Novel dredging equipment for petroleum pipeline

Abstract

The invention discloses novel dredging equipment for a petroleum pipeline, and belongs to the field of pipeline dredging equipment. The novel dredging equipment for the petroleum pipeline comprises amain unit, a dredging pipe and a conical drill bit, wherein the inside of the main unit is fixedly connected with a rotating shaft; the left end of the dredging pipe is fixedly connected with the rotating shaft; the right end of the dredging pipe is fixedly connected with the conical drill bit; the right end of the main unit is fixedly connected with an annular threaded shafts; a petroleum storagebox is arranged on the outer surface of the annular threaded shaft, and is in threaded connection with the annular threaded shaft; the right end of the petroleum storage box is fixedly connected withan annular petroleum delivering tube; the dredging tube is positioned in the middle of an annular petroleum delivering tube; a through hole is formed in the outer surface of the annular petroleum delivering tube; and a discharge tube is arranged at the lower end of the petroleum storage box, and is in threaded connection with the petroleum storage box. When the pipeline is dredged, residual or blocked petroleum in the pipeline can be absorbed and is recycled.

Description

technical field [0001] The invention relates to the field of pipeline dredging equipment, and more specifically relates to a new type of dredging equipment for oil pipelines. Background technique [0002] In the process of oil development and transportation, often due to mixed impurities in crude oil, or due to the minimum outbound oil temperature and minimum output restrictions, the pipelines used to transport oil will be blocked after a period of use, which is very important for oil transportation a puzzle. In the prior art, a spiral dredging tool is usually used or operated by a soft spring, which solves the problem of pipeline blockage to a certain extent. [0003] However, the existing oil pipeline dredging equipment cannot absorb residual or clogged oil in the pipeline when dredging the pipeline, which has caused a waste of oil resources to a certain extent. Contents of the invention [0004] 1. Technical problems to be solved [0005] Aiming at the problems exist...
