Description

本発明は、厨芥粉砕装置から押し出される厨芥排水を排水横枝管を経て立て管内に効果的に搬送することのできる厨芥排水の搬送システムに関する。   The present invention relates to a soot drainage transport system capable of effectively transporting soot drained from a soot crusher into a standing pipe through a drainage horizontal branch pipe.

台所に設置される厨芥粉砕装置の排出口から押し出される厨芥排水を該排出口に連通される排水横枝管を経て立て管内に搬送するものとなされた厨芥排水の搬送システムは存在している（特許文献１参照）。   There is a wastewater drainage transport system that transports wastewater drained from a discharge port of a waste crusher installed in a kitchen into a vertical pipe through a drainage branch pipe communicated with the discharge port ( Patent Document 1).

この種の搬送システムでは、一般に、排水横枝管は管径を例えば４０Ａ〜５０Ａ程度となされ出口側へ漸次降下するように傾斜されており、厨芥粉砕装置の排出口から押し出された厨芥排水は該排水横枝管内を管長さ方向上の高低差によるポテンシャルエネルギーにて出口側へ流下するのであり、このさい排水横枝管内の厨芥排水にはこれの流下を促進するためのサイホン作用は付与されない。   In this type of transport system, generally, the drainage side branch pipe has a pipe diameter of, for example, about 40A to 50A and is inclined so as to gradually descend toward the outlet side. The drainage side branch pipe flows down to the outlet side with potential energy due to the height difference in the length direction of the pipe, and the dredging drainage in the drainage side branch pipe is not given siphon action for promoting the flow of the drainage side branch pipe. .

また水回り器具（洗面器など）の排出口から排出される排水を排水横枝管を経て立て管内に搬送するさいに、排水横枝管内にサイホン水頭ポテンシャルエネルギーによりサイホン作用を付与し、排水横枝管内の排水の流下を促進するものとなされたサイホン排水システムは存在している（特許文献３）。

上記した従来の厨芥排水の搬送システムでは次のような問題点がある。
即ち、
（１）比重の重い固形物の含まれる厨芥排水を搬送するためには、排水横枝管の配管勾配を１／５０以上以上にする必要があって、高さ方向の配管施工スペースが大きくなり、この結果、床下の不要なスペースが増えることになって不経済である。
（２）厨芥排水には、比重の重い固形物や比重の軽い固形物などが種々の割合で混合した多種多様のものが存在するが、このような厨芥排水において、比重の重い生ゴミなどの固形物は排水横枝管の管底を流れるため、多量の追い水を流しても影響を受け難く、配管途中で堆積し、配管閉塞を生じさせる危険性がある。
（３）従来のサイホン排水システムは全て同径であるため、有効なサイホン水頭ポテンシャルエネルギーを得るには、引落とし立て管の配管長さが１０００ｍｍ以上必要であり（特許文献４参照）、配管施工スペースが大きくなり、不経済である。 The above-described conventional wastewater transfer system has the following problems.
That is,
(1) In order to transport dredged wastewater containing heavy solid matter, it is necessary to make the piping gradient of the drainage side branch pipe 1/50 or more, and the piping construction space in the height direction becomes large. As a result, unnecessary space under the floor increases, which is uneconomical.
(2) There is a wide variety of dredged wastewater that is mixed with solids with a high specific gravity or light solids at various ratios. Since the solid material flows through the bottom of the drainage horizontal branch pipe, it is difficult to be affected even if a large amount of additional water is flowed, and there is a risk of accumulating in the middle of the pipe and causing the pipe to be blocked.
(3) Since all the conventional siphon drainage systems have the same diameter, in order to obtain effective siphon head potential energy, the pipe length of the draw-up standpipe is required to be 1000 mm or more (see Patent Document 4). Space is large and uneconomical.

本発明は、上記した（１）〜（３）に記載した問題点を解決することのできる厨芥排水の搬送システムを提供することを目的とする。   An object of this invention is to provide the conveyance system of the wastewater which can solve the problem described in said (1)-(3).

上記目的を達成するため、本願の第１発明に係る厨芥排水の搬送システムは、請求項１に記載したように、台所に設置され排出口から厨芥排水を押し出す厨芥粉砕装置の前記排出口に連通される排水横枝管の管径が３０Ａ以下となされたことを特徴とするものである。   In order to achieve the above object, a wastewater transfer system according to the first invention of the present application is communicated with the discharge port of a waste crusher that is installed in a kitchen and pushes wastewater drainage from the discharge port. The diameter of the drainage horizontal branch pipe is 30A or less.

この発明は次のように具体化するのがよい。
即ち、請求項２に記載したように、排水横枝管の末端を引落とし立て管となして階下へ落とし、該引落とし立て管の高さ途中位置よりも下方部位をその上流側よりも小径となされた絞り管部となし、該絞り管部をその絞り開始点から２００ｍｍ以上低い位置で立て管に接続した構成とする。 The present invention is preferably embodied as follows.
That is, as described in claim 2, the end of the drainage horizontal branch pipe serves as a draw-down stand pipe and is dropped downstairs, and the lower portion of the drop stand pipe is located at a lower diameter than its upstream side. The throttle tube portion is formed, and the throttle tube portion is connected to the standing tube at a position 200 mm or more lower than the throttle start point.

また請求項３に記載したように、厨芥粉砕装置から排水横枝管に至る排水系に排水が流れることを検知して厨芥粉砕装置を自動的に起動させるものとした制御回路を備えた構成とする。   According to a third aspect of the present invention, there is provided a configuration including a control circuit that automatically detects the flow of waste water to the drainage system from the waste crusher to the drainage branch pipe and automatically activates the waste crusher. To do.

さらには請求項４に記載したように、厨芥粉砕装置から排水横枝管に至る途中に形成されたトラップの内方に厨芥粉砕装置の作動に関連して水を供給するものとした水供給手段を設けた構成とする。   Furthermore, as described in claim 4, the water supply means for supplying water in relation to the operation of the slag crusher to the inside of the trap formed in the middle from the slag crusher to the drainage lateral branch pipe It is set as the structure which provided.

次に本願の第２発明に係る厨芥排水の搬送システムは、請求項５に記載したように、排水横枝管の末端を引落とし立て管となして階下へ落とし、該引落とし立て管の高さ途中位置よりも下方の部位を、その上流側よりも小径となされた絞り管部となし、該絞り管部内の排水流下がサイホン作用の生成を促進させる構成とする。   Next, as shown in claim 5, the dredging drainage conveyance system according to the second invention of the present application drops the end of the drainage horizontal branch pipe into the downdraft pipe and drops it downstairs. The part below the midway position is formed as a throttle pipe part having a smaller diameter than the upstream side, and the drainage flow in the throttle pipe part promotes the generation of siphon action.

上記した本発明によれば、次のような効果が得られる。
（１）請求項１記載の発明によれば、厨芥粉砕装置が厨芥排水を例えば毎分凡そ８リットル程度の流量でその排出口から排水横枝管内に押し出すと、排水横枝管内の厨芥排水は排水横枝管内を空気及び排水の２相状態或いは満水状態となって流下するものとなり、一方、排水横枝管は端末を引落とし立て管となされた場合に、該端末にサイホン水頭のポテンシャルエネルギーにより生成されるサイホン作用が付与されるのであり、このさい厨芥粉砕装置の排水の押出力は排水横枝管の下流側へ向かうほど摩擦力などで減衰されると共にサイホン作用は排水横枝管の端末で発生されて上流側へ向かうほど減衰される傾向となり、したがって排水横枝管の上流端側では減衰の程度が比較的小さい押出力が排水搬送に効果的に寄与し、一方、排水横枝管の下流端側では減衰の程度が比較的小さいサイホン作用が排水搬送に効果的に寄与するものとなって、排水横枝管内の厨芥排水は排水横枝管の全長範囲で比較的大きな速度で流下するようになるのであり、この結果、排水流量が毎分凡そ８リットル程度である一般家庭の厨芥粉砕装置から排出される厨芥排水は、厨芥粉砕装置の排水押出力のみにより排水を搬送させるときの厨芥排水量や、サイホン作用のみにより排水を搬送させるときの厨芥排水量の流速及び流量よりも比較的大きな流速及び流量で排水横枝管内を下流側へ搬送されると共に、排水横枝管内の流速が大きくなる分、厨芥排水に含まれている重い厨芥などの排水横枝管内での堆積が生じ難くなり、該堆積による管内閉塞が効果的に抑制される。 According to the present invention described above, the following effects can be obtained.
(1) According to the first aspect of the present invention, when the slag pulverizer pushes the sewage drainage from its outlet into the drainage branch pipe at a flow rate of about 8 liters per minute, The drainage side branch pipe flows down in a two-phase or full state of air and drainage. On the other hand, when the drainage side branch pipe is pulled down as a standpipe, the potential energy of the siphon head is given to the terminal. The siphon action generated by this is added, and the pushing force of the drainage of this pulverizer is attenuated by the frictional force and so on toward the downstream side of the drainage side branch pipe, and the siphon action is Since it is generated at the terminal and tends to be attenuated toward the upstream side, the pushing force with a relatively small degree of attenuation effectively contributes to drainage conveyance on the upstream end side of the drainage lateral branch pipe, while The siphon action with a relatively small attenuation at the downstream end of the pipe effectively contributes to drainage transportation, and dredging drainage in the drainage side branch pipe is at a relatively high speed over the entire length of the drainage side branch pipe. As a result, when the wastewater discharged from a general household waste crusher with a drainage flow rate of about 8 liters per minute is transported only by the wastewater pushing force of the wastewater crusher It is transported downstream in the drainage branch pipe at a flow rate and flow rate that is relatively larger than the flow rate and flow rate of the soot drainage amount when the wastewater is transported only by siphon action, and the flow rate in the drainage side branch pipe is As the size increases, accumulation in the drainage horizontal branch pipe such as heavy soot contained in the drainage becomes difficult to occur, and blockage in the pipe due to the accumulation is effectively suppressed.

（２）請求項２記載の発明によれば、引落とし立て管の配管長さが短くても、絞り管部を有するために、サイホン作用が排水横枝管内の厨芥排水に効率よく付与され、しかも排水横枝管内の厨芥排水の流量の変動などに対して安定的に発生し、排水横枝管内の厨芥排水の流速を速くする効果があるのであり、絞り管部の管径をその上流側の管径の４／５程度以下に絞って絞り管部の長さを２００ｍｍ以上にすると、厨芥排水が排水横枝管内を毎分８リットル程度の流量で流下するときに、このような効果が有効に得られる。また絞り管部の長さを凡そ６００ｍｍ程度以上となした場合において、厨芥排水の流量が凡そ毎分８リットル程度であるときは排水横枝管内の流速が一般的なデータとして紹介されているところの管内に堆積することなく、安全な排水状態が得られるとされている０．６ｍ／ｓ以上となすことができ、排水横枝管内の厨芥が搬送され易くなる。なお、排水横枝管内の厨芥排水を該排水横枝管の絞り管部の存在しない同径管となした引落とし立て管を経て他所へ排出するときは、厨芥排水の流量変化や引落とし立て管の長さ変化に起因してサイホン効果が途切れ易くなる。 (2) According to the invention of claim 2, even if the piping length of the draw-up standpipe is short, the siphon action is efficiently given to the dredging drainage in the drainage side branch pipe because of having the throttle pipe part, In addition, it is stable against fluctuations in the flow rate of dredged drainage in the drainage horizontal branch pipe, and has the effect of increasing the flow rate of dredged drainage in the drainage horizontal branch pipe. When the length of the throttle pipe part is reduced to about 4/5 or less and the length of the throttle pipe part is set to 200 mm or more, such an effect is obtained when dredging drainage flows down the drainage side branch pipe at a flow rate of about 8 liters per minute. Effectively obtained. In addition, when the length of the throttle pipe section is about 600 mm or more and the flow rate of dredging drainage is about 8 liters per minute, the flow velocity in the drainage horizontal branch pipe is introduced as general data. Without being deposited in the pipe, it can be 0.6 m / s or more, which is said to provide a safe drainage state, and the soot in the drainage side branch pipe is easily transported. In addition, when discharging dredging drainage in the drainage horizontal branch pipe to another place through a drainage pipe with the same diameter pipe without the throttle pipe part of the drainage lateral branch pipe, Due to the change in the length of the tube, the siphon effect is easily interrupted.

（３）請求項３記載の発明によれば、厨芥粉砕装置が作動してないときには、厨芥粉砕装置に流入した排水が円滑に排水横枝管内に流下し難いことが生じ得るが、厨芥粉砕装置の排出口から排水横枝管に排水が流れたときに厨芥粉砕装置が作動すると、厨芥粉砕装置に流れ込んだ排水が厨芥粉砕装置の動力でその排水口から押し出され排水横枝管内の排水圧力を上昇させ円滑に流下するものとなるのであり、またこのように流下した排水は引き起こし立て管に達したときにサイホン作用を安定的に発生させてその流下を促進するものとなる。 (3) According to the invention described in claim 3, when the smashing device is not operating, the wastewater that has flowed into the smashing device may not flow smoothly into the drainage side branch pipe. When the waste crusher is activated when drainage flows from the discharge outlet to the drainage side branch pipe, the wastewater that flows into the waste crusher is pushed out of the drainage outlet by the power of the waste crusher, and the drainage pressure in the drainage side branch pipe is reduced. The drainage that has flowed down in this way causes the siphon action to be stably generated and promoted to flow down when it reaches the vertical pipe.

（４）請求項４記載の発明によれば、厨芥粉砕装置の作動による厨芥排水の排水が終了してその作動が停止したとき、サイホン作用により、厨芥粉砕装置と排水横枝管との間に形成されたトラップ内の水までが下流側へ引き出されることに起因してトラップの水封が破れることが生じ得るが、このような場合に、水供給手段からトラップ内に水が供給されるため、トラップの破封を防止することができる。 (4) According to the invention described in claim 4, when the drainage of the dredging drainage by the operation of the dredging crusher is finished and the operation is stopped, the siphon action causes a gap between the dredging crushing device and the drainage horizontal branch pipe. The trap water seal may be broken due to the water in the formed trap being drawn to the downstream side. In such a case, water is supplied from the water supply means into the trap. The trap can be prevented from being broken.

（５）請求項５記載の発明によれば、請求項２記載の発明を実現する上で寄与するものであり、また厨芥粉砕装置とは無関係に洗面器などの水回り器具の排水にも使用されるのであって、この場合にも、引落とし立て管の配管長さが短くても、絞り管部の存在により、サイホン作用が排水横枝管内の厨芥排水に効率よく付与され、しかも排水枝管内の厨芥排水の流量の変動などに対して安定的に発生し、排水横枝管内の厨芥排水の流速を速くする効果がある。 (5) According to the invention described in claim 5, it contributes to the realization of the invention described in claim 2, and is also used for draining water-related appliances such as a wash basin regardless of the pulverizer. Even in this case, the siphon action is efficiently given to the dredging drainage in the drainage side branch pipe due to the presence of the throttle pipe section, even if the length of the drainage standpipe is short, and the drainage branch It is generated stably against fluctuations in the flow rate of dredging drainage in the pipe, and has the effect of increasing the flow rate of dredging drainage in the drainage horizontal branch pipe.

図１はマンションに設置された本願の第１発明に係る厨芥排水の搬送システムの全体構成を示す説明図であり、図２は前記搬送システムの排水横枝管の末端を示す図である。   FIG. 1 is an explanatory view showing the overall configuration of a dredging drainage transport system according to a first invention of the present application installed in an apartment, and FIG. 2 is a diagram showing the end of a drainage horizontal branch pipe of the transport system.

図１において、１はマンションの台所に設置された流し台、２は流し台のシンクである。シンク２の下面にはシンク２の底面透口２ａを介して厨芥粉砕装置３が垂下状に固定されている。   In FIG. 1, 1 is a sink installed in the kitchen of an apartment, and 2 is a sink of the sink. On the lower surface of the sink 2, the pulverizer 3 is fixed in a suspended manner via a bottom surface through hole 2 a of the sink 2.

厨芥粉砕装置３は本体内の処理室の内方に厨芥を粉砕するための図示しない動力回転体が設けられており、前記処理室内にシンク２の底面透口２ａを通じて厨芥を投入した後に水を供給しながら動力回転体を回転させると、該動力回転体の回転により厨芥が粉砕されて厨芥排水が生成され、該厨芥排水が動力回転体の回転により厨芥粉砕装置３の排出口３ａから押し出されるものとなされている。   The soot crusher 3 is provided with a power rotating body (not shown) for crushing soot inside the processing chamber in the main body, and water is poured into the processing chamber through the bottom through-hole 2a of the sink 2. When the power rotator is rotated while being supplied, the soot is crushed by the rotation of the power rotator to generate the soot drainage, and the soot drainage is pushed out from the discharge port 3a of the soot pulverizer 3 by the rotation of the power rotator. It has been made.

４は台所の床面に敷設された管径３０Ａの排水横枝管であり、５はマンションの各階に到達するように設けられた垂直状の立て管である。このさい、排水横枝管４は必ずしも流れ方向の下り勾配を必要とするものではなく、逆勾配になされてもその程度によっては差し支えないものである。排水横枝管４の上流端はＵ字形のトラップ６を介して厨芥粉砕装置３の排出口３ａに接続されており、排水横枝管４の下流側の端末は垂直状の引起とし立て管４ａとなされ階下へ導かれている。   4 is a horizontal drainage pipe having a diameter of 30A laid on the floor of the kitchen, and 5 is a vertical standing pipe provided to reach each floor of the apartment. At this time, the drainage horizontal branch pipe 4 does not necessarily require a downward gradient in the flow direction, and even if it has a reverse gradient, there is no problem depending on the degree. The upstream end of the drainage horizontal branch pipe 4 is connected to a discharge port 3a of the pulverizer 3 through a U-shaped trap 6, and the downstream end of the drainage horizontal branch pipe 4 is a vertical riser and a vertical pipe 4a. It is led downstairs.

引落とし立て管４ａは図２に示すように、高さ途中位置ｐ１よりも下方部位をその上流側よりも小径となされた絞り管部ａ１となされており、該絞り管部ａ１はその管径Ｒ２を前記高さ途中位置ｐ１よりも上流側の管径Ｒ１の凡そ４／５以下となされ且つ絞り開始点から長さＬ１凡そ２００ｍｍ以上〜６００ｍｍ以下程度低い位置で立て管５に接続されている。なお、高さ途中位置ｐ１での絞りは管径が漸減するようなテーパ状の異径継ぎ手管を使用するのがよい。   As shown in FIG. 2, the draw-up stand pipe 4a is formed as a throttle pipe part a1 having a diameter lower than its upstream side at a position below the mid-height position p1, and the throttle pipe part a1 has a pipe diameter thereof. R2 is about 4/5 or less of the pipe diameter R1 upstream of the intermediate height position p1 and is connected to the standing pipe 5 at a position lower than the length L1 by about 200 mm to 600 mm in length L1. . It is preferable to use a tapered joint pipe having a tapered diameter so that the diameter of the pipe gradually decreases at the mid-height position p1.

７は制御回路であって、厨芥粉砕装置３の排出口３ａから下流側へ排水が流れたことを検出装置８で検出して厨芥粉砕装置３を自動的に起動させるものである。検出装置８は適宜な場所に設けて差し支えないものであるが、図示例ではトラップ６の入口に設けてある。   Reference numeral 7 denotes a control circuit, which detects that the wastewater has flowed downstream from the discharge port 3a of the pulverizer 3 with the detection device 8 and automatically activates the pulverizer 3. The detection device 8 may be provided at an appropriate location, but is provided at the entrance of the trap 6 in the illustrated example.

８は水供給手段であって、厨芥粉砕装置３から排水横枝管４に至る途中に形成されたトラップ６の内方に厨芥粉砕装置３の作動に関連して水を供給するものとなされている。さらに具体的には、厨芥粉砕装置３の運転が停止された時点から例えば数十秒後（凡そ２０秒程度）に自動的に例えば数秒間（凡そ５秒程度）、水を供給するものである。   Reference numeral 8 denotes water supply means for supplying water in relation to the operation of the pulverizer 3 to the inside of the trap 6 formed in the middle from the pulverizer 3 to the drainage side branch pipe 4. Yes. More specifically, water is automatically supplied, for example, for several seconds (about 5 seconds), for example, several tens of seconds (about 20 seconds) after the operation of the pulverizer 3 is stopped. .

次に上記した厨芥排水の搬送システムの使用例及び作用について説明する。
厨芥粉砕装置３の処理室内に厨芥を投入し、蛇口を開放操作するなどしてシンク２内に水を流量凡そ毎分８リットル程度で供給する。 Next, the usage example and effect | action of the above-mentioned dredged wastewater conveyance system are demonstrated.
Water is supplied into the sink 2 at a flow rate of approximately 8 liters per minute by, for example, opening the tap into the processing chamber of the pulverizer 3 and opening the faucet.

シンク２内に供給された水は排水となって底面透孔２ａを経て厨芥粉砕装置３の処理室内に流入し、この後、排出口３ａ、トラップ６、排水横枝管４を経て立て管５内に排出される。この排水の流れは検出手段８が検出し、この検出に関連して、制御回路７が厨芥粉砕装置３の動力回転体を回転させる。これにより、厨芥粉砕装置３は処理室内で厨芥排水を生成し、その排出口３ａから動力回転体の作動により押し出す。   The water supplied into the sink 2 becomes drainage and flows into the processing chamber of the pulverizer 3 through the bottom through-hole 2a, and then through the discharge port 3a, the trap 6 and the drainage lateral branch pipe 4 and the vertical pipe 5 Discharged inside. The flow of the waste water is detected by the detection means 8, and in connection with this detection, the control circuit 7 rotates the power rotator of the pulverizer 3. As a result, the soot pulverizer 3 generates soot drainage in the processing chamber and pushes it out from the discharge port 3a by the operation of the power rotator.

厨芥粉砕装置３の排出口３ａから押し出された厨芥排水は、排水横枝管４内に到達して、該管４内の排水の圧力を上昇させ、該排水の流下を促進する。しかし、排出口３ａから押し出される厨芥排水の圧力による排水流下の促進は排水横枝管４の下流側へ向け摩擦抵抗などに起因して漸次に減衰される。   The wastewater pushed out from the discharge port 3a of the waste crusher 3 reaches the drainage horizontal branch pipe 4 to increase the pressure of the wastewater in the pipe 4 and promote the flow of the wastewater. However, the promotion of the drainage flow due to the pressure of the drainage discharged from the discharge port 3a is gradually attenuated due to frictional resistance and the like toward the downstream side of the drainage lateral branch pipe 4.

排水横枝管４内を流下した厨芥排水はやがて引落とし立て管４ａの絞り管部ａ１内に到達し、該絞り管部ａ１内を空気と排水の２相状態で或いは満水状態で流下する。この流下が引落とし立て管４ａの長さＬ１に対応したサイホン水頭によるポテンシャルエネルギーに基づくサイホン作用を安定的且つ継続的に発生させる。
このサイホン作用は引落とし立て管４ａの下流端まで及ぶことから、排水横枝管４内の排水はこのサイホン作用で流下を促進される。しかし、このサイホン作用による排水流下の促進は排水横枝管４の上流側へ向け摩擦抵抗などに起因して漸次に減衰される。 The dredged wastewater that has flowed down the drainage horizontal branch pipe 4 eventually reaches the throttle pipe part a1 of the draw-up stand pipe 4a, and flows down in the throttle pipe part a1 in a two-phase state of air and drainage or in a full state. This flow down stably and continuously generates a siphon action based on potential energy by the siphon head corresponding to the length L1 of the draw-up standpipe 4a.
Since this siphon action extends to the downstream end of the draw-up standpipe 4a, the drainage in the drainage horizontal branch pipe 4 is promoted to flow down by this siphon action. However, the promotion of drainage flow due to the siphon action is gradually attenuated due to frictional resistance or the like toward the upstream side of the drainage lateral branch pipe 4.

したがって、排水横枝管４の上流側部分では厨芥粉砕装置３による排水の押出しによる排水の流下促進が効果的に図られ、一方、排水横枝管４の下流側部分では引落とし立て管４ａでのサイホン水頭に係るサイホン作用による流下促進が効果的に図られ、他方、排水横枝管４の長さ中央部分では厨芥粉砕装置３の排水の押出しによる流下促進とサイホン作用による流下促進の双方が各々幾分減衰された状態で作用し、これに対応した流下促進が図られる。この結果、排水横枝管４の長さ全長に亘って比較的一様な流下促進が図られて、厨芥排水は比較的大きな流速及び流量で排水横枝管４内を立て管５内へ向けて流下する。   Accordingly, in the upstream side portion of the drainage side branch pipe 4, the drainage of the drainage is effectively promoted by the extrusion of the drainage by the slag crushing device 3, while in the downstream side portion of the drainage side branch pipe 4, the dropping standpipe 4a is used. On the other hand, in the central part of the length of the drainage side branch pipe 4, both the flow promotion by the extrusion of the waste water from the pulverizer 3 and the flow promotion by the siphon action are achieved. Each acts in a somewhat damped state, and corresponding flow promotion is achieved. As a result, the flow is promoted relatively uniformly over the entire length of the drainage side branch pipe 4, and dredged drainage is directed at the drainage side branch pipe 4 into the vertical pipe 5 at a relatively high flow rate and flow rate. Flow down.

絞り管部ａ１において排水横枝管４内の厨芥排水の流量が変動しても、厨芥排水は安定的に２相状態流れ或いは満水状態流れとなり、サイホン作用が安定的に生成されるものとなる。絞り管部ａ１の長さが２００ｍｍ以上であるときは、２相状態流れ中の一塊の空気部分の長さが２００ｍｍを超えない限り、サイホン作用の低下は生じないと考えられる。排水横枝管４内の厨芥排水の流量が凡そ毎分８リットル程度であるときには、絞り管部ａ１における２相状態流れの一塊の空気部分の長さは２００ｍｍを超えることはなく、サイホン作用は安定的に生成されるものとなるのであり、このことは後述の実験結果によっても確認されている。このサイホン作用は引落とし立て管４ａの長さに対応して大小に変化する。絞り管部ａ１の長さが６００ｍｍ以下であるときは、２相状態流れの一塊の空気部分の長さが６００ｍｍを超えない限り、サイホン作用の低下は生じないと考えられるので、サイホン作用は一層安定的に生成されるものとなる。なお、引落とし立て管４ａの長さが２００ｍｍ〜８００ｍｍであるときは絞り管部ａ１の形成されない場合にはサイホン作用が安定的に得られないことが試験により確認されている。   Even if the flow rate of dredged drainage in the drainage horizontal branch pipe 4 fluctuates in the throttle pipe part a1, the dredged drainage stably becomes a two-phase flow or a full flow, and the siphon action is stably generated. . When the length of the throttle tube part a1 is 200 mm or more, it is considered that the siphon action does not decrease unless the length of the lump air portion in the two-phase state flow exceeds 200 mm. When the flow rate of dredged drainage in the drainage side branch pipe 4 is about 8 liters per minute, the length of the air portion of the two-phase flow in the throttle pipe part a1 does not exceed 200 mm, and the siphon action is This is generated stably, and this is confirmed by the experimental results described later. This siphon action changes depending on the length of the draw-up standpipe 4a. When the length of the throttle tube portion a1 is 600 mm or less, it is considered that the siphon action does not decrease unless the length of the air portion of the two-phase state flow exceeds 600 mm. It will be generated stably. It has been confirmed by tests that the siphon action cannot be stably obtained when the drawn tube 4a has a length of 200 mm to 800 mm and the throttle tube portion a1 is not formed.

本願の第２発明に係る厨芥排水の搬送システムは、図１に示すように、排水横枝管４の末端を引落とし立て管４ａとなして階下へ落とし、該引落とし立て管４ａの高さ途中位置ｐ１よりも下方の部位を、その上流側よりも小径となされた絞り管部ａ１となし、該絞り管部ａ１内の排水流下がサイホン作用の生成を促進させるものとした構成とするものであり、第１発明の場合と異なり必ずしも厨芥粉砕装置３を構成要素とするものではない。
このさいの各部の作用は第１発明のうち厨芥粉砕装置３を除外したものの作用と実質的に変わりない。 As shown in FIG. 1, the dredged drainage conveying system according to the second invention of the present application is arranged such that the end of the drainage horizontal branch pipe 4 becomes a draw-up stand pipe 4 a and drops downstairs, and the height of the draw-up stand pipe 4 a. The part below the intermediate position p1 is the throttle pipe part a1 having a smaller diameter than the upstream side thereof, and the drainage flow in the throttle pipe part a1 promotes the generation of siphon action. Unlike the case of the first invention, the pulverizer 3 is not necessarily a constituent element.
The operation of each part at this time is not substantially different from the operation of the first invention except for the crusher 3.

出願人は、この第２発明の引落とし立て管４ａに絞り管部ａ１を形成することの有効性を明確にするため、種々の条件下に、サイホン作用の発生について実験装置により試験を行った。   In order to clarify the effectiveness of forming the throttle tube part a1 in the draw-down standpipe 4a of the second invention, the applicant tested the occurrence of siphon action using various types of experimental equipment under various conditions. .

a: The generation of the siphon action was carried out by flowing water, and a sufficient time was taken to check whether the siphon action occurred.
b: The test was carried out three times, and when the siphon action occurred all three times, it was indicated by a mark ◯, when it occurred once or twice, it was indicated by a mark △, and when it did not occur, it was indicated by a mark X.
c: The flow rate was measured by allowing water to flow for a sufficient period of time and assuming that siphon action occurred.

e: The two-phase state was confirmed visually.

〈考察〉
ａ：サイホン作用について
図４から判断されるように、配管径を絞ることで、引落し立て管４の配管長さが短い状態で、サイホン作用を発生させることができる。また、サイホン作用の発生も確実である。
また排水横枝管４の径に拘わらず、径を絞ることで、サイホン作用を確実に発生させるには、図４に示すように、引落とし立て管４ａの配管径が２０Ａの場合、配管長さは６００ｍｍ以上必要である。しかし、配管径を１６Ａに絞ることで６００mm以下でもサイホン作用を発生させることができる。
また配管径を絞った状態では配管長さが２００ｍｍ以上でサイホン作用が持続し易い。
サイホン作用は、引落し立て管４の配管径、配管長さ、給水量によって変化する。
ｂ．流速
配管でごみを搬送するのに必要な流速は０．６ｍ／ｓとされている。
試験結果では、配管径を絞った状態で配管長さが６００ｍｍ程度のときこの流速が得られる。
ｃ：配管内残渣
一般的な排水勾配１／５０では、配管内残渣は１ｇ程度である。
図５から判断されるように、配管径を絞った状態では配管長さが２００mm以上でほぼ同等の残渣であると言える。
また、図５において配管径を絞る場合と、絞らない場合の残渣を比較する。配管径を絞った場合の配管長さ1００mmと、配管径を絞らない場合の配管長さ６００mmの残渣はほぼ等しい。配管径を絞ると配管長さが短くても効率良く搬送できている。 <Discussion>
a: About the siphon action As can be seen from FIG. 4, the siphon action can be generated in a state where the pipe length of the drawn-up stand pipe 4 is short by narrowing the pipe diameter. In addition, the occurrence of siphon action is also certain.
Further, in order to reliably generate the siphon action by reducing the diameter regardless of the diameter of the drainage horizontal branch pipe 4, as shown in FIG. 4, when the pipe diameter of the draw-up stand pipe 4a is 20A, the pipe length The length needs to be 600 mm or more. However, the siphon action can be generated even when the pipe diameter is reduced to 16 A even if it is 600 mm or less.
Further, when the pipe diameter is reduced, the siphon action is easily maintained when the pipe length is 200 mm or more.
The siphon action varies depending on the pipe diameter, the pipe length, and the amount of water supply of the draw-up standpipe 4.
b. Flow rate The flow rate required to transport the waste through the pipe is 0.6 m / s.
In the test results, this flow velocity is obtained when the pipe length is about 600 mm with the pipe diameter reduced.
c: Residue in piping With a general drainage gradient 1/50, the residue in piping is about 1 g.
As can be seen from FIG. 5, it can be said that when the pipe diameter is reduced, the pipe length is 200 mm or more and almost the same residue.
Further, in FIG. 5, the residue when the pipe diameter is reduced and when the pipe diameter is not reduced are compared. The pipe length of 100 mm when the pipe diameter is reduced and the pipe length of 600 mm when the pipe diameter is not reduced are almost equal. If the pipe diameter is reduced, it can be transported efficiently even if the pipe length is short.

ｄ：その他
従来のサイホン作用を用いた排水配管は排水のみであり、厨芥を含んだことを想定していない。今回の配管は厨芥搬送を考慮した形状であり、かつサイホン作用が持続し易い。
サイホン作用が持続する流量は８Ｌ／ｍｉｎ以上である。
図６に残渣量と配管流速のグラフを示す。管内流速が０．６ｍ／ｓで残渣量が１ｇ程度になる。
即ち、配管でごみを搬送するのに必要な流速０．６ｍ／ｓの場合の配管内残渣は、一般的な排水勾配１／５０の場合の配管内残渣と同じように約１ｇ程度となる。
よって、実際に必要な引落とし立て管４の長さは２０Ａから１６Ａに絞る場合４００ｍｍ以上、２５Ａから１６Ａに絞る場合は６００ｍｍ以上、３０Ａから１６Ａに絞る場合は１０００ｍｍ以上の配管長さが必要となる。 d: Others The conventional drainage pipe using siphon action is only drainage, and it is not assumed that it contains soot. The piping this time has a shape that takes into account the soot conveyance, and siphoning is easy to sustain.
The flow rate at which the siphon action continues is 8 L / min or more.
FIG. 6 shows a graph of the residual amount and the pipe flow rate. The flow rate in the tube is 0.6 m / s, and the amount of residue is about 1 g.
That is, the residue in the pipe at a flow rate of 0.6 m / s necessary for transporting the waste through the pipe is about 1 g as in the case of the general drainage gradient 1/50.
Therefore, the actual length of the draw-up pipe 4 is 400 mm or more when narrowing from 20A to 16A, 600 mm or more when narrowing from 25A to 16A, and 1000 mm or more when narrowing from 30A to 16A. Become.
