A method of fermenting organic waste by supplying air and supplying oxygen has been proposed, and various methods of treating waste with aerobic microorganisms using a bacterial bed are known.

[0003] However, in the case of using a screw conveyor as the stirring means as described above, only the garbage and the bacteria bed around the screw conveyor can be stirred.
In addition, the garbage discharged from kitchens has a high water content, the viscosity of the bacterial bed increases as the fermentation progresses, and when the stirring member such as a screw is continuously rotated in the same direction, the bacteria containing the garbage can be removed. Lumps easily form on the floor. When a large fermenter is stirred, a large stirring member is required. When the stirring member is large, the rotation resistance is increased, so that a large torque is required and the rotating device is complicated.

[0004] Further, simply inserting an injection pipe into the waste can supply air only to the periphery of the injection pipe, so that air cannot be supplied uniformly to the garbage in the fermentation tank. When the bacteria place containing garbage solidifies due to the rotation of the stirring member, there is a problem that it becomes difficult for air to enter the inside.

[0005] Therefore, the present invention can reduce the size of a device required for driving the stirring means even in a large processing tank, and can uniformly stir the carrier and the waste in the processing tank . aims to provide a processing apparatus, also aims to provide a processing apparatus for waste can be uniformly supplied air into the carrier containing the waste.

The fermenter 1 is supported by three support legs 131, and the support legs 131 are provided with a weight measuring means 132 for measuring the weight of the fermenter 1.

Next, the operation of the fermentation treatment apparatus will be described. In this fermentation treatment apparatus, about 1000 to 1500 kg of the bacterial bed K is put into the fermenter 1, and about 500 kg at a time. The fermentation process is performed by inputting waste H. The bacterial bed K is a carrier for microorganisms, and uses sawdust and the like. First, the opening / closing lid 72 of the hopper 71 is opened and the waste H is introduced into the inside, and the waste H is pulverized by the pulverizer 73. In the pulverizer 73, metal foreign matters and the like are separated by the detection of the torque limiter 121. The waste H crushed by the crusher 73 is transferred to the closed tank 80 by the screw conveyor 77, and the waste H collected in the closed tank 80 is carried into the fermenter 1 by the screw conveyor 82, and a predetermined amount of waste When H is carried into the fermenter 1, the on-off valve 85 is closed. Next, when the ascending transfer means 25 is driven,
The waste H rises up the cavity 45 in the outer rotary cylinder 37, and the cavity H
45 is sent out from the upper opening 45A, and the cavity
The waste H is sucked into the cavity 45 from the lower opening 45B of the cavity 45, and the waste H and the bacterial bed K move from above to below outside the cavity 45. In this case, the waste H outside the cavity 45
The bacterial bed K moves downward along the reducing portion 3 and tends to solidify under the blade body 34 due to a load received from above. However, when the expansion / contraction driving means 61 is driven, the outer rotary cylinder 37 reciprocates, A tooth portion 47 is provided at the lower end of the outer rotary cylinder 37, and the rotating tooth portion 47 cuts the lump, so that the lower waste H and the bacterial bed K are smoothly sucked into the hollow portion 45.
Also, when the telescopic drive means 61 is driven and the telescopic rod 61B expands and contracts, the blade body 34 rotates approximately 30 degrees clockwise and 30 degrees counterclockwise from the position before rotation,
The blade body 34 is driven to reciprocate in a range of approximately 60 degrees, which is a predetermined angle, and one blade body 34 stirs the waste H and the bacterial bed K in a range of approximately 120 degrees (θ).
In this case, the fermenter 1 has a blade rotating cylinder 12 as a center,
Since the blade body 34 having the angle θ of 60 degrees is provided,
By rotating by 30 degrees in the forward and reverse directions from the position before the rotation, the waste H and the bacterial bed K of the entire fermenter 1 are stirred,
By driving the ascending transfer means 25 and the blade body 34, the input waste H and the bacterial bed K are uniformly mixed. At the same time as the blade body 34 is stirred, the air supply pipes 51, 51A, 51B, 51
Air is blown out from the outlet 56 of C, and oxygen is supplied into the waste H and the bacterial bed K. In this case, a plurality of blades 38, 38
Since A, 38B, and 38C move so as to cut through the bacterial bed K containing the waste H, the bacterial bed K containing the waste H is not compacted, and the waste material is compared with the conventional stirring. The bacterial bed K containing H is hard to solidify, and the torque required for the reciprocating rotation drive of the blade body 34 can be reduced. In addition, since the plurality of air supply pipes 51, 51A, 51B, and 51C are reciprocated and driven to blow air into the bacterial bed K containing the waste H together with the blade body 34, the waste H is contained. Oxygen is supplied to the entire bacterial bed K. Further, air is supplied to the bacteria bed K containing the waste H in the outer rotary cylinder 37 through the hole 46. Then, when the waste H starts to be decomposed, the temperature of the bacterial bed K rises due to the fermentation heat, for example, the temperature rises to about 60 to 70 ° C.,
Although the viscosity of the microbial bed K increases, the thin plate-shaped blade body 34 having a plurality of openings 43 is reciprocally driven to rotate, so that the reaction force associated with the rotation can be reduced, and the waste H
Can be agitated so as to cause convective transport to the bacterial bed K containing. The blade rotating cylinder 12 is reciprocatingly driven at a low speed, and reciprocates in a range of 120 degrees per minute, for example.

Further, the waste H such as garbage has a high water content, generates heat as the fermentation progresses, and increases the moisture in the waste H. The water content of garbage is the sum of the moisture contained in the solid content and the water content that is different from the solid content. Water to be used. During the fermentation of the waste H, the air passing through the return pipe 99 is:
Preheated to about 30 to 60 degrees by heating means 100,
The heated air is blown out from the outlet 56 by the drive of the blower 101, and thereby the bacterial bed K containing waste H is discharged.
Is heated. Due to the heat applied by the heating means 100 and the fermentation heat of the waste H, the air in the upper part of the fermenter 1 contains steam. When the blower 101 is driven, a negative pressure is generated on the exhaust pipe 91 side, and the air in the fermenter 1 is sucked into the closed tank 80 side. A blower 94 for supplying outside air is provided in the middle of an exhaust pipe 91 connecting the fermenter 1 and the closed tank 93. The blower 94 sends outside air toward the closed tank 93, and
In 80, the air is cooled by the heat exchanger 95, and the moisture of the steam is separated as water. Outside air is supplied to the closed passage 102 by the blower 94, and the supplied air is burned in the combustion processing device 98. In this way, the outside air is fed into the fermenter 1 by the blower 94 to supply oxygen necessary for fermentation, while the air containing the odor from the fermenter 1 is burned to be deodorized. Then, in the fermenter 1, when the waste H is fermented and decomposed by the activity of the aerobic microorganisms, water, carbon dioxide, ammonia, hydrogen sulfide, and the like are generated, and the odor due to these is eliminated by the combustion treatment.

After the waste H is fermented as described above, if the residual waste H accumulates in the bacterial bed K, the next waste H
Before charging, the residual waste H is separated from the bacterial bed K in the fermenter 1 by the separating means 142. For example, residual waste H
Examples include ash after waste H fermentation, lignin that is not decomposed, cellulose, vinyl, and the like. First, the screw conveyor 17 is driven to transfer the bacterial bed K upward, and the branch pipe is moved.
Put into the centrifugal filter 113 from 111. The centrifugal filter 113 is driven to rotate and reciprocate in the longitudinal direction.
The sawdust falls from the dropping port 114 into the fermenter 1, and the residual waste accumulates in the centrifugal filter 113, and the accumulated residual waste H is discarded.

Further, weight measuring means provided on the support leg 131
At 132, the weight of the fermenter 1 is measured and observed. First,
After the waste H is charged, the weight of the fermenter 1 is measured, the above-described stirring and air supply are performed, the weight of the fermenter 1 during fermentation is measured, and the fermentation state is confirmed based on the weight. That is, if the input waste H such as garbage has a water content of, for example, 85% or more, the amount of water in the fermenter 1 becomes excessive, the activity of the aerobic microorganisms is stopped, and the progress of fermentation is hindered. Therefore, even when the apparatus is driven, the weight of the fermenter 1 does not decrease as compared with the case where the fermentation is performed well.
Further, even when a large amount of foreign matter is mixed in the waste H, the foreign matter does not ferment. Therefore, after the fermentable waste H is fermented, the weight of the fermenter 1 does not decrease. Therefore, by monitoring the weight of the fermenter 1, the fermentation state can be confirmed.

As described above, in this embodiment, according to the first aspect, the bacterial bed K as a carrier in the fermenter 1 as a treatment tank and the waste
In the waste H treatment apparatus for stirring H, a vertically extending hollow part 45 is vertically provided in the fermenter 1, and in this hollow part 45, an ascending transfer means 25 for sending the waste H upward is provided.

25, the waste H and the bacterial bed K are transferred from the bottom inside the cavity 45 to the top, and circulate from the top outside the cavity 45 to the bottom. H and bed K
Since the blades 38, 38A, 38B, 38C, 39, 40 are reciprocatingly driven in the inside, the waste H and the bacterial bed K are stirred downward and in the rotational direction of the blades 38, 38A, 38B, 38C, 39, 40. Is done. Further, since the blades 38, 38A, 38B, 38C, 39, and 40 are reciprocally rotated so as to cut the bacterial bed K containing the waste H, the bacterial bed K containing the waste H is hardly solidified. A large torque is not required, and in a device equipped with a large fermenter 1, the device required for rotational driving can be small,
A large amount of waste H exceeding 500 kg can be eliminated. In addition, in the case of a bacterial bed containing waste H that has undergone caking due to fermentation, if the stirring is performed at a relatively high speed by a conventional stirring means, the bacterial bed containing waste H is formed by the granulation action. Lumps are generated on the floor K and air permeability is lost, but the flat blades 38,
By stirring the 38A, 38B, 38C, 39, 40 with reciprocating rotational movement, the bacterial bed K can be brought close to the state before fermentation. Then, the air supply pipes 51, 51A, 51B, 51C are reciprocally rotated together with the blades 38, 38A, 38B, 38C, 39 to supply air uniformly from the outlet 56 into the bacteria bed K containing the waste H.

Further, since the outer frame blade 35 having a shape along the inner surface of the fermenter 1 is provided outside the blade body 34, the waste H and the bacterial bed K on the inner surface of the fermenter 1 can be evenly stirred. Further, since the frame plates 35, 41, and 42 are formed in an arc shape centering on the blade rotating cylinder 12, rotation resistance is small. Further, since the end of the oblique blade 40 is welded to a position deviated from the cross weld 44, the waste H and the bacterial bed K hardly adhere to the cross weld 44. Also, air supply pipe 5
