Abstract
Dispositivo para pretratar y, a continuación, transportar, plastificar o aglomerar materiales sintéticos, en particular residuos de material termoplástico para fines de reciclaje, con un recipiente (1) para el material a procesar, en el que está dispuesta al menos una herramienta de mezcla y/o de trituración (3) que gira perimetralmente en torno a un eje de rotación (10) para mezclar, calentar y, si procede, triturar el material plástico, en el que está constituido en una pared lateral (9) del recipiente (1), en la zona situada a la altura de la herramienta, o de la herramienta situada más abajo y próxima a la base, de mezcla y/o de trituración (3) un orificio (8) por el que se puede extraer el material plástico pretratado del interior del recipiente (1), estando previsto al menos un transportador de varios tornillos sinfín (5) para recoger el material pretratado, con al menos dos tornillos sinfín (6) que rotan y transportan en el interior de una carcasa (16), en particular tornillos sinfín (6) plastificantes o aglomerantes, presentando la carcasa (16) un orificio de entrada (80) situado en su lado frontal (7) o en la pared de su camisa para el material a captar por el tornillo sinfín (6), estando conectado el orificio de entrada (80) con el orificio (8), siendo los dos tornillos sinfín (6) corrotativos entre sí y pasando la prolongación imaginaria del eje longitudinal central (15) del transportador (5) o del tornillo sinfín (6) más próximo al orificio de entrada (80) junto al eje de rotación (10) sin cortarse con él en sentido contrario a la dirección de transporte (17) del transportador (5), caracterizado por que el eje longitudinal (15) del transportador (5) o del tornillo sinfín (6) más próximo al orificio de entrada (80), en el lado de descarga y en la dirección de rotación o de movimiento (12) de la herramienta de mezcla y/o de trituración (3), está desplazado a una cierta distancia (18) con respecto al radial (11) del recipiente (1) que discurre en paralelo al eje longitudinal (15) y está orientado hacia fuera con respecto al eje de rotación (10) de la herramienta de mezcla y/o de trituración (3) en la dirección de transporte (17) del transportador (5).
Description
En otra configuración especialmente ventajosa, está previsto que el recipiente colector sea básicamente cilíndrico y presente una superficie de la base plana y una pared lateral orientada en vertical con respecto a esta en forma de camisa cilíndrica. Además, desde el punto de vista de la construcción, resulta fácil que el eje de rotación coincida con el eje central del recipiente colector. En otra configuración ventajosa, está previsto que
5 el eje de rotación o el eje central del recipiente esté orientado en vertical y/o perpendicular con respecto a la superficie de la base. Con estas geometrías especiales, se optimiza el comportamiento de captación en un dispositivo estructuralmente estable y fácil de construir. En este contexto, también resulta ventajoso prever que la herramienta de mezcla y/o de trituración o - en caso de que estén previstas varias herramientas de mezcla y/o de trituración dispuestas unas sobre otras - la
10 herramienta de mezcla y/o de trituración situada más abajo y más próxima a la base, así como el orificio, estén dispuestos a corta distancia de la zona de la base, en particular en la zona del cuarto inferior de la altura del recipiente colector. La distancia se define y se mide aquí desde el borde más inferior del orificio o del orificio de entrada hasta la base del recipiente, en la zona del borde del recipiente. Puesto que el canto angular suele estar construido de forma redondeada, la distancia se mide hacia fuera desde el canto de más abajo del orificio
15 hasta la prolongación imaginaria de la base del recipiente, hacia abajo a lo largo de la prolongación imaginaria de la pared lateral. Se consideran distancias adecuadas entre 10 y 400 mm. Además, para el procesamiento es ventajoso que los cantos radialmente más exteriores de las herramientas de mezcla y/o de trituración alcancen hasta muy cerca de la pared lateral. El recipiente no tiene que presentar necesariamente una forma cilíndrica circular, si bien esta forma resulta
20 ventajosa por motivos prácticos y técnicos de producción. Las formas de recipiente que difieren de la forma cilíndrica circular, por ejemplo los recipientes con forma troncocónica o los recipientes cilíndricos con un plano elíptico u oval, deben equivaler en cuanto a capacidad volumétrica a un recipiente cilíndrico circular, suponiendo que la altura de este recipiente teórico es igual a su diámetro. Las alturas de recipiente que superan considerablemente el torbellino de mezcla que se forma aquí (teniendo en cuenta la distancia de
25 seguridad) no se tomarán en cuenta, ya que esta altura de recipiente excesiva no se utiliza y, por lo tanto, ya no influye en el procesamiento del material. Por transportador se entenderán aquí tanto instalaciones con tornillo sinfín no compresores o descompresores, es decir, tornillos sinfín puramente de transporte, como también instalaciones con tornillos sinfín compresores, es decir, tornillos sinfín de extrusor con efecto aglomerante o plastificante.
30 Por extrusor o tornillo sinfín de extrusor se entenderán en el presente texto tanto los extrusores y tornillos sinfín con los que el material se funde parcial o totalmente, como también los extrusores con los que el material ablandado únicamente se aglomera pero no se funde. En los tornillos sinfín aglomerantes, el material únicamente se comprime y se corta rápida y fuertemente, pero no se plastifica. Por lo tanto, el tornillo sinfín aglomerante proporciona a su salida material que no está completamente fundido, sino que solo está
35 compuesto de partículas fundidas en su superficie y que se ha aglutinado de forma similar que en una sinterización. En ambos casos, sin embargo, con el tornillo sinfín se ejerce presión sobre el material y se compacta. De la descripción de los siguientes ejemplos de ejecución del objeto de la invención, que no deben entenderse como restrictivos, se derivan otras características y ventajas representadas en los dibujos de forma
40 esquemática y no a escala:
La fig. 1 muestra una sección vertical a través de un dispositivo según la invención con un extrusor conectado más o menos tangencialmente con tornillos sinfín superpuestos. La fig. 2 muestra una sección horizontal a través de una forma de ejecución alternativa con un extrusor
45 conectado más o menos tangencialmente con tornillos sinfín cilíndricos colocados uno junto al otro en paralelo. La fig. 3 muestra otra forma de ejecución con un desplazamiento mínimo del extrusor. La fig. 4 muestra otra forma de ejecución con un desplazamiento mayor del extrusor.
Ni los recipientes ni los tornillos sinfín o las herramientas de mezcla están representados a escala en los
50 dibujos, ni en sí, ni unos respecto a otros. Por ejemplo, en la realidad los recipientes son generalmente más grandes o los tornillos sinfín más largos de lo aquí representado. Las combinaciones de compresor de corte-extrusor representadas desde distintas posiciones en la fig. 1 y fig. 2 son muy parecidas en cuanto a estructura y, por ello, se describen a continuación conjuntamente. Se distinguen sobre todo en la colocación de los tornillos sinfín entre sí, que se abordará más adelante con mayor
55 detalle. Las ventajosas combinaciones de compresor de corte-extrusor representadas en las figs. 1 y 2 para el tratamiento o reciclaje de material plástico presentan respectivamente un recipiente o compresor de corte o despedazador 1 cilíndrico circular con una superficie de la base 2 plana horizontal y una pared lateral 9 vertical orientada en perpendicular con respecto a ella, en forma de camisa cilíndrica.
60 A corta distancia de la superficie de la base 2, como máximo a aproximadamente entre el 10 y el 20%, si procede menos, de la altura de la pared lateral 9 – medido desde la superficie de la base 2 hasta el borde superior de la pared lateral 9 – está dispuesto un disco portante o un portaherramientas 13 plano, orientado en
