Field of the Invention The present invention relates to an oiling device for a mixture of foamed resin and expanded polystyrene, and more particularly to a safe oiling device. So-called foamed resins such as foamed resin and styrofoam are discarded after being used as buffers, fish boxes, food trays, etc. However, since the volume of dust is large, the cost required for collection and transportation is large. Also,
Since it is difficult to secure a garbage disposal site, it is becoming difficult to reclaim it as it is. Moreover, it is generally difficult to install waste treatment facilities in urban areas due to rising land prices and opposition from residents, and it is unavoidable to install waste treatment facilities in suburbs far from the place where waste is generated. There is no situation. In this way, the invention of the device that oilizes the foamed resin, etc., which is discarded in large quantities on a daily basis, at low cost, efficiently and safely, and reuses it as a fuel is difficult to secure a garbage disposal site, preventing environmental pollution, and reusing energy resources. It is strongly desired from the viewpoints such as.

The foamed resin or the like that has entered the weighing hopper 82 is weighed together with the weighing hopper 82 by the load cell 85. It is supplied to the screw transfer device 1 through the input hopper 7. The foamed resin and the like that have entered the screw transport device 1 are heated by the heater 3 while being transported, and thus are gradually dissolved into a solution and then transported into the thermal decomposition furnace 11 through the carry-in port 25 of the thermal decomposition furnace 11.

The flow rate of the liquefied oil-gas liquid is measured by the flowmeter 80 on the way. In the oil-water separator 40, the oil and the water are separated due to the difference in specific gravity, and the oil is collected in the produced oil tank 43 through the produced oil pipe 42. On the other hand, water is discharged through the valve 44.

The component that does not undergo thermal decomposition contained in the solid component is generated as a solid residue, but if this amount becomes large, the stirring performance of the stirring device 14 will be impaired, so it is necessary to remove the residue. When the residue is taken out, the residue valve 29 is opened and the stirring device 14 is rotated. For the residue, the inclination of the bottom plate 27, the stirring plate 16 and the stirring small plate 1 are used.
The rotation of 7 causes the residue to pass through the residue outlet 28, the residue valve 29, and the residue port 47 and drop to the residue receiver 46 of the residue box 45. When the residue is taken out or when starting again after taking out the residue, the nitrogen valve 52 is opened and the nitrogen gas is blown into the residue box 45 or the thermal decomposition furnace 11 to blow the air inside the residue box 45 or the thermal decomposition furnace 11. Prevent fire by flushing and replacing with nitrogen gas. The expelled air is guided to the flare stack 56 and burns as the propane gas burns. The pyrolysis furnace 11, the residue box 45, and the like are installed in the fire protection chamber 70.
Since the exhaust device 77 is attached, the fire protection chamber 7
The air in 0 is always ventilated. Further, the temperature sensor detects an increase in temperature inside the fire protection chamber, the gas detector detects a combustible gas inside the fire protection chamber, and the fire protection damper 72.
When the temperature of the air flowing to the temperature exceeds a predetermined temperature and the temperature fuse operates, the fire damper 72 automatically closes. Further, by opening the nitrogen valve 52, nitrogen is blown into the fire protection chamber 70 to stop the apparatus in an emergency.

とが可能となった。According to the present invention, by providing the function of blowing nitrogen gas into the residue box 45 and the pyrolysis furnace 11 and providing the safety valve 55 for keeping the pressure of the pyrolysis furnace 11 below a predetermined pressure,
It was possible to provide a safe oiling device for foamed resin or the like that does not cause environmental pollution. Further, according to the present invention, a function of blowing nitrogen gas into the residue box 45 or the thermal decomposition furnace 11 is provided,
To blow out nitrogen gas into the residue box 45 or the thermal decomposition furnace 11 when the residue is taken out of the thermal decomposition furnace 11 and when it is subsequently started to replace the nitrogen gas with the nitrogen gas to prevent a fire. I was able to. In addition, according to the present invention, the pyrolysis furnace 11, the residue box 45, and the like are installed in the fire protection chamber 70.
Since the structure is such that the air inside the fire protection chamber 70 is ventilated by the exhaust device 77, it is possible to provide a safe oiling device for foamed resin or the like. In addition, according to the present invention, the safety of the entire apparatus is improved because nitrogen gas is blown into the fire chamber 70 by the operation of the fire damper 72 or the detection of the temperature sensor or the gas detector to stop the apparatus in an emergency.
If there is no conventional fire protection chamber, the pyrolysis furnace 11
When removing the residue from the furnace, it was necessary to blow nitrogen gas into the pyrolysis furnace 11 and the residue box 45, and then wait until the temperature in the pyrolysis furnace 11 fell to room temperature. Since the installation safety has been improved, the pyrolysis furnace 1
It was possible to take out the residue from the thermal decomposition furnace 11 to the residue box 45 immediately after blowing the nitrogen gas without waiting for the temperature inside 1 to drop.
