Abstract:
1. An underwater cutting and pelletizing apparatus, comprising: a cutting device with a water chamber having a cutter, wherein the cutting device cuts molten resin extruded from a die into pellets, the molten resin being carried by carrier water in the water chamber; a separation device that separates, from the carrier water, the pellets sent from the water chamber of said cutting device to downstream with carrier water, said separation device being disposed at a location higher than said cutting device; a tank that is disposed below said separation device and stores carrier water discharged from said separation device; a circulation path formed so as to circulate carrier water between said tank and the water chamber, the circulation path including a pipe standing upwards from the water chamber; and an electric power generator comprising a thermoelectric power generator that performs electric power generation based on a quantity of heat possessed by carrier water that is in said circulation path, wherein said thermoelectric power generator comprises a thermoelectric element that is mounted at an outer circumferential surface of the standing upward pipe adjacent to the water chamber, such that the heat absorbed from the molten resin in the water chamber is utilized in electric power generation to the fullest.
