Description

Technical Field

[0001] The utility model relates to the technical field of thermal spraying equipment, in particular to a spraying device for a spiral rotor. Background Art

[0002] At present, the surface of the spiral rotor is processed to make it anti-wear and anti-corrosion, usually using the supersonic flame spraying process, which is a new type of thermal spraying technology developed in the early 1980s on the basis of ordinary flame spraying. It uses hydrogen, acetylene, propylene, kerosene, etc. as fuel, oxygen as a combustion aid, and burns in a combustion chamber or a special nozzle to produce a supersonic flame. At the same time, the powder is sent into the flame to produce molten or semi-molten particles, which collide at high speed and deposit on the surface of the substrate to form a coating.

[0003] The existing spraying device can only perform spraying operations at one angle. Since the surface of the spiral rotor is uneven, it is difficult to spray evenly on the inclined surfaces and gaps. Secondly, during use, a large amount of dust enters the displacement mechanism. Over time, a large amount of impurities will exist in the mechanism of the mobile spray gun, which is difficult to clean and may even affect the movement rate of the spray gun, resulting in a deterioration in the spraying effect.
