    Hydraulic lamellae against pressure water injection in total flood conditions. By injecting a stream of water, at a certain pressure and flow rate, a certain amount of energy is provided in a higher inlet of said channel. The lamellae being open channels in their upper and lower part, by the principle of "conservation of the amount of movement", a flow is induced inside, capturing the effluent from its upper part, and expelling it from its lower part. Likewise, the injection of the effluent will generate a great turbulence that will travel inside the canal at the speed generated due to the energy provided. Thanks, again, to the conditions of total flooding, the effect of gravity is annulled, and therefore, all the turbulence generated will go through the lamellae, effectively dragging the solids deposited on all its interior surfaces, regardless of the inclination from the lamellar canals, and expelling the solids from the bottom towards the base of the tank, where they will be evacuated.
    The incorporation of the submersible pump mounted on the frame is essential for the proper functioning of the cleaning system, since it provides the system with a constructive simplicity that is beyond the reach of any alternative that does not incorporate a submersible pump mounted on the frame. DESCRIPTION OF THE DRAWINGS
    To complement the description that is being made and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical implementation thereof, a set of drawings is attached as an integral part of said description. where, for illustrative and non-limiting purposes, the following has been represented:
    Figure 1.- Shows a schematic perspective view of the system of the invention mounted on a lamellar decanter.
    Figure 2.- Shows an enlarged detail view of Figure 1 where, for a greater definition of the automatic cleaning system, some elements of the tank have not been represented.
    Figure 3.- Shows an enlarged perspective view of a detail of the frame.


    Figure 4.- Shows a perspective view where the power supply of the submersible pump is detailed. PREFERRED EMBODIMENT OF THE INVENTION
    Next, a detailed description of a preferred embodiment of the present invention is provided with the help of the accompanying Figures 1-4.
    Figure 1 shows a lamellar decanter (1), to purify wastewater or effluent, by decanting the solids contained in the water or effluent. The decanter (1) comprises a tank (2) which, in the embodiment shown in Figure 1, has a rectangular section, with a base (3), an open upper area (4), and side walls (5). The wastewater, or the effluent, access the decanter (1) through one or several lower inlets (32) located in the bottom of the tank (2), in the side walls (5). Also, purified water, at least partially free of solids, leaves the tank (2) through collection channels (6) located on the walls (5). The collection channels (6) are supported by a support structure (25).
    Inside the tank (2), at an intermediate height above the base (3), and occupying as much of the tank section as possible (2), modules (7) are submerged in the effluent and formed by lamellae ( 8). The lamellae (8) constitute ducts, generally elongated and of quadrangular section (although it can also be circular or other shapes), provided with lateral faces (9), an upper mouth (33) and a lower mouth (34), the modules (7) of lamellae (8) being designed to collect residual water from below, so that the residual water enters the lamellae (8) from below, through the lower mouths (34), and therefore , running said lamellae (8) upwards, until they exit through the upper mouths (33), while the solids contained in the wastewater are deposited in the lower part of the faces (9) of the lamellae (8), where they are grouped and descend forming a reverse flow that is directed by gravity towards the base (3) of the tank (2), from where they are subsequently removed. The lamellae (8) are arranged with an inclination on the horizontal, which is preferably between 50 ° and 60 °.

    submersible pump (16) to all solenoid valves (21) corresponding to the same direction. When a displacement in one direction is desired, the nozzles (18) oriented in the opposite direction will generate a jet for a certain time and therefore a horizontal thrust moving the frame (13) in the desired direction and the desired distance. The solenoid valves (21) are open for the time necessary to move the frame (13) a predetermined distance, for example, between 20 and 30 mm. When the solenoid valve (21) is closed again, and the frame (13) and, therefore, also the injection manifold (14), in a new position, all the flow provided by the submersible pump (16) returns to the nozzles (15), to inject water into the lamellae (8). The frame (13) will remain in this new position for a predetermined time, to allow time for generated turbulence to eliminate the solids deposited inside, until the solenoid valve (21) is opened again for the next movement.
    The described solution corresponds to a particularly convenient preferred example, although the displacement of the frame (13) can be achieved using other alternative means, such as, for example, traction system by motor-reducer and cable or chain, at sufficiently low speed .
    On the other hand, for other tank configurations (2) other than the described rectangular configuration, adaptations of the displacement means (17) can be devised, depending on the particular configuration adopted by the tank (2). By way of illustrative example, in the case of the cylindrical tank (2) mentioned above, the guide means (11) can be circular, so that the displacement of the injection manifold (14) would not necessarily be one-way and back, although it would be possible, although a circular displacement is preferred, radially sweeping the inside of the tank (2), so that, optionally, the nozzles (18), corresponding to the direction of return, as well as their solenoid valve
    (21) associated.
    Since each nozzle (15) generates on the frame (13), due to the effect of action and reaction, an upward thrust due to the flow and pressure generated, the arrangement of ballasts (22), preferably mounted on the injection manifold, is provided (14). In this way, the weight of the frame (13) and the elements mounted therein, including the ballasts (22), in immersion conditions, will tend to compensate for the thrust in order to achieve a balance.

    unlikely.
    The advantages that derive from the operation and conception of the system are therefore:
    -Efficient cleaning of the entire interior surface of each and every one of the lamellae (8) installed.
    - It is not necessary to empty the tank (2) to proceed to cleaning.
    -  It will not be necessary to stop the decantation process since the solids are removed by the lower part of the lamellae (8) and in the direction of the base (3) of the tank (2), from where they are evacuated.
    -  The solids removed during the cleaning process are evacuated from the modules (7) of lamellae
    (8) by its lower part and towards the bottom of the tank (2), where its extraction will take place. Therefore, no solids will remain on the existing surfaces above the modules (7), which would affect the quality of the effluent.
    -It is not necessary the presence of operators during cleaning.
    -Because of the low operating cost of the system, and the no need to stop the decanting process, cleaning can be carried out with the desired frequency, keeping the decantation installation in optimal conditions and therefore maintaining its maximum efficiency.
    - When installed above the lamellae (8), its installation is simple and cheap, being also accessible in case of possible corrective or maintenance actions.
    -The displacement means (17) by means of propulsion eliminates the need for other traction means, substantially simplifying its installation and reducing its cost, especially in tanks (2) between 10 and 150 meters long.
    - The only connection required by the system described is the power cable (29) for the submersible pump (16) and the solenoid valves (21).


    -The possibility of overloading by adhered solids in the modules (7) and their supports (10) is avoided, which prevents a collapse of the installation in case of emptying. This also makes it possible to size the supports (10) considering only the weight of the modules (7) and, therefore, reducing the installation costs.
