Description

発酵分解処理装置Fermentation decomposition processing equipment
　本発明は、有機汚泥等の汚泥や生ごみ等を分解処理する発酵分解処理装置の技術分野に関するものである。 The present invention relates to a technical field of a fermentation decomposition treatment apparatus for decomposing sludge such as organic sludge and garbage.
　今日、有機汚泥等の汚泥や生ゴミ等の被処理物の処理が社会的に大きな問題になっており、これら被処理物をコロニー（微生物担持体）とともに分解処理槽に投入し、発酵分解する等の処理をして無公害化することが提唱されている。この場合、被処理物の分解処理の効率を高めるため、分解処理槽に撹拌装置を設けて撹拌する必要があり、このような撹拌装置として、分解処理槽の上方に走行台車を設け、該台車から垂下した一対の垂下フレームのあいだに横軸回転する撹拌羽根を上下二段に設けて、分解処理槽に投入された被処理物を撹拌しながら台車が分解処理槽を移動するようにしたものが提唱された（特許文献１）。しかるに、前記特許文献１の撹拌装置は、撹拌羽根が上下二段に設けられているため、分解処理槽内の被処理物を主として上層部と下層部とに分かれた撹拌がなされることになるため、撹拌効率に劣るという問題があった。そこで、垂下フレームに、駆動、従動スプロケットを軸承するとともに、これら両スプロケットに無端体を懸回し、該無端体の循環移動により撹拌することにより、分解処理槽内の被処理物を上下に切り返す状態で撹拌するようにして撹拌効率を高めるようにしたものが提唱されている（特許文献２）。 Today, the treatment of processed sludge such as organic sludge and raw garbage has become a major social problem, and these processed materials together with colonies (microorganism carriers) are put into a decomposition treatment tank and fermented and decomposed. It is proposed to make pollution-free by processing such as. In this case, in order to increase the efficiency of the decomposition treatment of the object to be treated, it is necessary to provide a stirring device in the decomposition treatment tank and stir, and as such a stirring device, a traveling carriage is provided above the decomposition treatment tank, and the carriage A stirrer blade that rotates horizontally is provided between a pair of drooping frames that are suspended from the upper and lower stages, and the cart moves through the decomposition treatment tank while stirring the workpiece to be treated in the decomposition treatment tank. Was proposed (Patent Document 1). However, since the stirring device of Patent Document 1 is provided with stirring blades in two upper and lower stages, the workpiece in the decomposition treatment tank is stirred mainly into an upper layer portion and a lower layer portion. Therefore, there was a problem that the stirring efficiency was inferior. Therefore, the driven and driven sprockets are supported on the hanging frame, and endless bodies are suspended around these sprockets, and the endured body is turned upside down by agitating the endless bodies by circulating movement. Has been proposed in which the stirring efficiency is increased by stirring in (Patent Document 2).

　しかしながら、前記特許文献１、２のものにおいて、撹拌装置は走行台車により分解処理槽内を往復反転しながら全域に亘って撹拌するように構成されており、分解処理槽の移動端部では、撹拌装置が分解処理槽の前後壁に近付きながら撹拌作動することにより、被処理物を分解処理槽の移動端側の側壁に押し付けるような圧力が作用する。ところで、余剰汚泥等の被処理物は粘度が高く固まりやすい性質を備えているうえ、予め凝集剤により凝集処理されているため、分解処理槽の移動端部で側壁に押し付けられるような圧力を受けると側壁に圧縮堆積される形態を誘引して側壁に付着した状態で固化する惧れがある。そして、撹拌装置の長時間にわたる往復反転作動に伴い固化した被処理物が側壁に堆積（蓄積）し、撹拌装置の移動範囲が狭められてしまう。しかも、固化した被処理物はこれ以上の分解処理がなされることがなく、この結果、処理効率が大きく低下するという問題があり、ここに本発明の解決すべき課題がある。 However, in the thing of the said patent documents 1 and 2, the stirring apparatus is comprised so that it may stir over the whole region, reciprocatingly reversing the inside of a decomposition treatment tank with a traveling carriage, and in the moving end part of a decomposition treatment tank, stirring is carried out. When the apparatus is agitated while approaching the front and rear walls of the decomposition treatment tank, a pressure is applied to press the object to be processed against the side wall on the moving end side of the decomposition treatment tank. By the way, the material to be treated such as excess sludge has a property of being highly viscous and easily solidified, and is preliminarily coagulated with a coagulant, so that it receives pressure that is pressed against the side wall at the moving end of the decomposition treatment tank. There is a risk of solidifying in a state of attracting the form that is compressed and deposited on the side wall and adhering to the side wall. And the to-be-processed object solidified with the reciprocating reversal operation of the agitator for a long time accumulates (accumulates) on the side wall, and the moving range of the agitator is narrowed. Moreover, there is a problem that the solidified workpiece is not further decomposed, and as a result, the processing efficiency is greatly reduced, and there is a problem to be solved by the present invention.

Incidentally, the recovered material (object to be stirred) dropped from the recess 20 by the left and right transfer body 21 serving as the discharging means can be used as it is, for example, as a fertilizer.
　このように構成された発酵分解装置において、架台６は分解処理槽２の左右側壁３の段差部３ａに沿って前後方向に往復反転移動しながら撹拌装置７による撹拌作動を実施するが、架台６は、撹拌装置７の第一、第二撹拌機９、１０が分解処理槽２の前後何れか一方の側壁４に近接する状態を往復反転移動の移動端として一旦停止し、このとき、撹拌装置７による撹拌作動も停止するように構成されている。そして、前記停止状態を予め設定される待機時間継続し、その後、移動方向を反転し、駆動軸１４の回転方向を逆転して、撹拌作動をしながらの分解処理槽２内における移動を開始するように構成されている。 In the fermentation decomposition apparatus configured as described above, the gantry 6 performs the agitation operation by the agitator 7 while reciprocally reversing in the front-rear direction along the step portion 3a of the left and right side walls 3 of the decomposition treatment tank 2, but the gantry 6 Is temporarily stopped with the first and second stirrers 9 and 10 of the stirrer 7 approaching either one of the side walls 4 before and after the decomposition treatment tank 2 as the moving end of the reciprocating reversal movement. 7 is also configured to stop the stirring operation. Then, the stop state is continued for a preset waiting time, and then the movement direction is reversed, the rotation direction of the drive shaft 14 is reversed, and the movement in the decomposition treatment tank 2 is started while performing the stirring operation. It is configured as follows.
　そして、本実施の形態では、架台６が前記移動端に達したとき、撹拌装置７は分解処理槽２に形成された落とし込み凹部２０の第二後溝側辺２０ｄの直上に位置するように設定されている。そして、撹拌装置７が進行方向先側の作動チェーン１６（撹拌翼１６ａ）を下動（下方に移動）させながら前後何れかの側壁４側の移動端に近付づき（図５の仮想線は前側壁４側における撹拌装置７（第一、第二撹拌機９、１０）の移動端を示す）、第一、第二撹拌機９、１０が被撹拌物を側壁４に押し付けるような移動がなされると、被撹拌物が落とし込み凹部２０の第二後溝側辺２０ｄの傾斜面に沿って溝底辺２０ｂ（左右移送体２１）側に降下するように構成されており、これによって、被撹拌物が前後側壁４に押し付けられて付着、固化するようなことが防止されるように構成されている。
　さらに、第二後溝側辺２０ｄに沿って降下する被撹拌物は、ガイド突部２０ｅにより左右移送体ケーシング２１ａに開設された左右方向三箇所の開口２１ｄの何れかに誘導されて、ケーシング２１ａ内に落ち込んで排出、回収されるように構成されている。 And in this Embodiment, when the mount frame 6 reaches the said moving end, the stirring apparatus 7 is set so that it may be located just above the 2nd rear groove side 20d of the dropping recessed part 20 formed in the decomposition processing tank 2. FIG. Has been. Then, the stirring device 7 approaches the moving end on either the front or rear side wall 4 while moving the working chain 16 (stirring blade 16a) on the front side in the traveling direction downward (moving downward) (the phantom line in FIG. 5 indicates A movement such that the stirring device 7 on the front side wall 4 side (the moving end of the first and second stirrers 9 and 10), the first and second stirrers 9 and 10 press the object to be stirred against the side wall 4 is performed. If it is made, it will be comprised so that a to-be-stirred object may drop and it may fall to the groove bottom side 20b (left-right transfer body 21) side along the inclined surface of the 2nd back groove side 20d of the recessed part 20, and this An object is configured to be prevented from adhering and solidifying by being pressed against the front and rear side walls 4.
Further, the agitated object descending along the second rear groove side 20d is guided to one of the three openings 21d in the left-right direction opened in the left-right transfer body casing 21a by the guide protrusion 20e, and the casing 21a. It is configured to fall inside and be discharged and collected.
　そして、前記落とし込み凹部２０に落とし込まれた被撹拌物は、架台６が移動端に位置して停止する状態において、排出手段、回収手段である左右移送体２１、上方移送体２２を駆動することにより、シューター２２ｃを経由して散布装置８のケーシング１８内に移送されるように構成されている。このように、落とし込み凹部２０に落ち込んで外部に排出された被撹拌物は、回収物として散布装置８のケーシング１８内に移送され、ケーシング内に予め収容されている被処理物との混合物となって、架台６が反転移動を開始することに伴い、再びケーシング１８の散布口１８ｆから分解処理槽２内に散布されて分解処理されるように構成されている。因みに、落とし込み凹部２０に排出された被撹拌物は、予め散布装置８のケーシング１８内に投入される被処理物よりも脱水されて分解処理が進んだ状態のものとなっている。このため、ケーシング１８内の被処理物と回収物との混合物である内容物は、含水率が低下された状態となり、一層散布に適した状態になるばかりでなく、分解処理槽２内における分解性能が早まる（分解処理の促進が図れる）ように構成されている。 Then, the agitated object dropped into the drop recess 20 drives the left and right transfer bodies 21 and the upper transfer body 22 as the discharge means and the recovery means in a state where the gantry 6 is positioned at the moving end and stops. By this, it is configured to be transferred into the casing 18 of the spraying device 8 via the shooter 22c. In this way, the agitated object that has fallen into the dropping recess 20 and is discharged to the outside is transferred as a recovered material into the casing 18 of the spraying device 8 and becomes a mixture with the object to be treated that is previously stored in the casing. Thus, as the gantry 6 starts to reversely move, it is again sprayed from the spray port 18f of the casing 18 into the decomposition treatment tank 2 and decomposed. Incidentally, the object to be agitated discharged into the dropping recess 20 is in a state in which the object to be processed is dehydrated and decomposed more than the object to be treated previously introduced into the casing 18 of the spraying device 8. For this reason, the content which is a mixture of the to-be-processed object and collection | recovery material in the casing 18 will be in the state in which the moisture content fell, and not only will it be in the state suitable for spreading | diffusion, but also the decomposition | disassembly in the decomposition treatment tank 2 It is configured so that the performance is accelerated (the decomposition process can be promoted).
　叙述の如く構成された本形態において、架台６に搭載された撹拌装置７が分解処理槽２内を前後方向に往復反転移動することにより、分解処理槽２内の被処理物とコロニーとの混合物である被撹拌物が上下に切り返すような撹拌作動を受けて分解処理される。この場合に、架台６の往復反転移動の移動端において、被撹拌物は撹拌装置７の第一、第二撹拌機９、１０により前後側壁４に押し付けられるような圧力を受けるが、このとき、撹拌装置７の直下となる分解処理槽２の底壁５には落とし込み凹部２０が形成されていて、第一、第二撹拌機９、１０により前後側壁４に押し寄せられた被撹拌物が落とし込み凹部２０に落とし込まれて、前後側壁４に付着して固化するようなことが防止される。この結果、撹拌装置による長時間にわたる往復反転作動がなされたとしても、被処理物が前後側壁４に付着、固化して堆積（蓄積）するようなことがなく、しかも、分解処理槽２内における撹拌装置７の移動範囲を一定にすることができて、分解処理槽内の被撹拌物を全域に亘って流動性の良いさらさら状態に保持させて高い分解処理効率を維持することが可能となる。しかも、落とし込み凹部２０に落ち込んだ被撹拌物は外部に排出可能となっているので、落とし込み凹部２０に堆積、固化することはない。 In the present embodiment configured as described, the agitation device 7 mounted on the gantry 6 reciprocally moves in the front-rear direction in the decomposition treatment tank 2 so that the mixture of the object to be processed and the colonies in the decomposition treatment tank 2 is obtained. The object to be stirred is subjected to a stirring operation such that it is turned up and down and decomposed. In this case, at the moving end of the reciprocating reversal movement of the gantry 6, the object to be stirred is subjected to pressure that is pressed against the front and rear side walls 4 by the first and second stirrers 9 and 10 of the stirring device 7. A drop recess 20 is formed in the bottom wall 5 of the decomposition treatment tank 2 immediately below the stirring device 7, and the object to be stirred pushed by the first and second stirrers 9 and 10 to the front and rear side walls 4 is dropped into the recess. 20 is prevented from being attached to the front and rear side walls 4 and solidifying. As a result, even if the reciprocating reversal operation is performed for a long time by the stirring device, the object to be processed does not adhere to the front and rear side walls 4, solidify and accumulate (accumulate), and in the decomposition treatment tank 2. The moving range of the agitation device 7 can be made constant, and the substance to be agitated in the decomposition treatment tank can be maintained in a free flowing state with good fluidity over the entire region to maintain high decomposition treatment efficiency. . And since the to-be-stirred object which fell in the dropping recessed part 20 can be discharged | emitted outside, it does not accumulate and solidify in the dropping recessed part 20. FIG.
　このように、本発明が実施されたものにあっては、前後方向に往復反転移動する撹拌装置７に対して、分解処理槽２の前後端部に落とし込み凹部２０を形成して、前後側壁４に被撹拌物が付着、固化することがないようにしたものであるが、このものでは、落とし込み凹部２０を分解処理槽２内に形成し、撹拌装置７の往復反転移動の移動端が落とし込み凹部２０の直上に位置するように構成したので、被撹拌物に撹拌装置７による前後側壁４側への押し付け力が、被撹拌物を落とし込み凹部２０に誘導することになって、被撹拌物が確実に落とし込み凹部２０に回収されて、前後側壁４に付着、固化することを一層防止できる。 As described above, in the embodiment in which the present invention is implemented, the front and rear side walls 4 are formed by dropping into the front and rear end portions of the decomposition treatment tank 2 with respect to the stirring device 7 that reciprocates in the front-rear direction. In this case, the dropping recess 20 is formed in the decomposition treatment tank 2 and the moving end of the reciprocating reversal movement of the stirring device 7 is dropped into the recess. Since the configuration is such that the object to be stirred is pressed against the front and rear side walls 4 by the stirring device 7, the object to be stirred is dropped into the concave portion 20, so that the object to be stirred is surely secured. It is possible to further prevent the material from being collected in the recess 20 and attached to the front and rear side walls 4 and solidified.
　しかも、このものにおいて、落とし込み凹部２０には側壁４側ほど低位となる傾斜状の第二後溝側辺２０ｄが形成されているので、被撹拌物を落とし込み凹部２０側への誘導が確実で、被撹拌物を遅滞することなく落とし込み凹部２０に落とし込むことができ、被撹拌物の側壁４への付着、固化をさらに防止することができる。 In addition, in this, since the inclined second rear groove side 20d that is lower in the side wall 4 side is formed in the dropping recess 20, the object to be stirred is dropped and guided to the recess 20 side is reliable. The object to be stirred can be dropped into the dropping recess 20 without delay, and adhesion and solidification of the object to be stirred to the side wall 4 can be further prevented.
　さらにこのものでは、落とし込み凹部２０に落とし込まれた被撹拌物（回収物）を分解処理槽２の外部に排出する排出手段が設けられるとともに、該排出したものを回収物として散布装置８のケーシング１８に戻す回収手段が設けられており、回収物が再びケーシング１８を経由して分解処理槽２に散布される構成となっている。このため、落とし込み凹部２０に落とし込まれた被撹拌物を自動的に外部に排出することができるうえ、該落とし込み凹部２０に落とし込まれた被撹拌物が回収されてケーシング１８に戻されるので、ケーシング１８内の内容物（被処理物と回収物との混合物）の含水率が低減されて、内容物を散布に適した状態とすることが可能となるうえ、分解処理槽２内における分解処理を促進させることができるという利点もある。 Further, in this device, there is provided a discharge means for discharging the agitated object (recovered material) dropped into the dropping recess 20 to the outside of the decomposition treatment tank 2, and the discharged material is used as a recovered material for the casing of the spraying device 8. A recovery means for returning to 18 is provided, and the recovered material is again sprayed to the decomposition treatment tank 2 via the casing 18. For this reason, the agitated object dropped into the dropping recess 20 can be automatically discharged to the outside, and the agitated object dropped into the dropping recess 20 is recovered and returned to the casing 18. The moisture content of the contents in the casing 18 (mixture of the object to be treated and the recovered material) is reduced, and the contents can be made suitable for spraying, and the decomposition treatment in the decomposition treatment tank 2 is performed. There is also an advantage that can be promoted.

The stirring device 24 in the decomposition treatment tank 23 is configured to be positioned immediately above the dropping recess 25 when reaching the moving end in the reciprocating reversal movement close to the front and rear side walls 23b. When an object acts to press the object against the front and rear side walls 23 b, the object to be stirred drops into the recess 25. In this device, the agitated object dropped into the dropping recess 25 is spread through the first and second recovery means composed of the left and right transfer bodies 26, the upper transfer body 27, and the shooter provided on the groove bottom 25a. It is the structure similar to said 1st embodiment that it is comprised so that it may be transported and sprayed in the decomposition processing tank 23 again.
Even in this case, when the object to be stirred is pressed against the front and rear side walls 23b by the stirring device 24 that moves in the decomposition treatment tank 23, the object to be stirred that has received the pressure falls into the recess 25, thereby It is prevented from adhering and solidifying to 23b, and high decomposition efficiency can be maintained.
