Abstract

The invention discloses a pipeline iron scrap cleaner, and belongs to the technical field of iron scraps and welding slag cleaning in pipelines. The pipeline iron scrap cleaner includes a protection ring, a cleaning head, a cleaning rod and a fixing screw. The upper end of the protection ring is provided with a first cavity, and the lower end of the protection ring is provided with a second cavitycommunicating with the first cavity. The diameter of the first cavity is greater than the diameter of the second cavity. The cleaning head is located in the first cavity of the protection ring, and the cleaning head is a magnet and is provided with a through hole communicating with the second cavity. The cleaning rod is located below the second cavity of the protection ring. The fixing screw passes through the through hole of the cleaning head and the second cavity of the protection ring to connect to the cleaning rod. The pipeline iron scrap cleaner can timely clean the iron scraps splashedinto a pipeline when the pipeline is cut, and quickly clean the iron scraps and welding slag which block a water meter and a throttle orifice of a regulating valve, thereby saving the cleaning cost ofthe pipeline and being conductive to the safety of the pipeline.

Description

technical field [0001] The invention relates to the technical field of iron filings and welding slag removal in pipelines, in particular to a pipeline iron filings remover. Background technique [0002] In industrial production, gas-carrying operations on pipelines mainly involve gas cutting and welding. Usually, gas cutting or tee welding is performed on pipelines. When opening with gas cutting, a lot of iron filings will be blown into the pipe while cutting, and some iron filings will remain in the pipe due to grinding before gas welding. When the gas-carrying operation is completed and the pipeline (including air pipes, oil pipes, water pipes, etc.) resumes work, iron filings will be blown to the downstream pipeline equipment (such as water meters of oil production well stations, orifices of regulating valves) due to the impact of air flow or fluid. In the interior, especially after the welding of low-pressure pipelines is completed, there is no filtering equipment downs...
