Pre-clearing machine for corrosion protection of outer wall of oil pipe

Abstract

The invention discloses a pre-clearing machine for corrosion protection of an outer wall of an oil pipe, and relates to the technical field of pipe clearing. The machine comprises a base, wherein a clearing mechanism and a rack are fixedly mounted on the top surface of the base, a high-pressure air pump is fixedly connected to the side surface of the base, one end of an air outlet of the high-pressure air pump is matched with the clearing mechanism, a group of first electric push rods are fixedly connected to the top surface of the rack, pressing seats are fixedly connected to the lower ends of the group of first electric push rods, and a limiting driving roller is rotationally connected between the inner surfaces of the pressing seats through bearings. According the machine, through design of the clearing mechanism, the machine can quickly realize synchronous clearing of the inner and outer walls of a pipe in an automated manner, during clearing, cleared impurities can be automatically discharged through spiral structure design of a clearing brush, and through matching design of the high-pressure air pump, on one hand, cleared dust can be timely blown out of the surface of the pipe, and on the other hand, the self-clearing property of the clearing brush can be conveniently ensured.

Description

technical field [0001] The invention belongs to the technical field of pipe fitting cleaning, in particular to a pre-cleaning machine for anti-corrosion protection of the outer wall of oil pipes. Background technique [0002] Due to the corrosion and oxidation of various chemical substances such as oil and air, the service life of the oil discharge pipe is greatly shortened. In order to prolong the service life, anti-corrosion liquid must be applied to the inner and outer walls of the oil discharge pipe. The outer wall should be cleaned in time. If the inner and outer walls of the pipe fittings cannot be cleaned in advance, on the one hand, it will reduce the uniformity of the application of the anti-corrosion liquid, and on the other hand, it will also hinder the adhesion of the anti-corrosion liquid on the inner and outer walls of the pipe fittings. On the one hand, the pipe fitting cleaning device is inconvenient to clean and process pipe fittings with multiple thicknesse...
