Description

  The present invention relates to a siphon drainage system, and more particularly to a siphon drainage system including a storage tank divided into a plurality of parts.

  In recent years, siphon drainage systems have been proposed in place of conventional gradient drainage systems. As described in Patent Document 1, the siphon drainage system is composed of a watering device and a siphon drainage pipe. The siphon drainage system generates a siphon force (negative pressure) generated in a dredging pipe that forms the hanging part of the siphon drainage pipe. It is a system that uses it to improve drainage efficiency from watering equipment.

Further, in the siphon drainage system, a siphon drainage system is also proposed in which a storage tank for temporarily storing drainage from a watering device is disposed in the drainage system.

  In the siphon drainage system, there is a time lag between the start of drainage and the siphon start-up. It can be prevented by drainage. That is, until the storage tank is full, drainage from the watering device can be performed by storing the wastewater from the watering device in the storage tank. In order to exhibit the function of such a storage tank, it is necessary to ventilate the air in the storage tank. This is because if the ventilation in the storage tank is not performed, the drainage cannot flow into the storage tank from the watering device, and the drainage overflows from the watering device. Therefore, installing a vent pipe in the storage tank is performed.

  By the way, when it is set as the structure which provides a storage tank and accumulates waste_water | drain in a storage tank temporarily, as shown in FIG. 7, the storage tank Y may be divided into a some division corresponding to an inflow and an outflow path | route. . In this case, each compartment part is normally connected upward, and when the water stored in one compartment part is full, the other compartment part overflows and the volume of the storage tank can be used effectively. ing. As described above, when a plurality of sections are configured, drainage from the watering device corresponding to each section is performed for each section until each section is full of water. Therefore, the drainage is not dispersed to multiple siphon drainage pipes in the storage tank until the compartments are full, and the siphon is not easily dispersed in each compartment. It has the effect of accelerating startup. That is, there is an advantage that siphon drainage can be started even with a small amount of drainage.

  When the above-described vent pipe A is installed in the storage tank Y having such a configuration, as shown in FIG. 7, when connected to a location corresponding to one partition portion, when the partition portion becomes full, the opening of the vent tube A The part may be closed by drainage, preventing ventilation. In other words, it is possible that the vent pipe does not function even if the other compartment portion is not full, but only one compartment portion is full.

  This invention is made | formed in view of the said fact, and it aims at providing the siphon drainage system which can ventilate appropriately in the storage tank divided into several parts.

  In the siphon drainage system according to claim 1 of the present invention, the drainage discharged from the watering device is stored, the storage space for storing the drainage is partitioned into a plurality of individual storage portions by a partition member, and the plurality of individual storage systems are stored. A storage tank in which a storage part is connected to each other, a siphon drain pipe that is connected to the storage tank and discharges the waste water stored in the storage tank, and is connected to the storage tank, and at least two of the plurality of individual storage parts And a vent pipe communicated with each other.

  In the siphon drainage system of the present invention, a storage tank is provided on the upstream side of the siphon drain pipe. In the storage tank, drainage from the watering device is stored. A storage space for storing drainage is formed inside the storage tank, and the storage space is partitioned into a plurality of individual storage units by a partition member.

  When the wastewater flows into the storage tank having the above-described configuration, first, the wastewater is stored in the individual storage unit into which the wastewater flows directly. When this individual storage part becomes full, drainage flows from this individual storage part into another individual storage part. At this time, the communication part with the ventilation pipe in the individual storage part that is full of water is closed by drainage. Even in such a case, in the present invention, the vent pipe is communicated with another individual reservoir, and the communication portion between the other individual reservoir and the vent pipe that is not full is not closed by drainage. Therefore, the storage tank can be properly ventilated.

  The siphon drainage system according to claim 2 is characterized in that the vent pipe communicates with each of the plurality of individual storage portions.

  Thus, siphon drainage can be performed while ventilating appropriately using the entire storage tank by communicating the ventilation pipe with all the individual storage units.

  The siphon drainage system according to claim 3 is characterized in that the vent pipe is connected to an upper portion of the storage tank.

  In this way, by connecting the vent pipe at the upper part of the storage tank, the communication between the vent pipe and the individual storage section can be appropriately performed with a simple configuration until the individual storage section is full of water.

  The siphon drainage system according to claim 4, wherein the vent pipe includes an individual vent connected to the individual reservoir and a merged trachea to which the individual vents are joined. Features.

  According to the said structure, while communicating with an individual storage part with a some separate ventilation part, the open | release to the air | atmosphere of this individual ventilation part can be performed with one combined circulation pipe.

  The siphon drainage system according to claim 5, wherein the vent pipe has an upper vent path formed in a convex shape at the upper part of the storage section across the individual storage sections, and a communication pipe communicating with the vent path, It is comprised by these.

  According to the said structure, ventilation | gas_flowing for every separate storage part can be performed with a simple structure.

  In the present invention, since the ventilation pipe communicates with each individual storage portion as described above, the storage tank can be appropriately ventilated.

  Embodiments according to the present invention will be described below with reference to the drawings.

  First, the overall configuration of the siphon drainage system according to the present embodiment will be described. FIG. 1 is a schematic view showing the overall configuration of the siphon drainage system according to the present embodiment.

  A siphon drainage system 10 according to the present embodiment is a drainage system that efficiently drains drainage from a watering device using siphon force.

  The siphon drainage system 10 of this embodiment is mainly used in an apartment house composed of a plurality of floors. As shown in FIG. 1, the siphon drainage system 10 includes a drainage stack 12 that allows drainage to flow downward. The drainage stack 12 extends in the vertical direction (longitudinal direction) of the apartment house, and penetrates the floor slab 14 on each floor of the apartment house.

  A plurality of watering devices 16 are provided in each door of each floor of the apartment house, and one end of a drain introduction pipe 18 through which drainage discharged from the watering device 16 flows is connected to each watering device 16. ing. The other end of the drainage introduction pipe 18 is connected to the storage tank 50. The drainage introduction pipe 18 is disposed with a gradient so that the storage tank 50 side is lowered.

  The storage tank 50 is for temporarily storing drainage from the watering device 16. As shown in FIG. 2A, a storage space 52 is formed inside the storage tank 50. The storage space 52 is partitioned into three individual storage portions 52A, 52B, and 52C by a partition member 54. As shown in FIG. 2B, the partition member 54 is arranged up to a position slightly lower than the uppermost portion of the storage space 52 so that the individual storage portions 52A, 52B, and 52C communicate with each other above. Yes. The plurality of drainage introduction pipes 18 from the watering device 16 described above are respectively connected to the individual reservoirs 52A, 52B, 52C.

  Siphon drain pipes 22A, 22B, and 22C are connected to the individual storage sections 52A, 52B, and 52C of the storage tank 50, respectively (these are collectively referred to as “siphon drain pipe 22”). As shown in FIG. 1, the siphon drain pipe 22 includes a horizontal pulling pipe 24 disposed along the floor slab 14, and a soot pipe 26 communicating with the horizontal pulling pipe 24. The horizontal pulling pipe 24 communicates with the storage tank 50 and is disposed on the floor slab 14 with no gradient in the horizontal direction. The soot pipe 26 communicating with the horizontal pulling pipe 24 is disposed in the vertical direction (vertical direction) along the drainage stack 12. The soot pipe 26 is connected to the drainage stack 12 through a junction joint 40. The junction joint 40 joins the drainage from the soot pipe 26 to the drainage stack 12.

  The horizontal pulling pipe 24 and the vertical pipe 26 are constituted by a single drainage pipe, and the drainage is led to the drainage stack 12 without joining the other drainage pipes up to the junction 40 in the middle. . Further, the inner diameter of the horizontal pulling pipe 24 and the dredging pipe 26 is set so that the drainage flows in a full flow. A siphon force in the direction of drainage is applied to the drainage in the horizontal pipe 24 by the energy of the siphon head Hs.

  A vent pipe 30 is further connected to the storage tank 50. As shown in FIG. 3, the vent pipe 30 is composed of the individual vent portions 30A, 30B, 30C and the individual vent portions 30A, 30B, 30C respectively connected to the individual reservoir portions 52A, 52B, 52C. The unit is configured to include one common circulation tube 30D. The individual ventilation portions 30 </ b> A, 30 </ b> B, 30 </ b> C have communication ports at positions corresponding to the individual storage portions 52 </ b> A, 52 </ b> B, 52 </ b> C above the storage tank 50, and are piped on the upper side of the storage tank 50. One end side of the combined circulation pipe 30D is connected to the drainage stack 12 via the junction joint 40, and the other end side is connected to the individual ventilation portions 30A, 30B, and 30C.

  Next, drainage in the siphon drainage system 10 of this embodiment will be described.

  Drainage from the watering device 16 flows into the storage tank 50 through the drainage introduction pipe 18. The drainage from the drainage introduction pipe 18 first flows into the storage space 52 (individual storage units 52A to 52C) to which the drainage introduction pipe 18 is connected. Here, an example of drainage from the watering device 16 connected to the individual reservoir 52B will be described.

  The waste water that has flowed into the individual reservoir 52B is discharged from the siphon drain pipe 22B connected to the individual reservoir 52B. When the amount of inflow from the drainage introduction pipe 18 exceeds the amount of drainage in the siphon drainage pipe 22B, the stored water level of the individual storage section 52B increases. As shown in FIG. 4A, when the stored water level exceeds the upper end of the partition member 54, the waste water overflows from the individual storage part 52B and flows into the individual storage parts 52A and 52C. At this time, the individual ventilation part 30B connected to the individual storage part 52B is closed by the stored drainage, and ventilation in the individual ventilation part 30B becomes impossible.

  On the other hand, for the individual reservoirs 52A and 52C, the drained water that flows in is discharged from the siphon drain pipes 22A and 22C. Thereby, compared with the case where it discharged | emitted only by the siphon drain pipe 22B, the whole waste water treatment amount in the storage tank 50 increases, and it can drain appropriately. At this time, the stored water level of the waste water in the individual storage parts 52A and 52C is lower than that of the individual storage part 52B, and the individual ventilation parts 30A and 30C are not closed, so that ventilation can be performed appropriately.

  In addition, when the waste_water | drain from the watering device 16 flows into both the separate storage parts 52A and 52B, as shown to FIG. 4 (B), it assumes that the separate storage parts 52A and 52B become full. Is done. Even in this case, since the individual ventilation part 30C corresponding to the individual storage part 52C that is not full of water is not closed, as shown in FIG. 4C, until all of the individual storage parts 52A to 52C become full. Can ventilate properly.

  As described above, according to the present embodiment, since the vent pipe 30 (individual vents 30A to 30C) is connected to each of the individual reservoirs 52A to 52C, the capacity of the reservoir 50 is effectively used. It is possible to ventilate appropriately.

  In addition, in this embodiment, although the structure which connected each ventilation part 30A-30C of the ventilation pipe 30 to each of the individual storage parts 52A-52C was demonstrated, the ventilation pipe of this invention is the individual storage part 52A-52C. It only needs to be communicated with each other, and other configurations can be used.

  For example, as shown in FIGS. 5 and 6, a convex ventilation part 31 is formed on the upper surface of the storage tank 50 so as to straddle the individual storage parts 52 </ b> A to 52 </ b> C, and the ventilation path 31 </ b> A in the ventilation part 31 is individually set. It is good also as a structure connected with storage part 52A-52C. In this case, even when the stored water level of the waste water in the individual storage portions 52A to 52C exceeds the partition member 54, the air passage 31A is not closed, and air can be appropriately secured.

  Moreover, although the siphon drainage system 10 which concerns on this embodiment demonstrated as what discharges | emits the waste_water | drain from a watering apparatus efficiently, what is used in order to discharge | emit the wastewater from those other than the watering apparatus 16, such as rain water, efficiently. It can also be applied to siphon drainage systems used for cooling water in factories.
