Abstract

Improvements introduced in the fusion tanks, characterized in that, being mainly intended to flow and refine thermoplastic material, it comprises a tank, batch feeding means to supply batches or batches to a tank upper part, and a bottom provided with means outlet for the molten and refined material, arranged on the underside of the tank, the outlet means being presented in the form of a conduit, in contact with a part of at least the upper surface of the tank bottom extending from the vicinity of the geometric center of the bottom to the outer surface of the tank side, not below the bottom surface of the tank bottom and having an inlet in the vicinity of said geometric center and an outlet in the lateral outer surface.
