Abstract

<P>PROBLEM TO BE SOLVED: To provide a dust removing screen by which trash that is caught is separated without being lifted above the water surface, and the caught trash is conveyed out of a water passage with the water flow so that a dust removing function can be recovered. <P>SOLUTION: The screen provided with a liftable rake is arranged to face the flow containing the trash. When flow efficiency is deteriorated because of the trash accumulated on the screen, the rake is lowered to rake down the trash on the screen and lead it to a groove in front of a lower part of the screen. When the rake is lowered to the bottom, a tunnel-like space is formed around the trash by the groove and the rake. A gate or a valve is connected to the end of the tunnel-like space, and the other end of the tunnel-like space is opened so that water in the water passage can freely go in and out. Consequently, when the gate or the valve is opened, the water swiftly flows in from the other end because of water pressure, and the trash is pushed away out of the water passage with the water flow. The trash removing function is recoverd when the gate or the valve is closed and the rake is lifted again. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

本発明は、除塵用のスクリーンに係り、特に、夾雑物を水面より上に上げることなく水中でスクリーンから分離し、分離した夾雑物を高速水流(以下ジェット水流と称す)に載せて他の場所に搬送し、スクリーンとしての機能を速やかに回復させることができるようにしたものである。 The present invention relates to a screen for dust removal, and in particular, the contaminants are separated from the screen in the water without raising them above the surface of the water, and the separated contaminants are placed on a high-speed water stream (hereinafter referred to as a jet stream) to other places. The function as a screen can be quickly recovered.

従来の除塵装置は、例えば特開平８−１１３９３０で示されているように、スクリーンで捕獲した夾雑物をレーキで掻揚げて、ベルトコンベア等により別な場所に移動、集積し、産業廃棄物として処理していた。
特開平８−１１３９３０ As shown in, for example, Japanese Patent Laid-Open No. 8-113930, a conventional dust removing device is used to scrape impurities captured by a screen with a rake and move and collect them to another place by a belt conveyor or the like as industrial waste. I was processing.
Japanese Patent Laid-Open No. 8-113930

従来のレーキ掻揚げ式の場合、以下の点が課題となる。 In the case of the conventional rake rake type, the following points are problems.

夾雑物は、水面より上に揚げた時点から産業廃棄物として取り扱われるのが一般的であり、再び水中に戻すことができなくなる。 Contaminants are generally handled as industrial waste when they are raised above the surface of the water, and cannot be returned to the water again.

そのため夾雑物の掻揚げ装置の他に、ベルトコンベア等の掻揚げた夾雑物を移動、集積、管理するための周辺設備が必要となる。 Therefore, in addition to the scraping device for foreign matter, peripheral equipment for moving, accumulating and managing the scraped foreign matter such as a belt conveyor is required.

夾雑物は濡れたまま空中を移動して集積場所でしばらく仮置きされるため、景観が損なわれたり、悪臭が発生しやすい。 Since foreign substances move in the air while wet and are temporarily placed in the accumulation area, the scenery is easily damaged and bad odor is likely to occur.

集積された夾雑物に対しては、管理や産業廃棄物としての処理が必要となり、人的、経済的負担が大きい。 Accumulated contaminants must be managed and treated as industrial waste, resulting in a large human and economic burden.

本発明のトンネル型ジェット水流スクリーンは、水路内にスクリーン本体と、スクリーンが捕獲した夾雑物を掻き下ろす昇降可能なレーキと、レーキの駆動機構を備え、更にレーキが掻き下ろした夾雑物をストックできる細長い空間部をスクリーン本体の下部に備えるとともに、その細長い空間部の一端に開閉装置付きの吐口とそれに接続する水路外部に通じる管路を備えている。The tunnel-type jet water flow screen of the present invention includes a screen body, a rake that can be lifted and lowered to scrape dust captured by the screen, and a drive mechanism for the rake, and can further stock the dust that the rake has swept down. An elongated space portion is provided at the lower portion of the screen body, and at one end of the elongated space portion, a discharge port with an opening / closing device and a conduit connecting to the outside of the water channel connected thereto are provided.

また、本発明のトンネル型ジェット水流スクリーンは、スクリーンが夾雑物を捕獲し、レーキが夾雑物を掻き下ろして前記空間部に夾雑物が溜まると、レーキと細長い空間部の壁で夾雑物の周囲を取り囲み、夾雑物の周りにトンネル状の空間を形成することができる機構を備え、トンネル状の空間を形成した時、開閉装置付きの吐口を備えていない他端は水路内に開放されている。Further, the tunnel type jet water flow screen of the present invention is configured such that when the screen captures impurities, and the rake scrapes the impurities and accumulates the impurities in the space portion, the rake and the slender space wall surround the impurities. The other end that does not have a spout with an opening and closing device is open to the water channel when a tunnel-like space is formed. .

本発明のトンネル型ジェット水流スクリーンは、夾雑物の周囲にトンネル状の空間を形成した時、トンネル状の空間の一端に存在する開閉装置付きの吐口を開放し、水路内に開放されている他端との圧力差によりトンネル内に高速水流を発生させ、水路外部に通じる管路で夾雑物を水路の下流部や夾雑物収集篭等の目的地に搬送することができる。The tunnel-type jet water flow screen according to the present invention is configured such that when a tunnel-like space is formed around a foreign object, a spout with an opening / closing device that is present at one end of the tunnel-like space is opened and opened in the water channel. A high-speed water flow is generated in the tunnel due to the pressure difference with the end, and the contaminants can be transported to a destination such as a downstream portion of the water channel or a contaminant collection tank through a pipe line leading to the outside of the water channel.

夾雑物を水面より上に揚げることなく水中でスクリーンから分離、排除することにより、夾雑物は産業廃棄物としての扱いは受けず、元の水路に戻すことができる。した
がって、産業廃棄物としての管理や処理は不要となる。 By separating and removing the contaminants from the screen in the water without raising them above the water surface, the contaminants are not treated as industrial waste and can be returned to the original waterway. Therefore, management and treatment as industrial waste are not necessary.

また、夾雑物を処理する場合にも、ジェット水流による搬送先に篭を設置すれば夾雑物を集積、回収することができ、ベルトコンベア等の大掛かりな設備が不用となる。 In addition, even when processing foreign matters, if the waste is installed at the transport destination by the jet water flow, the foreign matters can be collected and collected, and a large facility such as a belt conveyor becomes unnecessary.

夾雑物は地下を水とともに移動し、人目につかず悪臭も発生しないことから、周辺の環境に対する影響が少ない。 Since foreign substances move with the water in the basement and are not noticeable and do not generate odors, there is little impact on the surrounding environment.

除塵システム全体が簡素化し、設備費、維持費ともに縮減でき、安全性が高い。 The entire dust removal system is simplified, and both equipment costs and maintenance costs can be reduced, and safety is high.

以下は、本発明の一実施例について、図面を参照し詳述する。 Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

実施例のトンネル型ジェット水流スクリーン１００は、水路内にスクリーン１と、スクリーン１が捕獲した夾雑物２を掻き下ろす降下式レーキ３と、レーキ駆動用モータ４と、スクリーン１の下部にはレーキ３が掻き下ろした夾雑物２をストックできる溝５と、更に溝の端部にはゲート６を備えている。 The tunnel-type jet water flow screen 100 according to the embodiment includes a screen 1 in a water channel, a descent rake 3 that scrapes down impurities 2 captured by the screen 1, a rake drive motor 4, and a rake 3 at the bottom of the screen 1. Are provided with a groove 5 for stocking the impurities 2 scraped down, and a gate 6 at the end of the groove.

除塵時は、レーキ３は水面よりも上に揚げておく。（ステップ1） When dust is removed, the rake 3 is raised above the water surface. (step 1)

スクリーン１から夾雑物２を取り除く場合、レーキ３をスクリーン１に沿って水中に降下させ、スクリーン１の夾雑物２をスクリーン１の下部にある溝５の中に押し下げてスクリーン１から分離すると同時に、レーキ３の一部と溝５とにより夾雑物２の周囲にトンネル状の空間７を形成する。（ステップ2） When removing the contaminant 2 from the screen 1, the rake 3 is lowered into the water along the screen 1, and the contaminant 2 on the screen 1 is pushed down into the groove 5 at the bottom of the screen 1 to separate it from the screen 1. A part of the rake 3 and the groove 5 form a tunnel-like space 7 around the contaminant 2. (Step 2)

レーキ１を降ろしたまま、端部のゲート６を開放すると、水中に開放されている他端から勢い良く水がトンネル状の空間７に流れ込み、ジェット水流となって夾雑物２を水路の外に押し流し、夾雑物２は管路８を通って夾雑物集積用の篭９に搬送される。（ステップ3） When the gate 6 at the end is opened while the rake 1 is lowered, the water flows into the tunnel-like space 7 from the other end that is open to the water, and becomes a jet water flow to bring the contaminants 2 out of the water channel. The impurities 2 are washed away and are conveyed through the pipe line 8 to the impurities collecting basket 9. (Step 3)

そうした後、ゲート６を閉鎖し、最初の位置にレーキ３をセットし、再び除塵を開始する。（ステップ1） After that, the gate 6 is closed, the rake 3 is set at the initial position, and dust removal is started again. (step 1)

以上のプロセスを繰り返すことにより、トンネル型ジェット水流スクリーン１００の除塵機能は維持される。 By repeating the above process, the dust removal function of the tunnel type jet water flow screen 100 is maintained.
