Description

本考案は汚泥等有機性廃棄物を醗酵により堆肥化する装置である。 The present invention is an apparatus for composting organic waste such as sludge by fermentation.

下水の終末処理場、又は農業集落排水処理場などでは活性、浄化とうの処理槽に沈殿した未処理汚泥を凝縮して水分を少なくして、埋め立て、焼却とうの処理をしています。近年この沈殿した汚泥を醗酵槽に入れ、醗酵堆肥化することが広まってきました。
またこの問題を解決するために醗酵槽を大きくしなければ成りませんでした。In the final treatment plant of sewage or the agricultural settlement wastewater treatment plant, the untreated sludge settled in the treatment tank for active and purification treatment is condensed to reduce the water, and landfill and incineration are processed. In recent years, it has become widespread to put this precipitated sludge into a fermenter and ferment compost.
In order to solve this problem, the fermenter had to be enlarged.

従来有機性廃棄物の醗酵処理には１槽式醗酵槽で処理を行っておりましたが連日、未処理の廃棄物を投入する場合、短時間に醗酵済みの処理物のみを純粋に取り出すことは不可能でした。
有機性廃棄物の醗酵は長時間を有するため処理槽を極端に大きくするか、醗酵と称しても乾燥に偏り、完熟していない状態で処理している傾向がありました。
この完熟していない処理物は水を与えると元の状態に戻ってしまう場合が多くあります。Conventionally, fermenting treatment of organic waste has been carried out in a single tank fermenter. However, when untreated waste is introduced every day, only the fermented treated product should be taken out in a short time. Was impossible.
Fermentation of organic waste has a long time, so the treatment tank is extremely large, or even if it is called fermentation, it tends to dry and tend to be processed in an incomplete state.
In many cases, this unripe product will return to its original state when given water.

課題を解決するための手段１Means 1 for solving the problem

上記目的を達成するため、処理槽を２槽に分離して、１次醗酵槽１で１次醗酵、２次醗酵槽２で２次醗酵まで持っていくことにより、最終的に醗酵を完熟させることが出来、取り出した醗酵物に未熟な醗酵物が混入されることを防ぎます。 In order to achieve the above object, the treatment tank is separated into two tanks, and finally the fermentation is completed by bringing the primary fermentation tank 1 to the primary fermentation and the secondary fermentation tank 2 to the secondary fermentation. Can prevent immature fermentation from being mixed into the extracted fermentation product.

図を持って説明いたします。
図１は一次醗酵のための醗酵槽１に投入口２を設け、内部に撹拌羽３及び熱風吹き出し口４を設ける。I will explain with a diagram.
In FIG. 1, a fermenter 1 for primary fermentation is provided with an inlet 2, and a stirring blade 3 and a hot air outlet 4 are provided inside.

１次醗酵槽１の投入口２より、有機性廃棄物５を投入します。
この処理物の初期の重量は８５％程度の水分量を含んでいますが、時間の経過とともに、内部の撹拌羽２の撹拌と熱風吹き出し口４の加熱により水分が飛び、重量が軽くなります。この間、軽度な醗酵も進みますので醗酵熱も加わります。The organic waste 5 is introduced from the inlet 2 of the primary fermentation tank 1.
The initial weight of this processed material contains about 85% of water, but as time goes by, the water is released by the stirring of the internal stirring blade 2 and the heating of the hot air outlet 4 and the weight is reduced. . During this time, mild fermentation progresses, so fermentation heat is also added.

装置の下部に重量計６を設け、１次醗酵槽の予定された醗酵状態の完了を検知して、１次醗酵槽の処理を終了して１次槽排出口８を開口して２次醗酵槽の投入口９を開けて１次槽醗酵物１０を２次醗酵槽２に移行します。
１次醗酵槽を終えた処理物の醗酵は未成熟の状態で取り出しますが水分の減少した分、重量も容積も減量します。A weighing scale 6 is provided in the lower part of the apparatus, the completion of the scheduled fermentation state of the primary fermentation tank is detected, the processing of the primary fermentation tank is terminated, the primary tank outlet 8 is opened, and the secondary fermentation is performed. The tank inlet 9 is opened and the primary tank fermentation product 10 is transferred to the secondary fermentation tank 2.
Fermentation of the processed product that has finished the primary fermenter is taken out in an immature state, but the weight and volume are reduced by the reduced water content.

２次醗酵槽２への移行分は容積にして１０％程度に減容していますので、２次醗酵槽２は、１次醗酵槽１と同容積でも１０倍の収容能力があります。
２次醗酵槽２も醗酵の進展に従い減容していきますので、５０％の減容でも、１次醗酵槽への投入量の２０倍の収容能力を持ちます。従って、２次醗酵槽２は１次醗酵槽１の投入量の２０倍の収容力が有ることで、１槽式の醗酵処理に比べ２０倍の長時間を掛けて十分な醗酵処理が出来る訳です。Since the volume transferred to the secondary fermentation tank 2 is reduced to about 10% in volume, the secondary fermentation tank 2 has 10 times the capacity of the primary fermentation tank 1 even in the same volume.
The secondary fermenter 2 will also be reduced in volume as the fermentation progresses, so even a 50% reduction in capacity will have 20 times the capacity of the input to the primary fermenter. Therefore, the secondary fermenter 2 has a capacity 20 times that of the input of the primary fermenter 1 and can be sufficiently fermented over 20 times longer than the fermenter of the single tank type. is.

２次醗酵槽も１次醗酵槽と同様に撹拌、加熱を行い、成熟するまでの時間を掛けた後、重量計１１の換算により完了を検知いたします。
完熟した処理物は排出口１２を開くことにより外部に排出されます。The secondary fermenter is stirred and heated in the same way as the primary fermenter, and after completion of the time until it matures, the completion is detected by the conversion of the scale 11.
The fully processed product is discharged to the outside by opening the outlet 12.

課題を解決するための手段２Means 2 for solving the problem

１次醗酵槽１と２次醗酵槽２とを段違いに設置して、１次醗酵槽１の排出口７の下側に２次醗酵槽２の投入口９が来るように配置します。
これにより１次醗酵槽１と２次醗酵槽２との間にコンベアーとうの移送機器が不用になり、装置の設置面積も少なくなります。The primary fermenter 1 and the secondary fermenter 2 are installed in different stages and arranged so that the inlet 9 of the secondary fermenter 2 comes below the outlet 7 of the primary fermenter 1.
This eliminates the need for a conveyor-type transfer device between the primary fermenter 1 and the secondary fermenter 2 and reduces the installation area of the device.

考案の効果Effect of device

１槽式醗酵槽に比べ２槽式醗酵槽は１次醗酵槽の投入物の完熟まで待つ必要もなく醗酵途中の処理物を２次槽へ排出できるので、新たな有機性廃棄物の投入できる間隔を短くすることが出来、また２次醗酵槽より排出される処理物の醗酵を未熟な醗酵物の混入を防ぎ，全てを完熟したものにすることが出来ます。 Compared with the 1 tank type fermenter, the 2 tank type fermenter does not need to wait until the input of the primary fermenter is fully matured, so that the processed product during the fermentation can be discharged to the secondary tank, so that new organic waste can be input. The interval can be shortened, and the fermentation of the processed product discharged from the secondary fermenter can prevent the mixing of immature fermented products and make everything completely ripe.

図１の如く、醗酵処理第１槽の排出口に第２槽の投入口を近接させ、段違いに醗酵槽が並ぶ形態を持った考案です。 As shown in Fig. 1, the second tank inlet is close to the outlet of the first fermentation treatment tank, and the fermentation tanks are arranged in stages.
