Construction process of anti-corrosion thermal insulation coating

Abstract

The invention discloses an anti-corrosion heat-preservation coating construction technology, and relates to the technical field of building pipeline machining, the anti-corrosion heat-preservation coating construction technology is based on a machining device, and the anti-corrosion heat-preservation coating construction technology specifically comprises the following steps that firstly, a pipeline is lifted through lifting equipment; the machining device is used for clamping and fixing the two ends of the pipeline; secondly, the surface of the pipeline is treated through a machining device, dust and rust on the surface are removed, and the cleanliness of the surface of the pipeline is guaranteed; thirdly, the machining device is used for spraying the corrosion-resistant heat-preservation coating to the surface, in the process, the machining device drives the pipeline to rotate, and it is guaranteed that the coating is evenly sprayed; according to the dust removal device, the extension rod of the dust removal device extends to push the sponge base plate and the cambered surface sponge block to make contact with the surface of a pipeline, the cambered surface sponge block wipes the surface of the pipeline, dust and rust powder generated in the rust removal process are removed, and the cleanliness of the surface of the pipeline is guaranteed.

Description

technical field [0001] The invention relates to the technical field of construction pipeline processing, in particular to a construction process of an anti-corrosion thermal insulation coating. Background technique [0002] The general construction pipeline is to meet the needs of people's life and use. Such as building pipelines: tap water pipelines, domestic waste water pipelines, sewage discharge pipelines, natural gas pipelines, and heating pipelines. In order to ensure that some construction pipelines meet the purpose of use, it is necessary to spray anti-corrosion and thermal insulation coating on the surface of the pipeline. [0003] After searching, the patent document with the publication number of CN215235350U provides an anti-corrosion construction device for thermal insulation pipelines for water conservancy projects, including an iron base on which a conveying mechanism is installed, and the conveying mechanism is used for the steel pipe. For transportation, t...

Problems solved by technology

[0003] After searching, the patent document whose publication number is CN215235350U provides a kind of anticorrosion construction device for thermal insulation pipelines for water conservancy projects, including an iron base, and a conveying mechanism is installed on the iron base, and the conveying mechanism is used for steel pipes Transportation, the conveying mechanism first conveys the steel pipe into the dust removal mechanism, the dust removal mechanism is a ring-shaped fan without blades to remove dust from the steel pipe, and then the conveying mechanism conveys the steel pipe into the painting mechanism for Spray paint, then the conveying mechanism conveys the steel pipe into the air-drying mechanism for air-drying, and finally the conveying mechanism conveys the steel pipe out, and the dust removal mechanism is an annular fan, which cleans the dust on the steel pipe without dead ends, and the steel pipe passes through the ring The dust on the air shell will be blown clean, and the dust removal mechanism also solves the problem that the dust on the outer wall of the pipe affects the painting effect in the past

[0004] But the above-mentioned patent has the following deficiencies: the above-mentioned patent adopts a ring-shaped fan without blades to remove dust from the steel pipe, but such dust removal effect is limited, such as dirt and foreign matter adhering to the surface of the pipe, and some metal pipe surfaces may There will be local corrosion, which cannot be cleaned by a single blower, so that the adhesion of the coating will still be affected during the subsequent spraying process, so there are limitations
