La invención se sitúa preferentemente en el ámbito de la industria químico-alimentaria, concretamente en el ámbito de la obtención de aceite, si bien es aplicable en cualquier proceso en el que sea necesario separar el líquido de una mezcla sólido/líquido.The invention is preferably located in the scope of the chemical-food industry, specifically in the field of obtaining oil, although it is applicable in any process in which it is necessary to separate the liquid of a solid / liquid mixture.
Con independencia de otros detalles estructurales que no vienen al caso, las prensas hidráulicas conocidas hasta el momento presentan como denominador común el estar basadas en el principio de Pascal para su funcionamiento, según el cual, la presión aplicada a un líquido encerrado dentro de un recipiente se transmite por igual a todos los puntos del fluido y a las propias paredes del recipiente.Regardless of other details Structural factors that are not relevant, hydraulic presses known so far have the common denominator to be based on the Pascal principle for its operation, according to the which, the pressure applied to a liquid enclosed within a vessel is transmitted equally to all points of the fluid and to The walls of the vessel itself.
De forma más concreta y de acuerdo con tal denominador común, las prensas hidráulicas existentes en el mercado están constituidas básicamente por un pistón o émbolo desplazable longitudinalmente (en el seno de una camisa es lo más corriente) y en contra de una plataforma fija sobre la que presiona al producto a prensar. Dado que se trata de la obtención de la fase líquida participante en un producto determinado, la citada camisa o en su defecto el plato de recepción, en un lugar apropiado dispone de un orificio para evacuación del citado líquido.More specifically and in accordance with such common denominator, the existing hydraulic presses in the market they consist basically of a piston or piston movable longitudinally (within a shirt is the most common) and against a fixed platform on which it presses the product to press. Since it is about obtaining the liquid phase participant in a particular product, the said shirt or in his defect the reception plate, in an appropriate place has a hole for evacuation of said liquid.
El rendimiento de estas prensas es función exclusivamente de la presión suministrada al citado pistón, y sin embargo y como es obvio, sería deseable poder incrementar sustancialmente dicho rendimiento.The performance of these presses is a function exclusively of the pressure supplied to said piston, and without however, and obviously, it would be desirable to be able to increase substantially said performance.
La prensa hidráulica para extracción de líquidos que la invención propone, constituye un avance técnico frente a las prensas hidráulicas convencionales, al permitir incrementar su rendimiento de forma notable, sin incrementar las dimensiones del pistón ni la potencia aplicada al mismo.The hydraulic press for liquid extraction that the invention proposes, constitutes a technical advance against the conventional hydraulic presses, allowing to increase their performance significantly, without increasing the dimensions of the piston or the power applied to it.
Para ello de forma mas concreta, la prensa hidráulica que se preconiza, a partir de la estructuración básica similar a la de una prensa hidráulica convencional del tipo anteriormente citado, es decir provista de un pistón de accionamiento hidráulico que en el presente caso juega en el interior de una camisa fija, centra sus características en el hecho de que el citado pistón cuenta además con una prolongación interior, axial, que conecta para discurrir, en un cilindro o camisa complementaria, de manera que en la maniobra de accionamiento del citado pistón y además de la presión convencional generada por el mismo, se pueda producir intencionalmente una presión auxiliar, es decir una presión interna sobre el producto, que mejora el rendimiento de la prensa.To do this more specifically, the press hydraulics that is recommended, from the basic structuring similar to that of a conventional hydraulic press of the type previously mentioned, that is to say provided with a piston of hydraulic drive that in this case plays in the interior of a fixed shirt, focuses its characteristics on the fact that said piston also has an internal extension, axial, which connects to run, in a cylinder or sleeve complementary, so that in the maneuver of actuation of the cited piston and in addition to the conventional pressure generated by the same, an auxiliary pressure can be intentionally produced, it is say an internal pressure on the product, which improves the press performance.
De acuerdo con lo anterior y con lo característico de la invención, la plataforma superior o testa de la prensa, incorpora un alojamiento dimensional y formalmente adecuado para recibir ajustadamente a la prolongación axial del pistón.In accordance with the above and with characteristic of the invention, the upper platform or testa of the press, incorporates dimensional and formally adequate accommodation to receive tightly to the axial extension of the piston.
Según otra de las características del pistón, la citada prolongación axial del pistón es hueca y tiene su pared profusamente perforada, mientras que el alojamiento previsto para el mismo, en su cilindro o camisa, cuenta con una toma de líquido a presión que genere y potencie la efectividad en la citada presurización interna.According to another of the characteristics of the piston, the cited axial extension of the piston is hollow and has its wall profusely perforated, while the accommodation provided for the same, in his cylinder or shirt, has a liquid intake to pressure that generates and enhances the effectiveness in the aforementioned internal pressurization
Se ha previsto también que como medio presurizador de la prolongación axial del pistón, se utilice, en circuito cerrado, cualquier líquido adecuado.It is also planned that as a means axial piston extension pressurizer, be used in closed circuit, any suitable liquid.
De acuerdo con otra de las características de la invención se ha previsto que en el seno de la camisa del cargo, se establezcan una pluralidad de estratos filtrantes, constituidos cada uno de ellos por una sustancia vegetal de dureza y granulometría apropiadas, como por ejemplo, fragmentos de hueso vegetal, estratos filtrantes, que alternados con la masa de producto a comprimir, facilitan la salida de líquidos producidos por la compresión.According to another of the characteristics of the It has been foreseen that within the shirt of the office, establish a plurality of filter strata, constituted each one of them for a hard substance and granulometry plant substance appropriate, such as fragments of plant bone, strata Filters, which alternated with the mass of product to compress, facilitate the exit of liquids produced by compression.
Solo resta señalar por último que la prensa hidráulica es susceptible de funcionar mediante acción conjunta de las dos presiones existentes, o bien mediante la utilización independiente de una y otra o mediante cualquier secuencia o alternancia.It only remains to point out finally that the press Hydraulics is likely to work by joint action of the two existing pressures, or by using independent of one or the other or by any sequence or alternation.
Para complementar la descripción que se está realizando y con objeto de ayudar a una mejor comprensión de las características del invento, de acuerdo con un ejemplo preferente de realización práctica del mismo, se acompaña como parte integrante de dicha descripción, un juego único de dibujos en donde con carácter ilustrativo y no limitativo, se ha representado esquemáticamente en alzado y en sección, una prensa hidráulica para extracción de líquidos realizada de acuerdo con el objeto de la presente invención.To complement the description that is being performing and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical realization of it, is accompanied as an integral part of said description, a unique set of drawings where with character illustrative and not limiting, it has been schematically represented in elevation and section, a hydraulic press for extraction of liquids made in accordance with the purpose of this invention.
En las figuras reseñadas se ha representado una prensa de funcionamiento vertical, en la que participa un chasis fijo (1), convenientemente afianzado al suelo, que constituye el soporte para un cilindro hidráulico en el que participa una camisa (2), solidaria al chasis (1) mediante el soporte (3), camisa en cuyo seno juega un émbolo (4) que crea, con la camisa (2), una cámara (5) y que es desplazable mediante la presurización de dicha cámara (5) a través de una entrada (6) de fluido a presión. El émbolo (4) es solidario al vástago (7) del cilindro hidráulico, vástago que a su vez se remata por su otro extremo en un pistón (8) que juega herméticamente en una camisa (9) solidarizada al chasis (1), concretamente a una plataforma (10) o plato de recepción que cierra la cámara (11) definida por la camisa (9) y el pistón (8).In the figures outlined, a vertical operating press, in which a chassis participates fixed (1), conveniently anchored to the ground, which constitutes the support for a hydraulic cylinder in which a jacket participates (2), integral to the chassis (1) by means of the support (3), a jacket in which breast plays a plunger (4) that creates, with the shirt (2), a chamber (5) and that it is movable by pressurizing said chamber (5) to through an inlet (6) of pressurized fluid. The plunger (4) is attached to the rod (7) of the hydraulic cylinder, rod to its once it ends at its other end in a piston (8) that plays tightly in a shirt (9) in solidarity with the chassis (1), specifically to a platform (10) or reception plate that closes the chamber (11) defined by the jacket (9) and the piston (8).
De acuerdo ya con la invención, el pistón (8) cuenta con una prolongación axial (12), tubular y afectada por una gran profusión de perforaciones (13), de manera que dicha prolongación axial (12) acompaña al pistón (8) en su desplazamiento axial o movimiento que viene permitido por la existencia en la plataforma (10) que cierra la camisa (9) de un alojamiento (14) capaz de recibir a la prolongación (12) y que está a su vez provisto de una entrada (15) de líquido a presión.In accordance with the invention, the piston (8) it has an axial extension (12), tubular and affected by a large profusion of perforations (13), so that said axial extension (12) accompanies the piston (8) in its displacement axial or movement that is allowed by the existence in the platform (10) that closes the jacket (9) of a housing (14) able to receive the extension (12) and which is in turn provided of an inlet (15) of liquid under pressure.
Tal como anteriormente se ha dicho, para suministrar esta presión interna a la cámara (11), desde el tubo prolongación axial (12) del pistón (8), se ha previsto utilizar cualquier fluido adecuado a la obtención que se pretende.As previously stated, for supply this internal pressure to the chamber (11), from the tube axial extension (12) of the piston (8), it is planned to use any fluid suitable for the intended purpose.
Tal como se ha representado esquemáticamente en la figura, se ha previsto que el citado producto (16) a exprimir forme en el seno de la cámara (11) capas alternadas con estratos filtrantes (17) a base de fragmentos de hueso vegetal, como por ejemplo los de la aceituna, cuando la prensa hidráulica se está utilizando para obtener aceite de dichas aceitunas.As schematically represented in the figure, it is provided that said product (16) to be squeezed form layers alternated with strata inside the chamber Filters (17) based on fragments of plant bone, as per example those of the olive, when the hydraulic press is using to obtain oil from said olives.
Tal como ya se ha dicho con anterioridad, la prensa hidráulica puede funcionar a expensas de la aplicación simultanea de las dos presiones, la generada por el cilindro hidráulico (2-4) y la generada a través de la prolongación axial o tubo (12), o bien puede funcionar utilizando dichas presiones aisladamente o de forma alternada.As previously stated, the hydraulic press can work at the expense of the application simultaneous of the two pressures, the one generated by the cylinder hydraulic (2-4) and the one generated through the axial extension or tube (12), or it can work using said pressures in isolation or alternately.
A partir de esta estructuración, el funcionamiento del dispositivo es como sigue:From this structuring, the Device operation is as follows:
Con el pistón (8) en la posición mas baja para el mismo, se establece sobre el interior de la camisa (9) el material a exprimir, formando capas alternadas con otras en funciones de material filtrante.With the piston (8) in the lowest position to it is established on the inside of the shirt (9) the material to be squeezed, forming layers alternated with others in filter material functions.
Se provoca el desplazamiento vertical del vástago (7), mediante entrada de fluido a presión a través de la entrada (6), el producto a exprimir se presiona contra la plataforma (10), de manera que el líquido es extraído a través de una salida, no representada en las figuras, que podrá disponerse indistintamente sobre la plataforma (10) o a través de la zona superior de la camisa (9).Vertical displacement of the rod (7), by means of pressurized fluid inlet through the input (6), the product to be squeezed is pressed against the platform (10), so that the liquid is extracted through an outlet, not represented in the figures, which may be arranged interchangeably on the platform (10) or through the upper area of the shirt (9).
El ascenso del pistón (8) provoca el consecuente ascenso de la prolongación axial (12) tubular, de manera que cuando comienza a encajar en el alojamiento (14), momento en el que es precisa una mayor presión para continuar con el prensado del material de que se trate, es posible incrementar dicha presión, mediante la impulsión de fluido a presión a través de la entrada (15), presión que se transmitirá a través de dicha prolongación axial (12) y que se repartirá radialmente sobre la misma, a través de las perforaciones (13).The rise of the piston (8) causes the consequent rise of tubular axial extension (12), so that when begins to fit into the housing (14), at which time it is more pressure is required to continue pressing the material in question, it is possible to increase said pressure, by pushing fluid under pressure through the inlet (15), pressure to be transmitted through said extension axial (12) and that will be distributed radially on it, through of the perforations (13).
Así pues, una vez enchufada la prolongación axial (12) en el alojamiento (14), podrá aplicarse presión en el seno de la cámara (11) bien a través de la entrada (15), bien a través de la presión ejercida a través de la entrada (6), o bien a través de ambas.So, once the extension is plugged in axial (12) in the housing (14), pressure may be applied to the sine of the chamber (11) either through the entrance (15), or through the pressure exerted through the inlet (6), or through both.
