Traditional pipeline corrosion protection methods often only treat the inner or outer wall of the pipeline, which not only makes the process cumbersome and time-consuming but also makes it difficult to guarantee the uniformity and consistency of corrosion protection effects on both the inner and outer walls. Especially when dealing with large or special-material pipelines, traditional methods are inadequate and cannot meet the requirements for efficient and high-quality corrosion protection. Therefore, a device for simultaneous corrosion protection of both the inner and outer walls of pipelines has been designed. Utility Model Content

[0019] The above describes the components, positional relationships, and connection relationships of the pipe external wall spraying device 3 and the pipe external wall cleaning device 4. (See attached diagram.) Figure 3 .

[0020] The treatment structure adjustment seat 6 has a through height adjustment groove 23. The integrated pipe inner wall treatment structure 5 consists of an integrated double-core conduit 24, a front fixing plate 25, a rear anti-slip fixing plate 26, a locking nut 27, and a conduit layered annular nozzle 28. The front fixing plate 25 is fixed to the rear section of the integrated double-core conduit 24, and the rear anti-slip fixing plate 26 is sleeved on the integrated double-core conduit 24. The rear end of the integrated double-core conduit 24 has a connecting thread 29. The integrated double-core conduit 24 passes through the height adjustment groove 23 on the treatment structure adjustment seat 6, and the front fixing plate 25 is tightly attached to the front of the height adjustment groove 23.

Two sets of conduit layered annular nozzles 28 are provided. The two sets of conduit layered annular nozzles 28 are respectively connected to the front section of the integrated double-core conduit 24, and the two sets of conduit layered annular nozzles 28 are respectively connected to the supply pipelines 9 connected to the airflow sandblasting supply equipment 7 and the anti-corrosion spraying supply equipment 8 through the integrated double-core conduit 24.

[0021] The above describes the components and corresponding connections of the treatment structure adjustment seat 6 and the integrated pipe inner wall treatment structure 5. (See attached diagram.) Figure 4 .

[0022] In practical applications, the working principle of this structure is as follows: First, the pipe to be treated is placed on the pipe balance clamping structure 2. Through the cooperation of the lower support roller 11 and the lower pressure roller 12, the pipe is ensured to be in a balanced and stable state so that subsequent anti-corrosion treatment operations can be carried out.

[0023] Next, adjust the height of the integrated treatment structure 5 on the treatment structure adjustment seat 6 according to the pipe specifications and treatment requirements. This can be done by loosening the locking nut 27, allowing the integrated dual-core conduit 24 to move up and down within the height adjustment groove 23. Once it reaches the appropriate position, tighten the locking nut 27 again, and use the front fixing plate 25 and the rear anti-slip fixing plate 26 to securely fix the integrated dual-core conduit 24 on the treatment structure adjustment seat 6.

[0024] Subsequently, the airflow sandblasting supply equipment 7 is activated. The airflow carrying sand particles enters the integrated dual-core conduit 24 through the supply pipeline 9 and is sprayed out from the layered annular nozzle 28 of the conduit connected to the airflow sandblasting supply equipment 7, sandblasting and cleaning the inner wall of the pipe to remove rust, oil, and other impurities, providing a good foundation for subsequent anti-corrosion spraying. After the sandblasting cleaning of the inner wall of the pipe is completed, the airflow sandblasting supply equipment 7 is turned off, and the anti-corrosion spraying supply equipment 8 is turned on. The anti-corrosion coating enters the integrated dual-core conduit 24 through the supply pipeline 9 and is then evenly sprayed out from the layered annular nozzle 28 of the conduit connected to the anti-corrosion spraying supply equipment 8, adhering to the cleaned inner wall of the pipe to form a dense anti-corrosion coating.

[0025] At the same time, the pipe outer wall spraying device 3 and the pipe outer wall cleaning device 4 are also working simultaneously. The pipe outer wall cleaning device 4 uses a single-sided nozzle 21 to spray high-speed airflow or abrasive to clean the outer wall of the pipe; while the pipe outer wall spraying device 3 uses a single-sided nozzle 21 to evenly spray anti-corrosion coating onto the outer wall of the pipe.

[0026] During the process of balanced clamping and advancement of the pipeline, the inner and outer walls of the pipeline can be cleaned and coated with anti-corrosion paint simultaneously, which greatly improves the efficiency of pipeline anti-corrosion treatment and ensures the uniformity and consistency of the anti-corrosion effect on the inner and outer walls of the pipeline.

[0027] The above description is a preferred embodiment of the present utility model. For those skilled in the art, any changes, modifications, substitutions and variations made to the implementation methods without departing from the principles and spirit of the present utility model, based on the teachings of the present utility model, still fall within the protection scope of the present utility model.
