Description

Technical Field

[0001] The invention relates to the technical field of spraying devices, in particular to a spraying device for anti-corrosion treatment of the surface of a seamless steel pipe. Background Art

[0002] During the operation of the heat exchanger, the seamless steel pipe may come into contact with various corrosive media, such as acid, alkali, salt solution, etc. These media will react chemically with the surface of the steel pipe, causing corrosion of the steel pipe. Through anti-corrosion spraying, a layer of chemically stable coating is formed on the surface of the steel pipe, which can effectively isolate the contact between the steel pipe and the corrosive medium, prevent the occurrence of chemical reactions, and thus protect the steel pipe from chemical corrosion. However, if the spraying is uneven, the coating on some parts of the steel pipe will be too thin. These weak points cannot provide sufficient protection and are easily corroded by external corrosive media such as moisture, acid and alkali solutions, thereby causing local corrosion, such as pitting corrosion and crevice corrosion, which reduces the service life of the steel pipe.

In the utility model, the uniform spraying of the steel pipe is achieved through the clamping action inside the rotating plate combined with the first motor driving its rotation, and the hot air blower dries the steel pipe during the process, thereby ensuring the spraying effect and improving the efficiency.

[0004] Today's steel pipe spraying devices are mostly suitable for straight steel pipes. The serpentine seamless steel pipe used in the heat exchanger has bends, and there are differences in the spraying paths inside and outside the bends. When spraying all surfaces at the same time, it is difficult to ensure the uniformity of the spraying inside and outside, which can easily lead to thinner spraying on the outside, affecting its protective effect, or too much spraying on the inside causing wall hanging and other problems.

The direction of the serpentine rail 202 is corresponding to the direction of the serpentine steel pipe 6 for a heat exchanger. When the movable slider 203 moves along the serpentine rail 202, it can move around the two sides of the serpentine steel pipe 6 for a heat exchanger with the nozzle in the transmission assembly 3 at the top thereof.

When in a straight line, the first path belt 801 and the second path band 802 are arranged parallel to the serpentine slide rail 202, and the length of the straight section is consistent with the length of the straight section of the serpentine slide rail 202 and the straight section of the serpentine steel pipe 6 for the heat exchanger.
