Title (EN) POWDER HOPPER WITH QUIET ZONE, A COMBINATION OF A POWDER HOPPER AND A POWDER SPRAY GUN AND A METHOD OF OPERATING A POWDER HOPPER
(FR) TRÉMIE À POUDRE AVEC ZONE CALME, COMBINAISON DE TRÉMIE À POUDRE ET DE PISTOLET PULVÉRISATEUR DE POUDRE ET PROCÉDÉ D'EXPLOITATION DE TRÉMIE À POUDRE
Abstract:
(EN) A powder hopper is provided with a low turbulence zone for supplying powder to a spray gun. The low turbulence zone is defined by a baffle inside the hopper with the low turbulence zone being within a volume of the baffle, and an annular zone between the baffle and the hopper is used to bulk feed powder into the hopper. The low turbulence zone may alternatively be in the annular zone with powder added to the volume of the baffle. One preferred application for this hopper is in connection with the use of fine powder coating materials to coat the interior of small diameter cans.
(FR) L'invention concerne une trémie à poudre comportant une zone de faibles turbulences afin d'alimenter en poudre un pistolet de pulvérisation. La zone de faibles turbulences est définie par une chicane dans la trémie, la zone de faibles turbulences se situant dans un volume de la chicane, et une zone annulaire entre la chicane et trémie est utilisée for compacter la poudre dans la trémie. La zone de faibles turbulences peut encore se situer dans la zone annulaire, de la poudre étant ajoutée au volume de la chicane. Une application préférée de cette trémie est liée à l'utilisation de matériaux de revêtement en poudre fine afin de revêtir l'intérieur de boîtes de diamètre réduit.
