【産業上の利用分野】[Industrial applications]
この考案は、下水の終末処理場等に設けられるし渣の脱水機におけるし渣の洗 浄装置の改良に関する。 The present invention relates to an improvement of a screen residue cleaning device in a screen residue dehydrator provided in a sewage terminal treatment plant or the like.
【0002】[0002]
【従来の技術】[Prior Art]
従来、下水等の終末処理場で下水から分離されたし渣を洗浄する装置は公知で ある。実公昭56−10475号考案はその一例であり、この考案では、下水か ら分離したし渣を潰砕した上で洗浄し、その後水切りを行うようにしている。 2. Description of the Related Art Conventionally, a device for washing residue that has been separated from sewage at a terminal treatment plant such as sewage is known. The Japanese Utility Model Publication No. 56-10475 is one such example. In this invention, the residue separated from the sewage is crushed, washed, and then drained.

【考案が解決しようとする課題】[Problems to be solved by the device]
すなわち、上述の従来技術では、下水から分離したし渣を潰砕した上で洗浄し 、さらに、二段階に水切りを行うようにしている。従って、し渣の分離装置が必 要な上に、潰砕装置、水洗装置および水切装置を必要とする。そして、下水から 分離して固化したし渣は洗浄しにくく、その処理操作が煩雑なのみならず、上述 のような諸装置が必要であり処理費も高価となる難点がある。 That is, in the above-mentioned conventional technique, the residue separated from the sewage is crushed, washed, and then drained in two steps. Therefore, in addition to a screen residue separating device, a crushing device, a water washing device and a draining device are required. The solid residue separated and solidified from the sewage is difficult to wash, the processing operation is complicated, and the above-mentioned various devices are required and the processing cost is high.
【0004】[0004]
【課題を解決するための手段】[Means for Solving the Problems]
この考案は、上述のような従来の難点を解消したものであって、その要旨とす るところは、その内部に送り軸を設けたスクリーンの始端上方に下水の供給槽を 設け、その供給槽の下部の排出口をスクリーンの始端部に連通させるとともに、 その排出口の連通部後段におけるスクリーンには、洗浄装置を設けたものである 。 This invention eliminates the above-mentioned conventional difficulties, and the gist of the invention is to provide a sewage supply tank above the starting end of a screen having a feed shaft inside, and to provide the supply tank. The discharge port at the bottom of the screen is connected to the start end of the screen, and a cleaning device is provided on the screen at the latter stage of the communication part of the discharge port.

【作用】[Action]
この考案に係る装置は上述のように構成されており、し渣を含む下水が供給槽 から流下してスクリーンによって水分が分離され、送り軸の螺旋翼によってスク リーンの他端に向かって搬送される。そして、この搬送されるし渣は、洗浄され たのち機外に取り出される。すなわち、この考案では、下水を直接スクリーンに 供給することによって、微量段階でし渣を捕捉分離し、然も、下水は、供給槽の ヘッドを有するのでし渣に付着する粉塊を破砕して効率よく分離することができ るものであり、さらに、このようにして分離されたし渣は、小粉塊が付着してい ても洗浄装置によって洗浄されるもので完全な洗浄が可能である。以下、図面に 基づいてこの考案を具体的に説明する。 The device according to the present invention is configured as described above, and the sewage containing residue flows down from the supply tank, the water is separated by the screen, and is conveyed toward the other end of the screen by the spiral blade of the feed shaft. It Then, the transferred residue is washed and then taken out of the machine. In other words, in this device, the sewage is directly supplied to the screen to capture and separate the residue in a trace amount. It can be efficiently separated, and the residue thus separated is cleaned by a cleaning device even if small lumps of powder adhere to it, and complete cleaning is possible. Hereinafter, the invention will be specifically described with reference to the drawings.

【実施例】【Example】
図において、符号1はスクリーンで始端部は上方が開放した樋状に、後端部は ドラム状に構成してある。2はスクリーン内に横架した送り軸、2aは送り用の 螺旋翼、3はスクリーンの後端部の中位部に設けた洗浄器、4はスクリーン1に 接続したし渣の排出筒で上方に立ち上がらせてその先端開口にはダンパー5が設 けてある。このダンパー5は、スプリング6によって排出筒4の開口を常態では 閉止するように付勢されている。 In the figure, reference numeral 1 is a screen, which has a gutter shape with its upper end opened and a drum shape with its rear end. Reference numeral 2 is a feed shaft horizontally laid inside the screen, 2a is a spiral blade for feeding, 3 is a cleaning device provided at a middle portion of the rear end of the screen, 4 is a screen for discharging the residue connected to the screen 1 There is a damper 5 at the tip opening. The damper 5 is biased by a spring 6 so as to normally close the opening of the discharge tube 4.
【0007】 次に、図において、符号7は下水の供給槽であって、流入管7aより下水が直 接流入するようにしてあり、この供給槽7の底部は上述のスクリーン1の始端部 に連通させてある。符号8は処理水槽、8aは処理水の排出管である。なお、図 中の矢印は、下水、処理水、洗浄水およびし渣の流れを示し、符号イは下水の流 れ、ロは処理水の流れ、ハはし渣の流れ、ニは洗浄水を示すものである。Next, in the figure, reference numeral 7 is a sewage supply tank, which is designed so that the sewage directly flows in through an inflow pipe 7 a, and the bottom of the supply tank 7 is located at the starting end of the screen 1. It is in communication. Reference numeral 8 is a treated water tank, and 8a is a treated water discharge pipe. The arrows in the figure indicate the flow of sewage, treated water, wash water and residue, where symbol a is the flow of sewage, b is the flow of treated water, c is the flow of residue and d is the wash water. It is shown.
【0008】 この考案に係る装置は上述のように構成してあり、供給槽7からスクリーン1 内に落下する下水はスクリーン1により含有するし渣が捕捉され、分離した処理 水は、処理水槽8を経て排出管8aから機外に取り出される。一方、分離された し渣は、送り軸2の螺旋翼2aによってスクリーン1の他端に向かって搬送され 、スクリーン1の後部の中位部で洗浄されたのち、水分を切られつつ排出筒4へ と送られる。そして、排出筒4内では、ダンパー5が閉止していることから圧密 状となって圧搾されてさらに水を切られたのち、ダンパー5を押し開いて機外に 排出される。The apparatus according to the present invention is configured as described above, the sewage falling from the supply tank 7 into the screen 1 is captured by the screen 1, and the separated treated water is separated into the treated water tank 8 Then, it is taken out of the machine through the discharge pipe 8a. On the other hand, the separated residue is conveyed toward the other end of the screen 1 by the spiral blade 2a of the feed shaft 2, washed in the middle part of the rear part of the screen 1, and then drained while draining water. Sent to. Then, since the damper 5 is closed inside the discharge tube 4, the damper 5 is compressed and squeezed to further drain water, and then the damper 5 is pushed open and discharged to the outside of the machine.
【0009】 以上のような、処理操作において、この考案では、下水からし渣を分離するこ となく、いきなり下水をスクリーンにかけて分離するので、特別な分離装置を必 要とせず、装置が簡単となり、これに伴って処理操作も簡単に済み、また、し渣 が稀薄な下水を直接スクリーンにかけるので、分離がし易い上多量の下水を洗浄 水として利用することができ、さらに、このようにして洗浄されたし渣を洗浄す るので、完全に洗浄されたし渣を得ることができる。In the treatment operation as described above, according to the present invention, the sewer is separated from the sewage without being separated from the sewage, and the sewage is suddenly separated by a screen. In connection with this, the treatment operation is simple, and since the sewage with a thin residue is directly applied to the screen, it is easy to separate and a large amount of sewage can be used as washing water. Since the washed residue is washed with water, a completely washed residue can be obtained.

【考案の効果】[Effect of the device]
このように、この考案は、下水を直接スクリーンにかけて、し渣の分離が容易 な段階で多量の下水を洗浄に利用するとともに、このようにして洗浄したし渣を さらに完全に洗浄するようにしたものであって、従来のこの種し渣の洗浄装置に 比較して装置、およびその処理操作が簡単であり乍らその洗浄効果が格段にすぐ れるものである。 As described above, the present invention is designed so that sewage is directly applied to the screen, a large amount of sewage is used for washing at a stage where separation of the residue is easy, and the residue thus washed is further thoroughly cleaned. However, compared to the conventional cleaning device for this kind of residue, the device and its processing operation are simple, and the cleaning effect is remarkably excellent.
