<p>PURPOSE:To hold the waste plastics under reversing them in a hot stove and permit to drop the softened and molten waste plastics smoothly into a discharging port by a method wherein the waste plastics before softening and melting, which are received in the hot stove, are heated under floating and holding them by hot air so as not to be dropped through the discharging port. CONSTITUTION:A plurality of hot-air introducing pipes 13 are attached to the head 9a and neck 9b of the not stove 9 circumferentially and downwardly and hot air, sent into the hot stove 9, is blown up toward the upper part of the hot stove 9 as strong upward airflow. Accordingly, the block of thrown waste plastics 19 is heated under being rotated in a condition that the block is floated and held in the hot stove 9, thereafter, is soften, molten and condensed, thereby moving to the lower part of the center of the hot stove 9. The specific gravity of the block is increased and the plastics drop into a vessel 15 sequentially. In this case, unsoftened thermosetting plastics, stones, garbage or the like is dropped into the vessel 15 together with the softened and molten plastics smoothly since there is no obstacle in the part of discharging port.</p> |
