  The stirring unit 4 shown in FIG. 15A has the same configuration as that of the stirring unit 4 shown in FIG. 13A except that the jet direction of warm air from the stirring blade shaft 42 is different.

  That is, the stirring blade shaft 42 is installed at the first location on the side surface of the rotating drum 41. Next, a second interval at a constant interval, for example, as shown in FIG. 15 (a), a constant interval is provided in the direction of the rotation axis of the rotary drum 41 from the first installation position.

The number of the stirring blade shafts 42 is appropriately set according to the scale of the processing tank 2. As shown in FIG. 15C, the stirring blade shaft 42 includes a stirring blade 46 on the side surface on the rotational direction side. On the other hand, as shown in FIG. 15 (d), a plurality of hot air ejection holes are appropriately formed on the side surface opposite to the rotation direction of the stirring blade shaft 42, so that the hot air is rotated around the stirring blade shaft 42. It ejects in the opposite direction (black triangle arrow direction) to the moving direction (thin arrow direction).

  On the side surface in the rotational direction of the stirring blade shaft 42 of the organic waste treatment apparatus 1 described above, as in the stirring blade shaft 42 illustrated in FIGS. It is good to provide. According to such a configuration, even if the particle size of the fluidized bed 5 is smaller than the diameter of the hot air ejection hole of the stirring blade shaft 42, the hot air ejection hole is effectively blocked by the external pressure of the fluidized bed 5. Is prevented. Further, the provision of the blockage prevention member increases the contact efficiency of the hot air blowing member with the fluidized bed, and when the warm air is supplied from the stirring blade shaft 42 to the fluidized bed 5, the heat source that emits the warm air is used. The transfer efficiency of heat energy to the fluidized bed 5 is improved.

  For example, the organic waste treatment apparatus 1 shown in FIG. 16 includes a blockage prevention plate 48 as a blockage prevention member for the hot air blowing hole of the stirring blade shaft 42. The blocking prevention plate 48 is made of the same material as the stirring blade shaft 42 and is formed in a plate shape as illustrated in FIGS. 16 (a) and 16 (b). The length in the width direction is set to be longer than at least the outer diameter of the stirring blade shaft 42 as shown in FIG. The blocking prevention plate 48 is fixed to the surface of the stirring blade shaft 42, that is, the piping 421 in the rotational direction so as to be disposed between the stirring blade 46 and the check valve 47. The blocking prevention plate 48 may be fixed by bolts or welding.

  An operation example of the organic waste treatment apparatus 1 shown in FIG. 16 will be described.

  Organic waste is introduced into the treatment tank 2 from the inlet 21. The fluidized bed 5 in the treatment tank 2 is filled lower than the rotating drum 41. The organic waste is charged manually or automatically by a pump. The organic waste in the treatment tank 2 and the fluidized bed 5 are stirred and mixed by the stirring blade shaft 42 and the stirring blade 46 that are rotated by the rotating drum 41. The stirring blade shaft 42 can introduce hot air (thermal energy) provided from the hot air supply unit 3 while being immersed in the fluidized bed 5. That is, while the stirring blade shaft 42 is immersed in the fluidized bed 5, the check valve 47 is positioned below the rotary drum 41 and the check valve 47 is in an open state. Can be introduced. In this way, the fluidized bed 5 is heated by the hot air supplied only by the stirring blade shaft 42 located below the rotary drum 41. Further, since the particles in the fluidized bed 5 flow while bypassing the blockage prevention plate 48 as the stirring blade shaft 42 rotates, blockage of the hot air ejection holes 422 by the fluidized bed 5 is effectively avoided.

  The water of the manure introduced is temporarily held in the fluidized bed 5 and gradually evaporated by the warm air supplied from the heated fluidized bed 5 and the stirring blade shaft 42. At this time, the rotation speed of the motor 44 that rotates the rotating drum 41 is controlled by the control unit 43 until the rotation of the rotating drum 41 is continued and the organic waste is evenly distributed in the fluidized bed 5. . In addition, organic components in the organic waste are aerobically biodegraded to carbon dioxide and water by the microorganisms contained in the organic waste and the microorganisms inhabiting the fluidized bed 5. As a result, the organic waste that has been initially charged is reduced by biodegradation and moisture evaporation, and the organic waste can be restarted. The organic waste can be continuously charged while controlling the amount of the organic waste charged when the biodegradation rate of the organic component and the rate of weight loss due to evaporation of water are clear.

  According to the organic waste treatment apparatus 1 described above, the check valve 47 that connects the rotating drum 41 through which the hot air is circulated and the stirring blade shaft 42 that ejects the hot air is positioned below the rotating drum 41. Since it is in the open state when it is, it is in the closed state when it is located above the rotating drum 41, so that the warm air can be supplied only to the fluidized bed 5 located below the rotating drum 41. Thus, since warm air is supplied only to the fluidized bed 5, the transfer efficiency of the thermal energy from the warm air supply part 5 which supplies the said warm air to the fluidized bed 5 improves.

  In particular, the stirring blade shaft 42 is moved by the rotation of the rotating drum 41 because the hot air blowing hole 422 that blows warm air from the hot air blowing hole 422 formed on the side surface other than the rotating direction. Thus, the hot air can be evenly supplied to the fluidized bed 5 without the hot air ejection holes 422 being blocked.

  In addition, a plurality of stirring blade shafts 42 are provided at regular intervals on the side surface of the rotating drum 41, so that warm air is supplied more evenly to the fluidized bed 5. In particular, the stirring blade shaft 42 is installed so that the first installation location of the rotary drum 41 and the second and subsequent installation positions are shifted by the same angle, 90 degrees left and right or 180 degrees, so that the fluidized bed 5 Is difficult to rotate with the plurality of stirring blade shafts 42 and the stirring blades 46 installed on the rotary drum 41, so that the fluidized bed 5 can be uniformly stirred.

  Furthermore, by providing the stirring blade shaft 42 with the stirring blade 46, the fluidized bed 5 can be stirred more uniformly.

  Since the conventional organic waste decomposition treatment apparatus is supposed to treat manure using sawdust as a fluidized bed, the structure of the stirring unit for stirring the fluidized bed is complicated. Therefore, when wood chips of various shapes that can be expected to decompose organic substances due to the effect of aerobic microorganisms are used in the fluidized bed, the wood chips may cling to the stirring unit and reduce the stirring effect.

  Since the structure provided with the stirring blade 46 formed in a plate shape in the vicinity of the tip of the stirring blade shaft 42 described in the embodiment is not a complicated structure, the occurrence rate of defects such as failure is reduced. Further, the entanglement of particles constituting the fluidized bed 5 on the stirring blade 46 is reduced.

  Then, the fluidized bed is blocked by providing a blocking member for the hot air blowing hole on the surface in the rotational direction of the stirring blade shaft 42 as in the organic waste decomposition treatment apparatus shown in FIGS. Since the fluid flows while bypassing the prevention member, the hot air blowing hole is prevented from being blocked by the fluidized bed.
