    The present invention relates to a method and an apparatus for gathering valuable substances, such as uranium, gold, silver or the like from sea water. The features characterizing the invention are that the sea waves are caused, by using the energy thereof, to rush up a ramp (2) which leads the waves into a basin from above, which thereby is filled to a level (By) higher than the external stillwater surface (Ly), the water quantity within the level difference ( DELTA H) applying a hydrostatic pressure which brings the water in the basin to flow through one or several layers of filters (4) containing sorbing, ion-exchanging or bioactive mass, whereafter the water is directed back to the sea on a level lower than the upper edge of the ramp (2).

    g. The invention relates to an apparatus for collecting valuable substances such as uranium, gold, silver, etc. from seawater. A device for collecting substances, mainly uranium, silver gold from seawater, known to protrude above the surface of seawater is known. A rectangular-shaped baseline, one of the long walls of which is located opposite the sea waves, one or several layers of filters containing a sorbing, ion-exchange or bioactive mass and connected to the basin, and devices with openings for water inlet and outlet. In this device, water flows through the layers of filters due to the difference in water level during tides ij. A disadvantage of the known device is the low efficiency of the process due to the fact that the energy of the sea waves is not fully utilized. The aim of the invention is to increase the efficiency of the process. This goal is achieved by the fact that, in a device for collecting substances, mainly uranium, gold, silver from seawater, including a basin of a rectangular shape protruding above the surface of seawater, one of the long walls of which is located opposite to the sea wave one or more layers of filters containing sorbent, ion-exchange or bioactive mass and connected to the pool, and devices with openings for water inlet and outlet, the pool wall, located opposite to the sea waves, is provided with an inclined plate, and STI for input and output of water formed below the upper edge of the inclined plane. It is advisable that the pool was equipped with pontoons. It is also advisable that the inclined plate be installed with the possibility of changing the angle of inclination and / or with the possibility of vertical movement. The proposed invention makes it possible to efficiently use the energy of sea waves. In accordance with the performed methods, located on a pontoon basin having an inclined plane that is sloped at its upper part, will lift approximately 3 m of water per second by one meter length to a height of about 2 m in the basin. to have 300 meters per second 2 meters above the water outlet holes. In the proposed device, the sea waves roll onto an inclined plane, which guides the waves into the pool from above, and the water under the action of hydrostatic pressure flows through one or more filter layers containing a sorbent, ion-exchange or bioactive mass, after which the water returns to the sea at a lower, than the upper edge of the inclined plane. FIG. 1 schematically shows the proposed device, the cross section; in fig. 2 - the same, another option. The device for collecting substances from seawater (Fig. 1) has the shape of an oblong, open-top basin 1. On one wall of basin 1, an inclined plane 2 is provided, the upper surface of which is inclined at the upper edge of the pool so that the sea waves 3 are directed to the pool. The height of the inclined plane 2, as well as its angle of inclination relative to the surface of calm water B, are adjusted to optimize the flow of water into basin 1 depending on the actual wave height. With relatively small waves, a second inclined plane 4 may be provided for lifting wave 3 before it meets and breaks against inclined plane 2 in order to throw it over the edge into the pool. The pool should be located so that the waves flow normally to the side of pool 1, provided with an inclined plane, for the greatest possible length. In the lower part of the basin 1, several layers of filters 5 are located one above the other (in Figure 1 four layers are shown that are filled with a mass suitable for collecting the necessary substance, for example, titanium dioxide hydrate for sorbing uranium, an ion-exchange mass or a bioactive mass) . Each filter layer has inlet valves 6, which can be arranged in such a way that water flows from zone A of pool 1 either from top to bottom or from bottom to top through the corresponding filter layer and then returns back to sea through outlet valves 7 and check valves 8, located on the leeward wall of the pool 1. In accordance with the invention, the water level B in the pool is higher than the outside level B of calm water using wave energy to fill pool 1 with seawater. The amount of water corresponding to the difference in UH levels creates a hydrostatic pressure that causes water to flow through the filters 5. Soils, such as oil, hard floating and suspended particles or similar substances that fall with the sea waves into basin 1, can be removed using a scraper 9 or similar device. In addition, a tank 10 containing substances that kill microorganisms is located at the bottom of the basin. These substances are periodically supplied to the filters 5 by means of a pump 11, after which they can step back into the tank 10 when the output valves 7 are triggered. The elution, i.e. the extraction of the substance retained by the filters 5, for example uranium, is carried out, if necessary, with an eluting fluid, for example sulfuric acid or a carbonate solution, which is stored in another tank 12. The eluting fluid is pumped to the filters1 5 using a pump 13 and a median tube 14. The elution liquid and the extracted material are then collected in the tank 12. The substance can then be removed from the elution liquid before being sent to the Forest / Concentrate for further processing, for example imer, organic ion exchangers. The proposed device (Fig. 1) is primarily intended to be indigenous to the sea at a place of strong sea current. Pool 1 is installed on pontoon bases (not shown) by which the height of the pool can be controlled. In another case, basin 1 may be stationary on the ground along a suitable coast. Although it may be difficult for corroding at sea, it has the advantage of continuously flowing new water, which has a good effect on the operation of filter masses. When the pool is located on the shore, the same water tends to move back and forth, so that it is quickly drained. In order to be technically viable, pool 1 must be relatively large. For example, it can be noted that the length of the basin, normal to the direction of movement of the waves, may be in the order of 50 to 200 m, its width from one long wall to the other will be about 20-50 m, and the depth may be about 10- 40 m. In another embodiment of the device (Fig. 2), the pool rests on pontoon bodies 15, containing air filled chambers 16 and ballast tanks 17 for controlling the vertical and horizontal position of pool 1. At the outlet openings from pool 1, it is possible to dispense with non-return valves. In addition, in this embodiment, in the pool, filters 5 are arranged vertically, so that water flows horizontally through filters 5 through inlet valves 6. When the inlet b and outlet 7 valves change, the filters can be returned by a backflow from contamination or a similar substance. In the output channel, valves 18 and 19 are provided, by means of which water flowing out of filters 5 can be directed back to the sea, or vice versa, the liquid that kills microorganisms and the depleting liquid, respectively, can be directed to their respective tanks, where they are stored. The fluids are made using pumps 20 and 21 in the manner described for the first embodiment of the device. The design and composition of the filter elements can be changed so as to obtain the best possible exchange when collecting the necessary substances. In addition, you can conclude filters 5 in;:. camera separated from. basin 1 and connected to it through hatches or similar devices, which creates advantages in terms of service. The consumption of the elution liquid and the washing liquid is additionally limited. Then the pipes 14 are connected directly to the filters. Thus, in the proposed device, it is possible to use the energy of sea waves to collect valuable substances from water. 3 in.
