Powder spraying equipment for pressure type nonpolar lamp

Abstract

The invention provides powder spraying equipment for a pressure type nonpolar lamp, which comprises a powder spraying chamber, a power spraying tube, a sealing plate, a recoverer and a recovering tube; an upper mouth of the powder spraying chamber is provided with the sealing plate; the cahmber wall of the powder spraying chamber is provided with an air inlet; the bottom of the recoverer is arranged on the sealing plate; an upper mouth of the recoverer is open; the sealing plate is provided with a powder spraying port and a recovering port; the powder spraying tube runs through the powder spraying port; the lower end of the powder spraying tube extends to the inside of the powder spraying chamber; the upper end of the power spraying tube extends to the inside of a nonpolar bulb body on the upper part of the recoverer; the recovering tube runs through the recovering port; the upper end of the recovering pipe is leveled with the upper surface of the sealing plate; and the lower end of the recovering tube extends the inside of the powder spraying chamber. The power spraying equipment can avoid the hand-shaking type power spraying, accelerates the power spraying speed of a product and has even powder spraying; and sprayed powdery slurry can be recovered to a powdery slurry tank for secondary spraying.

Description

technical field

[0001] The invention relates to a powder spraying device, in particular to a pressure type electrodeless lamp powder spraying device. Background technique

[0002] At present, in the electrodeless lamp industry, the general method of powder coating is to pour the powder into the bubble body and shake it around the bubble body by hand. This method is not only time-consuming and manpower-consuming, but also not environmentally friendly and wasteful. Moreover, the light bulb powder enamelled is uneven, and there are obvious traces of powder accumulation.

[0003] Powder spraying equipment is used in the production of existing energy-saving lamps, but the bulbs of energy-saving lamps are small in size, and the requirements for powder spraying technology are relatively low, while the inside of the bubble body of electrodeless lamps is very large and wide, and the speed and size of powder slurry spraying are required. Relatively high, so the powder spraying equipm...
