El objeto de la presente invención recae en un dispositivo de limpieza que, constituido esencialmente a partir de una hélice accionada por un motor independiente, cuya hélice queda situada en el interior del filtro y el motor fuera del filtro mediante un cierre mecánico para asegurar la estanqueidad, presenta como finalidad provocar, al activarse la hélice con el filtro parado y lleno de agua junto con el medio filtrante, consistente de preferencia en perlita o similar, un flujo turbulento en rotación espiral con una trayectoria cerrada, de tal manera que arrastra el medio filtrante, el cual actúa como producto para deshacer la precapa de la manga, quedando completamente limpia de perlita (o medio filtrante similar) y sin que la sostenga la materia grasa que suele contener.The object of the present invention lies in a cleaning device that, essentially constituted from a propeller driven by an independent motor, whose propeller is located inside the filter and the motor outside the filter by means of a mechanical seal to ensure tightness. , its purpose is to cause, when the propeller is activated with the filter stopped and filled with water together with the filter medium, preferably consisting of perlite or similar, a turbulent flow in spiral rotation with a closed path, in such a way that it drags the medium filter, which acts as a product to undo the precoat of the bag, leaving it completely clean of perlite (or similar filter medium) and without being held by the greasy matter it usually contains.
CAMPO DE APLICACIÓN DE LA INVENCIÓNFIELD OF APPLICATION OF THE INVENTION
El campo de aplicación de la presente invención se enmarca dentro del sector de la industria dedicada a la fabricación de sistemas de filtrado mediante colectores de candelas y mangas, para líquidos.The field of application of the present invention falls within the industry sector dedicated to the manufacture of filtering systems using candle and sleeve collectors for liquids.
ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION
Las mangas de las candelas o colectores, comprenden filtros regenerativos que utilizan, como medio filtrante, perlita, diatomeas o similar, entendiendo, al hablar de filtros regenerativos, a aquellos en que se regenera el medio filtrante para alargar su autonomía, recolocándolo para aprovechar todo el espacio disponible de dicho medio filtrante, perlita, diatomeas.... The sleeves of the candles or collectors include regenerative filters that use perlite, diatoms or similar as a filter medium, understanding, when speaking of regenerative filters, those in which the filter medium is regenerated to extend its autonomy, repositioning it to take advantage of everything. the available space of said filter medium, perlite, diatoms....
Estos filtros, para una correcta funcionalidad, requieren de una limpieza periódica de los mismos. Actualmente, se contemplan sistemas de limpieza con agua presión o aire con entrada directa desde el exterior del filtro o bien en recirculación.These filters, for correct functionality, require periodic cleaning. Currently, cleaning systems are contemplated with water pressure or air with direct entry from the outside of the filter or with recirculation.
Sin embargo, la entrada y salida de agua o aire en el interior del filtro requiere de dispositivos tales como bombas auxiliares y detectores de aire para evitar enviar aire a la instalación.However, the entry and exit of water or air inside the filter requires devices such as auxiliary pumps and air detectors to avoid sending air into the installation.
El concepto de regeneración del medio filtrante, como por ejemplo en el caso de la perlita y similares, recae en hacer desprender la precapa del medio filtrante de la manga del colector o candela para su nueva recolocación. En algunos tipos de filtrado, el líquido a filtrar contiene materia grasa que se adhiere a las mangas de las candelas ó colectores junto con el medio filtrante y no permite la caída de la precapa. Esto es debido a que la materia grasa ha creado una estructura con el medio filtrante y no se desprende fácilmente.The concept of regeneration of the filter medium, as for example in the case of perlite and the like, involves detaching the prelayer of the filter medium from the sleeve of the collector or candle for its new replacement. In some types of filtration, the liquid to be filtered contains fatty matter that adheres to the sleeves of the candles or collectors along with the filter medium and does not allow the precoat to fall. This is because the fatty matter has created a structure with the filter medium and does not come off easily.
El objetivo de la presente invención es, pues, el desarrollo de un sistema de limpieza del filtro alternativo que evite dicha problemática.The objective of the present invention is, therefore, the development of an alternative filter cleaning system that avoids said problem.
Por otra parte, y como referencia al estado actual de la técnica, cabe señalar que, al menos por parte de la solicitante, se desconoce la existencia de ningún otro dispositivo de limpieza, ni ninguna otra invención de aplicación similar, que presente unas características técnicas, iguales o semejantes a las que presenta el que aquí se reivindica.On the other hand, and as a reference to the current state of the art, it should be noted that, at least on the part of the applicant, the existence of any other cleaning device, nor any other invention of similar application, that presents technical characteristics is unknown. , equal or similar to those presented by the one claimed here.
EXPLICACIÓN DE LA INVENCIÓNEXPLANATION OF THE INVENTION
El dispositivo de limpieza de filtros para líquidos de candelas con sistema de regeneración del medio filtrante que la invención propone se configura como la solución idónea al objetivo anteriormente señalado, estando los detalles caracterizadores que lo hacen posible y que lo distinguen convenientemente recogidos en las reivindicaciones finales que acompañan a la presente descripción.The filter cleaning device for candle liquids with a filter medium regeneration system that the invention proposes is configured as the ideal solution for the aforementioned objective, with the characterizing details that make it possible and that distinguish it conveniently included in the final claims. that accompany this description.
Concretamente, lo que la invención propone, como se ha apuntado anteriormente, es un dispositivo de limpieza que, conformado esencialmente a partir de una hélice accionada por un motor independiente, donde la hélice queda en el interior del filtro y el motor fuera del filtro mediante un cierre mecánico para asegurar la estanqueidad, tiene como finalidad, al activarse la hélice con el filtro parado y lleno de agua junto con el medio filtrante, consistente de preferencia en perlita o similar, provocar un flujo turbulento en rotación espiral con una trayectoria cerrada, de tal modo que arrastra el medio filtrante, que actúa como producto para deshacer la precapa de la manga, quedando completamente limpia de perlita (o medio filtrante similar) y sin que la sostenga la materia grasa que suele contener.Specifically, what the invention proposes, as noted above, is a cleaning device that, essentially made up of a propeller driven by an independent motor, where the propeller remains inside the filter and the motor outside the filter. by means of a mechanical seal to ensure tightness, its purpose, when the propeller is activated with the filter stopped and full of water together with the filter medium, preferably consisting of perlite or similar, is to cause a turbulent flow in spiral rotation with a closed path. , in such a way that it drags the filter medium, which acts as a product to undo the precoat of the bag, leaving it completely clean of perlite (or similar filter medium) and without being held by the greasy matter that it usually contains.
Más específicamente, el dispositivo objeto de la presente invención se refiere a un sistema de limpieza para las mangas de las candelas o colectores que, esencialmente, comprende una serie de elementos destinados a efectuar un movimiento del flujo del agua dentro del filtro. En particular, el dispositivo de la invención está especialmente diseñado para los filtros regenerativos, especialmente para los que utilizan como medio filtrante perlita, diatomeas u otro elemento similar.More specifically, the device object of the present invention refers to a cleaning system for the sleeves of the candles or collectors that, essentially, comprises a series of elements intended to effect a movement of the water flow within the filter. In particular, the device of the invention is specially designed for regenerative filters, especially for those that use perlite, diatoms or other similar elements as filter media.
Como se ha señalado en el apartado de antecedentes, se conocen varios modelos de sistema de limpieza con agua presión o aire con entrada directa desde el exterior del filtro o bien en recirculación, en los cuales, la entrada y salida de agua o aire en el interior del filtro, requiere de dispositivos tales como bombas auxiliares y detectores de aire para evitar enviar aire a la instalación.As noted in the background section, several models of cleaning systems with pressurized water or air are known with direct entry from the outside of the filter or with recirculation, in which the entry and exit of water or air in the inside the filter, requires devices such as auxiliary pumps and air detectors to avoid sending air to the installation.
El concepto de regeneración del medio filtrante, como por ejemplo en el caso de la perlita y similares, radica en hacer desprender la precapa del medio filtrante de la manga del colector o candela para su nueva recolocación.The concept of regeneration of the filter medium, as for example in the case of perlite and the like, lies in detaching the prelayer of the filter medium from the sleeve of the collector or candle for its new replacement.
En algunos tipos de filtración, el líquido a filtrar contiene materia grasa que se adhiere a las mangas de las candelas ó colectores junto con el medio filtrante y no permite la caída de la precapa. Esto es debido a que la materia grasa ha creado una estructura con el medio filtrante y no se desprende fácilmente.In some types of filtration, the liquid to be filtered contains fatty matter that adheres to the sleeves of the candles or collectors along with the filter medium and does not allow the precoat to fall. This is because the fatty matter has created a structure with the filter medium and does not come off easily.
Para evitar dicho problema, el dispositivo objeto de la presente invención comprende, esencialmente, una hélice con motor independiente, cuya hélice queda dispuesta en el interior del filtro y el motor fuera del filtro, estando ambos elementos vinculados entre sí mediante un cierre mecánico para asegurar la estanqueidad. To avoid said problem, the device object of the present invention essentially comprises a propeller with an independent motor, whose propeller is arranged inside the filter and the motor outside the filter, both elements being linked together by a mechanical seal to ensure the tightness.
Con ello, al activarse la hélice, con el filtro parado y lleno de agua junto con el medio filtrante, se provoca un flujo turbulento en rotación espiral con una trayectoria cerrada.With this, when the propeller is activated, with the filter stopped and filled with water along with the filter medium, a turbulent flow is caused in spiral rotation with a closed path.
Esta vorticidad del flujo arrastra el medio filtrante que actúa como producto para deshacer la precapa de la manga, quedando dicha manga completamente limpia de perlita (o del medio filtrante similar con que cuente) y sin que la sostenga la materia grasa, por lo que el material filtrante del interior del filtro, como en el caso de la perlita u otro material de características similares, queda libre de las mangas de las candelas o colectores, regenerado y listo para un próximo ciclo de filtrado, en que se creará de nuevo la precapa filtrante.This vorticity of the flow drags the filter medium that acts as a product to undo the precoat of the bag, leaving said bag completely clean of perlite (or the similar filter medium that it has) and without being supported by the greasy matter, so the filter material inside the filter, such as perlite or other material with similar characteristics, is free from the sleeves of the candles or collectors, regenerated and ready for a next filtering cycle, in which the prelayer will be created again. filter.
Por otra parte, es importante destacar que el motor eléctrico que comprende el dispositivo de la invención, y que proporciona el movimiento a la hélice, está dimensionado en función de la capacidad del filtro y es instalado, preferentemente, en la parte inferior del filtro, bien en la propia base o bien en la parte lateral inferior, y siempre con una inclinación tal que permita el movimiento deseado del producto, es decir, del medio filtrante.On the other hand, it is important to highlight that the electric motor that comprises the device of the invention, and that provides movement to the propeller, is sized depending on the capacity of the filter and is preferably installed in the lower part of the filter, either on the base itself or on the lower side part, and always with an inclination such that it allows the desired movement of the product, that is, of the filter medium.
