| 摘要 |
The present invention relates to a powder distributor for electrostatic painting provided with reciprocating vertical movement, wherein the powder in mixture with air reaches the center of a sectional element, for example a disk, which disperses it evenly over its perimetral rim. The distributor comprises a reservoir divided into two chambers by an intermediate porous septum, a first, upper chamber into which a first, powder-in-air suspension feed circuit debouches, and a second, lower chamber into which a second, compressed air feed conduit debouches. Provision can also be made for a third conduit, for compressed air feed, the compressed air being in such case discharged parallel to the direction of discharge of the powder suspension.
