AI Technical Summary

Technical Problem

Traditional anti-rust spraying devices for the welded area of ​​corrugated steel web have a long manufacturing cycle, which can easily lead to accelerated rust and structural deterioration. In addition, dust and debris remaining on the surface before spraying reduces the adhesion of the coating and affects the anti-corrosion performance.

Method used

A rust-preventive spraying device was designed, comprising a housing, a spraying assembly, a dust collection assembly, and a conveyor belt. A high-pressure pump drives the paint atomization spraying, a motor drives a brush to clean the surface, a dust collection head removes dust, and a chain and gear mechanism achieves uniform spraying.

Benefits of technology

It shortens the manufacturing and installation cycle, improves the uniformity and efficiency of anti-rust spraying, ensures the adhesion of the coating, prevents rust, and enhances anti-corrosion performance.

Abstract

The utility model relates to the technical field of anti-rust of corrugated steel webs, and discloses an anti-rust spraying device for the welding area of corrugated steel webs, which comprises a box body. Inside the box body, there are respectively a primer storage bin, an intermediate paint storage bin and a topcoat storage bin. A spraying component is arranged inside the box body. The spraying component includes a spray head, and a diversion pipe is fixedly connected to the outer wall of the spray head. One end of the diversion pipe is fixedly connected with a telescopic hose, and one end of the telescopic hose is fixedly connected with a first conveying pipe. One end of the first conveying pipe is fixedly connected with a storage tank, and a high-pressure pump is arranged on one side of the outer wall of the storage tank. The output end of the high-pressure pump is fixedly connected with a second conveying pipe. In the utility model, it effectively avoids the problem that the traditional anti-rust spraying device for the welding area of corrugated steel webs has a long cycle from production to on-site installation, which is likely to cause the corrosion to accelerate the structural deterioration, and achieves the effect of uniformly anti-rust spraying on the corrugated steel webs.
