    Deposit sweeping device. OBJECT OF THE INVENTION
    The present specification defines a tank sweeping device that removes turbines or sludges from the bottom of a tank or tank by means of a scraper and the help of a pump in such a way that it is achieved that oil, wine or liquid products, and the residue is in the minimum possible time in contact and therefore the transfer of aromas or unwanted substances is reduced. In turn, the present device allows to be manually operated and manipulated by an operator from outside. The field of application of the invention is the sector related to food liquids, and in particular it is intended for the oil and wine production sector. BACKGROUND
    In the sector of the storage of liquid substances in tanks or tanks, the existence of various cleaning elements or mixers is known, this idea or devices being mainly established in the processes of cleaning waste water tanks.
    In this type of deposits there is a sedimentation of the suspended solids from the biological treatment of urban and industrial wastewater, and in these cases inside the tank a device is introduced that breaks the possible foam produced in the production process of sludge retaining the floats present to prevent them from going out with purified water.
    In general, in this typology of devices a central vertical reinforcement is concentrically placed in the tank and in its middle or lower part it has fins or rakes that rotate in solidarity with the central axis so that it maintains the


    continuous movement of wastewater inside. There is a great diversity of examples of this specific typology of devices, among which we highlight the ES0453192 register of Dorr-Oliver Incorporated, the register ES2399739 of Angel Luis Ibañez Muñoz or the register EP2521610 of Invent Umwelt-Und Verfahrenstechnik, which all keep this premise basic and have implementations in the area either of the fins or of the vertical structure.
    There are also other types of devices that incorporate a plurality of injectors in said lower part as defined in the register ES8604474 of Alsthom-Atlantique; or also having a central frame as a structure, have blades on said vertical axis as defined in the EP1648843 register of Syndicat Intercommunal; others that, for example, have a stirring device formed by a blade with a vertical helocoidal shape as defined in the EP1123731 register of Ekato Solidmix GmbH; or finally devices and apparatus for cleaning more complex deposits such as those that store oil, which as defined in the EP1106269 register are based on the circulation of the stored product.
    All these cases have the same disadvantage in common, that although it is true that they agitate and are intended to prevent suspended solids within the liquid mass from decanting, the cleaning of said decanted solids or adhered sludge requires that they be emptied and then cleaned by the direct application of pressurized water on the internal walls of said tanks or tanks.
    As an alternative to these devices that do not solve the problem of cleaning, the present invention arises, first because it presents a solution that is adaptable to a specific type of tanks or tanks, which are those of food liquid and specifically oil and wine deposits, whose cleaning was based on lower taps where to eliminate impurities, such as defined in the register ES1113056U, and / or with a cleaning of the walls and bottom of the tank once it was empty and by water under pressure, because it has a solution that also allows an optimal performance of said liquid food product in its storage time, and finally because it presents a solution that allows it to be used manually by an operator whenever he wishes, and therefore its mechanism and implantation in the tank is cheap and simple and can be installed


    in any type of deposit whose bottom is a flat surface, even being able
    or not have a certain inclination.
    That is why it is considered that the present invention constitutes a solution that differs from the configuration and characteristics of any type of sweeping device of the deposit bottom, either for the cleaning of the deposit itself, of the prevention of precipitation of solids or of the agitation of the liquid contained in the tank, and therefore a totally innovative solution is introduced in the sector that allows to locate a sweeping device at the bottom of any type of tank or tank whose base is a flat, even having or not having some inclination DESCRIPTION OF THE INVENTION
    The present invention defines a deposit sweeping device, in particular the bottom of said deposits when they have a flat surface although this surface may have a certain inclination with respect to the base of the tank itself. It should also be noted that the present invention is intended for the preferential storage of food liquids and in particular its main objective is to be installed in oil and wine tanks.
    For this, the invention is based on a structure formed by four radial arms that start from the center of the tank every 90º and in which in one of those arms is located the bottom scraper element that at the same time scratches the suction bottom the dirt or solids that may be in said bottom, and from which center a suction pipe with said dirt or solids, such that the assembly sweeps and cleans the bottom of the tank of dirt. In this sense it is important to note that this sweeping device is manually manipulated from the outside thanks to a magnet system, for which each arm has a support with a magnet that contacts the tank wall, and from the part outside the tank an operator with another magnet displaces said arm 90 °, so repeating this operation several times covers the entire surface and diameter of the tank.


    Going into more detail, the structure formed by four arms is located in the lower and inner part of the tank. As anticipated, the four arms are split from the center of the tank and rest on a central base with a bearing that allows the rotation of said structure. One of the arms is the scraper element, which among other elements that will be defined later has a magnet at its end, while the other three arms are tubes whose mission is to support a magnet at its end in contact with the tank wall. The main mission of this radial configuration is that an operator from the outside by means of a handle with an external magnet can slide said handle every 90º, repeating this operation as many times as necessary, so that the structure and the scraper element can clean the 360º. The location of these magnets every 90º responds to the fact that in this way it is only necessary to draw or indicate the initial location and the path of the magnet on that surface and therefore there is no problem with possible external bodies that interfere the path of the magnet in its entire diameter , since it is only necessary to leave that circumference room free of obstacles outside.
    If we go into the detail of the scraper element, it must be said that it occupies the length equivalent to the radius of the circumference that the base of the deposit occupies in plan. This scraper element is a hollow rectangular linear and tubular element. The section of this scraper element is not continuous, but decreases from the center of the tank towards the end in contact with the wall of the tank, that is, that the quadrangular section is larger in the central area of the tank and is smaller at the end in contact with the tank wall. This scraper element has a series of particularities that allow it to achieve the objective for which it is designed, which is on the one hand the scraping or sweeping the bottom, for which it has scraper plates in contact with the bottom, and on the other hand that of cleaning or suctioning the solids and waste deposited at the bottom for which there are suction grooves on the underside of the scraper element that suck said solids and are sucked outwards by means of a suction pipe connected to a outside pump The mechanism of sweeping, cleaning and aspiration of the waste or solids located in the bottom is the one that the operator from the outside by means of the magnet support makes move the scraper element, which by means of its scraper plates lifts the solids of the bottom, the


    which are suctioned by the grooves of aspiration and extracted to the outside thanks to the suction pipe.
    In this sense it should be noted that the scraper plates, which are like sloping skirts, are placed on the front face of the scraper element and there are a plurality of them depending on the number of the arm length. These scraper plates have a minimum separation between them so that the angular displacement is more favorable and there is less friction to the advance on the part of the liquid, and because in that way in case of breakage or need of maintenance this is easier to repair, and they are fixed to the front face by means of hinges. A series of fixed counterweights is also provided on the front face, whose function is that the scrapers maintain their position and ensure contact with the bottom. Similarly, on the rear face of the scraper element, inclined flaps can be located that make the solids raised in the surface scraping process be maintained in the suction zone and precisely aspirated by the lower grooving.
    Following this last argument, a series of suction grooves are located on the face or lower wall of the scraper element, which have a minimal separation between them as nerves such that said suction surface is not continuous, and of this In this way, this total suction surface is more resistant against the possible turbulence generated by the arm movement and the solids raised by the scraping skirts. It should be noted that the section of said grooves is also variable, and is decreasing as it approaches the end in contact with the wall, that is, that the suction grooves have a larger suction surface in the central area of the tank and less in the area from the end
    As anticipated at the beginning of the description, the scraper element is linear and has a rectangular and hollow tubular configuration. This last fact is very important, because being hollow allows the conduction of the solids sucked outwards. For this, the scraper element connects in its central part with a hollow bearing that is in contact with a fixed suction pipe connected to an external pump that sucks said solids and expels them to the outside. As just said, the scraper element in the center is connected with a bearing


    hollow so that said bearing also allows the rotation of the structure of the four arms and in turn this bearing with the fixed pipe anchored on the outside gives stability to the whole sweeping device.
    In order to facilitate the movement of the structure, at least one wheel is disposed in the arm of the scraper element, located at the end in contact with the tank wall. This wheel fixes the structure and the guide so that the circular movement is correct. As mentioned, this wheel can also be located in the rest of the arms of the structure.
    Finally, it should be noted that the support of the magnet that each of the arms has is composed of a plate from which a rod with a magnet included in a bushing with a nylon plug emerges. In order to adjust the magnet against the wall of the tank, on the rod there is a spring to adjust said position against the wall.
    The materials used for the different elements that make up the whole of the tank sweeping device can be variable, as long as they do not affect the properties of the food liquid, therefore they can be of a plastic, metallic coated or steel nature.
    In order to complete the description that is being made and in order to help a better understanding of the characteristics of the invention, a set of drawings is attached as an integral part thereof, where the following has been represented as an illustrative and non-limiting nature:
    Figure 1 is a free perspective representation of the sweeping device inside a tank.
    Figure 2 is a plan representation of the sweeping device.
    Figure 3 is a free perspective representation of the scraper element located in one of the arms of the sweeping device of the previous figures.
    Figure 4 is a representation of the lower part of the scraper element.
    Figure 5 is a representation of the detail of a cross-section in the scraper element of the previous figure.

    Description of the drawings
    In Figure 1 the whole sweeping device can be observed inside a tank, and in particular it can be seen how said device is usable in flat bottom tanks and with a slight or certain constant inclination in them. In the present figure it can be seen how the sweeping device is located in the lower and inner zone of the tank and composed of a structure formed by four arms (10) located radially with respect to the center of the tank, and as one of them is located which is called the scraper element (1) which is responsible for both scraping the surface of the bottom of the tank and sucking and vacuuming the decanted solids or waste that could be in said soil. This scraper element (1) is connected to a suction pipe (2) that expels said waste to the outside by the action of a pump. The invention is designed so that the structure has a rotating movement with respect to its center, therefore a central base (6) with bearings is available that allows the rotation of said structure, as in the connection between the scraper element and the Suction pipe is placed a hollow bearing (5) that also allows the structure to rotate. In this sense, and although it is not seen in the figure, the central base (6) is preferably composed of an outer ferrule made of stainless material which in turn houses an inner nylon ferrule with a connecting rod with the structure of material a turn stainless.
    As also noted in this first figure, three of the four arms (10) have the function of incorporating at their end in contact with the wall a support
    (30) that has a magnet attached (3); while the fourth arm has the function of the scraper element (1) previously defined. This radial configuration has the function that an operator from the outside by means of a handle (4) with a magnet can slide said handle every 90º, repeating this operation as many times as necessary, so that the structure and the scraper element ( 1) can clean the 360º. In this sense, and in order to guide the movement of the scraper element (1) and of the whole structure, at least at one end of one of the arms, and preferably in that of the scraper element (1) a wheel is incorporated (not referenced in this drawing) in contact with the bottom that improves and ensures the operation and rotation of the assembly.


    Figure 2 is a plan view of the sweeping device of the first figure inside the tank, in which the radial configuration of the structure with its arms (10) and scraper element (1) can be clearly seen that starting from the center of the tank , and by means of external movements of 90º thanks to the location of its magnets (3) at the ends of the arms, it can cover and treat the floor of the tank in its 360º. It should be noted as in this figure if the wheel (7) is represented, which, as previously mentioned, is at least located at the end of one of its arms and preferably at the end of the scraper element (1), and can be observed in this figure shows the need for a hollow bearing (5) that connects the scraper element (1) with the suction pipe
    (2) and in turn allow the structure to rotate.
    On the other hand, and taking into account the previous figures, in Figure 3 the different elements that make up the scraper element (1) can be observed in greater detail. First, it should be noted that the scraper element (1) is a hollow rectangular linear and tubular element (100). Also as previously advanced, the scraper element (1) has the objective of scraping or sweeping the bottom, for which it has a plurality of scraper plates (11) located on the front face and fixed to said face by means of hinges (12), such that said flaps that are in the form of a skirt are in contact with the bottom and therefore scrape the bottom; and on the other hand it has the objective of sucking or extracting the solids raised by scraping for which it has grooves (not referenced in this figure) of suction in its lower face. As can be seen in this Figure 3, the scraper plates (11) are like inclined skirts and are placed on the front face of the scraper element. The number of plates (11) is variable depending on the number of the arm length. In order to improve and ensure the position of these plates, they are also located on the front face of a series of counterweights (13). Similarly, inclined flaps (not shown in the present figure) can be located on the rear face of the scraper element so that the solids raised in the surface scraping process are kept in the suction zone and precisely aspirated by lower grooving


    An important detail of the invention and which can be seen in this Figure 3 is that the support (30) of the magnet located at the end of each of the arms of the structure, and in the case of the present figure at the end of the scraper element (1), is defined by a plate or support from which a rod (32) emerges with a magnet (3) included in a bushing with a nylon plug. Face to adjust the magnet (3) against the wall of the tank and thus the operator can move the handle (4) with the outer magnet 90º, on the rod (32) there is a spring (31) to adjust the position of the magnet ( 3) against the wall. On the other hand, this figure also shows how a previously defined wheel (7) is located at the same end.
    Following the technical arguments of the previous figure, Figure 4 represents a bottom view of the scraper element (1), in which it can be seen how on the face or bottom wall of the scraper element a series of grooves (14) of aspiration, located linearly, which have a minimum separation between them by way of nerves such that said suction surface is not continuous, and in this way, that total suction surface is more resistant against the possible turbulences generated by the arm movement and solids lifted by scraper plates (11). It is necessary to define that, as can be seen in the figure, the section of this scraper element (1) is not continuous, but decreases from the center of the tank towards the end in contact with the wall of the tank, just like the The grooves section (14) is also variable, and is decreasing as it approaches the end in contact with the wall, that is, the suction grooves have a larger suction surface in the central area of the tank and smaller in the area of the extreme. This gradual change of section favors the suction of solids and aspirated waste. Finally, this figure shows the location at the end of both the magnet (3) and the wheel (7).
    Finally, Figure 5 represents a detail of a cross-section made to the scraper element (1), in which it is observed as a hollow rectangular linear and tubular element (100), in whose lower face it has the grooves (14) through which the solids or substances scraped by the scraper plate (11) located on the front face and held therein by the hinges (12) are sucked and sucked. In addition, it will be observed how the counterweights (13), also located on the front face, ensure the correct position of the scraper plates (11) and ensure that before a


    problem return to its contact position with the floor or bottom of the tank. On the other hand, it is observed how the magnet (3) is located at the end and is in contact with the wall of the tank, just as it can be seen as the wheel (7), which as seen before is at least in one of the arms and preferably in that of the scraper element (1), it is in contact with the ground and allows to improve the displacement of the whole structure and in turn allows to ensure a minimum height necessary for the aspiration zone to be generated as it progresses the scraper element (1).
    Described sufficiently in what precedes the nature of the invention, taking into account that the terms that have been drafted in this specification should be taken in a broad and non-limiting sense, as well as the description of how to put it into practice, and, demonstrating which constitutes a positive technical advance, which is why the registration of the present invention is requested, being what constitutes the essence of said invention what is specified in the following claims.
