Abstract
The present invention provides an air-wash powder sieving apparatus for a powder coating system having a powder spray gun, a powder suction pump assembly, and a powder container/hopper. The said sieving apparatus includes a housing, a sieving section and at least one air jet section adapted within the housing, for directing compressed air on the sieve. The compressed air impinged by the air jets onto the sieving mesh not only skims and washes the sieving mesh and keeps it de-clogged but also acts as a secondary air of the powder suction pump.
Claims5
An air-wash powder sieving apparatus for a powder coating system having a powder spray gun, a powder suction pump assembly, and a powder container/hopper, said sieving apparatus comprising:
- a housing for connecting to a suction side of the powder suction pump assembly;
- a sieving section within the housing, said sieving section having at least one sieve mesh through which powder is forced by a suction action generated by a powder suction pump of the suction pump assembly;
- and
- an air-jet section having one or more air-jet orifices and an inlet for providing compressed air to the air-jet orifice(s) of the air-jet section wherein the air-jet section is configured in such a way that the compressed air from the air-jet orifice(s) skim and wash the sieve to prevent clogging and ensure continuous flow of freshly sieved smooth flowing powder through the powder coating system.
