Field of the Invention The present invention relates to a water draining device for draining only water (sludge water) in a sludge tank in which a material to be treated is stored to dehydrate the material to be treated. The water content in the sludge tank (fermentation tank) and the water that has undergone active decomposition are discharged to the outside of the tank, and the sludge inside the tank is not blocked at the inlet and inside of the draining device attached to the tank so that drainage efficiency does not decline. The present invention relates to a devised sludge tank drainer.

【従来の技術】近年、ゴミの排出量が激増して最終処分
場のスペースも限界に達している状況にあって、ゴミの
減量化が死活問題となっている。2. Description of the Related Art In recent years, the amount of waste has dramatically increased and the space at the final disposal site has reached its limit, so reducing the amount of waste has become a vital issue.
【０００４】特に、生ゴミは多量の水分を含み、また悪
臭を伴うこともあり、運搬や廃棄に苦慮している実状に
ある。[0004] In particular, food waste contains a large amount of water and may be accompanied by a bad odor, and it is difficult to carry and dispose of it.
【０００５】従来、そういった生ゴミの悪臭を抑制し且
つその減容化を図るための装置として、図５に示すよう
な生ゴミ処理装置が実用化されている。Conventionally, as a device for suppressing such a bad smell of raw garbage and for reducing the volume thereof, a raw garbage processing apparatus as shown in FIG. 5 has been put into practical use.

る。As shown in the figure, in this food waste processing apparatus, a sealed main body 1 is divided by partition plates 2, ..., And sludge tanks 3a, 3b, 3c, 3d are formed side by side. .
Further, a rotary shaft 5 rotated by a motor 4 penetrates each tank, and blades 6, ... Are fixed to the rotary shaft 5.
【０００７】一方、各槽の上方には送風ダクト７を敷設
し、送風機８から当該送風ダクト７を介して各槽に温風
を送り込めるようにしている。On the other hand, a blower duct 7 is laid above each tank so that warm air can be sent from the blower 8 to each tank through the blower duct 7.

燥させるようにしている。According to this food waste processing apparatus, the opening / closing lid 9 of the main body 1 is opened, and an object to be processed such as food waste is put into the sludge tank 3a and stirred by the blades 6, .... While gradually conveying to the sludge tank 3d, the air duct 7
The object to be treated (garbage) is drained and dried by the hot air blown from.
【０００９】しかし、この生ゴミ処理装置は投入される

が屑などの床材や乾燥剤を添加して水分調整を行ってい
るが、それでも被処理物の水抜き・乾燥が思うように進
まず処理に４５〜９０日程度を要しているというのが実
状である。However, since the water content of the food waste to be treated is very high in this food waste processing apparatus, the water content is adjusted by adding a floor material such as sawdust or a desiccant. However, the actual condition is that it takes 45 to 90 days for the treatment without draining and drying the treated material as expected.

ものの、被処理物の全体量が床材や乾燥剤の分だけ増大
するため、処理後における被処理物を最大でも３０分の
１程度にしか減容することができないという欠点があ
る。When the floor material and the desiccant are added, the water content of the treated material such as raw garbage can be made suitable for draining, but the total amount of the treated material is increased by the amount of the floor material and the desiccant. Therefore, there is a drawback in that the volume of the object to be treated after the treatment can be reduced to only about 1/30 at the maximum.
【００１１】一方、上記欠点を改良した生ゴミ処理装置
である発酵装置が本願出願人により、特願平６ー２００
７６６号にて開示された。On the other hand, a fermentation apparatus, which is an apparatus for treating food waste, which has improved the above-mentioned drawbacks, was filed by the applicant of the present invention in Japanese Patent Application No. 6-200.
No. 766.
【００１２】この発酵装置によれば、先ず脱水装置が被
処理物を菌の活動しやすい含水率６５％前後に脱水し、
しかる後発酵槽に落下させる。According to this fermenter, first, the dehydrator dehydrates the material to be treated to a water content of about 65% in which bacteria can easily act,
Then drop it into the fermenter.

て槽外へ排出し始める。Next, the raw garbage of the object to be treated which has fallen into the fermenter is heated to 50 to 60 ° C. by the heater and the warm air blown from the blower duct while being stirred by the blade, and under aerobic conditions. Fermentation and active decomposition of water is started to be discharged out of the tank by the drainer.

て徐々に次段の汚泥槽へ送り込まれるようになる。Then, while stirring and heating are continued, water removal and drying of the object to be processed are promoted, and eventually the object to be processed has a water content of 4%.
It becomes 5 to 55%, and from this point, the object to be treated is gradually fed into the next stage sludge tank by the blade.

Furthermore, it is agitated by blades that are rotated forward and backward intermittently, and at the same time is heated to 60 to 70 ° C by hot air and a heater, drainage and drying are further promoted, and eventually the water content becomes 30%. Before and after, the object to be processed is 150 ~
The volume will be reduced to about 1/200.
【００１６】一方、生ゴミ処理装置内の雰囲気は、排気
用の送風機にて吸引され脱臭槽へ送り込まれて脱臭処理
され、その後に外部に排出されるという構造である。On the other hand, the atmosphere in the garbage processing apparatus has a structure in which it is sucked by an air blower for exhaust, sent to a deodorizing tank for deodorizing treatment, and then discharged to the outside.
【００１７】[0017]
【発明が解決しようとする課題】しかしながら、生ゴミ
が発酵しやすい状態の含水率は前述のように６５％程度
であるが、上記発酵装置の脱水装置では７５〜８０％程
度にしか脱水されず、発酵条件を最適にすることが困難
であることが判った。However, although the water content in the state in which raw garbage is easily fermented is about 65% as described above, the dehydrator of the above-mentioned fermentation apparatus dehydrates only about 75-80%. It turned out that it is difficult to optimize the fermentation conditions.

う問題点があった。Therefore, although a method other than draining with a drying or dehydrating apparatus is applied, generally, the objects to be treated (sludge with a high water content, not limited to raw garbage) stored in the tank are drained. It is conceivable that a normal drainage outlet through a mesh filter will be installed on the outer wall of the tank (bottom or side surface of the tank) to discharge only water out of the tank. However, simply providing a drainage outlet will result in sludge inside the tank. However, there was a problem in that the drainage port was blocked by clogging the inner wall of the discharge port or the mesh filter and the desired drainage was not achieved.

まうという問題があった。In order to solve the above problems, the applicant of the present application attaches a stirring blade 13 to the tip of a rotary shaft 12 inserted in a substantially cylindrical housing 11 as shown in FIG. Only the sludge water in the tank (outer wall 15) is discharged through the discharge port 16 through the gap δ of about 0.5 mm, and the rotary shaft 12 is slowly rotated by a gear motor (not shown) to the vicinity of the gap inlet M by the stirring blade 13. A water draining device 10 having means for agitating so as not to attach sludge was devised, and in this case as well, sludge is attached to the peripheral surface of the rotating shaft in the gap δ and the inner wall reaching the discharge port 16 inside the housing 11 to prevent the sludge from sticking. There is a problem that clogging occurs and drainage efficiency decreases.

記汚泥水のみが排出される。According to the sludge tank water draining device of the present invention, a set of substantially cylindrical housings externally fixed in accordance with the circular holes formed in the outer wall of the sludge tank and a rotary shaft inserted in the housing inner circle are provided. Since the gap is 0.2 to 1 mm, the sludge water containing small sludge of this size or less passes through the gap due to the capillarity, so most of the objects to be treated remain in the tank and only the sludge water is discharged.
【００２４】汚泥槽内の水抜き装置が配設された近傍は

口から排水される。Further, the sludge clogging in the gap and in the vicinity of the sludge tank side inlet of the gap is a sludge discharging rotation which is mounted by sandwiching an elastic member on a rotating shaft which rotates at a speed of about 18 rotations per minute by a gear motor. The blade is swept immediately, and is fixed in a state of being biased and supported by the housing by an elastic member so that the tip of the blade opposes the rotating shaft and contacts the circumferential surface of the rotating shaft, and the sludge discharging rotating blade and the tip. Since the scraped sludge is crushed by the sludge scraping fixed blades that come into sliding contact with each other every rotation, the clearance is not clogged, and the sludge is always efficiently discharged through the clearance through the discharge port.
【００２６】上記弾性部材はスラッジ排出用回転羽根と

によって掻き落とされる。Further, the fine sludge adhering to the inner wall connected to the discharge port inside the housing after passing through the gap has the second rotary vane for sludge discharge mounted with the elastic member sandwiched between the rotary shafts to slide on the inner wall of the housing. It is scraped off by rotating while touching.
