OBJETO DE LA INVENCIÓNOBJECT OF THE INVENTION
La invención, tal como expresa el enunciado de Ia presente memoria descriptiva, se refiere a un aparato enfriador de vasos u otros recipientes, perfeccionado, y conjunto de acoplamiento para Ia extracción de CO2 líquido.The invention, as expressed in the statement of the present specification, relates to an improved apparatus for cooling vessels or other containers, and coupling assembly for the extraction of liquid CO 2 .
En particular, el objeto de Ia invención se centra en un aparato enfriador, cuya finalidad consiste en aportar a los vasos u otros recipientes una muy baja temperatura en un lapso de tiempo muy corto, mediante el rociado del mismo con CO2 líquido (criogénico), estando particularmente destinado para ser utilizado en el campo de Ia hostelería y restauración, el cual presenta una serie de perfeccionamientos, respecto a otros aparatos ya conocidos en el mercado, suponiendo una mejorada alternativa a éstos con destacables ventajas.In particular, the object of the invention is directed to a cooler apparatus, which is intended to contribute to the vessels or other containers a very low temperature in a very short period of time, by spraying thereof with liquid CO 2 (cryogenic) , being particularly intended to be used in the field of hospitality and catering, which presents a series of improvements, compared to other devices already known in the market, assuming an improved alternative to these with outstanding advantages.
Así, entre otras peculiaridades, que se describirán en detalle más adelante, el aparato propuesto presenta, como perfeccionamiento principal, Ia particularidad de contar con un diseño estructural que permite disponer el vaso o recipiente debajo de Ia boquilla pulverizadora, recibiendo Ia pulverización de gas por su parte superior, Io cual, tal como se explicará, conlleva una serie de ventajas que mejoran significativamente su funcionalidad y eficacia.Thus, among other peculiarities, which will be described in detail below, the proposed apparatus has, as the main improvement, the peculiarity of having a structural design that allows the vessel or container to be placed under the spray nozzle, receiving the gas spray by Its upper part, which, as will be explained, entails a series of advantages that significantly improve its functionality and efficiency.
Paralelamente, el aparato cuenta con un innovador conjunto de acoplamiento para Ia extracción de CO2 líquido para rociar los vasos, cuyas particularidades se describirán más adelante. CAMPO DE APLICACIÓN DE LA INVENCIÓNIn parallel, the apparatus has an innovative coupling assembly for the extraction of liquid CO 2 to spray the vessels, whose particularities will be described later. FIELD OF APPLICATION OF THE INVENTION
El campo de aplicación de Ia presente invención se enmarca dentro del sector técnico de Ia industria dedicada a Ia fabricación de aparatos y dispositivos enfriadores o refrigeradores así como a Ia industria dedicada a Ia fabricación de piezas para elementos y dispositivos de acoplamiento para extracción de gases y/o líquidos.The field of application of the present invention is part of the technical sector of the industry dedicated to the manufacture of cooling or cooling devices and devices as well as the industry dedicated to the manufacture of parts for coupling elements and devices for gas extraction and / or liquids.
ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION
Son conocidos en el mercado algunos enfriadores para vasos del tipo que aquí concierne, los cuales, generalmente, presentan características y singularidades destacadamente distintas a las del que aquí se preconiza, debiendo destacarse que, el propio solicitante, es ya titular de una solicitud de patente relativa a un aparato enfriador de vasos el cual, si bien, cumple satisfactoriamente con los objetivos para los que está especialmente diseñado, presenta determinados aspectos susceptibles de ser mejorados, siendo el objeto de Ia presente invención aportar al estado de Ia técnica un nuevo aparato para enfriar vasos u otros recipientes cuyos perfeccionamientos están encaminados a dicho objetivo.Some coolers for vessels of the type concerned here are known in the market, which generally have characteristics and singularities that are markedly different from those recommended here, it should be noted that the applicant himself is already the holder of a patent application relative to a vessel cooling apparatus which, although, satisfactorily fulfills the objectives for which it is specially designed, presents certain aspects that can be improved, being the object of the present invention to provide the state of the art with a new apparatus for cooling vessels or other containers whose refinements are aimed at said objective.
En concreto, dicho aparato, de manera sucinta, consiste en un carcasa que, interiormente, incorpora un racor de conexión que une una electroválvula al latiguillo por donde entrará el gas procedente de una botella, Ia cual está vinculada a una placa electrónica, programable digital o analógicamente, y acoplada a un regulador de caudal, formado por una pieza de latón mecanizada que calibra el flujo exacto de gas, que, a su vez, se acopla a una pieza de prolongación con una camisa interior que conecta con una segunda pieza de prolongación, sobre cuyo extremo se sitúa Ia boquilla pulverizadora difusora de frío a través de cuyos orificios emerge el gas que se aplica en el interior de los vasos a enfriar, debiendo colocarse dichos vasos sobre ella, dispuestos sobre unos portavasos previstos para tal fin en Ia carcasa. Así, uno de los principales inconvenientes que presenta dicho aparato, viene dado por el hecho de cómo es el vaso el que se sitúa sobre Ia boquilla y el gas sale hacia arriba, se corre el riesgo de provocar daños o lesiones, ya que el CO2 líquido es tan frío puede llegar a quemar si entra en contacto directo con las manos o el rostro del usuario.Specifically, said apparatus, succinctly, consists of a housing that, internally, incorporates a connection fitting that connects an electrovalve to the hose where the gas coming from a bottle will enter, which is linked to an electronic, programmable digital plate or analogically, and coupled to a flow regulator, formed by a piece of machined brass that calibrates the exact flow of gas, which, in turn, is coupled to an extension piece with an inner jacket that connects with a second piece of extension, on which end the spray diffuser nozzle of cold is placed through whose holes the gas that is applied inside the vessels to be cooled emerges, said glasses must be placed on it, arranged on cup holders provided for that purpose in the Case. Thus, one of the main disadvantages of said apparatus, is due to the fact that it is the vessel that is placed on the nozzle and the gas rises upwards, there is a risk of causing damage or injury, since CO 2 liquid is so cold it can burn if it comes into direct contact with the user's hands or face.
Por otra parte, debido a Ia presión de salida del gas, ésta puede provocar desplazamientos indeseados del vaso.On the other hand, due to the gas outlet pressure, this can cause undesired displacements of the vessel.
Asimismo, otra de las limitaciones que presentan este tipo de aparatos, es que el vaso únicamente se enfría por su parte interna, por Io que el aporte de frigorías necesario para que alcance su temperatura adecuada, es mayor que si pudiera enfriarse al mismo tiempo por dentro y por fuera, tal como sería deseable para conseguir un ahorro de consumo de gas.Likewise, another of the limitations presented by this type of apparatus is that the vessel only cools on its internal part, so that the contribution of refrigerators necessary to reach its adequate temperature is greater than if it could be cooled at the same time by inside and out, as it would be desirable to achieve savings in gas consumption.
Finalmente, el hecho de que el vaso se disponga boca abajo sobre Ia boquilla pulverizadora, impide enfriar elementos contenidos en él, tal como cubitos de hielo, cuyo enfriamiento con CO2, como es sabido, permite conservarlos durante más tiempo sin que se derritan. Circunstancia especialmente apreciable en los sectores de hostelería y restauración a los que está eminentemente enfocado el aparato.Finally, the fact that the glass is placed face down on the spray nozzle, prevents cooling elements contained in it, such as ice cubes, whose cooling with CO2, as is known, allows them to be stored for a longer time without melting. Circumstance especially noticeable in the hospitality and catering sectors to which the device is eminently focused.
Por otra parte, los conjuntos de acoplamiento para extracción de CO2 líquido, que se conocen en el mercado, si bien suelen cumplir adecuadamente con Ia misión a que están destinados, presentan ciertos aspectos susceptibles de ser mejorados, especialmente los relativos a Ia seguridad y estanqueidad del sistema.On the other hand, the coupling assemblies for the extraction of liquid CO 2 , which are known in the market, although they tend to adequately fulfill the mission to which they are intended, present certain aspects that can be improved, especially those related to safety and system tightness.
Se constata, pues, que son numerosos los aspectos a mejorar, tanto en el propio aparato como en el sistema de acoplamiento para Ia extracción del gas, centrándose el objetivo de Ia presente invención en un nuevo aparato enfriador dotado de los pertinentes perfeccionamientos para solventar de forma práctica y efectiva todos y cada uno de los inconvenientes anteriormente señalados, y sobre los cuales, se desconoce Ia existencia de ninguna otra invención que presente unas características técnicas, estructurales o de configuración semejantes.Therefore, it can be seen that there are numerous aspects to improve, both in the device itself and in the coupling system for the extraction of gas, focusing the objective of the present invention on a new cooling device equipped with the relevant improvements to solve practical and effective way each and every one of the aforementioned drawbacks, and on which, the existence of any other invention that is unknown is unknown. present similar technical, structural or configuration characteristics.

De forma concreta, el aparato en cuestión, tal como el descrito en Ia patente citada en el anterior apartado de antecedentes, y que como se ha señalado está basado en Ia utilización de CO2 líquido pulverizado desde una boquilla en un vaso o en otro recipiente para conseguir enfriarlo de forma rápida a muy baja temperatura (entre -2O0C y -3O0C), cuenta, esencialmente, como elementos funcionales, con un racor de conexión, que une una electro válvula a un latiguillo, por donde entrará el gas procedente de una bombona externa de C02, y convenientemente dotado, dicho latiguillo para su conexión a Ia bombona, de válvula de presión regulada, válvula de purga e indicador de presión. Por su parte, dicha electroválvula se halla vinculada a un microchip programable que permite regular los impulsos y pausas de salida del gas, a Ia vez que acoplada a un regulador de caudal, con al menos una pieza de prolongación, en Ia que, a su vez, se sitúa Ia boquilla pulverizadora difusora provista de orificios a través de los cuales sale el gas para enfriar el vaso o recipiente de que se trate.Specifically, the apparatus in question, such as that described in the patent cited in the previous background section, and which, as indicated above, is based on the use of liquid CO 2 sprayed from a nozzle in a glass or in another container to get it to cool quickly at a very low temperature (between -2O 0 C and -3O 0 C), it has, essentially, as functional elements, with a connection fitting, which connects an electro valve to a hose, where the gas from an external cylinder of C02, and conveniently provided, said hose for connection to the cylinder, of regulated pressure valve, purge valve and pressure gauge. On the other hand, said solenoid valve is linked to a programmable microchip that allows to regulate the impulses and pauses of gas output, while coupled to a flow regulator, with at least one extension piece, in which, at its once again, the diffuser spray nozzle is provided with holes through which the gas leaves to cool the vessel or container in question.
A partir de dicha configuración, y ya de forma caracterizadora, el aparato ahora propuesto presenta Ia particularidad de contar con un diseño estructural mediante el cual, en lugar de disponerse el vaso sobre Ia boquilla pulverizadora, dicho vaso o recipiente se dispone bajo ella, recibiendo Ia pulverización de gas por su parte superior.From said configuration, and in a characterizing way, the apparatus now proposed has the particularity of having a structural design by means of which, instead of placing the vessel on the spray nozzle, said vessel or container is arranged under it, receiving the gas spray from its top.
Para ello, el aparato se configura a partir de una base de soporte inferior, esencialmente plana, sobre Ia que se acopla, preferentemente en uno de sus lados, un cuerpo tubular hueco que se prolonga en un tramo vertical y, a cierta altura, se curva 180° incorporando en su extremo distal una campana que queda dispuesta boca abajo, elevada a cierta distancia sobre Ia antedicha base, siendo dicha distancia Ia necesaria para que entre dicha campana y Ia base se pueda colocar un vaso u otro recipiente de dimensiones más o menos convencionales y quedar ajustado bajo ella para proceder a su enfriamiento.For this, the apparatus is configured from a bottom support base, essentially flat, on which is coupled, preferably on one of its sides, a hollow tubular body that extends in a vertical section and, at a certain height, is 180 ° curve incorporating at its distal end a bell that is arranged upside down, elevated at a certain distance on the above-mentioned base, said distance being the necessary one so that between said bell and the base a vessel or other vessel of dimensions more or more can be placed less conventional and fit under it to proceed to its cooling.
En este punto, cabe mencionar que, opcionalmente, se contempla Ia incorporación de algún mecanismo que permita regular Ia citada distancia entre Ia campana y Ia base para conseguir el citado ajuste del recipiente bajo Ia campana, ya sea mediante el desplazamiento vertical del cuerpo tubular, y consecuentemente de Ia campana, por ejemplo de tipo telescópico, o bien, mediante el desplazamiento vertical de Ia zona de Ia base en Ia que se posiciona el recipiente a enfriar, por ejemplo mediante una plataforma elevable.At this point, it should be mentioned that, optionally, the incorporation of some mechanism that allows to regulate the aforementioned distance between the bell and the base to achieve said adjustment of the container under the bell is contemplated, either by vertical displacement of the tubular body, and consequently of the bell, for example of telescopic type, or, by vertical displacement of the area of the base in which the container to be cooled is positioned, for example by means of a lifting platform.
Siguiendo con Ia invención, alojados en el interior de Ia descrita campana, que actúa de carcasa protectora, se incorporan los elementos funcionales del aparato, de manera que el racor de conexión, que une Ia electroválvula al latiguillo por donde entrará el gas, se acopla en el extremo distal del cuerpo tubular y una prolongación del latiguillo discurre a través de dicho cuerpo tubular para salir por debajo de Ia base y alargase hasta Ia bombona, mientras Ia electroválvula, el microcontrolador, el regulador, el prolongador y Ia boquilla pulverizadora , respectivamente conectados entre sí, quedan orientados hacia abajo y alojados bajo Ia campana.Following the invention, housed inside the described hood, which acts as a protective housing, the functional elements of the apparatus are incorporated, so that the connection fitting, which joins the solenoid valve to the hose through which the gas will enter, is coupled at the distal end of the tubular body and an extension of the hose runs through said tubular body to exit below the base and extend to the cylinder, while the solenoid valve, the microcontroller, the regulator, the extension and the spray nozzle, respectively connected to each other, they are oriented downwards and housed under the hood.
Además, se contempla Ia incorporación de una segunda campana, algo menor que, abarcando solo el regulador, el prolongador yIn addition, the incorporation of a second bell is contemplated, somewhat smaller than, covering only the regulator, the extension and
Ia boquilla forma una envolvente más cerrada para ajustarse al borde superior del vaso o recipiente a enfriar, favoreciendo Ia circulación del gas al rebotar sobre el interior del recipiente. Esta segunda campana, al mismo tiempo, protege Ia electroválvula y el microcontrolador de su contacto directo con el gas.The nozzle forms a more closed envelope to fit the edge upper of the glass or container to cool, favoring the circulation of the gas when bouncing on the inside of the container. This second bell, at the same time, protects the solenoid valve and the microcontroller from its direct contact with the gas.
Por otra parte, y centrándonos ahora en los elementos funcionales del aparato, cabe destacar que el conjunto del regulador, prolongador y boquilla presentan también una serie de perfeccionamientos que consisten, en primer lugar, en Ia incorporación en su interior de un tubo de aislamiento, concretamente de tipo teflonado, para que el frío tenga Ia mínima pérdida de frigorías, para Io que abarca interiormente el regulador y el prolongador, hasta llegar a Ia altura de Ia boquilla pulverizadora o difusor de salida.On the other hand, and now focusing on the functional elements of the device, it should be noted that the regulator, extension and nozzle assembly also have a series of improvements that consist, first of all, of incorporating an insulating tube inside, specifically of teflonado type, so that the cold has the minimum loss of fridges, for which it covers the regulator and the extension inside, until reaching the height of the spray nozzle or diffuser outlet.
Por su parte, Ia salida del prolongador justo tras dicho tubo de teflón, presenta un estrechamiento que reduce a Ia mitad el diámetro interior del caudal de salida del citado tubo de teflón con el fin de que el gas adquiera mayor grado de presión y, habiéndose previsto, tras dicho estrechamiento un ensanchamiento cónico que Io disipa en un abanico de unos 38°, para que se expansione el gas rápidamente entrando en Ia cámara de salida de Ia boquilla de pulverización que, más o menos tiene dicho diámetro interno.On the other hand, the exit of the extension just after said Teflon tube, has a narrowing that reduces the internal diameter of the outlet flow of said Teflon tube in half so that the gas acquires a greater degree of pressure and, having provided, after said narrowing, a conical widening that dissipates it in a range of about 38 °, so that the gas expands rapidly entering the outlet chamber of the spray nozzle which, more or less has said internal diameter.
En cuanto a Ia boquilla de pulverización, en los orificios escalométricos con que cuenta para Ia pulverización del gas, y que están repartidos en tres niveles de seis orificios, además del orificio central, se han creado una serie de obstáculos en grados, mediante Ia creación en su pared interior de relieves inclinados, para que el gas, en lugar de salir directamente hacia el orificio central, encuentre dichos obstáculos y facilite Ia salida del flujo regularmente repartida por todos sus orificios de salida.As for the spray nozzle, in the stepometric orifices that it has for the spraying of the gas, and which are distributed in three levels of six holes, in addition to the central hole, a series of obstacles have been created in degrees, by means of the creation in its interior wall of inclined reliefs, so that the gas, instead of going directly towards the central hole, finds said obstacles and facilitates the flow exit regularly distributed through all its exit holes.
Con ello se consigue que, a medida que el gas busca todas las salidas, vaya perdiendo potencia de salida, con Io cual, baja Ia presión, no salpica con tanta fuerza en el vaso y se aprovecha mas el frío.With this it is achieved that, as the gas searches for all the outlets, it loses power output, with which, the pressure drops, it does not splash so hard on the vessel and the cold is used more.
Además, como tiene menor fuerza, el gas no desplaza el vaso ni Io tira y, al haber menor presión se acumula mayor cantidad de gas en el interior del vaso y, por tanto, el frío es mayor.In addition, as it has less force, the gas does not displace the vessel or pull it and, having less pressure accumulates more gas inside the vessel and, therefore, the cold is greater.
Al mismo tiempo, al entrar el gas en Ia campana interior, que es Ia que cubre Ia boquilla de salida y trabajar en vertical, se consigue, ventajosamente, que el gas salga aerodinámicamente sobre las paredes del vaso circulando hacia el extremo contrario y baje por las paredes exteriores del mismo, tanto en un lado como en el otro.At the same time, when the gas enters the inner hood, which is the one that covers the outlet nozzle and works vertically, it is advantageously achieved that the gas exits aerodynamically on the walls of the vessel circulating towards the opposite end and down the outer walls of it, both on one side and on the other.
Esto hace que Ia masa de frío, o el aporte de frigorías en el vaso no sea solo interior, sino interior y exterior, con Io cual se produce un ahorro considerable de líquido y de frío y, consecuentemente, de consumo dado que el vaso adquiere su temperatura llegando a 20 o 30 bajo cero con menor cantidad de gas, optimizándose el consumo entre un 20 y un 30%.This causes that the cold mass, or the contribution of fridges in the glass is not only internal, but internal and external, with which a considerable saving of liquid and cold is produced and, consequently, of consumption since the glass acquires its temperature reaching 20 or 30 below zero with less gas, optimizing the consumption between 20 and 30%.
También, es importante destacar que, como se ha dicho, gracias a que es Ia boquilla Ia que se coloca sobre el vaso y, por tanto, este permanece de pie, se hace posible enfriar otros elementos, además de vasos o recipientes, tales como por ejemplo cubitos de hielo. Pues bien, con Ia descrita configuración de Ia boquilla, y mediante Ia introducción en su parte interior de un sinterizado o filtro se consigue repartir todavía más homogéneamente el gas para que salga más pulverizado y más helado, llegando a salir en fase líquida nieve.Also, it is important to note that, as mentioned, thanks to the fact that it is the nozzle Ia that is placed on the glass and, therefore, this remains standing, it becomes possible to cool other elements, in addition to vessels or containers, such as for example ice cubes. Well, with the described configuration of the nozzle, and by means of the introduction in its interior of a sinter or filter it is possible to distribute the gas even more homogeneously so that it leaves more pulverized and more frozen, reaching snow in liquid phase.
Esta nieve, tiene Ia ventaja de que absorbe el agua de los cubitos de hielo creando una especie de nieve artificial que los cubre, y que al absorber dicha humedad del hielo, su disipación, como tiene que ser de forma natural, por evaporación de ella misma, no deja residuos generando un humo blanco que produce un efecto llamativo, especialmente valorado.This snow has the advantage that it absorbs the water from the ice cubes creating a kind of artificial snow that covers them, and that by absorbing said moisture from the ice, its dissipation, as it has to be naturally, by evaporation of it It does not leave residues generating a white smoke that produces a striking effect, especially valued.
Por otra parte, en Io relativo al conjunto de acoplamiento para extracción del CO2 líquido con que cuenta el aparato es del tipo que comprende un latiguillo, que tendrá más o menos longitud, según convenga en cada caso, y en cuyos extremos incorpora sendas tuercas giratorias para su conexionado al grupo de acoplamiento a Ia botella y al racor de conexión del aparato enfriador, debiendo señalarse que este conjunto es apto, además de para el aparato preconizado, para cualquier otro aparato enfriador.On the other hand, in relation to the coupling assembly for the extraction of liquid CO 2 that the device has, it is of the type that comprises a hose, which will have more or less length, as appropriate in each case, and at whose ends it incorporates two nuts swivels for connection to the coupling group to the bottle and to the connection fitting of the cooling device, it should be noted that this assembly is suitable, in addition to the recommended device, for any other cooling device.
Es importante mencionar que el citado latiguillo destinado para Ia conducción del gas criogénico desde Ia botella al enfriador, se configura como un conducto flexible constituido por una malla reforzada de acero inoxidable que recubre un tubo interior liso, realizado preferentemente de PTFE (politetrafluoretileno), de espesor fino resistente al fuego, químicamente inerte y apto para uso alimentario, el cual cuenta, exteriormente, con un cable de seguridad, que se fija, al menos en sus dos extremos, mediante unas arandelas para mantenerlo unido a él, y forma sendos bucles, uno en cada extremo del conducto, con correspondientes tensores, que sirven para su fijación al enfriador y a Ia botella en orden a evitar un eventual distanciamiento excesivo entre dichos elementos, que pudiera dañar o poder en riesgo Ia conexión.It is important to mention that the said hose destined for the conduction of the cryogenic gas from the bottle to the cooler, is configured as a flexible conduit constituted by a reinforced stainless steel mesh that covers a smooth inner tube, preferably made of PTFE (polytetrafluoroethylene), of Thin thickness resistant to fire, chemically inert and suitable for food use, which has, externally, with a safety cable, which is fixed, at least at its two ends, by means of washers to keep it attached to it, and forms two loops , one at each end of the duct, with corresponding tensioners, which serve to fix it to the cooler and to the bottle in order to avoid eventual excessive distancing between said elements, which could damage or power the connection at risk.
Por su parte, el grupo de acoplamiento a Ia botella está formado, esencialmente, por un cuerpo de conexión central, con base de latón, que ha sido mecanizado con diferentes orificios para el acoplamiento y alojamiento de los demás elementos de conexión y de seguridad que forman dicho grupo.For its part, the coupling group to the bottle is essentially formed by a central connection body, with a brass base, which has been machined with different holes for the coupling and housing of the other connection and safety elements that They form that group.
Así, por Ia parte inferior del citado cuerpo de conexión, se acoplan un disco de ruptura y un tapón de sujeción de dicho disco, para evacuación de gas y evacuar Ia posible rotura del mismo.Thus, through the lower part of said connection body, a rupture disk and a holding plug of said disk are coupled, for gas evacuation and to evacuate the possible rupture thereof.
En uno de los laterales del cuerpo de conexión, el destinado para su conexión a Ia botella y que es ligeramente más amplio que el resto, se acoplan un disco sinterizado a modo de filtro, que queda dispuesto justo en Ia entrada central del líquido de Ia botella, y que sirve para filtrar cualquier micropartícula que pudiera dañar las electroválvulas y el circuito del enfriador, existiendo tras dicho disco de filtro, una tuerca de conexión a Ia botella, un espárrago de conexión dotado interiormente de un tubo de aislamiento, que preferentemente será teflonado, y una junta tórica para unir el cuerpo central y el espárrago de unión a Ia botella.On one of the sides of the connection body, the one intended for connection to the bottle and which is slightly wider than the rest, a sintered disk is coupled as a filter, which is arranged just at the central inlet of the liquid of the Ia bottle, and which serves to filter any microparticle that could damage the solenoid valves and the cooler circuit, existing behind said filter disc, a nut connecting to the bottle, a connection stud provided internally with an insulating tube, which preferably will be teflonado, and a joint O-ring to connect the central body and the stud to the bottle.
En Ia parte superior del cuerpo de conexión se contempla un manómetro de presión de 100 bares, cuyo alojamiento está ventajosamente preparado, también, para alojar, en su lugar, una sonda de presión o traductor de presión para ordenador.In the upper part of the connection body a pressure gauge of 100 bars is contemplated, the housing of which is advantageously prepared, also, to house, instead, a pressure probe or pressure translator for a computer.
En Ia parte opuesta a Ia conexión a Ia botella, el cuerpo central de conexión incorpora un conector doble macho, que sirve de unión al latiguillo, mediante su acoplamiento Ia tuerca giratoria de conexión con que dicho latiguillo está provisto en sus extremos, tal como ya se ha mencionado, habiéndose previsto, en el interior del citado conector doble macho, un tubo de aislamiento teflonado.In the opposite part to the connection to the bottle, the central connection body incorporates a double male connector, which serves as a connection to the hose, by means of its coupling the rotating connecting nut with which said hose is provided at its ends, as already It has been mentioned, having been provided, inside said double male connector, a tefloned insulation tube.
Además, ortogonalmente a los elementos de conexionado aIn addition, orthogonally to the connection elements to
Ia botella y al latiguillo, el cuerpo central de conexión incorpora una válvula de purga, elemento imprescindible para el purgado y alivio de presión entre envase y enfriador, Ia cual está basada en un cierre de punzón metálico para asegurar el cierre estanco de los alivios de CO2 líquido, estando dicha válvula unida al cuerpo central mediante un conector doble macho de unión.The bottle and the hose, the central connection body incorporates a purge valve, an essential element for purging and pressure relief between container and cooler, which is based on a metal punch closure to ensure the tight seal of the relief of Liquid CO 2 , said valve being connected to the central body by means of a double male connector.
Finalmente, en el lado opuesto a Ia válvula, el cuerpo de conexión cuenta con un tapón que cierra una conexión preparada para introducir una sonda de temperatura o traductor para ordenador.Finally, on the opposite side of the valve, the connection body has a plug that closes a connection prepared to introduce a temperature probe or computer translator.
El descrito aparato enfriador de vasos u otros recipientes, perfeccionado, y conjunto de acoplamiento para Ia extracción de CO2 líquido representa, por consiguiente, una estructura innovadora de características estructurales y constitutivas desconocidas hasta ahora para tal fin, razones que unidas a su utilidad práctica, Ia dotan de fundamento suficiente para obtener el privilegio de exclusividad que se solicita.The apparatus described chiller vessels or other containers, refined, and coupling assembly for the extraction of liquid CO 2 therefore represents an innovative structure of structural and constitutive features unknown up until now for such purpose, reasons which together with its practical utility , They provide sufficient grounds to obtain the privilege of exclusivity that is requested.

De forma caracterizadora, Ia boquilla (9) pulverizadora, se encuentra dispuesta orientada boca debajo de manera que el gas enfriador que sale por sus orificios (10) se derrama sobre el vaso (6) o recipiente dispuesto bajo ella, para Io cual, el aparato (1) se configura a partir de una base (11 ) inferior, que actúa de soporte y presenta una configuración esencialmente plana, sobre Ia que se acopla, preferentemente en uno de sus lados, un cuerpo tubular (12) hueco que se prolonga en, al menos, un tramo vertical (12a) y, a cierta altura, se curva 180° en, al menos, otro tramo curvo (12b) incorporando en su extremo distal una primera campana (13) que, dispuesta boca abajo, queda elevada a cierta distancia sobre Ia antedicha base (11 ), siendo dicha distancia Ia necesaria para que entre dicha campana (13) y Ia base (11) quepa un vaso (6) u otro recipiente de dimensiones más o menos convencionales, para proceder a su enfriamiento.In a characterizing manner, the spray nozzle (9) is arranged oriented face down so that the cooling gas exiting its holes (10) spills onto the vessel (6) or container disposed thereunder, for which, the apparatus (1) is configured from a lower base (11), which acts as a support and has an essentially flat configuration, on which a hollow tubular body (12) is extended, preferably on one of its sides. in, at least, a vertical section (12a) and, at a certain height, it bends 180 ° in, at least, another curved section (12b) incorporating at its distal end a first bell (13) that, arranged upside down, remains raised at a certain distance on the above-mentioned base (11), said distance being the one necessary so that between said bell (13) and the base (11) a vessel (6) or another container of more or less conventional dimensions fits, to proceed to its cooling
Opcionalmente, se contempla Ia incorporación de un mecanismo para regular Ia distancia entre Ia citada primera campana (13) y Ia base (11), en orden a permitir su ajuste a distintos tamaños de vaso (6) o recipientes, ya sea mediante el desplazamiento vertical del cuerpo tubular (12), y consecuentemente de Ia campana (13), con un mecanismo de tipo telescópico, o bien, mediante el desplazamiento vertical de Ia zona (11a) de Ia base (11 ) en Ia que se posiciona el vaso (6) o recipiente a enfriar, por ejemplo con un mecanismo de plataforma elevable.Optionally, the incorporation of a mechanism to regulate the distance between said first bell (13) and base (11) is contemplated, in order to allow its adjustment to different vessel sizes (6) or containers, either by displacement vertical of the tubular body (12), and consequently of the bell (13), with a telescopic type mechanism, or, by vertical displacement of the area (11a) of the base (11) in which the vessel is positioned (6) or container to be cooled, for example with a lifting platform mechanism.
Siguiendo con Ia invención, el interior de Ia campana (13), que actúa de carcasa protectora, se incorporan los elementos funcionales del aparato, de tal forma que el racor (2) de conexión, que une Ia electroválvula (3) al latiguillo (4) por donde entra el gas procedente de Ia bombona de CO2, se acopla en el extremo distal del cuerpo tubular (12) y el latiguillo (4) discurre por el interior de dicho cuerpo tubular (12) para salir por debajo de Ia base (11 ) prolongándose hasta Ia bombona.Following the invention, the interior of the hood (13), which acts as a protective housing, incorporates the functional elements of the apparatus, such that the connection fitting (2), which joins the solenoid valve (3) to the hose (4) through which the gas from the CO2 cylinder enters, is coupled at the distal end of the tubular body (12) and the hose (4) runs through the inside of said tubular body (12) to exit below the base (11) extending to the cylinder.
Por su parte, Ia electroválvula (3), y el conjunto pulverizador (5), que están orientados hacia abajo, quedan alojados bajo Ia campana (13), existiendo una segunda campana (14), de menor dimensión que Ia primera campana (13), que abarca solo dicho conjunto pulverizador (5) ajustándose al borde superior del vaso (6) o recipiente a enfriar, Ia cual segunda campana (14), al mismo tiempo, protege Ia electroválvula (3) y el microcontrolador de su contacto directo con el gas.On the other hand, the solenoid valve (3), and the sprayer assembly (5), which are oriented downwards, are housed under the hood (13), there being a second bell (14), smaller in size than the first bell (13 ), which includes only said sprayer assembly (5) adjusting to the upper edge of the vessel (6) or container to be cooled, which second bell (14), at the same time, protects the solenoid valve (3) and the microcontroller from its direct contact With the gas
Por otra parte, como se aprecia en las figuras 3 a 14, el conjunto pulverizador (5), formado por el regulador de caudal (7), Ia pieza de prolongación (8) y Ia boquilla (9), presenta Ia particularidad de contar con un tubo de aislamiento (15), concretamente un tubo de tipo teflonado, para que el frío tenga Ia mínima pérdida de frigorías, el cual, como se aprecia en las figuras 6 y 14, abarca interiormente el regulador de caudal (7) y Ia pieza de prolongación (8), hasta llegar a Ia altura de Ia boquilla (9) pulverizadora o difusora de salida así como una arandela teflonada externa (21 ).On the other hand, as can be seen in figures 3 to 14, the sprayer assembly (5), formed by the flow regulator (7), the extension piece (8) and the nozzle (9), has the peculiarity of counting with an insulation tube (15), specifically a teflon type tube, so that the cold has the minimum loss of refrigerators, which, as can be seen in figures 6 and 14, internally covers the flow regulator (7) and The extension piece (8), until reaching the height of the nozzle (9) spray or diffuser outlet as well as an external teflon washer (21).
