DESCRIPCIONDESCRIPTION

TamizSieve

La invencion se refiere a un tamiz con el cual, pero no exclusivamente, se separan elementos en forma de banda y en forma de placa del material a cribar, por ejemplo durante la separacion de basura casera o basura triturada, correspondiente al preambulo de la reivindicacion 1.The invention relates to a screen with which, but not exclusively, band-shaped and plate-shaped elements are separated from the material to be screened, for example during the separation of homemade garbage or crushed garbage, corresponding to the preamble of the claim. one.

Durante el cribado de mezclas inhomogeneas de materiales sucede frecuentemente que partes particularmente largas, por tanto en forma de banda, o en forma de hoja, por ejemplo en forma de plancha, impiden el transporte del material a lo largo de la direccion de criba y llevan a la formacion de acumulaciones de material, que tras alcanzar un tamano cntico se enrollan sobre amplias zonas del tamiz, sin ser por ello cribados; estas partes del material a cribar tambien tienden a cubrir una parte considerable de aberturas del tamiz durante largos espacios de tiempo y con ello a perjudicar la calidad de la criba. En este campo tecnico deben mencionarse en particular los siguientes documentos:During the screening of inhomogeneous mixtures of materials it is often the case that particularly long parts, therefore in the form of a band, or in the form of a sheet, for example in the form of an iron, prevent the transport of the material along the direction of the screen and carry to the formation of accumulations of material, which after reaching a critical size are rolled over large areas of the sieve, without being screened; These parts of the material to be screened also tend to cover a considerable part of sieve openings for long periods of time and thereby impair the quality of the sieve. In this technical field, the following documents must be mentioned in particular:

Documento DE 10 2009 007 823: Este tamiz tiene como contenido la problematica especial de, en una construccion facil y una alta capacidad de separacion de la instalacion, hacer facil y realizable la adaptacion de la separacion y la inclinacion y la sustitucion de las laminas de separacion. Como laminas de separacion se designan en este caso planchas dobladas, que esencialmente transcurren transversalmente a la direccion de criba entre planchas longitudinales, y que en su zona superior, que entra en contacto primero con el material que se va a cribar, estan configuradas al menos aproximadamente paralelas al plano de criba, con su seccion claramente colocada bajo el plano de criba, pero configuradas esencialmente mas pendientes. En este caso la curvatura hacia el material a cribar es concava.Document DE 10 2009 007 823: This sieve has as its content the special problem of, in an easy construction and a high capacity of separation of the installation, to make easy and feasible the adaptation of the separation and the inclination and the replacement of the sheets of separation. As separating sheets are designated in this case folded plates, which essentially run transversely to the direction of screening between longitudinal plates, and which in their upper area, which first comes into contact with the material to be screened, are configured at least approximately parallel to the screen plane, with its section clearly placed under the screen plane, but configured essentially more slopes. In this case the curvature towards the material to be screened is concave.

Del documento EP 2 196 081 de la solicitante se conoce un tamiz que esta pensado concretamente en particular para formar tamanos de malla relativamente pequenos, pero no se limita a esto. En este tamiz las nervaduras que transcurren en planos verticales a traves de la direccion de criba, estan provistas de escotaduras rodeadas por todas partes de material de nervadura, en las que se introducen perfiles que corresponden a las laminas de separacion del documento mencionado anteriormente. Estos perfiles pueden presentar una seccion transversal curvada o plegada, en este caso la curvatura esta realizada igual que en el documento mencionado anteriormente. El objetivo de esta medida es llegar, tambien en tamanos de malla pequenos, en los que ya no es posible un soldado de los perfiles con las nervaduras, a configuraciones mecanicamente estables.From the document EP 2 196 081 of the applicant a screen is known which is specifically designed in particular to form relatively small mesh sizes, but is not limited to this. In this sieve the ribs that run in vertical planes through the sieve direction, are provided with recesses surrounded by all parts of rib material, in which profiles corresponding to the separation sheets of the aforementioned document are introduced. These profiles may have a curved or folded cross section, in this case the curvature is made in the same way as in the document mentioned above. The objective of this measure is to arrive, also in small mesh sizes, in which it is no longer possible to weld the profiles with the ribs, to mechanically stable configurations.

Del documento AT 509 855 de la solicitante se conoce otro tamiz, en el cual las nervaduras que transcurren en la direccion de criba presentan ranuras sobre su lado inferior, en las que se introducen perfiles que presentan ranuras en su lado superior. Los perfiles estan nuevamente plegados o curvados, como en ambos documentos anteriores, pero aqrn aun esta previsto un liston sobre el lado superior de cada nervadura que, visto transversalmente a la direccion de criba, es mas grueso que la nervadura, por lo que preferiblemente los perfiles en su canto superior presentan escotaduras configuradas de forma que el liston esta situado al menos parcialmente bajo la superficie de las zonas de los perfiles que transcurren paralelas o aproximadamente paralelas al plano del tamiz.Another document is known from document AT 509 855 of the applicant, in which the ribs that pass in the direction of the screen have grooves on its lower side, in which profiles are introduced that have grooves on its upper side. The profiles are again folded or curved, as in both previous documents, but here a ribbon is still provided on the upper side of each rib that, seen transversely to the direction of the screen, is thicker than the rib, so preferably profiles in its upper edge have recesses configured so that the bar is located at least partially below the surface of the areas of the profiles that run parallel or approximately parallel to the plane of the screen.

Ademas para la mejora de la separacion de elementos planos del flujo de material, en cribas en las que la malla de criba, vista en la direccion de criba, esta escalonada hacia abajo, se sabe colocar en la zona de cada escalon barras en forma de dedo, que transcurren por encima de la siguiente superficie de criba y cubren a esta al menos en un tercio de la longitud del escalon correspondiente. Con ello debe evitarse que elementos planos o tambien en forma de banda cubran las aberturas de criba en una proporcion considerable y asf limiten tanto la calidad de la criba como la de rendimiento.In addition to improving the separation of flat elements from the material flow, in screens in which the screen mesh, seen in the direction of the screen, is staggered downwards, it is known to place bars in the form of each step. finger, which run over the next sieve surface and cover it at least one third of the corresponding step length. This should avoid that flat or band-shaped elements cover the screen openings in a considerable proportion and thus limit both the quality of the sieve and the performance.

Las medidas mencionadas contribuyen concretamente a la mejora de la calidad de la criba y con ello tambien al aumento del posible rendimiento, sin embargo estas mejoras son solo graduales y al igual que antes, no satisfactorias. Es la tarea de la invencion el conseguir un tamiz del tipo mencionado al principio en el que los problemas mencionados se mejoren claramente hasta ser eliminados.The mentioned measures contribute specifically to the improvement of the quality of the sieve and with it also to the increase of the possible yield, however these improvements are only gradual and, as before, not satisfactory. It is the task of the invention to obtain a screen of the type mentioned at the beginning in which the mentioned problems are clearly improved until they are eliminated.

Segun la invencion esto sucede con las caractensticas mencionadas en la parte caracterizadora de la reivindicacion 1. En otras palabras, sorprendentemente es suficiente si las nervaduras del tamiz en su totalidad estan configuradas en al menos un 30% del ancho de la malla, preferiblemente en al menos un 50% del ancho de la malla y especialmente preferido en un 100% del ancho de la malla por encima de la parte de los perfiles que transcurre en la direccion de criba; en una realizacion preferida, los cantos superiores de las nervaduras estan configurados o provistos de perfiles doblados hacia arriba. Ademas los perfiles transcurren segun la invencion curvados, con un radio de curvatura de al menos 30% del ancho de la malla, preferiblemente de al menos el 60% del ancho de la malla y especialmente preferido de al menos el 100% del ancho de la malla, y presentan tangentes finales superiores, que estan situadas en el plano del tamiz. Secciones de borde rectas pueden conectar sin dobleces a uno o ambos extremos.According to the invention this happens with the characteristics mentioned in the characterizing part of claim 1. In other words, it is surprisingly sufficient if the ribs of the sieve as a whole are configured in at least 30% of the width of the mesh, preferably in the minus 50% of the width of the mesh and especially preferred at 100% of the width of the mesh above the part of the profiles that passes in the direction of screening; In a preferred embodiment, the upper edges of the ribs are configured or provided with profiles bent upwards. Also the profiles run according to the invention curved, with a radius of curvature of at least 30% of the width of the mesh, preferably at least 60% of the width of the mesh and especially preferred of at least 100% of the width of the mesh, and have upper end tangents, which are located in the sieve plane. Straight edge sections can connect without bends to one or both ends.

la Figura 1 un tamiz segun la invencion en seccion perpendicular a la superficie de criba y paralelo a la direccion de criba para la representacion de las proporciones de tamano mas importantes, la Figura 2 una vista esquematica de varios tamices colocados unos tras otros, las Figuras 3 a 6 detalles.Figure 1 a sieve according to the invention in section perpendicular to the screen surface and parallel to the screen direction for the representation of the most important size proportions, Figure 2 a schematic view of several sieves placed one after the other, the Figures 3 to 6 details.

La Figura 1 muestra una seccion esquematica, puramente esquematica, y sin cualquier representacion del marco, de la transmision o del alojamiento del tamiz, en direccion vertical paralela a la direccion de criba S entre dos nervaduras 2 que transcurren paralelas a la direccion de criba, por tanto a traves de los perfiles 3, y con esto una vista lateral de la nervadura 2 colocada tras la seccion. El tamiz esta representado sin la disposicion inclinada habitual.Figure 1 shows a schematic section, purely schematic, and without any representation of the frame, of the transmission or of the sieve housing, in a vertical direction parallel to the direction of screen S between two ribs 2 that run parallel to the direction of the screen, therefore through the profiles 3, and with this a side view of the rib 2 placed after the section. The screen is represented without the usual inclined arrangement.

El ancho de malla M del tamiz esta dado por medio de las separaciones de engrosamientos contiguos de la nervadura 2, o de listones 4 (Figura 6) y perfiles 3 contiguos, estas separaciones son en general igual de grandes, si no, para los propositos de la invencion, se aproxima como ancho de malla M la media aritmetica de ambos valores de separacion. Este ancho de malla M requiere ahora segun la invencion diferentes tamanos, medidas y relaciones del tamiz, para poder alcanzar los objetivos mencionados inicialmente: los perfiles 3 presentan en su zona superior preferiblemente una zona recta o seccion 5, en el cual termina una zona o seccion 6 curvada. Segun la invencion la seccion 5 recta y la seccion 6 curvada se conectan sin doblez una en la otra, si no hay prevista ninguna seccion 5 recta, la seccion 6 curvada termina en su zona superior en el punto final con una tangente, en la que transcurrina la seccion recta, si entonces estuviera prevista. En otras palabras, las tangentes superiores de los perfiles 3 estan dispuestas todas juntas en un plano, que en la solicitud se considera como plano 7 de criba, y que en otra consideracion, transcurre al menos paralelo a un plano de tamiz definido de otra forma.The mesh width M of the sieve is given by means of the adjacent thickening separations of the rib 2, or of slats 4 (Figure 6) and contiguous profiles 3, these separations are generally equally large, if not, for the purposes of the invention, the arithmetic mean of both separation values is approximated as the mesh width. This mesh width M now requires according to the invention different sizes, measurements and relationships of the sieve, in order to achieve the objectives mentioned initially: the profiles 3 preferably have a straight zone or section 5 in their upper zone, in which an area or section 6 curved. According to the invention the straight section 5 and the curved section 6 are connected without bending one in the other, if no straight section 5 is provided, the curved section 6 ends in its upper zone at the end point with a tangent, in which the straight section will pass, if then it was planned. In other words, the upper tangents of the profiles 3 are all arranged together in one plane, which in the application is considered as screen 7, and in another consideration, runs at least parallel to a sieve plane defined in another way. .

La zona 6 curvada de los perfiles 3 muestra en cada posicion un radio de curvatura R, el cual, como se indica arriba, supone al menos el 30% (o al menos el 60% o al menos el 100%) del ancho de la malla M. Cuando la curvatura no es constante, esto vale para cada seccion y las secciones individuales de curvaturas diferentes pasan de unas a otras sin doblez.The curved zone 6 of the profiles 3 shows in each position a radius of curvature R, which, as indicated above, represents at least 30% (or at least 60% or at least 100%) of the width of the M mesh. When the curvature is not constant, this applies to each section and the individual sections of different curvatures pass from one to the other without bending.

En el ejemplo de realizacion representado, sobre la seccion 6 curvada termina hacia “abajo” una seccion o zona recta 9, por medio de la cual puede seguirse mejorando la criba. Cuando esta prevista una seccion 9 recta de ese tipo, es esencial que termine sin doblez sobre la seccion curvada 6.In the exemplary embodiment shown, a straight section or zone 9 ends "down" on the curved section 6, by means of which the screen can be further improved. When such a straight section 9 is provided, it is essential that it end without bending over the curved section 6.

Las nervaduras 2, en las que los perfiles 3 o bien se introducen en ranuras, o sobre las cuales se fijan adecuadamente, preferiblemente soldados, sobresalen claramente sobre la superficie 7 de criba, segun se definio arriba, esta elevacion H supone al menos el 30% del ancho de la malla M, preferiblemente el 50% del ancho de la malla M y especialmente preferido es que sea mayor del 100% del ancho de la malla M. Ademas las nervaduras 2 presentan a lo largo de su canto superior un engrosamiento, el cual o bien por medio de una deformacion plastica del material de la nervadura o bien, lo que se prefiere por motivos de costes, por medio de una aplicacion, preferiblemente soldado, realiza un liston 4, donde el liston, como se representa en la Figura 6, en la direccion perpendicular al plano de la nervadura 2, por tanto en la lmea de vision en la Figura 1, presenta un espesor D, que supone al menos el doble, preferiblemente el triple, y especialmente preferido al menos el cuadruple del espesor d de la nervadura. Ademas, como se muestra en las Figuras 3-5, se prefiere que la seccion transversal del liston 4 al menos a lo largo de su contorno superior, es decir desde su posicion mas gruesa a lo largo del penmetro, que esta alejado de la nervadura 2, este configurada lisa, es decir no presente ningun doblez, por tanto este configurada redonda, preferiblemente circular o elfptica. Para la configuracion elfptica se prefiere la aplicacion elfptica transversal, como se representa en la Figura 3.The ribs 2, in which the profiles 3 are either inserted into grooves, or on which they are properly fixed, preferably welded, protrude clearly on the screen surface 7, as defined above, this elevation H is at least 30 % of the width of the M mesh, preferably 50% of the width of the M mesh and especially preferred is that it be greater than 100% of the width of the M mesh. In addition, the ribs 2 show a thickening along their upper edge, which either by means of a plastic deformation of the material of the rib or, which is preferred for reasons of cost, by means of an application, preferably welded, makes a lath 4, where the lath, as represented in the Figure 6, in the direction perpendicular to the plane of the rib 2, therefore in the vision line in Figure 1, has a thickness D, which is at least double, preferably triple, and especially preferred at least the quadruple of the thick r d of the rib. In addition, as shown in Figures 3-5, it is preferred that the cross section of the slat 4 at least along its upper contour, that is to say from its thickest position along the penimeter, which is far from the rib 2, this configured smooth, that is to say no fold present, therefore this configured round, preferably circular or elliptical. For the elliptical configuration, the transverse elliptical application is preferred, as shown in Figure 3.

La Figura 2 muestra la disposicion de dos (de varios) tamices 1 segun la invencion uno tras otro, donde los planos 7 de criba que transcurren inclinados con los tamices, no estan dispuestos alineados unos con otros, sino que en el tamiz siguiente en la direccion de criba S estan colocados respectivamente mas profundos (en el ejemplo de realizacion mostrado paralelos entre sf) que en el tamiz anterior. Aqrn pueden reconocerse bien los dedos 8 mencionados inicialmente, que aun estan dispuestos claramente por encima de los listones 4. Estos dedos 8 pueden presentar separaciones entre sf, que se corresponden con el ancho de la malla, pero tambien es posible, proporcionar estos dedos con una mayor separacion entre sf La posicion angular de los dedos en relacion al plano 7 de criba esta situada entre horizontal y paralela al plano de criba. Se prefiere la posicion dibujada, inclinada aproximadamente (+10%) la mitad frente a la horizontalidad que el plano de criba.Figure 2 shows the arrangement of two (of several) sieves 1 according to the invention one after another, where the sieve planes 7 that run inclined with the sieves, are not arranged aligned with each other, but in the next sieve in the Screen direction S are placed respectively deeper (in the embodiment shown parallel to each other) than in the previous screen. Aqrn can be recognized well the fingers 8 mentioned initially, which are still clearly arranged above the slats 4. These fingers 8 can have separations between them, which correspond to the width of the mesh, but it is also possible to provide these fingers with a greater separation between sf The angular position of the fingers in relation to the screen plane 7 is located between horizontal and parallel to the screen plane. The position drawn is preferred, inclined approximately (+ 10%) half as opposed to the horizontal as the screen plane.

En la Figura 2 se indican tambien dos angulos cuya observancia (valor absoluto, por tanto como escalar) hace aun mas efectivos los tamices segun la invencion. Se trata del angulo Y, que incluye el plano 7 del tamiz con la horizontal, y el angulo X, que incluye la tangente del extremo inferior de la seccion 6 curva - y por tanto una zona 9 recta inferior de los perfiles prevista eventualmente - con la horizontal. Ahora se prefiere que el angulo X corresponda al menos a 1,5 veces, preferiblemente al doble y especialmente preferido al triple del angulo Y.In Figure 2 two angles are also indicated whose observance (absolute value, therefore as scalar) makes sieves even more effective according to the invention. It is the angle Y, which includes the plane 7 of the screen with the horizontal, and the angle X, which includes the tangent of the lower end of the curved section 6 - and therefore a lower straight zone 9 of the profiles provided eventually - with the horizontal It is now preferred that the angle X corresponds to at least 1.5 times, preferably twice and especially preferred three times the angle Y.

La invencion no esta limitada a los ejemplos de realizacion representados y descritos, sino que puede modificarse repetidamente. Como se indica en la Figura 2, es posible combinar entre sf varios elementos de criba segun la invencion, no solo, como esta representado, en serie, sino tambien de manera que se consigan varias cubiertas deThe invention is not limited to the embodiments shown and described, but may be modified repeatedly. As indicated in Figure 2, it is possible to combine several sieve elements according to the invention, not only, as shown, in series, but also in such a way that several covers of
