First, the drainage device main body is disposed so that the lower surface of the flange portion 11 is in contact with the upper peripheral surface of the opening of the wash bowl. Further, the nut member 6 is inserted from below the drainage device main body, the female screw of the nut member 6 is screwed into the male screw of the drainage device main body, and the periphery of the opening is formed on the lower surface of the flange portion 11 of the drainage device main body and the nut member 6. The drainage device main body is attached and fixed to the sink S of the sink.
Further, the discharge port 13 of the drain port member 5 and the upstream end of the trap member 8 (the upper end of the first vertical pipe portion 8 a) are connected via the upstream connection pipe 9.
Further, the downstream end portion of the trap member 8 (the lower end of the third vertical pipe portion 8 e) and the drainage pipe under the floor are connected via the downstream connection pipe 10. Further, the strainer member 3 is mounted and placed in the drain port 12 of the drain port member 5 using the mounting piece 15, and the construction of the drain pipe of the sink is completed. In this piping work, the storage tank 2 is provided in the drainage pipe, so that the construction can be performed with the same procedure and trouble as the conventional drainage pipe.

上記のように配管された流し台を使用する場合、流し台を使用し、流し台の内部に排水が生じると、排水は排水口１２からストレーナー部材３を通過して排出口１３、上流側接続管９を通過し、第一垂直管部８ａ、第一屈曲部８ｂ、第二垂直管部８ｃ、第二屈曲部８ｄ、第三垂直管部８ｅの順にトラップ部材８内部を通過し、下流側接続管１０を介して床下の排水配管に排出される。また、このとき、封水部内部に封水が溜まることによって、床下の排水配管の下流にある下水側から臭気や害虫類が屋内に逆流してくることを防止する事ができる。また、ストレーナー部材３の捕集部１４では、当然ながら排水中の塵芥が濾過・捕集される。 When using a sink that has been piped as described above, if drainage occurs inside the sink, the drainage passes from the drainage port 12 through the strainer member 3 to the discharge port 13 and the upstream connecting pipe 9. Passes through the trap member 8 in the order of the first vertical pipe portion 8a, the first bent portion 8b, the second vertical pipe portion 8c, the second bent portion 8d, and the third vertical pipe portion 8e. It is discharged to the drainage pipe under the floor. In addition, at this time, since the sealed water accumulates inside the sealed water portion, it is possible to prevent odors and pests from flowing back indoors from the sewage side downstream of the drainage pipe under the floor. Moreover, in the collection part 14 of the strainer member 3, naturally the dust in waste water is filtered and collected.

更に、上記第一実施例の油水分離機構を備えた排水配管では、油水分離機構１として撥水加工を施したメッシュ体を備えなる。この油水分離機構１に、油分が混入した排水が接すると、排水中の水分は撥水加工によって反発し、メッシュ体の表面に排水の表面張力で球体が生じる。この時生じた球体がメッシュ体の開口より大きい為、排水中の水分はメッシュ体の開口を通過して貯留タンク２内に流れ込むことはできない。
一方、排水中の油分は撥水加工によっても反発することが無く、メッシュ体の表面に球体を作ることもないから、そのままメッシュ体の開口を通過し、貯留タンク２内に流れ込み捕集される。全ての排水が油水分離機構１のメッシュ体に触れるわけではないため、排水中から全ての油分を分離できるわけではないが、このようにして、排水中から部分的ながら選択的に油分を回収することができ、排水配管において、回収した油分の分だけ、油分による管詰まりの発生を減少させることができる。
また、貯留タンク２に油分が一定量貯留された場合、貯留タンク２を配管から分離し、内部の油分を回収した後、再度配管に接続して継続的に使用することができる。 Further, in the drainage pipe provided with the oil / water separation mechanism of the first embodiment, the oil / water separation mechanism 1 is provided with a mesh body subjected to water repellent finish. When the wastewater mixed with oil comes into contact with the oil / water separation mechanism 1, the water in the wastewater is repelled by the water repellent process, and a sphere is generated on the surface of the mesh body by the surface tension of the wastewater. Since the sphere generated at this time is larger than the opening of the mesh body, the water in the waste water cannot flow into the storage tank 2 through the opening of the mesh body.
On the other hand, the oil content in the drainage does not repel even by water repellent processing, and does not make a sphere on the surface of the mesh body, so it passes through the opening of the mesh body as it is, flows into the storage tank 2 and is collected. . Since not all drainage touches the mesh body of the oil / water separation mechanism 1, not all oil can be separated from the drainage, but in this way, the oil is partially and selectively recovered from the drainage. In the drainage piping, the occurrence of clogging of the pipe due to the oil can be reduced by the amount of the recovered oil.
When a certain amount of oil is stored in the storage tank 2, the storage tank 2 can be separated from the pipe and the internal oil can be collected, and then connected to the pipe again and used continuously.

On the other hand, the oil content in the wastewater does not repel even by water repellent processing, and does not make a sphere on the surface of the mesh body. Is sent to a septic tank or the like for purifying the oil, and decomposed and processed. Thus, since the oil content in the separated waste water is treated at any time, there is no need to periodically collect and process the oil content as in the storage tank 2 of the first embodiment, and an easy-to-use oil / water separation mechanism is provided. It can be a drainage pipe provided.

As is apparent from FIG. 5, in the drain port member 5 of the third embodiment, the drain port 13 is bent about 90 degrees laterally with respect to the drain port 12. The collection portion 14 of the strainer member 3 has a bottomed cylindrical shape and is provided with a plurality of small openings in the side surface direction. It flows toward the bent outlet 13. In other words, in this third embodiment, the oil / water separation mechanism 1 provided in the collecting section 14 is provided at the bent portion of the drainage pipe, and the oil / water separation mechanism 1 is provided facing the upstream side of the drainage. It will be.

更に、上記第三実施例の油水分離機構を備えた排水配管では、ストレーナー部材３の捕集部１４の中央部分に、油水分離機構１として撥水加工を施してなる。この油水分離機構１に、油分が混入した排水が接すると、排水中の水分は撥水加工によって反発し、メッシュ体の表面に排水の表面張力で球体が生じる。この時生じた球体がメッシュ体の開口より大きい為、排水中の水分はメッシュ体の開口を通過して貯留タンク２内に流れ込むことはできない。
一方、排水中の油分は撥水加工によっても反発することが無く、メッシュ体の表面に球体を作ることもないから、そのままメッシュ体の開口を通過し、貯留タンク２内に流れ込み捕集される。全ての排水が撥水加工を施された、油水分離機構１のメッシュ体に触れるわけではないため、排水中から全ての油分を分離できるわけではないが、このようにして、排水中から部分的ながら選択的に油分を回収することができ、排水配管において、回収した油分の分だけ、油分による管詰まりの発生を減少させることができる。また、貯留タンク２に油分が一定量貯留された場合、貯留タンク２ごとストレーナー部材３を排水口１２から取り出し、更に貯留タンク２を分離し、内部の油分を回収した後、再度ストレーナー部材３に取り付けて、ストレーナー部材３を排水口１２内部に再度配置することで、継続的に使用することができる。 Furthermore, in the drainage pipe provided with the oil / water separation mechanism of the third embodiment, a water repellent process is performed as the oil / water separation mechanism 1 on the central portion of the collection portion 14 of the strainer member 3. When the wastewater mixed with oil comes into contact with the oil / water separation mechanism 1, the water in the wastewater is repelled by the water repellent process, and a sphere is generated on the surface of the mesh body by the surface tension of the wastewater. Since the sphere generated at this time is larger than the opening of the mesh body, the water in the waste water cannot flow into the storage tank 2 through the opening of the mesh body.
On the other hand, the oil content in the drainage does not repel even by water repellent processing, and does not make a sphere on the surface of the mesh body, so it passes through the opening of the mesh body as it is, flows into the storage tank 2 and is collected. . Since not all the drainage touches the mesh body of the oil / water separation mechanism 1 which has been subjected to water repellent finish, not all oil can be separated from the drainage, but in this way, it is partially from the drainage. However, the oil can be selectively recovered, and the occurrence of tube clogging due to the oil can be reduced by the amount of the recovered oil in the drainage pipe. In addition, when a certain amount of oil is stored in the storage tank 2, the strainer member 3 is taken out from the drain port 12 together with the storage tank 2, further separated from the storage tank 2, and the internal oil content is recovered, and then again to the strainer member 3. It can be used continuously by attaching and arranging the strainer member 3 in the drain 12 again.

本発明の実施例は上記のようであるが、本発明は上記実施例に限定されるものでなく、特許請求の範囲に記載の範囲において適宜変更が可能である。

Similarly, the oil-water separation mechanism of the present invention can be used as appropriate for the drainage pipe under the floor.
Also, the oil / water separation mechanism of the present invention can be adopted for drainage equipment provided in the middle of the drainage pipe such as a grease trap. For example, in the case of a grease trap, the oil / water separation mechanism of the present invention can be used for piping upstream of the tank portion for oil / water separation of the grease trap (regardless of whether the grease trap casing is disposed inside or outside the casing). By separating the oil from the wastewater to some extent in advance and then performing full-fledged oil / water separation with the grease trap, the burden on the grease trap can be reduced.

また、上記実施例等で記載したように、本発明の排水配管には流し台のシンクＳや、洗面台の洗面ボウル、浴槽・浴室などの槽体も排水配管に含まれるものである。よって、図６に示したように、第三実施例に記載したストレーナー部材３から載架部片を省略し、代わりに脚部１６を設け、この脚部１６によってシンクＳなどの槽体内部にストレーナー部材３を配置するように構成しても良い。 Further, as described in the above-described embodiments, the drainage pipe of the present invention includes sinks S for sinks, wash bowls for washstands, and bath bodies such as bathtubs and bathrooms.

また、本発明の各実施例では、油水分離機構１は排水の流れに対して完全に対向する角度、正確には排水の流れに対し９０度の角度で設けられているが、例えば図８に示したように、反発された排水が下流に流れやすいように、下流に向けて５度乃至１０度程度の若干の勾配を設けて構成してもかまわない。 Further, in each embodiment of the present invention, the oil / water separation mechanism 1 is provided at an angle that completely faces the drainage flow, more precisely, an angle of 90 degrees with respect to the drainage flow. As shown, a slight gradient of about 5 to 10 degrees may be provided downstream so that the repelled drainage can easily flow downstream.

また、上記各実施例において、油水分離機構１のメッシュ体は、ステンレスなどのその形状を維持できる金属材の薄板に小さな開口（直径１．４ミリメートル程度）を規則的に複数設けてメッシュ体として構成してなるが、本発明はこれに限定されるものではなく、線条体を交差するようにして組み合わせた網目体からなるメッシュ体など、その表面に撥水加工を施すことで水が表面張力により球形状となったときに、通過できなくなる小さな開口を複数設けた構造であれば、どのようなメッシュ体を利用してもかまわない。 In each of the above embodiments, the mesh body of the oil / water separation mechanism 1 is formed by regularly providing a plurality of small openings (about 1.4 mm in diameter) on a thin metal plate that can maintain its shape such as stainless steel. However, the present invention is not limited to this, and the surface of the water can be obtained by subjecting the surface to water repellent treatment, such as a mesh body composed of mesh bodies that are combined so as to intersect the striatum. Any mesh body may be used as long as it has a structure in which a plurality of small openings that cannot pass when it becomes spherical due to tension.
