating 12 between front applicator, rear applicator;
B, backward applicator rear end injecting compressed air.
Compressed air promotes applicator and coating is advanced forward, coating enters the space between multilayer scraper plate through radial aperture 8 and axial aperture 9 under the effect of the pressure, and even blade coating, on tube wall, forms uniform coating 13 after rear applicator under the effect of scraper plate.
