Description

Technical Field

[0001] The present application relates to the field of steel bar rust removal, and in particular to a steel bar rust removal device. Background Art

[0002] At present, during the construction process, due to some special circumstances on the construction site (such as holidays), concrete pouring is not carried out after the steel bars are tied. Since the steel bars are exposed, they will rust under the corrosion of water vapor in the air. Before pouring concrete, the steel bars need to be derusted.

[0003] In the related art, there is a method of spraying rust remover on the surface of steel bars to clean the rust on the surface of steel bars. In actual operation, the rust remover is generally prepared first, and then placed in a sprayer. The operator carries the sprayer and sprays the rust remover in the sprayer on the steel bars to be treated. For some larger-scale steel bar rust removal treatments (such as foundation steel mesh, floor steel mesh, etc.), the operator needs to carry the sprayer and walk in various areas of the steel mesh, which can easily cause the steel mesh to bend. It is also time-consuming and labor-intensive, affecting the rust removal efficiency of the steel mesh. Summary of the Invention
