Mechanical petroleum pipeline inner wall impurity cleaning device

Abstract

The invention discloses a mechanical petroleum pipeline inner wall impurity cleaning device which comprises a frame table plate, a positioning mechanism, a driving gearbox and a servo motor. A first lead screw is mounted on the frame table plate through a plurality of lead screw seats, the servo motor drives the first lead screw to rotate, a first lead screw nut is mounted on the first lead screw,the first lead screw nut and the first lead screw form screw pair transmission, the driving gearbox is fixedly mounted on the first lead screw nut, a motor is mounted in the driving gearbox, a rotating shaft is connected with an output end of the motor, a second lead screw is arranged outside the rotating shaft in a sleeving manner, and the rotating shaft and the second lead screw synchronously rotate through a synchronous block. The cleaning device has the advantages that the second lead screw nut pushes two connecting rods to approach each other, so that a plurality of cutting blades are expanded outwards relative to the rotating shaft under the action of the connecting rods, cutting teeth contact with the inner wall of a petroleum transmission pipeline, wax precipitation is efficientlytreated, and the device can automatically adapt to petroleum transmission pipelines with different pipe diameters and is convenient to operate and high in cleaning efficiency.

Description

technical field [0001] The invention relates to the technical field of petroleum, in particular to a mechanical cleaning device for impurities on the inner wall of petroleum pipelines. Background technique [0002] Petroleum, also known as crude oil, is a viscous, dark brown (sometimes greenish) liquid. Petroleum is mainly used as fuel oil and gasoline, and fuel oil and gasoline constitute one of the most important primary energy sources in the world. Petroleum is also a raw material for many chemical industry products such as solvents, fertilizers, pesticides and plastics. [0003] During the transportation of oil, due to the flow of oil in the pipe, a certain thickness of paraffin, colloid, condensate, sand and other impurities are gradually deposited on the inner wall of the pipe, which is collectively called wax deposition. Paraffin wax has accumulated on the inner wall of the oil pipeline for a long time, which affects the transportation capacity of the oil pipeline. ...

AI Technical Summary

Problems solved by technology

Paraffin wax has accumulated on the inner wall of the oil pipeline for a long time, which affects the transportation capacity of the oil pipeline. When workers clean the paraffin wax, it is labor-intensive and inefficient, and the inner wall of the oil pipeline that has been used for a long time will be uneven, which increases the cleaning workers. difficulty
