Description

本発明は、槽の底に堆積した堆積物を掻き寄せることが可能であると共に、槽内の水面に浮上する浮上物を掻き寄せることも可能な堆積物及び浮上物の掻寄装置に関する。   The present invention relates to a deposit and a levitated scraping device that can scrape deposits accumulated on the bottom of a tank and can also levitate levitated objects floating on the water surface in the tank.

従来、例えば沈殿地等の槽の底に堆積する堆積物を効率的に掻き寄せる堆積物の掻寄装置として、揺動可能な掻寄羽根を備える掻寄架台を槽内で往復動させ、掻寄架台の往動時には、掻寄羽根を垂下させた第一の状態で、槽の底の堆積物を往動方向に掻き寄せて、往動方向の端にあるピットへ送り込み、掻寄架台の復動時には、槽の底の堆積物を掻寄羽根により戻さないように、掻寄羽根を第一の状態から揺動させて槽の底から離間させる堆積物の掻寄装置が知られている(例えば、特許文献1参照)。
特開2003−181209号公報
Conventionally, for example, as a deposit scraping device that efficiently scrapes deposits deposited on the bottom of a tank such as a sedimentation site, a scraping stand having a swinging scraping blade is reciprocated in the tank, During the movement of the platform, in the first state where the scraping blades are suspended, the sediment at the bottom of the tank is scraped in the forward direction and sent to the pit at the end of the forward direction. In order to prevent the deposit on the bottom of the tank from being returned by the scraping blade at the time of return, there is known a scraping device that swings the scraping blade from the first state and separates it from the bottom of the tank. (For example, refer to Patent Document 1).
JP 2003-181209 A

ここで、沈殿地等にあっては、槽内の水面にスカム等の浮上物が浮上するため、上記堆積物の掻寄装置に、浮上物の掻き寄せ機能を装備することが求められている。   Here, in the sedimentation place and the like, floating objects such as scum float on the surface of the water in the tank. Therefore, it is required to equip the deposit scraping device with a function of scraping floating objects. .

本発明は、このような課題を解決するために成されたものであり、低コスト化を図りつつ、効率的且つ確実に堆積物及び浮上物を掻き寄せることが可能な堆積物及び浮上物の掻寄装置提供することを目的とする。   The present invention has been made in order to solve such a problem, and it is possible to reduce deposits and levitated materials that can efficiently and reliably scrape debris and levitated materials while reducing costs. An object is to provide a scraping device.

本発明による堆積物及び浮上物の掻寄装置は、槽内で往復動する掻寄架台と、この掻寄架台の下部側に揺動可能に支持され、掻寄架台の往動時には、下方に垂下した垂下状態で槽の底の堆積物を往動方向に掻き寄せ、掻寄架台の復動時には、垂下状態から揺動され底から離間した離間状態とされる堆積物用掻寄羽根と、掻寄架台の上部側に位置し、堆積物用掻寄羽根の揺動に機械的に連動して槽の水面から出没する浮上物用掻寄羽根と、を備えることを特徴としている。   The scraping device for deposits and levitated objects according to the present invention is supported by a scraping base that reciprocates in the tank and swingable on the lower side of the scraping base. In the suspended state, the deposit on the bottom of the tank is scraped in the forward movement direction, and when the scraping table is moved back, the scraping blade for the deposit that is swung from the suspended state and separated from the bottom, It is located on the upper side of the scraping stand, and is characterized by comprising a floating blade for floating material that appears and disappears from the surface of the tank mechanically interlocking with the rocking of the depositing blade.

このような堆積物及び浮上物の掻寄装置によれば、掻寄架台の往動時には、堆積物用掻寄羽根が下方に垂下した垂下状態で槽の底の堆積物を掻き寄せ、掻寄架台の復動時には、堆積物用掻寄羽根が垂下状態から揺動し槽の底から離間した離間状態とされる一方で、掻寄架台の上部側に位置する浮上物用掻寄羽根は、堆積物用掻寄羽根の揺動に機械的に連動して槽の水面から出没し、槽の水面上に現れている際には、水面の浮上物を掻き寄せ、槽の水面下に没している際には、槽の水面から離間した状態とされる。このため、堆積物用掻寄羽根による堆積物の掻き戻し、浮上物用掻寄羽根による浮上物の掻き戻しが無く、堆積物及び浮上物は円滑に掻き寄せられる。また、浮上物用掻寄羽根のための動力は別途必要無い。   According to such a scraping device for deposits and levitated objects, when the scraping table moves forward, the deposits on the bottom of the tank are scraped and scraped with the scraping blades for deposits hanging downward. At the time of return of the gantry, the scraping blade for deposit is swung from the suspended state and separated from the bottom of the tank, while the swaying blade for floating material located on the upper side of the cradle is When it appears on the surface of the tank mechanically interlocking with the rocking blades for deposits, and appears on the surface of the tank, the surface floats up and sinks below the surface of the tank. When it is, it is in a state of being separated from the water surface of the tank. For this reason, there is no scraping back of the deposit by the scraping blade for deposit, and no scraping back of the floating material by the scraping blade for floating material, and the deposit and the floating material are scraped smoothly. In addition, there is no need for power for the scraping blades for floating objects.

ここで、浮上物用掻寄羽根は、掻寄架台の上部側に揺動可能に支持され、揺動に従って水面から出没する構成であると、浮上物用掻寄羽根が水面に対して略垂直に出没する構成に比して、水面下に没した状態での移動の際(非掻き寄せ時)の抵抗が少なくされると共に確実に掻き戻しが無くされる。   Here, the levitated scraping blade is supported on the upper side of the cradle base so as to be swingable, and the levitated scraping blade is substantially perpendicular to the water surface when it is configured to protrude from the water surface according to the swing. Compared with the structure that appears and disappears, the resistance when moving in the state of being submerged under the surface of the water (at the time of non-scraping) is reduced and the scraping is surely eliminated.

また、例えば汚泥等を含む排水等が槽内に供給されると、汚泥等の堆積物はその多くが上流側に残り、浮上物は槽の下流側へと向かう。このため、堆積物の排出位置が、槽の上流側に設定され、浮上物の排出位置が、槽の下流側に設定され、浮上物用掻寄羽根は、堆積物用掻寄羽根が垂下状態とされ槽の上流側へ向かう掻寄架台の往動時に水没し、堆積物用掻寄羽根が離間状態とされ槽の下流側へ向かう掻寄架台の復動時に水面上に現れる構成であると、堆積物は堆積物の排出位置へ、浮上物は浮上物の排出位置へ一層効率的に掻き寄せられる。   For example, when drainage containing sludge or the like is supplied into the tank, most of the sediment such as sludge remains on the upstream side, and the levitated material moves toward the downstream side of the tank. Therefore, the sediment discharge position is set on the upstream side of the tank, the floating material discharge position is set on the downstream side of the tank, and the floating scraping blade is in a suspended state. And the submerged submergence head toward the upstream side of the tank is submerged, and the scraping blades for deposits are separated and appear on the water surface when the rear counter unit moves downstream of the tank. The deposit is more efficiently scraped to the deposit discharge position, and the levitated object is more efficiently scraped to the levitated discharge position.

また、堆積物用掻寄羽根及びこれに機械的に連動する浮上物用掻寄羽根の組合せを、掻寄架台の往復動方向に複数組備えているのが好ましい。   Further, it is preferable that a plurality of combinations of the scraping blade for deposits and the flying blade for mechanically interlocking with the depositing blade are provided in the reciprocating direction of the scraping base.

このような構成を採用した場合、並列される堆積物用掻寄羽根の各々が揺動すると共に、この堆積物用掻寄羽根の各々の揺動に機械的に連動して、並列される浮上物用掻寄羽根の各々が水面から出没し、堆積物、浮上物は、並列される掻寄羽根により分担されて次の掻寄羽根へと順次掻き寄せられていく。このため、掻寄架台の往復動の距離が短くされる。   When such a configuration is adopted, each of the deposited scraping blades oscillated in parallel and mechanically interlocked with each of the deposited scraping blades, Each of the scraping blades for objects appears and disappears from the surface of the water, and the deposits and floating objects are shared by the parallel scraping blades and sequentially scraped to the next scraping blade. For this reason, the distance of the reciprocating motion of the scraper is shortened.

また、堆積物用掻寄羽根及び浮上物用掻寄羽根は各々、掻寄架台の往復動方向に複数並設され、堆積物用掻寄羽根及びこれに機械的に連動する浮上物用掻寄羽根の組合せを少なくとも一組備え、浮上物用掻寄羽根の動作を互いに連動させる連結手段を備えているのが好ましい。   In addition, a plurality of the scraping blades for deposits and the scraping blades for floating objects are arranged in parallel in the reciprocating direction of the scraping platform, and the scraping blades for deposits and the scraping blades for floating objects that are mechanically linked to the scraping blades. It is preferable that at least one combination of blades is provided, and a connecting means for interlocking the operations of the flying object scraping blades is provided.

このような構成を採用した場合、並列される堆積物用掻寄羽根の各々が揺動すると共に、少なくとも一つの堆積物用掻寄羽根の揺動に機械的に連動して、この堆積物用掻寄羽根と組を成す浮上物用掻寄羽根が水面から出没し、連結手段により、当該浮上物用掻寄羽根の出没に連動して、並列される他の浮上物用掻寄羽根が水面から出没し、堆積物、浮上物は、並列される掻寄羽根により分担されて次の掻寄羽根へと順次掻き寄せられていく。このため、掻寄架台の往復動の距離が短くされると共に、この連結手段により、堆積物用掻寄羽根の揺動を機械的に浮上物用掻寄羽根に伝達して浮上物用掻寄羽根を水面から出没させる連動機構が減少される。   When such a configuration is adopted, each of the deposited scraping blades arranged in parallel swings and mechanically interlocks with the swing of at least one depositing scraping blade. The floating blade for floating object that forms a pair with the scraping blade appears and disappears from the surface of the water, and other floating blades for floating object that are arranged in parallel with the rising and falling of the scraping blade for floating object are connected to the surface of the water by the connecting means. The deposits and floating objects are distributed by the parallel scraping blades and are sequentially scraped to the next scraping blade. For this reason, the distance of the reciprocating motion of the scraping base is shortened, and by this connecting means, the swinging of the deposit scraping blade is mechanically transmitted to the floating scraping blade and the floating scraping blade. The interlocking mechanism that causes the water to appear and disappear from the water surface is reduced.

このように本発明による堆積物及び浮上物の掻寄装置によれば、浮上物用掻寄羽根のための動力が不要で低コスト化が図られると共に、堆積物及び浮上物の掻き戻しが無く堆積物及び浮上物が効率的且つ確実に掻き寄せられ、加えて、水面下の堆積物用掻寄羽根の動きが、当該堆積物用掻寄羽根の揺動に機械的に連動して水面から出没する浮上物用掻寄羽根の動きにより確認され信頼性が向上される。   As described above, according to the deposit and levitated scraping device according to the present invention, power for the levitating scraping blade is not required and the cost is reduced, and there is no scraping of the deposit and levitated object. Sediment and levitated materials are scraped efficiently and reliably, and in addition, the movement of the scraping blade for sediment below the surface of the water is mechanically interlocked with the swing of the scraping blade for sediment from the surface of the water. This is confirmed by the movement of the scraping blades for floating objects that appear and appear, and the reliability is improved.

以下、本発明による堆積物及び浮上物の掻寄装置の好適な実施形態について図1〜図9を参照しながら説明する。   DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of a deposit and levitated scraping device according to the present invention will be described with reference to FIGS.

A pair of connecting shafts 11 extending in the reciprocating direction and spaced apart in the width direction of the tank 10 connects the upper portions of the plurality of frames 37. Adjacent scum posts 2 are connected to each other via intersecting tie rods 14 in order to increase rigidity.

枠体29の連結軸11には、図1及び図3に示すように、スカムバー13との連結位置から往復動方向に所定距離離間した位置に、図3及び図6に示すように、固定軸4が側壁10cに向かうように連結されている。   As shown in FIGS. 1 and 3, the connecting shaft 11 of the frame body 29 has a fixed shaft as shown in FIGS. 3 and 6 at a position separated from the connecting position with the scum bar 13 by a predetermined distance in the reciprocating direction. 4 are connected to the side wall 10c.

この固定軸4には、図3及び図6に示すように、スカムプレート15を主体として備える浮上物掻寄部(揺動部)8が、揺動可能に設けられている。この浮上物掻寄部8は、固定軸4に外挿され揺動可能に支持されるパイプ5と、このパイプ5にスカムプレート取付板6を介して連結されたスカムプレート15と、を備えている。このスカムプレート15は、図2に示すように、槽10の水面3の幅と略同一の幅となるように構成され、剛性を高めるべく、図6に示すように、断面形状が略L字形とされている。   As shown in FIGS. 3 and 6, the fixed shaft 4 is provided with a floating object scraping portion (swinging portion) 8 mainly including a scum plate 15 so as to be swingable. The levitated scraping portion 8 includes a pipe 5 that is externally attached to the fixed shaft 4 and supported so as to be swingable, and a scum plate 15 that is connected to the pipe 5 via a scum plate mounting plate 6. Yes. As shown in FIG. 2, the scum plate 15 is configured to have substantially the same width as the width of the water surface 3 of the tank 10, and the cross-sectional shape is substantially L-shaped as shown in FIG. It is said that.

連動機構9は、図3及び図6に示すように、スカムプレート15を備える浮上物掻寄部8と、この浮上物掻寄部8とフライトアーム(フライト12の揺動部分)25とを繋ぐワイヤ18と、このワイヤ18を常時張るように浮上物掻寄部8に設けられたカウンタウエイト17と、を具備している。ワイヤ18は、その上端部が、第二アーム19を介して浮上物掻寄部8のパイプ5と接続され、その下端部が、図3及び図4に示すように、第一アーム26を介してフライトアーム25と接続されている。第二アーム19は、図6に示すように、スカムプレート15に対して図示時計回りに所定の角度を成すようにパイプ5に取り付けられている。   As shown in FIGS. 3 and 6, the interlocking mechanism 9 connects the levitated object scraping portion 8 including the scum plate 15, and the levitated object scraping portion 8 and the flight arm (the swinging portion of the flight 12) 25. A wire 18 and a counterweight 17 provided on the levitated scraping portion 8 so as to always stretch the wire 18 are provided. The upper end portion of the wire 18 is connected to the pipe 5 of the levitated scraping portion 8 via the second arm 19, and the lower end portion thereof is connected to the first arm 26 as shown in FIGS. 3 and 4. And connected to the flight arm 25. As shown in FIG. 6, the second arm 19 is attached to the pipe 5 so as to form a predetermined angle clockwise with respect to the scum plate 15.

カウンタウエイト17は、図3及び図6に示すように、カウンタウエイトアーム16を介してパイプ5に接続され、このカウンタウエイト17により、ワイヤ18が常時引っ張られる方向に回転モーメントが付与されている。そして、これらのスカムプレート15及びカウンタウエイト17を備える浮上物掻寄部8、ワイヤ18等により構成される連動機構9により、図1及び図3に示すように、フライト12とスカムプレート15が機械的に連動する。このスカムプレート15は、フライト12を第一の揺動位置に垂下させた状態の時に、水面3下に水没した状態とされている。   As shown in FIGS. 3 and 6, the counterweight 17 is connected to the pipe 5 via the counterweight arm 16, and a rotational moment is applied to the counterweight 17 in a direction in which the wire 18 is always pulled. Then, the interlocking mechanism 9 including the scum plate 15 and the floating object scraping portion 8 provided with the counterweight 17, the wire 18 and the like causes the flight 12 and the scum plate 15 to be machined as shown in FIGS. Work together. The scum plate 15 is submerged under the water surface 3 when the flight 12 is suspended from the first swing position.

また、本実施形態にあっては、掻寄架台20の往復動方向に複数並設されたスカムプレート15の動作を互いに連動させる連結手段を備えている。この連結手段は、図6、図8及び図9に示すように、パイプ5に固定された連結アーム34と、この連結アーム34の端部を貫通し当該連結アーム34を揺動可能に支持するピン41と、このピン41の両端部を支持する連結部材40と、このピン41の連結部材40からの抜け止めとしての止め輪42と、を具備し、図8及び図9に示すように、連結部材40の往復動方向の両側には連結棒38が接続され、この連結棒38を介して掻寄架台20の往復動方向に隣接する連結アーム34同士が連結されている。これにより、図1に示すように、各々の浮上物掻寄部8が互いに連動する。   Further, in the present embodiment, there is provided connecting means for interlocking the operations of a plurality of scum plates 15 arranged side by side in the reciprocating direction of the scraper 20. As shown in FIGS. 6, 8 and 9, the connecting means includes a connecting arm 34 fixed to the pipe 5 and an end of the connecting arm 34 so as to swingably support the connecting arm 34. A pin 41, a connecting member 40 that supports both ends of the pin 41, and a retaining ring 42 for preventing the pin 41 from coming off from the connecting member 40, as shown in FIGS. A connecting rod 38 is connected to both sides of the connecting member 40 in the reciprocating direction, and the connecting arms 34 adjacent to each other in the reciprocating direction of the scraper 20 are connected to each other via the connecting rod 38. Thereby, as shown in FIG. 1, each floating thing scraping part 8 mutually interlock | cooperates.

さらに、本実施形態にあっては、スカムパイプ7下流側(図示右側)にも、浮上物掻寄部8を備え、連結棒38を介して上流側の浮上物掻寄部8と連結されている。下流側の浮上物掻寄部8は、上流側の浮上物掻寄部8と同様に揺動するが、浮上物を掻き寄せる方向が異なるため、上流側のスカムプレート15が水没している時に、下流側のスカムプレート15が水面3に対して直立し水面3上に現れるように下流側の浮上物掻寄部8に取り付けられている。   Further, in the present embodiment, the levitated object scraping portion 8 is also provided on the downstream side (right side in the drawing) of the scum pipe 7 and connected to the upstream levitated object scraping portion 8 via the connecting rod 38. . The floating surface scraping portion 8 on the downstream side swings similarly to the floating surface scraping portion 8 on the upstream side. However, since the direction in which the floating material is scraped is different, the upstream scum plate 15 is submerged. The downstream scum plate 15 is attached to the downstream floating object scraping portion 8 so as to stand upright with respect to the water surface 3 and appear on the water surface 3.

このように構成された堆積物及び浮上物の掻寄装置1によれば、槽10の底面10bに堆積した堆積物は、上述したように、フライト12による順送りにより、汚泥ピット10aへ掻き寄せられる。   According to the deposit and levitated scraping device 1 configured in this way, the deposit deposited on the bottom surface 10b of the tank 10 is scraped to the sludge pit 10a by the forward feed by the flight 12, as described above. .

この時、図4に示すように、フライト12は第一の揺動位置に位置し、図6に示すように、第二アーム19と所定の角度を成すスカムプレート15は、水没した状態にあり、この状態で掻寄架台20と共に汚泥ピット10aに向かって動くため、スカム等の浮上物はスカムパイプ7の反対側に掻き戻されることは無い。   At this time, as shown in FIG. 4, the flight 12 is located at the first swing position, and as shown in FIG. 6, the scum plate 15 having a predetermined angle with the second arm 19 is in a submerged state. In this state, it moves toward the sludge pit 10 a together with the cradle 20, so that floating objects such as scum are not scraped back to the opposite side of the scum pipe 7.

この移動の際に、スカムプレート15は、掻寄架台20の往動方向に対して、傾斜して水没している。このため、スカムプレート15が水面3に対して略垂直に水没する構成に比して、水面3下に没した状態での移動の際(非掻寄時)の抵抗が少なくされると共に確実に掻き戻しが無くされている。この時、スカムパイプ7の下流側のスカムプレート15は、水面3に出現した状態にあると共に、スカムパイプ7の開口部は下流側を向いている。従って、スカムパイプ7より下流側の浮上物は、スカムパイプ7より下流側のスカムプレート15により、スカムパイプ7へ円滑に排出される。   During this movement, the scum plate 15 is inclined and submerged with respect to the forward movement direction of the scraper 20. For this reason, as compared with the configuration in which the scum plate 15 is submerged substantially perpendicularly to the water surface 3, resistance during movement in a state where the scum plate 15 is submerged under the water surface 3 (when not scraped) is reduced and reliably. There is no scraping. At this time, the scum plate 15 on the downstream side of the scum pipe 7 is in a state of appearing on the water surface 3, and the opening of the scum pipe 7 faces the downstream side. Accordingly, the levitated material downstream of the scum pipe 7 is smoothly discharged to the scum pipe 7 by the scum plate 15 downstream of the scum pipe 7.

次いで、掻寄架台20が復動を始め、フライト12は、図4に示す垂下した第一の揺動位置から図示時計回りに回動し、図5に示すように、底面10bから離間した状態となり、第一アーム26も図示時計回りに回動してワイヤ18を下方に引き寄せる。   Next, the scraper 20 starts to move backward, and the flight 12 is rotated clockwise from the first swung position shown in FIG. 4 and separated from the bottom surface 10b as shown in FIG. Thus, the first arm 26 also rotates clockwise in the drawing to draw the wire 18 downward.

この時、ワイヤ18の下方への移動により、第二アーム19が図6に示す位置から図示時計回りに下方へ回動し、スカムプレート15は、図6に示す水没している位置から、水面3に向かって図示時計回りに回動し、図7に示すように、垂直上向きに直立し、水面3に出現する。さらに、並列されたスカムプレート15は、連結手段により連結されていることから、各々のスカムプレート15は互いに連動して垂直上向きに直立し水面3に出現する。この状態で掻寄架台20が復動を続け、水面3に浮上している浮上物は、水面3上に出現したスカムプレート15により、スカムパイプ7に向かって掻き寄せられる。この時、スカムパイプ7の開口部は上流側を向いている。また、スカムパイプ7より下流側のスカムプレート15は、連結手段により連動して水没した状態にあり、当該スカムパイプ7より下流側の浮上物が、下流側に掻き戻されることは無い。   At this time, due to the downward movement of the wire 18, the second arm 19 is rotated downward from the position shown in FIG. 6 in the clockwise direction, and the scum plate 15 is moved from the position shown in FIG. As shown in FIG. 7, it turns upright vertically and appears on the water surface 3. Furthermore, since the scum plates 15 arranged in parallel are connected by the connecting means, the scum plates 15 stand up vertically upward in conjunction with each other and appear on the water surface 3. In this state, the cradle 20 continues to move back, and the levitated object floating on the water surface 3 is scraped toward the scum pipe 7 by the scum plate 15 that has appeared on the water surface 3. At this time, the opening of the scum pipe 7 faces the upstream side. Further, the scum plate 15 on the downstream side of the scum pipe 7 is in a state of being submerged in conjunction with the connecting means, and the levitated material on the downstream side of the scum pipe 7 is not scraped back to the downstream side.

そして、さらに掻寄架台20は復動を続け、図5に示すように、フライト12の先端が復動側に隣接する開口部44を通過した後、再び、往動を始める。フライト12は、図5に示す図示時計回りに回動した位置から、図示反時計回り回動して、図4に示す垂下した第一の揺動位置に復帰し、第一アーム26も図示反時計回りに回動する。これにより、ワイヤ18を下方に引き寄せていた力が緩和される。   Further, the scraping base 20 continues to move backward, and as shown in FIG. 5, after the front end of the flight 12 passes through the opening 44 adjacent to the backward movement side, it starts moving forward again. The flight 12 is rotated counterclockwise in the figure from the position rotated clockwise in FIG. 5 and returned to the suspended first swing position shown in FIG. 4, and the first arm 26 is also illustrated in FIG. Rotate clockwise. Thereby, the force which pulled the wire 18 downward is relieved.

従って、図7に示すように、カウンタウエイトアーム16は下方へ回動し、浮上物掻寄部8は、スカムプレート15が水面3に出現している状態から図示反時計回りに回動し、図6に示すように水没する。さらに、並列されたスカムプレート15は、各々が連結手段により連結されているため、各々のスカムプレート15は互いに連動して水没する。一方、スカムパイプ7より下流側のスカムプレート15は、連動して水面3上に出現する。このような一連のスカムプレート15の動作により、浮上物は、所定区間毎に一つのスカムプレート15で順送りされ、スカムパイプ7迄掻き寄せられて円滑に排出される。   Accordingly, as shown in FIG. 7, the counterweight arm 16 is rotated downward, and the levitated scraping portion 8 is rotated counterclockwise from the state in which the scum plate 15 appears on the water surface 3, As shown in FIG. Further, since the scum plates 15 arranged in parallel are connected by the connecting means, the scum plates 15 are submerged in conjunction with each other. On the other hand, the scum plate 15 on the downstream side of the scum pipe 7 appears on the water surface 3 in conjunction with it. By such a series of operations of the scum plate 15, the levitated material is sequentially fed by one scum plate 15 every predetermined section, and is scraped up to the scum pipe 7 and discharged smoothly.

このように、本実施形態においては、堆積物及び浮上物掻寄装置1が水面3に浮上したスカム等の浮上物を掻き寄せるスカムプレート15を備えると共に、フライト12の揺動に機械的に連動してスカムプレート15を槽10の水面3から出没させる連動機構9を備えているため、上記フライト12による堆積物の掻き戻しが無いことに加えて、スカムプレート15による浮上物の掻き戻しが無く、堆積物及び浮上物が円滑に掻き寄せられて排出されると共に、スカムプレート15のための動力源を別途設置する必要が無くされている。このため、低コスト化が図られると共に、堆積物及び浮上物が効率的且つ確実に掻き寄せられ、加えて、水面3下のフライト12の動きが、当該フライト12の揺動に機械的に連動して水面3から出没するスカムプレート15の動きにより確認され信頼性が向上されている。   As described above, in the present embodiment, the deposit and floating material scraping device 1 includes the scum plate 15 that scrapes the floating material such as the scum that floats on the water surface 3 and mechanically interlocks with the swing of the flight 12. Since the interlocking mechanism 9 for moving the scum plate 15 in and out of the water surface 3 of the tank 10 is provided, in addition to the deposit 12 not being raked back by the flight 12, there is no rake back of the levitated matter by the scum plate 15. In addition, the deposits and floating objects are smoothly scraped and discharged, and it is not necessary to separately install a power source for the scum plate 15. For this reason, the cost is reduced and the deposits and floating objects are scraped efficiently and reliably. In addition, the movement of the flight 12 below the water surface 3 is mechanically linked to the swing of the flight 12. Thus, the reliability is improved as confirmed by the movement of the scum plate 15 that appears and disappears from the water surface 3.

また、図1に示すように、例えば汚泥等を含む排水等が槽10内に供給されると、汚泥等の堆積物はその多くが上流側(図示左側)に堆積し、浮上物は流れに乗って槽10の下流側へと向かうが、堆積物の排出位置として汚泥ピット10aを槽10の上流側に設定し、浮上物の排出位置としてスカムパイプ7を槽の下流側に設定しているため、堆積物は汚泥ピット10aへ、浮上物はスカムパイプ7へ一層効果的に掻き寄せられる。   Further, as shown in FIG. 1, for example, when drainage containing sludge or the like is supplied into the tank 10, most of the sediment such as sludge accumulates on the upstream side (the left side in the drawing), and the floating matter flows. Although it rides toward the downstream side of the tank 10, the sludge pit 10a is set on the upstream side of the tank 10 as the deposit discharge position, and the scum pipe 7 is set on the downstream side of the tank as the discharge position of the levitated matter. The sediment is scraped to the sludge pit 10a, and the levitated matter is scraped to the scum pipe 7 more effectively.

また、複数のフライト12を備え、各々のフライト12がこの一連の動作によって揺動されると共に、このフライト12の各々の揺動に機械的に連動して、並列するスカムプレート15の各々が水面3から出没し、堆積物、浮上物は、並列するフライト12、スカムプレート15により分担して次のフライト12、スカムプレート15へと順々に掻き寄せられるため、一つのフライト12、スカムプレート15で槽10全体の掻き寄せを行う場合に比して、掻寄架台20の往復運動の距離が短くされている。   Each of the flights 12 is provided with a plurality of flights 12, and each of the flights 12 is oscillated by this series of operations, and each of the scum plates 15 arranged in parallel is mechanically interlocked with each oscillation of the flight 12. 3, the deposits and levitated matter are shared by the parallel flight 12 and scum plate 15 and scraped sequentially to the next flight 12 and scum plate 15, so that one flight 12 and scum plate 15 In comparison with the case where the entire tank 10 is scraped, the distance of the reciprocating motion of the cradle 20 is shortened.

また、スカムプレート15が、スカムパイプ7の下流側にも設置されているため、スカムパイプ7より下流側で浮上した浮上物も良好に掻き寄せられる。   Further, since the scum plate 15 is also installed on the downstream side of the scum pipe 7, the levitated objects that have floated on the downstream side of the scum pipe 7 are also scraped well.

また、スカムパイプ7は回転自在とされ、スカムプレート15が浮上物を掻き寄せる方向に応じて、スカムパイプ7の開口部の向きが変えられているため、スカムパイプ7に流入する表面水の量が減らされ、後段のスカム移送ポンプ(不図示)等の運転コスト等を削減することが可能とされている。   Further, the scum pipe 7 is rotatable, and the direction of the opening of the scum pipe 7 is changed according to the direction in which the scum plate 15 scrapes the floating object, so that the amount of surface water flowing into the scum pipe 7 is reduced. In addition, it is possible to reduce operating costs and the like of the subsequent scum transfer pump (not shown).

また、浮上物掻寄部8が枠体29を介して掻寄架台20と連結され、浮上物掻寄部8と掻寄架台20とが一体となって移動するため、浮上物掻寄部8専用のガイドレール等を設置する必要が無く、制作費、現地工事費等を抑えることが可能とされている。   In addition, the levitated object scraping portion 8 is connected to the raking base 20 via the frame 29, and the levitated object scraping portion 8 and the raking base 20 are moved together. There is no need to install dedicated guide rails, etc., making it possible to reduce production costs and local construction costs.

また、チェーンフライト式汚泥掻寄機は、フライト(堆積物用掻寄羽根)の戻り部を利用して水面3の浮上物を掻き寄せているため、図2に示すように、槽10の底面10bの幅と比較して水面3の幅が大きい場合は、側壁10c付近の浮上物を掻き寄せることが無理であるか、又は、対策として特開平8−267059号公報記載のように、フライトと槽10の側壁10cとの間の隙間を塞ぐためのスカムガイドを、側壁10cの略全長に亘り設置する必要があるが、本実施形態の堆積物及び浮上物の掻寄装置1は、フライト12とスカムプレート15とは別部品とされているため、前述したようにスカムプレート15の幅が水面3の幅と略同一とされ、スカムガイドを設置すること無く、側壁10c際の浮上物を効果的に掻き寄せることが可能とされている。   Moreover, since the chain flight type sludge scraping machine uses the return part of the flight (scraping blade for deposits) to scrape the floating material on the water surface 3, as shown in FIG. When the width of the water surface 3 is larger than the width of 10b, it is impossible to scrape the floating object near the side wall 10c, or as a countermeasure, as described in JP-A-8-267059, It is necessary to install a scum guide for closing the gap between the side wall 10c of the tank 10 over substantially the entire length of the side wall 10c. Since the scum plate 15 and the scum plate 15 are separate parts, the width of the scum plate 15 is substantially the same as the width of the water surface 3 as described above, and the floating object at the side wall 10c can be effectively obtained without installing the scum guide. Raked in It is possible.

ここで、特開平8−267059号公報記載のチェーンフライト式汚泥掻寄機では、水面3を移動するフライトがスカムパイプ7の手前で、水面3に対して斜めに傾斜して水没するため、フライトを水面3に対して直立させた状態でスカムパイプ7に近づけることは無理であるが、本実施形態の堆積物及び浮上物の掻寄装置1では、スカムプレート15が水面3に対して直立した状態でスカムパイプ7に可能な限り接近され、特開平8−267059号公報記載の装置に比して、浮上物の掻き寄せ及び排出が確実に行われる。   Here, in the chain flight type sludge scraper described in JP-A-8-267059, the flight moving on the water surface 3 is submerged obliquely with respect to the water surface 3 in front of the scum pipe 7, Although it is impossible to approach the scum pipe 7 while standing upright with respect to the water surface 3, in the scraping device 1 for deposits and floating objects according to the present embodiment, the scum plate 15 is upright with respect to the water surface 3. As close as possible to the scum pipe 7, the levitated material is scraped and discharged more reliably than the apparatus described in Japanese Patent Laid-Open No. 8-26759.

以上、本発明をその実施形態に基づき具体的に説明したが、本発明は、上記実施形態に限定されるものではない。例えば、連結棒38により、複数の連結アーム34が互いに連結され、複数のスカムプレート15が機械的に連動するため、ワイヤ18による連結箇所は、1以上であれば限定されない。   As mentioned above, although this invention was concretely demonstrated based on the embodiment, this invention is not limited to the said embodiment. For example, since the plurality of connecting arms 34 are connected to each other by the connecting rod 38 and the plurality of scum plates 15 are mechanically interlocked, the number of connecting portions by the wires 18 is not limited as long as it is one or more.

また、スカムプレート15の連結軸11に対する設置位置は、スカムプレート取付板6、カウンタウエイトアーム16、第二アーム19、連結アーム34の角度を変えることにより、自由に選定することが可能である。   The installation position of the scum plate 15 with respect to the connecting shaft 11 can be freely selected by changing the angles of the scum plate mounting plate 6, the counterweight arm 16, the second arm 19, and the connecting arm 34.

また、上記実施形態においては、特に好ましいとして、スカムプレート15が揺動することで水面3から出没する構成としているが、スカムプレート15が略垂直に移動し、水面から略垂直に出没する構成とすることも可能である。   Further, in the above-described embodiment, as a particularly preferable configuration, the scum plate 15 swings and protrudes from the water surface 3. However, the scum plate 15 moves substantially vertically and protrudes and protrudes from the water surface approximately vertically. It is also possible to do.

なお、上記実施形態では、各々のフライトアーム25に副ローラ27を設置して、フライト12を揺動させる構造としているが、副ローラ27の設置個数を1個以上とし、スカムプレート15を連動させる連結手段のように、連結棒等を互いに接続することにより、並列するフライトアーム25同士を機械的に連動させる構造としても良い。このような構造とした場合、副ローラ27及び副ローラ27の動きに寄与しない案内フラップ35,36の数量が減少され、低コスト化及び簡素化が可能となる。   In the above embodiment, the sub-rollers 27 are installed on each flight arm 25 to swing the flight 12, but the number of sub-rollers 27 installed is one or more and the scum plate 15 is interlocked. It is good also as a structure which mechanically interlocks the parallel flight arms 25 by connecting a connecting rod etc. mutually like a connection means. In the case of such a structure, the number of the guide flaps 35 and 36 that do not contribute to the movement of the auxiliary roller 27 and the auxiliary roller 27 is reduced, and the cost can be reduced and simplified.
