ところで、上記沈砂し渣分離処理装置は、スクリーンを１段階のみ備えたものであったので、沈砂とし渣の分離が今一つ効率的になされず、特に、バキュームダンパーからの投入物がスクリーン上の特定個所に集中的に堆積する傾向となるため、１段階のみのスクリーンではその堆積状態を崩すまでに時間がかかり、振動を付与しても分離の効率化を図るのに一定の限界があった。  By the way, since the above-mentioned sand settling separation apparatus has only one stage of the screen, it is not possible to separate the settling sand and the set-up more efficiently. In particular, the input from the vacuum damper is specified on the screen. Since there is a tendency to accumulate in a concentrated area, it takes a long time to destroy the deposition state with a single-stage screen, and there is a certain limit to improving the efficiency of separation even when vibration is applied.

In these drawings, reference numeral 1 denotes a step-type installation housing, and at a high portion thereof, as shown in FIG. . The vacuum damper 2 is provided with a vacuum tank 5 on a chassis 4 with wheels 3 and can be damped rearward through a fulcrum 6. After the damping, the vacuum damper 2 has been transported by opening the lid 7 at its tail end with a cylinder. It is possible to discharge sand sediment mixed with residue and moisture as shown by arrow B in FIG. Reference numeral 8 denotes a hose connection port portion. In addition to the damping, sand can be discharged through a lead-out hose 9 connected to the connection port portion 8.

沈砂し渣分離処理装置Ａは、架台１１で支持された本体槽１２を備える。本体槽１２は、上部が矩形体に形成されその上端が開放状とされている。本体槽１２の上部内には槽内架台１３が設けられてその上に振動受部１４が複数配備されている。本体槽１２の下部は斜角筒状をなす案内筒部１５として形成されており、その下部には分離砂掻揚装置１６が連通状をなして設けられている。この掻揚装置１６は、分離した砂分を掻き揚げて次の分離砂洗浄装置１７へ導入することにより、砂の洗浄を行うものであり、この洗浄方式には、例えば、本出願人が先に提案した特許第３３９６６８４号、３８１１８８７号、特願２００９−１８８１４４、特願２００９−２３０９８等に開示された技術が適用される。  The sand settling / separation processing apparatus A includes a main body tank 12 supported by a gantry 11. As for the main body tank 12, the upper part is formed in the rectangular body, and the upper end is made into the open shape. A tank mount 13 is provided in the upper part of the main body tank 12, and a plurality of vibration receiving portions 14 are provided thereon. A lower portion of the main body tank 12 is formed as a guide cylinder portion 15 having an oblique cylinder shape, and a separation sand lifting device 16 is provided in a communication shape below the lower portion. This scraping device 16 cleans sand by scooping up the separated sand and introducing it into the next separated sand cleaning device 17. The techniques disclosed in Japanese Patent Nos. 3396684 and 3811887, Japanese Patent Application Nos. 2009-188144, 2009-23098, and the like proposed in Japanese Patent Application No. 2009-23098 are applied.

２０は分離ケーシングで、矩形（正方形など）筒状で上下を開放状としたもので、本体槽１２の上部内に前記振動受部１４にて支持されて設けられている。振動受部１４は、この分離ケーシング２０側あるいは槽内架台１３側に取付けられている。  Reference numeral 20 denotes a separation casing having a rectangular (square or the like) cylindrical shape with an open top and bottom, and is provided in the upper part of the main body tank 12 and supported by the vibration receiving portion 14. The vibration receiving portion 14 is attached to the separation casing 20 side or the tank mount 13 side.

分離ケーシング２０内の下部には主スクリーン２１が水平横断状に設けられ、この主スクリーン２１は、図３にも示すように前後一対に分かれたものでなり、その中間が回転支持手段２２でそれぞれ回転自在に支持されているとともに下ロック２３の抜き差しにより図２の水平な状態と図４の下向きに開かれた状態とが得られるようになっている。主スクリーン２１が、下向きに開かれるのは、主スクリーン２１上に残るし渣分をコンテナ２４に回収するためである。また、この主スクリーン２１の開放および戻しは、分離ケーシング２０上に突設したアイボルトである引っ掛け部２５に掛けられた吊り下げチェーン２６をホイスト（図示省略）にて吊り上げた状態でなされる。尚、主スクリーン２１は、外枠に多数枚の桟板を配列してなるもので、図３にも示すように、ダンパー２が前後進しそれを前後方向Ｃ⇔Ｄと仮定すると各桟板は左右に一定の間隔をおいて並ぶように配列されている。勿論、それに直交する方向に向けられてもよい。分離ケーシング２０の外部には、振動発生機（加振機）２８が設置されている。  A main screen 21 is horizontally provided in the lower part of the separation casing 20, and the main screen 21 is divided into a pair of front and rear as shown in FIG. It is supported rotatably, and the horizontal state of FIG. 2 and the state of opening downward in FIG. 4 can be obtained by inserting and removing the lower lock 23. The main screen 21 is opened downward in order to collect the residue remaining on the main screen 21 in the container 24. Further, the main screen 21 is opened and returned in a state in which a suspension chain 26 hung on a hook portion 25 that is an eyebolt protruding on the separation casing 20 is lifted by a hoist (not shown). The main screen 21 is formed by arranging a large number of crosspieces on the outer frame. As shown in FIG. 3, it is assumed that the damper 2 is moved forward and backward and is assumed to be in the front-rear direction C⇔D. Are arranged side by side at regular intervals. Of course, it may be directed in a direction perpendicular thereto. A vibration generator (vibrator) 28 is installed outside the separation casing 20.

こうした沈砂し渣分離処理装置Ａにおいて、分離ケーシング２０内の主スクリーン２１より上部である前段階には、分配用のスクリーン３０が設けられている。
この分配用スクリーン３０は、分離ケーシング２０の前後の側辺に設けられた回転支持手段３１を介して前後・左右に４分割式に支持され、特に、前側のものは、後方（Ｄ方向）に下がり傾斜状に、また後側のものは、前方（Ｃ方向）に下がり傾斜状をなして全体としてはＶ字谷状に設けられ、それら前後間には抜き差し自在な上ロック３２により受け止め固定されている。In such a sand sedimentation processing apparatus A, a distribution screen 30 is provided in a previous stage above the main screen 21 in the separation casing 20.
The distribution screen 30 is supported in a four-divided manner in the front and rear, left and right via rotation support means 31 provided on the front and rear sides of the separation casing 20, and in particular, the front screen is rearward (D direction). The rear one is inclined downward and the rear one is downwardly inclined (C direction) and is provided with a V-shaped valley as a whole. It is received and fixed by an upper lock 32 that can be freely inserted and removed between them. ing.

図４のように分離ケーシング２０を吊り下げた状態で上ロック３２を抜けば支持が解けて仮想線のように垂直にぶら下がり、その結果、上に残されるし渣がコンテナ２４内に落下回収される。分配用スクリーン３０は、持ち上げられて上ロック３２で受け止めることで次の分離可能状態とされる。主スクリーン２１も同様に持ち上げられて下ロック２３で受け止めることにより分離可能状態になる。これら両スクリーン２１，３０が分離可能状態とされた分離ケーシング２０はホイストで図２のように元の本体槽１２内にマウントされて振動分離態勢とされる。  As shown in FIG. 4, when the separation casing 20 is suspended and the upper lock 32 is removed, the support is released and the support is hung vertically like a phantom line. The The distribution screen 30 is lifted and received by the upper lock 32 to be brought into the next separable state. Similarly, the main screen 21 is lifted and received by the lower lock 23 to be separated. The separation casing 20 in which both the screens 21 and 30 are separable is mounted in the original main body tank 12 by a hoist as shown in FIG.

図３の状態でバキュームダンパー２が到着すると、振動発生機２８が駆動されて加振状態とされ、その状態で矢印Ｂのようにし渣・水混じりの沈砂が投入されると、まず分配用スクリーン３０がそれを受け止めることによって矢印Ｂの直下に落ちるのでなくＸのように沈砂を篩落としながら谷部→後方の分配用スクリーン３０へと分配してゆく。それにより、沈砂は分配を受けながら主スクリーン２１上に落としこまれるようになり、その結果、主スクリーン２１上では、短時間の振動篩を受けるだけでし渣と沈砂とが分離することになる。尚、図２に示すように分配用スクリーン３０上には放水手段３３を設けて投入されたし渣混じりの沈砂をさらに分配するようにしてもよい。  When the vacuum damper 2 arrives in the state of FIG. 3, the vibration generator 28 is driven to be in a vibrating state. In this state, when sand and water-mixed sand is introduced as shown by an arrow B, first, a distribution screen is used. When 30 receives it, it does not fall directly under the arrow B, but distributes it from the trough to the rear distribution screen 30 while sieving the settling sand like X. As a result, the settling sand is dropped onto the main screen 21 while being distributed. As a result, the sediment and the settling sand are separated on the main screen 21 only by receiving a vibrating sieve for a short time. . In addition, as shown in FIG. 2, the water discharge means 33 may be provided on the distribution screen 30 to further distribute the sedimentation sand mixed with the residue.

図５は他の実施形態を示し、この実施形態は、主スクリーン２１および分配用スクリーン３０のそれぞれが軽く回転されるよう回転支持手段２２，３１をスクリーンの略中間個所に設定してある。  FIG. 5 shows another embodiment. In this embodiment, the rotation support means 22 and 31 are set at a substantially intermediate position of the screen so that the main screen 21 and the distribution screen 30 are rotated lightly.

図６の実施形態は、分配用スクリーン３０を前後に長く広いものにして矢印Ｙのように投入物を傾斜方向に流す間に篩にかけるようにするとともに回転操作しやすいように前後間の回転支持手段３１で支持してある。尚、主スクリーン２１は、回転時の分配用スクリーン３０と干渉しないように外開き式にしてある。
分配用スクリーン３０の桟は前後方向（Ｃ⇔Ｄ）に対し直交する方向にその長手方向を向けてあるが、前後方向に平行な方向にその長手方向を向けてもよい。In the embodiment of FIG. 6, the distribution screen 30 is long and wide in the front and rear direction so that the input is passed through the sieve while flowing in the inclined direction as indicated by the arrow Y, and the front and rear rotation is performed so that the rotation operation is easy. It is supported by support means 31. In addition, the main screen 21 is of an outward opening type so as not to interfere with the distribution screen 30 during rotation.
The crosspieces of the distribution screen 30 are oriented in the longitudinal direction in a direction orthogonal to the front-rear direction (C⇔D), but the longitudinal direction may be directed in a direction parallel to the front-rear direction.

図７の実施形態は、分配用スクリーン３０をその中間位置で回転支持手段３１で支持してその軸回りに回転自在でロックも可能なようにするとともに、その傾斜下方端を分離ケーシング２０に対し落下連通路３５を空けて設置し、さらに、主スクリーン２１については、分配用スクリーン３０の回転を阻害しないように落下連通路３５側において回転支持手段２２で支持して傾斜配置し、下ロック２３で開閉自在にしたものである。矢印Ｂの投入物は、分配用スクリーン３０の傾斜に添って篩にかけられながら滑り落下し、そのあと矢印Ｚのように下の主スクリーン２１上に落下してそこでも篩にかけられ分離作用をする。
尚、分配用スクリーン３０は、図６のような方向に桟を設けてもよい。また、主スクリーン２１についても図６の分配用スクリーン３０のような方向に桟を設けてもよい。また、分配用スクリーン３０の傾斜方向端部には枠部のない自由端にしてし渣が下方に落下しやすいようになっているが、枠部を設けてもよい。
主スクリーン２１・分配用スクリーン３０は少なくとも一方をパンチングメタル状のものにしてもよい。In the embodiment of FIG. 7, the distribution screen 30 is supported by the rotation support means 31 at the intermediate position so that the distribution screen 30 can be rotated around its axis and can be locked. The drop communication passage 35 is provided with a space, and the main screen 21 is inclined and supported by the rotation support means 22 on the drop communication passage 35 side so as not to disturb the rotation of the distribution screen 30. It can be opened and closed freely. The input of the arrow B slides and falls while being screened along the inclination of the distribution screen 30, and then falls onto the lower main screen 21 as indicated by the arrow Z and is also screened there for separation. .
The distribution screen 30 may be provided with a cross in the direction as shown in FIG. Further, the main screen 21 may be provided with a crosspiece in a direction like the distribution screen 30 in FIG. In addition, the distribution screen 30 has a free end without a frame portion at the end in the tilt direction so that the residue can easily fall downward, but a frame portion may be provided.
At least one of the main screen 21 and the distribution screen 30 may have a punching metal shape.
