Estado de la técnica anteriorState of the prior art
Actualmente son conocidos en el estado de la técnica diferentes tipos de filtros para líquidos, entre los que cabe diferenciar: los filtros de agua con recipiente de poliéster reforzado con fibra de vidrio y una superficie de filtración correspondiente con su área o sección útil, filtros de acero con un medio filtrante regenerativo de perlita, y los filtros de poliéster reforzado con fibra de vidrio (PRFV) con medio filtrante regenerativo de perlita tales como los descritos en las solicitudes de patente WO2018211161A1 y WO2022101528A1, del mismo titular de la presente invención. Currently, different types of liquid filters are known in the state of the art, among which the following can be distinguished: water filters with a fiberglass-reinforced polyester container and a filtration surface corresponding to its useful area or section, steel filters with a regenerative perlite filter medium, and fiberglass-reinforced polyester (PRFV) filters with a regenerative perlite filter medium such as those described in patent applications WO2018211161A1 and WO2022101528A1, by the same holder of the present invention.
El documento WO2022101528A1, considerado el más próximo a la presente invención, describe un sistema de filtración de líquidos, que comprende un depósito de filtración provisto de un techo o placa separadora que divide el interior del mismo en un compartimento inferior y un compartimento superior; un conducto de entrada del líquido a filtrar hacia una zona próxima a la pared inferior de dicho depósito; una pluralidad de latiguillos que sobresalen del techo o placa separadora hacia el compartimento inferior; comprendiendo dichos latiguillos una superficie exterior que conforma un soporte de un medio filtrante y una superficie interior que define un conducto de circulación del líquido filtrado, cerrado por el extremo inferior y abierto por el extremo superior, hacia el compartimento superior; un conducto de salida del agua filtrada por la zona superior del depósito; un circuito de regeneración del medio filtrante; un circuito de auto limpieza del filtro y un panel de control. Document WO2022101528A1, considered to be the closest to the present invention, describes a liquid filtration system, comprising a filtration tank provided with a roof or separator plate that divides the interior thereof into a lower compartment and an upper compartment; an inlet conduit for the liquid to be filtered towards an area close to the lower wall of said tank; a plurality of hoses that protrude from the roof or separator plate towards the lower compartment; said hoses comprising an outer surface that forms a support for a filter medium and an inner surface that defines a circulation conduit for the filtered liquid, closed at the lower end and open at the upper end, towards the upper compartment; an outlet conduit for the filtered water through the upper area of the tank; a regeneration circuit for the filter medium; a self-cleaning circuit for the filter and a control panel.
El sistema de filtración de líquidos del documento WO2022101528A1 incorpora unas características orientadas a mejorar el funcionamiento del sistema de filtrado del documento anterior WO2018211161A1, concretamente a evitar la entrada descontrolada y violenta del líquido a filtrar desde la boca de entrada hacia los latiguillos, lo que puede provocar que el material filtrante de perlita se desprenda de la superficie exterior de los latiguillos, anulando o reduciendo excesivamente la capacidad de filtración del sistema. The liquid filtration system of document WO2022101528A1 incorporates features aimed at improving the operation of the filtration system of the previous document WO2018211161A1, specifically to prevent the uncontrolled and violent entry of the liquid to be filtered from the inlet into the hoses, which can cause the perlite filter material to come loose from the outer surface of the hoses, nullifying or excessively reducing the filtration capacity of the system.
Para ello el sistema de filtración del documento WO2022101528A1 incorpora una placa distribuidora del líquido, dispuesta horizontalmente entre el conducto de entrada de líquido a filtrar y el extremo inferior de los latiguillos y que comprende una pluralidad de perforaciones de paso y distribución del líquido a filtrar hacia los latiguillos. For this purpose, the filtration system of document WO2022101528A1 incorporates a liquid distribution plate, arranged horizontally between the inlet conduit for the liquid to be filtered and the lower end of the hoses and comprising a plurality of perforations for the passage and distribution of the liquid to be filtered towards the hoses.
Durante el uso de este sistema de filtración el titular de la invención detectó algunos inconvenientes relacionados con la limpieza del filtro y la regeneración del medio filtrante. During the use of this filtration system the inventor detected some inconveniences related to the cleaning of the filter and the regeneration of the filter medium.
Un primer inconveniente está determinado por la acumulación en el extremo superior del compartimento inferior de grasas y materiales viscosos que en el caso del filtrado de agua procedente de piscinas están constituidos mayoritariamente por grasas y cremas solares, hidratantes o similares. A first drawback is determined by the accumulation at the upper end of the lower compartment of fats and viscous materials which, in the case of filtering water from swimming pools, are mainly made up of fats and sun creams, moisturisers or similar.
Durante la utilización del sistema de filtrado estas grasas se van acumulando por flotación debajo de la placa superior y entre los latiguillos, y cuando se introduce un caudal importante de aire presurizado en el depósito para realizar la regeneración del medio filtrante, este medio filtrante es presionado por aire ascendente contra la placa superior, formando junto con la grasa una costra que obtura una porción superior de los latiguillos. During use of the filtering system, these fats accumulate by flotation under the upper plate and between the hoses, and when a significant flow of pressurized air is introduced into the tank to regenerate the filter medium, this filter medium is pressed by ascending air against the upper plate, forming a crust together with the fat that blocks an upper portion of the hoses.
En estas condiciones el aire introducido en el compartimento inferior durante la regeneración del medio filtrante, se acumula en la zona superior de dicho compartimento y genera una sobrepresión que obliga al agua a pasar a través de la zona inferior de los latiguillos hacia el compartimento superior y a continuación hacia el exterior del depósito, lo que provoca que durante la regeneración del medio filtrante una parte importante del agua contenida en el depósito sea expulsada innecesariamente. Esta pérdida de agua provoca un descenso del nivel de agua que queda en el compartimento inferior, lo que impide que el agua alcance la costra acumulada debajo de la placa superior y entre la zona superior de los latiguillos, y que llegue a eliminarla, produciéndose una limpieza deficiente. Under these conditions, the air introduced into the lower compartment during the regeneration of the filter medium accumulates in the upper area of said compartment and generates an overpressure that forces the water to pass through the lower area of the hoses into the upper compartment and then out of the tank, which causes a significant part of the water contained in the tank to be expelled unnecessarily during the regeneration of the filter medium. This loss of water causes a drop in the level of water remaining in the lower compartment, which prevents the water from reaching the crust accumulated under the upper plate and between the upper area of the hoses, and from being removed, resulting in poor cleaning.
Un segundo inconveniente detectado es que durante la regeneración del medio filtrante, dicho medio filtrante se libera de los latiguillos y queda acumulado en unas zonas específicas que quedan resguardadas de las corrientes ascendentes de líquido y de aire, concretamente en una zona periférica de la placa inferior próxima a la pared lateral del depósito y en unas repisas definidas por las bocas de hombre situadas en la pared lateral del depósito, por lo que tampoco se consigue un regeneración completa del material filtrante. A second drawback detected is that during the regeneration of the filter medium, said filter medium is released from the hoses and remains accumulated in specific areas that are protected from the ascending currents of liquid and air, specifically in a peripheral area of the lower plate close to the side wall of the tank and on shelves defined by the manholes located on the side wall of the tank, which is why complete regeneration of the filter material is not achieved either.
Por tanto, el problema técnico que se plantea es el desarrollo de un sistema de filtrado de líquidos del tipo descrito anteriormente, que minimice la cantidad de agua desechada de forma indeseada durante la regeneración del medio filtrante; que consiga una limpieza efectiva del sistema de filtración, evitando que queden restos de suciedad fijados sobre superficie inferior de la placa superior y entre los latiguillos, y que realice una regeneración completa del medio filtrante. The technical problem that arises is therefore the development of a liquid filtration system of the type described above, which minimises the amount of water undesirably discharged during the regeneration of the filter medium; which achieves effective cleaning of the filtration system, preventing dirt residues from remaining fixed on the lower surface of the upper plate and between the hoses, and which carries out a complete regeneration of the filter medium.
Explicación de la invención.Explanation of the invention.
El sistema de filtrado de líquidos objeto de esta invención, siendo del tipo descrito en el documento WO2022101528A1 y en el preámbulo de la reivindicación principal de la invención, presenta unas características técnicas que resuelven la problemática expuesta anteriormente. The liquid filtration system object of this invention, being of the type described in document WO2022101528A1 and in the preamble of the main claim of the invention, has technical characteristics that solve the problem set out above.
Una de las características de invención es que el sistema de filtración comprende un tubo de evacuación del aire presurizado suministrado para la regeneración del medio filtrante, comprendiendo dicho tubo de evacuación una boca de dispuesta en una zona superior del compartimento inferior del depósito, próxima la placa superior, y una boca de salida de aire al exterior de dicho depósito. One of the features of the invention is that the filtration system comprises a tube for evacuating the pressurized air supplied for the regeneration of the filter medium, said evacuation tube comprising an inlet arranged in an upper area of the lower compartment of the tank, close to the upper plate, and an inlet for air outlet to the outside of said tank.
La salida de aire a través de este tubo de evacuación garantiza que el caudal de aire presurizado introducido en el depósito durante la regeneración del medio filtrante pueda ascender por el compartimento inferior del depósito y salir al exterior, realizando durante dicho movimiento ascendente la movilización del agua contenida en dicho compartimento inferior, removiendo toda la suciedad, incluso la costra de grasa y medio filtrante formada en la superficie inferior de la placa superior. The air outlet through this evacuation tube ensures that the pressurised air flow introduced into the tank during the regeneration of the filter medium can ascend through the lower compartment of the tank and exit to the outside, carrying out during said upward movement the mobilisation of the water contained in said lower compartment, removing all the dirt, including the crust of grease and filter medium formed on the lower surface of the upper plate.
Otra ventaja proporcionada por este tubo de evacuación, es que el aire presurizado introducido en el depósito para la regeneración del material filtrante no genera en el compartimento inferior una presión suficiente para desplazar el agua por el interior de los latiguillos hacia el compartimento superior y expulsarla innecesariamente hacia el exterior con lo que durante dicha fase de regeneración la cantidad de agua desechada es muy reducida, y la mayor parte de la misma permanece en el compartimento inferior, realizando una la limpieza efectiva de la parte superior de compartimento inferior y la eliminación de la costra acumulada por debajo de la placa superior. Another advantage provided by this evacuation tube is that the pressurised air introduced into the tank for the regeneration of the filtering material does not generate sufficient pressure in the lower compartment to displace the water through the inside of the hoses towards the upper compartment and expel it unnecessarily to the outside, meaning that during this regeneration phase the amount of water discarded is very small, and most of it remains in the lower compartment, effectively cleaning the upper part of the lower compartment and removing the crust accumulated below the upper plate.
El sistema de filtrado de líquidos objeto de esta invención presenta otras características adicionales que contribuyen a la regeneración completa del medio filtrante y que impiden que parte de la perlita o medio filtrante quede acumulado en las zonas resguardadas de las corrientes ascendentes de aire y agua. The liquid filtration system object of this invention has other additional characteristics that contribute to the complete regeneration of the filter medium and that prevent part of the perlite or filter medium from accumulating in the areas protected from the ascending currents of air and water.
Para ello, y de acuerdo con la invención la placa distribuidora de líquido comprende en su contorno una serie de rebajes que delimitan junto con la pared lateral del depósito unas ventanas de paso y caída hacia la zona inferior del medio filtrante liberado de los latiguillos durante su regeneración. For this purpose, and in accordance with the invention, the liquid distribution plate comprises a series of recesses in its outline which, together with the side wall of the tank, delimit windows for the passage and drop towards the lower area of the filter medium released from the hoses during its regeneration.
Para evitar la acumulación de la perlita o medio filtrante en la boca de hombre, dicha boca de hombre comprende un cuerpo tubular montado en una posición sensiblemente horizontal en una abertura definida en la pared lateral del depósito y que se adentra en el cuerpo del depósito; comprendiendo dicho cuerpo tubular una tapa de cierre montada sobre el extremo del cuerpo tubular alojado en el depósito y que impide que la perlita o medio filtrante pueda acceder y quedar retenida en el interior del mencionado cuerpo tubular de la boca de hombre. In order to prevent the accumulation of perlite or filter medium in the manhole, said manhole comprises a tubular body mounted in a substantially horizontal position in an opening defined in the side wall of the tank and which extends into the body of the tank; said tubular body comprising a closing cap mounted on the end of the tubular body housed in the tank and which prevents the perlite or filter medium from accessing and being retained inside said tubular body of the manhole.
Dicha boca de hombre está provista de una mirilla montada a rosca en la tapa y que permite inspeccionar visualmente el interior del depósito. This manhole is provided with a sight glass mounted on the cover by screw and which allows visual inspection of the inside of the tank.

Exposición detallada de modos de realización de la invención.Detailed exposition of embodiments of the invention.
En el ejemplo de realización mostrado en la figura 1, el sistema de filtración de líquido comprende un depósito (10) de poliéster reforzado con fibra de vidrio, que comprende en su interior una placa superior (20) provista de una pluralidad de orificios para el acoplamiento de los latiguillos (40) y que divide el interior de dicho depósito (10) en un compartimento inferior (101) provisto de una boca de entrada (103) del líquido a filtrar, y un compartimento superior (102) provisto de una boca de salida (104) del líquido filtrado. In the exemplary embodiment shown in Figure 1, the liquid filtration system comprises a fiberglass-reinforced polyester tank (10), which comprises an upper plate (20) provided with a plurality of holes for coupling the hoses (40) and which divides the interior of said tank (10) into a lower compartment (101) provided with an inlet (103) for the liquid to be filtered, and an upper compartment (102) provided with an outlet (104) for the filtered liquid.
El sistema de filtración comprende una placa distribuidora (30) de líquido, dispuesta horizontalmente en el compartimento inferior (101), entre el tubo de suministro de agua (106) de limpieza y el tubo de suministro de aire presurizado (105) de regeneración del medio filtrante, y provista de una pluralidad de orificios (301) de paso del líquido a filtrar hacia una multitud de latiguillos (40) que comprenden una superficie exterior que conforma un soporte de un medio filtrante (no representado) y una superficie interior que define un conducto de circulación el líquido filtrado en sentido ascendente. The filtration system comprises a liquid distribution plate (30), arranged horizontally in the lower compartment (101), between the water supply tube (106) for cleaning and the pressurized air supply tube (105) for regenerating the filter medium, and provided with a plurality of holes (301) for passing the liquid to be filtered towards a multitude of hoses (40) comprising an outer surface that forms a support for a filter medium (not shown) and an inner surface that defines a conduit for circulating the filtered liquid in an upward direction.
Los latiguillos (40) comprenden un extremo inferior (401) cerrado y un extremo superior abierto (402) acoplado al correspondiente orificio de la placa superior (20) y por el que pasa el líquido filtrado hacia el compartimento superior (102). The hoses (40) comprise a closed lower end (401) and an open upper end (402) coupled to the corresponding hole in the upper plate (20) and through which the filtered liquid passes towards the upper compartment (102).
El compartimento inferior (101) dispone de un tubo de suministro de agua (106) para la limpieza periódica del filtro; un tubo de suministro de aire presurizado (105) para la regeneración del medio filtrante y una boca de vaciado (110). The lower compartment (101) has a water supply tube (106) for periodic cleaning of the filter; a pressurized air supply tube (105) for regeneration of the filter medium and a drain port (110).
El depósito (10) comprende en el compartimento inferior (101) una boca de conexión (108) de una manguera para la carga de la perlita o medio filtrante, y en el compartimento superior (102) una boca de conexión (109) un aspirador que facilita dicha carga de perlita, una válvula de aireación (107) y un sensor de nivel (111). The tank (10) comprises in the lower compartment (101) a connection mouth (108) of a hose for loading the perlite or filter medium, and in the upper compartment (102) a connection mouth (109) a vacuum cleaner that facilitates said loading of perlite, an aeration valve (107) and a level sensor (111).
El funcionamiento del sistema de filtrado es controlado de forma convencional mediante un panel de control (no representado) que gestiona los ciclos de limpieza del filtro y de regeneración del medio filtrante de perlita. The operation of the filtration system is controlled in a conventional manner by a control panel (not shown) that manages the filter cleaning cycles and the regeneration of the perlite filter media.
De acuerdo con la invención, este sistema comprende un tubo de evacuación (50) de aire provisto de una boca de entrada (501) dispuesta en una zona del compartimento inferior (101) próxima a la placa superior (20), y una boca de salida (502) al exterior del depósito (10). According to the invention, this system comprises an air evacuation tube (50) provided with an inlet (501) arranged in an area of the lower compartment (101) close to the upper plate (20), and an outlet (502) to the outside of the tank (10).
Tal como se ha mencionado la función de este tubo de evacuación (50) es permitir la salida al exterior del aire introducido en el compartimento inferior (101) por el tubo de suministro de aire presurizado (105) durante la regeneración del medio filtrante. As mentioned, the function of this evacuation tube (50) is to allow the air introduced into the lower compartment (101) through the pressurized air supply tube (105) to escape to the outside during the regeneration of the filter medium.
Este tubo de evacuación (50) de aire permite que el aire introducido durante la regeneración del medio filtrante movilice el agua contra la superficie inferior de la placa superior (20) provocando la limpieza de la costra acumulada en dicha zona, y que a continuación el aire salga al exterior. This air evacuation tube (50) allows the air introduced during the regeneration of the filter medium to mobilize the water against the lower surface of the upper plate (20), causing the accumulated crust in said area to be cleaned, and then the air to escape to the outside.
Por tanto, el mencionado tubo de evacuación (50) evita que el aire presurizado introducido en el compartimento inferior durante la regeneración del medio filtrante, se acumule en la zona superior del compartimento inferior que se encuentra obstruida por la costra de grasas y perlita, y genere una sobrepresión capaz de provocar que el agua acceda al interior de los latiguillos por la zona inferior de los mismos y sea desplazada hacia al compartimento superior y salga al exterior, provocando una pérdida importante de agua y un descenso del nivel de agua en el compartimento inferior (101), lo que impide que el agua alcance a eliminar de costra acumulada debajo de la placa superior (20). Therefore, the aforementioned evacuation tube (50) prevents the pressurized air introduced into the lower compartment during the regeneration of the filter medium from accumulating in the upper area of the lower compartment which is obstructed by the crust of grease and perlite, and generating an overpressure capable of causing the water to access the interior of the hoses through the lower area thereof and be displaced towards the upper compartment and exit to the outside, causing a significant loss of water and a drop in the water level in the lower compartment (101), which prevents the water from reaching to remove the crust accumulated under the upper plate (20).
Durante la regeneración el medio filtrante de perlita se suelta de los latiguillos (40) y cae hacia la zona inferior del depósito (10). During regeneration the perlite filter medium comes loose from the hoses (40) and falls to the lower area of the tank (10).
Como se puede observar en la figura 2, para obtener una regeneración completa del medio filtrante la placa distribuidora (30) de líquido comprende en su contorno una serie de rebajes (302) que conforman junto con la pared lateral del depósito (10) unas ventanas de paso hacia la zona inferior del depósito del medio filtrante liberado de los latiguillos durante su regeneración o en la fase de limpieza. As can be seen in figure 2, to obtain a complete regeneration of the filter medium, the liquid distribution plate (30) comprises in its contour a series of recesses (302) that form, together with the side wall of the tank (10), passage windows towards the lower area of the tank of the filter medium released from the hoses during its regeneration or in the cleaning phase.
