Description
Technical Field

Background
The pipeline can deposit water scale on the inner wall because the conveying medium contains mineral substances and is used for a long time, and the water scale is difficult to remove and becomes thicker and thicker due to daily accumulation, so that the effective conveying caliber of the pipeline is reduced. Especially for pipes carrying hot water, scale deposits are very likely to form on the inner walls of the pipes. The scale deposit can form very big additional head loss when the pipeline carries liquid medium at the pipeline inner wall, increases the transportation cost, even unable normal transport forms great potential safety hazard.
At present, no practical and effective method is available for the problem of scale formation in pipelines, and for pipelines exposed outside, the scale formation is shaken off by knocking the pipelines to remove internal scale, but the method cannot be implemented for pipelines which are embedded underground, on walls or inaccessible to workers, and the effectiveness of scale removal cannot be evaluated. The other descaling method is to dissolve the scale in the pipeline through a specific solution such as hydroxypropionic acid, cation exchange resin and the like by chemical reaction and finally discharge the scale, but the method is often high in cost and only suitable for pipelines with short length and small caliber, and the method is also not suitable for certain pipelines with food safety requirements.
In view of various problems existing in the prior pipeline descaling, the invention provides a novel pipeline descaling robot. The scale is removed by adopting a pure physical mode, so that the pipeline is not subjected to toxic and harmful risks, and is not influenced by the position of the pipeline, whether the pipeline is exposed to the external environment or not and the scale of the pipeline. The robot directly goes deep into inside the pipeline, polishes the clearance and realizes the scale removal to the pipeline inner wall. The effectiveness of pipeline descaling is ensured, and the use and maintenance cost of the pipeline is reduced.
Therefore, the workers in the field are dedicated to research on a pipe descaling robot suitable for descaling and cleaning various pipes.
