Description
Oppfinnelsens område Field of the invention
Den foreliggende oppfinnelse vedrører en inntaksledning til en lukket eller semilukket merd, omfattende et filter montert på et vanninnløp til inntaksledningen for å hindre inntak av uønskete partikler eller organismer som maneter, lus, amøber og giftige alger i alle vannsjikt, der filteret er neddykket og utformet tilnærmet som en sylinder med en filterduk eller not som utgjør veggene sammen med et rammeverk som omslutter vanninnløpet for tilførsel av vann inn i merden. The present invention relates to an intake line for a closed or semi-closed cage, comprising a filter mounted on a water inlet to the intake line to prevent the intake of unwanted particles or organisms such as jellyfish, lice, amoebae and toxic algae in all water layers, where the filter is submerged and designed approximated as a cylinder with a filter cloth or groove forming the walls together with a framework enclosing the water inlet for the supply of water into the cage.
Oppfinnelsens bakgrunn The background of the invention
Det er kjent flere typer filter på inntaksledninger i lukkede merder og ellers andre inntaksledninger som til pumpestasjoner etc. Disse filtrene er betegnet som trommelfiltre og er fortrinnsvis på trykksiden av selve pumpeenhetene i et slikt rørsystem. For lukkete merder betyr dette ekstra stort plassbehov for installasjonen og tilsvarende stort behov for ekstra oppdrift. Dette igjen fører til en dyr løsning. l dag er det vanlig med en enkel rist eller not på innløpet i lukkete merder. På grunn av maneter, begroning og fremmedpartikler vil det tette seg igjen og kreve mye etterkontroll og vedlikehold. Med den foreskrevne oppfinnelse er det tatt utgangspunkt i en lukket eller semilukket merdinntaksledning som kan løse problemene med lus, maneter, amøber, giftige alger og andre parasitter i alle vannsjikt. Oppfinnelsen kan i og for seg også anvendes på inntaksledning på landanlegg for oppdrett av fisk. Several types of filters are known on intake lines in closed cages and other intake lines such as for pump stations etc. These filters are designated as drum filters and are preferably on the pressure side of the pump units themselves in such a pipe system. For closed cages, this means an extra large space requirement for the installation and a correspondingly large need for extra buoyancy. This in turn leads to an expensive solution. Today, it is common to have a simple grate or groove on the inlet in closed cages. Due to jellyfish, fouling and foreign particles, it will clog up and require a lot of follow-up and maintenance. With the prescribed invention, the starting point is a closed or semi-closed multi-intake line that can solve the problems with lice, jellyfish, amoebas, toxic algae and other parasites in all water layers. The invention in and of itself can also be applied to intake lines on land-based plants for fish farming.
Omtale av kjent teknikk Discussion of prior art
Av teknikk som er kjent på området nevnes fem patentsøknader herunder. Den norske patentsøknaden NO175341B omhandler en fremgangsmåte for tilførsel av vann til en lukket merd for fiskeoppdrett. Merden settes i rotasjon ved at sjøvann pumpes inn fra en nedsenket inntaksledning med filter ut i en horisontal retning i merden. Dette setter vannmassen i merden i rotasjon. Bevegelsen kan reguleres ved å justere hastigheten til innsprøytingen eller ved å splitte vannstrømmen i en eller flere retninger. Of the technology known in the area, five patent applications are mentioned below. The Norwegian patent application NO175341B deals with a method for supplying water to a closed cage for fish farming. The cage is set in rotation by pumping seawater in from a submerged intake line with a filter out in a horizontal direction into the cage. This sets the mass of water in the cage in rotation. The movement can be regulated by adjusting the speed of the injection or by splitting the water flow in one or more directions.
Publikasjonen EP 2623176 A2 omtaler et rensesystem for et siktinntak i et vanninntakssystem. Rensesystemet spyler sikten fra innsiden og/eller utsiden ved hjelp av bevegelige dyser som plasseres enten konsentrisk ved sylindrisk sikt, eller plant ved flatt sikt. The publication EP 2623176 A2 mentions a cleaning system for a sieve inlet in a water intake system. The cleaning system flushes the screen from the inside and/or the outside using movable nozzles that are placed either concentrically in the case of a cylindrical screen, or flat in the case of a flat screen.
Den amerikanske patentsøknaden US 3242872 A omtaler inntak av vann via en nedsenket vanninntaksledning som har en påmontert sikt/filter som renses ved at sikten spyles av bevegelige spyledyser. The American patent application US 3242872 A mentions the intake of water via a submerged water intake line which has an attached sieve/filter which is cleaned by the sieve being flushed by movable flushing nozzles.
Publikasjonen US 4210539 A omhandler bevegelige spyledyser for rensing av filter/sikt i en nedsenket vanninntaksledning som styres av tilført trykksatt vann og som renser filteret/sikten og setter den i bevegelse. The publication US 4210539 A deals with movable flushing nozzles for cleaning a filter/screen in a submerged water intake line which is controlled by supplied pressurized water and which cleans the filter/screen and sets it in motion.
Oppsummering av oppfinnelsen Summary of the invention
Oppfinnelsen omhandler en inntaksledning til en lukket eller semilukket merd med et filter montert på et vanninnløp til inntaksledningen for å hindre inntak av uønskete partikler eller organismer som maneter, lus, amøber og giftige alger i alle vannsjikt, der filteret er neddykket og utformet tilnærmet som en sylinder med en filterduk eller not som utgjør veggene sammen med et rammeverk som omslutter vanninnløpet for tilførsel av vann inn i merden. Oppfinnelsen er kjennetegnet ved at filteret omfatter en innvendig vanndrevet og roterende bom inneholdende et vertikalt spylerør bestående av spyledyser som står rettet mot og i en viss avstand fra filterduken, samt at bommen har hovedsakelig horisontalt rettete dyser som er innrettet til å skape en reaksjonskraft som forårsaker et dreiemoment om bommens aksel for å sette bommen i en kontrollert rotasjon. The invention relates to an intake line to a closed or semi-closed cage with a filter mounted on a water inlet to the intake line to prevent the intake of unwanted particles or organisms such as jellyfish, lice, amoebas and toxic algae in all water layers, where the filter is submerged and designed approximately as a cylinder with a filter cloth or groove that forms the walls together with a framework that encloses the water inlet for the supply of water into the cage. The invention is characterized by the fact that the filter comprises an internal water-driven and rotating boom containing a vertical flushing pipe consisting of flushing nozzles which are directed towards and at a certain distance from the filter cloth, and that the boom has mainly horizontally directed nozzles which are designed to create a reaction force which causes a torque about the boom's axis to set the boom in a controlled rotation.
Filteret kan være omsluttet av en utvendig ring som inneholder dyser som delvis kan sette opp en strøm i flere retningen som gjør det mulig å bevege ringen opp og ned langs overflaten av filterduken. Videre kan filteret ha en tett ende som er tilsluttet vanninnløpet til inntaksledningen. The filter can be enclosed by an outer ring containing nozzles which can partially set up a flow in several directions which makes it possible to move the ring up and down along the surface of the filter cloth. Furthermore, the filter can have a closed end which is connected to the water inlet of the intake line.
Inntaksledningen kan være fleksibel, så som en slange som kan trekke seg sammen slik at filteret kan løftes opp til en fast posisjon i vertikalsøylen i sjøen. The intake line can be flexible, such as a hose that can contract so that the filter can be lifted up to a fixed position in the vertical column in the sea.
Den roterende bommen kan være opplagret i et nedre og et øvre lager og der det nedre lageret er forbundet med en trykkvannsledning for å motta trykkvann, i det bommens aksling er utformet som et hult rør. The rotating boom can be stored in a lower and an upper bearing and where the lower bearing is connected to a pressurized water line to receive pressurized water, in which the shaft of the boom is designed as a hollow tube.
Bommens vertikale spyledyser som er rettet mot filterduken kan være justerbar i avstand ved at dysene kan skrus inn og ut fra bommens vertikale spylerør. The boom's vertical spray nozzles, which are aimed at the filter cloth, can be adjusted in distance by screwing the nozzles in and out from the boom's vertical spray pipe.
Ringen kan videre få tilført trykkvann fra en trykkvannsledning og der bevegelsen styres ved hjelp av en trykkvannspumpe som startes og stoppes intermittent. The ring can also be supplied with pressurized water from a pressurized water line and where the movement is controlled using a pressurized water pump which is started and stopped intermittently.
Ringen kan være utformet helt eller delvis hul for å kunne ha oppdrift for å bevege seg opp og ned. I en alternativ utforming kan ringen være utformet med innadvendte børster. The ring can be designed to be completely or partially hollow to be able to have buoyancy to move up and down. In an alternative design, the ring can be designed with inward facing brushes.
Ringen kan videre være utstyrt med innadvendte og skråstilte dyser som både spyler filterduken ren og samtidig setter opp en vannjetstrøm ut fra dysene som kan drive ringen i en kontrollert bevegelse opp og ned utenpå filterduken. The ring can also be equipped with inward-facing and angled nozzles which both rinse the filter cloth clean and at the same time set up a water jet from the nozzles which can propel the ring in a controlled movement up and down on the outside of the filter cloth.

Det henvises til figurer som vedlagt. Reference is made to the attached figures.
Figur 1 viser et filter 1 som er plassert på sugensiden av en pumpe 18 i en inntaksledning 19 som er koblet til en flytekrage 20 i en lukket merd 21 og suger inn vann fra sjøen på et nivå som er praktisk for den aktuelle lokaliteten og som samtidig som filteret eller nota holdes ren ved en roterende bom 6 med spylerør 6a rettet utad mot en filterduk 4, not eller barriere skal hindre lus, maneter, amøber og andre parasitter å sette seg fast i denne og tette et vanninnløp 22 til inntaksledningen 19 til den lukkete merden 21 Figure 1 shows a filter 1 which is placed on the suction side of a pump 18 in an intake line 19 which is connected to a float collar 20 in a closed cage 21 and sucks in water from the sea at a level which is practical for the location in question and which at the same time as the filter or net is kept clean by a rotating boom 6 with flushing pipe 6a directed outwards towards a filter cloth 4, net or barrier must prevent lice, jellyfish, amoebas and other parasites from getting stuck in it and blocking a water inlet 22 to the intake line 19 to the closed the cage on the 21st
På filteret 1 eller nota er det opplagret en roterende bom 6 som er opplagret i et øvre lager 7 og i et nedre lager 8 og som får tilført trykkvann gjennom en trykkvannsledning 10 og som videre er hul i den vertikale del 11 der det er et sett spyledyser 12 på det vertikale spylerøret 6a og et sett horisontale eller tilnærmet horisontalt rettete dyser 6b som skal skape en reaksjonskraft som forårsaker et dreiemoment om bommens 6 aksel 6c og som dermed setter bommen i en kontrollert rotasjon og som da vil spyle filterduken eller nota ren i hele filterets overflate 13. On the filter 1 or note is stored a rotating boom 6 which is stored in an upper bearing 7 and in a lower bearing 8 and which is supplied with pressurized water through a pressurized water line 10 and which is further hollow in the vertical part 11 where there is a set spray nozzles 12 on the vertical spray pipe 6a and a set of horizontal or nearly horizontally directed nozzles 6b which are to create a reaction force which causes a torque about the shaft 6c of the boom 6 and which thus sets the boom in a controlled rotation and which will then flush the filter cloth or nota clean in the entire surface of the filter 13.
Filteret 1 på utførelseseksempelet er vist som en sylinder der øvre flate 14 og bunnflaten 15 er tett og utført med plast eller metall, mens sideflatene består av et rammeverk og selve nota eller filterduken 4 der vannet til den lukkete merden suges inn, uten at dette påvirkes av reingjøringen av filterduken 4. The filter 1 on the design example is shown as a cylinder where the upper surface 14 and the bottom surface 15 are tight and made of plastic or metal, while the side surfaces consist of a framework and the filter cloth itself 4 where the water of the closed cage is sucked in, without being affected of the cleaning of the filter cloth 4.
Det er på figur 1 også vist en ring 5 som en ekstra sikring for automatisk rengjøring ved at denne inneholder et sett eller antall dyser med innbyrdes avstand rettet mot filterduken 4 eller nota og et sett eller antall skrått nedadrettende eller vertikalt rettete dyser 5a for å kunne bevege spyleringen opp og ned for ekstra reingjøring av maneter, lus og partikler og groe som har satt seg fast og må spyles av i en annen retning enn dysene. Figure 1 also shows a ring 5 as an additional safeguard for automatic cleaning in that it contains a set or number of nozzles with a mutual distance directed towards the filter cloth 4 or nota and a set or number of obliquely downwards or vertically directed nozzles 5a to be able move the flushing ring up and down for additional cleaning of jellyfish, lice and particles and growth that have stuck and must be flushed off in a different direction from the nozzles.
Dette er ifølge oppfinnelsen gjort ved et filter 1 på innløpet til en inntaksledning 19 i en lukket merdkonstruksjon 21 som skal hindre inntak av maneter, lus og andre uønskete akvatiske organismer og partikler i lukkete merder eller og for seg som også kan brukes i rørledningsinntak til settefisk og resirkuleringsanlegg. According to the invention, this is done by a filter 1 on the inlet to an intake line 19 in a closed cage structure 21 which is to prevent the intake of jellyfish, lice and other unwanted aquatic organisms and particles in closed cages or and separately which can also be used in pipeline intakes for hatchery fish and recycling facilities.
Filteret 1 består av et «hus» eller en «korg» som er festet utenpå inntaksledningens 19 innløpstuss via en flens på en lukket merd eller en generell inntaksledning av sjø og ferskvann. The filter 1 consists of a "house" or a "basket" which is attached to the outside of the intake pipe 19 inlet via a flange on a closed cage or a general sea and fresh water intake pipe.
Selve filterhuset har en betydelig større diameter enn selve innløpet for å redusere strømhastigheter inn i innløpet og dermed redusere antall partikler som blir sugd inn i filteret. Huset består av et kraftig rammeverk og et filter, eller kan utgjøre en not med liten maskevidde for å hindre villfisk og maneter å komme inn i merden. På denne måten oppnås en lavhastighets strøm inn i inntaksledningen 19 og som gjør det mulig å bruke en spyler til å få vekk uønskete maneter, lus, amøber og andre partikler og organismer som er skadelig for fisken i merden eller det magasin som skal holdes fritt for uønskete partikler eller organismer. The filter housing itself has a significantly larger diameter than the inlet itself to reduce flow velocities into the inlet and thus reduce the number of particles that are sucked into the filter. The house consists of a strong framework and a filter, or can form a groove with a small mesh size to prevent wild fish and jellyfish from entering the cage. In this way, a low-speed current is obtained into the intake line 19 and which makes it possible to use a flusher to get rid of unwanted jellyfish, lice, amoebas and other particles and organisms that are harmful to the fish in the cage or the magazine that must be kept free of unwanted particles or organisms.
Videre består filteret av et roterende spylerør som får tilført vann med høyt trykk og består av et antall vertikale spyledyser posisjonert i et antall vertikale sett og med en viss avstand fra selve filterduken eller noten, og som dermed spyler eller vasker filteret rent, ved at rørarmen dreies rundt av et sett horisontalt rettete dyser som da tjener som et sett vannjetter og gjør at filteret kan spyles kontinuerlig samtidig som inntak av vann til den lukkete merden eller i og for seg alle typer vanninntak, skjer uavhengig av spylingen. Furthermore, the filter consists of a rotating flushing pipe which is supplied with water at high pressure and consists of a number of vertical flushing nozzles positioned in a number of vertical sets and at a certain distance from the filter cloth or groove itself, and which thus flushes or washes the filter clean, by the pipe arm is turned around by a set of horizontally directed nozzles which then serve as a set of water jets and enable the filter to be flushed continuously at the same time as the intake of water to the closed cage or in and of itself all types of water intake, takes place independently of the flushing.
Det er ønskelig at dette filteret er festet til en fleksibel slange som gjør at filteret enkelt kan trekkes opp til overflaten og eventuelt posisjoneres i den dybde som ønskes ut fra vannkvalitet og vanntemperatur. It is desirable that this filter is attached to a flexible hose which means that the filter can easily be pulled up to the surface and possibly positioned at the desired depth based on water quality and water temperature.
Spylevann kan tilføres via en trykkpumpe som er montert i flytekragen og har den nødvendige kapasitet og trykk til å spyle og dreie renserøret rundt med en konstant og kontrollert måte. Flushing water can be supplied via a pressure pump that is mounted in the float collar and has the necessary capacity and pressure to flush and rotate the cleaning pipe in a constant and controlled manner.
Som en ekstra sikkerhet kan det monteres en ring 5 som omslutter filterhuset og som består av spyledyser som også spyler filteret eller noten ren dersom konsentrasjonen av partikler, lus eller andre uønskete partikler oppstår lokalt eller i perioder av året. Den ekstra spyleringen drives opp og ned av spyledyser og en egenoppdrift i selve ringkammeret, der spyledysene kan rettes på skrå inn mot filterduken eller noten og dermed få en skyvekraft i bevegelsesretningen og da virke som en vannjet. As an extra measure of safety, a ring 5 can be mounted which surrounds the filter housing and which consists of flushing nozzles which also flush the filter or the groove clean if the concentration of particles, lice or other unwanted particles occurs locally or during periods of the year. The additional flushing ring is driven up and down by flushing nozzles and a self-buoyancy in the ring chamber itself, where the flushing nozzles can be directed at an angle towards the filter cloth or groove and thus get a thrust in the direction of movement and then act as a water jet.
Ringen 5 kan erstatte bommen 6 der filteret kan holdes reint også kun ved spyleringen 5, ved at dysene 5a kan innrettes slik at de kan spyle og drive ringen 5 opp og ned omsluttet filteret 4 eller nota og dels ved at ringen 5 er hul og kan inneha oppdrift. The ring 5 can replace the boom 6 where the filter can be kept clean also only with the flushing ring 5, by the fact that the nozzles 5a can be arranged so that they can flush and drive the ring 5 up and down enclosing the filter 4 or nota and partly by the fact that the ring 5 is hollow and can possess buoyancy.
Både bommens 6 spylerør 6a og spyleringen kan få trykkvann tilført via samme rørledningen 10 eller separat med to rørledninger 10a,10b og drives opp og ned enten ved at trykkvannet kan styres intermittent og suksessivt for å kjøre ringen 5 opp og ned alt etter hvor mye partikler eller maneter eller lus på lokaliteten. Normalt sett kan filteret i fungere selv uten ringen ved at dette renses kun med spylerøret som drives kontinuerlig rundt av trykkvannet gjennom dysene. Both the boom's 6 flushing pipe 6a and the flushing ring can have pressurized water supplied via the same pipeline 10 or separately with two pipelines 10a, 10b and are driven up and down either by the pressurized water can be controlled intermittently and successively to drive the ring 5 up and down depending on the amount of particles or jellyfish or lice on the site. Normally, the filter i can function even without the ring, as this is only cleaned with the flushing tube which is continuously driven around by the pressurized water through the nozzles.
Det er vist på fig. 6 en fleksibel inntaksledning i utførelseseksempelet som dermed gjør det mulig å plassere inntaket på forskjellige nivåer i sjøen med dertil egnet temperatur for fisken i den lukkete merden 21 og gjør det mulig med en enkel service av filteret 1 ved å hale filteret 1 kontrollert for eksempel mot overflaten via en vire, tau eller kjetting 23 med en vinsj 25 på en arbeidsbåt 26 eller merdvinsj på flytekragen. It is shown in fig. 6 a flexible intake line in the design example which thus makes it possible to place the intake at different levels in the sea with a suitable temperature for the fish in the closed cage 21 and makes it possible to easily service the filter 1 by hauling the filter 1 controlled for example towards the surface via a wire, rope or chain 23 with a winch 25 on a work boat 26 or cage winch on the floating collar.
