METHOD FOR PRODUCING SOLID FUEL AND APPARATUS

摘要

PROBLEM TO BE SOLVED: To convert waste plastics and papers with garbage sticking thereto into an RPF (refuse paper and plastic fuel). SOLUTION: A garbage separating apparatus 30 is provided on the downstream side of a feeding part 29 for railroad refuse separated combustibles 28 prepared by separating cans, bottles and PET bottles 27 from railroad refuse 26 and RPF production equipment 31 is installed on the downstream side thereof. The garbage separating apparatus 30 is equipped with a separation tank formed into a horizontal cylindrical state and having a sieve surface in the lower half part and is composed of a plurality of hammers with tips having a length and dimension reaching the position near the inner peripheral surface of the separation tank and mounted in a rotating shaft in the axial center part of the separation tank so as to shake in the rotative direction. The railroad refuse separated combustibles 28 are struck by the hammers rotating in the separation tank of the garbage separating apparatus 30 to separate the garbage 34 sticking thereto. The separated garbage 34 is pressed against the sieve surface with the tips of the hammers, passed through the sieve surface and removed. The railroad refuse separated combustibles 28 after separating and removing the garbage 34 are then fed to the RPF production equipment 31 to produce the RPF 35. COPYRIGHT: (C)2007,JPO&INPIT
