[0001] The utility model relates to the field of spraying, in particular to surface spraying equipment for anti-corrosion treatment of seamless steel pipes. Background Art

[0002] A steel pipe is a long strip of steel with a hollow cross-section, whose length is much greater than its diameter or circumference.

[0003] In the prior art, with the development of industry, seamless steel pipes are increasingly used in the petroleum, chemical, natural gas and other industries. However, since the surface of the seamless steel pipe is often exposed to harsh industrial environments, it has become a necessary process to protect the seamless steel pipe by spraying anti-corrosion coatings on the surface. The anti-corrosion treatment is often carried out by a sprayer. The steel pipe is fixed in a spraying cabin in the sprayer, and then multiple groups of nozzles in the spraying cabin are used to spray the steel pipe to achieve anti-corrosion treatment of the seamless steel pipe.

[0004] However, when the nozzle of the spray machine sprays the steel pipe, the sprayed anti-corrosion coating will adhere to the steel pipe. After a long time, it will easily cause uneven thickness of the anti-corrosion coating adhered to the surface of the steel pipe, affecting the corrosion resistance of the seamless steel pipe.

Since one end of the guide rod 17 is fixed to the surface of the rotating plate 6 and the other end is fixed to the surface of the connecting block 14, the rotation of the rotating plate 6 will drive the mounting ring 12 to rotate;

[0029] A discharge port 10 and a spraying tank 2 are provided on the side surface of the spraying machine body 1. A spraying pipe 3 is provided on the side surface of the spraying machine body 1. The spraying pipe 3 is provided in multiple groups, and the multiple groups of spraying pipes 3 are symmetrically distributed.
