发明名称 Feed apparatus and portable dust collector
摘要 A feed apparatus feed apparatus for delivering particulate material to a foundry furnace having disposed therein a furnace form defining an annulus with the furnace exterior wall for receipt of the particulate material. The novel feed apparatus broadly includes a cover, having a top end, side wall, and a bottom end, the latter of which is adapted to fit on top of the furnace ring or melt deck floor; a rotatable tabletop that is adapted to fit on the top end of the cover while permitting air ingress into the cover and having at least one access port for delivering the particulate material into the interior of the cover; a form top that is adapted to fit within the cover on top of the furnace form to facilitate delivery of said particulate material into the annulus made by the furnace form and the furnace exterior wall; means for rotating the tabletop about the centerline of the cover; and means for centering the tabletop as it rotates about the centerline of the cover.
