Description

143355143355

Opfindelsen angår et apparat af den i krav l's indledning angivne art. Den heri angivne rensning vedrører ikke blot i vandet flydende genstande, såsom stykker af træ og lignende urenheder, men isar fjernelse af væsker, som ikke er blandbare med vand, f.eks. olie, der flyder på vand. Tidligere kendte apparater til rensning af vandoverfladen har den ulempe, at de næsten ikke, eller i hvertfald på meget uøkonomisk måde fjerner væsker, som i særlig grad udgør sidstnævnte urenheder. Således kendes fra beskrivelsen til fransk patent nr. 1 550 426 et apparat af den indledningsvis angivne art, hvor der foran et sugeorgan er anbragt et legeme, som ligger lidt under vandoverfladen. Dette legeme benyttes til at opnå, at kun en relativ ringe vandmængde føres til sugeorganet. Under funktionen frembringes en ændring af vandniveauet, hvorved hovedsagelig de øverst liggende urenheder tvinges over legemet og hen imod en beholder. Legemet har funktion som en skumsamler, der hører til et sugeorgan, der er forbundet til en opsamlingsbeholder. 1 den foreliggende opfindelse har det omhandlede legeme en helt anden funktion, idet det i forbindelse med en oliespærring af afskumningstypen skal løse det problem, som er forårsaget af vandniveaustigningen foran sugeorganernes mundstykker. Hvis vandet strømmer i en retning, som er omtrent vinkelret på den langsgående retning af et skærmformet legeme (som følge af at nævnte legeme trækkes gennem vandet eller legemet er anbragt i en flod eller en kanal i en retning, som næsten er vinkelret på strømmen), finder en niveaustigning sted før skærmen, idet den rejser sig op mod skærmen. For at nå sugeorganet bør den flydende væskeformede urenhed overstige nævnte vandniveaustigning.The invention relates to an apparatus of the kind specified in the preamble of claim 1. The purification disclosed herein relates not only to liquid objects in the water, such as pieces of wood and similar impurities, but particularly to the removal of liquids which are immiscible with water, e.g. oil floating on water. Prior art apparatus for cleaning the surface of the water has the disadvantage that they hardly remove, or at least in a very uneconomical way, liquids which constitute, in particular, the latter impurities. Thus, from the specification of French Patent No. 1 550 426, there is known an apparatus of the kind mentioned in the preamble, in which a body located slightly below the water surface is arranged in front of a suction means. This body is used to ensure that only a relatively small amount of water is fed to the suction means. During the operation, a change in water level is produced, forcing mainly the upper impurities over the body and towards a container. The body functions as a foam collector belonging to a suction member connected to a collection container. In the present invention, the body of the present invention has a completely different function in that, in connection with a foam type oil barrier, it has to solve the problem caused by the water level rise in front of the suction nozzles. If the water flows in a direction approximately perpendicular to the longitudinal direction of a screen-shaped body (as a result of said body being drawn through the water or the body disposed in a river or channel in a direction almost perpendicular to the flow) , a level rise occurs before the screen as it rises toward the screen. In order to reach the suction means, the liquid liquid impurity should exceed said water level rise.

Derfor vil urenheder, såsom olie forblive med en vis afstand fra skærmen. Der er ingen mening i at anbringe sugeorganet i skærmen, således at den nederste kant af sugemundstykket falder sammen med vandniveauet med henblik på at tilvejebringe en økonomisk betjening. Som følge af den 143355 2 fremhævede vandniveaustigning vil sugemundstykket næppe absorbere olie. En økonomisk betjening bliver ikke tilvejebragt før en sænkning af vandoverfladen er blevet opnået før sugeorganets mundstykke. I det tilfælde vil olien, som skal absorberes, af sig selv blive ført til sugeorganet. På denne måde undgår man at bortsuge store mængder vand, som standser den naturlige strømning af olie, som skal absorberes.Therefore, impurities such as oil will remain at some distance from the screen. There is no point in placing the suction member in the screen so that the lower edge of the suction nozzle coincides with the water level in order to provide economical operation. Due to the 143355 2 highlighted water level rise, the suction nozzle will hardly absorb oil. An economical operation is not provided until a lowering of the water surface has been achieved before the suction nozzle. In that case, the oil to be absorbed will by itself be fed to the suction means. In this way, large quantities of water are avoided, which stops the natural flow of oil to be absorbed.

Det angivne problem løses ifølge opfindelsen ved, at det indledningsvis angivne apparat er ejendommeligt ved det i krav l’s kendetegnende del angivne. Det heri angivne strømningslegeme fungerer uafhængigt af et sugeorgans mundstykke i et olierensningsapparat af afskumningstypen.The present problem is solved according to the invention in that the apparatus stated at the outset is peculiar to the characterizing part of claim 1. The flow body disclosed herein operates independently of a suction nozzle in a foam type oil cleaning apparatus.

Desuden er strømningslegemet særlig egnet til at tvinge vand under strømningslegemet, således at vandniveauet bliver højere foran end bag ved strømningslegemet.In addition, the flow body is particularly suitable for forcing water below the flow body so that the water level becomes higher at the front than behind the flow body.

For at være i stand til at dimensionere vandoverfladevariationen, er strømningslegemet understøttet på en sådan måde, at det er drejeligt i forskellige retninger og bevægeligt i forhold til sugeorganet.In order to be able to dimension the water surface variation, the flow body is supported in such a way that it is pivotable in different directions and movable relative to the suction member.

Opfindelsen skal i det følgende nærmere beskrives med henvisning til tegningen, hvorpå: fig. 1 er et skematisk billede af dannelsen af en vandoverflade sænkning, fig. 2 er et skematisk billede af et strømningslegeme til opnåelse af en vandoverfladesænkning, fig. 3 viser en mulig stilling for apparatet ifølge opfindelsen, fig. 4 viser en anden mulig stilling for apparatet ifølge opfindelsen, og 3 143355 fig. 5 viser sugeorganet og anbringelsen af strømningslegemet til opnåelse af vandniveausænkningen i den til fig. 4 svarende udførelsesform.The invention will now be described in more detail with reference to the drawing, in which: FIG. 1 is a schematic view of the formation of a water surface lowering; FIG. 2 is a schematic view of a flow body for obtaining a water surface lowering; FIG. 3 shows a possible position for the apparatus according to the invention; FIG. 4 shows another possible position for the apparatus according to the invention, and FIG. 5 shows the suction means and the positioning of the flow body to achieve the water level lowering in the FIG. 4 corresponding embodiment.

I eksemplet med udførelsesformen, som er vist i fig. 1, bliver vandoverflade sænkningen, eller vandniveausænkningen, som tilsigtet ifølge opfindelsen, tilvejebragt ved at anbringe et strømningslegeme i form af en strimmelformet plade 1, hvis længdeakse praktisk taget er parallel med vandniveauet 2, idet forsiden af pladen er anbragt praktisk taget vinkelret på vandniveauet. Den øverste kant af den strimmelformede plade 1 ligger omkring 20 cm under vandniveauet 2. Pilene, som viser strømningsretningen, er angivet med henvisningsbetegnelsen 3. På den anden side af pladen 1 er den deraf følgende strømningsretning angivet med pile 4.In the example of the embodiment shown in FIG. 1, the water surface lowering, or the water level lowering as intended according to the invention, is provided by disposing a flow body in the form of a strip-shaped plate 1, whose longitudinal axis is substantially parallel to the water level 2, the front of the plate being positioned substantially perpendicular to the water level. The upper edge of the strip-shaped plate 1 is about 20 cm below the water level 2. The arrows showing the direction of flow are indicated by the reference 3. On the other side of the plate 1 the resulting flow direction is indicated by arrows 4.

På havet bliver nævnte strøm- og følgestrømsretninger f.eks. opnået ved at bevæge pladen i forhold til det omgivende vand i retning af en pil 5. I en kanal eller en flod kan nævnte strømme fremkomme uden at bevæge eller forskyde pladen 1. Et henvisningsmærke 6 viser vandniveausænkningen, som frembringes ved anvendelse af pladen 1 og gensidig forskydning af vandet og pladen. Som det nærmere fremgår af fig. 2, er de langsgående kanter af den strimmelformede plade 1 bukket over en vinkel på næsten 90°. Den øverste kant 7 og den nederste kant 8 er bukket i modsatte retninger. Hvor den nederste kant 8 er bukket i retning med vandstrømmen, som strømmer forbi den strimmelformede plade 1, er den øverste kant 7 bukket i retning modsat vandstrømmen, som passerer pladen 1. Herved opnås en formindsket vandmodstand. ved bevægelse af pladen mod vandstrømmen.At sea, the said current and consequent current directions, e.g. obtained by moving the plate relative to the surrounding water in the direction of an arrow 5. In a channel or river, said streams may appear without moving or displacing the plate 1. A reference mark 6 shows the water level decrease produced by using the plate 1 and mutual displacement of the water and the plate. As will be more apparent from FIG. 2, the longitudinal edges of the strip-shaped plate 1 are bent at an angle of almost 90 °. The upper edge 7 and the lower edge 8 are bent in opposite directions. Where the lower edge 8 is bent in the direction of the flow of water passing past the strip-shaped plate 1, the upper edge 7 is bent in the direction opposite to the flow of water passing through the plate 1. This results in a reduced water resistance. by moving the plate towards the water flow.

Det bemærkes, at et sugeorgan 16 inklusive det ovenfor beskrevne strømningslegeme 1 til tilvejebringelse af en vand-niveausænkning kan være anbragt nær en åbning i et skærmformet legeme, som kan flyde i vandet. Åbningen er så fortrinsvis anbragt ved et sted i det skærmformede legeme, som 4 143355 repræsenterer et knækpunkt i apparatet ifølge opfindelsen.It should be noted that a suction member 16 including the flow body 1 described above to provide a water level lowering may be disposed near an aperture in a screen-shaped body which can flow into the water. The aperture is then preferably located at a location in the screen-shaped body, which represents a break point in the apparatus of the invention.

Ved rensning af vandoverfladen i en flod eller kanal med strømmende vand kan en slags flydende skærm 12 (fig. 3), som strækker sig fra den ene bred 9 til den anden bred 10, monteres næsten vinkelret på strømningsretningen (pilen 11). Med den ene af bredderne, i dette tilfælde bredden 9, danner denne flydende skærm 12 så en vinkel på mindre end 90°, hvor det forurenede flodvand bliver koncentreret. I dette tilfælde er sugeorganet 16, som indeholder strømningslegemet 1, monteret foran sugeorganets sugemundstykke til frembringelse af en vandniveausænkning, anbragt ved et sted 13. Så bliver det forurenede vand koncentreret ved stedet 13, som følge af samvirket mellem den flydende skærm 12 og den faste bred 9. I dette tilfælde udgør skærmen 12 og bredden 9 derfor tilsammen det skærmformede legeme, i hvilket en åbning er til stede ved 13, hvor sugeorganet 16 er anbragt.When cleaning the water surface in a river or channel with flowing water, a kind of floating screen 12 (Fig. 3) extending from one bank 9 to the other bank 10 can be mounted almost perpendicular to the flow direction (arrow 11). With one of the widths, in this case the width 9, this floating screen 12 then forms an angle of less than 90 ° where the polluted river water becomes concentrated. In this case, the suction member 16, which contains the flowing body 1, mounted in front of the suction nozzle of the suction means to produce a water level lowering, is placed at a location 13. Then the contaminated water is concentrated at the location 13 due to the interaction between the liquid screen 12 and the solid. wide 9. In this case, the screen 12 and the width 9 therefore together constitute the screen-shaped body, in which an opening is present at 13, where the suction means 16 is arranged.

I en for bred flod, en for bred kanal eller i åbent farvand kan det skærmformede legeme være udformet af en flydende skærm 12, som trækkes af en slæbebåd eller et andet fartøj 14 (fig. 4). Henvisningstallet 15 angiver træktove. I denne udførelsesform er sugeorganet 16 til stede ved det sted, hvor der er kortest afstand imellem skærmen 12 og fartøjet 14. Dette sted er angivet mere detaljeret i fig.In a river too wide, a channel too wide, or in open waters, the screen-shaped body may be formed by a floating screen 12 drawn by a tug or other vessel 14 (Fig. 4). Reference numeral 15 indicates pull ropes. In this embodiment, the suction member 16 is present at the point where the shortest distance between the shield 12 and the vessel 14. This location is indicated in more detail in FIG.

5. Henvisningstallet 17 angiver en flyder for skærmen 12, hvilken flyder 17 er forblindet med slæbebåden ved hjælp af træktove. Skærmen 12 er udformet som to parallelt forløbende delskærme 12a og 12b. Henvisningstallet 16 angiver sugeorganet. Strømningslegemet 1 til at opnå vandniveau-sænkningen under brugen af apparatet ifølge opfindelsen er til stede i åbningen af det skærmformede legemes åbning, som findes mellem delskærmen 12b og flyderen 17.5. The reference numeral 17 indicates a float for the screen 12, which float 17 is blinded by the tug by means of pull ropes. The shield 12 is formed as two parallel-running sub-screens 12a and 12b. Reference numeral 16 denotes the suction means. The flow body 1 for achieving the water level lowering during the use of the apparatus of the invention is present in the opening of the screen-shaped body which is located between the sub-screen 12b and the float 17.
