Abstract

Pulversprühbeschichtungsvorrichtung mit mindestens einem Druckluftauslass (8), der an eine Druckluftquelle (14) angeschlossen ist, von welcher ihm Druckluft (15) mit solcher Menge und Druck zuführbar ist, dass die Druckluft am Druckluftauslass (8) die Pulverrandschicht vom Pulverkanal (4) abhebt, den Pulverstrom zum radialen Strömungszentrum hin zusammendrängt und verwirbelt, an einer nahe beim stromabwärtigen Ende (6) des Pulverkanals (4) gelegenen Stelle.

Figure 00000001
Powder spray coating device with at least one compressed air outlet (8), which is connected to a compressed air source (14) from which compressed air (15) can be fed with such quantity and pressure that the compressed air at the compressed air outlet (8) lifts the powder edge layer from the powder channel (4) , which compresses and swirls the powder flow toward the radial flow center, at a location near the downstream end (6) of the powder passage (4).
