廃棄物その他の有機性廃棄物などの堆肥化発酵槽の運転
方法及びその攪拌装置に関するものである。[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a method for operating a fermentation tank for composting municipal waste, sewage sludge, livestock waste, agricultural waste and other organic waste, and a stirring device therefor. It is related to.

料の均質化や曝気の均一化、暖気表面積の実質的拡大な
どの理由から、攪拌は必須な操作である。Composting organic waste etc. is usually done using materials (composting raw materials).
This is done by storing the material for a certain period of time, and during this period, stirring at appropriate intervals while supplying an appropriate amount of air from the floor surface, and performing a turning operation on the material to promote aerobic fermentation. Furthermore, although air supply from the floor may be omitted, stirring is an essential operation for reasons such as homogenization of the material, uniformity of aeration, and substantial expansion of the heated surface area.
堆肥化操作を合理的に行うためには、前記攪拌と同時に
材料を一定方向に移送する機能が望ましく、このために
攪拌と移送を同時に行い得る回転パドルを有する攪拌手
段が必要となり、 ＵＳＰ４４１０３４８等の発明がな
されている。In order to perform the composting operation rationally, it is desirable to have a function of transferring the material in a fixed direction at the same time as the stirring, and for this purpose, a stirring means having a rotating paddle that can perform stirring and transfer at the same time is required, such as USP 4410348 etc. Inventions are being made.

全材料を攪拌、移送せしめるものである。The invention moves a rotating paddle-type stirring device, which has the function of transporting materials in substantially the same direction by stirring, along a zigzag-like trajectory having components in both directions, approximately perpendicular and parallel to the direction in which the materials are transported. By forcing
This allows all materials to be stirred and transferred.
即ち、このような堆肥化操作の原理を第５図及び第６図

の攪拌装置を示す。That is, the principle of such a composting operation will be explained with reference to FIGS. 5 and 6. Reference numeral 101 denotes a rotating paddle type stirring device which has both the function of locally transporting the material by a short distance (referred to as material movement distance) in the direction of arrow 102 and the function of stirring.

け矢印１０２の方向に全量移送が完了する。The stirring device 101 has a starting point 10 near the compost outlet end 103.
4, the zigzag as shown consists of arrows 106 and 106' indicating a short distance movement in the longitudinal direction, indicating a lateral movement approximately perpendicular to the compost transfer direction of arrow 102. When the material moves along the trajectory of the shape and reaches the end point 108 near the material inlet end 107, all the materials are transferred by the stirring operation of the stirring device 1 as described later, and the composting raw material is transferred from J→discharge to I- JSH→I, −・−・−・−
1B-C and AB, the entire amount is completely transferred in the direction of the arrow 102 by the material movement distance.

っている。As shown in FIGS. 6 and 7, this rotary paddle type stirring device 101 consists of a pedestal 1 that runs in the vertical direction of a fermenter 111.
The fuselage 1 can run horizontally on the fermenter 111 on the top of the fermenter 111.
It is composed of a rotating paddle 122 suspended from a rotary paddle 122, and the rotating paddle 122 is rotated backwards with respect to the longitudinal direction of movement within the fermenter 111 (arrow 115).
It is designed to move the material by flinging it in the direction of 02.

体を−わたり攪拌し堆肥化原料を移動させる切返し操作
を１回／日程度の頻度で行う。従って発酵槽１１１内の
ある部分の堆肥化原料は１回７日の攪拌による切返しを
うけることになる。In such a conventional method, a turning operation to stir the entire fermentation tank 111 and move the composting raw material is usually performed at a frequency of about once a day. Therefore, the composting material in a certain portion of the fermenter 111 is subjected to stirring once every 7 days.
この程度の頻度の切返し操作は、有機分の多い原料或い

返しをうけるため、原料温度が低下し、十分な発酵が得
られない場合がある、という問題点を有していた。This frequency of turning operations is a very effective method for raw materials with a high organic content or during a period of active fermentation in the early stage, but on the contrary, it is a very effective method for raw materials with a high organic content or during the early stage of active fermentation. During the slow period, as shown by the dotted line in Figure 8, the temperature of the raw material may drop and sufficient fermentation may not be achieved because the fermentation temperature is cut short before reaching a sufficient fermentation temperature. It had a point.

って３週間の発酵期間内における最適攪拌回数は１２〜
１４回程度である。なお、この数値は、回転パドルを用
いて攪拌を行った場合のものであって、他の攪拌方式で
は異なる数値となる。For example, in general, primary and secondary fermentation of raw materials such as kitchen waste, livestock dung, and straw is completed after about 3 weeks of fermentation, and although this is not a strict value, secondary fermentation can be completed in about 1 week after the primary fermentation period. The period is approximately 2 weeks. During this period, it is desirable to stir about once per day during the next fermentation period, and
During the secondary fermentation period when bacterial activity is slightly reduced, stirring approximately once every 2 to 3 days is considered desirable. Therefore, the optimal number of stirrings within a 3-week fermentation period is 12~
About 14 times. Note that this value is for the case where stirring is performed using a rotating paddle, and the value will be different for other stirring methods.
即ち、１２〜１４回程度の攪拌を受けた場合の堆肥化物
の移動距離は１５〜２０ｍ程度となる。That is, the moving distance of the composted material when it is stirred about 12 to 14 times is about 15 to 20 m.
これ以上の攪拌操作は本来不要なものである。Further stirring operations are essentially unnecessary.

間に大幅なずれが生じることとなる問題もあった。In addition, in order to process a large amount of composting material, the width of the fermenter must be increased, and along with this, the distance between the running rails that are laid on both sides of the fermenter is also wide. This caused the running beams placed across the space to become huge. On the other hand, if the width of this running rail is kept within a certain range, the shape of the fermenter will be
It is long along the running rail, and the distance between the inlet end and the outlet end of the composting material becomes long, so the compost material is collected within a predetermined time (the time required from the start to the end of fermentation). There was also the problem that the distance traveled was naturally long, resulting in a large discrepancy between the number of times of stirring required to transfer the composted material and the number of times of stirring necessary for proper fermentation.

ている。FIG. 1 is a plan view showing an example of a fermenter according to the present invention. In FIG. 1, reference numeral 1 denotes a fermentation area having a rectangular planar shape, and is composed of four sides 2 to 5. A running rail 6.7 as a guideway is laid outside the sides 2 and 3 of the fermentation area l, and this running rail 6.7
The intervals are almost equal. Then, the running beam 8 is passed between these two running rails 6 and 7, and the running rail 6.
It is installed so that it can run freely on the 7°. Furthermore, an agitator 9 is provided on the running beam 8 so as to be able to move freely along the running beam 8.
この第１図においては攪拌機９、走行梁８の具体的な構

５の外側を通過して再び始点Ａにもどる。The stirrer 9 moves to the starting point A by the operation of the stirrer 9 and the running beam 8.
It moves along a zigzag-like trajectory as shown by the arrow, and reaches the end point B by stirring the compost deposited throughout the fermentation area 1. Thereafter, it passes through the outside of side 5 of fermentation area 1 and returns to starting point A again.

れるが、このことを第２図で詳しく述べる。Of course, in the present invention, the moving trajectory of the agitator fi9 is not a smooth line per stroke of 1M.By the movement of the agitator 9 shown in Figure 1, the entire composted material in the fermentation area 1 is spread over the running rail. 6 side to the traveling rail 7 side, and this will be described in detail in FIG. 2.

の重量に応じて増減できる。A rotary paddle 10 is suspended from the stirrer 9 by a support 14 and is rotated by a remoter 15. In addition, since the rotating surface of the rotating paddle IO is set to be perpendicular to the running rail 6.7, that is, parallel to the running beam 8, the composted material is transferred to one side regardless of the rotating direction of the rotating paddle IO. It will be transferred from one running rail side to the other running rail side. The running beam 8 is designed to move on a running rail 6 with two trees on one side.
It can be increased or decreased depending on the weight.

The side surfaces can stir the deposited layer. 16 in Figure 3
is a drive device for moving the stirrer 9 on the running beam 8, and the motor 15 for driving the rotary paddle 10 is omitted.

堆肥を集めることができる。Therefore, when the operation is repeated according to the trajectory of the agitator shown in FIG. 1, the composted material in the fermentation area 1 is gradually transferred from the side 2 side to the side 3 side, and the raw material is transferred to the supply means (not shown). The composted material is supplied into the fermentation area 1 along the side 2 and is taken out from the end of the side 3 after undergoing a predetermined fermentation process. For this purpose, if a droplet is formed along the side 3 on the floor between the side 3 and the running rail 7, and a belt conveyor is placed under the droplet, the compost can be easily collected.

ことができる。In the above composting process, if the dimensions of the fermentation area 1 are appropriately selected in advance, that is, the distance between the sides 2 and 3 parallel to the running rail 6°7 is equal to the moving distance calculated from the required number of stirrings. If the values are set to be equal or close to each other, there will be no problem such as abnormally lowering of the fermentation temperature due to unnecessary stirring of the composted material deposited in the fermentation region 1. Therefore, as shown by the solid line in FIG. 8, the fermentation temperature reaches an appropriate temperature, a sufficient fermentation period is ensured, and efficient fermentation operation can be performed.
勿論、第１図の発酵Ｈ域工の原料供給を受ける辺２側と
堆肥化物を取り出す辺３側とを別々に攪拌することはで
きないので、二次発酵領域における攪拌回数は若干多く
なる。Of course, it is not possible to separately stir the side 2 side that receives the raw material supply of the fermentation H area shown in FIG. 1 and the side 3 side that takes out the composted material, so the number of times of stirring in the secondary fermentation area is slightly increased.
しかし、従来の如く、多量の原料を発酵処理する場合に
走行梁８の長さをいたずらに長くとり、巨大な走行梁と

を繰り返すこともない。However, when fermenting a large amount of raw materials as in the past, the problem of making the length of the running beam 8 unnecessarily long and creating a huge running beam can be avoided. There is no need to repeat the agitation and transfer operation more than necessary to transfer the sample.

有効となる。Furthermore, the present invention can also be applied to batch-type cases,
In that case, for example, if the raw materials are deposited over the entire area within the fermentation region 1 and the rotary paddle 1o is rotated in the forward and reverse directions, the composted material can be transferred with one stirring. As a result, the fermentation process can be completed within approximately the same area. In such a case, the shape of the rotating paddle shown in FIG. 4 is extremely effective.
なお、前記実施例では、走行梁８が案内路としての走行

略した案内路とすることができる。In addition, in the above embodiment, an example was shown in which the running beam 8 runs on wheels on the running rail 6.7 as a guideway.
By using tires instead of wheels, it is possible to create a guideway without rails.
