Description
Dispositivo de reglaje para paladares aplicable en molinos de áridos o minerales.Applicable adjustment device for palates in aggregate or mineral mills.
La presente invención se refiere, tal como expresa el enunciado de la presente memoria descriptiva, a un dispositivo de reglaje para paladares aplicable en molinos de áridos o minerales.The present invention relates, as expresses the statement of the present specification, to a adjustment device for palates applicable in mills aggregates or minerals.
De forma más concreta, el dispositivo que propugna la presente invención pretende regular de forma rápida, fácil y segura, la distancia entre las mandíbulas de los paladares y las barras del rotor del molino, a fin de conseguir el grado de granulometria deseado.More specifically, the device that advocates the present invention aims to regulate quickly, easy and safe, the distance between the jaws of the palates and the mill rotor bars, in order to achieve the degree of Desired granulometry
Como es sabido, los molinos de trituración por impacto, incorporan un rotor, convenientemente motorizado, del que emergen en disposición aproximadamente radial una pluralidad de barras destinadas a actuar sobre los productos a triturar.As is known, crushing mills by impact, they incorporate a rotor, conveniently motorized, from which a plurality of bars intended to act on the products to be crushed.
Una serie de mandíbulas pertenecientes a paladares dispuestos en forma envolvente alrededor de dicho rotor, actúan como sufrideras, de manera que en función del distanciamiento existente entre el borde operativo de las barras y las mandíbulas, se consigue una granulometria específica a la salida del molino, siendo necesario ajustar esa distancia por el operario.A series of jaws belonging to palates arranged in an envelope around said rotor, they act as sufrideras, so that depending on the distance between the operating edge of the bars and the jaws, you get a specific granulometry to the mill exit, being necessary to adjust that distance by the operator.
En referencia al estado de la técnica, debe mencionarse que en tales molinos, los paladares se hallan unidos solidariamente a unos tensores que a su vez están abrochados a una barra o balancín transversal provisto de dispositivos deslizantes en sus extremos que discurren sobre sendas guías fijas solidarias a la carcasa del molino, contando para el desplazamiento de dicho conjunto, y por consiguiente de los paladares, con el auxilio de un pistón.In reference to the state of the art, you must mention that in such mills, palates are united in solidarity with some tensioners that in turn are fastened to a bar or transverse rocker equipped with sliding devices at its extremes that run on fixed solidarity guides to the mill housing, counting for the displacement of said set, and therefore of the palates, with the help of a piston.
Una vez alcanzada la posición adecuada, el balancín transversal, es fijado a las guías fijas mediante un tornillo de apriete o método similar, montado sobre los mencionados dispositivos deslizantes de sus extremos, presionando dichos tornillos sobre las guías fijas.Once the appropriate position is reached, the transverse rocker arm, is fixed to the fixed guides by means of a tightening screw or similar method, mounted on those mentioned sliding devices at their ends, pressing said screws on the fixed guides.
Este sistema de fijación tiene como principal inconveniente, debido a la gran fuerza de empuje que ha de soportar la barra transversal, que cuando el molino trabaja tiende a desplazarse, ya que mediante tornillería se realiza una fijación basada en la adherencia del balancín deslizante sobre una corredera y con esta fijación, debido a la fuerza ejercida por el molino al trabajar o por vibraciones indeseadas que aflojan los tornillos de sujeción, no se consigue una fijación perfecta.This fixing system has as main inconvenient, due to the great thrust force it has to withstand the crossbar, which when the mill works tends to move, since by means of fasteners a fixation is made based on the adhesion of the sliding rocker on a slide and with this fixation, due to the force exerted by the mill at work or by unwanted vibrations that loosen the screws of clamping, perfect fixation is not achieved.
Por otra parte, dicha operación representa mucha dificultad para el operario que ha de ajustar y manipular el paladar del molino, para conseguir un buen apriete y posterior soltura del tornillo, con la consiguiente pérdida de tiempo necesario para ello.Moreover, said operation represents much difficulty for the operator who has to adjust and manipulate the palate of the mill, to get a good tightening and subsequent looseness of the screw, with the consequent loss of time necessary for it.
En orden a subsanar tales inconvenientes, se propone la presente invención, haciendo el peticionario de la misma expresa mención de que desconoce la existencia de un dispositivo de reglaje para paladares aplicable en molinos de áridos o minerales que presente unas características técnicas, estructurales y constitutivas semejantes.In order to remedy such inconveniences, proposes the present invention, making the petitioner thereof express mention that he is unaware of the existence of a device adjustment for palates applicable in aggregate or mineral mills that has technical, structural and similar constitutive.
Con la presente invención se ha ideado por tanto, tal como se ha mencionado, un dispositivo de reglaje para paladares aplicable en molinos de áridos o minerales, cuyo objetivo principal radica en la sustitución de la fijación de la distancia entre las mandíbulas de los paladares y las barras del rotor, mediante el atornillado de la barra transversal a las guías fijas solidarias a la carcasa, por un innovador sistema de fijación, gracias al cual, de forma rápida, fácil y sobre todo segura, se consigue el total enclavamiento del conjunto evitando cualquier desplazamiento involuntario del mismo a causa de la fuerza ejercida por el molino al trabajar, o por las vibraciones indeseadas.With the present invention it has been devised by both, as mentioned, a setting device for palates applicable in aggregate or mineral mills, whose objective main lies in the replacement of the distance setting between the jaws of the palates and the rotor bars, by screwing the crossbar to the fixed guides solidarity with the housing, for an innovative fixing system, thanks to which, quickly, easily and especially safely, it get the total interlocking of the set avoiding any involuntary displacement due to the force exerted by the mill when working, or by unwanted vibrations.
Para ello, el dispositivo según la invención, tanto en las guías fijas como en los dispositivos deslizantes de los extremos de la barra transversal, incorpora una pluralidad de orificios, estando dispuestos los orificios de las guías fijas en su alineación vertical, de forma alternativa.For this, the device according to the invention, both in the fixed guides and in the sliding devices of the ends of the crossbar, incorporates a plurality of holes, the holes of the fixed guides being arranged in its vertical alignment, alternatively.
Gracias a su especial disposición, al efectuar pequeños desplazamientos de la barra transversal, va coincidiendo un orificio de los dispositivos deslizantes de la barra transversal con algún orificio de las guías fijas, produciéndose dichas coincidencias en saltos discretos, pero de valor aproximadamente constante y determinado.Thanks to your special disposition, when making small displacements of the crossbar, coincides a hole in the sliders of the crossbar with some hole in the fixed guides, producing said coincidences in discrete jumps, but of approximately value constant and determined.
El enclavamiento de este conjunto se realiza mediante la introducción de un bulón en los únicos orificios que hayan coincidido de la guía fija y del dispositivo deslizante. Lo antedicho es igualmente aplicable al dispositivo deslizante simétrico del otro extremo de la barra transversal, donde también se introducirá un bulón en los únicos orificios que coincidan.The interlocking of this set is done by introducing a bolt in the only holes that have coincided with the fixed guide and the sliding device. The above is equally applicable to the sliding device symmetrical from the other end of the crossbar, where also a bolt will be inserted into the only holes that match.
De esta forma, mediante la sustitución del sistema de enclavamiento de la barra de sujeción de los paladares de los molinos, sustituyendo los tradicionales tornillos de apriete, por el conjunto de orificios efectuados en las guías y en los dispositivos deslizantes y el bulón que se introduce en ellos, se consigue una fijación rápida y segura.In this way, by replacing the interlocking system of the clamping bar of the palates of the mills, replacing the traditional screws of tighten, by the set of holes made in the guides and in the sliding devices and the bolt that goes into them, fast and secure fixation is achieved.
El nuevo dispositivo de reglaje para paladares aplicable en molinos de áridos o minerales representa, por consiguiente, una estructura innovadora de características estructurales y constitutivas desconocidas hasta ahora para tal fin, razones que unidas a su utilidad práctica, le dotan de fundamento suficiente para obtener el privilegio de exclusividad que se solicita.The new adjustment device for palates applicable in aggregate or mineral mills represents, by consequently, an innovative structure of features structural and constitutive unknown so far for such end, reasons that together with its practical utility, endow it with sufficient basis to obtain the privilege of exclusivity that is requested.
Para complementar la descripción que se está realizando y con objeto de ayudar a una mejor comprensión de las características de la invención, se acompaña a la presente memoria descriptiva, como parte integrante de la misma, de una hoja de planos, en la cual con carácter ilustrativo y no limitativo se ha representado lo siguiente:To complement the description that is being performing and in order to help a better understanding of the characteristics of the invention, is attached herein descriptive, as an integral part of it, of a sheet of planes, in which with an illustrative and non-limiting nature it has been represented the following:
La figura número 1.- Muestra una vista esquemática de la estructura de un molino al que se ha aplicado el dispositivo de la invención.Figure number 1.- Shows a view schematic of the structure of a mill to which the device of the invention.
La figura número 2.- Muestra una vista en perspectiva del dispositivo según la invención.Figure number 2.- Shows a view in perspective of the device according to the invention.
La figura número 3.- Muestra una vista en perspectiva lateral y ampliada del dispositivo.Figure number 3.- Shows a view in lateral and enlarged perspective of the device.
A la vista de las comentadas figuras y de acuerdo con la numeración adoptada, se puede observar en las mismas un ejemplo de realización preferente del dispositivo de reglaje para paladares aplicable en molinos de áridos o minerales que comprende las partes indicadas a continuación.In view of the commented figures and of according to the numbering adopted, it can be observed in them a preferred embodiment of the adjustment device for palates applicable in aggregate or mineral mills that It includes the parts indicated below.
Así, tal y como puede observarse en dichas figuras, los paladares (2) del molino (1) se hallan unidos de forma solidaria a los tensores (3) abrochados preferentemente mediante tornillos (4) a una barra transversal (5), disponiendo de un muelle de amortiguamiento (6), provista de sendos dispositivos deslizantes (7) en sus extremos.Thus, as can be seen in these figures, the palates (2) of the mill (1) are joined together attached to the tensioners (3) fastened preferably by screws (4) to a crossbar (5), having a spring damping (6), provided with two devices sliders (7) at their ends.
Dichos dispositivos deslizantes (7) discurren respectivamente sobre sendas guías fijas (8), que se encuentra unidas solidariamente a la carcasa (9) del molino (1), contando para el desplazamiento de dicho conjunto, y por consiguiente de los paladares (2), con el auxilio de un pistón (10).Said sliding devices (7) run respectively on paths fixed guides (8), which is united in solidarity with the housing (9) of the mill (1), counting for the displacement of said set, and consequently of the palates (2), with the help of a piston (10).
Las mencionadas guías fijas (8) presentan una pluralidad de orificios (11) dispuestos en una o más filas paralelas, preferentemente dos, una superior (11a) y otra inferior (11b), de forma que la alineación de los orificios en sentido vertical, de una y otra fila, sea alternada y distanciados unos de otros de forma determinada en función de las necesidades de granulometría del molino en cada caso.The aforementioned fixed guides (8) have a plurality of holes (11) arranged in one or more rows parallel, preferably two, one upper (11a) and one lower (11b), so that the alignment of the holes in the direction vertical, from one row to another, be alternated and distanced from each other others in a certain way depending on the needs of mill granulometry in each case.
Por su parte, ambos dispositivos deslizantes (7) situados en los extremos de la barra transversal (5) presentan igualmente una pluralidad de orificios (12) de idéntico o parecido tamaño, dispuestos igualmente en una o dos filas (12a) y (12b) alineados horizontalmente con las filas (11a) y (11b) de orificios de las guías fijas (8)On the other hand, both sliding devices (7) located at the ends of the crossbar (5) have also a plurality of holes (12) of identical or similar size, also arranged in one or two rows (12a) and (12b) aligned horizontally with rows (11a) and (11b) of holes of the fixed guides (8)
De esta forma, y debido a esta disposición, al desplazarse la barra transversal (5), los orificios (12) de los dispositivos deslizantes (7) van coincidiendo de forma alternativa con los orificios (11) de la fila superior (11a) y de la fila inferior (11b) de las guías fijas (8), produciéndose dichas coincidencias en saltos discretos, pero de valor aproximadamente constante y determinado.In this way, and due to this provision, the move the crossbar (5), the holes (12) of the Sliding devices (7) are matched alternately with the holes (11) of the upper row (11a) and the row bottom (11b) of the fixed guides (8), producing said coincidences in discrete jumps, but of approximately value constant and determined.
Cabe señalar, que la distancia existente entre todos los orificios (11) de cada una de las dos filas (11a) y (11b) de la barra fija (8) es aproximadamente constante para los orificios de cada fila, pero es distinta a la distancia que existe entre los orificios (12) de cada una de las dos filas (12a) y (12b) de la pieza deslizante (7). De esta forma, se consigue que según se va desplazando la pieza (7) solo coincidirá un orificio de todos los existentes en dicha pieza con uno de los existentes en la pieza (8) que es donde se introducirá el bulón (13) de sujeción, y el resto de los orificios de ambas piezas no coincidirá. Con ello se consigue que en las diversas coincidencias posibles de dos orificios, se produzcan muchas posiciones de enclavamiento, en saltos discretos, pero de valor aproximadamente constante y determinado, tal como ya se ha mencionado.It should be noted that the distance between all holes (11) of each of the two rows (11a) and (11b) of the fixed bar (8) is approximately constant for holes in each row, but it is different from the distance that exists between the holes (12) of each of the two rows (12a) and (12b) of the sliding piece (7). In this way, you get that as the piece (7) moves, only one hole will coincide all existing in said piece with one of those existing in the piece (8) which is where the clamp bolt (13) will be introduced, and the rest of the holes of both pieces will not match. With that it is achieved that in the various possible coincidences of two holes, many interlocking positions occur, in discrete jumps, but of approximately constant value and determined, as already mentioned.
Se entiende, que lo antedicho es igualmente aplicable a las piezas (7) y (8) simétricas, del otro extremo de la barra transversal (5), donde también se introducirá un bulón (13) en los únicos orificios que coincidan.It is understood that the above is also applicable to symmetrical parts (7) and (8), from the other end of the crossbar (5), where a bolt (13) will also be introduced in the only holes that match.
Una vez regulado el espacio entre el rotor y el paladar, la barra transversal (5), es fijada a las guías fijas (8) mediante la introducción, como ya se ha dicho de un bulón (13) de dimensiones adecuadas, en cada uno de los dispositivos deslizantes (7), en los orificios (12) de estos que hayan coincidido con los orificios (11) de las correspondientes guías fijas (8).Once the space between the rotor and the palate, the crossbar (5), is fixed to the fixed guides (8) by introducing, as already said of a bolt (13) of suitable dimensions, in each of the sliding devices (7), in the holes (12) of these that have coincided with the holes (11) of the corresponding fixed guides (8).
Descrita suficientemente la naturaleza de la presente invención, así como la manera de ponerla en práctica, se hace constar que, dentro de su esencialidad, podrá ser llevada a la práctica en otras formas de realización que difieran en detalle de la indicada a título de ejemplo, y a las cuales alcanzará igualmente la protección que se recaba siempre que no se altere, cambie o modifique su principio fundamental.Describe sufficiently the nature of the The present invention, as well as how to implement it, is it states that, within its essentiality, it may be taken to the practice in other embodiments that differ in detail from the one indicated by way of example, and which will reach also the protection that is collected as long as it is not altered, change or modify its fundamental principle.
