Abstract
1426517 Fluidised coating apparatus ELECTROSTATIC EQUIPMENT CORP 16 May 1973 [18 May 1972] 23336/73 Heading B2L Articles 116 to be coated with powder are moved through a channel 86 by means of an overhead conveyor and receive the powder material from electrostatic fluidised beds being separated from the channel by means of walls 58 which act as weirs or baffles to control the flow of coating powder to the articles. The fluidised beds have plenum chambers 36 with porous plates 48 thereabove. The plates 48 incorporate electrostatic grids 52 which change the fluidised powder material relative to the articles on the conveyor which are normally earthed. The baffles 58 as shown are inside the booth and are downwardly inclined in the direction of conveyor movement so that progressively more of the article is exposed to the conveyor. A third fluidised bed may be provided at the end of the booth directly below the line of travel of the articles. This bed is independant of the other two and operates at a lower voltage to coat the bottom of the articles. Powder may be fed in through pipes 73 and excess powder collected in hoppers 74 below the passageway 86. Instead of being inclined, the baffle may be slotted to act as a mask or the baffle may be horizontal with the conveyor inclined.
