摘要

An improved device 0) for continuous electrostatic depoaition of powder paint over an article to bo powder coated cowprieing • closed chamber (2) having «t its upper level a motor driven conveyour (4) forming a loop (5) for carrying the articlaa to be powder coated, the powder coating aodule (8) ie provided at the centre of the said loop (5). the aaid nodule (B) comprising * hopper 19) for holding powder paint (10), a turbine diac assembly (1'1 ) provided at the lower end of a vertical shaft (20), The said vertical sh"ft passing through «n insulated tubular housing {2)t the upper end of the said vertical shaft being connected to a aator, a delivery tube (t2) being connected to the aaid hopper through a Metering and powder feeding device (13). The other end of the said delivery tube being connected to the aaid turbine disc (11) assembly, the said turbine diac assembly comprising a lower disc (22) and «n upper disc (24) acting aa a cover the said lower diac having upwarily Planting outer surface, with plurality of iauvred fina (23). An electrode plate (15) being fitted at the lower end of the said insulated tubular housing (21) just above tha said turbine diac assembly (11), the aaid electrode plate (15) being connected to a high voltage generator (14*) with the help of high tension coble (17), a reciprocating mechanism worked by motor (19) being provided at the upper and of the chamber far upward and downward movement of the said electrode plate (15) along with the said tubbl»r housing and the aaid turbine disc {11).
