Abstract

Cooling water inlet at a barge (10) comprised of a chamber (14), which is divided into sub chambers (16, 17) by a horizontally sloping strainer (15). A long pipe (21) extends from the upper sub chamber (17) through the strainer (15) and the lower sub-chamber (16) quite far under the bottom of the barge (22) and allows the intake of cooling water from a layer that can be expected as less contaminated than the surface water. Through the strainer's angled placing impurities collected during operation slid down toward a drain to transport them away (24). The pipe (21) that pivots around hinge joints (23) on its underside can temporarily be lifted away when thoroughly cleaning the strainer (15).<IMAGE>

Description

8304407-3 Denna är genom en mot horisontalplanet lutande sil 15 in- delad i ett undre delrum 16 - som kommunicerar med pumpen 12 - och ett övre delrum 17 som kommunicerar med vattenin- taget. 8304407-3 This is divided by a screen 15 sloping towards the horizontal plane into a lower subspace 16 - which communicates with the pump 12 - and an upper subspace 17 which communicates with the water intake.

Inom det undre delrummet 16 finns en rörstuds 19, för- sedd med stödfläns 20, vilken normalt uppbär ett intagsrör 21, vilket når ett gott stycke ner under prâmens botten 22.Within the lower subspace 16 there is a pipe stub 19, provided with a support flange 20, which normally carries an intake pipe 21, which reaches a good distance below the bottom 22 of the barge.

Silen 15 stöder normalt mot studsen 19 och är genom en gångled 23 vid sin undre längskant förbunden med en ränna 24, vilken står i förbindelse med en avloppsledning 25.The screen 15 normally supports the bounce 19 and is connected by a hinge 23 at its lower longitudinal edge to a gutter 24, which is connected to a drain line 25.

Genom att röret 21 når så långt ned under vattenytan som blir fallet här minskas risken för att större kring- flytande föremål sugs med genom intaget. Smärre föro- reningar, slam och dylikt, som kommer in i det övre delrum- met 17 fastnar på silen 15 och glider ned mot rännan 24.Because the pipe 21 reaches as far below the water surface as is the case here, the risk of larger floating objects being sucked in through the intake is reduced. Minor contaminants, sludge and the like, which enter the upper compartment 17 get stuck on the screen 15 and slide down towards the gutter 24.

Det går naturligtvis att anordna någon skrapnings- eller spolningsanordning som hjälper till att hälla silen ren.It is of course possible to arrange a scraping or rinsing device which helps to keep the strainer clean.

Avloppsledningen 25 står lämpligen i förbindelse med en ejektor som medger intermittent tömning av sådant som sam- lats på rännan 24.The drain line 25 is suitably connected to an ejector which allows intermittent emptying of such as has been collected on the gutter 24.

Röret 21 är vid sin överände försedd med en fläns 26 som normalt stöder mot silen 15. För att möjliggöra full- ständig rengöring av denna, kan röret 21 lyftas upp genom det övre delrummet 17, såsom antyds med streckade linjer vid 27. Det däck som upptill begränsar delrummet 17 är för- sett med en manhålslucka 28 av passande dimension. Detta däck är beläget ovanför vattenlinjen 29.The tube 21 is provided at its upper end with a flange 26 which normally supports the screen 15. To enable complete cleaning thereof, the tube 21 can be lifted up through the upper part space 17, as indicated by dashed lines at 27. The tire which at the top limiting the sub-space 17 is provided with a manhole cover 28 of suitable dimension. This deck is located above the waterline 29.

Silen 15 kan därefter svängas upp kring gångleden 23 till det med streckade linjer vid 30 visade läget samt spolas ren mot rännan 24, varvid på silen uppsamlat material glider ned på rännan, eventuellt kan filtret i detta läge spolas "underifrån".The screen 15 can then be swung up around the hinge 23 to the position shown in broken lines at 30 and rinsed clean against the gutter 24, whereby material collected on the screen slides down on the gutter, possibly the filter can in this position be rinsed "from below".

Den ovan beskrivna och på ritningen visade anordningen _är avsedd för ett visst inbyggnadsändamål, och utseende och placering av ingående komponenter kan komma att varieras inom ramen för efterföljande patentkrav beroende på lokala förhållanden.The device described above and shown in the drawing is intended for a specific installation purpose, and the appearance and location of constituent components may vary within the scope of the appended claims depending on local conditions.

Claims

8304407-3 PATENT REQUIREMENTS

Device for cooling water intake, characterized by a chamber (14) divided by a screen (15) into two sub-compartments (16, 17), a lower one (16) of which is connected to a pump (12 ), and an upper (17) via a pipe (21) projecting through the screen (15) and the lower space, communicates with ambient water at a level below the bottom (22) of the chamber.

Device according to Claim 1, characterized in that the screen (15) is inclined towards the horizontal plane in the working position, and is pivotable about a hinge (23) arranged at its lower side edge in connection with a gutter (24) for transporting away collected pollutants.

Device according to one of Claims 1 or 2, characterized (16), designed (16) designed to support the pipe (21), which can be pulled up through the upper subspace (17) when cleaning the screen within the lower subspace. (15) shall be undertaken.
