NOVELTY - Sealing apparatus comprises a waste organic matter decomposition device comprising a heating chamber (110) for heating by using a heater as heating source (111), a first transfer pipe (120) whose one end is inserted into heating chamber and other end is exposed to outside and capable of transferring crushed organic matter from a crushed organic matter supply unit via an inlet port, a first auger means (122) which transfers crushed organic matter by rotation driven by a drive unit equipped in the inner portion of first transfer pipe, and a second transfer pipe inserted into heating chamber.    USE - The apparatus is useful for blocking carbon in air inflow of pyrolyzing furnace (claimed).    ADVANTAGE - The apparatus completely blocks the external air flow and improves the durability of the pyrolyzing furnace and ensures continuous operation.    DETAILED DESCRIPTION - Sealing apparatus comprises a waste organic matter decomposition device comprising a heating chamber (110) for heating by using a heater as heating source (111), a first transfer pipe (120) whose one end is inserted into the heating chamber and the other end is exposed to the outside and capable of transferring the crushed organic matter from a crushed organic matter supply unit via an inlet port, a first auger means (122) which transfers the crushed organic matter by rotation driven by a drive unit equipped in the inner portion of the first transfer pipe, a second transfer pipe whose one end is inserted into the heating chamber and the other end is exposed to the outside and installed at the bottom side of a connecting tube and connected with the first transfer pipe via the connecting tube and capable of discharging the organic matter supplied from the first auger means via an exit hole of carbon collecting-transferring pipe (124), a second auger means capable of transferring the organic matter towards the exit hole by rotation driven by a drive unit equipped in the inner portion of the second transfer pipe, a third transfer pipe capable of easily discharging the vapor and inserted and connected with a third auger means, a vapor discharge tube installed on one side of the first transfer tube top surface and connected with the other end of the third transfer pipe, and a condenser means capable of producing oil from the vapor supplied by the third transfer pipe. The carbon collecting-transferring pipe is provided with a carbon transferring auger to transfer carbon by rotation driven by a driving motor. The apparatus further includes a coolant passage equipped with a cooling water inlet to cool the high-temperature carbon in the discharging pipe, and first and second flap damper valves connected in series which discharge or block carbon via the carbon exhaust hoses. The lower part of the second flap damper valve is connected with an air inflow sealing device provided with inflow sealing body part formed with multiple barrier wall portions, which are rotated by a driving shaft.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the separation system of oil vapor and solid components of organic waste thermal decomposition device equipped with apparatus for blocking carbon in air inflow of pyrolyzing furnace.
