Description

Criba para clasificar residuos sólidos.Screen to classify solid waste.

La presente invención se refiere al sector de los procesos de cribado y clasificación y se refiere en particular a una criba nueva para clasificar residuos sólidos.The present invention relates to the sector of screening and classification processes and refers in particular to a new sieve to classify solid waste.

Actualmente se usan varios tipos de cribas, principalmente cribas de red metálica y cribas con rodillos con placas, tales como la que se da a conocer en el documento DE-U-297 11 724.Several types of screens are currently used, mainly metal net screens and roller screens with plates, such as the one disclosed in the document DE-U-297 11 724.

Las cribas de red metálica comprenden una red con mallas de tamaño creciente, a través de las cuales cae secuencialmente el material a cribar. Los objetos más pequeños pasan a través de la red, es decir, caen en primer lugar, en el área con mallas más finas, mientras que los objetos más grandes caen en las áreas sucesivas, en las que la red tiene mallas más grandes.Metal grid screens comprise a network with meshes of increasing size, through which it falls sequentially the material to be screened. The smallest objects they pass through the network, that is, they fall first, in the area with finer meshes, while larger objects fall into successive areas, in which the network has more meshes big.

Las cribas de red metálica resultan caras debido al hecho de que la red experimenta una acción de rozamiento y se desgasta de forma bastante rápida, y además requieren un sistema de avance del material.Metal grid screens are expensive because to the fact that the network experiences a friction action and it wears quite quickly, and also require a system of material advance.

Las cribas con rodillos con placas comprenden una serie de rodillos paralelos, estando constituido cada uno de ellos por un eje con placas fijadas al mismo.Screen rollers with plates comprise a series of parallel rollers, each being constituted by an axis with plates fixed to it.

El paso entre los rodillos y entre las placas del mismo rodillo puede ser constante o creciente.The passage between the rollers and between the plates of the Same roller can be constant or growing.

Todos los rodillos se sitúan en rotación al mismo tiempo y en la misma dirección. El área superior de cada rodillo gira hacia los rodillos que están más separados y que tienen las placas más separadas.All rollers are rotated to it Time and in the same direction. The upper area of each roller rotates towards the rollers that are more separated and that have the more separate plates.

Los objetos a cribar se sitúan sobre los primeros rodillos con un paso reducido, los cuales proporcionan el transporte de los mismos hacia los rodillos con un paso aumentado. A lo largo de su recorrido, los objetos más pequeños caen en los espacios entre rodillos y placas, mientras que los objetos con un tamaño mayor pasan a través de los sucesivos rodillos y placas.The objects to be screened are placed on the first rollers with a reduced pitch, which provide the transporting them to the rollers with an increased step. Throughout their journey, smaller objects fall into the spaces between rollers and plates, while objects with a larger size pass through successive rollers and plates.

Hasta el momento, las cribas con rodillos con placas se han usado para cribar objetos sólidos, por ejemplo, piedras, pero no se han usado de forma amplia para el cribado de residuos sólidos urbanos o materiales similares, ya que los objetos finos y largos, como las bolsas, se enrollan alrededor de los rodillos, atascándolos y obstruyendo los espacios entre los rodillos y entre las placas, lo cual evidentemente hace que el proceso de cribado resulte inútil.So far, roller screens with plates have been used to screen solid objects, for example, stones, but have not been widely used for screening solid urban waste or similar materials, since objects thin and long, like the bags, are wrapped around the rollers, jamming them and obstructing the spaces between the rollers and between the plates, which obviously makes the screening process is useless.

Para eliminar los inconvenientes mencionados anteriormente, se ha diseñado e implementado un nuevo tipo de criba para clasificar residuos sólidos urbanos.To eliminate the mentioned inconveniences previously, a new type of screen has been designed and implemented to classify urban solid waste.

La nueva criba de clasificación comprende, en sus partes principales, un armazón de soporte y alineación, un conjunto de rodillos con placas y elementos antiobstrucción.The new classification screen includes, in its main parts, a support and alignment frame, a set of rollers with plates and anti-obstruction elements.

El armazón está constituido por varias partes metálicas y tiene la función de sostener y alinear todos los rodillos, de contener el material a cribar y de cubrir todos los órganos que transmiten movimiento a los rodillos. El armazón aloja los diversos rodillos, los cuales son paralelos entre sí y cuyo paso puede ser constante o creciente en la dirección de avance del material a cribar.The framework is made up of several parts metallic and has the function of holding and aligning all rollers, containing the material to be screened and covering all organs that transmit movement to the rollers. The frame houses the various rollers, which are parallel to each other and whose step may be constant or increasing in the direction of advance of the material to be screened.

Los rodillos comprenden un eje principal con placas perpendiculares fijadas al mismo. Entre las diversas placas, alrededor de los ejes, se disponen unos elementos antiobstrucción constituidos por tubos cilíndricos movibles cuyo diámetro es mayor que el correspondiente al eje.The rollers comprise a main shaft with perpendicular plates fixed to it. Between the various plates, around the axes, anti-obstruction elements are arranged constituted by movable cylindrical tubes whose diameter is greater than the one corresponding to the axis.

Las placas pueden presentar cualquier forma, es decir, pueden ser circulares, elípticas, triangulares, cuadriláteras, pentagonales, hexagonales, etcétera.The plates can have any shape, it is that is, they can be circular, elliptical, triangular, quadrilaterals, pentagonal, hexagonal, etc.

El borde de cada placa está provisto de una tira metálica perpendicular a la propia placa, de manera que la sección de la placa tiene forma de una doble T.The edge of each plate is provided with a strip metal perpendicular to the plate itself, so that the section of the plate is shaped like a double T.

Como alternativa, en el borde de la placa se puede aplicar una tira doble en ángulo e inclinada hacia el centro de la placa, de manera que la sección de la propia placa presente la forma de una flecha doble.Alternatively, at the edge of the plate you you can apply a double strip angled and inclined towards the center of the plate, so that the section of the plate itself presents The shape of a double arrow.

Como variante adicional de la invención, el borde de la placa también puede estar provisto de dos tiras laterales dispuestas a lo largo del diámetro de la placa y de forma perpendicular a la misma, en lugar de la tira inclinada doble. Estas tiras dobles pueden ser poligonales, como la propia placa, o anulares.As a further variant of the invention, the edge of the plate can also be provided with two side strips arranged along the plate diameter and shape perpendicular to it, instead of the double inclined strip. These double strips can be polygonal, like the plate itself, or annular

Si la placa es circular o elíptica, la tira o las tiras tienen la forma correspondiente a un anillo curvado, mientras que si la placa es poligonal la tira tiene forma de anillo poligonal, formado por varias secciones planas que son tan largas como el lado de la placa/polígono.If the plate is circular or elliptical, the strip or strips have the shape corresponding to a curved ring, while that if the plate is polygonal, the strip is shaped like a ring polygonal, consisting of several flat sections that are so long as the side of the plate / polygon.

Las diversas placas están fijadas al eje del rodillo, de manera que la superficie de la placa es perpendicular a la longitud del eje.The various plates are fixed to the axis of the roller, so that the surface of the plate is perpendicular to shaft length

Los elementos antiobstrucción están insertados alrededor del eje, entre cada par de placas de cada rodillo.The anti-obstruction elements are inserted around the axis, between each pair of plates of each roller.

Cada elemento antiobstrucción comprende un tubo cilíndrico cuyo diámetro es mayor que el eje del rodillo y cuya longitud es sustancialmente idéntica a la distancia entre dos placas contiguas del rodillo.Each anti-obstruction element comprises a tube cylindrical whose diameter is larger than the axis of the roller and whose length is substantially identical to the distance between two adjoining roller plates.

A diferencia de las placas, los tubos cilíndricos antiobstrucción no están fijados a los rodillos, sino que simplemente rodean la sección del eje incluida entre dos placas y son libres para girar alrededor del eje de los rodillos.Unlike plates, cylindrical tubes Anti-obstruction are not fixed to the rollers, but rather simply surround the shaft section included between two plates and They are free to rotate around the axis of the rollers.

Las placas y/o los tubos cilíndricos antiobstrucción pueden estar realizados con metal, plástico o cualquier otro material adecuado.The plates and / or the cylindrical tubes Anti-obstruction can be made with metal, plastic or Any other suitable material.

El paso entre las diversas placas en los rodillos puede ser el mismo para todos los rodillos o puede aumentar comenzando por los primeros rodillos hacia los rodillos finales a lo largo del recorrido de los objetos a cribar.The passage between the various plates in the rollers it can be the same for all rollers or it can increase starting with the first rollers towards the final rollers to along the route of the objects to be screened.

El plano constituido por los diversos rodillos puede ser fijo con respecto al armazón o inclinable por medio de mecanismos hidráulicos, de tal manera que se optimice el proceso de cribado.The plane constituted by the various rollers can be fixed with respect to the frame or tiltable by means of hydraulic mechanisms, in such a way that the process of optimization is optimized screening.

La velocidad de rotación de los rodillos es fijada por el operario y puede ser constante, o puede variar en todos los rodillos, o puede variar según la posición de los rodillos en el inicio, en el centro o al final del recorrido del material a cribar.The speed of rotation of the rollers is set by the operator and may be constant, or may vary in all rollers, or may vary depending on the position of the rollers at the beginning, in the center or at the end of the material to be screened.

La criba de clasificación constituida tal como se ha descrito anteriormente posibilita la clasificación de residuos sólidos sin ningún problema, ya que los tubos cilíndricos proporcionados en los rodillos y las tiras presentes en los bordes de las placas evitan el enrollamiento y enredamiento de objetos finos y/o largos y/o elementos similares. La forma poligonal especial de las placas y la tira presente en los bordes de las placas facilita el avance del material a cribar que, debido a su tamaño, no puede pasar entre los rodillos con menos separación.The screening screen constituted as described above enables the classification of waste solids without any problem, since the cylindrical tubes provided on rollers and strips present at the edges of the plates prevent the curl and entanglement of objects fine and / or long and / or similar elements. Polygonal shape special of the plates and the strip present at the edges of the plates facilitates the advance of the material to be screened which, due to its size, can not pass between the rollers with less separation.

La nueva criba de clasificación se puede usar para cualquier residuo con una consistencia adecuada, como residuos sólidos urbanos, residuos industriales de los sectores de la carpintería, el plástico, textil, residuos agrícolas como compost, algas, hierba y en general materiales sueltos.The new classification screen can be used for any residue with adequate consistency, such as waste urban solids, industrial waste from the sectors of the carpentry, plastic, textile, agricultural waste such as compost, seaweed, grass and loose materials in general.
