It is.

特に、春先から夏にかけて、海洋にはクラゲが大量発生し、群れて行動する為、漁業関係者は魚と一緒に大量に混獲されたクラゲを回収して廃棄処理しなければならなかったし、また、海水を冷却水等として利用する発電所や工場などは、取水口付近に押し寄せるクラゲを回収し廃棄処理するなど大きな被害をもたらされている。  In particular, from the early spring to the summer, jellyfish are produced in large quantities in the ocean and behave in groups, so fishermen had to collect and dispose of jellyfish caught in large quantities with fish, In addition, power plants and factories that use seawater as cooling water, etc., have caused great damage, such as collecting and disposing of jellyfish that rush near the intake.

近年、クラゲの廃棄処理に当たっては臭気などの環境問題から埋め立て場所の確保が非常に困難になっている。さらに、埋め立て地まで運搬しなければならないため処理に時間と手間がかかる上、経済的負担も非常に大きい。そのため、ぶよぶよした生鮮クラゲの体形を形造っている９５〜９７％の水分を除去した後クラゲを廃棄処理することが要望されている。  In recent years, in the disposal of jellyfish, it has become very difficult to secure a landfill site due to environmental problems such as odor. Furthermore, since it must be transported to the landfill site, processing takes time and labor, and the economic burden is very large. Therefore, it is desired to dispose of the jellyfish after removing 95 to 97% of the water forming the body shape of the fresh jellyfish.

その１つとして、特許文献１に廃棄処理に当たって、カツターでクラゲを切片状に切り刻み、これを８５〜９０℃の清温水中に浸漬して減容化を図った後、廃棄処理する方法が記述されているが、この場合８５〜９０℃の清水を維持する加熱装置が必要な上、これを維持するのに膨大な費用がかかり、廃棄するだけでこのような経費はかけられず実用面で難しかった。  As one of them, Patent Document 1 describes a method of disposing of waste after cutting the jellyfish into slices with a cutter and immersing it in 85-90 ° C. warm water to reduce the volume. However, in this case, a heating device that maintains fresh water at 85 to 90 ° C. is necessary, and it takes an enormous amount of money to maintain the heating device. It was.

もうひとつの方法として、特許文献２にミキサーを使ってクラゲの水分と固形分を分離して減容化する方法が記述されているが、破砕した後の懸濁水に凝集剤を使用しなければならず、これもまた膨大な費用と手間がかかり実用面で難しい問題があった。
特開平５−３７６９号公報 特開平４−４８９８６号公報 As another method, Patent Document 2 describes a method of reducing the volume of jellyfish by separating the water and solid content using a mixer. However, if a flocculant is not used in the suspended water after crushing In addition, this also has a huge problem in terms of practical use because of its huge cost and labor.
JP-A-5-3769 Japanese Patent Laid-Open No. 4-48986

(2) Furthermore, the processed wood chips can be reused and are an inexpensive processing method that is suitable for recycling.

発明の実施するための最良の形態BEST MODE FOR CARRYING OUT THE INVENTION

以下本発明に係るクラゲの脱水処理装置の一実施例を図面に基づいて説明する。
（実施形態）
１は端部２、３と側壁４、５と底部６とから構成された処理槽で、処理槽１上部は原料の投入口７となっている。さらに、処理槽１の中央部には、投入口７より投入された原料を混練するパドルミキサー８と、その下部に混練物を加圧したり、排出したりするリボンスクリュー９とがそれぞれ配置されている。そして、パドルミキサー８は、減速機付電動機１０のチエーン駆動により正逆回転出来るようになっている。また、リボンスクリュー９も減速機付電動機１１のチエーン駆動により正逆回転出来るようになっている。処理槽１の底部６には、排出路１２が形成されると共に排出路１２に連通した排出口１３が設けられている。１４は処理槽１を支持する支柱、１５はクラゲや木チップを処理槽１に投入するバケットで、このバケット１５は、クレーントラックなどの適宜手段により持ち上げられ、投入口７より処理槽１に投入されるようになっている。
木チップは、製紙原料として鱗片状に削りとられたもので、鋭利な刃状と粗目を有している。 An embodiment of a jellyfish dehydration apparatus according to the present invention will be described below with reference to the drawings.
(Embodiment)
Reference numeral 1 denotes a treatment tank composed of end portions 2 and 3, side walls 4 and 5, and a bottom portion 6, and an upper portion of the treatment tank 1 serves as a material inlet 7. Further, a paddle mixer 8 for kneading the raw material charged from the inlet 7 and a ribbon screw 9 for pressurizing and discharging the kneaded material are disposed at the center of the processing tank 1. Yes. The paddle mixer 8 can be rotated forward and backward by the chain drive of the motor 10 with speed reducer. The ribbon screw 9 can also be rotated forward and backward by chain drive of the motor 11 with a speed reducer. A discharge path 12 is formed at the bottom 6 of the treatment tank 1 and a discharge port 13 communicating with the discharge path 12 is provided. Reference numeral 14 denotes a support column that supports the treatment tank 1, and 15 denotes a bucket that throws jellyfish or wood chips into the treatment tank 1. The bucket 15 is lifted by appropriate means such as a crane truck and is thrown into the treatment tank 1 from the inlet 7. It has come to be.
Wood chips are scraped off as a papermaking raw material and have sharp edges and coarse texture.

（作用）
以上のように構成されたクラゲの脱水処理装置は次のように作用する。
まず、バケット１５で回収されたクラゲと木チップとをそれぞれ投入口７から処理槽１に投入される。投入されたクラゲと木チップは減速機付電動機１０のチエーン駆動により回転するパドルミキサー８により混練物に混練される。混練された混練物は同時に減速機付電動機１１のチエーン駆動により回転するリボンスクリュー９へ落下する。落下した混練物は減速機付電動機１１のチエーン駆動により回転するリボンスクリュー９により、処理槽１の端部２へ押し付けられ加圧される。そして、この時、加圧された混練物は盛り上がりパドルミキサー８に戻される。この動作を数回繰り返すことにより、均一な混練物にされる。均一な混練物になった時点で、次にリボンスクリュー９を逆回転させる。リボンスクリュー９を、数回、正逆回転することによって、木チップの鋭利な刃状と粗目を利用してクラゲの組織を切断破砕して、クラゲと木チップとの混練物のクラゲの流動性を高め、木質の適度の強度と吸収性の少なさを利用して、生成物中に水分の逃路を作って脱水し易くするものである。言いかえれば、山中から湧出する岩清水のように、各木片毎に周辺に搾出されてできた水分は連携しながら水路を作って外部に排出される。 (Function)
The jellyfish dehydration apparatus configured as described above operates as follows.
First, the jellyfish and wood chips collected in the bucket 15 are respectively charged into the treatment tank 1 from the charging port 7. The introduced jellyfish and wood chips are kneaded into the kneaded product by the paddle mixer 8 that is rotated by the chain drive of the motor 10 with a reduction gear. The kneaded product is simultaneously dropped onto the ribbon screw 9 that is rotated by the chain drive of the motor 11 with speed reducer. The fallen kneaded material is pressed against the end 2 of the processing tank 1 and pressurized by the ribbon screw 9 that is rotated by the chain drive of the motor 11 with speed reducer. At this time, the pressurized kneaded product is returned to the raised paddle mixer 8. By repeating this operation several times, a uniform kneaded product is obtained. When a uniform kneaded product is obtained, the ribbon screw 9 is then rotated backward. The ribbon screw 9 is rotated forward and backward several times to cut and crush the jellyfish tissue using the sharp edges and coarseness of the wood chips, and the fluidity of the jellyfish in the mixture of jellyfish and wood chips It makes use of the moderate strength and low absorbency of wood to create a water escape in the product to facilitate dehydration. In other words, like Iwashimizu springing from the middle of the mountain, the water that is squeezed out to the periphery for each piece of wood forms a waterway and is discharged outside.

したがって、クラゲをそのまま処分するのに比べて、大幅に減容化できるとともに、クラゲの水分をほとんど脱水させて軽量化がはかれ、その後の取り扱いや搬送、埋め立てなどの廃棄処理作業を極めて容易に行なうことができるものである。そして、脱水された水分は排出路１２を通って排出口１３から排出される。脱水された水分が排出され終わった後、殆どが木チップのみとなった残物が排出口１３から排出される。この木チップの残物は新たなクラゲと混練して再利用が可能である。  Therefore, the volume of the jellyfish can be reduced significantly compared to the case of disposing of the jellyfish as it is, and the weight of the jellyfish can be reduced by dehydrating it. It can be done. The dehydrated water is discharged from the discharge port 13 through the discharge path 12. After the dehydrated moisture has been discharged, the residue that is mostly made of wood chips is discharged from the discharge port 13. The wood chip residue can be reused by kneading with new jellyfish.

以下本発明の好適な実施例を述べる。
木チップ１袋３００〜５００ｋｇ（約１立方メートル）をクラゲの脱水処理装置の処理槽１内に入れ、次に生鮮クラゲ約１ｔを投入する。そして減速機付電動機１０、１１を駆動してパドルミキサー８とリボンスクリュー９を回転する。１回目の加圧混練を１５分間運転する。次に１０分休止し分離した水分を排出口１３より排出する。排出終了後、２回目の生鮮クラゲ約１ｔを投入し、再度１５分間運転する。この運転作動によって約８５％〜９０％の水分を直接排出除去することが出来た。形骸的には殆ど脱水状態となり、その後パレット上に混合物を受け、１日放置後検視したところ、約９５％の脱水を得ることができた。Preferred embodiments of the present invention will be described below.
One 300-500 kg (about 1 cubic meter) of wood chip bag is put into the treatment tank 1 of the jellyfish dewatering apparatus, and then about 1 t of fresh jellyfish is added. Then, the motors 10 and 11 with speed reducers are driven to rotate the paddle mixer 8 and the ribbon screw 9. The first pressure kneading is operated for 15 minutes. Next, it is paused for 10 minutes and the separated water is discharged from the discharge port 13. After the end of the discharge, about 1 t of fresh jellyfish for the second time is added, and the operation is continued for 15 minutes. By this operation, about 85% to 90% of water was directly discharged and removed. The shape was almost dehydrated. After that, the mixture was placed on a pallet and left to stand for 1 day. After inspection, about 95% dehydration was obtained.

尚、上記実施形態は１実施例を述べただけで、種々変更しても何ら本発明の要旨を変更するものではない。  In addition, the said embodiment only described one Example, Even if it changes variously, it does not change the summary of this invention at all.
