【産業上の利用分野】[Industrial applications]
本考案は小規模下水の処理を効果的に、かつ簡易な装置で行う除塵脱水装置に 関するものである。 The present invention relates to a dust removing and dehydrating apparatus which effectively treats small-scale sewage with a simple apparatus.
【0002】[0002]
【従来の技術】[Prior art]
各家庭より排出される下水は、収集されて下水道を経て下水処理場まで送られ 、この処理場で、まず下水と有機物の固形物とを、いわゆる固液分離を行った後 、汚水は汚水処理槽へ送り、曝気処理を行い、固形物の塵芥は人糞などの未溶解 物等を破砕洗浄する洗浄装置へ送り、その後、洗浄装置より塵芥を掻き揚げ、次 に脱水工程へ送り、脱水して所定の含水率まで低下させて、投棄または焼却処分 としている。 The sewage discharged from each household is collected and sent to the sewage treatment plant through the sewer.At this treatment plant, sewage and organic solids are first subjected to so-called solid-liquid separation, and then sewage is treated as sewage. It is sent to a tank for aeration treatment, and the solid dust is sent to a washing device that crushes and cleans undissolved substances such as human feces, then the dust is scraped from the washing device and then sent to the dehydration process for dehydration. The water content is reduced to the prescribed level and then discarded or incinerated.
【0003】[0003]
【考案が解決しようとする課題】[Problems to be solved by the device]
従来の下水処理は、処理場へ送られてきた下水は固液分離工程を経た後、洗浄 工程・脱水工程を順次経る。そしてこの各工程毎に専用の装置を用いている。従 って大都市等、比較的人口数が多い自治体では大量の下水処理も効率的に行うこ とができるが、その設備は大型なものである。しかし人口数の少ない中小都市の 市町村では、各処理工程毎の単独の設備を互いに連設する、大型大規模処理シス テムを採用することは経済的にも効率的にも困難である。 In conventional sewage treatment, the sewage sent to the treatment plant goes through a solid-liquid separation process, and then a washing process and a dehydration process. A dedicated device is used for each process. Therefore, a municipality with a relatively large population, such as a large city, can efficiently process a large amount of sewage, but its facilities are large. However, in small and medium-sized cities, towns and villages with small populations, it is economically and efficiently difficult to adopt a large-scale large-scale treatment system in which independent facilities for each treatment process are connected to each other.
【0004】 本考案は小規模下水処理設備に適し、かつ大規模処理システムと同等の処理効 果・効率を得ることを目的とする。The present invention is suitable for a small-scale sewage treatment facility and has an object to obtain a treatment effect / efficiency equivalent to that of a large-scale treatment system.

【課題を解決するための手段】[Means for Solving the Problems]
本考案は上記目的を達成するためになしたもので、下水を流入する流入管を接 続した受水槽と、この受水槽下部に横方向に配設され、受水槽より下水を流入す るようになした円筒形スクリーンと、この円筒形スクリーン内にあって円筒形ス クリーンにて固液分離された塵芥を加圧状態で円筒形スクリーン内を移送する回 転スクリューと、塵芥に加圧して脱水する背圧板を備え、かつ前記円筒形スクリ ーンに接続された搬送管とより構成されることを要旨とする。 The present invention was made in order to achieve the above-mentioned object, and a receiving tank connected to an inflow pipe for inflowing sewage and a lateral arrangement below the receiving tank so that the sewage flows from the receiving tank. The cylindrical screen, the rotating screw that transports the dust in the cylindrical screen that has been solid-liquid separated by the cylindrical screen through the cylindrical screen under pressure, and pressurizes the dust. The gist of the present invention is that it comprises a back pressure plate for dehydration and is composed of a carrier pipe connected to the cylindrical screen.

【作 用】[Work]
各家庭から排出された下水は、流入管を経て受水槽内へ導かれる。この受水槽 の下部には回転スクリューを備えた円筒形スクリーンを備えているので、受水槽 より汚物等を含んだ下水を円筒形スクリーン内に供給されると、回転するスクリ ューにて円筒形スクリーン内を移送されるとき、同時に人糞などの未溶解汚物は 圧搾破砕されると共に、受水槽から供給される汚水にて洗浄され、円筒形スクリ ーンにて固液分離が行われる。そしてこの円筒形スクリーン端には、背圧板を備 えた搬送管を接続しているので、円筒形スクリーン内より搬送管内へ、スクリュ ーにて塵芥が押し込められるとき加圧脱水される。これにより一つの設備で下水 の固液分離から未溶解汚物の破砕洗浄、及び加圧脱水まで行われるので、小規模 処理場に適している。 Sewage discharged from each household is introduced into the water receiving tank through the inflow pipe. A cylindrical screen equipped with a rotating screw is provided in the lower part of this water receiving tank, so when sewage containing dirt, etc. is supplied from the water receiving tank into the cylindrical screen, the rotating screen causes the cylindrical screen to rotate. At the same time, undissolved sewage such as human feces is crushed by squeezing when it is transported inside, washed with sewage supplied from the water receiving tank, and solid-liquid separation is performed with a cylindrical screen. Since a conveying pipe equipped with a back pressure plate is connected to the end of the cylindrical screen, when the dust is pushed into the conveying pipe from the cylindrical screen by a screw, it is pressurized and dehydrated. This makes it possible to perform solid-liquid separation of sewage, crush and wash undissolved sewage, and pressure dehydration in one facility, making it suitable for small-scale treatment plants.

【実施例】【Example】
以下本考案除塵脱水装置を図示の実施例にもとづいて説明する。 図に於いて1は各家庭等より排出される下水を集水して、下水道等を経て処理 場へ送るための流入管で、この流入管1の終端を所要の容量を有する受水槽2に 接続される。この受水槽2の下部はロート状となし、受水槽底部より集水して排 出されるように排水管部21を設ける。 The dust removing and dehydrating apparatus of the present invention will be described below with reference to the illustrated embodiment. In the figure, 1 is an inflow pipe for collecting sewage discharged from each household and sending it to the treatment plant through sewers, etc. The end of this inflow pipe 1 is placed in a receiving tank 2 having a required capacity. Connected. The lower portion of the water receiving tank 2 is formed in a funnel shape, and a drain pipe portion 21 is provided so that water is collected and discharged from the bottom of the water receiving tank.
【0008】 受水槽2の下部には、水平もしくは所要の緩やかな傾斜角をして、横方向にし かも塵芥の洗浄と脱水を行うに適した所要の長さと径を備えた円筒形スクリーン 3を配設する。この円筒形スクリーン3は下水中の固形分、すなわち除去すべき 塵芥の大きさに合わせて、その目幅が適当に定められ、この一端部上面に開口部 を設け、受水槽側の排水管部21と接続され、受水槽からの固形分を含んだ汚水 が円筒形スクリーン内へ供給できるようになす。At the lower part of the water receiving tank 2, there is provided a cylindrical screen 3 having a required length and a diameter which is suitable for cleaning and dewatering dust in a horizontal direction or at a required gentle inclination angle. Arrange. The cylindrical screen 3 has an appropriate mesh width according to the solid content in the sewage, that is, the size of dust to be removed. An opening is provided on the upper surface of one end of the cylindrical screen 3, and the drain pipe section on the water receiving tank side is provided. It is connected to 21 so that the sewage containing solids from the water receiving tank can be supplied into the cylindrical screen.
【0009】 円筒形スクリーン3の基端側には、スクリュー駆動用の駆動装置4を、他端側 には脱水後塵芥を搬送する搬送管5を設けると共に、円筒形スクリーン3内にス クリュー6を嵌挿する。このスクリュー6は円筒形スクリーン3の内径より少し 小さい外径を備え、長さはスクリーン長より少し長くし、スクリュー先端は円筒 形スクリーンの先端より突出し、搬送管内へ挿入されるようになすと共に、駆動 装置4にて予め定めた回転数にて駆動される。A driving device 4 for driving a screw is provided on the proximal end side of the cylindrical screen 3, and a conveying pipe 5 for conveying debris after dehydration is provided on the other end side, and a screw 6 is provided in the cylindrical screen 3. Insert. The screw 6 has an outer diameter slightly smaller than the inner diameter of the cylindrical screen 3, its length is slightly longer than the screen length, and the screw tip projects from the tip of the cylindrical screen so that it can be inserted into the conveying pipe. It is driven by the drive device 4 at a predetermined rotation speed.
【0010】 スクリュー6のピッチは全長にわたり等しいピッチにしても良いが、時にはそ のピッチをスクリューの始端側と終端側、あるいは中央部と変えるように、洗浄 ・破砕、及び加圧脱水をより効果的に行うようになすこともできる。The pitch of the screw 6 may be the same over the entire length, but sometimes cleaning / crushing and pressure dehydration are more effective so that the pitch is changed to the starting end side and the ending side of the screw, or the central part. You can also do it as you want.
【0011】 搬送管5にはその一部、望ましくは基端側近傍に背圧板7を揺動自在に設け、 この背圧板を搬送管内に所要圧にて挿入させ、スクリュー6にて搬送管内に押し 込められる塵芥に加圧し、脱水するもので、この背圧板7の加圧は図1、図2に 示すように搬送管5の両側部に加圧用ばね装置8,8を設け、このばね圧を背圧 板7に作用するようになす。またはこのばね装置に代わって油圧シリンダを用い ることも、あるいは加圧力調整式とすることも可能である。A back pressure plate 7 is swingably provided in a part of the transport pipe 5, preferably near the base end side, and the back pressure plate 7 is inserted into the transport pipe at a required pressure and is screwed into the transport pipe. The back pressure plate 7 is pressurized by pressing the dust that is pushed in and dehydrating it. As shown in FIGS. 1 and 2, pressing spring devices 8 and 8 are provided on both sides of the conveying pipe 5, and this spring pressure is applied. To act on the back pressure plate 7. Alternatively, a hydraulic cylinder may be used in place of this spring device, or a pressure adjusting type may be used.
【0012】 受水槽2内に供給される水量が、予め定めた一定量以下の場合、受水槽より連 続して円筒形スクリーンへ汚水を供給しても汚水による洗浄水の不足により円筒 形スクリーン内にて捕捉された塵芥の洗浄が効果的に行えない場合もある。この ような場合、供給水量の不足を補うため、受水槽から汚水の供給を断続的に行う 。これはスクリュー6に、しかも排水管部21の下方位置に円弧形のゲート板9 を、少なくとも排水管部端面を閉鎖できる大きさにして一体に設け、スクリュー と共に回動させるようになす。When the amount of water supplied to the water receiving tank 2 is equal to or less than a predetermined fixed amount, even if the waste water is continuously supplied from the water receiving tank to the cylindrical screen, the shortage of washing water due to the waste water causes the cylindrical screen. In some cases, the dust trapped inside may not be effectively cleaned. In such a case, in order to make up for the lack of water supply, sewage is intermittently supplied from the receiving tank. This is so constructed that an arcuate gate plate 9 is integrally provided on the screw 6 and below the drain pipe portion 21 in such a size that at least the end face of the drain pipe portion can be closed, and is rotated together with the screw.
【0013】 これによりスクリュー6の回動にてゲート板6が排出管部直下にある時、外管 部が閉塞されて汚水の円筒形スクリーンへの供給が停止され、受水槽内にて一時 貯留される。そしてゲート板9が排水管部を過ぎると、受水槽より汚水が円筒形 スクリーン内に供給され、洗浄が行われるものである。As a result, when the gate plate 6 is directly below the discharge pipe portion due to the rotation of the screw 6, the outer pipe portion is closed and the supply of the dirty water to the cylindrical screen is stopped, and the water is temporarily stored in the water tank. To be done. Then, when the gate plate 9 passes the drain pipe portion, dirty water is supplied from the water receiving tank into the cylindrical screen for cleaning.
【0014】 なお、この洗浄用としての汚水量を一定量以上となるようにするためには、受 水槽2に水位計を設け、この水位計の計測データに基づき、排水管部よりの汚水 の円筒形スクリーンへの供給を制御することもできる。これは排水管部に開閉操 作可能なゲート板を設けるか、あるいはスクリューにゲート板を設けた実施例で は、このスクリューの回転制御をすることによって行うものである。In order to keep the amount of sewage for cleaning above a certain amount, a water level gauge is provided in the water receiving tank 2, and the sewage from the drain pipe section is measured based on the measurement data of this water level gauge. It is also possible to control the feed to the cylindrical screen. This is done by providing a gate plate that can be opened and closed in the drain pipe section, or by controlling the rotation of this screw in the embodiment in which the gate plate is provided in the screw.
【0015】 さらにスクリュー6の先端は、円筒形スクリーン端より少し搬送管内側へ突出 するようにするが、このスクリュー先端を図5に示すように鋸歯状とすることも できる。このスクリュー端が円筒形スクリーン端により、少し突出させることに よって円筒形スクリューにかかった塵芥を前方へ掻き取り、最終的に剪断できる ものとなる。Further, the tip of the screw 6 is made to project slightly inward from the end of the cylindrical screen, but the tip of the screw may be serrated as shown in FIG. The end of this screw is made to protrude slightly by the end of the cylindrical screen, so that the dust on the cylindrical screw can be scraped forward and finally sheared.
