Abstract

The invention relates to a passive oil conveying pipeline cleaner and belongs to the technical field of oil conveying pipeline dredging equipment. The pipeline cleaner comprises a sun gear, planetary gears, a center gear and an impeller. The two ends of the sun gear are provided with a front sealing plate and a back sealing plate through fixing rods respectively. A planetary gear shaft is arranged between the front sealing plate and the back sealing plate in a triangle shape. The planetary gears are movably arranged on the planetary gear shaft respectively. The center gear is arranged in the sun gear between the planetary gears. The impeller is arranged in the center gear. The planetary gears are in meshed connection with the center gear and the sun gear respectively. Power is provided for the pipeline cleaner through raw oil conveyed in a pipeline, rotating blade cutting design of interference fit of a traditional descaling device and the pipeline is changed, damage on the pipeline is effectively lowered, descaling effect is improved, loss caused by production stopping is lowered, and oil conveying efficiency is effectively guaranteed. According to the pipeline cleaner, through the similarity principle, different sizes can be designed, so that the requirements of washing work of pipelines with different inner diameters are met.

Description

technical field [0001] The invention relates to a passive oil pipeline pig and belongs to the technical field of dredging equipment for oil pipelines. Background technique [0002] According to the relevant regulations and norms of the country, oil pipelines need to be regularly pigged and inspected. Through the cleaning of the pipelines, the efficiency of crude oil transportation and the service life of the pipelines can be improved; the inspection of the pipelines can ensure the safety of oil transportation and ensure Safe Production. [0003] At present, the cleaning methods of oil pipelines mainly include chemical wax removal, cleaning agent method, thermal wax removal (steam, hot water, hot oil), microbial wax removal, electromagnetic heating wax removal, high-pressure jet wax removal, mechanical wax removal, etc. In addition to mechanical wax removal, there are various problems in other wax removal methods, such as production stoppage, high cost, environmental polluti...
