Description

Technical Field

[0001] The invention belongs to the technical field of pipeline pickling equipment, and in particular relates to automatic pipeline pickling equipment. Background Art

[0002] The method of using acid solution to remove oxide scale and rust on the surface of steel is called pickling, which is a method of cleaning the metal surface. The pickling solution of the pickling process is generally a mixture of multiple acids. The existing galvanized steel pipe is pickled through pickling equipment.

[0003] Commonly used acids for pickling include inorganic acids such as hydrochloric acid, sulfuric acid, phosphoric acid, hydrofluoric acid, and aminosulfonic acid, and organic acids such as citric acid and EDTA. However, since acids are corrosive to metal equipment, especially inorganic acids, the corrosion is more serious. At the same time, the released hydrogen will diffuse into the metal, causing hydrogen embrittlement of the washed equipment. In addition, the large amount of acidic gas released will deteriorate the working conditions. Therefore, corrosion inhibitors should be added during pickling to inhibit the corrosion of metals in acidic media, reduce the amount of acid used, improve the pickling effect, and extend the service life of thermal equipment.

[0004] Chinese utility model patent CN221895134U discloses a galvanized steel pipe pickling device, including a pickling tank, a pickling chamber is arranged inside the pickling tank, a bottom chamber is arranged at the bottom of the pickling chamber, and side chambers are symmetrically arranged on both sides of the top of the pickling chamber, and a power mechanism for the flow of pickling liquid inside the pickling chamber is arranged inside the bottom chamber and the side chamber. By arranging the power mechanism in the pickling chamber, the effect of making the static pickling liquid in the pickling chamber flow is achieved, and the scouring force of the flowing pickling liquid can effectively wash away impurities and debris on the surface of the steel pipe, and take away the impurities from the surface of the steel pipe, so that the pickling process is more thorough, and the first shafted spiral blade and the second shafted spiral blade in the bottom chamber and the side chambers on both sides can be driven to rotate at the same time by the drive of the servo motor, and the pickling liquid in the pickling chamber is efficiently flowed by the rotation of the shafted spiral blade, and the impurities and debris on the surface of the steel pipe are washed away, thereby improving the pickling effect of the steel pipe.

[0005] Although the above-mentioned prior art can make the pickling liquid in the pickling chamber flow through the shaft spiral blade, this flow does not have a high impact force, so the flushing effect on impurities and debris on the surface of the steel pipe is not good, and some relatively stubborn impurities and debris will not be flushed out.
