It can also be controlled by manual control.

Therefore, according to the livestock manure processing apparatus according to the embodiment, manure processing is performed as follows. The lid 16 of the hopper 12 of the processing object supply unit 11 is opened in advance, and the processing object S, which is manure, is put into the hopper 12. Then, the lid 16 is closed, and the auger 14 is
Is rotated to feed the supply pipe 13 from the bottom 12a of the hopper 12.
The processed material S is supplied to the foremost decomposition tank 20A from the opening 13a through the opening 13a. In addition, peat moss and bacteria are added for this input.

Further, in the foremost decomposition tank 20A, while the processing object S is accumulated to some extent, the stirring body 42 of the stirring mechanism 40 is driven to rotate, and the air heated from the pipe 51 of the air supply unit 50 is removed. Blow out. As a result, the bacteria are activated, so that the treated product S is decomposed by the bacteria while being stirred. And the foremost decomposition tank 20A
Is decomposed while moving over the partition wall 21 toward the decomposition tank 20 at the rear. That is,
When the processed material S supplied to the preceding decomposition tank 20 and decomposed reaches the height of the partition wall 21, it is gradually supplied to the rear decomposition tank 20 over the partition wall 21. In this case, since there are a plurality of decomposition tanks 20, the processed material S supplied to the downstream decomposition tank 20 is decomposed and dried to some extent in the front decomposition tank 20, so that the treatments having different degrees of decomposition are performed. Mixing of the material S is suppressed, that is, the situation in which the initial decomposition, the middle decomposition, and the final decomposition are easily mixed is suppressed, so that the decomposition accuracy of the processed material S is improved accordingly. Can be.

In this case, in each decomposition tank 20, as shown in FIGS. 1 and 6, the stirring member 42 includes the spiral member 45 and the stirring blade 47 having different feeding directions. The processing object S is moved in one direction to the left and right while being stirred up and down, and at the same time is moved in the other direction to the left and right while being stirred up and down. Therefore, the processed material S is moved and stirred not only in the vertical direction but also in the horizontal direction, so that the processed material S is well exposed to the heated air, so that bacterial decomposition is promoted and the decomposition efficiency is greatly improved. .

Further, since the spiral body 45 of the stirring body 42 is formed in a circular cross section, the spiral body 45 is hardly subjected to a large resistance due to the processed material S to be dried, so that the load acting on the rotating shaft 41 and the driving unit 43 is reduced. , And can be reliably operated. In addition, since it is spiral, air circulation can be improved, and in this respect, processing efficiency can be improved. Furthermore, since the bottom surface 20a of each decomposition tank 20 is formed in an arc surface parallel to the rotation locus of the tip of the stirring body 42, the bottom surface 20a is smaller than the bottom surface 20a of the decomposition tank 20 formed in a rectangular box shape. The unprocessed processed material S does not remain in the corners of the above, and in this regard, the processed product S can be reliably processed. Further, as shown in FIG. 4, the rotating shaft 41 is formed by inserting a cylindrical body 41b having a rectangular cross section into a cylindrical shaft 41a, so that the outer shape is angular. In comparison, even if straw or the like contained in manure is entangled, it is easily removed.

During the decomposition of the bacteria, the processed material S is decomposed by exposure to warm air, so that the temperature of the processed material S becomes high and evaporates. This evaporating water rises and the lid 30
Since the ceiling surface is curved so as to have a substantially circular cross-section, the evaporated water condenses, flows downward to the side, and falls into the first gutter 36. Further, the evaporated water adhering to the surface of the partition plate 35 is condensed and flows down, falls into the second gutter 37, and further travels down the second gutter 37 and falls into the first gutter 36. And
The gas is discharged from the discharge pipe 38 to the outside along the first gutter 36. In this case, the evaporated water is supplied to the first and second gutters 36,
Since it is collected in the treatment tank 37, it is difficult to fall into the processed material S in the decomposition tank 20, so that the processed material S is surely dried, and the processing efficiency is improved accordingly. Also, since the partition plate 35 is provided and the second gutter 37 receives water,
Compared to the case where only the ceiling 34 without the partition plate 35 is used, the water recovery efficiency is extremely high, it is possible to further prevent the falling into the processed material S, and it is possible to surely dry the processed material S. . Further, since a plurality of cooling fins 39 are provided on the outer surface of the lid portion 30, the cooling efficiency of the ceiling 34 is good, and therefore, the attached evaporating water is rapidly dewed, so that the collecting efficiency is good. The processing efficiency is improved.

In this case, the suction fan 67 of the exhaust device 60 is driven, and the gas generated in the decomposition tank 20 and the storage tank 25 is exhausted together with the water vapor. In the exhaust device 60, since the branch pipe 61 is provided for each of the decomposition tanks 20, the exhaust efficiency is improved accordingly. In this case, steam is also exhausted, so in this regard,
The recovery efficiency of the evaporating water is improved, and the processing efficiency of the processing object S is improved. Furthermore, since the branch pipe 61 is provided at the top of the lid 30, it does not easily obstruct the water flowing down the ceiling 34, and in this regard, the water recovery efficiency is improved. That is, when the branch pipe 61 is provided on the side, the water that flows down easily falls into the decomposition tank 20 when reaching the opening of the branch pipe 61. However, in the present embodiment, this is prevented. is there. Then, the gas is cooled in the cooling pipe 63, and the water vapor contained in the gas is liquefied. This water may be discharged from the water discharge portion 64 made of drain at an appropriate time. Further, the odor component of the gas is adsorbed by the deodorizing pipe 65 of the exhaust device 60. Therefore, a situation in which an offensive odor is released to the outside is prevented.

When the processed material S decomposed in the last decomposition tank 20D reaches the height of the height adjustment plate 22 of the partition wall 21, it is supplied to the storage tank 25 little by little through the height adjustment plate 22. To go. When a certain amount of the processed material S is stored in the storage tank 25, the screw conveyor is driven to take out the processed material S from the outlet 26. The processed material S at this stage is:
Decomposition is progressing to brown powder, so that it can be used as an organic fertilizer or incinerated. In the processing apparatus according to the above-described embodiment, by appropriately setting driving conditions, for example,
00 liters of manure (processed material S having a water content of about 90 to 95%) is reduced to about 7 liters (about 1/60) in about one week of treatment.

In the above-described processing, a certain amount of the processed material S is present in each tank because the processed material S to be processed in each tank stops at each tank and moves to the next over the partition wall 21. This is a process of continuously supplying the processing object S so as to continue. Further, in the above embodiment, each decomposition tank 20 and storage tank 25
The capacity of each tank may be determined according to the amount of manure to be processed. In addition, it is needless to say that the operating conditions of each part may be appropriately determined according to the amount and properties of the manure.

[0027]

As described above, according to the garbage disposal apparatus of the present invention, a partition plate hanging down to the partition wall is provided on the ceiling of the lid, and the first and second partitions are provided on the opening edge of the lid and the partition plate. A second gutter is provided to discharge water that adheres to the ceiling or the partition plate and falls, so the evaporating water from the processed material is collected in the first and second gutters and falls into the processed material. Therefore, it is possible to surely dry the processed material and to greatly improve the processing efficiency. In particular, since a partition plate is provided to receive water even in the second gutter, the water recovery efficiency is extremely high as compared to the case of only the ceiling without the partition plate, and the processed material is more reliably dried, Processing efficiency can be improved.

In the case where the ceiling of the lid is formed in a semicircular cross section, water condensed on the ceiling is smoothly transmitted and easily flows to both sides, so that the water can be more difficult to fall into the treated material. is there. Furthermore, when a plurality of cooling fins are provided on the outside of the lid, the cooling efficiency of the ceiling can be increased, and the attached evaporated water can be rapidly condensed and collected. The processing efficiency of the object can be improved.

Further, when the exhaust system is provided with a plurality of branch pipes corresponding to each decomposition tank and a cooling pipe for cooling gas in a main exhaust pipe connected to each branch pipe, each decomposition pipe is provided. Since a branch pipe is provided for each tank and steam can be liquefied in the cooling pipe, the exhaust efficiency can be improved accordingly, and the recovery efficiency of the evaporated water in the exhaust gas can be improved. The processing efficiency of the processed material can be further improved. In addition, when the branch pipe of the exhaust device is provided at the top of the lid, it does not hinder the water flowing down the ceiling, and in this respect, there is an effect that the water recovery efficiency can be improved. Also, if a deodorizing pipe that contains a deodorant that adsorbs gas odor components is connected to the downstream side of the cooling pipe of the exhaust device, the gas odor components are adsorbed, and an odor is released to the outside. Can be prevented.

When the stirring mechanism is constituted by providing a stirring body on a rotating shaft and the bottom surface of each decomposition tank is formed by an arc surface parallel to the rotation locus of the tip of the stirring body, it is formed in a rectangular box shape. As compared with the bottom surface of the decomposition tank, no unstirred processed material remains in the corner portion of the bottom surface. In this regard, the processed material can be reliably processed, and the processing efficiency can be improved. Furthermore, when the stirrer of the stirrer mechanism is provided with a spiral body having a circular cross section that is wound around the rotation axis substantially, there is a gap because the spiral body has a spiral shape, so that air circulation can be improved. In this respect, the processing efficiency can also be improved at this point, and since the spiral body is formed in a circular cross section, resistance is hardly applied by the processed material to be dried,
For this reason, it is possible to reduce the load acting on the rotating shaft and the drive unit and to operate the drive unit reliably. Furthermore, when the stirrer of the stirrer is configured to include a spiral body and stirrer blades having different feeding directions, the processing object can be moved not only up and down but also in the left and right direction to stir. The object can be well exposed to air, and the decomposition efficiency of the processed object can be greatly improved.

Further, a processing material supply unit is provided adjacent to the foremost decomposition tank and into which a processing material is introduced, and is connected to the bottom of the hopper and extends in the direction in which the decomposition tank is connected.
