VIBRATING DEVICE FOR DRY REGENERATION OF THE MOULDING SAND

摘要

1. Vibrating device for dry regeneration of moulding mass is comprised of an oblong symmetric container, resting on spring elements and started up by means of a vibrator, fixed to a flat bottom of the container and equipped with a strip screen placed in the top part of the container and crushing-grinding elements filling the bottom part of the container and holes at the sides, characterised in that the working surface of the screen (4) lowers towards the middle, thus creating a oblong pit, the axis of which is parallel to the axis of rotation of the vibrator (3). The same number of channels (7) go out from the parallel to the vibrator axis (3) side walls of the container (1), equipped with gutters (9), fixed in by means of mechanical bolts (8), and arranged in series inertial crumbling-grinding elements (13). The inside of the container (1) is separated from the channel (7) inlets by means of partitions (11), mounted in the notches (10), located in the side walls of the bottom of container (1).IMAGE
