(57) [Abstract] [Purpose] We propose a dewatering device for sewer residue in sewers, which can easily wash and separate the contaminants adhering to the residue. [Structure] In a sewer screen dehydrator, a feed device provided in a screen cylinder is a screw shaft, and a cleaning pipe is opened so as to face a terminal end of a screw wound around the screw shaft. Since the residue sent by the screw is crushed, the contaminants adhering to it can be washed off completely. Also, since the residue sent in has not yet solidified, the cleaning water pressure may be low,
Both the drive power of the device and the amount of washing water are small.

この考案は、下水等のし渣脱水機におけるし渣の洗浄装置に関する。 The present invention relates to an apparatus for cleaning residue on a residue dehydrator such as sewage.
【0002】[0002]
従来のし渣の脱水機としては、特開平4−66297の図面に示すようなもの がある。この発明では、スクリーン上のし渣をプランジャーで搬送するようにし ており、し渣に付着している夾雑物やスクリーンに付着する夾雑物の洗浄につい ては触れていないが、洗浄が必要な場合には、スクリーンの末端で高圧水等で洗 浄するようにしている。 A conventional screen residue dehydrator is shown in the drawing of Japanese Patent Laid-Open No. 4-66297. In this invention, the residue on the screen is conveyed by a plunger, and cleaning of contaminants adhering to the residue and contaminants adhering to the screen is not mentioned, but cleaning is required. In some cases, the end of the screen is washed with high pressure water.
【0003】[0003]
然しながら、生活排水やし尿等から成る下水には、毛髪や紙片等の繊維状のも のの他に糞便等各種の固形夾雑物を含んでおり、これらは、スクリーン部分で分 離できず、し渣に付着したままスクリーンの末端部に送られる。このため、スク リーン末端には、固形夾雑物のために固化したし渣が堆積し、排出不能となるこ とがしばしば発生する。このような場合、従来においては固化したし渣に対して 高圧洗浄水を噴射してし渣を洗浄しているが固化しているために洗浄が極めて困 難である。 However, sewage consisting of domestic wastewater and human waste contains various solid impurities such as feces in addition to fibrous substances such as hair and paper pieces, which cannot be separated on the screen part. It is sent to the end of the screen while still attached to the residue. For this reason, solid residue is often accumulated at the end of the screen due to solid contaminants, which often makes discharge impossible. In such a case, conventionally, high-pressure washing water is sprayed on the solidified residue to wash the residue, but it is extremely difficult to clean because it is solidified.

この考案は、上述のような課題を解決したものであって、送り装置としてスク リュー軸を用いてし渣を破砕するとともに、破砕したし渣を洗浄するようにした ものであり、その要旨とするところは、スクリーン筒内にスクリュー軸を支架し てスクリーンの一端から供給した原液を他端に向かって搬送してろ過脱水するよ うにしたし渣の脱水機において、上記スクリーンの終端部分に、上記スクリュー 軸2に巻き回した送り用の螺旋翼の末端部に臨ませて洗浄水管を開口させたもの である。 The present invention solves the above-mentioned problems, and uses a screw shaft as a feeding device to crush crushed residue and to wash the crushed residue. In the place where the screw shaft is supported in the screen cylinder and the undiluted solution supplied from one end of the screen is conveyed toward the other end to be filtered and dehydrated, in the screen residue dehydrator, at the end part of the screen, The washing water pipe is opened so as to face the end portion of the feed spiral blade wound around the screw shaft 2.

この考案に係る装置は、上述のように構成してあり、送り装置としてスクリュ ー軸を用いているので、原液中の脱水されたし渣は、スクリュー軸で送られる間 にその螺旋翼で破砕される。そして、この破砕されたし渣に対して洗浄水が放出 されるので、これに付着した夾雑物を完全に洗い落すことができる。すなわち、 この考案では、脱水直後固化していないし渣が洗浄されるので、固形物を容易に 分離することができ、洗浄水も少なくて済み、その圧力も低圧で足りるものであ る。尚、夾雑物を含む洗浄水はスクリーンを経て排出されるものである。以下、 図面に基づいて、この考案を具体的に説明する。 Since the device according to the present invention is configured as described above and uses the screw shaft as the feeding device, the dehydrated residue in the stock solution is crushed by the spiral blade while being fed by the screw shaft. To be done. Then, since the washing water is discharged to the crushed residue, the contaminants attached to it can be washed off completely. In other words, in this invention, since the solidified residue and the residue are washed immediately after dehydration, the solid matter can be easily separated, less washing water is required, and the pressure thereof is low. The washing water containing impurities is discharged through the screen. The present invention will be specifically described below with reference to the drawings.

図1は、し渣脱水機の要部を示し、図中、符号1はスクリーン筒、2はスクリ ーン筒1内に支架したスクリュー軸、2aはスクリュー軸2に巻き回した送り用 の螺旋翼、3は汚水の流入口、4はし渣の圧搾管、5は脱水部を内装するケーシ ングで底部に処理水の受皿5aが形成してある。次に、符号6は洗浄水管であり 、スクリュー軸2および螺旋翼2aの末端に臨ませて開口させてある。図例では 図2に示すように2個の放出口6aが設けてある。尚、符号Sは、圧搾管4に送 られてきたし渣を示し、このし渣は、圧搾管4に接続された排出管7内に順次送 られて機外に取り出されるものである。符号9は、送り軸2の駆動スプロケット 、10はマンホールのカバーを示すものである。 FIG. 1 shows a main part of a residue dehydrator. In the figure, reference numeral 1 is a screen cylinder, 2 is a screw shaft supported in the screen cylinder 1, and 2a is a feed spiral wound around the screw shaft 2. The blades 3 are inlets for sewage, 4 squeeze pipes for residue, and 5 are casings for incorporating a dehydration section, and a treated water tray 5a is formed at the bottom. Next, reference numeral 6 is a washing water pipe, which is opened so as to face the ends of the screw shaft 2 and the spiral blade 2a. In the illustrated example, as shown in FIG. 2, two discharge ports 6a are provided. In addition, the symbol S indicates the residue that has been sent to the compression tube 4, and this residue is sequentially sent into the discharge pipe 7 connected to the compression tube 4 and taken out of the machine. Reference numeral 9 is a drive sprocket for the feed shaft 2, and 10 is a manhole cover.
【0007】 この考案に係るし渣の洗浄装置は上述のように構成してあり、流入口3から供 給された汚水は、スクリーン筒1内を螺旋翼2aによって搬送されつつ、スクリ ーン1によってろ過される。そして、スクリュー軸2の末端部には、汚水中のし 渣Sのみが送られてきて洗浄管6からの放水によって洗浄される。すなわち、汚 水から分離されたし渣Sには、スクリーン1で分離できない糞塊等の固形物が付 着しているが、これらを完全に洗い流すことができるものである。その洗浄水は 、スクリーン筒1を通して受皿5aへと分離され、洗浄されたし渣Sは、続いて 回転している螺旋翼2aによって圧搾管4へと圧送され、さらに、この洗浄圧搾 されたし渣Sは排出管7を経て機外に取り出される。The residue cleaning apparatus according to the present invention is configured as described above, and the sewage supplied from the inflow port 3 is conveyed inside the screen cylinder 1 by the spiral blades 2a while the screen 1 is being conveyed. Filtered by. Then, only the residue S in the dirty water is sent to the end portion of the screw shaft 2 and is washed by discharging water from the washing pipe 6. That is, the solid residue such as stool mass that cannot be separated by the screen 1 is attached to the residue S separated from the waste water, but these can be completely washed away. The washing water is separated into the saucer 5a through the screen cylinder 1, and the washed residue S is then pumped to the squeeze pipe 4 by the rotating spiral blade 2a and further squeezed and squeezed. The residue S is taken out of the machine through the discharge pipe 7.
【0008】 以上のし渣の脱水洗浄操作において、この考案では、スクリーン筒1内に設け る送り装置が螺旋翼2aを有するスクリュー軸2で構成してあるので、搬送中に おいて水分が分離されたし渣Sを破砕することができ、この破砕されたし渣Sに 洗浄水が放出されるので、付着した固形物を完全に洗い流すことができる。また 、この洗浄水の放出は、送られてきた直後の固形物が固化していないし渣に行わ れるので、洗い易く高圧の洗浄水を必要としない。In the dewatering and washing operation of the residue as described above, in this invention, since the feeding device provided in the screen cylinder 1 is constituted by the screw shaft 2 having the spiral blade 2a, the water is separated during the transportation. The smashed residue S can be crushed, and the washing water is discharged to the crushed residue S, so that the adhered solid matter can be completely washed away. In addition, since the washing water is released immediately after being sent to the residue which is not solidified and remains, it is easy to wash and does not require high-pressure washing water.
