SOLIDIFICATION PROCESSING METHOD AND SOLIDIFICATION PROCESSING APPARATUS

摘要

FOR MANUFACTURE OF SOLID FUELS BY SOLIDIFYING PROCESSING-OBJECT MATERIALS CONTAINING PLASTICS, WASTE PAPER AND WASTE WOOD, THE PROCESSING-OBJECT MATERIALS INPUTTED THROUGH AN INPUT PORT 12 ARE SUBJECTED TO WATER INJECTION SO THAT THEIR WATER CONTENT BECOMES 15 WT% OR MORE, PREFERABLY 20 WT% OR MORE, AND THEN KNEADED, COMPACTED AND EXTRUDED IN THREE TURNS OR LESS, BEING EXTRUDED FROM MOLDING NOZZLES 53 OF AN END FACE PLATE 5. THE WATER INJECTION IS PERFORMED BY A WATER INJECTION NOZZLE 31 FROM THE INPUT PORT 12 INTO A CASING 11. OPENING AND CLOSING OF A SOLENOID VALVE 33 INTERPOSED ON A WATER INJECTION PIPE 32 ADJOINING THE WATER INJECTION NOZZLE 31 IS CONTROLLED BASED ON A SIGNAL S1 DERIVED FROM A TEMPERATURE SENSOR 55 PROVIDED AT A MOLDING NOZZLE 53 OF THE END FACE PLATE. SUCH DISADVANTAGES AS INFLAMMATION DUE TO EXCESSIVELY HIGH TEMPERATURES OF THE PROCESSING-OBJECT MATERIALS OR WORSENED SHAPE RETENTION OF SOLIDIFIED MATERIALS DUE TO EXCESSIVELY LOW TEMPERATURES OF THE PROCESSING-OBJECT MATERIALS CAN BE PREVENTED.
