Problems solved by technology
The disadvantage of spraying anti-corrosion paint with high-pressure atomization spray guns is that 6-8 spray guns need to be arranged in the circumferential direction of the steel pipe, and the anti-corrosion paint after high-pressure atomization will easily block the spray guns
The high-pressure pump has harsh working conditions, severe wear and high failure rate

Abstract
The invention discloses a steel pipe anti-corrosion paint spraying device. An oil coating tank is provided with an inlet isolation door and an outlet isolation door on both sides of the oil coating tank. A steel pipe conveying roller table, a U-shaped spray ring and an annular air knife are arranged inside the oil coating tank. When the steel pipe enters the spraying device, a U-shaped spray ring with an adjustable nozzle is used to spray anti-corrosion paint on the circumferential direction of the steel pipe, and then the high-pressure compressed air in the annular air knife is blown to the surface of the steel pipe in the shape of a circular air curtain. Compressed air removes excess anti-corrosion paint on the surface of the steel pipe, so as to ensure the uniformity of the anti-corrosion paint spraying on the surface of the steel pipe, without hanging drops, and improve the appearance quality of the steel pipe body.
Description
technical field [0001] The invention relates to a round steel grinding quality inspection technology, and more specifically relates to a steel pipe anti-corrosion paint spraying device. Background technique [0002] According to the relevant standards, the steel pipe needs to be sprayed with anti-corrosion paint on the surface of the steel pipe body during production. The anti-corrosion paint has two types: transparent anti-corrosion paint and black paint. And after the anti-corrosion paint is dried and cured, the thickness of the paint film must reach a certain standard. At present, most of the steel pipe anti-corrosion paint spraying equipment adopts the method of high-pressure atomization spray gun to spray anti-corrosion paint. The disadvantage of spraying anti-corrosion paint with high-pressure atomizing spray guns is that 6-8 spray guns need to be arranged in the circumferential direction of the steel pipe, and the anti-corrosion paint after high-pressure atomization ...
