Definitions

  • the present invention relates to a cleaning system and method for removing multicellular ectoparasites from the surface of fish.

  • the multicellular ectoparasites referred to here relate to all types of parasites and creatures that attach themselves to the outside of fish, as, for example, lice (sea lice), parasites, leeches and insects.

  • the cleaning pipe is provided with nozzles that are connected to a water pump for cleaning the outside of the fish by utilising the force of the water jet against the skin of the fish.
  • the nozzles are directed towards the outside of the fish such that an effective yet gentle cleaning of the surface of the fish is achieved inasmuch as the force of the water jet against the fish's skin is greater than the force with which the sea lice grip onto the skin.
  • the water jet thus provides a mechanical dislodging effect in that it is directed in towards the skin of the fish.
  • NO301440 describes a pump device of the ejector type that is suitable for transport of live fish.

  • the main object of the invention is to find an efficient, pollution-free and expedient method for removing the multicellular ectoparasites, with a further object of the invention being to increase the performance, capacity and usefulness of the equipment that is known to date, and render it useful on a large scale by increasing its efficiency and capacity.
  • an apparatus that provides an improved removal of the multicellular ectoparasites from the surface of fish. This is achieved by the invention as disclosed in the independent claims, embodiments of the invention being disclosed in the dependent claims.
  • the cleaning effect is improved in that gas bubbles are produced in a cleaning water flow that is directed towards the surface of fish in order to remove the multicellular ectoparasites (external parasites).
  • the production and distribution of gas bubbles in the cleaning water flow results in a mixture being obtained between the gas bubbles and at least some parts of the water in the cleaning water flow. This mixture is directed towards the surface of the fish and can be brought into the proximity of or in contact with the multicellular ectoparasites, i.e., the lice and any other parasites on the surface of the fish.

  • the invention is particularly suitable for use together with a transport system that is employed to move fish from one location to another.
  • An improved cleaning system to remove the multicellular ectoparasites from the surface of the fish will result in a qualitatively improved cleaning process and a quantity increase in the form of an increase in the amount of fish passed through the .transport system per unit of time compared with known equipment.
  • Examination of the fish has revealed that with the cleaning system according to the invention, the sea lice are removed more effectively from the surface of the fish compared with known systems of a similar kind, which have an efficiency where approximately 60% of the sea lice are removed from the surface of the fish.
  • the cleaning system according to the invention has been tried out through repeated testing, and it was demonstrated that the invention gives about 15% more delousing compared with known systems of a similar kind, without this appearing to affect the health of the fish.

  • the transport system can be designed such that fish can be moved between different levels.
  • a cleaning water flow in the form of a flushing jet is used that is directed against the surface of the fish, the flushing effect against the fish varying with the fish's radial distance to the nozzle and the angle of the flushing jet relative to the surface of the fish.
  • the fish, together with water, are pushed into the transport system because of the lower pressure that is there.
  • a pressure difference is obtained between the ambient pressure and the pressure that is confined between the inside of the carapace and the skin of the fish.
  • the difference in pressure gives a net force with direction which helps the sea lice to become dislodged from the surface of the fish.
  • the cleaning system comprises a cleaning water flow containing gas bubbles in a mixture with at least some parts of the water in the cleaning water flow.
  • the cleaning water flow containing the mixture can be directed towards the surface of the fish through a cleaning device that is incorporated in a transport system for fish, in an ejector device incorporated in the fish transport system, or in another suitable way which allows the cleaning water flow to have an effective setting angle towards the surface of the fish.
  • the transport system carries the fish in water together with fish feed and other substances necessary in connection with the farming of fish.
  • the fish are weighed and counted at a suitable point in the transport system.
  • the transport system has equipment for collecting the multicellular ectoparasites that are removed from the surface of the fish.
  • the fish can be sorted according to size and this sorting can take place under water.
  • the transport system is arranged such that it has a siphon-like design, but according to this embodiment the transport system does not use gravity as a driving force as is the case in siphon systems.
  • the transport system comprises, according to this embodiment, a number of pipes that are assembled so as to form a transport pipe with an inlet end and an outlet end, where the water flow carries the fish through a main duct formed in the transport pipe.
  • the inlet end and the outlet end are in water with the surface at the same level, and the pressure conditions are thus identical at both ends of the pipe. There is therefore no force of pressure to push the gas or water through the transport pipe.
  • Such a force of pressure can be provided using a pump.
  • a possible way of achieving gentle handling of the fish to be transported whilst a necessary force of pressure is provided to move the water flow with the fish through the pipe arrangement is to use an ejector device that is connected to the pipe arrangement.
  • the ejector device can be designed in different ways, but will in an embodiment comprise a pipe for carrying the fish in the water flow.
  • a nozzle construction that has a throughgoing main duct through which the water flow containing the fish is to be passed.
  • the nozzle construction may be positioned inside the ejector device such that there is at least one ejector nozzle between the inlet end and the outlet end.
  • This may be a continuous ejector nozzle that runs around the main duct and which may be annular, or may be provided in that a plurality of slot openings are arranged side by side.
  • the ejector nozzle(s) can be formed in the nozzle construction itself and be positioned radially outside the main duct of the nozzle construction.
  • the nozzle construction does not project from the wall of the ejector device and will thus not be an obstacle to the transport in the main duct. or have any harmful effect on the fish being transported.
  • the nozzle construction will preferably be configured to match the circumference of the main duct through the ejector device.
  • the ejector device is configured such that an injection water flow can be passed in through the ejector nozzle and into a main water flow that is passed through the main duct.
  • a water pump for introduction of an injection water flow into the ejector device can be connected to a feed pipe that is configured in the ejector device.
  • the injection water flow is delivered at a pressure through the ejector nozzle that is higher than atmospheric pressure and is focused towards the surface of the fish to remove the multicellular ectoparasites therefrom.
  • the ejector works in the following way:
  • the injection water is forced through the ejector nozzle and into the main flow that is transported through the main duct through the ejector device.
  • the injection from the ejector nozzle will have the appearance of a funnel or hollow cone in the main duct.
  • the injection flow works as a force, whose physical source consists of a hollow cone of accelerated water that carries with it and pushes the main flow at an angle towards the centre of the main duct where also the apex of the cone will essentially be located, and which, if other directions of force had not come into play, would have given the main water flow a conical shape.
  • the water cone from the ejector nozzle has an internal funnel form.
  • the external conical form or the internal funnel form is formed by water which flows at great speed from the ejector nozzle towards the centre of the main duct.
  • the conical funnel consisting of accelerated water, has a pressure-increasing effect on its outside, whilst on the inside it has a pressure-reducing effect. This effect arises owing to friction between the accelerated liquid and the medium in which it moves. Before the start of the main transport, this medium is basically air.
  • the water flow in the funnel form carries with it air particles that are moved to the outside of the conical form. This reduces the pressure on the inside of the funnel form and lowers the pressure throughout the part of the main duct which runs from and is on the same side of the ejector device as the mass that is to be moved. This means that the relative atmospheric pressure becomes greater than the pressure in the main duct, and the atmospheric pressure presses the water up through the main duct.
  • the main duct will gradually be filled with water. And as the part of the transport pipe which comes after the ejector device is also filled with water, the weight of the vertical water column, from the outlet end to the highest point of the main duct, weakens the counterforce from the atmospheric pressure that the water flow from the ejector nozzle meets at the beginning. The counterforce is smallest when the main duct is filled with water on both sides of the ejector nozzle.
  • the nozzle construction of the ejector device must be adapted to the fish size so that the fish can pass freely through the main duct of the nozzle construction. The fish are transported in the main duct and through the funnel/conical form that is formed when the injection water flow is forced through the ejector nozzle and into the main duct as described above.
  • the velocity of the water in the funnel-shaped water jet is much greater than the speed of the water and fish that are to pass through it.
  • a flushing effect is therefore obtained as the fish pass the ejector nozzle and the injection water flow functions as a cleaning water flow when it strikes the surface of the fish at high speed.
  • the addition of gas bubbles to this injection water flow results in a mixture that has been found to have a favourable effect on the removal of the multicellular ectoparasites, such that they are more easily dislodged by the water flow from the ejector nozzle of the ejector device.
  • the pressure in the gas bubbles is determined by the pressure from the vertical water column between the top point of the main duct and the vertical level at which the gas bubbles are located.
  • the gas bubbles will grow as the pressure in the liquid drops.
  • the specific gravity of the water/gas mixture in the main duct becomes smaller as it goes up to the top point of the transport pipe, such that the velocity of the water flow increases if the energy input from the ejector device is constant.
  • the specific gravity/pressure ratio as described above will be reversed.
  • the specific gravity and the pressure of the water/gas mixture will increase in the direction of the outlet of the main duct.
  • the fish are flushed by the cleaning water flow/injection water flow that is directed towards the fish in the main water flow in the main duct.
  • the flushing is found to be more effective for removing the multicellular ectoparasites from the skin of the fish.
  • the water velocity in the cleaning water flow/injection flow is estimated to decrease in inverse potential proportion to the distance from the ejector nozzle, because water from the main flow is mixed into the cleaning water flow. This water is accelerated at the expense of the velocity of the cleaning water flow.
  • the ejector device is configured with a nozzle construction as described above, the water jet will look like the wall of a funnel. The wall of this "funnel" will be thinnest, have highest velocity and be most effective closest to the ejector nozzle.
  • this form carries with it gas or water particles from the medium surrounding it.
  • the particles are given a direction towards the apex of the conical form.
  • the water flow from ejector nozzle that surrounds the base circle of the cone thus is, at the outset, on course for the apex of the cone.
  • a local negative pressure arises from the top of the cone and down towards the ejector nozzle at the base circle of the cone. The estimated pressure fall will initiate a particle flow that goes in the opposite direction to the particle flow that is held in motion at the outer surface of the conical form.

  • the multicellular ectoparasites that are flushed off the fish must be collected otherwise they will attach themselves to other fish. After the multicellular ectoparasites have been dislodged from the fish, they are carried onwards in the water flow through the transport pipe together with the fish.

  • a pressure drop occurs in the water flow containing the fish and the multicellular ectoparasites, when the water flow is passed over into the outlet chamber, the reason for this being that the outlet chamber has a cross- section that is larger than the cross-section of the transport pipe.
  • the water flow containing the multicellular ectoparasites and the fish meet the water that fills the side opening. Because the water flow has a certain velocity, and a pressure drop occurs in the water flow when it reaches the outlet chamber with the enlarged cross- section, the water in the side opening is accelerated in the same direction as the direction of travel of the main flow and water flows in through this side opening.
  • a screen is secured oriented at an angle across the direction of travel of the main water flow, so that the elements that are too large to pass through the screen are led out in counterflow through the side opening.
