Description

TECHNICAL FIELD

[0001] The utility model belongs to electrostatic powder spraying technical field, especially a kind of electrostatic powder spraying device. BACKGROUND

[0002] Traditional liquid spraying is gradually eliminated due to its serious environmental pollution, and electrostatic powder spraying is widely concerned due to its high efficiency and environmental protection. However, the existing electrostatic powder spraying equipment still has some deficiencies, which limits its wider popularization and use. At present, the common electrostatic powder spraying methods on the market mainly include high-pressure spray gun method and friction charging method. The high-pressure spray gun method generates an electrostatic field by applying high voltage to the spray gun, so that the powder is charged and attracted to the surface of the object to be sprayed. The friction charging method makes the powder collide with the pipe wall during powder conveying to obtain charge. These two methods have advantages and disadvantages. The former has a faster spraying speed but is prone to powder scattering and waste. The latter can reduce dust flying but requires high precision equipment and is relatively expensive. In summary, although various electrostatic powder spraying technologies and related products have been introduced on the market, there are still many challenges in practical application. On the one hand, the high-pressure spray gun method uses high working voltage, which has certain hidden dangers in safety and stability. On the other hand, although the friction charging method can reduce energy consumption to a certain extent, it relies on precise mechanical structures to charge the powder, which increases maintenance difficulty and production cost of enterprises, and is not conducive to achieving environmental protection goals.
