DESCRIPCIONDESCRIPTION
Sistema de cierre y apertura para ventiladores axialesClosing and opening system for axial fans
La presente invencion se refiere a un sistema de cierre y apertura especialmente destinado a ventiladores industriales, que es adaptable a todo tipo de ventiladores axiales, especlficamente a todo ventiladores axiales del tipo de los que se instalan en las paredes o techos comunicados con el exterior sin necesidad de conductos.The present invention relates to a closing and opening system especially intended for industrial fans, which is adaptable to all types of axial fans, specifically all axial fans of the type that are installed in the walls or ceilings communicated with the outside without Need for ducts
En particular, el presente sistema permite cerrar de forma hermetica asl como abrir la zona exterior de entrada de aire, impidiendo o facilitando la ventilacion de las areas industriales donde se instala, por ejemplo naves dedicadas a la explotacion ganadera.In particular, the present system allows to close hermetically as well as to open the outside air inlet area, preventing or facilitating the ventilation of the industrial areas where it is installed, for example ships dedicated to livestock exploitation.
Los ventiladores axiales del tipo mencionado existentes en el mercado disponen de un sistema basado en lamas metalicas o plasticas que se abren o cierran en funcion de que el ventilador este o no en funcionamiento, esto es en funcion de la presion del aire, de forma que las lamas se cierran cuando el ventilador no esta en funcionamiento y se abren por la presion del flujo helicoidal de aire entrante cuando esta operativo.Axial fans of the type mentioned in the market have a system based on metal or plastic slats that open or close depending on whether the fan is working or not, this is a function of the air pressure, so that The slats are closed when the fan is not running and is opened by the pressure of the helical flow of incoming air when it is operational.
Este tipo de sistema conocido, sin embargo, no impide de forma efectiva la entrada de aire estando el ventilador no operativo, ya que se pueden generar corrientes de aire capaces de hacer oscilar las lamas o incluso abrir el paso por completo en determinadas condiciones ambientales, de forma que no constituyen un cierre hermetico.This type of known system, however, does not effectively prevent the entry of air while the fan is not operating, since air currents capable of oscillating the slats or even opening the passage completely under certain environmental conditions can be generated, so that they do not constitute a tight seal.
Asl, por ejemplo en las explotaciones ganaderas, invernaderos, secaderos o cualquier tipo de industria o nave donde es fundamental que no entre aire a traves de los ventiladores apagados, ya que el control ambiental interno es crltico, estos sistemas no son eficaces, permitiendo una circulacion de aire parasita e incontrolable, con el subsiguiente perjuicio a la explotacion. En el caso de las explotaciones ganaderas, las consecuencias de esta falta de hermetismo son fatales, ya que se producen variaciones de temperatura y/o de humedad que pueden perjudicar seriamente a los animales y que, para ser controladas, conllevan un gasto energetico adicional tanto de calefaccion como de ventilacion, dependiendo de las circunstancias ambientales.Thus, for example in livestock farms, greenhouses, dryers or any type of industry or ship where it is essential that no air enters through the fans turned off, since internal environmental control is critical, these systems are not effective, allowing a parasite and uncontrollable air circulation, with the subsequent damage to the exploitation. In the case of livestock farms, the consequences of this lack of hermeticism are fatal, since there are variations in temperature and / or humidity that can seriously harm the animals and that, to be controlled, entail additional energy expenditure both of heating and ventilation, depending on the environmental circumstances.
Una solucion a este problema serla tapar los ventiladores manualmente, mas o menos hermeticamente, y de forma fija, con cualquier lamina de material que impida el paso de aire, pero esta solucion, esencialmente de bloquear tal paso de aire, implica que tampoco este pueda salir, lo que provoca una falta de ventilacion que puede conducir a la muerte de los animales por asfixia en pocas horas.One solution to this problem would be to cover the fans manually, more or less tightly, and in a fixed way, with any sheet of material that prevents the passage of air, but this solution, essentially blocking such air passage, implies that it cannot leave, which causes a lack of ventilation that can lead to the death of animals by suffocation in a few hours.

Por ejemplo del documento EP02380088.1 se conoce un dispositivo de accionamiento centrlfugo para apertura automatica de lamas de ventiladores que se dispone en el eje ventilador, de manera que gira junto con la impulsion del motor, este giro provoca una fuerza sobre masas inerciales situadas sobre las lamas del ventilador que provocan que este se abra.For example, from document EP02380088.1 a centrifugal drive device for automatic opening of fan slats that is arranged in the fan shaft is known, so that it rotates together with the motor drive, this rotation causes a force on inertial masses located on the fan slats that cause it to open.
En el documento ES 2008158 se describe la apertura de las lamas de un extractor de aire en base al cambio de volumen de una sustancia termo-sensible que se caliente mediante resistencias electricas.Document ES 2008158 describes the opening of the slats of an air extractor based on the change in volume of a thermo-sensitive substance that is heated by electric resistors.
Estos sistemas conocidos implican incluir en el interior del ventilador dispositivos de movimiento para las lamas protectoras, por tanto deben incluirse durante el proceso de fabrication del ventilador, lo cual, ademas de elevar el alto coste, implica disenar nuevos elementos y espacios en el ventilador, en definitiva, ninguna capacidad de ser adaptados a ventiladores ya en uso.These known systems involve including movement devices for the protective slats inside the fan, therefore they must be included during the fan manufacturing process, which, in addition to raising the high cost, involves designing new elements and spaces in the fan, In short, no ability to be adapted to fans already in use.
El sistema de cierre de la presente invention permite solucionar las desventajas de los sistemas conocidos anteriormente expuestas, facilitando un sistema se adapta facilmente a cualquier ventilador axial comercial sin necesidad de manipular en su interior ni de sofisticados elementos adicionales de cierre.The closing system of the present invention allows to solve the disadvantages of the previously known known systems, facilitating a system easily adapts to any commercial axial fan without the need to manipulate in its interior nor of sophisticated additional closing elements.
Asl, el objeto de la invencion es proporcionar un sistema de cierre y apertura del flujo de aire destinado a un ventilador axial que, disponiendose por su parte exterior, esto es en la direction del medio exterior del mismo, permita cerrar el paso de aire a su traves de forma hermetica, asl como abrirlo, sin manipular el propio ventilador, independientemente de que disponga este de lamas de cierre o no.Thus, the object of the invention is to provide a system for closing and opening the air flow intended for an axial fan which, being disposed on its outer part, that is in the direction of the external means thereof, allows the air passage to be closed to its through hermetically, as well as opening it, without manipulating the fan itself, regardless of whether it has closing slats or not.
En el contexto de la presente invencion, se entiende como “ventilador axial industrial” aquel que provoca un flujo de aire en la direccion de su eje y que esta especialmente destinado a su instalacion en naves industriales, del tipo de los que se instalan en orificios practicados en paredes o techos y que ponen en comunicacion un ambiente interior con el ambiente exterior circundante.In the context of the present invention, "industrial axial fan" is understood as the one that causes an air flow in the direction of its axis and which is especially intended for installation in industrial buildings, of the type installed in holes. practiced on walls or ceilings and that communicate an interior environment with the surrounding exterior environment.
El sistema de cierre de la invencion se disena en base a un primer marco destinado a fijarse a la parte exterior o de expulsion de aire del ventilador. Unido de manera abisagrada a este primer marco, se dispone un conjunto segundo marco-contramarco que soporta entre ambos una lamina continua hecha de un material adecuado para bloquear la entrada de aire. El primer marco y el segundo marco estan igualmente unidos por sus laterales por sendos amortiguadores, fijados correspondientemente por unThe closure system of the invention is designed on the basis of a first frame intended to be fixed to the outside or for the expulsion of air from the fan. Attached in a hinged manner to this first frame, a second frame-counterframe assembly is provided that supports between them a continuous sheet made of a suitable material to block the air inlet.

Tal como se muestra en la realizacion de las fig. 1-2, el sistema de cierre esta constituido por un primer marco (1) destinado a fijarse a la parte exterior o de expulsion de aire del ventilador. En esta realizacion, el primer marco (1) se disena en base a un perfil plano que define un rectangulo abierto por uno de sus lados mayores y que se fija en correspondencia a dicha parte exterior o de expulsion de aire del ventilador. Unido de manera abisagrada a este primer marco (1), se dispone un conjunto segundo marco (2)- contramarco (22) que soporta entre ambos una lamina continua (3) hecha de un material adecuado para bloquear el flujo de aire.As shown in the embodiment of fig. 1-2, the closing system is constituted by a first frame (1) intended to be fixed to the outside or for the expulsion of air from the fan. In this embodiment, the first frame (1) is designed based on a flat profile that defines a rectangle open on one of its major sides and that is fixed in correspondence to said outer or air ejection part of the fan. Attached in a hinged manner to this first frame (1), a second frame assembly (2) is provided - counterframe (22) that supports between them a continuous sheet (3) made of a suitable material to block the air flow.
El primer marco (1) y el segundo marco (2) estan igualmente unidos por sus laterales por sendos amortiguadores (5), fijados correspondientemente por un extremo al primer marco (1) y por el otro al segundo marco (2), para evitar posibles movimientos de oscilacion no deseados cuando el ventilador esta operativo, por ejemplo debidos al propio aire expulsado por el ventilador. Con el fin de proporcionar un cierre hermetico, el perlmetro del segundo marco (2) se recubre con una junta de estanqueidad (6), preferentemente de camara de aire.The first frame (1) and the second frame (2) are also joined by their sides by two dampers (5), correspondingly fixed by one end to the first frame (1) and the other to the second frame (2), to avoid possible unwanted oscillation movements when the fan is operational, for example due to the air itself expelled by the fan. In order to provide a tight seal, the perimeter of the second frame (2) is coated with a seal (6), preferably an air chamber.
En la realizacion mostrada en la fig. 3, el primer marco (1) a fijar en el ventilador y el segundo marco (2) se corresponden en forma y tamano. Como se muestra en esta figura, opcionalmente el primer marco (1) tambien puede incluir un contramarco (12) que permita disponer entre ambos una segunda lamina continua (31) para bloquear el aire, en esteIn the embodiment shown in fig. 3, the first frame (1) to be fixed on the fan and the second frame (2) correspond in shape and size. As shown in this figure, optionally the first frame (1) can also include a counter frame (12) that allows a second continuous sheet (31) to be arranged between the two to block the air, in this
caso incluyendo dicha lamina una abertura adaptada al caudal de aire expulsado y/o a la forma del ventilador, circular como se muestra en la figura, o cuadrada, conica, etc.If said sheet includes an opening adapted to the flow of expelled air and / or the shape of the fan, circulate as shown in the figure, or square, conical, etc.
Opcionalmente, en ambas realizaciones y con el fin de asegurar el sistema de cierre cuando el ventilador esta operativo, uniendo el primer marco (1) y el segundo marco (2) 5 se disponen tensores que impiden la apertura excesiva del sistema.Optionally, in both embodiments and in order to secure the closing system when the fan is operational, joining the first frame (1) and the second frame (2) 5, tensioners are provided that prevent excessive opening of the system.
Tambien de forma opcional, los huecos laterales entre el sistema de cierre y el propio ventilador derivados de la apertura del sistema pueden protegerse o de otro modo cerrarse con un material ductil y resistente, por ejemplo triangulos de loneta sujetos tanto a la carcasa del ventilador como al sistema de cierre y que permanecen plegados cuando 10 el sistema no esta operativo, de forma que el aire se proyecte al exterior y hacia adelante sin turbulencias laterales, y/o con el fin de que la luz solar no entre directamente al interior de la nave y/o, cuando llueva, no entre agua al interior del ventilador o de la nave.Also optionally, the lateral gaps between the closing system and the fan itself derived from the opening of the system can be protected or otherwise closed with a ductile and resistant material, for example canvas triangles attached to both the fan housing and to the closing system and remain folded when the system is not operational, so that the air is projected outside and forward without lateral turbulence, and / or so that sunlight does not enter directly into the interior of the ship and / or, when it rains, do not enter water inside the fan or the ship.
Aunque en estas realizaciones la citada union abisagrada se realiza mediante tres bisagras de librillo (4), tal union no esta limitada a estas bisagras ni en cuanto al tipo ni en 15 cuanto a su numero, pudiendo utilizarse cualquier tipo de bisagra y en cualquier numero dependiendo, por ejemplo, del tamano del ventilador o de su potencia.Although in these embodiments the said hinged union is made by means of three booklet hinges (4), such union is not limited to these hinges neither in terms of type nor in terms of number, any type of hinge can be used and in any number depending, for example, on the size of the fan or its power.
El sistema de cierre de la invencion no esta limitado en cuanto a los materiales a emplear para su fabrication, pudiendo utilizarse materiales ligeros y resistentes, para los marcos y laminas, por ejemplo aluminios, acero inoxidable, policarbonato y similares. Igualmente, 20 el presente sistema variara en dimensiones y forma de acuerdo con las caracterlsticas del ventilador donde se instala,The closure system of the invention is not limited in terms of the materials to be used for its manufacture, light and resistant materials can be used for frames and sheets, for example aluminum, stainless steel, polycarbonate and the like. Similarly, the present system will vary in dimensions and shape according to the characteristics of the fan where it is installed,
El experto en la materia entendera que las realizaciones aqul mostradas son solo ilustrativas de forma que son posibles variaciones del sistema aqul descrito. Por ejemplo, en las realizaciones mostradas cuando el ventilador esta en funcionamiento el flujo de 25 aire expulsado al exterior provoca la apertura inmediata del sistema de cierre debido a la fuerza de empuje generada sobre la lamina continua. Esta apertura del sistema se puede facilitar y/o apoyar mediante un motor electrico o mediante un sistema neumatico motorizado, por ejemplo.The person skilled in the art will understand that the embodiments shown here are only illustrative so that variations of the system described herein are possible. For example, in the embodiments shown when the fan is in operation, the flow of air expelled to the outside causes the opening of the closing system immediately due to the thrust force generated on the continuous sheet. This opening of the system can be facilitated and / or supported by an electric motor or by a motorized pneumatic system, for example.
