Description

Technical Field

[0001] The utility model relates to the technical field of pipe spraying, in particular to an anti-corrosion device for steel pipes. Background Art

[0002] In order to prevent rust and corrosion on the outer layer of steel pipe fittings, different surface coatings need to be applied after polishing to enhance its chemical properties, maintain surface gloss and slow down the oxidation rate. When spraying the coating, atomizing nozzles are mainly used to maintain uniform coverage.

[0003] An existing anti-corrosion treatment equipment for the outer layer of steel pipes (Announcement No.: CN220969601U) has at least the following disadvantages: the above-mentioned device transfers the steel pipe to the spray box and the drying box through a pipe pushing wheel, and the dried steel pipe is pulled out by the moving roller. By pushing and sending, the problem that the clamping points cannot be covered by the paint is solved. However, the position and spacing of the spray box and the drying box are fixed. When transporting shorter steel pipes, it is easy for the steel pipe to be difficult to effectively transport out of the spray box and the drying box, resulting in the mobile roller being unable to pull the shorter steel pipe, which makes it difficult for the steel pipe fittings to be effectively sprayed and dried, and thus causes the anti-corrosion effect of the steel pipe fittings to be poor. For this reason, we propose the present utility model. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose an anti-corrosion device for steel pipe fittings.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The anti-corrosion equipment is provided with a fixed structure and a conveying structure. The staff starts the first motor, which drives the second bidirectional screw to rotate. The rotation of the second bidirectional screw drives the two fixed plates to move closer to or away from each other, so that it can adapt to steel pipes of different lengths. The tensioning blocks on one side of the two movable plates are inserted into the two ends of the steel pipe. The first bidirectional screw is rotated. The rotation of the first bidirectional screw drives the two tensioning blocks to move away from each other, so that the tensioning blocks are tensioned and fixed inside the steel pipe.

The second motor drives the mounting plate and the steel pipe into the spray box and the drying box through the screw for spraying and drying to perform anti-corrosion treatment. The treated steel pipe is removed from the drying box under the action of the screw. Therefore, there is no need to clamp the outer surface of the pipe to perform anti-corrosion treatment on pipes of different lengths, thereby improving the anti-corrosion effect of the steel pipe.
