Description

Pipeline inner wall maintenance machine with cleaning and paint spraying functions

Technical Field

The invention relates to the technical field of short pipe inner wall cleaning and paint spraying, in particular to a pipeline inner wall maintenance machine with cleaning and paint spraying functions.

Background

A pipeline is a device for transporting a gas, liquid or fluid with solid particles, connected by pipes, pipe couplings, valves, etc. Generally, a fluid is pressurized by a blower, a compressor, a pump, a boiler, etc., and then flows from a high pressure portion to a low pressure portion of a pipe, or is transported by the pressure or gravity of the fluid itself. The use of pipelines is very widespread, mainly in water supply, drainage, heating, gas supply, long-distance oil and gas delivery, agricultural irrigation, hydraulic engineering and various industrial installations.

Pipelines for conveying oil and gas are mostly in a complex soil environment, and conveyed media are also corrosive, so that the inner wall and the outer wall of the pipeline can be corroded. Once the pipeline is corroded and perforated, oil and gas are lost, which not only interrupts transportation, but also pollutes the environment and even can cause fire hazard and causes harm.

Therefore, the prevention of corrosion of pipelines is an important part of pipeline engineering. Corrosion prevention (corrosion prevention of pipes) refers to measures for slowing down or preventing pipes from being eroded and deteriorated under the chemical and electrochemical action of internal and external media or by the metabolic activity of microorganisms. Description of corrosion phenomena of pipes corrosion is understood to be a chemical reaction of the material in the environment in which it is located, which reaction can cause loss of pipe material and lead to failure of the pipe components and even the entire pipe system.

In a pipeline system, corrosion is defined as: depending on the particular pipeline environment, chemical reactions, electrochemical reactions, and microbial attack that occur in all metallic and non-metallic materials of the pipeline system can lead to damage and loss of pipeline structure and other materials. In addition to direct damage to the material from corrosion, pipe damage caused by corrosion products can also be considered corrosion damage.

The common way of preventing corrosion of pipelines is coating corrosion prevention, namely, coating is uniformly and compactly coated on the surface of a metal pipeline subjected to rust removal to isolate the metal pipeline from various corrosive media, namely, the pipeline is painted.

The traditional short pipes of the inventor need to be maintained in a pipeline, different anticorrosive paints need to be applied to the inner wall and the outer wall, and therefore dip-dyeing type painting cannot be adopted; and because this batch of nozzle stub has some attachments because of using, if directly paint, the anticorrosive effect that plays the reality is not good, so need carry out the processing after cleaning to the inner wall. The conventional method is to clean the inner wall of the pipeline by using a cleaning device and then paint the inner wall by using a spraying device, namely two independent devices are needed, and the operation is troublesome under the condition of more short pipes.

Therefore, the inventor designs a pipeline inner wall maintenance machine with cleaning and paint spraying functions, aiming at the short pipe, and solving the problems.
