2. Description of the Related Art As a conventional decomposition processing apparatus, there is one disclosed in Japanese Patent Application Laid-Open No. 11-300324 by the applicant of the present application. This decomposition treatment device is for microbial decomposition treatment of organic waste such as manure and garbage, and has a high decomposition treatment capacity by highly efficiently stirring and mixing sawdust and organic waste and activating microorganisms. In addition, it has many excellent effects such as effective use of decomposed organic waste and sawdust as high-quality fertilizers and soil conditioners. It is used in processing machines.

By the way, when the manure discharged from the barn is processed by the above-mentioned conventional decomposition processing apparatus, the cow discharges about 40 to 50 times as much urine as human, so that the urine increases the water content in the processing tank. It is feared that the excess amount will be accumulated on the lower side in the treatment tank and the treatment capacity will be deteriorated by microbial decomposition. In addition, in the case of treating manure discharged in barns, the discharged organic waste contains not only manure but also litter such as straw and sawdust. There is a concern that it will be over. That is, if the amount of the organic waste is too large, the organic waste cannot be completely collected in the processing tank, and the driving unit of the stirring mechanism for stirring the organic waste and the sawdust in the processing tank is excessive. There are obstacles such as a load. Therefore, in order to deal with the treatment of manure discharged in barns with a conventional decomposition treatment device, it is necessary to increase the size of the treatment tank, but it is difficult to transport the decomposition treatment device on site. Improvement was required because of having it.

The organic waste communication passage 60 has adjacent treatment devices, that is, the high temperature treatment device 21 and the first intermediate temperature treatment device 2.
2, and the first intermediate temperature processing device 22 and the second intermediate temperature processing device 23
Is provided with a rectangular opening on the side surface of the casing 1 so that the processing tanks 4 and 4 communicate with each other.
Have been contacted by. The organic waste communication passage 60 connects the adjacent processing devices on the upper side thereof to remove excess organic waste and sawdust in the processing device on the upstream side (high temperature processing device 21 side). It is circulated in the pipe 61 and transferred to the processing device on the downstream side (the second intermediate temperature processing device 23 side). That is, when the organic waste and the sawdust are excessive in the processing tank 4, the excess organic waste and the sawdust are discharged into the organic waste communication passage 60. Then, when the organic waste and the sawdust discharged into the organic waste communication passage 60 are further supplied to the treatment tank 4, the organic waste and the sawdust are pushed by the supplied organic waste and the sawdust, Extruded into the adjacent processing unit. still,
The organic waste and the sawdust transferred through the organic waste communication passage 60 are the organic waste and the sawdust having a relatively small amount of water in the upper layer portion in the processing tank 4.

The pipe body 61 smoothly feeds excess organic waste and sawdust on the upstream side to the downstream side.
The vertical and horizontal passage dimensions and passage lengths are set. Incidentally, in the unlikely event that the pipe 61 is clogged with organic waste and sawdust, an inspection port (not shown) that can be opened and closed as needed is provided on the upper surface of the pipe 61.

The moisture communication passage 70 is provided with a large number of small holes 71 on the side surface of the housing 1 so that the processing tanks 4 and 4 of adjacent processing apparatuses communicate with each other, and a duct-like tubular body 73.
Have been contacted by. And this moisture communication passage 70
Connects the adjacent processing devices on the lower side thereof to allow excess water such as urine in the upstream processing device to flow into the pipe 73 and be transferred to the downstream processing device. That is, the water accumulated in the lower layer portion in the processing tank 4 is sent to the processing device on the downstream side. The upper and lower positions of the moisture communication passage 70 are preferably at least lower than the rotary shaft 10, that is, lower than the rotary shaft 10 so that the moisture in the processing tank 4 can be prevented. This is because it is possible to prevent leakage from the bearing portion that supports the shaft to the outside.

The tube 73 has vertical and horizontal dimensions and passage lengths so that excess water on the upstream side can be smoothly sent to the downstream side. Incidentally, the small hole 71 on the side surface of the housing 1
Sets its inner diameter so that only water passes through as much as possible to prevent the inside of the pipe body 73 from being clogged with organic waste and sawdust, but the organic waste and sawdust flow out into the pipe body 73. In order to prevent this, the large number of small holes 71 may be replaced with a fibrous filter or mesh plate. Further, in the unlikely event that the pipe 73 is clogged with organic waste and sawdust, an inspection port (not shown) that can be opened and closed as needed is provided on the upper surface of the pipe 73.

The recovery box 30 is connected to the second intermediate temperature processing device 23 through an organic waste communication passage 60 '. The recovery box 30 is the processing device 2 described above.
By removing the stirring section A, the driving section 24, and the heater 5 from 1.22 and 23, the processing apparatus 21.22 and 23 are configured as common parts (see FIG. 5). Therefore, detailed description of the same components as those of the processing devices 21.22 and 23 will be omitted.

The recovery box 30 is a substantially hollow box body in which a storage tank 4'of the same member as the processing tank 4 is provided in the housing 1, and the organic waste communication passage 60 'provides a second intermediate temperature. By contacting the processing device 23, the recovery box 30
The inside of the storage tank 4 ′ is communicated with the processing tank 4 of the second intermediate temperature processing device 23 (see FIG. 4).

The part of the second intermediate temperature processing unit 23 that communicates with the recovery box 30 is on the upper side of the side surface (the side surface on the long side of the housing 1) parallel to the rotating shaft 10 of the stirring section A and the stirring is performed. It is preferable that the surface on the side where the organic waste and sawdust in the processing tank 4 is brought by the rotation of the part A.
That is, by making the contact points as described above, the organic waste and sawdust in the upper layer portion having a relatively low water content are caused to flow out into the pipe body 61 ′, and the outflow at that time is assisted by the rotation of the stirring section A. This is because

Therefore, the organic waste communication passage 60 'connecting the second intermediate temperature processing device 23 and the recovery box 30 is
The width dimension of the tubular body 61 ′ constituting the passage is adjusted to the side surface on the long side of the housing 1, and the organic waste communication passage 6 described above is provided.
It is set wider than 0. Other than that, the basic configuration of the organic waste communication passage 60 'is the same as that of the organic waste communication passage 60 described above, and thus the duplicated description will be omitted.

Further, in the recovery box 30, an openable and recoverable recovery port 31 is provided on the side surface opposite to the side surface having the organic waste communication passage 60 ', and the organic material accumulated in the storage tank 4'is provided. Waste and sawdust can be collected regularly.

According to the decomposition treatment system X having the above structure, first, the organic waste is supplied into the high temperature treatment equipment 21 through the supply passage 81. Then, the supplied organic waste is agitated and mixed with sawdust in the high-temperature treatment device 21 and heated to a high temperature by the heater 5, so that harmful bacteria in the treatment tank 4 are sterilized and the organic waste is discarded. Water such as urine contained in the substance is evaporated and discharged from the exhaust pipe 8. At this time, the high temperature treatment apparatus 21 also decomposes microorganisms in the treatment tank 4, but since the inside of the treatment tank 4 is heated to a high temperature by the heater 5, its main functions are sterilization and evaporation of water.

The excess organic waste, sawdust, and water in the high-temperature treatment device 21 are in the pipe body 61 of the organic waste communication passage 60 and the pipe body 7 of the water communication passage 70, respectively.
By circulating the inside of
The organic waste and sawdust that have been transferred to the second intermediate temperature processing device 22 and have become excessive in the first intermediate temperature processing device 22 are further transferred to the second intermediate temperature processing device 23. First medium temperature processing device 22 and second medium temperature processing device 23
Since the temperature is set by the heater 5 so that the microorganisms in the treatment tank 4 are efficiently decomposed, the treatment tank 4
Although there is evaporation of water inside, the main action is microbial decomposition treatment.

Then, the excess organic waste and sawdust in the second intermediate temperature treatment device 23 are treated as the organic waste communication passage 6
It is transferred to the inside of the recovery box 30 by flowing through the 0 ′ tube body 61 ′ and is stored in the recovery box 30. The stored organic waste and sawdust are regularly collected from the collection port 31. In the example of this embodiment, the collection frequency is about 2-3 times a year.

In the above embodiment, one high-temperature processing device having sterilization and evaporation of water in the processing tank 4 as main functions is provided,
Two medium temperature treatment devices whose main function is to efficiently promote the decomposition of microorganisms in the treatment tank 4 are used. However, the amount of water contained in the organic waste and the amount of the organic waste supplied from the supply path 81 are reduced. The number of each of the high temperature processing device and the medium temperature processing device may be increased or decreased according to the amount.

The direction in which each of the processing devices 21.22 and 23 is arranged is not limited to the illustrated example, and any or all of the processing devices may be substantially orthogonal to the illustrated example. You may arrange in the direction to do. For example, each of the processing devices 21.22 and 23 may be arranged so that the rotation shafts 10 thereof are substantially parallel to each other, and the processing devices may be connected to each other by the organic waste communication passage 60 and the moisture communication passage 70. . In this case, in the illustrated example, the second intermediate temperature processing device 23
As if the recovery box 30 was communicated with the collection box 30, the outflow of organic waste and sawdust into the organic waste communication passage 60 is caused by the stirring section A.
It is preferable that the side where the organic wastes and sawdust are gathered by the stirring section A is the downstream side so as to be assisted by the rotation of the.

[0041]

Since the present invention is constructed as described above, it has the following effects. (Claim 1) Since a plurality of treatment devices are connected to each other through the organic substance communication passage and the moisture communication passage, even if an organic waste of more than that capacity is supplied to the treatment tank of the upstream treatment device, its capacity is increased. Over the amount of organic waste and sawdust,
The moisture can be sequentially transferred to the processing device on the downstream side. Therefore, even if a large amount of water is contained in organic waste such as manure discharged in a barn, the water is dispersed in multiple treatment devices, and excessive water impedes the promotion of microbial degradation. It is possible to reduce the degradation of the decomposition processing capacity. In addition, when the amount of organic waste is expected to be large, such as when litter is discharged from cowsheds together with manure, increase the number of treatment equipments that are connected by the organic matter communication passage and the moisture communication passage. Thus, the decomposition treatment capacity can be easily increased without increasing the size of each treatment tank. Shi
Also, the recovery box should be contacted to the processing equipment on the most downstream side.
Therefore, the organic waste after decomposition processing is
Since the sawdust can be transferred,
In addition to improving the storage capacity, each processing device due to excess capacity
It is possible to prevent the drive unit of the above from being overloaded. In addition, the recovery
Organic waste and sawdust are stored in the
The collection cycle can be extended to reduce the collection frequency.
It (Claim 2) In addition, if the inside of the treatment tank is sterilized by the high temperature treatment equipment and the water in the treatment equipment is evaporated, harmful bacteria can be prevented from being generated and the decomposition treatment ability due to excessive water content can be improved. The decrease can be further reduced.
