Description
本発明は、建築物における排水搬送システムに関する。 The present invention relates to a drainage conveyance system in a building.
大きなビルなどの建築物では、厨房から上下方向に距離があるゴミ捨て場まで、生ごみなどの厨芥類を台車などで運搬すると手間がかかる。 In buildings such as large buildings, it takes time to transport garbage, such as garbage, with a trolley, etc., from a kitchen to a garbage disposal site that is vertically spaced.
そこで厨房の近くに配置されたディスポーザと、ディスポーザから比較的粘性の高い泥状物を圧送可能なルーツポンプなどのポンプを含み、ディスポーザで細断した有機廃棄物と水との混合物（以下「ＤＳＰ排水」という）を、排水管を介して外部へ圧送するシステムが提案されている（特許文献１）。 Therefore, it includes a disposer placed near the kitchen and a pump such as a roots pump that can pump mud that is relatively viscous from the disposer, and a mixture of organic waste and water shredded by the disposer (hereinafter “DSP”). There has been proposed a system that pumps the waste water (referred to as “drainage”) to the outside through a drain pipe (Patent Document 1).
しかしながら、建築物内に複数のディスポーザがある場合に、各ディスポーザから外部へ延びる排水管を配管すると、配管総延長が増大するとともに、建物の面積のうち排水管の断面で占める割合が増加し、好ましくない。 However, when there are multiple disposers in the building, piping drainage pipes that extend from each disposer to the outside increases the total length of the pipes and increases the proportion of the area of the building in the cross section of the drainage pipes. It is not preferable.
これに対して、マンションなどの台所排水搬送システムとして、各住宅毎に設置したディスポーザからそれぞれ従管路を介して横主管路の基部へＤＳＰ排水を集めるとともに、この横主管路の基部に固液分離装置を配置したものが提案されている（特許文献２）。固液分離装置で分離した固形成分は、屋上などに貯蔵した雨水などで、高度差を利用した水勢を利用して押し流すようにしている。 On the other hand, as a drainage system for kitchen drainage in condominiums, etc., DSP wastewater is collected from the disposer installed in each house via the secondary pipe to the base of the horizontal main pipe, and solid liquid is added to the base of the horizontal main pipe. The thing which has arrange | positioned the separation apparatus is proposed (patent document 2). The solid components separated by the solid-liquid separation device are washed away using rainwater stored on the rooftop or the like using the water force utilizing the altitude difference.
特許文献１のように建築物の上部から下部へ配管を縦設する場合に、配管のルートの途中に各種設備など配管上の障害物があったときには、配管の一部を横向きにして障害物を迂回する必要がある。そうすると、迂回用の横管部分を含む管路系全体の流体抵抗が増加し、圧送ポンプの負荷が大となる。また横管部分に有機廃棄物が詰まってしまう可能性がある。 When piping is installed vertically from the upper part to the lower part of the building as in Patent Document 1, if there are obstacles on the piping such as various facilities in the middle of the piping route, the part of the piping is turned sideways and the obstacle It is necessary to bypass. If it does so, the fluid resistance of the whole pipeline system containing the side pipe part for a detour will increase, and the load of a pressure pump will become large. In addition, there is a possibility that the horizontal pipe part is clogged with organic waste.
予めそうした障害物を避けた直線的な配管ルートが選択できればよいが、建物の階数が多くなると、そうした配管ルートをとることが出来ないことがある。 It is only necessary to select a straight piping route that avoids such obstacles in advance. However, if the number of floors of the building increases, such a piping route may not be taken.
特許文献２の固液分離装置付きの排水搬送システムは、比較的有機物の濃度が高い業務用の厨房排水に適用することが難しい。厨房排水の量が固液分離装置の処理能力を超えてしまう可能性があるからである。 The drainage conveyance system with a solid-liquid separator of Patent Document 2 is difficult to apply to commercial kitchen drainage with a relatively high concentration of organic matter. This is because the amount of kitchen wastewater may exceed the processing capacity of the solid-liquid separator.
前述のように複数の従管路から一本の主管路へ排水を集水する管路系の構造は、省スペースという点では有利であるが、有機物を多量に含むＤＳＰ排水が管に詰らないようにするためには、ポンプの圧力を高くしなければならず、そうすると下流側の従管路へ逆流してしまうおそれもある。 As described above, the structure of the pipeline system that collects drainage from a plurality of sub-pipes to one main pipeline is advantageous in terms of space saving, but DSP drainage containing a large amount of organic substances is clogged in the pipe. In order to avoid this, it is necessary to increase the pressure of the pump, and there is a risk that it will flow backward to the downstream follower.
本発明の第１の目的は、ＤＳＰ排水を複数の横方向の従管路から縦方向の主管路に集めるように設け、かつ建築物の特定箇所を迂回するように構成した排水搬送システムであって、排水の搬送をスムーズに行えるものを提案することである。 A first object of the present invention is a drainage transport system configured to collect DSP drainage from a plurality of lateral follower pipes to a vertical main duct and to bypass a specific part of a building. It is to propose a system that can smoothly transport wastewater.
本発明の第２の目的は、上記構成の排水搬送システムであって、管路を効果的に洗浄できるものを提案することである。 The second object of the present invention is to propose a drainage conveyance system having the above-described configuration, which can effectively clean a pipeline.
本発明の第３の目的は、上記構成の排水搬送システムであって、有機廃棄物が詰まりにくいものを提案することである。 The third object of the present invention is to propose a drainage transport system having the above-described configuration, which is less likely to be clogged with organic waste.
まず本発明の基本構成を説明する。この基本構成は、
建築物の縦方向一部から下へ延びる第１縦主管部の下端部を拡開して中継槽とし、この中継槽から横方向に延びる第１横主管部を経て排水口へ至る主管路と、
上記建築物の一部に設置された複数のディスポーザで発生したＤＳＰ排水を第１縦主管部へ圧送するために、各ディスポーザ毎に配管した横向きの従管路と、
中継槽に入ったＤＳＰ排水を第１横主管部へ圧送するための搬送ポンプと、
上記第１縦主管部の上部に開口した上流側通気口及び中継槽に開口した下流側通気口と、
を具備し、
従管路から主管路へ連続する管路系のうち、従管路及び第１横主管部は、それぞれＤＳＰ排水を圧送するように設け、また第１縦主管部は、上記通気口を介して外部と連通させ、ＤＳＰ排水が重力作用により落下する開放流路に形成した排水搬送システムである。
First, the basic configuration of the present invention will be described. This basic configuration is
A lower main pipe portion extending downward from a part of the vertical direction of the building is expanded to form a relay tank, and the main pipe line extending from the relay tank to the drainage port through the first horizontal main pipe portion extending in the horizontal direction; ,
In order to pressure-feed DSP drainage generated by a plurality of disposers installed in a part of the building to the first vertical main pipe section, a horizontal slave pipe piped for each disposer,
A transport pump for pumping the DSP drainage that has entered the relay tank to the first horizontal main pipe section;
An upstream vent opening in the upper part of the first vertical main pipe section and a downstream vent opening in the relay tank;
Comprising
Of the pipeline system that continues from the secondary pipeline to the primary pipeline, the secondary pipeline and the first horizontal main pipeline section are provided so as to pump DSP drainage, respectively, and the first vertical main pipeline section is provided via the vent hole. This is a drainage conveyance system formed in an open flow path that communicates with the outside and in which DSP drainage falls due to gravity .
上記基本構成では、図１に示す複数の従管路２から主管路６へ流れる排水が、横向きの従管路内を圧送され、第１縦主管部６Ａ内を圧力開放状態で落下し、第１横主管部６Ｂで再び圧送される仕組みを提案する。これにより第１縦主管部での逆流を避けている。通常の排水では、落下の勢いを削がないように縦管と横管との間にエルボ管を適用すればよいが、ＤＳＰ排水の場合には有機物がエルボ管に付着して閉塞させる虞がある。そこで本手段では、第１縦主管部の下端部を拡開して中継槽１４としている。 In the above basic configuration , the drainage flowing from the plurality of secondary pipes 2 to the main pipe 6 shown in FIG. 1 is pumped through the sideways secondary pipe, falls in the first vertical main pipe 6A in a pressure-released state, A mechanism is proposed in which the pressure is again fed by the one horizontal main pipe portion 6B. This avoids backflow in the first vertical main pipe. In normal drainage, an elbow pipe may be applied between the vertical and horizontal pipes so as not to reduce the momentum of falling. However, in the case of DSP drainage, organic substances may adhere to the elbow pipe and block it. is there. Therefore, in this means, the lower end portion of the first vertical main pipe portion is expanded to form the relay tank 14.
「主管路」は建築物の一定範囲で生ずるＤＳＰ排水を集めるための管路、「従管路」は主管路に連なる管路である。主管路は、一本の管路であることが望ましい。図示の従管路はディスポーザを含んでいるが、従管路とディスポーザとを別個の物としても構わない。「通気口」は第１縦主管部内に入った排水の搬送圧力を解消することが可能な面積を有する。「中継槽」は排水及び洗浄水の液留めとして第１縦主管部及び第１横主管部より大内径に形成する。「搬送ポンプ」は容積形ポンプとするとよい。
そして第１の手段は、上記基本構成を有し、かつ

中継槽は第１横主管部よりも大径であって、中継槽の底部側から第１横主管部が延びており、
また上記搬送ポンプは、少なくとも中継槽中の堆積物である固形成分とＤＳＰ排水との混合流体、中継槽内の空気、中継槽内の洗浄水である水のいずれをも第１横主管部へ圧送することが可能な流体ポンプとしている。
The “main pipeline” is a pipeline for collecting DSP drainage generated in a certain range of the building, and the “secondary pipeline” is a pipeline connected to the main pipeline. The main pipeline is preferably a single pipeline. Although the illustrated follower line includes a disposer, the follower line and the disposer may be separate. The “vent hole” has an area capable of eliminating the transfer pressure of the wastewater that has entered the first vertical main pipe. The “relay tank” is formed to have a larger inner diameter than the first vertical main pipe portion and the first horizontal main pipe portion as a drainage and washing water retainer. The “conveying pump” may be a positive displacement pump.
The first means has the above basic configuration, and
The first vertical main pipe part extends downward from the upper layer part of the building to the middle floor of the building, and passes through the relay tank and the first horizontal main pipe part located on the middle floor to the lower layer side of the building Communicated with
The relay tank has a larger diameter than the first horizontal main pipe portion, and the first horizontal main pipe portion extends from the bottom side of the relay tank,
In addition, the transfer pump supplies at least the mixed fluid of the solid component that is the deposit in the relay tank and the DSP drainage, the air in the relay tank, and the water that is the cleaning water in the relay tank to the first horizontal main pipe section. The fluid pump is capable of being pumped.
第２の手段は、上記基本構成を有し、かつさらに上記中継槽より上流の管路系の適所に設けた洗浄水供給手段と、この洗浄水供給手段及び搬送ポンプを制御する制御装置とを具備し、
上記搬送ポンプは、少なくとも中継槽中の堆積物である固形成分とＤＳＰ排水との混合流体、中継槽内の空気、中継槽内の洗浄水である水のいずれをも第１横主管部へ圧送することが可能な流体ポンプであり、
上記制御装置は、
搬送ポンプを作動させて、中継槽の液位が中継槽の底面近くになるまで中継槽内の堆積物及びＤＳＰ排水を排出する第１の工程、

洗浄水供給手段を停止させるとともに搬送ポンプを作動させて中継槽の液位が中継槽の底面近くになるまで洗浄水を排出するとともに中継槽内へ空気を導入する第３の工程、
を実行させることができるように構成している。
The second means has the above basic configuration , and further includes a cleaning water supply means provided at an appropriate position in the pipeline system upstream from the relay tank, and a control device for controlling the cleaning water supply means and the transport pump. Equipped,
The transfer pump pumps at least all of the mixed fluid of the solid component and DSP drainage that are the deposits in the relay tank, the air in the relay tank, and the water that is the cleaning water in the relay tank to the first horizontal main pipe section. Is a fluid pump capable of

A third step of stopping the cleaning water supply means and operating the transport pump to discharge the cleaning water and introduce air into the relay tank until the liquid level of the relay tank is near the bottom of the relay tank;
Is configured to be executed.
本手段は、中継槽の洗浄機能に関して提案する。堆積物・水・空気の何れも圧送できるルーツポンプなどを用いてＤＳＰ排水を底面近くまで排水し、次に洗浄水を貯水して底面近くまで排水する。その制御手法は図４の説明で述べる。洗浄水を一気に放水するので、洗浄機能が高まる。これに対して水中ポンプを用いることも考えられるが、水槽の容積を十分に確保しないとエアロックを生じる虞がある。「底面近くまで…排出する」とは、底面が露出するまで排出することを含む。 This means is proposed regarding the cleaning function of the relay tank. The DSP drainage is drained to the bottom using a Roots pump that can pump sediment, water, and air, and then the wash water is stored and drained to the bottom. The control method will be described with reference to FIG. Since the cleaning water is discharged at once, the cleaning function is enhanced. On the other hand, it is conceivable to use a submersible pump, but there is a risk that an air lock will occur if the volume of the water tank is not sufficiently secured. “Discharging close to the bottom surface” includes discharging until the bottom surface is exposed.
第３の手段は、第１の手段又は第２の手段を有し、かつ中継槽は、制御装置と接続された液位計測手段を有し、
かつ第１縦主管部のうち中継槽に接続する部分を、鉛直方向に対して３０°〜４５°の角度をなす傾斜管路に形成している。
The third means has the first means or the second means, and the relay tank has the liquid level measuring means connected to the control device,
And the part connected to a relay tank among the 1st vertical main pipe parts is formed in the inclined pipe line which makes the angle of 30 degrees-45 degrees with respect to a perpendicular direction.
本手段では、図２に示すように、中継槽への流入管路を傾斜管１２とすることを提案している。これにより槽内の液面が波立つことを抑制し、液位の測定を正確に測定することができる。 In this means, as shown in FIG. 2, it is proposed that the inflow pipe line to the relay tank is an inclined pipe 12. Thereby, it is possible to suppress the liquid level in the tank from rising and to accurately measure the liquid level.
第４の手段は、
建築物の縦方向一部から下へ延びる第１縦主管部の下端部を拡開して中継槽とし、この中継槽から横方向に延びる第１横主管部を経て排水口へ至る主管路と、
上記建築物の一部に設置された複数のディスポーザで発生したＤＳＰ排水を第１縦主管部へ圧送するために、各ディスポーザ毎に配管した横向きの従管路と、
中継槽に入ったＤＳＰ排水を第１横主管部へ圧送するための搬送ポンプと、
上記第１縦主管部の上部に開口した上流側通気口及び中継槽に開口した下流側通気口と、を具備し、
従管路から主管路へ連続する管路系のうち、従管路及び第１横主管部は、それぞれＤＳＰ排水を圧送するように設け、また第１縦主管部は、上記通気口を介して外部と連通させ、ＤＳＰ排水が重力作用により落下する開放流路に形成したこと、を基本構成とする排水搬送システムにおいて、
複数の従管路から第１縦主管部を経て第１横主管部へ至る管区を、最も上側の管区として、複数の従管路から縦主管部を経て横主管部へ至る複数の管区を建築物の上側から下側へ構築しており、
最も上側の管区では、一番上の従管路との合流箇所より上方に第１縦主管部分に上流側通気口を開口して、上記基本構成を有しており、
２番目以降の管区では、その縦主管部を、当該管区より一つ上の管区の横主管部の末端に連続させ、かつ当該管区の主管路部分及び従管路は、上流側通気口を省略することを除いて最も上側の主管路部分及び従管路に関して上記基本構成を有する。
The fourth means is
A lower main pipe portion extending downward from a part of the vertical direction of the building is expanded to form a relay tank, and the main pipe line extending from the relay tank to the drainage port through the first horizontal main pipe portion extending in the horizontal direction; ,
In order to pressure-feed DSP drainage generated by a plurality of disposers installed in a part of the building to the first vertical main pipe section, a horizontal slave pipe piped for each disposer,
A transport pump for pumping the DSP drainage that has entered the relay tank to the first horizontal main pipe section;
An upstream vent opening in the upper portion of the first vertical main pipe section and a downstream vent opening in the relay tank;
Of the pipeline system that continues from the secondary pipeline to the primary pipeline, the secondary pipeline and the first horizontal main pipeline section are provided so as to pump DSP drainage, respectively, and the first vertical main pipeline section is provided via the vent hole. In the drainage conveyance system having a basic configuration that the DSP drainage is formed in an open flow path in which it falls by gravity due to communication with the outside,
Building a plurality of sub-divisions from a plurality of sub-pipes to a main cross-pipe section through a plurality of sub-pipes to a main cross-pipe section as the uppermost sub-division through the first vertical main pipe section to the first horizontal main pipe section has built from the upper side to the lower side of the object,
In the uppermost section, the upstream side vent is opened in the first vertical main pipe portion above the junction with the uppermost subway, and has the above basic configuration.
In the second and subsequent divisions, the longitudinal main pipe portion is continued to the end of the horizontal main pipe portion of the division immediately above the division, and the upstream side vent is omitted in the main pipeline portion and the secondary pipeline in the division. Except for the above , the above-mentioned basic configuration is provided for the uppermost main pipeline portion and the secondary pipeline .
本手段では、図５に示す如く複数の従管路と一本の縦主管部と一本の横主管部とからなる管区Ａ１、Ａ２…を順次連続させて構築することを提案している。これにより配管パターンがさらに増大する。また横主管部の前に下流側通気口を有する中継槽を配置することで管路系を複数管区に区切ったから、各管区毎の堆積物を除去するための搬送圧力を加えれば足りる。中継槽の洗浄を制御する制御装置は、各管区毎に設けてもよく、また建築物全体で一つの制御装置を設けてもよい。 In this means, as shown in FIG. 5, it is proposed that the sections A 1 , A 2 ... Consisting of a plurality of secondary pipes, one vertical main pipe part, and one horizontal main pipe part are successively constructed. Yes. This further increases the piping pattern. In addition, since the conduit system is divided into a plurality of sections by arranging a relay tank having a downstream side vent in front of the horizontal main pipe section, it is sufficient to apply a transport pressure for removing the deposits in each section. A control device for controlling cleaning of the relay tank may be provided for each of the districts, or one control device may be provided for the entire building.
第１の手段に係る発明によれば、従管路から主管路を経て排水口へ至る管路系のうち横主管部の上流側に通気口付き中継槽を配したから、管路系の上流側のポンプから下流まで管が詰まらないように送水する場合と比べて搬送に要する圧力を低減できる。 According to the first aspect of the invention, since the relay tank with the vent is arranged on the upstream side of the horizontal main pipe portion in the pipe system from the sub pipe to the drain through the main pipe, the upstream of the pipe system Compared with the case where water is fed from the side pump to the downstream side, the pressure required for conveyance can be reduced.
第２の手段に係る発明によれば、開放流路である第１縦主管部の下端部の中継槽内へ空気を導入するから、槽内の液位が底面近くになるまで水位を下げることができ、中継槽及び第１横主管部内から堆積物を効率よく除去できる。 According to the invention relating to the second means, since air is introduced into the relay tank at the lower end of the first vertical main pipe part which is an open flow path, the water level is lowered until the liquid level in the tank is close to the bottom surface. And deposits can be efficiently removed from the relay tank and the first horizontal main pipe.
第３の手段に係る発明によれば、第１縦主管部のうち中継槽に接続する部分を傾斜管としたから、液位の測定を正確に行うことができる。 According to the third aspect of the invention, since the portion connected to the relay tank in the first vertical main pipe portion is the inclined pipe, the liquid level can be accurately measured.
第４の手段に係る発明によれば、従管路と縦主管部と横主管部とからなる管区を複数連続して構築したから、建築物における配管パターンの自由度を確保できるとともに、管路系全体を効果的に洗浄できる。 According to the invention pertaining to the fourth means, since a plurality of sections comprising the secondary pipe, the vertical main pipe section, and the horizontal main pipe section are continuously constructed, the degree of freedom of the piping pattern in the building can be secured, and the pipe line The entire system can be cleaned effectively.

図示例の第１縦主管部６Ａは、上流側通気口８を上端に開口する垂直管１０と、垂直管から斜め下方へ突出する傾斜管１２と、傾斜壁部の下端に連結した中継槽１４とで形成する。 The first vertical main pipe portion 6A in the illustrated example includes a vertical pipe 10 that opens the upstream side vent port 8 at the upper end, an inclined pipe 12 that projects obliquely downward from the vertical pipe, and a relay tank 14 that is connected to the lower end of the inclined wall portion. And formed with.
上記垂直管１０は、複数階に亘って長く延び、各階のディスポーザ４から延出した複数の従管路２とそれぞれ連結している。垂直管１０は、基本的に直筒状の管壁で形成する。但し各従管路の合流に応じて、合流点下方の管壁をその上流側に比べて太い管（好ましくは同心大径管）とすることができる。 The vertical pipe 10 extends long over a plurality of floors, and is connected to a plurality of secondary pipe lines 2 extending from the disposer 4 on each floor. The vertical tube 10 is basically formed of a straight tube wall. However, the pipe wall below the junction can be made thicker than the upstream side (preferably a concentric large-diameter pipe) in accordance with the merging of the secondary pipes.
上記垂直管１０の上端部には、上流側通気口８を開口する。これにより複数のディスポーザからのＤＳＰ排水がスムーズに流れるようにしている。上流側通気口８と最も上側の従管路２との合流箇所との間には逆流防止に必要な距離を確保する。図示の例では、垂直管が建築物の外壁を貫通して、上流側通気口８を建築物の外へ開放させるとよい。 An upstream vent 8 is opened at the upper end of the vertical pipe 10. As a result, DSP drainage from a plurality of disposers flows smoothly. A distance necessary for preventing the backflow is secured between the upstream vent 8 and the junction of the uppermost secondary pipe 2. In the illustrated example, the vertical pipe may penetrate the outer wall of the building to open the upstream side vent 8 to the outside of the building.
上記傾斜管１２は、垂直管１０内から落下したＤＳＰ排水を減速させる機能を有し、鉛直方向に対して傾斜角θで傾いている。中継槽内の水面の擾乱を低減するためである。傾斜角θは、３０〜４５°程度とするとよい。傾斜角が小さ過ぎると減速効果が足りなくなり、傾斜角度が大き過ぎると管内に有機物が付着し易くなるからである。 The inclined pipe 12 has a function of decelerating DSP drainage that has dropped from the vertical pipe 10 and is inclined at an inclination angle θ with respect to the vertical direction. This is to reduce disturbance of the water surface in the relay tank. The inclination angle θ is preferably about 30 to 45 °. This is because if the tilt angle is too small, the deceleration effect is insufficient, and if the tilt angle is too large, organic substances easily adhere to the inside of the pipe.
上記中継槽１４は、図２に示すように第１縦主管部６Ａの管壁の下端部を拡開して大内径部に形成している。図示の中継槽１４は、傾斜管１２の下端部から斜め下方へ広がる頂壁１６と、頂壁１６から垂下する大径周壁１８と、この大径周壁の下端に付設した内向きフランジ状の底壁２０とで形成しており、この底壁の内縁を第１横主管部６Ｂに接続している。もっともこの構成は適宜変更することができる。 As shown in FIG. 2, the relay tank 14 is formed to have a large inner diameter portion by expanding the lower end portion of the tube wall of the first vertical main pipe portion 6A. The illustrated relay tank 14 includes a top wall 16 that extends obliquely downward from the lower end of the inclined pipe 12, a large-diameter peripheral wall 18 that hangs down from the top wall 16, and an inward flange-shaped bottom attached to the lower end of the large-diameter peripheral wall. It forms with the wall 20, and the inner edge of this bottom wall is connected to the 1st horizontal main pipe part 6B. However, this configuration can be changed as appropriate.
上記中継槽１４の頂壁１６の一部には、下流側通気口２４を開口している。この下流側通気口２４は、少なくとも垂直管１０の流路面積、及び傾斜管１２の下面で形成する流入口２２の面積と同程度の開口面積を有する。 A downstream vent 24 is opened in a part of the top wall 16 of the relay tank 14. The downstream vent 24 has an opening area that is at least as large as the flow path area of the vertical pipe 10 and the area of the inlet 22 formed by the lower surface of the inclined pipe 12.
図示例では、下流側通気口２４から通気管２６を上方へ突出しており、下流側通気口２４からの排水の漏れ出しを防止している。 In the illustrated example, the vent pipe 26 protrudes upward from the downstream vent 24 to prevent drainage of the drainage from the downstream vent 24.
上記中継槽１４の底壁２０は、図３に示すように、流出口２８に向かって水平面に対して傾斜している。傾斜角度θ２は３０°以上とするとよい。この流出口２８は、エルボ管３０を介して、第１横主管部に連続させている。これにより、中継槽１４内の堆積物を容易に吸引することができる。また、流出口２８の径Ｄは、流出口に連なる管の径ｄｓの１．５倍以上とするとよく、またその管の管軸に対して流出口２８を偏心させることが望ましい。 As shown in FIG. 3, the bottom wall 20 of the relay tank 14 is inclined with respect to the horizontal plane toward the outlet 28. The inclination angle theta 2 or equal to 30 ° or more. The outlet 28 is connected to the first horizontal main pipe portion via the elbow pipe 30. Thereby, the deposit in the relay tank 14 can be sucked easily. The diameter D of the outlet 28, when 1.5 times or more the diameter d s of the tube leading to the outlet may also be to be desirable decentering the outlet 28 to the tube axis of the tube.
さらに中継槽１４には、水位測定手段３２を設けている。図２に示す水位測定手段３２は、上下方向の複数箇所（図示例では２箇所）にフロートスイッチＦ１、Ｆ２…を有し、中継槽内の液面がその液位に達したことを検知するように構成している。この構成は適宜変更することができる。なお、中継槽のうち水位測定手段３２の横側方を囲うように図示しない仕切り板を設けてもよい。
水位測定手段は、中継槽１４が空槽になったことを検知できるようにするとよい。図示例の場合には、水位がＬＷＬになったことを検知した時点から、搬送ポンプの搬送能力に応じた一定のタイムラグをおいて、中継槽１４が空槽になったものと推定することができる。
Further, the relay tank 14 is provided with a water level measuring means 32. The water level measuring means 32 shown in FIG. 2 has float switches F 1 , F 2 ... At a plurality of locations in the vertical direction (2 locations in the illustrated example), and the liquid level in the relay tank has reached that level. It is configured to detect. This configuration can be changed as appropriate. In addition, you may provide the partition plate which is not illustrated so that the horizontal side of the water level measurement means 32 may be enclosed among relay tanks.
The water level measuring means may be configured to detect that the relay tank 14 is empty. In the case of the illustrated example, it can be estimated that the relay tank 14 has become an empty tank after a certain time lag corresponding to the transfer capability of the transfer pump from the time when it is detected that the water level has become LWL. it can.
エルボ管３０の出口には、搬送ポンプ３４として定量性に優れた容積形ポンプを設ける。限られた時間内に所定量の流体を確実に搬送できることが排水搬送システムの中継槽として重要だからである。容積形ポンプのうちでもエアロックが起きにくいルーツポンプが特に好適である。 At the outlet of the elbow pipe 30, a positive displacement pump excellent in quantitativeness is provided as the transport pump 34. This is because it is important as a relay tank of a drainage transfer system that a predetermined amount of fluid can be reliably transferred within a limited time. Of the positive displacement pumps, a roots pump that is less likely to cause an air lock is particularly suitable.
ルーツポンプは、従来公知の如く、楕円形のケーシング内を例えば２つの瓢箪形のローターが回転することによる容積変化により気体や液体を圧送するものである。この作動原理から吸引力が強く、液体に空気が混合しても連続吸引することができ、エアロックを生じにくい。またローターをポリウレタンゴム製ロータとすることで、小さな固形物が混入してもポンプ内部で詰らないものが提案されている（特許文献３）。 As is well known in the art, the Roots pump pumps gas or liquid by volume change caused by, for example, rotation of two bowl-shaped rotors in an elliptical casing. Due to this operating principle, the suction force is strong, and even if air is mixed with the liquid, continuous suction can be performed, and air lock is hardly generated. In addition, by using a polyurethane rubber rotor as the rotor, it has been proposed that even if a small solid is mixed, the rotor does not clog (Patent Document 3).
中継槽１４の排水手段として、仮に通常の水中吸引式のポンプを採用すると、エアロックを避けるためにポンプ設置箇所より高く設定した位置までしか排水を行うことができない。容積形ポンプ、例えばルーツポンプのような気液兼用の圧送ポンプを用いることで、中継槽をコンパクト化することが可能となる。 If a normal submersible suction pump is adopted as the drainage means of the relay tank 14, the drainage can be performed only to a position set higher than the pump installation location in order to avoid an air lock. The relay tank can be made compact by using a positive displacement pump such as a positive displacement pump such as a roots pump.
上記第１縦主管部６Ａは管路系の外に連通する開放流路である。本明細書において「開放流路」とは、水が流れている状態で流路の上流側及び下流側の少なくとも一方或いは双方が管路系の外部と連通している流路という程度の意味である。本実施形態では、第１縦主管部６Ａの上下両端部に上記上流側通気口８及び下流側通気口２４を開口している。 The first vertical main pipe portion 6A is an open flow path communicating with the outside of the pipeline system. In this specification, “open channel” means a channel in which at least one or both of the upstream side and the downstream side of the channel are in communication with the outside of the pipeline system in a state where water is flowing. is there. In the present embodiment, the upstream side vent port 8 and the downstream side vent port 24 are opened at the upper and lower end portions of the first vertical main pipe portion 6A.
上記第１横主管部６Ｂは、搬送ポンプ３４から配管上の障害物Ｏを迂回するために横方向に延びている。 The first horizontal main pipe portion 6B extends in the horizontal direction to bypass the obstacle O on the pipe from the transport pump 34.
上記延長管部６Ｃは、第１横主管部６Ｂの端部から建築物の下層部へ延びており、その下端部を排出口３６としている。この排出口３６は、後述の水槽Ｔの上方に配置している。延長管部６Ｃは必ずしも垂直に形成する必要はない。 The extension pipe portion 6C extends from the end portion of the first horizontal main pipe portion 6B to the lower layer portion of the building, and the lower end portion serves as a discharge port 36. The discharge port 36 is disposed above a water tank T described later. The extension pipe portion 6C is not necessarily formed vertically.
給水手段３８は、図１に示す例では給水タンク４０と給水管４２で形成しており、給水管４２の先部は第１縦主管部６Ａに接続している。しかしながら、その構成は適宜変更することができる。例えば、ディスポーザの給水部で兼ねることもできる。 In the example shown in FIG. 1, the water supply means 38 is formed by a water supply tank 40 and a water supply pipe 42, and the tip of the water supply pipe 42 is connected to the first vertical main pipe portion 6A. However, the configuration can be changed as appropriate. For example, it can also serve as the water supply section of the disposer.
制御装置４６は、従管路付きポンプ４ｄと搬送ポンプ３４と給水手段３８とを制御し、後述する「通常の排水モード」及び「洗浄モード」の運転及び切替えを行うことができる。また制御装置は中継槽の水位測定手段３２と接続されている。制御装置４６は、図４に示す制御のフローチャートを実行可能なコンピュータ（マイクロコンピュータを含む）で構成することが好適である。制御装置の具体的な機能は、本発明のシステムの作用の説明の中で述べる。 The control device 46 can control and switch the “normal drainage mode” and the “cleaning mode” to be described later by controlling the sub-pipe pump 4d, the transport pump 34, and the water supply means 38. The control device is connected to the water level measuring means 32 of the relay tank. The control device 46 is preferably composed of a computer (including a microcomputer) capable of executing the control flowchart shown in FIG. Specific functions of the control device will be described in the description of the operation of the system of the present invention.
上記構成によれば、利用者がディスポーザ４に有機廃棄物を投入すると、これがディスポーザで細断され、ＤＳＰ排水として従管路付きポンプ４ｄにより第１縦主管部６Ａ側へ圧送される。このとき管路系内の空気が上流側通気口８及び下流側通気口２４を介して外部へ排出されるので、ＤＳＰ排水の圧送はスムーズに行われる。 According to the above configuration, when the user throws organic waste into the disposer 4, the organic waste is shredded by the disposer and is pumped to the first vertical main pipe portion 6 </ b> A side as a DSP drainage by the pump 4 d with a secondary pipe. At this time, since the air in the pipeline system is discharged to the outside through the upstream side vent 8 and the downstream side vent 24, the DSP drainage is smoothly pumped.
第１縦主管部６Ａの垂直管１０内に入ったＤＳＰ排水は、搬送圧力を失い、重力作用のみで垂直管１０内を落下する。落下したＤＳＰ排水は傾斜管１２内へ入り、やや減速して中継槽１４内に入る。中継槽１４内に入ったＤＳＰ排水は、中継槽１４の底面に開口した流出口２８を経由して、搬送ポンプ３４により強力に吸引され、さらに第１横主管部６Ｂ内を強制的に搬送される。 The DSP drainage that has entered the vertical pipe 10 of the first vertical main pipe section 6A loses the conveyance pressure and falls in the vertical pipe 10 only by the gravitational action. The dropped DSP drainage enters the inclined pipe 12 and enters the relay tank 14 with a slight deceleration. The DSP wastewater that has entered the relay tank 14 is strongly sucked by the transfer pump 34 via the outlet 28 that opens at the bottom of the relay tank 14, and is forcibly transferred in the first horizontal main pipe section 6B. The
上記制御装置４６は、通常の排水モードにおいて、水位測定手段３２により中継槽内の水位を監視し、搬送ポンプ３４の作動をコントロールする。標準的な運転パターンとして、中継槽１４内の水位が図２に示すＬＷＬより下がったときに搬送ポンプ３４を停止し、ＬＷＬ以上となったときに搬送ポンプ３４を作動させることが好適である。搬送ポンプであるルーツポンプは、空槽でもロックすることはないが、省エネルギーの点から無駄な動作は省くべきだからである。 The control device 46 monitors the water level in the relay tank by the water level measuring means 32 and controls the operation of the transport pump 34 in the normal drainage mode. As a standard operation pattern, it is preferable to stop the transport pump 34 when the water level in the relay tank 14 falls below the LWL shown in FIG. 2, and to operate the transport pump 34 when the water level becomes LWL or higher. This is because the roots pump, which is a transfer pump, does not lock even in an empty tank, but wasteful operations should be omitted from the viewpoint of energy saving.
また、中継槽１４内の水位がＨＷＬを超えたときには、中継槽からの排水の漏出を避けるための措置を採る。これについては後述する。 Moreover, when the water level in the relay tank 14 exceeds HWL, measures are taken to avoid leakage of drainage from the relay tank. This will be described later.
上記第１横主管部６Ｂを出たＤＳＰ排水は、延長管部６Ｃ内を流下し、排水口３６を出て、水槽Ｔ内へ入る。水槽に入った排水は必要により有機廃棄物を除去する措置を施した後に建築物の外に排出するとよい。 The DSP drainage that has exited the first horizontal main pipe portion 6B flows down in the extension pipe portion 6C, exits the drainage port 36, and enters the water tank T. The wastewater that enters the aquarium should be discharged out of the building after taking measures to remove organic waste if necessary.
次に図４に基づいて洗浄作業について説明する。以下の解説では、説明を簡単にするため、専ら洗浄作業を行うケースを説明する。
すなわち、図４のＳ−１のように、予め通常の排水モードを停止させる（制御装置４６から従管路付きポンプ４ｄへ停止信号を送る）ものとする。実際には、例えば中継槽内の堆積物及び排水を除去している間に新たな排水が投入される場合もあり得る。
Next, the cleaning operation will be described with reference to FIG. In the following explanation, in order to simplify the explanation, a case where cleaning work is performed exclusively will be explained.
That is, as in S-1 of FIG. 4, the normal drainage mode is stopped in advance (a stop signal is sent from the control device 46 to the pump 4d with the follower pipe). In practice, for example, new waste water may be introduced while removing deposits and waste water in the relay tank.
制御装置４６は、洗浄モードとして次の動作を行う。
図４のＳ−３のように、搬送ポンプ３４に制御信号を送り、中継槽１４内の堆積物及び排水を空槽になるまで排水する。
図４のＳ−４のように、空槽を検知したとき、すなわち水位が零になったときには、搬送ポンプを停止する。
図４のＳ−５のように、給水手段３８に対して給水信号を送り、洗浄水を中継槽１４内に注入し、貯水する。
図４のＳ−６のように、水位が所定量に達したときには、給水を停止する。
図４のＳ−７のように、搬送ポンプ３４に再び制御信号を送り、中継槽内の洗浄水を第１横主管部に対し一気に放水させる。
図４のＳ−８〜Ｓ−９のように、空槽を検知したとき、すなわち中継槽１４内の洗浄水が無くなったときには、搬送ポンプを停止する。
The control device 46 performs the following operation as the cleaning mode.
As shown in S-3 in FIG. 4, a control signal is sent to the transport pump 34 to drain the deposits and drainage in the relay tank 14 until they become empty tanks.
As shown in S-4 of FIG. 4, when the empty tank is detected, that is, when the water level becomes zero, the transport pump is stopped.
As shown in S-5 of FIG. 4, a water supply signal is sent to the water supply means 38, and the wash water is injected into the relay tank 14 and stored.
When the water level reaches a predetermined amount as in S-6 of FIG. 4, water supply is stopped.
As shown in S-7 in FIG. 4, the control signal is sent again to the transport pump 34, and the cleaning water in the relay tank is discharged to the first horizontal main pipe at a stretch.
As shown in S-8 to S-9 in FIG. 4, when the empty tank is detected, that is, when the washing water in the relay tank 14 is exhausted, the transport pump is stopped.
洗浄モードが完了したら、図４のＳ−１０のように通常の排水モードに復帰する。制御装置４６は、洗浄水を貯水しかつ放水する工程を予め定められた回数繰り返すように構成するとよい。作業を繰り返すことで第１横主管部６Ｂ内の堆積物を全て流すためである。その繰返し回数ｎは、中空槽の容量と第１横主管部の長さとに応じて予め設計者が決め、制御装置に記憶させ、制御条件として取り込むようにするとよい（Ｓ−２）。上記の洗浄作業は一日に少なくとも一度行うことが望ましい。一日程度の作業スパンであれば堆積物が管壁内面に固着しないことが一般的だからである。 When the cleaning mode is completed, the normal drainage mode is restored as shown in S-10 of FIG. The control device 46 may be configured to repeat the process of storing and discharging the cleaning water a predetermined number of times. This is because all the deposits in the first horizontal main pipe portion 6B are made to flow by repeating the operation. The number of repetitions n may be determined in advance by the designer according to the capacity of the hollow tank and the length of the first horizontal main pipe portion, stored in the control device, and taken in as a control condition (S-2). It is desirable to perform the above-described cleaning operation at least once a day. This is because it is common that the deposit does not adhere to the inner surface of the pipe wall if the working span is about one day.
以下、本発明の他の実施形態を説明する。これらの説明において第１実施形態と同じ構成については同一の符号を付することで解説を省略する。 Hereinafter, other embodiments of the present invention will be described. In these descriptions, the same components as those in the first embodiment are denoted by the same reference numerals and the description thereof is omitted.
図５は、本発明の第２の実施形態に係る排水搬送システムを示している。 FIG. 5 shows a drainage transport system according to the second embodiment of the present invention.
このシステムでは、システム全体の管路系を第１管区Ａ１と第２管区Ａ２とに分けて、第１管区Ａ１では、第１実施形態のディスポーザから第１横主管部に至る流路及び関連設備の構成をそのまま適用し、第２管区Ａ２では、その構成のうち上流側通気口を省略している。第１管区の搬送ポンプの下流で通気口を設けると排水が漏出する可能性があるからである。 In this system, the pipeline system of the entire system is divided into a first division A 1 and a second division A 2, and in the first division A 1 , a flow path from the disposer of the first embodiment to the first horizontal main pipe section. and related equipment configuration is directly applied, in the second District a 2, it is omitted upstream vent of its configuration. This is because drainage may leak if a vent is provided downstream of the transport pump in the first section.
ここで第２管区の縦主管部を第２縦主管部６Ａ’と、また第２管区の横主管部を第２横主管部６Ｂ’と呼ぶものとする。第２管区の第２縦主管部６Ａ’は、第１横主管部６Ｂの下流側端部に連結させている。図面では省略しているが、同様に第３管区以降の構成も設けることができる。 Here, the vertical main pipe portion of the second division is called a second vertical main pipe portion 6A ', and the horizontal main pipe portion of the second division is called a second horizontal main pipe portion 6B'. The second vertical main pipe portion 6A 'of the second section is connected to the downstream end of the first horizontal main pipe portion 6B. Although omitted in the drawings, the third and subsequent regions can be similarly provided.
本実施形態の構成によれば、複数の配管上の障害物に応じて横主管部６Ｂ、６Ｂ’…を設けることができ、建築物での配管の自由度が向上する。また複数の配管上の障害物Ｏを迂回するために縦主管部及び横主管部を幾つ設けても、各管区毎に管区内の堆積物を除去するのに必要な搬送圧力をＤＳＰ排水に加えれば足りる。縦主管部の下端部である中継槽に下流側通気口を形成したからである。 According to the structure of this embodiment, horizontal main pipe part 6B, 6B '... can be provided according to the obstruction on several piping, and the freedom degree of piping in a building improves. Also, no matter how many vertical main pipes and horizontal main pipes are provided to bypass obstacles O on multiple pipes, the transport pressure necessary to remove the sediment in each pipe can be added to the DSP drainage. It's enough. This is because the downstream vent is formed in the relay tank which is the lower end of the vertical main pipe.
図６は、本発明の第３の実施形態に係る排水搬送システムを示す。この実施形態は第１の実施形態に係るシステムの要部（中継槽及びその周囲）の変形例であり、一つの中継槽に、同じ第１横主管部６Ｂに連続する複数（図示例では２つ）の流出口２８を設ける。一つの搬送ポンプ３４が正常動作しない場合に待機中の他の搬送ポンプ３４での送水に切替えたり、或いはＤＳＰ排水の流入量が過剰になったときに複数のポンプを同時運転させるためである。 FIG. 6 shows a drainage transport system according to a third embodiment of the present invention. This embodiment is a modification of the main part (the relay tank and its surroundings) of the system according to the first embodiment, and a plurality of (two in the illustrated example) are connected to the same first horizontal main pipe section 6B in one relay tank. Provided). This is because when one transport pump 34 does not operate normally, the pump is switched to water feeding by another transport pump 34 that is on standby, or a plurality of pumps are operated simultaneously when the amount of inflow of DSP wastewater becomes excessive.
上記流出口２８は、それぞれ搬送ポンプ３４を有する複数の並列管４８に接続し、第１横主管部６Bの上流側で合流する。以下に本実施形態の具体的な運用方法を説明する。 The outlet 28 is connected to a plurality of parallel pipes 48 each having a transport pump 34, and merges on the upstream side of the first horizontal main pipe portion 6B. A specific operation method of the present embodiment will be described below.
（１）中継槽内の水位が高水位（ＨＷＬ）で停止する標準的な運転パターン下に於いて、一つの搬送ポンプ３４を起動した後、一定時間経過してもフロートスイッチＦ１の接点が解除されないとき、すなわち水位が低下しないときには、排水不良と見倣して、他の搬送ポンプに運転を切替える。或いは突発的な流入量で搬送ポンプ３４の能力が不足していると見倣して、待機中のポンプを同時に運転させる。但し、先発の搬送ポンプを継続して運転できるのは過負荷運転などの異常な状態が無い場合とする。 (1) Under the standard operation pattern in which the water level in the relay tank stops at a high water level (HWL), the contact of the float switch F1 is released even after a certain time has elapsed after starting one transfer pump 34 When the operation is not performed, that is, when the water level does not decrease, the operation is switched to another transport pump, assuming that the drainage is defective. Alternatively, it is assumed that the capacity of the transport pump 34 is insufficient due to a sudden inflow amount, and the pumps on standby are operated simultaneously. However, the first transfer pump can be operated continuously when there is no abnormal state such as overload operation.
（２）中継槽底部の堆積物の完全排出を行う為に定期的に低水位（ＬＷＬ）を検知するフロートスイッチＦ２の検知を無視し、搬送ポンプ３４が空気を吸い込むまで運転させる。尚この運転動作はタイマーで行うのとする。 (2) In order to completely discharge the sediment at the bottom of the relay tank, the detection of the float switch F2 that periodically detects the low water level (LWL) is ignored, and the operation is continued until the transport pump 34 sucks air. This driving operation is performed by a timer.
（３）一方の搬送ポンプ３４が過負荷運転状態となった場合、損傷を未然に防止させるため電気的な保護装置を備えるのが一般的であるが、この保護装置が動作した時、自動的にもう一方の待機中の搬送ポンプ３４に運転を切替える。切替運転後、搬送ポンプはＬＷＬで自動停止し、水位上昇し、ＨＷＬに達した時、保護装置の動作で停止した搬送ポンプを運転させる再起動回路を備え、この運転状態を数回繰り返した後、異常が継続する場合、異常運転警報を発報する。一過性の過負荷であれば、再起動で解除できることもある。 (3) When one of the transport pumps 34 is overloaded, it is common to provide an electrical protection device to prevent damage, but when this protection device operates, Then, the operation is switched to the other transport pump 34 in standby. After switching operation, the conveyance pump automatically stops at LWL, and when the water level rises and reaches HWL, it is equipped with a restart circuit that operates the conveyance pump stopped by the operation of the protective device, and after repeating this operation state several times If the abnormality continues, an abnormal operation warning is issued. If it is a transient overload, it may be released by restarting.
