Abstract
Powder is sprayed uniformly and favorably from a powder nozzle into processing target air. In a coating mist collection apparatus, coating mist in processing target gas is collected by filters in a state in which a coating mist trapping filter covering layer made up of an accumulated layer of powder is formed on the surface of the filters. The coating mist collection apparatus is provided with a powder dispersion means that obtains a uniform powder concentration in the air in sealed powder tanks by dispersing the powder stored in the tanks in a uniform floating dispersed state, and is provided with a spray air conveying means that supplies the powder in the floating dispersed state in the powder tanks along with carrier air to powder nozzles through powder supply passages.
Claims14
A coating mist collection apparatus comprising:
- a filter that collects coating mist contained in processing target air discharged from a coating chamber;
- and
- a powder nozzle that is arranged in an air guiding passage that guides processing target air to the filter, and sprays powder into the processing target air passing through the air guiding passage,
- due to the processing target air, wherein the powder sprayed by, the powder nozzle is contained in a dispersed state, being passed through the filter, the coating mist in the processing target gas being collected by the filter in a state wherein a coating mist trapping filter covering layer made up of an accumulated powder layer is formed on a surface of the filter,
- wherein a powder dispersion apparatus is provided for obtaining a uniform powder concentration in air in a sealed powder tank by dispersing powder stored in the tank in a uniform floating dispersed state, and
- an ejector is provided for supplying the powder in the floating dispersed state in the powder tank along with carrier air to the powder nozzle through a powder supply passage in parallel with the uniformization of the powder concentration by the powder dispersion apparatus.
