Description

Technical Field

[0001] The invention relates to the technical field of pipeline anti-corrosion processing, and in particular to pipeline anti-corrosion processing equipment and a processing technology thereof. Background Art

[0002] Pipelines play an irreplaceable role in many fields such as oil, natural gas, water supply and drainage. However, due to long-term exposure to various complex environments, the outer wall of the pipeline is very susceptible to corrosion, which not only reduces its service life, but even causes safety accidents in serious cases, causing huge economic losses. Therefore, in order to ensure the safe and stable operation of pipelines and extend their service life, people generally use pipeline anti-corrosion processing equipment to perform anti-corrosion processing operations on the outer wall of the pipeline to improve the efficiency of pipeline use.

[0003] However, the existing pipeline anti-corrosion processing equipment has the following shortcomings:

[0004] When pipeline anti-corrosion processing equipment is performing anti-corrosion processing on the outer wall of the pipeline, it usually performs spraying and curing operations at the same time. At this time, the paint particles generated during the spraying operation will adhere to the surface of the curing lamp, blocking the light, resulting in uneven light irradiation, and then causing inconsistent degree of paint curing on the pipeline surface, which in turn affects the overall quality of pipeline anti-corrosion. At the same time, the paint particles attached to the surface of the curing lamp are also likely to cause corrosion to the curing lamp, reducing the service life of the curing lamp, that is, reducing the use effect of the pipeline anti-corrosion processing equipment.

[0017] A processing technology for pipeline anti-corrosion processing equipment comprises the following steps:

[0018] S1. When the outer wall of the pipeline needs to be anti-corrosion processed, the two double-hole racks are first moved to the appropriate position and installed, and then the pipeline body is placed on the two double-hole racks. Then, the activated carbon particles are placed into the porous shell by using the sealing cover. Then, a proper amount of anti-corrosion coating is injected into the storage box by using the sealing plug. Then, the non-ionic surfactant in the first storage box is released into the box by using the controller and the first electric valve. Then, the conveying structure connected to the pipeline body is started.

[0019] S2. When the conveying structure starts to start, the controller is used to start the paint pump and the air pump. Then, the paint in the storage box is conveyed to the inside of the annular nozzle by the cooperation of the started paint pump and the two connecting pipes. The pipe body inside the annular nozzle is sprayed. Then, the paint particles mixed in the air inside the shell are conveyed to the inside of the box by the cooperation of the started air pump, the two conveying pipes and the one-way valve. Then, most of the paint particles are retained inside the box by the cooperation of water and non-ionic surfactant.

[0020] S3, then using the cooperation of activated carbon particles and the sealing cover, the paint particles remaining in the air are retained inside the porous shell, and when the place where the pipe body is sprayed with paint moves to the inside of the second sleeve, the controller, the curing lamp, the second sleeve and the second sleeve cover are used to perform a curing operation on the pipe body inside the curing lamp. When the outer wall anticorrosion processing operation of the pipe body is completed, the conveying structure is directly closed, and then the air pump and the paint pump are closed by the controller, and then the curing lamp is closed by the controller, and then the pipe body is removed;

[0021] S4. Then, the four rotating plates are driven to rotate by the cooperation of the controller, the motor and the rotating rod. Then, the coagulant in the second storage box is released into the box by the cooperation of the controller and the second electric valve. Then, the paint particles in the box are formed into larger flocs by the cooperation of the four rotating rotating plates and the coagulant. Then, the water and flocs in the box are released into the filter barrel by the cooperation of the controller and the third electric valve. Finally, the above steps are followed to perform the outer wall anti-corrosion processing on other pipeline bodies.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. The present invention can prevent the paint particles from adhering to the curing lamp when the pipeline anti-corrosion processing equipment performs anti-corrosion processing on the outer wall of the pipeline, thereby causing uneven light irradiation, and further causing inconsistent curing degree of the paint on the pipeline surface, which in turn affects the overall quality of pipeline anti-corrosion, and also avoids the situation where the service life of the curing lamp is reduced, that is, the use effect of the pipeline anti-corrosion processing equipment is improved. When it is necessary to deal with the paint particles generated during the spraying operation, the sealing cover is first used to put the activated carbon particles into the interior of the porous shell, and then the first electric valve and the first storage box are used to release the non-ionic surfactant into the interior of the box, and then the air pump, two delivery pipes and the one-way valve are used to transport the air inside the shell and the paint particles mixed in the air to the interior of the box.

[0024] 2. The present invention then utilizes the combination of nonionic surfactant and water to retain most of the coating particles inside the box, and then utilizes the combination of activated carbon particles and a sealing cover to retain the coating particles remaining in the air inside the porous shell. When the outer wall anti-corrosion processing operation of the pipeline body is completed, the combination of the started motor and the rotating rod can be used to drive the rotating plate to rotate, and then the combination of the started second electric valve and the second storage box can be used to release the coagulant into the box. Then, the combination of the rotating rotating plate and the coagulant can form larger flocs of the coating particles inside the box, and then the combination of the started third electric valve can be used to release the water and flocs inside the box into the prepared filter barrel.

[0025] 3. The present invention can perform anti-corrosion processing on the outer wall of the pipeline by setting up a processing mechanism. When the outer wall of the pipeline needs to be processed with anti-corrosion, the four round rods and the four rotating tubes are first used to place the pipeline body between the two double-hole frames, and then the sealing plug is used to inject the anti-corrosion paint into the interior of the storage box. Then, the started conveying structure can be used to drive the pipeline body to move between the two double-hole frames. After that, the controller, the paint pump, the two connecting pipes and the annular nozzle are used to spray the paint on the pipeline body inside the annular nozzle.

[0026] 4. In the present invention, when the place where the paint is sprayed on the pipe body moves to the inside of the second sleeve, the pipe body can be cured by using the cooperation of the controller, the curing lamp, the second sleeve and the second sleeve cover. When the outer wall anti-corrosion processing operation of the pipe body is completed, the conveying structure is directly closed at this time, and then the paint pump and the curing lamp are turned off by using the cooperation of the controller, and then the pipe body that has completed the processing operation is removed, and then the outer wall anti-corrosion processing operation of other pipes can be performed by using the cooperation of the above-mentioned components.

At this time, the closed second electric valve 212 will stop releasing the coagulant into the interior of the box body 202, and then the interior of the box body 202 will remain. The paint particles in the water will react with the coagulant inside the box 202 with the cooperation of the four rotating rotating plates 208 to form larger flocs. Then the motor 206 is turned off by the controller 116. At this time, the closed motor 206 will stop the four rotating plates 208 from rotating. Then the prepared filter barrel is placed directly below the third electric valve 215. Then the third electric valve 215 is started by the controller 116. At this time, the started third electric valve 215 will release the wastewater and flocs inside the box 202 into the filter barrel. When the water and flocs inside the box 202 have completed the release operation, the third electric valve 215 can be directly closed by the controller 116. Then, the above-mentioned operation steps are followed to perform the outer wall anti-corrosion processing operation on other pipe bodies 3.
