An outer wall uniform coating device for oil pipe anticorrosion protection

Abstract

The invention discloses an outer wall uniform coating device for oil pipe anticorrosion protection, and relates to the technical field of oil pipe anticorrosion. The invention includes an electric slide assembly, the upper surface of the electric slide assembly is sequentially installed with a grinding assembly, a negative pressure dust collection assembly, a material spraying assembly, a wiping assembly and a drying assembly; the grinding assembly includes a grinding base; the grinding base One surface is fixedly installed with a grinding motor; one end of the output shaft of the grinding motor is fixedly connected to a driving roller; the side of the driving roller is connected to a rotating outer ring through a belt drive; the inner wall of the rotating outer ring is connected to the grinding base through a bearing; the rotating outer ring has a surface It is rotatably connected with the grinding base; two symmetrically distributed first fixed seats are fixedly connected to the side of the rotating outer ring. The invention solves the problems of poor coating effect and low coating efficiency in the existing oil pipe anticorrosion protection outer wall uniform coating device through the design of the grinding component, negative pressure dust suction component, spraying component, wiping component and drying component.

Description

technical field [0001] The invention belongs to the technical field of oil pipe anticorrosion, in particular to an outer wall uniform coating device for oil pipe anticorrosion protection. Background technique [0002] At present, with the increase of oilfield production time in my country, the quality of injection water is deteriorating, and sulfate redox bacteria are gradually increasing. The serious corrosion and scaling of oilfield downhole pipe strings caused by this have become "persistent problems" that plague injection wells. The survey of my country's Zhongyuan and Shengli Oilfields found that the direct economic losses of these two oilfields due to corrosion of pipe strings and pipeline material costs reached 140 million yuan and 300 million yuan respectively; the replacement of pipe strings and pipelines affected production, resulting in indirect economic losses up to about 1 billion yuan. Corrosion and scaling symptoms are not eliminated, not only it is difficult ...
