Urban sewer pipeline anti-corrosion process method

Abstract

The invention relates to an urban sewer pipeline anti-corrosion process method. The method comprises the following steps: slurry stirring: mixing and stirring a plurality of antirust materials through stirring equipment (A1) to obtain proper antirust slurry; slurry conveying: conveying the slurry treated in the step A into spraying equipment through slurry conveying equipment (B1); and pipeline corrosion prevention, specifically, rust removal polishing treatment is conducted on the inner wall of a pipeline through corrosion prevention equipment (C1), the inner wall of the pipeline is made to have the spraying condition, then the slurry treated in the step B is sprayed to the inner wall of the pipeline, and finally the inner wall, sprayed with the corrosion prevention slurry, of the pipeline is dried. According to the anti-corrosion process method, in operation procedures in the A-C step, the stirring equipment, the slurry conveying equipment and the corrosion prevention equipment need to be matched to complete corresponding treatment operation, the corrosion prevention equipment comprises an anti-corrosion grinding machine, the anti-corrosion grinding machine comprises a fixing disc, a drying machine, a spraying part and a grinding part, and the spraying part comprises a cylindrical shell, a rotating shaft, a rotating fan and a plurality of spraying assemblies.

Description

technical field [0001] The invention relates to the field of pipeline anticorrosion, in particular to an anticorrosion process method for urban sewer pipelines. Background technique [0002] Corrosion is a problem faced by all walks of life, especially gas and water pipelines. Some of the gas and liquid transported in the pipeline contain corrosive substances, so it is particularly important to carry out anti-corrosion treatment on the inner wall of the pipeline. At present, most of the anti-corrosion treatment of the inner wall of the pipeline is done manually. However, there are many anti-corrosion steps on the inner wall of the pipeline, and the pipeline is long and thin. It is inconvenient to apply it manually, the work efficiency is low, and it cannot effectively ensure that the inner wall of the pipeline is evenly smeared. There are pre-rust grinding and drying.
