Definitions
- the present invention refers to a device in an oxygen supplying unit into a volume of water and which is located in the water and cooperates with a pump, an injector and an intake air device, which together produce a mixture of water and air that oxygenates and agitates the water.
- oxygen supplying structures consist of several oxygen supplying units connected to each other to feed air to a volume of water e.g. a watercourse, a lake, a basin, a tank or similar, so that oxygen essential for life is added to the organisms living in said volume of water. All these oxygen supplying units add air through intake air devices, operated with positive pressure from compressors, located above the surface of the water. If it is needed to oxygenate greater volumes of water in a larger area the air is supplied to several oxygen supplying units at the same time and water is supplied in separate water pipes, which makes it necessary to connect a net of hoses and pipes to each oxygen supplying unit.
- One object of the present invention is to eliminate the disadvantages of above mentioned structures and to simplify and cheapen the production, use and maintenance of these. Thanks to the present invention a simple oxygen supplying unit has been produced, a unit mixing air and water into an air- water mixture which is pressed through an injector on a predetermined depth preferably close to the bottom, where the amount or volume of water to be oxygenated and agitated is located.
- air or oxygen is obtained from above the water surface through an air intake preferably consisting of a hose or a pipe.
- the air intake is connected to a pump placed close to the bottom where it also draws in water that is mixed with air and where it is also connected to an injector.
- an anchorage unit preferably a floating arrangement consisting of a landing stage, a buoy, a boat or similar and together it forms an oxygen supplying unit.
- This unit is in a short time easily moved to any chosen place and there is no need for any special installation, which also makes it easy to supply with current through a cable which is attached to the pump through the air intake, said cable always moves together with the unit. It is therefore only the cable that has to be connected and no water pipes or air compressors are needed.
- water is drawn into the pump directly from the volume of water preferably close to the bottom and is thereafter pressed into the injector.
- the motion of the water in the injector automatically draws in air from the air intake and the water and air are mixed in the injector.
- the pressure established in the pump against the now drawn in water-air mixture presses it out into the water volume, which is to be oxygenated and agitated.
- the injector ejects the water-air mixture with such a force that air bubbles and water agitate the surrounding amount of water so that mud, sediment and other particles are moved around and made accessible for oxygenation which makes marsh gas and bad smell disappear at the same time as the vital oxygenation takes place without hurting living organisms such as fish and crawfish in piscicultures.
- a swimming particles strainer is fitted to the inlet of the pump, which prevents the clogging of the oxygen supplying unit by gravel, mud and stones.
- the air bubbles are smaller at the beginning depending on the water pressure being higher at the bottom than closer to the surface, enabling them to agitate small particles at the bottom to get an effective oxygenation.
- the greatest advantages of the invention therefore is that it is simple and cheap to manufacture, install, handle and maintain and is therefore suitable for the oxygenation of small volumes of water such as aquariums as well as greater volumes of water such as big basins and pools, lakes and similar. This is made possible through the use of number of oxygen supplying units necessary, each of which is working independently but together form a flexible and complete oxygen supplying unit which during the oxygenation work easily may be adapted to the prevailing circumstances, since each oxygen supplying unit is separately movable.
- Figure 1 shows a schematic view of an oxygen supplying unit placed in a volume of water, which is to be oxygenated and
- Figure 2 shows a schematic section of the connection of the pump to the injector.
- an oxygen supplying unit 1 is mainly submerged into a volume of water 15 below a surface of water 19, said oxygen supplying unit comprises an anchorage unit 2 such as a landing-stage or a quay. It can also be a floating device 20 such as a boat, a buoy or similar which is easily movable.
- an air intake 3 is connected, which may be in the form of a hose, a pipe or similar and adjustably connected, so that it when needed may be adjusted in the directions 13, 14 upwards and downwards.
- an injector 5 and a pump 6 are attached, said pump 6 is powered by a cable 7.
- the air intake 3 draws in air 9, as the pump 6 draws in water 10 through a strainer 11 fitted to a water intake on the pump 6.
- the air 9 and the water 10 are mixed in the injector 5 and this water- air mixture 17 is pressed out through a nozzle 12 at the injector 5 in a pre-set distance 16 from the bottom 4, said distance 16 is adjustable in the directions 13,14.
- the air- water mixture 17 agitates the volume of water 15, so that mud, particles, sand and gravel are put in motion and water bubbles 18 coming out of the nozzle 12 oxygenate the volume of water 15.
- an ejection device 21 is fitted to the pump 6, which discharges into a connection place 22 of the air intake 3, where the water 10 and the air 9 are mixed in the injector 5.
- the length 23 of the ejection device 21 is kept as short as possible to minimise the friction of the water against the ejection device 21 to keep energy consumption as low as possible, when the pump 6 is pumping water into the injector 5.
- the invention can of course be used by powering the pump 6 with some other kind of energy than electricity.
