する。 A conventional methane fermentation tank is as shown in FIG. 100 is a fermentation container, and 101 is a lid, which is fastened to the flange portion of the fermentation tank 100 with bolts or the like.
The lid 101 is provided with an input port 102 into which organic waste is input. 103 is a submersible pump that promotes methane fermentation by stirring the liquid in the tank, and its cable 104 passes through a water envelope 105 disposed on the lid 101 and communicates with the outside.
Reference numeral 106 denotes a gas outlet provided in the lid 101, which communicates with a gas tank (not shown) or the like. Reference numeral 107 denotes an overflow pipe disposed in the fermentation container 100 for discharging digestive juices.
従つて上記のような構成において、水中ポンプ
１０３が異物等のかみ込みによりロツク等の異常
が生じ修理が必要となつたり、あるいは定期的に
保守をしようとする場合、次のような欠点をもつ
ている。 Therefore, in the above-mentioned configuration, if the submersible pump 103 becomes locked due to foreign matter or the like and repairs are required, or if regular maintenance is to be performed, the following disadvantages arise: ing.
１ 水中ポンプ１０３を引き出すためには、蓋１
０１を取り外さなければならず、蓋自体が大き
いこと、又発酵容器１００との締結箇所が多い
ため、蓋１０１の取り外し、取り付けが非常に
面倒である。1 To pull out the submersible pump 103, open the lid 1.
01 has to be removed, the lid itself is large, and there are many fastening points to the fermentation container 100, so it is very troublesome to remove and install the lid 101.
２ 水中ポンプ１０３を再び発酵容器１００にも
どす時、容器内の液が混濁していて中が見えな
いため、決められた位置に設置することが困難
である。2. When putting the submersible pump 103 back into the fermentation container 100, it is difficult to install it in a predetermined position because the liquid inside the container is cloudy and the inside cannot be seen.
３ 再度蓋１０１を取り付けた後は、空間部１０
８は空気で満されている。従つてメタン菌の活
動に悪影響を及ぼすか、あるいは発生するガス

きくなればなるほど、多量の置換ガスを必要と
し、経費がかさむ。3 After attaching the lid 101 again, the space 10
8 is filled with air. Therefore, if the activity of methane bacteria is adversely affected, or if the generated gas is to be used effectively, air is mixed into the gas, which not only temporarily becomes a poor quality gas but also becomes dangerous. It turns out. To prevent this, the space 107 must be replaced with a gas that does not contain oxygen, and the larger the fermentation vessel 100 is, the more replacement gas is required and the cost increases.
本発明は上記従来の欠点を解消するもので、以
下第２図にもとづいてその一実施例について説明
する。 The present invention solves the above-mentioned conventional drawbacks, and one embodiment thereof will be described below based on FIG. 2.

のケーブルで、蓋７のかん通部で気密性のパツキ
ン（図示せず）を介して外部電源に通じている。
１３は発酵容器１に配設された溢水管である。 Reference numeral 1 denotes a fermentation container, the upper part of which is connected to a lid 2 at an outer peripheral flange. 3 is an inlet, and 4 is located at the upper part of a submersible pump 5, which serves as an outlet for the submersible pump and whose lower end is submerged in the liquid in the fermentation container 1.
Reference numeral 6 denotes a gas outlet, which is arranged in the lid 2 together with the inlet 3 and the water envelope 4. Reference numeral 7 denotes a lid that seals the outlet of the water envelope 4, and a gas outlet 6' and a latch 9 for a lifting chain 8 of the submersible pump 5 are provided. 10 is a float for detecting the water level provided inside the water envelope 4, and 11 and 12 are cables for a submersible pump and the float, respectively, which are connected to an external power source through an airtight gasket (not shown) at the passage part of the lid 7. I understand.
13 is an overflow pipe arranged in the fermentation container 1.
上記構成において動作を簡単に説明すると、投
入口３より投入された有機性廃棄物は、発酵容器
１内で水中ポンプ５により撹拌され、反応が促進
されてガスと水に分解される。ガスはガス取出口
６及び６′より取出され、外部のガスタンク等に
貯えられ、有効利用される。水は、そのつど溢水
管１３より排水される。フロート１０は溢水管１
３が何らかの原因でつまり異常に水位が上がつた
場合、警報をならす水位センサーである。 To briefly explain the operation of the above configuration, organic waste input through the input port 3 is stirred in the fermentation container 1 by the submersible pump 5, and the reaction is promoted to be decomposed into gas and water. The gas is taken out from the gas take-off ports 6 and 6', stored in an external gas tank, etc., and used effectively. The water is drained from the overflow pipe 13 each time. Float 10 is overflow pipe 1
3 is a water level sensor that sounds an alarm if the water level rises abnormally for some reason.
上記構成をとることにより従来の欠点を解消し
次のような効果を発揮する。 By adopting the above configuration, the drawbacks of the conventional system are eliminated and the following effects are achieved.
１ 水中ポンプ５が異物等によりロツク等の異常
が生じた場合、水中ポンプ５は蓋７を取り外す
ことにより引き上げられる。この時蓋７は蓋２
に対して小さなものであるため取り外しが容易
である。1. If an abnormality such as locking occurs in the submersible pump 5 due to foreign matter or the like, the submersible pump 5 can be lifted up by removing the lid 7. At this time, lid 7 is lid 2
It is easy to remove because it is small.
２ 水中ポンプ５の引き上げ及び設置の際、水封
筒４は、ガイドの役割を果し特に設置の際には
所定の位置に容易に水中ポンプを持つていくこ
とができスムーズな作業ができる。2. When lifting and installing the submersible pump 5, the water envelope 4 plays the role of a guide, and especially during installation, the submersible pump can be easily carried to a predetermined position, allowing smooth work.
３ 水封筒４を水中ポンプ５の上部までのばした
場合は、起動時の回わり止めにも利用できる。3. If the water envelope 4 is extended to the top of the submersible pump 5, it can also be used to prevent rotation during startup.
４ 水中ポンプ５を元にもどし、蓋７を取り付け
た後、空間部１５は空気に置きかわつている。
ここで水封筒４の空間部１５の容積が、発酵槽
全体の空間部１４の容積に対して、ある程度小
さければ、空気のメタン菌の活動に対する影響
あるいは、ガス成分に対する影響は無視できる
ものとなり、空間部１５はガス置換を行なわな
くてもよい。逆に空間部１５の容積が空間部１
４の容積に対して無視できない程であれば、ガ
ス置換しなければならないが、必要とする置換
ガス量は空間部１５の容積の箇所だけでよいか
ら従来例より少量ですみ、経費も節減できる。4 After returning the submersible pump 5 and attaching the lid 7, the space 15 is replaced with air.
Here, if the volume of the space 15 of the water envelope 4 is smaller than the volume of the space 14 of the whole fermenter, the effect on the activity of the methane bacteria in the air or the effect on the gas components will be negligible. The space 15 does not need to be replaced with gas. Conversely, the volume of the space 15 is the space 1
If the volume of space 15 is not negligible, gas must be replaced, but since the amount of replacement gas required is only at the volume of space 15, it is smaller than the conventional example, and costs can be reduced. .
このように本発明によれば、水封筒を設けるこ
とにより、水中ポンプのメンテナンスの容易さ、
経費節減、構成の簡素化に多大な効果を発揮する
ものである。 According to the present invention, by providing the water envelope, maintenance of the submersible pump is facilitated,
This is highly effective in reducing costs and simplifying the configuration.
