Cleaning anticorrosion device for inner wall of oil pipeline

Abstract

The invention discloses a cleaning and anticorrosion device for the inner wall of an oil pipeline, which includes a transfer mechanism, an adjustment mechanism and a cleaning mechanism. The transfer mechanism includes a hollow socket sleeve and an I-shaped hollow sleeve. A hollow transmission rod connected with the inner cavity is connected, and the right end of the hollow transmission rod is connected with a paint transfer box connected with each other. The cleaning mechanism includes a first hinged seat, a second hinged seat, two first hinged rods, and two second hinged rods. The hinge rod and two mutually symmetrical arc-shaped PVC scrapers, the adjustment mechanism includes a threaded column and a threaded sleeve, the left end surface of the threaded column is fixedly connected with the center of the right end surface of the first hinge seat, and the right end surface of the threaded sleeve passes through the turntable It is rotatably connected with the center of the left end face of the second hinged seat. The invention realizes the synchronous operation of cleaning and anti-corrosion painting, so as to prevent the purity of crude oil liquid from being affected by rust stains in the long-term use of oil pipelines, prevent the oil pipelines from being corroded due to rust, and reduce potential safety hazards.

Description

technical field [0001] The invention relates to the related technical field of oil exploitation pipeline cleaning and anticorrosion, in particular to a cleaning and anticorrosion device for the inner wall of an oil pipeline. Background technique [0002] Petroleum, one of the main objects of geological exploration, is a viscous, dark brown liquid known as "industrial blood"; there are oil reserves in some areas of the upper crust; the main components are various alkanes, cycloalkanes, aromatic hydrocarbons The processing of petroleum needs to be assisted by pipelines, so the cleaning and anti-corrosion work of the inner wall of the pipeline is particularly important. Once rust stains appear on the inner wall of the oil transportation pipeline or cracks appear in the pipeline due to corrosion, once the crude oil solution is mixed with Rust stains or leakage will increase the cost of subsequent processing, and there are certain safety hazards, which is very inconvenient.

[0002] Petroleum, one of the main objects of geological exploration, is a viscous, dark brown liquid known as "industrial blood"; there are oil reserves in some areas of the upper crust; the main components are various alkanes, cycloalkanes, aromatic hydrocarbons The processing of petroleum needs to be assisted by pipelines, so the cleaning and anti-corrosion work of the inner wall of the pipeline is particularly important. Once rust stains appear on the inner wall of the oil transportation pipeline or cracks appear in the pipeline due to corrosion, once the crude oil solution is mixed with Rust stains or leakage will increase the cost of subsequent processing, and there are certain safety hazards, which is very inconvenient. Therefore, a cleaning and anti-corrosion device for the inner wall of oil pipelines is designed here to solve the above problems.
