Petroleum pipe cleaning device

Abstract

The invention discloses a petroleum pipe cleaning device, and belongs to the technical field of pipe cleaning. The device comprises a motor and a rotating rod, wherein one end of the rotating rod is connected with a rotor of the motor, and the other end of the rotating rod is connected with a cleaning structure; the cleaning structure comprises a cylinder, a push rod is arranged in the cylinder, discs are arranged on the push rod, and the push rod is used for driving the discs to move axially along the cylinder; and trapezoid blocks are arranged on the side wall of the cylinder and right facethe discs, the trapezoid blocks have narrow tops and wide bottoms, bodies of the trapezoid blocks penetrate through the side wall of the cylinder, the upper ends of the trapezoid blocks are hinged tothe cylinder, and cleaning heads are hinged to the sides, outside the cylinder, of the lower ends of the trapezoid blocks. According to the device, the trapezoidal blocks and the cleaning heads can betightly attached to the outer wall of the cylinder under the action of gravity, the device can be conveniently placed in a pipe, the push rod drives the discs to move downwards to extrude the trapezoidal blocks, the trapezoidal blocks can rotate, and then the cleaning heads are moved to be tightly attached to the pipe wall, so that the device is convenient to use and saves time.

Description

technical field [0001] The invention relates to the technical field of pipeline cleaning, in particular to an oil pipeline cleaning device. Background technique [0002] The pipeline is a kind of fluid conveying equipment. During actual operation, due to the corrosiveness of the fluid and the inclusion of impurities, the inner wall of the pipeline will gradually scale, resulting in an increase in the friction coefficient of the inner wall of the pipeline, a decrease in the flow channel area, and an increase in transportation consumption. Power, such as oil pipelines, will gradually deposit a certain thickness of paraffin, colloid, condensate, sand and other impurities on the inner wall of the pipeline, collectively known as 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. For large-scale equipment, it is usually cleaned by supporting cleaning balls and other equi...

Problems solved by technology

This device can clean pipes with various diameters and has high efficiency. However, in order to adapt to different pipe diameters, the cleaning block is compressed by a spring and then clings to the pipe wall. Therefore, when it is inserted into the pipe, it is necessary to manually compress the spring to assist each cleaning block to enter. The pipeline, especially when there are multiple cleaning blocks around the circumference, needs to compress the spring on each cleaning block at the same time before putting it into the pipeline, which is cumbersome and time-consuming
