Description

本考案は、歯科用チェアユニットからの排液を、バキュームエアを用いて吸引して移送した後にエアから分離する排水分離器に係り、特に排水分離器と接続し、屋内から屋外へ配管する排水配管に係わる分離器の排水機能の改善に関するものである。  The present invention relates to a drain separator that separates the drainage liquid from the dental chair unit from the air after being sucked and transferred using vacuum air, and in particular, drainage that is connected to the drain separator and piped indoors to outdoors. It relates to the improvement of the drainage function of the separator related to piping.

歯科診療室に生じる排液は、切削歯牙含有液、口腔内分泌液と洗浄水からなる。図4に示すように、歯科チェアユニット10によって、加圧空気c、給水dを供給して口腔内を洗浄し、その洗浄排液aをスピットン10bに捨て、またバキュームシリンジ10aのエア弁11を開操作して吸気し、口腔内の排液aを吸い上げ、バキュームエアbによって、排水分離器13に搬送、集水するものである。該排水分離器において、付設のバキュームエア配管の電磁開閉弁14を閉操作した後、集水排液を屋外排水管12に排出する。ここに、二重実線は排液ないし排水管、破線は吸気ないしバキュームエア管、二重破線は加圧空気ないし加圧空気配管、実線は給水を、また破線矢印はバキュームエアの吸気方向、二重破線矢印は加圧空気の加圧方向を、さらに二重実線と破線の合併線ないしa+bは搬送用バキュームエアと排液との混合流体またはその混合配管を、a+cは加圧空気によって移動する排水の状態を、それぞれは示す。  The drainage generated in the dental clinic consists of a cutting tooth-containing liquid, an oral endocrine liquid and washing water. As shown in FIG. 4, the dental chair unit 10 supplies pressurized air c and water supply d to clean the inside of the oral cavity, discards the cleaning drainage liquid a into the spitons 10b, and sets the air valve 11 of the vacuum syringe 10a. It opens and inhales, sucks up the drainage liquid a in the oral cavity, and conveys and collects water by the vacuum air b. In the wastewater separator, after the electromagnetic on-off valve 14 of the attached vacuum air pipe is closed, the collected water drainage is discharged to the outdoor drainage pipe 12. Here, the double solid line is the drainage or drainage pipe, the broken line is the intake or vacuum air pipe, the double dashed line is the pressurized air or pressurized air piping, the solid line is the water supply, the dashed arrow is the intake direction of the vacuum air, Double broken arrows indicate the direction of pressurization of pressurized air, double solid and dashed merged lines, or a + b is a mixed fluid of conveying vacuum air and drainage or a mixed piping thereof, and a + c is moved by pressurized air. Each indicates the state of drainage.

屋外排水管12は通常、流下するに充分な自然勾配を持たせた配管施工によって円滑な排液排出を行うが、配管が逆勾配であると、排水管内に排液滞留が生じるので、順勾配になるように、埋設配管が出来ない場所では床上に配管をむき出しにして施工せざるを得ない。その際、配管施工区域の上側に山形傾斜路を設け、あるいは二重床に工作して排水管を隠蔽し、歩行障害が生じることのないような改造床を特設する。歩行に配慮した改造床を設けても、診療室に来る患者には、床面や傾斜面に乗り移る際に生じる僅かな段差や傾斜路に躓くことがある。特に診察室を雑居ビルに開設する場合しばしば、歯科用チェアユニットのための諸配管は後施工になり、雑居ビルの建築構造上、床下に排水管全てを収納できないので、特に排水管のために基準床面上に改造床を上乗せして設けざるを得ない。  The outdoor drain pipe 12 normally drains smoothly by piping construction with a natural gradient sufficient to flow down. However, if the pipe has a reverse slope, drainage stays in the drain pipe. As such, in places where buried piping is not possible, the piping must be exposed on the floor. At that time, a mountain-shaped ramp will be provided above the piping construction area, or a double floor will be constructed to conceal the drainage pipe, and a modified floor will be provided that will not cause gait disturbance. Even if a remodeled floor is provided in consideration of walking, patients who come to the doctor's office may crawl on slight steps or ramps that occur when they change to the floor or slope. Especially when opening an examination room in a miscellaneous building, the piping for the dental chair unit is often post-installed, and because of the architectural structure of the miscellaneous building, all drainage pipes cannot be stored under the floor. There is no choice but to install a modified floor on the reference floor.

図5に示すように、排水分離器13に排水タンク3を付設し、加圧空気cにより逆勾配排水管12の滞留排水を加圧することにより、順勾配配管がなされている屋外まで排除することもできる。ここに、5はフロート、6は排水受入管、8は水位感知センサ、9は電気配線、そしてL2は排水操作を始める上位水位を示す。なお、室内が順勾配配管になっている場合に使用可能とする市販の排水分離器(約220φ×300H、槽底設置高約280、排液流入VP管25φ、排水出口ホース38φ、単位mm(型番H2−14、(株)東京技研製))がある。この市販分離器は、約3.5リットルの槽容量があり、平均1日3回起動して、自動排水が行えるようになっている。  As shown in FIG. 5, the drainage tank 13 is attached to the drainage separator 13, and the staying drainage of the reverse gradient drainage pipe 12 is pressurized by the pressurized air c, so that it is excluded to the outdoors where the forward gradient piping is made. You can also. Here, 5 is a float, 6 is a drain receiving pipe, 8 is a water level detection sensor, 9 is an electrical wiring, and L2 is an upper water level at which drainage operation is started. It should be noted that a commercially available drainage separator (about 220φ × 300H, tank bottom installation height of about 280, drainage inflow VP pipe 25φ, drainage outlet hose 38φ, unit mm ( Model No. H2-14, manufactured by Tokyo Giken Co., Ltd.). This commercial separator has a tank capacity of about 3.5 liters and is activated three times a day on average to enable automatic drainage.

一般に排水分離器は、バキュームフロア装置に隣接する機械室に設置される。広さに余裕がないテナント用居室では、充分な医療器械を配置できない場合がある。また歯科診療時に用いる加圧空気は、瞬間的に用い、その使用量は数ミリ口径のノズルから吐出される僅かの流量である。一方、加圧空気によって排水分離器の排水排除を行う前記例では、排水用ホース38φに供給する空気量を必要とする。しかもバキュームシリンジを用いる治療中に加圧空気排水の処理動作が生じると、吸気治療や加圧空気治療に悪影響を及ぼすことが懸念される。しかし、この点に対応して加圧空気排水主体で空気源容量を決めるのは、本末転倒の嫌いがある。
なお、水位検知、制御スイッチ18などの水位制御機構は従来技術を用い、本考案の技術課題ではないので、詳細は本件記載内容から省く。
Generally, the waste water separator is installed in a machine room adjacent to the vacuum floor device. In tenant rooms that are not large enough, there may be cases where sufficient medical equipment cannot be placed. Moreover, the pressurized air used at the time of dental treatment is used instantaneously, and the amount used is a slight flow rate discharged from a nozzle having a diameter of several millimeters. On the other hand, in the example in which the drainage of the drainage separator is removed by pressurized air, the amount of air supplied to the drainage hose 38φ is required. In addition, if a pressurized air drain treatment operation occurs during the treatment using the vacuum syringe, there is a concern that the intake air treatment or the pressurized air treatment may be adversely affected. However, to determine the air source capacity mainly by pressurized air drainage corresponding to this point, there is a dislike of falling over at the end.
Since the water level control mechanism such as the water level detection and control switch 18 uses conventional technology and is not a technical problem of the present invention, the details are omitted from the description in this case.

解決しようとする問題点は、排水分離器でバキュームエアから分離した排液を集水して溜めた排水を、屋内に敷設された逆勾配配管の手前で接続配管するようになった場合に、順勾配で屋外排出できる排水管まで排水処理できないかという点、である。  The problem to be solved is that when the drainage separated from the vacuum air by the drainage separator is collected and collected, the drainage pipe is connected before the reverse gradient pipe installed indoors. It is the point that drainage treatment can be performed up to a drain pipe that can be discharged outdoors with a forward gradient.

本考案は、排水貯留部に水中ポンプを内設し、その吐出管を屋外排水用の出口配管に挿設し、その出口配管には逆止弁および/または水中ポンプ始動と同時に開作動操作する電磁開閉弁を付設し、かつ貯留排水の水位制御機構に連動するポンプと、バキュームエア用電磁開閉弁とベント機構と、そのベントの開作動と連係するポンプ作動操作を行う制御手段(18)を、排水分離器または排水分離器に付設し、分離器の排水貯留と排出制御機構を分離、特設する排水タンクに設けたことを特徴とする。  In the present invention, a submersible pump is installed in the drainage reservoir, its discharge pipe is inserted into an outlet pipe for outdoor drainage, and the outlet pipe is opened at the same time as the check valve and / or submersible pump is started. A pump having an electromagnetic on-off valve and interlocking with a water level control mechanism for stored wastewater, a vacuum air electromagnetic on-off valve and a vent mechanism, and a control means (18) for performing a pump operation in conjunction with the opening operation of the vent. The drainage separator or the drainage separator is provided, and the drainage storage and discharge control mechanism of the separator is separated and provided in a specially provided drainage tank.

本考案は、歯科排液を排水分離器へ集水した後に、分離器に直接または付設する排水タンクに排水操作を分担させて間接的に、内設する水中ポンプを起動する。予め生ずる排水抵抗に対応して選ぶ充分な実揚程を有するポンプの加圧水によって、逆勾配状態の配管内滞留水を強制排除できる。水圧による排除力は、排水貯留部のベント機構を作動させることにより、ポンプのサクション側圧力調整が加圧力をより有効になるように保持する。
排液とエアの分離機能と貯留排水の排出機能を、排水分離器に排水タンクを付設して分担できるので、エア分離と排水排出を同時に行えるようにした。
ポンプ稼働のタイミングによっては配管内滞留水を残留させることがあるが、出口配管に設ける逆止弁と電磁開閉弁の作用によって、分離器や排水タンクの排水貯留部に逆流する現象はなく、次に行う追加の排水処理によって、順次、排水排除が確実に進む。
In the present invention, after collecting the dental drainage into the drainage separator, the drainage operation is shared directly or indirectly with the drainage tank attached to the separator, or the submersible pump installed inside is activated. Residual water in the pipe in the reverse gradient state can be forcibly removed by the pressurized water of the pump having a sufficient actual head selected corresponding to the drainage resistance generated in advance. Exclusion force by water pressure keeps the suction side pressure adjustment of the pump more effective by operating the vent mechanism of the drainage reservoir.
Since the drainage and air separation function and the stored drainage discharge function can be shared by attaching a drainage tank to the drainage separator, air separation and drainage discharge can be performed simultaneously.
Depending on the timing of the pump operation, the accumulated water in the pipe may remain, but there is no phenomenon of backflow to the drainage storage part of the separator or drainage tank due to the action of the check valve and electromagnetic on-off valve provided in the outlet pipe. As a result, additional wastewater treatment will be carried out in order to ensure the elimination of wastewater.

逆勾配などの排水障害域が生ずる屋内排水管内滞留水を排除する目的を、排水分離器や付設する排水タンクに配設する水中ポンプ、ベント機構、排水配管敷設の逆止弁、電磁開閉弁、連係する制御手段を操作して、生じるポンプ発生水圧により達成、実施した。  For the purpose of eliminating stagnant water in indoor drain pipes where drainage failure areas such as reverse gradient occur, submersible pumps installed in drain separators and attached drain tanks, vent mechanisms, check valves for drain pipe laying, electromagnetic on-off valves, Achieved and implemented by operating the associated control means and the resulting pumped water pressure.

図1は、本考案の、歯科排水用排水分離器付設の排水タンクを説明するもので、(A)は水中ポンプを装着した排水タンクの部分側断面を含む側面図、(B)はその制御手順を示す流れ図、図2は、同じくその排水分離器を説明するもので、(A)水中ポンプを装着した排水分離器の側断面を含む部分側面図、(B)はそのベント弁を示す部分側面図、そして図3は、同じく排水分離器付設のベント作用を説明するもので、その作動手順を示す流れ図である。
図1(A)に示すように、排水分離器13が集水した排液aを、図5に示す電磁開閉弁を付設する排水受入管6を通って排水タンク3に導入する。該排水タンクには、タンク天井から垂設する管状体と、該管状体内部に挿通する細管と、該細管をガイドにタンク内排水量によって上下するフロート5と、該フロートが浮上して上位水位L2に達すると近接スイッチがON作動する水位感知センサ8を前記管状体内部に装着すると共に、排水障害域を含む機外配管の排水抵抗以上の実揚程を有する水中ポンプ1を、排水タンク3の底部に設置して構成する。該水中ポンプの電気配線9は、前記細管の内部を経てタンク外部に通じ、水位や弁操作を処理する制御機構7内部の、ここに図示しないスイッチ回路を含む制御回路に接続する。同様に水位感知センサ8の電気配線は、前記制御回路に接続している。ポンプ起動によって排水量が低減し、フロート5が下限位置になると、前記細管に仕組む下限水位L1の、ここに図示しない感知センサが作動して、一連の排水停止操作が処理される。ここに電気配線9は、信号線、ポンプ動力を供給する電気線を含み、17はポンプ稼働のタンク内に、水位減少に見合う空気Bを供給するためのベント口である。
水中ポンプ1の吐出管は、タンク1側壁に設ける配管口座を介して、屋外排出用の排水管12に連通、配管され、該排水管には逆止弁2を配設する。該逆止弁に代えて電磁開閉弁4のみを配管してもよく、あるいは図示のように、逆止弁と電磁開閉弁を並設して設けてもよい。ここに排水タンク3底部の突起物は、プラグしたドレン配管口座を示す。
FIG. 1 illustrates a drainage tank with a drainage separator for dental drainage according to the present invention. (A) is a side view including a partial side section of a drainage tank equipped with a submersible pump, and (B) is a control thereof. FIG. 2 is a flow chart showing the procedure, and FIG. 2 also explains the waste water separator, (A) a partial side view including a side cross section of a waste water separator equipped with a submersible pump, and (B) a portion showing the vent valve. A side view and FIG. 3 are the same flow charts showing the operating procedure for explaining the venting action with the drain separator.
As shown in FIG. 1A, the drainage liquid a collected by the drain separator 13 is introduced into the drain tank 3 through the drain receiving pipe 6 provided with the electromagnetic on-off valve shown in FIG. The drainage tank includes a tubular body suspended from the tank ceiling, a thin tube inserted into the tubular body, a float 5 that moves up and down according to the amount of drainage in the tank using the thin tube as a guide, and the float that rises to the upper water level L2. When the water level detection sensor 8 whose proximity switch is turned on is installed inside the tubular body, the submersible pump 1 having an actual lifting height greater than the drainage resistance of the external piping including the drainage fault zone is connected to the bottom of the drainage tank 3. Install and configure. The electrical wiring 9 of the submersible pump is connected to a control circuit including a switch circuit (not shown) inside the control mechanism 7 for processing the water level and valve operation through the inside of the narrow tube to the outside of the tank. Similarly, the electrical wiring of the water level detection sensor 8 is connected to the control circuit. When the amount of drainage is reduced by starting the pump and the float 5 reaches the lower limit position, a detection sensor (not shown) at the lower limit water level L1 that works on the narrow tube is activated to process a series of drainage stop operations. Here, the electrical wiring 9 includes a signal line and an electrical line for supplying pump power, and 17 is a vent port for supplying air B suitable for the decrease in the water level into the pump-operated tank.
The discharge pipe of the submersible pump 1 communicates and is connected to a drain pipe 12 for outdoor discharge via a pipe account provided on the side wall of the tank 1, and a check valve 2 is provided in the drain pipe. Instead of the check valve, only the electromagnetic on-off valve 4 may be piped, or as shown, the check valve and the electromagnetic on-off valve may be provided in parallel. Here, the protrusion on the bottom of the drainage tank 3 indicates a plugged drain piping account.

このように排水分離器13に付設する排水タンク3を、前記弁類を付設する排水管12とともに配設したので、排水分離器13は排液aの集水と、エアbと排液aの分離処理を合わせて行いながら、分離器のバキュームエア回収操作とは無関係に、排水タンク3に分離、移送した排液aをタンク3の外部へ排水処理する。その排水処理はポンプ1の吐出圧を利用した加圧操作によるので、排水管12の排水障害域滞留水を排水障害のない所まで容易に排除できる。その上、水中ポンプ1が停止しても、逆勾配の配管内に残留する滞留水は逆止弁2または電磁開閉弁4の存在によって、排出分離器13や排水タンク3に還流しない。  Thus, since the drainage tank 3 attached to the drainage separator 13 is disposed together with the drainage pipe 12 to which the valves are attached, the drainage separator 13 collects the drainage a, the air b and the drainage a. The waste liquid a separated and transferred to the drainage tank 3 is drained to the outside of the tank 3 regardless of the vacuum air recovery operation of the separator while performing the separation process together. Since the wastewater treatment is performed by a pressurizing operation using the discharge pressure of the pump 1, the accumulated water in the drainage fault area of the drainage pipe 12 can be easily removed to a place where there is no drainage fault. In addition, even if the submersible pump 1 is stopped, the remaining water remaining in the reverse-graded pipe does not return to the discharge separator 13 or the drainage tank 3 due to the presence of the check valve 2 or the electromagnetic on-off valve 4.

図2に示すのは、排水タンク3を付設せず、排水分離器13に直接、水中ポンプ1を内設して、排水障害域を形成する排水管12の滞留水を排除する実施例2を示す。しかし、排液aとエアbの分離操作と排液排出操作とを、同時に行わないようにした制御手段18を付帯させ、かつ図1(A)に示した排水タンク3の構成にならって、電気配線や出口配管周りの設備を該排水分離器に加えることによって実施可能になる。前記分離操作と排液排出操作を同時に起こさないために、分離器13頂部にベント機構15を設ける。該ベント機構内側には通過空気発生音に対処する防音処理を行う。  FIG. 2 shows a second embodiment in which the submersible pump 1 is installed directly in the drain separator 13 without the drain tank 3 and the accumulated water in the drain pipe 12 forming the drainage fault zone is excluded. Show. However, according to the configuration of the drainage tank 3 shown in FIG. 1 (A), the control means 18 that does not simultaneously perform the separation operation of the drainage liquid a and the air b and the drainage discharge operation is attached. It becomes feasible by adding equipment around the electrical wiring and outlet piping to the drainage separator. A vent mechanism 15 is provided at the top of the separator 13 so as not to cause the separation operation and the drainage operation simultaneously. A soundproofing process is performed on the inside of the vent mechanism to cope with the sound generated by the passing air.

同図(A)に示すベント機構に係る実施例3は、バキュームエアbの吸引作動時にタンク内の負圧発生に連動してベント口を閉鎖するベント機構を示す。該機構は、回動弁体16を嵌設して、弁が円弧実線矢印のように動いてベント口を閉鎖させるものである。前記エアbの吸引が止めば、前記回動弁体付設の復帰バネが作用して閉鎖状ベント口が開状態になる。
バキュームエアbの吸引が正常吸引圧まで復帰する際の、作動タイムラグを短縮するために、バキュームエア管とベント機構のベント配管とを接続するようにした、三点鎖線で図示する吸引管を特設しても良い。この吸引管がバキュームエア用電磁開閉弁14の開作動とほぼ同時に回動弁体16に対し吸引圧を直接、働かせる作用を生じる。その結果、排水分離器13の内圧を早期に負圧状態に近付け、前記液・エア分離操作を早める。水中ポンプ1の稼働時にはベント口が開状態になって、その排水吐出量能力にマイナス効果に働く負荷増加原因を除くことが出来る。
A third embodiment related to the vent mechanism shown in FIG. 3A shows a vent mechanism that closes the vent port in conjunction with the generation of a negative pressure in the tank during the suction operation of the vacuum air b. In this mechanism, the rotary valve body 16 is fitted and the valve moves as indicated by a solid arc arrow to close the vent port. When the suction of the air b is stopped, the return spring provided with the rotating valve body acts to open the closed vent port.
In order to reduce the operating time lag when the suction of the vacuum air b returns to the normal suction pressure, a suction pipe illustrated with a three-dot chain line is provided to connect the vacuum air pipe and the vent piping of the vent mechanism You may do it. This suction pipe causes the suction pressure to act directly on the rotary valve body 16 almost simultaneously with the opening operation of the vacuum air electromagnetic on-off valve 14. As a result, the internal pressure of the waste water separator 13 is quickly brought close to the negative pressure state, and the liquid / air separation operation is accelerated. When the submersible pump 1 is in operation, the vent port is opened, and the cause of the load increase that has a negative effect on the drainage capacity can be eliminated.

同図(B)に示すベント機構に係る実施例4は、ベント機構15において、前記回動弁体に代えてベント口座17を常時開状態にし、制御時を閉状態に代えるベント用電磁開閉弁19を配管して構成する。バキュームエアbの吸引作動時に、バキュームエア用電磁開閉弁14の開作動に連動してベント用電磁開閉弁19を閉作動させるものである。  FIG. 5B shows a vent mechanism according to a fourth embodiment. In the vent mechanism 15, the vent account 17 is always opened instead of the rotating valve body, and the vent electromagnetic open / close valve is switched to the closed state. 19 is constructed by piping. During the suction operation of the vacuum air b, the venting electromagnetic on-off valve 19 is closed in conjunction with the opening operation of the vacuum air electromagnetic on-off valve 14.

排水タンクを付設しない、本考案の排水分離器13においては、集水容量として上位水位L2の上方空間は、変動集水量を見込んだ低めの位置に設定し、集水による貯液受け入れ分を見込み、早めにポンプ起動ができるようにする。
すなわち制御手段18は、図3に示すように、前記した図1(B)に示す流れ図の、ステージS2と同S3の間に、バキュームエア弁14の閉(S6)に連動してベント弁16ないしベント用電磁開閉弁19(S7)を、さらにステージS4と同S5の間に、該ベント弁16ないし該ベント用電磁開閉弁(S8)に連動して、バキュームエア弁14閉作動の待機OK状態(S9)を、それぞれ挿入する制御作業を行い、排液排出操作中であっても、液とエアの分離操作を優先し、分離操作が始まれば水中ポンプの起動停止や弁開閉操作などの制御スイッチを含む制御機構7または18を構成する。
In the drainage separator 13 of the present invention, which does not have a drainage tank, the space above the upper water level L2 is set to a lower position to allow for a variable water collection volume as the water collection capacity, and the amount of liquid storage received by the water collection is expected. , So that the pump can be started early.
That is, as shown in FIG. 3, the control means 18 is connected to the vent valve 16 in conjunction with the closing of the vacuum air valve 14 (S6) between the stages S2 and S3 in the flowchart shown in FIG. Further, the solenoid valve 19 for venting 19 (S7) is further connected between the stage S4 and S5 in conjunction with the vent valve 16 or the solenoid valve for venting (S8) to wait for the vacuum air valve 14 to be closed. Control operation to insert each state (S9), and even during the drainage operation, priority is given to the separation operation of liquid and air, and if the separation operation starts, the submersible pump start and stop, valve opening and closing operation, etc. A control mechanism 7 or 18 including a control switch is configured.

排水タンク3を付設しない、排水分離器13の単独運転操作のみでも、分離と排水の操作機能を交互に働かせて、排水障害域の滞留水排除をできるようにしたので、水中ポンプ1が例え短時間運転で、排液吐出を中断するようなことがあっても、一旦、分離器外へ吐出した量は、逆止弁2や電磁開閉弁4の設置機能によって排水分離器13に還流することがない。しかも分離器外へ排出した後は、順次、排除する排水量によって、屋外に移送できるという効果がある。 前記分離と排水の両操作をそれぞれ単独操作できる分離器に付設する排水タンク方式にあっては、より円滑な両操作を可能にする。  Even with a single operation of the drain separator 13 without the drain tank 3, the operation function of separation and drainage can be operated alternately so that the accumulated water in the drainage fault area can be eliminated. Even if the drainage discharge is interrupted by the time operation, the amount discharged to the outside of the separator is once returned to the drainage separator 13 by the installation function of the check valve 2 and the electromagnetic on-off valve 4. There is no. In addition, after discharging to the outside of the separator, there is an effect that it can be transferred to the outside depending on the amount of drainage to be sequentially removed. In the drainage tank system attached to the separator capable of operating both the separation and drainage individually, both smoother operations are possible.

ポンプを排水貯留部に内設する構成の、排水分離器13または排水タンク3のいずれを設置する場合においても、水中ポンプ1の動作は、図1(B)に示すように、排液aが注入され(S1)、順次、フロート5が浮上して排液の水位センサ8が上位水位L2に達したことを感知すると(S2)、水中ポンプ1がON作動する(S3)。ポンプ運転の結果、排液を排水貯留部外へ吐出して槽貯留量が減少し、随時、フロート5を下降させる。該フロート5位置が下位水位L1に達したことが感知されると(S4)、ポンプ1は起動停止する(S5)。この工程流れは、ステージS5からS2に戻り、またS5に続く循環処理を、排液処理を停止させるまで繰り返す。  In the case where either the drain separator 13 or the drain tank 3 having a configuration in which the pump is installed in the drainage storage section is installed, the operation of the submersible pump 1 is performed as shown in FIG. Injected (S1), and when the float 5 rises and the drained water level sensor 8 senses that it has reached the upper water level L2 (S2), the submersible pump 1 is turned on (S3). As a result of the pump operation, the drainage is discharged out of the drainage storage part, the tank storage amount decreases, and the float 5 is lowered as needed. When it is sensed that the float 5 position has reached the lower water level L1 (S4), the pump 1 is started and stopped (S5). This process flow returns from the stage S5 to S2, and the circulation process following S5 is repeated until the drainage process is stopped.

ここに、設置する水中ポンプ1は、排水障害域の逆勾配程度が少なく、水頭抵抗が200mm以下ならば、家庭の浴室に汲み出しに用いる水中ポンプで差し支えない。最大の位置水頭抵抗は、出入口扉を配管がまたぐ場合に滞留水が乗り越えられることと推定すれば、実揚程3mの水中ポンプで充分、実用できる。前記した市販の排水分離器を転用する場合には、電気系統の改造を含む僅かな仕様変更で本考案が実施できる。あるいは付設用の排水タンク3には、VP管やダクト用管など太い管径の配管材を加工して形成できる。ポンプの吐出管およびタンク外の屋内排水管は、ポンプ揚程に応じて内圧に耐えられるものなら、小径のVP管や軟質ビニールホースが使える。またこれら資材で形成する排水分離器13や排水タンク3の側断面形状は、直径300mm以内に収まる。  Here, the submersible pump 1 to be installed may be a submersible pump used for pumping into a household bathroom as long as the reverse gradient of the drainage failure area is small and the head resistance is 200 mm or less. Assuming that the maximum position head resistance can get over the accumulated water when the piping crosses the doorway, a submersible pump with an actual head of 3 m can be used sufficiently. When diverting the above-mentioned commercially available wastewater separator, the present invention can be implemented with slight specification changes including modification of the electrical system. Alternatively, the auxiliary drainage tank 3 can be formed by processing a pipe material having a large pipe diameter such as a VP pipe or a duct pipe. If the pump discharge pipe and the indoor drain pipe outside the tank can withstand the internal pressure according to the pump head, a small-diameter VP pipe or a soft vinyl hose can be used. Moreover, the side cross-sectional shape of the waste water separator 13 and the waste water tank 3 formed with these materials falls within 300 mm in diameter.

このようにして付設タンク型を含む、水中ポンプ1を内設する排水分離器13を構成することによって、歯科チェアユニット10から不定期に発生する歯科排液を集水、貯留し、この貯留操作とは独立して排水排出操作を水中ポンプの吐出圧操作によって効果的に排水処理できるという利点を得た。しかもその操作を実現するに当たって、既設排水管が順勾配であってそこに付設施工する新設排水管が接続できるのなら、その新設屋内排水管を予め自然勾配で布設しようと配慮することなく、すなわち排水勾配の順または逆状態を気に掛けることなく、排水配管を施工できるようになった。  In this way, by configuring the drainage separator 13 including the submersible pump 1 including the attached tank type, the dental drainage generated irregularly from the dental chair unit 10 is collected and stored, and this storing operation is performed. Independently, the drainage operation can be effectively performed by the discharge pressure operation of the submersible pump. Moreover, in realizing the operation, if the existing drainage pipe is forward-gradient and a new drainage pipe to be installed can be connected to it, without considering to install the new indoor drainage pipe with a natural slope in advance, that is, It is now possible to construct drainage pipes without worrying about the order of the drainage gradient or the reverse state.

本考案によれば、テナント用居室に歯科やその他の医療施設を設ける場合、そこに順勾配による自然流水処理が行えない排水障害区域が明らかに存在しても、テナントビルなどの居室内にバリアフリー化が達成できる排水処理手段を構築することができる。
従って交通が便な人口密集地において、歯科を含む医療関係者や治療を望む患者などが、医療器械を設置して行う医療業務、教育、デモンストレーション行為などを、従来は排水配管上に難点があって行えなかった活動を、利用し易い雑居ビル内でも開設できるようになり、活動の場を広くした。
According to the present invention, when a dental or other medical facility is provided in a tenant's room, even if there is a clear drainage area where natural running water treatment cannot be performed due to a forward slope, there is a barrier in the room such as a tenant building. Wastewater treatment means that can be made free can be constructed.
Therefore, in a densely populated area with convenient transportation, medical staff, including dentistry, and patients who wish to receive medical treatment, education, demonstration activities, etc., where medical instruments are installed, have traditionally been difficult on drainage piping. Activities that could not be done in the past can now be opened in easy-to-use multi-purpose buildings.
