Description

  The present invention relates to a transfer device for transferring an object to be transferred that has floated on a water surface.

  A transfer device for transferring an object to be transferred such as scum floating on the water surface toward a scum pit or the like is provided in a water basin or a sedimentation basin of a sewage treatment plant (see, for example, Patent Document 1).

  FIG. 13 is a schematic view of the transfer device described in Patent Document 1 as viewed from above. The transfer device 6 described in Patent Document 1 includes a plurality of spray nozzles 61 provided about 100 mm to 200 mm above the surface of the sewage in the water conduit 9 in which the sewage flows from the left side to the right side of the drawing. ing. The plurality of spray nozzles 61 are arranged at a predetermined interval in the width direction (vertical direction in FIG. 13) of the water conduit 9 and are directed from the left side to the right side in the transfer direction of the scum Sc (object to be transferred). (Direction) is also arranged in a plurality of rows at a predetermined interval. In the transfer device 6 described in Patent Document 1, pressure water or air is discharged from a plurality of spray nozzles 61 substantially horizontally in the transfer direction toward a scum pit or the like (not shown). As a result, an air flow or blowing flow toward the scum pit is generated on the water surface, and the scum floating on the water surface is transferred toward the scum pit or the like by this air flow or the like.

Japanese Patent Laid-Open No. 7-303883

  However, in the transfer device 6 described in Patent Document 1, the pressure water or the like discharged from the spray nozzle 61 diffuses, and it is difficult to generate an airflow or the like that can transfer the transfer object over a wide range on the water surface. . For this reason, in FIG. 13, as shown by the white circle surrounded by the one-dot chain line, the range in which the pressure water or the like discharged from the spray nozzle 61 can take effect is indicated by one spray nozzle 61 (the scum Sc). ) Will be limited on the water surface. As a result, a large number of spray nozzles 61 are arranged on the surface of the water where the scum Sc floats (in the figure, the scum floating on the surface of the water is marked with Sc0) at intervals. In addition, the apparatus becomes large because, for example, a large number of pipes 62 for supplying pressure water or the like to the large number of spray nozzles 61 are required. In addition, a large amount of pressure water or the like discharged from a large number of spray nozzles 61 is required. Moreover, in the aspect which discharges air from the spray nozzle 61, the scum Sc may be dried and hardened by the discharged air. Since the scum Sc that has been hardened in this way becomes difficult to move on the water surface, there is a problem that more air must be discharged.

  In view of the above circumstances, an object of the present invention is to provide a transfer device that can reduce the amount of fluid to be discharged and can transfer an object to be transferred suspended on a water surface with a simple structure.

The transfer device of the present invention that solves the above-mentioned object forms a flow path, and is provided with a flow path forming member provided with a suction port connected to the flow path and immersed in water,
A discharge port for discharging fluid into the flow path;
The suction port functions as an opening for sucking a transferred object floating on the water surface into the flow path by discharging a fluid into the flow path.
The flow path functions as a path through which the transferred object sucked into the flow path moves toward the downstream side in the fluid discharge direction when the fluid is discharged into the flow path. It is characterized by that.

  Here, the flow path forming member may be one in which the suction port opens from a position lower than the water surface toward the water surface and is located at a depth within 200 mm from the water surface. In addition, the said flow path formation member may be what the said suction inlet opened toward directions other than the said water surface. Further, when the height of the water surface changes, the flow path forming member may move in a vertical direction and change the height of the suction port. Furthermore, the flow path may be such that a portion on the suction port side becomes narrower as it approaches the suction port. The flow path forming member may have a shape in which a part of a cylindrical body is cut out. Further, the discharge port may be a perfect circle or a flat shape, and a plurality of the discharge ports may be provided at intervals in the discharge direction. Furthermore, the fluid discharged from the discharge port may be a liquid, a gas, or a gas-liquid mixture. The discharge port may discharge a fluid of 300 liters to 3000 liters per minute at a pressure of 0.3 MPa or less.

  According to the transfer device of the present invention, when the fluid is discharged from the discharge port into the flow path, the transferred object drawn into the flow of the discharged fluid and floating on the water surface is It is sucked into the flow path from the mouth. Further, in the flow path, the sucked object to be transferred moves toward the downstream side in the discharge direction by the flow of water generated by the fluid. Thus, the flow of water once generated in the flow path is much more than the air flow and the blowing flow in the transfer device described in Patent Document 1 because the flow path is surrounded by the flow path forming member. It is difficult to attenuate, and the transferred object can be transferred for a long distance. Furthermore, a flow in the direction of being sucked into the suction port is generated on the water surface, and the transferred substance floating on the water surface can be sucked into the flow path in a wide range.

  Furthermore, the flow in the direction of being sucked into the suction port on the water surface may cause a region where the transferred object is removed on the water surface to extend in the transfer direction. Hereinafter, the region on the water surface from which the transferred object is removed may be referred to as a water surface removal region. When the transfer device is installed in a water conduit or the like, for example, when the received sewage flows in the transfer direction, a flow in the transfer direction is also generated on the water surface due to the flow of the received sewage. ) Also flows in the removal direction of the water surface in the transport direction. Further, when the scum flowing through the water surface removal area comes into contact with the scum floating on the water surface, a part of the scum collapses, and the collapsed part is sucked from the suction port and is absorbed in the flow path. Or move in the transfer direction by flowing through the removal area of the water surface. As a result, the scum that is floating on the surface of the water can be efficiently transferred while being broken little by little.

  Accordingly, the number of the discharge ports and the piping for supplying fluid to the discharge ports can be reduced, and a simple structure can be adopted. Furthermore, the amount of fluid discharged from the discharge port can also be suppressed. In addition, as described above, since the flow of water only has to be once generated in the flow path, the pressure of the fluid discharged from the discharge port may be sufficient even if it is a weak pressure of 0.1 MPa or less. .

  In the transfer device of the present invention, the flow path forming member may have a flat shape in which the dimension in the width direction orthogonal to the fluid discharge direction in the horizontal plane is longer than the dimension in the height direction. .

  As described above, when the flow path forming member having a flat shape is employed, the suction port can be easily widened in the width direction. If the suction port is widened in the width direction, the transferred object floating in a wider area of the water surface can be sucked into the flow path. Further, by forming the flow path forming member into a flat shape, the entire apparatus can be made thin, and can be suitably used for a shallow water channel or the like. Further, by making the flow path forming member flat, it becomes difficult to hinder the flow of sewage such as a waterway provided with the transfer device, and the resistance to the flow of sewage can be reduced. .

Furthermore, in the transfer device according to the present invention, in the water, a peripheral region around the flow path forming member and other regions are partitioned so that the peripheral region is on the inside, and an inflow port connected to the peripheral region is provided. A partition member,
The inflow port functions as an opening for allowing the transferred object floating on the water surface to flow into the peripheral region by discharging a fluid into the flow path.
The suction port may function as an opening for sucking the transferred object that has flowed into the peripheral region into the flow path by discharging a fluid into the flow path.

  Here, the partition member may be one in which the inflow port opens from a position lower than the water surface toward the water surface and is located at a depth within 200 mm from the water surface. Moreover, when the height of the said water surface changes, the said partition member may move to a perpendicular direction, and can change the height of the said suction inlet. Further, the peripheral area may be such that a portion on the inlet side becomes narrower as the inlet is closer to the inlet. Further, the partition member may have a curved portion that enters the center side in the width direction at the upper end portion. Further, in the flow path forming member, the suction port is opened in the peripheral region, and the upper end portion is located at substantially the same height as the inflow port, the lower position is lower than the inflow port, or Any of those located above the inlet may be used. Further, the partition member may have a shape in which the upper end portion of the cylindrical body is cut out. Furthermore, the partition member and the flow path forming member may be configured by a curved surface having an inner peripheral surface extending from the partition member to the flow path forming member. In addition, the flow path forming member has a part in common with a part of the partition member in a state of being separated from the other end side of the partition member at one end side and the other end side in the width direction. It may be connected to the one end side.

  If the aspect provided with the partition member is adopted, since the peripheral region is partitioned from other regions by the partition member in water, the inflow of the transferred object from the inflow port into the peripheral region is prevented. The transferred object that is promoted and floated on the water surface can efficiently flow into the peripheral region. Furthermore, since the peripheral area is partitioned by the partition member with another area, the flow of water from the inflow port to the suction port is not hindered, and the transferred object that has flowed into the peripheral area Flows through the peripheral region and is smoothly sucked from the suction port.

  In addition, when the transfer device is provided in a water conduit or the like, the received water flows in the transfer direction. For example, the scum (transfer object) flows in the removal direction of the water surface in the transfer direction due to the flow of the received water. . In addition, the scum flowing through the water surface removal region collapses by contacting the scum staying in a state of being gathered on the water surface, and the collapsed portion flows into the peripheral region from the inflow port. Then, it is sucked from the suction port and moves in the flow path, or flows in the removal direction of the water surface and moves in the transfer direction. As a result, the scum staying on the surface of the water can be efficiently transferred while being gradually broken.

  In the transfer device of the present invention, the partition member may have a flat shape in which the dimension in the width direction orthogonal to the fluid discharge direction in the horizontal plane is longer than the dimension in the height direction.

  As described above, when the flat partition member is employed, it is easy to widen the inflow port in the width direction. If the inlet is widened in the width direction, the object to be transported floating in a wider area of the water surface can be allowed to flow into the peripheral region. Moreover, the whole apparatus can be made thin by making the said partition member into a flat shape, It can use suitably also for a shallow water channel. Furthermore, by making the partition member into a flat shape, it becomes difficult to hinder the flow of sewage and the like in the water conduit provided with the transfer device, and the resistance to the flow of sewage and the like can be reduced.

  Furthermore, the transfer device of the present invention may be movable in a direction orthogonal to the fluid discharge direction in a horizontal plane.

  By doing so, the object to be transported floating in a wider area on the water surface can be introduced into the peripheral region from the inflow port and transferred without increasing the number of the transfer devices.

  ADVANTAGE OF THE INVENTION According to this invention, the transfer apparatus which can suppress the quantity of the fluid to discharge and can transfer the to-be-transferred object which floated on the water surface by simple structure can be provided.

It is CC sectional view taken on the line of the overhang pipe shown in FIG. It is the schematic diagram of a mode that the transfer apparatus of patent document 1 was seen from upper direction.

  Embodiments of the present invention will be described below with reference to the drawings. The transfer device of the present invention can be adopted in various facilities and structures for transferring an object to be transported floating on the water surface, such as a diversion basin or a sedimentation basin in a sewage treatment plant, or an overhang structure of a sewage pipe. It can be suitably applied to. In the present embodiment, description will be made by taking as an example a transfer device that transfers scum that is provided in the water basin of the first sedimentation basin or the final sedimentation basin and floats on the water surface. That is, in the present embodiment, the scum corresponds to an example of the transferred object. The headrace is a water channel that distributes sewage received from a settling basin, an aeration tank, or the like at a sewage treatment plant to a plurality of settling basins, and scum floating on the water surface is collected in a scum pit.

  FIG. 1 is a plan view of a water conduit provided with a transfer device according to an embodiment of the present invention as viewed from above, and FIG. 2 is a cross-sectional view of the water conduit shown in FIG. In addition, in FIG. 1, some of the several sedimentation basins P in which dirty water is distributed from the water conduit 9 are also shown.

  As shown in FIG. 1, the water conduit 9 is a rectangular water channel that is long in the left-right direction when viewed from above, and a water flow portion 91 that receives sewage sent from a sand basin (not shown), and the water flow portion 91. Has a scum pit 92 partitioned by a blocking wall 93. The flowing water portion 91 receives sewage from the left side of the figure, and the received sewage flows toward the scum pit 92 provided on the right side of the figure and is blocked by the blocking wall 93. In addition, a plurality of sedimentation basins P arranged in parallel in the direction in which sewage flows through the flowing water portion 91 are connected to the flowing water portion 91 through a communication port 94. The sewage flowing through the flowing water portion 91 is distributed by flowing into each sedimentation basin P from each communication port 94, and the sewage flowing into each sedimentation basin P flows downward in the figure.

  As shown in FIG. 1 and FIG. 2, the water flow section 91 is provided with a transfer device 1. Before the transfer device 1 is driven, the scum Sc floats in the entire area of the water surface WL (see FIG. 2) of the sewage W in the flowing water portion 91. In FIGS. 1 and 2, as will be described in detail later, water is discharged from the discharge port 7 a of the transfer device 1, so that the scum Sc is transferred to the right side of the drawing and collected in the vicinity of the blocking wall 93. It shows a state. That is, the scum Sc is transferred in the longitudinal direction of the flowing water portion 91. In FIGS. 1 and 2, the direction from the left to the right corresponds to the discharge direction in which fluid is discharged, and the transfer direction in which the scum Sc is transferred. It corresponds to. In addition, the short direction of the flowing water part 91, that is, the direction orthogonal to the discharge direction in the horizontal plane may be hereinafter referred to as a width direction.

  The blocking wall 93 is formed with an opening 93a communicating with the scum pit 92, and a gate 931 for closing the opening 93a is provided. The gate 931 can slide, for example, up and down and open and close the opening 93a. When the gate 931 is slid so that the upper end of the gate 931 is positioned below the water surface WL of the sewage W blocked by the blocking wall 93, the scum Sc collected in the vicinity of the blocking wall 93 becomes sewage. At the same time, it passes over the gate 931 from the opening 93a and flows into the scum pit 92. The scum collected in the scum pit 92 is sent to a scum processing machine (not shown) and subjected to predetermined processing such as dehydration processing.

  Then, the transfer apparatus 1 is demonstrated in detail using FIGS. 1-3.

  FIG. 3 is a cross-sectional view of the transfer device 1 shown in FIG. In FIG. 3, the direction toward the front side of the paper is the ejection direction, and the left-right method is the width direction.

  As shown in FIGS. 1 to 3, the transfer device 1 includes a partition member 3, a flow path forming member 5, and a discharge member 7. As shown in FIGS. 1 and 2, the partition member 3 extends in the discharge direction in the flowing water portion 91, and the total length is slightly shorter than the length of the flowing water portion 91 in the longitudinal direction. . Further, the partition member 3 extends in parallel or substantially parallel to the ejection direction as shown in FIG. 1, and extends horizontally or substantially horizontally as shown in FIG. As shown in FIG. 3, in the sewage W flowing through the flowing water portion 91, the partition member 3 includes the peripheral region R1 around the flow path forming member 5 and the other region R2 such that the peripheral region R1 is inside. It has an inflow port 3a that is connected to the peripheral region R1 and sinks into the sewage W. The partition member 3 of the present embodiment has a circular arc shape in which approximately 1/3 of the upper part of a stainless steel cylindrical body having a diameter of 300 mm or more and 400 mm or less is cut out. An open inflow port 3a is formed. The opening length L3 (see FIG. 4A) in the width direction of the inflow port 3a is set to 275 mm or more and 375 mm or less. Moreover, the partition member 3 has the curved part 31 which entered the center side of the width direction in the upper end part, and peripheral region R1 is so narrow that the part by the side of the inflow port 3a approaches the inflow port 3a. .

  As shown in FIG. 1 and FIG. 2, the flow path forming member 5 extends in the discharge direction in the flowing water portion 91, similarly to the partition member 3, and its entire length is substantially the same as that of the partition member 3. Is formed. Further, the flow path forming member 5 also extends in parallel or substantially parallel to the discharge direction as shown in FIG. 1, and extends horizontally or substantially horizontally as shown in FIG. As shown in FIG. 3, the flow path forming member 5 forms a flow path S, and partitions the flow path S and the peripheral region R1. Further, the flow path forming member 5 has a suction port 5 a that is connected to the flow path S and sinks into the sewage W. The flow path forming member 5 of the present embodiment has a circular arc shape in which approximately 1/6 of a lower portion of a stainless steel cylindrical body having a diameter of 150 mm or more and 200 mm or less is cut out. A suction port 5a that opens toward the top is formed. The flow path forming member 5 is attached to the partition member 3 by a mounting member (not shown) so that the suction port 5a is opened in the peripheral region R1 and the upper end portion 51 is substantially the same height as the inflow port 3a. Yes. In the present embodiment, the radial center of the flow path forming member 5 (conceptually shown with a symbol O in the drawing) is made to coincide with the radial center of the partition member 3. Therefore, the radial distance Di (about 75 mm in this embodiment) between the partition member 3 and the flow path forming member 5 is substantially the same at any location.

  The discharge member 7 has a water supply pipe 70 connected to the rear end portion thereof, and has a discharge port 7a at a tip portion thereof. As shown in FIG. 2, the discharge port 7a is a flow path from the upstream side in the discharge direction. It is inserted into the forming member 5 (flow path S). The water supplied to the discharge member 7 from the water supply pipe 70 is discharged from the discharge port 7a in the horizontal direction or the substantially horizontal direction (refer to the solid line rightward arrow in FIG. 2). In this embodiment, the discharge pressure of the water discharged from the discharge port 7a is set to 0.3 MPa or less. As will be described in detail later, it is sufficient that the flow of water once occurs in the flow path S. Therefore, the pressure of the water discharged from the discharge port 7a may be sufficient even if it is 0.1 MPa or less. . The flow rate of water discharged from the discharge port 7a is adjusted to 300 liters or more and 3000 liters or less per minute. Here, the water discharged from the discharge port 7a may be sewage or tap water received in the sewage treatment plant. Further, a gas other than water or a fluid such as a gas-liquid mixture may be discharged from the discharge port 7a.

  The discharge member 7 of the present embodiment is such that a long-hole-shaped discharge port 7a is formed at the tip of the round pipe-shaped water supply pipe by flattening the tip. Thus, if the aspect which crushes a round pipe into flat shape and forms the discharge outlet 7a is employ | adopted, the manufacture will become easy. Further, as shown in FIG. 3, the opening length L1 in the width direction of the discharge port 7a is set longer than the opening length L2 in the width direction of the suction port 5a. Specifically, in the present embodiment, the opening length L2 in the width direction of the suction port 5a is about 100 mm, the opening length L1 in the width direction of the discharge port 7a is about 120 mm, and the height H1 of the discharge port 7a is about 20 mm. It is. By making the discharge port 7a such a flat shape, it is possible to ensure a wider range in which the flow velocity is higher than that of a perfect circle shape. In some cases, it may be preferable to adopt a round discharge port 7a by using the round pipe-shaped water supply pipe as it is without crushing the tip portion of the round pipe-shaped water supply pipe.

  Here, since the height of the water surface WL of the flowing water portion 91 varies depending on the amount of sewage received from the sand basin, the height position where the transfer device 1 is provided is set in consideration of the variation in the height of the water surface WL. The Specifically, even when the height of the water surface WL of the flowing water portion 91 fluctuates, the inflow port 3a of the partition member 3 is located at a position lower than the water surface WL and has a depth Dp1 from the water surface WL. Within 200 mm, the center in the height direction of the discharge port 7a has a depth Dp2 from the water surface WL of 50 mm to 300 mm, and the suction port 5a of the flow path forming member 5 has a depth Dp3 of 100 mm to 400 mm from the water surface WL. Is set to fit. Moreover, the inflow port 3a of the partition member 3 is located above the lower end part of the opening part 93a in the blocking wall 93 shown with a dashed-dotted line in FIG.

  Although the position of the transfer device 1 may be fixed, the transfer device 1 as a whole or the partitioning member 3 and the transfer member 1 may be fixed as shown by the double arrows in FIGS. Any one of the flow path forming members 5 may be moved in the vertical direction. By doing so, the position of the inlet 3a and the suction port 5a can be made to follow the fluctuation of the height of the water surface WL, and can be maintained at a certain depth from the water surface WL. The discharge port 7a may be moved in the vertical direction in accordance with the vertical movement of the flow path forming member 5, or the discharge port 7a is fixed and only the flow path forming member 5 is moved in the vertical direction. It is good. Moreover, it is good also as an aspect which fixes the transfer apparatus 1 and controls the quantity of the sewage which the flowing water part 91 receives so that the position of the inflow port 3a and the suction inlet 5a may be maintained to the fixed depth from the water surface WL.

  In the transfer device 1 configured as described above, as shown in FIGS. 1 and 2, the scum Sc is transferred by discharging water from the discharge port 7a. Specifically, when water is discharged from the discharge port 7a into the flow path S of the flow path forming member 5, it is drawn into the flow of the discharged water, and as shown in FIG. 3, from the suction port 5a. A flow of water in the direction of being sucked into the flow path S is generated. Thereby, the flow of water flowing into the peripheral region R1 from the inflow port 3a is generated, and the flow of water toward the suction port 5a is generated in the peripheral region R1. As a result, a flow in the direction of gathering at the inlet 3a of the partition member 3 on the water surface WL of the water flow portion 91 (a flow in the direction toward the inlet 3a occurs on the water surface WL in the vicinity of the inlet 3a. The water is made up by supplementing this).

  1 and 2 schematically show the flow of the scum Sc. The scum floating on the water surface is marked with a symbol Sc0 and thinly shaded, and separated from the scum group Sc0. The scum Sc is surrounded by a one-dot chain line and dark shaded. Part of the scum that floats in a collective manner on the entire surface of the water surface WL (see FIGS. 2 and 3) of the water flow portion 91 is collapsed due to the flow in the direction of gathering at the inflow port 3a. It becomes a lump scum Sc and flows into the peripheral region R1 from the inflow port 3a. By repeating this, as shown in FIG. 1, a region where the scum is removed (removal region on the water surface) is generated on the water surface WL along the extending direction of the partition member 3, that is, the transfer direction. In addition, the scum Sc separated from the scum group Sc0 flows in the removal region on the water surface in the transport direction and collects in the vicinity of the blocking wall 93. In addition, the scum Sc breaks a part of the scum Sc in contact with the scum unit Sc0 in the process of flowing through the removal area on the water surface, and the scum Sc collapsed also flows into the peripheral region R1 from the inflow port 3a. Alternatively, the action of flowing in the removal direction on the water surface in the transfer direction is repeated.

  The scum Sc gathered at the inflow port 3a flows into the peripheral region R1 from the inflow port 3a and flows in the peripheral region R1 toward the suction port 5a, as conceptually shown in FIG. Then, it is sucked into the flow path S from the suction port 5a. Here, when the depth of the suction port 5a from the water surface WL is set to 20 mm or more, it is preferable because the scum Sc can flow more smoothly from the suction port 5a.

  In the sewage W, since the peripheral region R1 is partitioned from the other region R2 by the partition member 3, the inflow of the scum Sc from the inflow port 3a into the peripheral region R1 is promoted and the scum Sc floating on the water surface WL is promoted. Can efficiently flow into the peripheral region R1. Furthermore, the peripheral region R1 is partitioned from the other region R2 by the partition member 3, so that the flow of water from the inlet 3a to the suction port 5a is not hindered in the peripheral region R1, and flows into the peripheral region R1. The scum Sc that has flowed through the peripheral region R1 is smoothly sucked from the suction port 5a.

  Further, as shown in FIGS. 1 and 2, in the flow path S, the sucked scum Sc moves toward the scum pit 92 due to the flow of water discharged from the discharge port 7 a, and in the flow path forming member 5. It blows out from the downstream end 52 in the discharge direction. As described above, the scum Sc blown from the downstream end 52 of the flow path forming member 5 gathers in the vicinity of the blocking wall 93 and opens the gate 931 to collect the scum in the vicinity of the blocking wall 93. Sc is collected in the scum pit 92 together with dirty water. Here, the flow of water once generated in the flow path S by discharging water from the discharge port 7a is not easily attenuated because the flow path S is surrounded by the flow path forming member 5, and the scum Sc has a long distance. Can be transported. Accordingly, the number of discharge ports 7a and supply pipes 7a for supplying water to the discharge ports 7a can be reduced, and a simple structure can be adopted. Furthermore, the amount of water discharged from the discharge port 7a can also be suppressed.

  In addition, when the flow path forming member 5 is long, the discharge member 7 may be provided at an intermediate portion in the extending direction of the flow path forming member 5 as shown by a one-dot chain line in FIG. Furthermore, when the length of the flowing water portion 91 is long, a plurality of the flow path forming members 5 and the partition members 3 are juxtaposed in the width direction of the flowing water portion 91, and the flow path S of each flow path forming member 5 Although the discharge member 7 which discharges water may be provided in this, it is good also as an aspect which enables the transfer apparatus 1 to move to the width direction, as shown by the double arrow of FIG.

  Further, as shown by a two-dot chain line in FIG. 2, the flow path forming member 5 and the partition member 3 are inclined so as to approach the water surface WL toward the downstream side in the discharge direction (so that the downstream side in the discharge direction becomes higher). In a manner in which water is discharged from the discharge port 7 a into the flow path S along the inclined posture of the flow path forming member 5. If this aspect is adopted, the flow of water generated in the flow path S by discharging water from the discharge port 7a is less likely to be attenuated, and the scum Sc can be transported for a longer distance. In addition, since a relatively strong water flow is generated in the portion near the discharge port 7a in the flow path S, the scum Sc floating on the water surface WL even when the position of the inflow port 3a is slightly deeper than the water surface WL. Is less likely to flow in from the inlet 3a.

  Next, modified examples of the transfer device shown in FIGS. 1 to 3 will be described with reference to FIGS. In the modified example described below, differences from the embodiment shown in FIGS. 1 to 3 will be mainly described, and the component having the same name as the component in the embodiment shown in FIGS. The description will be given with the reference numerals used so far, and redundant description may be omitted. 4 to 10 show the state corresponding to FIG. 3, and in order to simplify the drawing, for the discharge member 7, only the discharge port 7 a is shown, and the partition member 3 and the flow path forming member 5 are shown. The cross-sectional shape is typically shown.

  Fig.4 (a) is a figure which shows the transfer apparatus of a 1st modification. In this modification, the upper end portion 51 of the flow path forming member 5 is lower than the inflow port 3a of the partition member 3, that is, the upper end portion 51 of the flow path forming member 5 is the inflow port 3a of the partition member 3. The flow path forming member 5 and the partition member 3 are disposed so as to be deeper than the water surface WL. Thereby, the radial distance Di between the partition member 3 and the flow path forming member 5 becomes narrower toward the suction port 5a, and the flow rate of the water flowing in the peripheral region R1 becomes faster toward the suction port 5a. As a result, the scum Sc can be sucked more reliably from the suction port 5a.

  Further, as indicated by the alternate long and short dash line, a pipe material having a small diameter is used for the flow path forming member 5 and the opening length L3 in the width direction of the inflow port 3a formed by notching the upper side portion is the width of the suction port 5a. It is good also as an aspect shorter than the opening length L2 of a direction. By doing so, the flow rate of water flowing into the inflow port 3a is increased, and the scum Sc can be more smoothly flowed in from the inflow port 3a. In addition, since the partition member 3 shown by the alternate long and short dash line in FIG. 4A matches the center in the radial direction with the center in the radial direction of the flow path forming member 5, the partition member 3 and the flow path forming member 5. The radial distance Di is substantially the same at any location. However, similarly to the partition member 3 indicated by the solid line, the position of the flow path forming member 5 may be lowered so that the interval Di becomes narrower toward the suction port 5a.

  FIG.4 (b) is a figure which shows the transfer apparatus of a 2nd modification. In this modification, the flow path forming member 5 and the partition member 3 are disposed so that the upper end portion 51 of the flow path forming member 5 is higher than the inlet 3 a of the partition member 3. Thereby, the upper side part S1 in the flow path S is located above the inflow port 3a, and the radial distance Di between the partition member 3 and the flow path forming member 5 becomes wider toward the suction port 5a. In the second modification, the peripheral region R1 can be secured widely.

  Further, as shown by a one-dot chain line, the partition member 3 is formed using a pipe material having a small diameter, and the center in the radial direction is made to coincide with the center in the radial direction of the flow path forming member 5. It is good also as an aspect with which the space | interval Di of radial direction with the flow-path formation member 5 becomes the same in any location. The flow path forming member 5 may be arranged so that the upper end portion 51 is located on the water surface WL. However, the width of the water surface WL in the flow path forming member 5 is determined by the portion protruding on the water surface WL. Since the flow of water in the direction is blocked, a mode in which the flow path forming member 5 is disposed at a position where the upper end portion 51 is submerged in water is preferable. Furthermore, if the depth of the upper end portion 51 in the flow path forming member 5 from the water surface WL is set to 20 mm or more, it is preferable that the scum Sc is not easily placed on the upper end portion 51.

  Fig.5 (a) is a figure which shows the transfer apparatus of a 3rd modification. The transfer device 1 of the third modification is different from the transfer device 1 shown in FIG. 3 in that both have a flat partition member 3 and a flow path forming member 5. Specifically, the partition member 3 is formed by cutting out an upper end portion of a pipe having a height dimension of about ½ of the width dimension W1. The flow path forming member 5 is formed by cutting out the lower end portion of a pipe having a height dimension of about ½ of the width dimension W2. That is, the partition member 3 and the flow path forming member 5 in the present modification have a flat shape in which the dimension in the width direction orthogonal to the discharge direction in the horizontal plane is longer than the dimension in the height direction. Thus, if the flat partition member 3 is employed, the inflow port 3a can be easily widened in the width direction. If the inflow port 3a is widened in the width direction, the scum Sc floating in a wider area of the water surface WL can be caused to flow into the peripheral region R1. Further, by adopting the partition member 3 and the flow path forming member 5 that are both flat, the flow of the sewage W in the flowing water portion 91 (see FIG. 1) is less likely to be blocked, and the resistance to the flow of the sewage W is reduced. Is also possible.

  Note that, as indicated by the alternate long and short dash line, the position of the flow path forming member 5 may be lowered so that the upper end portion 51 of the flow path forming member 5 is lower than the inlet 3 a of the partition member 3. Moreover, it may replace with the flat partition member 3 and may use the partition member 3 shown in FIG. 3 mentioned above as shown with a dashed-two dotted line.

  FIG.5 (b) is a figure which shows the transfer apparatus of the 4th modification. The transfer device 1 of this modification is such that the upper end portion 51 of the flow path forming member 5 is higher than the inflow port 3a of the partition member 3 in the transfer device 1 of the third modification shown in FIG. The flow path forming member 5 and the partition member 3 are disposed. Thereby, the upper side part S1 in the flow path S is located above the inflow port 3a. Instead of the flat channel forming member 5, the channel forming member 5 shown in FIG. 3 described above may be used as indicated by a one-dot chain line.

  Fig.6 (a) is a figure which shows the transfer apparatus of the 5th modification. The transfer device 1 of this modification is different from the transfer device 1 shown in FIG. 3 in the shape of the partition member 3. As shown in FIG. 6A, the partition member 3 has a pair of vertically standing wall portions 32 and a bottom portion 33 that connects the lower end portions of the pair of wall portions 32 in the horizontal direction. Is a U-shaped cross-section opened. Here, as in the embodiment shown in FIG. 3 and the modification shown in FIGS. 4 and 5, if the inner peripheral surface of the partition member 3 is an arcuate shape, the partition member 3, the flow path forming member 5, When one of the partition member 3 and the flow path forming member 5 is moved in the vertical direction, depending on the magnitude relationship between the two and the opening length L3 of the inlet 3a in the partition member 3 (see FIG. 4A), The member 3 and the flow path forming member 5 may interfere with each other. According to this modification, since the vertically standing wall portion 32 is located on the side of the flow path forming member 5, as shown by the double arrows in the figure, the partition member 3 and the flow path forming member 5 When one of them is moved in the vertical direction, the partition member 3 and the flow path forming member 5 are less likely to interfere with each other. Thereby, the freedom degree at the time of moving one of the partition member 3 and the flow-path formation member 5 to a perpendicular direction improves. In addition, the partition member 3 can be easily manufactured.

  The partition member 3 and the flow path forming member 5 may be arranged so that the upper end portion 51 of the flow path forming member 5 is at the same height as the inflow port 3a of the partition member 3, but as indicated by the alternate long and short dash line The upper end portion 51 of the flow path forming member 5 may be set at a position lower than the inflow port 3 a of the partition member 3. As indicated by a two-dot chain line, the partition member 3 may be formed by curving the upper end side portion 321 of the wall portion 32 so as to spread outward in the width direction, or the wall portion 32 and the bottom portion 33. An arcuate corner 34 may be provided at the connecting portion.

  FIG.6 (b) is a figure which shows the transfer apparatus of a 6th modification. The transfer device 1 of this modification is such that the inflow port 3a of the partition member 3 is lower than the upper end portion 51 of the flow path forming member 5 in the transfer device 1 of the fifth modification shown in FIG. The flow path forming member 5 and the partition member 3 are disposed. In addition, as shown with a dashed-dotted line, you may form the bottom part 33 of the partition member 3 in the circular arc shape which protrudes below.

  Fig.7 (a) is a figure which shows the transfer apparatus of the 7th modification. In this modification, the shape of the partition member 3 is different from the transfer device 1 shown in FIG. As shown in FIG. 7A, the partition member 3 of the present modification has a second curved portion 35 that is curved to expand outward in the width direction at the upper end portion. Thereby, the inflow port 3a of the partition member 3 spreads, and the scum Sc floating in a wider area of the water surface WL can be caused to flow into the peripheral region R1 from the inflow port 3a. Further, as indicated by the alternate long and short dash line, the flow path forming member 5 may be disposed at a position where the upper end portion 51 of the flow path forming member 5 is lower than the inlet 3 a of the partition member 3.

  FIG.7 (b) is a figure which shows the transfer apparatus of the 8th modification. The transfer device 1 of this modification is such that the upper end portion 51 of the flow path forming member 5 is higher than the inlet 3a of the partition member 3 in the transfer device 1 of the seventh modification shown in FIG. The partition member 3 and the flow path forming member 5 are disposed. Moreover, in this modification, the part with the smallest radial distance Di between the partition member 3 and the flow path forming member 5 is set to be substantially the same as the opening length L2 in the width direction of the suction port 5a. In addition, as shown with a dashed-dotted line, the partition member 3 with a small diameter is employ | adopted, and the space | interval Di of the radial direction of the 2nd curved part 35 and the flow-path formation member 5 is based on the opening length L2 of the width direction of the suction inlet 5a. May be shortened to increase the flow rate of water passing through the interval Di.

  FIG. 8 is a diagram illustrating a transfer device according to a ninth modification. In this modified example, the depth Dp1 and the opening length L3 from the water surface WL at the inlet 3a in a state where the upper end portion 51 of the flow path forming member 5 and the depth of the discharge port 7a from the water surface WL are constant, and The depth Dp3 and the opening length L2 from the water surface WL at the suction port 5a can be adjusted.

  8A, the partition member 3 has a pair of half-arc-shaped partition member structural bodies 30 as shown by being surrounded by a two-dot chain line, and FIG. 8A and FIG. As shown in b), the partition member 3 is configured by overlapping a part of the pair of partition member constituting bodies 30 with each other. In FIG. 8A and FIG. 8B, the portion where the pair of partition member constituting bodies 30 overlap is indicated by the symbol β. The pair of partition member constituting bodies 30 can rotate about the center O in the radial direction as the rotation center, and can change the size of the overlapping portion β.

  When the overlapping portion β is reduced as shown in FIG. 8B from the state of the partition member 3 shown in FIG. 8A, the depth Dp1 of the inflow port 3a from the water surface WL becomes shallow, and the inflow port 3a. The opening length L3 is narrowed. Although illustration is omitted, on the contrary, when the overlapping portion β is increased, the depth Dp1 of the inflow port 3a from the water surface WL is increased, and the opening length L3 of the inflow port 3a is increased. Thus, the depth Dp1 and the opening length L3 of the inflow port 3a from the water surface WL can be adjusted by changing the size of the portion β where the pair of partition member structures 30 overlap. In addition, in FIG. 8, although the aspect which adjusts the depth Dp1 from the water surface WL of the inflow port 3a when the height of the water surface WL was constant was described as an example, the variation in the height of the water surface WL was described. It is good also as an aspect adjusted by making it follow and the depth Dp1 from the water surface WL of the inflow port 3a becomes fixed.

  Further, as shown in FIGS. 8A and 8B, the flow path forming member 5 includes a flow path forming member main body 50 having a circular arc shape in which approximately 1/3 below the cylindrical body is cut off, The flow path forming member main body 50 includes a pair of slide pieces 53 provided at both ends of the notched portion. Each of the pair of slide pieces 53 has a 1/5 arc shape, and a lower end portion projects downward from the flow path forming member main body 50, and a suction port 5a is formed between these lower end portions. Each of the pair of slide pieces 53 slides along the inner peripheral surface 50a of the flow path forming member main body 50, thereby adjusting the depth Dp3 and the opening length L2 of the suction port 5a from the water surface WL. Can do.

  Specifically, from the state of the flow path forming member 5 shown in FIG. 8A, each of the pair of slide pieces 53 is changed into a flow path as shown by a dotted arcuate arrow in FIG. 8B. When sliding inside the forming member main body 50 (upward), the depth Dp3 of the suction port 5a from the water surface WL becomes shallow, and the opening length L2 of the suction port 5a becomes wide. Although not shown, conversely, when each of the pair of slide pieces 53 is slid to the outside (downward) of the flow path forming member main body 50, the depth Dp3 of the suction port 5a from the water surface WL increases, The opening length L2 of the mouth 5a is narrowed.

  The configuration of the partition member 3 in the modification shown in FIG. 8 may be applied to the flow path forming member 5, or the configuration of the flow path forming member 5 may be applied to the partition member 3. Further, by dividing the pair of partition member constituting bodies 30 and the slide piece 53 into a plurality of parts in the discharge direction and adjusting each of them, for example, the depth Dp1 of the inflow port 3a from the water surface WL and the opening of the suction port 5a The length L2 or the like can be made different between the upstream side in the discharge direction and the downstream side in the discharge direction.

  FIG. 9 is a view showing a transfer device of a tenth modification. In the transfer device 1 of this modification, the flow path forming member 5 is supported by the partition member 3 in a so-called cantilever state in which the partition member 3 is connected to one end in the width direction (the left end portion in the figure). It is. Conceptually, each of the flow path forming member 5 and the partition member 3 has a common portion 4 indicated by a dotted line that is partially shared with each other, as surrounded by a two-dot chain square. Thereby, it becomes easy to ensure the radial distance Di between the partition member 3 and the flow path forming member 5. In the present modification, the inner peripheral surface 4 a is a continuous curved surface from the partition member 3 to the flow path forming member 5. Thereby, the flow of water from the inlet 3a of the partition member 3 toward the suction port 5a becomes a smooth flow along the inner peripheral surface 4a, and the scum Sc is smoothly sucked from the suction port 5a of the flow path forming member 5. Can do. In addition, the height (depth from the water surface WL) of the upper end portion 51 of the flow path forming member 5 is set to the height (from the water surface WL) of the other end (right end portion in the drawing) of the partition member 3 in the width direction. (Depth), as shown in FIG. 9, if the height of the upper end portion 51 of the flow path forming member 5 and the height of the other end of the partition member 3 in the width direction are the same, The scum Sc is preferable because it easily flows into the inflow port 3a from both sides in the width direction.

  FIG. 10 is a diagram illustrating a transfer device according to an eleventh modification. In this modification, the partition member 3 is omitted, and the flow path forming member 5 is arranged in a posture in which the suction port 5a faces upward. In the present modification, when water is discharged from the discharge port 7a into the flow path S of the flow path forming member 5, it is drawn into the flow of the discharged water and flows from the suction port 5a as shown in FIG. A flow of water in the direction of being sucked into the path S is generated. Accordingly, as conceptually showing the flow of the scum Sc in FIG. 10, the scum Sc floating on the water surface WL of the water flow portion 91 gathers toward the suction port 5a and is sucked into the flow path S from the suction port 5a. It is. The scum Sc sucked into the flow path S moves in the transfer direction by the flow of water discharged from the discharge port 7a.

  In addition, as shown by the circular arc-shaped double arrow, the flow path forming member 5 is rotated with the center O in the radial direction as the rotation center, and the direction in which the suction port 5a is opened, which is indicated by the straight arrow, is the angle α. It is good also as an aspect which can be changed in the range. As the flow path forming member 5, a flat flow path forming member 5 in the transfer device 1 of the third modified example in FIG. In the embodiment shown in FIG. 3 and the modified example having the partition member 3 shown in FIG. 4 and the like, a mode in which the partition member 3 is rotated about the center in the radial direction may be adopted.

  Next, a description will be given of a second embodiment of the transfer device of the present invention in which the installation equipment is different. Also in the second embodiment described below, the components having the same names as the component names in the embodiment shown in FIGS. May be omitted.

  FIG. 11 is a schematic configuration diagram of the overturning structure provided with the transfer device according to the second embodiment of the present invention. The overhang structure is a structure in which when the sewer pipe crosses rivers, railways, etc., the overhang pipe is installed at a position lower than these rivers, and the sewage flows by the difference in water level between the upstream and downstream pipes. Say.

  In the overhang structure 8, the sewage DR flows from the left side to the right side of the river Ri in FIG. 11, and the direction from the left to the right is the direction in which the sewage DR flows as shown by the white arrow in the figure. . As shown in FIG. 11, the overhang structure 8 includes an upstream pipe 81, an upstream manhole 82, an overhang pipe 83, a downstream manhole 84, and a downstream in the order from the upstream side to the downstream side of the sewage DR flow. A side conduit 85 is provided. The upstream pipe 81 is connected to the upstream manhole 82, and the overpass pipe 83 is connected to the upstream manhole 82 and the downstream manhole 84 at a position lower than the river Ri. The downstream pipe 85 is connected to the downstream manhole 84 at a position lower than the position where the upstream pipe 81 is connected to the upstream manhole 82. Sediment reservoirs 821 and 841 are formed at the bottom of the upstream manhole 82 and the bottom of the downstream manhole 84, respectively.

  The sewage DR that has flowed through the upstream side pipe 81 flows from the upstream manhole 82 through the overlying pipe 83 by a so-called reverse siphon action caused by a water level difference between the upstream side pipe 81 and the downstream side pipe 85. Furthermore, the downstream side manhole 84 flows through the downstream side pipe 85.

  Here, the upstream side pipe line 81 is provided with the transfer device 1 having the same configuration as the transfer device 1 shown in FIGS. In the transfer device 1, the downstream end 52 of the flow path forming member 5 is located in the vicinity of a region where the upstream pipe line 81 is connected to the upstream manhole 82. As in the transfer device 1 shown in FIGS. 1 to 3 described above, when water is discharged from the discharge port 7a, the scum Sc floating on the water surface WL of the sewage DR is sucked into the flow path forming member 5 and then upstream. By being transferred toward the side manhole 82 and blown out from the downstream end 52 of the flow path forming member 5, the water is collected on the water surface WL of the sewage DR in the upstream manhole 82.

  The scum Sc collected on the water surface WL of the sewage DR in the upstream manhole 82 is removed by opening the iron lid of the upstream manhole 82, and a part of the scum Sc is drawn into the flow of the sewage DR and the overpass pipe 83. In addition, the sand etc. which settled in the earth and sand reservoir 821 also flows into the overburden pipe 83 by the flow of the sewage DR. The overhead pipe 83 is provided with a transfer device 1 having the same configuration as the transfer device 1 shown in FIGS. 1 to 3 and a sediment transfer device 2 for transferring sediment such as sedimented sand.

  FIG. 12 is a cross-sectional view taken along the line CC of the overhang pipe shown in FIG. In FIG. 12, the both side regions in the width direction and the intermediate region in the vertical direction in the overturn pipe 83 are omitted.

  As shown in FIG. 12, the inside of the overhang pipe 83 is filled with sewage DR, and the water surface WL of the sewage DR is in contact with the ceiling surface 831 of the overhang pipe 83. In the transfer device 1, the depth Dp1 from the water surface WL, that is, the ceiling surface 831 in the inlet 3a of the partition member 3 and the upper end portion 51 of the flow path forming member 5 is set to 20 mm or more. When the depth Dp1 from the water surface WL is less than 20 mm, it is between the ceiling surface 831 of the overhanging pipe 83 and the inlet 3a of the partition member 3, or the ceiling surface 831 of the overhanging pipe 83 and the flow path forming member 5 It is not preferable because the scum Sc is easily caught between the upper end portion 51 and the scum Sc.

  When water is discharged from the discharge port 7a of the discharge member 7 into the flow path S of the flow path forming member 5, a flow of water in the direction of being sucked into the flow path S from the suction port 5a is generated, and from the inflow port 3a to the periphery A flow of water flowing into the region R1 is generated, and a water flow toward the suction port 5a is generated in the peripheral region R1. As a result, on the water surface WL (in the vicinity of the ceiling surface 831), a flow in the direction of collecting at the inflow port 3a of the partition member 3 is generated, and the scum Sc floating in the vicinity of the ceiling surface 831 is collected. It flows into region R1. The scum Sc flowing into the peripheral region R1 is sucked into the flow path S from the suction port 5a, and the sucked scum Sc is transferred to the downstream manhole 84. Thereby, the problem that the scum Sc adheres to the ceiling surface 831 of the overhanging pipe 83 and remains in the overhanging pipe 83 can be solved.

  A sediment transfer device 2 that transfers sediment is provided on the bottom surface 832 on the bottom side of the overhang pipe 83. Further, the bottom of the overhang pipe 83 is modified, and a pair of inclined surfaces 833 inclined downward toward the sediment transfer device 2 are provided by a portion modified by concrete shown by cross hatching. The sediment transfer device 2 includes a trough 21, a bottom-side flow path forming member 25, and a bottom-side discharge member 27. The trough 21 forms a groove M extending in the direction from the upstream manhole 82 toward the downstream manhole 84 (see FIG. 11) on the bottom side of the overhang pipe 83. The portion opened upward of the trough 21 becomes the opening 21a of the groove M, and the lower end of the inclined surface 833 is connected to the opening 21a of the groove M. The bottom-side flow path forming member 25 extends in the same direction as the trough 21, and its entire length is formed to be approximately the same length as the trough 21. The bottom-side flow path forming member 25 forms the bottom-side flow path S2, and partitions the bottom-side flow path S2 and the groove M from each other. Further, the bottom-side flow path forming member 25 has an in-groove suction port 25a connected to the bottom-side flow path S2 and positioned in the groove M. The bottom discharge member 27 is provided with a bottom discharge port 27a, and water is discharged from the bottom discharge port 27a into the bottom flow path S2.

  Sediment such as sand contained in the sewage DR that has flowed into the overlying pipe 83 sinks in the course of the sewage DR flowing downstream, and flows down toward the trough 21 along the inclined surface 833. The sediment flowing down from the inclined surface 833 enters the groove M from the opening 21a of the trough 21. Also, sand or the like accumulated in the sediment reservoir 821 of the upstream manhole 82 shown in FIG.

  When water is discharged from the bottom discharge port 27a into the bottom flow path S2, the sediment that is drawn into the flow of the discharged water and accumulates at the bottom of the groove M is indicated by the curved arrow shown in FIG. As described above, the air is sucked into the bottom channel S2 from the in-groove suction port 25a. Further, in the bottom channel S2 of the bottom channel forming member 25, the sucked sediment is discharged downstream in the discharge direction (downstream manhole 84 side) by the flow of water discharged from the bottom discharge port 27a. Move towards. Accordingly, sediment such as sand can be transferred to the earth and sand reservoir 841 and the like of the downstream manhole 84 without remaining in the overpass pipe 83.

  The present invention is not limited to the above-described embodiment, and various modifications can be made within the scope described in the claims.

  In addition, even if it is a structural requirement contained only in each description of each embodiment and each modification demonstrated above, you may apply the structural requirement to another embodiment and another modification.
