Electrostatic generator external type pipeline anticorrosion spraying device

Abstract

The invention discloses an electrostatic generator external type pipeline anticorrosion spraying device. The electrostatic generator external type pipeline anticorrosion spraying device solves the problems that existing electrostatic spray guns are inconvenient to use and poor in use safety. A fluidization control module inside a control cabinet comprises a fluidization controller and a fluidization electromagnetic valve; a valve control of the fluidization electromagnetic valve is connected between a gas source and a fluidization gas pipe; the fluidization gas pipe communicates with the bottom of a powder fluidization tank; an electrostatic control module comprises an electrostatic controller and a powder feeding electromagnetic valve; a valve control of the powder feeding electromagneticvalve is connected between the gas source and a powder feeding gas pipe; the powder feeding gas pipe communicates with the gas input end of a powder pump; a high-frequency boost module comprises a high-frequency booster; a powder cavity formed in a spray gun body communicates with the powder output end of the powder pump; a nozzle is installed on the gun body and communicates with the other end of the powder cavity; and a polarized electrode is arranged on the nozzle and is electrically connected with the high-frequency booster. The spraying efficiency is high, use is convenient and safety ishigh.

Description

technical field [0001] The invention relates to an electrostatic spraying device, in particular to a pipeline anticorrosion spraying device with an external electrostatic generator. Background technique [0002] As we all know, people cover the inner and outer surfaces of steel pipes with epoxy materials to make them have strong anti-corrosion performance. At present, the common covering method of epoxy materials is to heat the workpiece to a certain temperature first, and then use a spray gun to evenly spray epoxy powder on the workpiece, and the epoxy powder will solidify after being melted by heat to form a layer of high molecular weight cross-linked structural coating. . Due to the limited operating space for covering the inner surface of the steel pipe with epoxy material, workers can only extend the spray gun into the steel pipe, and control the uniformity of the epoxy powder on the inner surface of the steel pipe by artificially controlling the speed and angle of the...
