ABSTRACT:
Powder collectors for the automatic collection and recycling of powders such as in a powder coating booth are disclosed. The collectors utilize a rollaway collection assembly having one or more cartridge filters therein so as to allow the quick change of vector assemblies on the coating booth for color change convenience. The cartridges themselves may also be readily changed as they preferably are not rigidly mounted to the collection assembly but instead merely sole positioned therein as to become functional upon turning on the air flow for the collection system. Continuous operation is provided by periodic blow-down of the cartridges with a fluidized bed providing automatic recycling (or disposal in the case of dust collection systems) of the collected powder. Various embodiments are disclosed including one embodiment utilizing envelope filters with an automatic blow-down provision.
