LIQUEFYING APPARATUS

摘要

It is an object of the present invention to provide a conversion-to-oil apparatus capable of efficiently treating plastic. The conversion-to-oil apparatus comprises a melting unit 1 for heating and melting plastic fed thereto and a decomposing unit 2 for further heating and vaporization-decomposing the molten plastic melted by the melting unit 1, wherein the decomposing unit 2 is inclined upwardly, having a lead screw LS mounted therein, and is provided at its upper end portion with a catalyst cylinder 19 extending upwardly and a residue takeout unit R extending downwardly, and the decomposing unit 2 has a prevention means for preventing molten plastic gas from flowing down to the residue takeout unit R.
