内に挿入されている。The ejector will be briefly explained. As shown in FIG. 2, the ejector 1 consists of a supply pipe 2 for supplying high-pressure driving water, a discharge pipe 3, and a suction pipe 4.
The tip of the bilge well 6 provided at the bottom 5' of the hold 5
inserted inside.
供給管２から駆動水を供給すると、ビルジウェル６内に
溜った洗浄汚水７は、吸引管４を通って排出管３から排
出される。When driving water is supplied from the supply pipe 2, the cleaning waste water 7 accumulated in the bilge well 6 passes through the suction pipe 4 and is discharged from the discharge pipe 3.
このような構造のエゼクタｌが各船倉５内に設けられ、
各エゼクタ１の排出管３はメイン排出管８に接続されて

えない。However, since the discharge capacity of each ejector 1 is small, the flow rate of the cleaning wastewater 7 flowing in the main discharge pipe 8 is slow. As a result, if the dust in the washed waste water 7 settles to the bottom of the main discharge pipe 6 and the main discharge pipe 8 becomes clogged, the washed waste water 7 cannot be discharged.
このために、第３図に示されるように、ビルジウェル６

法によっても十分に□ 洗浄汚水を排出できない場
合がある。For this purpose, as shown in FIG.
Washing waste water collected in a hopper 14 provided inside is poured 7 into the nozzle part a of the suction pipe 4 of the ejector 1 and sucked 7, and furthermore, the driving water in the supply pipe 2 is passed through the branch pipe 2a. It is conceivable to supply the cleaning wastewater to the nozzle section 4a, thereby increasing the transfer capacity of the cleaning wastewater. However, even with this method, it may not be possible to sufficiently discharge the washing wastewater.
この発明の目的は、洗浄汚水中の粉塵によってメイン排
出管が詰まるのを防止することができる排出装置を提供
することにある。An object of the present invention is to provide a discharge device that can prevent a main discharge pipe from being clogged with dust in washed waste water.
この発明は、各船倉の底に設けられたビルジウェルと、

することに％徴を有する。This invention features a bilge well provided at the bottom of each hold,
Discharge of washing sewage inside the hold, consisting of an ejector for discharging the washing sewage accumulated in the bilge well, and a main discharge pipe for collecting the washing sewage discharged from the ejector and discharging it outside the ship. In the apparatus, a main ejector provided at the downstream end of the main discharge pipe;
means for supplying seawater to the upstream end of the main discharge pipe, and has a function of discharging the wash water flowing through the main discharge pipe overboard together with the seawater by the main ejector.
この発明の一実施態様を図面を参照しながら説明する。 One embodiment of this invention will be described with reference to the drawings.
第１図は、この発明の一実施態様の配管の系統図である
。第１図に示されるように、複数個の船倉５の各々には
