Description
（０００１） (0001)
本考案は汚水処理場の浄化槽に沈殿堆積する浄化処理後の活性汚泥に含まれる 水分を除去する汚泥脱水機に関する。 （０００２） The present invention relates to a sludge dewatering machine that removes water contained in activated sludge after purification treatment that is deposited and accumulated in a septic tank of a wastewater treatment plant. (0002)
従来、活性汚泥の脱水機としては遠心分離による脱水機や、炉布の間に汚泥を 挾み油圧や空気圧でプレスするフェルダープレスや、連続的に汚泥を挾んだベル トをローラでプレスするベルトフィーダと呼ばれる脱水機があった。 （０００３） Conventionally, as a dehydrator for activated sludge, a dehydrator by centrifugal separation, a felder press that presses sludge between furnace cloths and presses it with hydraulic pressure or air pressure, and a belt that continuously presses sludge with rollers is used. There was a dehydrator called a belt feeder. (0003)
遠心分離による脱水機は大型であるため、充分に回転速度を上げることが難し く、通常２０００Ｒ．Ｐ．Ｍ．の回転速度で含水率を８５％位までしか脱水でき ず、脱水率が低い欠点がある。 （０００４） ローラによるプレスを用いたベルトフィーダもまた含水率が８５％位までしか 絞れず、脱水率が低い。 （０００５） 油圧、空気圧を用いたプレスは含水率が６５％位まで絞れるが、脱水処理後の ケーキと呼ばれる汚物が炉布から離れにくいため、炉布が目詰まりしやすいので 、頻繁に炉布を洗浄しなければならなくて、作業能率が悪い欠点がある。 （０００６） プレスタイプの脱水機は汚泥の中に石等の硬い固形異物が混入している場合、 この異物がプレスの妨げとなって充分に脱水できない欠点がある。 （０００７） よって従来の汚泥脱水作業は、まず、遠心分離による脱水機やベルトフィーダ による脱水で含水率を８５％位まで絞り、次にフェルダプレス油圧や空気圧によ って６５％位まで絞る２段階脱水をしていた。 （０００８） Since the spin-drying dehydrator is large, it is difficult to increase the rotation speed sufficiently, and it is usually 2000R. P. M. There is a drawback that the dehydration rate is low because the water content can be dehydrated only up to about 85% at the above rotation speed. A belt feeder using a roller press also has a low water content of only 85% and a low dehydration rate. (0005) A press using hydraulic pressure or air pressure can squeeze the water content up to about 65%, but since the sewage called cake after dewatering is difficult to separate from the kiln cloth, the kiln cloth is easily clogged. Has to be washed, which is a drawback of poor work efficiency. (0006) The press type dehydrator has a drawback that when hard solid foreign matter such as stones is mixed in sludge, the foreign matter interferes with pressing and cannot be sufficiently dehydrated. (0007) Therefore, in the conventional sludge dewatering work, first, the water content is reduced to about 85% by dewatering with a centrifuge or a belt feeder, and then down to about 65% with Felder press hydraulic pressure or air pressure. I was doing stage dehydration. (0008)
本考案の第１の目的は、１台の脱水機で遠心脱水とプレス脱水を同時または連 続して容易に行なえるコンパクトで効率の良い汚泥脱水機を提供することである 。 （０００９） 本考案の第２の目的は、汚泥中に石等の固形異物が混入していても充分な脱水 が行なえる汚泥脱水機を提供することである。 （００１０） 本考案の更に第３の目的は、炉布に付着した脱水後の汚物を容易に剥離除去で きる、炉布の洗浄の必要のない、メンテナンスの容易な汚泥脱水機を提供するこ とである。 （００１１） A first object of the present invention is to provide a compact and efficient sludge dewatering machine which can easily perform centrifugal dewatering and press dewatering simultaneously or continuously by one dewatering machine. (0009) A second object of the present invention is to provide a sludge dewatering machine that can perform sufficient dewatering even if solid foreign matter such as stones is mixed in the sludge. (0010) A third object of the present invention is to provide a sludge dewatering machine that can easily remove dewatered debris adhering to the furnace cloth, does not require cleaning of the furnace cloth, and is easy to maintain. And. (0011)
上記の目的を達成するために、本考案による汚泥脱水機は、垂直な中心軸に、 固定した多数のスリットを有する上広がりの円形カゴ内に、外部からの高圧空気 導入管を有する上下面を塞いだ小形の円形カゴを設け、内カゴ周壁の内外を貫通 する多数の通気口を開け、内カゴと中心軸はスプライン嵌合として内カゴが外カ ゴ内から昇降可能に構成し、外カゴの内周面を炉布で覆い、炉布の一端を外カゴ の上縁に、他端を内カゴの下縁に固定し、内カゴの外周壁をゴム膜で気密に覆っ た。（００１２） 更に、外カゴ内に内カゴを重ねた際にできる炉布とゴム膜の間に汚泥を注入す る汚泥注入管を設け外部動力で中心軸を駆動し外カゴと内カゴを同時に回転させ 得る構造とした。 （００１３） 更に、外カゴの外側を垂直な内筒で覆い、下面に排水口を設け、更に、内筒の 外側に内カゴの昇降に伴って伸縮する垂直な蛇腹を外筒として設けた。 （００１４） In order to achieve the above-mentioned object, the sludge dewatering machine according to the present invention has a vertical center axis and a top-and-bottom surface having a high pressure air introduction pipe from the outside in an upwardly expanding circular basket having a large number of fixed slits. A closed small circular basket is provided, a number of ventilation holes are opened through the inside and outside of the inner basket peripheral wall, and the inner basket and the center shaft are spline-fitted so that the inner basket can move up and down from the outer basket. The inner peripheral surface of the furnace was covered with a furnace cloth, one end of the furnace cloth was fixed to the upper edge of the outer basket, the other end was fixed to the lower edge of the inner basket, and the outer peripheral wall of the inner basket was airtightly covered with a rubber film. (0012) Further, a sludge injection pipe for injecting sludge is provided between the furnace cloth and the rubber film, which is formed when the inner basket is stacked inside the outer basket, and the central shaft is driven by external power to simultaneously drive the outer basket and the inner basket. It has a structure that can be rotated. Further, the outer side of the outer basket is covered with a vertical inner cylinder, a drain port is provided on the lower surface, and a vertical bellows that expands and contracts as the inner basket moves up and down is provided on the outer side of the inner cylinder as the outer cylinder. (0014)
【作用】 本考案の汚泥脱水機の外カゴ４の中に内カゴ５を差し込んで重ね、外カゴ４の 内周面に沿った炉布７と内カゴ５の外周面に沿ったゴム筒８との空間に汚泥注入 管１０より汚泥を注入し、中心軸３を電動モータで駆動回転させて、外カゴ４、 内カゴ５を共に高速回転させて注入した汚泥の水分の一部を遠心分離により除去 する。（遠心分離脱水） （００１５） 続いて、高圧空気を高圧空気管６、送気口、内カゴ内部、通気口を経由してゴ ム筒８の内側に送りゴム筒を膨張させる。ゴム筒８は汚泥を炉布筒７の内側に圧 迫し、この力によって汚泥内の水分は更に炉布筒外に絞りだされる。炉布筒は多 数のスリットを有する外カゴ４で押さえられているので、ゴム筒の圧迫に耐える 。（空気プレス脱水） （００１６） 次にゴム筒８内の高圧空気を抜き、内カゴ５を外カゴ４内から引き上げる。こ の時、炉布筒７の内側に付着した脱水後の汚泥ケーキは炉布筒７の上昇に伴い下 から順次連続してめくられて裏返され、この動作により炉布筒７より剥離して外 カゴ４の外側へ落下する。 （００１７）[Function] The inner basket 5 is inserted into the outer basket 4 of the sludge dewatering machine of the present invention and stacked, and the furnace cloth 7 along the inner peripheral surface of the outer basket 4 and the rubber tube 8 along the outer peripheral surface of the inner basket 5 Sludge is injected into the space of and by the sludge is injected from the pipe 10, the central shaft 3 is driven and rotated by an electric motor, and the outer cage 4 and the inner cage 5 are both rotated at high speed to centrifuge a part of the water content of the sludge. To remove. (Centrifugal Dewatering) (0015) Subsequently, high-pressure air is sent to the inside of the rubber cylinder 8 through the high-pressure air pipe 6, the air supply port, the inner basket, and the ventilation port to expand the rubber cylinder. The rubber cylinder 8 presses the sludge to the inside of the furnace cloth cylinder 7, and the water in the sludge is further squeezed out of the furnace cloth cylinder by this force. Since the furnace cloth cylinder is pressed by the outer basket 4 having many slits, it can withstand the pressure of the rubber cylinder. (Air Press Dehydration) (0016) Next, the high pressure air in the rubber cylinder 8 is evacuated, and the inner basket 5 is pulled up from the outer basket 4. At this time, the dewatered sludge cake adhering to the inside of the furnace cloth cylinder 7 is continuously flipped over from the bottom as the furnace cloth cylinder 7 rises, and is turned over. It falls outside the outer basket 4. (0017)

The outer peripheral surface of the inner basket 5 is covered with a taper tube-shaped rubber cylinder 8, and the upper edge of the rubber cylinder 8 is hermetically sealed to the upper edge 5e of the inner cage 5 and the lower end to the lower edge 5d of the inner cage 5. It is fixed to. The inner basket 5 is held by a spline shaft portion 3a of the central shaft 3 and a spline boss 5f provided at the center of the bottom of the inner basket 5 by spline fitting. As a result, the inner basket 5 cannot rotate with respect to the central shaft 3, It is slidable in the direction. An inner car lifting guide device 13 is provided at the outermost part in order to vertically move the inner car 5 in and out of the outer car 4. (0019) A vertical sludge injection pipe 10 is provided just above the inner basket 5, and sludge is injected from the outside by an anlet pump. The lower end discharge port of the sludge injection pipe 10 is open to a space Z outside the outer diameter D 2 of the upper surface of the inner basket 5 and inside the inner diameter D 1 of the upper surface of the outer basket 4.
