Abstract

System to recycle waste from foamed thermoplastics and reduce their volume in the same proportion as their density is increased; which comprises using: - a conveyor for foamed thermoplastic waste. - the material is transported to a hopper of a ripper of material to whose exit the material, which does not have the size, is separated by the action of a sieve. The rest is transported to a detector-separator that selects it, and it is collected in appropriate containers. - the material suitable for the process is used to feed a vis-without-end to the output from which the material is subjected to a melting and compaction operation. - once properly compacted, the material is driven and transported by the action of air inside pipes connected to separators that cause small particles to come out, while the rest of the material is conducted and collected in containers.

Description

Sistema para reciclar residuos de termo-plásticos espumados y reducir el volumen de los mismos en la misma proporción que se aumenta su densidad.Waste recycling system Foamed thermoplastics and reduce the volume of the same in the same proportion that increases its density.

Objeto de la invenciónObject of the invention

La presente invención se refiere a un sistema para reciclar residuos de termoplásticos espumados y reducir el volumen de los mismos en la misma proporción que se aumenta su densidad.The present invention relates to a system to recycle foamed thermoplastic waste and reduce volume of them in the same proportion that increases their density.

Antecedentes de la invenciónBackground of the invention

Los termoplásticos espumados presentan como una de sus múltiples aplicaciones la de utilizarse como embalaje y como complemento, a veces, de los embalajes de cartón, en los productos sensibles al impacto.Foamed thermoplastics present as a of its multiple applications to be used as packaging and as a complement, sometimes, of cardboard packaging, in impact sensitive products.

En la aplicación general de estos productos como embalajes se conforman por moldeado, son resistentes y amortiguan los impactos, son aislantes al calor, y sobre todo presentan un reducido peso.In the general application of these products as  packaging is shaped by molded, resistant and cushioned the impacts are heat insulating, and above all they have a reduced weight

Estas y otras ventajas que son inherentes a esta clase de plásticos tienen un inconveniente importante que es el de ocupar un volumen elevado respecto a su propia densidad, inconveniente fundamental en su transporte, siendo antieconómico para su reciclado, y por otra parte cuando se utiliza como combustible este tipo de material presenta un reducido poder calorífico y produce gases, los cuales, para no contaminar, hay que tratarlos, incrementando el coste como combustible.These and other advantages that are inherent in this  plastics class have a major drawback that is that of occupy a high volume with respect to its own density, fundamental inconvenience in its transport, being uneconomic for recycling, and on the other hand when used as fuel this type of material has a reduced power calorific and produces gases, which, in order not to contaminate, there are to treat them, increasing the cost as fuel.

Estos problemas se solucionan con el sistema de la invención que hace posible reciclar el termoplástico espumado y su posterior utilización de forma económica, aprovechando la materia prima del termoplástico para aplicaciones ulteriores como termoplástico.These problems are solved with the system of the invention that makes it possible to recycle the foamed thermoplastic and its subsequent use economically, taking advantage of the Thermoplastic raw material for further applications such as thermoplastic

Descripción de la invenciónDescription of the invention

El sistema de la invención presenta las siguientes ventajas:The system of the invention presents the following advantages:

- En el lugar donde se producen los desperdicios, se reducen el volumen de los mismos entre 15 y 50 veces, incrementando en la misma proporción su densidad.- In the place where the waste, reduce the volume of them between 15 and 50 times, increasing in the same proportion its density.

- La operación de reducir su volumen se efectúa en la unidad autónoma y auto-transportada, facilitando su recogida en el sitio que se produce, o se desee.- The operation to reduce its volume is carried out in the autonomous and self-transported unit, facilitating its collection on the site that is produced, or desired.

- La densidad, pasa de 10 a 65 kilogramos/metro cúbico a 500 kilogramos/metro cúbico aproximadamente dependiendo de la forma del desperdicio y del tipo de material termo-plástico.- Density, goes from 10 to 65 kilograms / meter cubic at 500 kilograms / cubic meter approximately depending on the shape of the waste and the type of material thermoplastic

- Reducción total de contaminación, ya que el reciclado, por reducción de volumen, no produce gases, trabajando de forma funcional y ecológica, ahorrando consumo de energía, al poder reciclar y emplear un material que para su obtención se empleó energía y materiales procedentes de residuos fósiles, como el petróleo.- Total pollution reduction, since the Recycled, by volume reduction, does not produce gases, working in a functional and ecological way, saving energy consumption, by be able to recycle and use a material that is obtained for used energy and materials from fossil waste, such as the oil.

El sistema consiste en disponer lo residuos de termoplásticos espumados sobre una cinta transportadora en la que se detecta y se separan los metales que pueden llevar los plásticos.The system consists of disposing the waste of thermoplastics foamed on a conveyor belt in which it detects and separates the metals that can carry the plastics

Los materiales termoplásticos espumados se elevan por medio una cinta transportadora, que suministra material a una tolva de un desgarrador, preferentemente mecánico, que vierte el material tratado a una cinta transportadora en la que hay un separador de materiales para homogeneizar la recogida en cuyo transportador se separan también los materiales no adecuados para el proceso, que se recogen en un depósito apropiado.Foamed thermoplastic materials are They raise a conveyor belt, which supplies material to a hopper of a ripper, preferably mechanical, that pours the material treated to a conveyor belt in which there is a material separator to homogenize the collection in whose conveyor materials are also separated not suitable for the process, which are collected in an appropriate deposit.

En este punto o zona se separan por aire o por otro procedimiento, aquellos materiales no apropiados a utilizar en el propio sistema.At this point or zone they are separated by air or by another procedure, those materials not appropriate to use in The system itself.

El material resultante pasa por un vis-sin-fin y es conducido hacía un punto en el que se produce por fusión y compactación la conformación de este material que en forma de trozos filiformes de grosor y tamaño apropiados para ser transportado y conducido por medio de aire y a través de conducciones hacía grandes recipientes de malla de plástico, o cartón en los que se recoge el material compactado, después de que previamente se hayan separado las posibles partículas pequeñas de material.The resulting material goes through a vis-endless and is led to a point at which fusion and compaction occurs the conformation of this material that in the form of filiform pieces of appropriate thickness and size to be transported and driven by medium of air and through pipes to large containers of plastic mesh, or cardboard in which the material is collected compacted, after previously separating the Possible small particles of material.

En la entrada del material a la tolva del desgarrador aparece una especie de envolvente en la que se recogen los posibles gases espumantes, pasando por un filtro de carbón activo absorbente, para retenerlos, en caso de necesidad.At the entrance of the material to the hopper of the heartbreaking appears a kind of envelope in which they are collected the possible foaming gases, passing through a carbon filter absorbent active, to retain them, if necessary.

Por último sistema disponer de un refrigerador que regula y controla la temperatura de fusión del material.Finally, have a refrigerator which regulates and controls the melting temperature of the material.
