【Example】

 Embodiments shown in the drawings will be described below. First, the entire conventional garbage processing machine will be described with reference to FIGS. The fermentor 2 is constructed by blow molding of synthetic resin, etc., and has an inlet 2a covered with the lid 3 at the upper end and a water outlet 2e also serving as a vent at the lower end. A lower net 4 is inserted into the inside of the fermentation tank 2 at the water outlet 2e. Further, upper left and right side surfaces have upper openings 2d at the recessed portions, and the upper openings 2d. A mesh plate 5 is attached to the. Further, bearing support openings 2b and 2c are formed in the central portions of the left and right side surfaces of the fermentation tank 2 so as to penetrate the rotary shaft 6 and to fix the bearing support portion of the rotary shaft 6.

A stirring device 7 is fixed to the rotating shaft 6, and the rotating shaft 6 does not rotate when the fermentation tank (2) is rotated by the rotating handle 8. Therefore, the stirring device 7 also rotates the fermentation tank 2. It is fixed at this time, and when the garbage is rotated by the rotation of the fermentation tank 2, it is caught by the stirring device 7 and stirred. A plurality of aeration pipes 1, 1, 1 are arranged below the stirring device 7 provided on the rotary shaft 6 and at a position where the contents are easily mixed and stirred when the fermentation tank 2 is rotated.

Next, when the lid 3 is closed, a lid bottom vent hole 3 b is opened at the bottom of the portion fitted into the insertion port 2 a and is covered with the upper net 9. The inside of the lid 3 is configured like a double container, the inside of the lid 3 communicates with the inside of the fermentation tank 2, and the air inside the fermentation tank 2 also passes through the bottom vent holes 3b of the lid. It is possible to pass through the inside of the lid 3 and to be exposed to the atmosphere from the opening 3a of the lid. The lid 3 is pivotally pinned by the lid pivotal support 2f of the fermentor, and pivots to the open and closed states with the lid pivotal support 2f as a fulcrum, and in the closed state, the fermenter is hooked with the hook 10. The fixing member 11 attached to 2 is locked and fixed.

Fermenter 2 is composed of semi-transparent synthetic resin, the amount of raw garbage can be judged from the outside, and if the amount is too large, the fermentation will not be promoted. It is set up. Next, the upper end of the rotary handle 8 is fixed to the sprocket shaft 12, and a chain 14 is wound around a sprocket 13 fixed to the sprocket shaft 12, and the chain 14 also supports the rotary shaft 6. It is wound around a sprocket 15 that also serves as a boss. Therefore, when the fixed sprockets 15 are rotated by the rotating handle 8 via the sprockets 13 and the chains 14, the fermentor 2 is decelerated and rotated around the rotating shaft 6 with a light force. Reference numeral 16 denotes a support stand attached to the shaft support 17.

According to the above, stirring fermentation is performed by the stirring device fixed to the main body by the rotation of the fermentation tank, and since the garbage is not circulated and stirred, the whole does not have a uniform water content. Since aerial fermentation is not performed uniformly, good fermentation cannot be performed. This plan is an improvement of the above points.

In FIG. 1, reference numeral 18 denotes an outer fermentation tank, and an inner fermentation tank 19 is arranged on the outer fermentation tank to form two inner and outer fermentation tanks. A spiral blade 20 is provided on the outer wall of the inner fermentation tank 19, and an air supply cylinder 21 covered with a non-woven fabric or the like is provided upright at the center of a bottom opening 22. At the bottom opening 22 of the air supply cylinder 21, there is a downward facing plate body 23, and a hollow box 24 is attached below this. As shown in FIG. 4, the dish 23 has a through hole 25 connected to the air supply cylinder 21, and the box 24 has a through hole 26 in the peripheral wall thereof. The protrusion 27a of the protrusion 27 provided on the bottom wall of the box 24 is fitted into the slot 29a of the receiver 29 attached to the shaft of the motor 28, and the inner fermentation tank 19 is rotated by the motor 28. The inner fermentation tank 19 can be freely attached to and detached from the motor shaft. The flap 23a of the dish 23 overlaps with the pot-shaped guide 18b of the bottom wall 18a of the outer fermentation tank 18.

At the center of the empty chamber 30 between the bottom wall 18a and the outer wall 18c of the outer fermentation tank 18, there is an outer wall 31a of the blower chamber 31 connected to the pot-shaped guide 18b. A blower fan 33 rotated by a motor 32 is provided in the blower chamber 31, and a vent hole 34 is provided in the outer wall 31a. To the right of the vacant room 30 is an air vent 35. A lid 36 having a double structure is pivotally supported 37 above the outer fermentation tank 18 and can be opened and closed. A sensor 38 is provided at the tip of the lid 36 so as to prevent the rotation of the inner fermentation tank 19 when the lid is opened. The outer lid 36a of the lid 36 has a control box for operating the motor. Further, a net body 40 with a deodorant is stretched on the inner lid 36b of the lid body 36. An exhaust chamber 41 is provided on the pivotal 37 side of the lid 36, an exhaust fan 43 driven by a motor 42 is provided inside, a through hole 44 is provided on the inner wall of the exhaust chamber 41, and an opening 45 is provided on the outer wall. . Others 46 are tires provided at the bottom of the outer fermentation tank 18, and 47 is a stand.

Now, the lid 36 is opened around the pivot 37, and the garbage is put into the inner fermentation tank 19. When the lid 36 is closed after insertion, it is detected that the sensor 38 is closed.Therefore, when the switch of the control box 39 is pressed, the motors 28, 32 and 42 are driven and the inner fermentation tank 19 is rotated. At the same time, the fan / motor cooling fan 33 and the exhaust fan 43 rotate. Therefore, the garbage introduced into the inner fermentation tank 19 is circulated and stirred by the spiral blade 20 from the inner fermentation tank 19 to the outer fermentation tank 18 and from the outer fermentation tank 18 to the inner fermentation tank 19. On the other hand, air is sucked in from the air port 35 by the air blower / motor cooling fan 33, passes through the vent hole 26 of the box 24, is sent to the air supply tube 21 through the vent hole 25 of the pan 23, and the inner lid 36b is closed. It is discharged from the deodorant-equipped net 40 to the outside by the exhaust fan 43. The deodorized moist air is discharged from the exhaust opening 45.

According to the present invention, the rotation of the inner fermentation tank 19 circulates and agitates the garbage in the spiral blade 20, so that the moisture content becomes uniform throughout, and the air passing through the motor 28 is blown by the air blower / motor cooling fan 33. Since it is heated by the heat of the motor and sent to the fermentation tank, aerobic fermentation is carried out uniformly. Further, since the air passing through the fermentation tank is deodorized by the deodorant-equipped net 40, the odor is not emitted to the outside. While the lid is open, the inner fermenter 19 does not rotate because it sends a signal to the control box 39 that the sensor 38 is open. Therefore, it is dangerous. Further, the inner fermentation tank can be taken out of the outer fermentation tank 18 with the garbage contained in the shaft of the motor 28, and the fermented product can be discharged. Since the air supply cylinder 21 is stretched with a non-woven fabric or the like, clogging is prevented. The structure for constructing the fermentation tank of the present invention into two tanks inside and outside is not limited to the one shown in the drawing.

[0015]

[Effect of device]

 In the case of this proposal, the spiral blade of the inner fermentation tank circulates and stirs the garbage, so that the whole has a uniform water content and the aerobic fermentation is carried out uniformly, so there is no odor and smell from the air sent from the air supply tube. Fermentation is obtained.
