| description | A high accuracy rapid system for sorting a plurality of waste products by polymer type. The invention involves the application of Raman spectroscopy and complex identification techniques to identify and sort post-consumer plastics for recycling. The invention reads information unique to the molecular structure of the materials to be sorted to identify their chemical compositions and uses rapid high volume sorting techniques to sort them into product streams at commercially viable throughput rates. The system employs a laser diode (20) for irradiating the material sample (10), a spectrograph (50) is used to determine the Raman spectrum of the material sample (10) and a microprocessor based controller (70) is employed to identify the polymer type of the material sample (10).
La présente invention concerne un système rapide à haute précision permettant de trier une pluralité de déchets par type de polymère. La présente invention implique l'application de techniques de spectroscopie Raman et d'identification complexes permettant d'identifier et de trier des plastiques post-consommation de façon à les recycler. Le système lit des informations spécifiques à la structure moléculaire des matériaux à trier de façon à identifier leurs compositions chimiques et utilise des techniques rapides de triage de gros volumes de manière à les trier en flux de produits à des taux de production commercialement rentables. Le système utilise une diode laser (20) pour irradier l'échantillon (10) de matériau, un spectrographe (50) pour déterminer le spectre Raman de l'échantillon (10) et un organe de commande articulé autour d'un microprocessor (70) pour identifier le type de polymère de l'échantillon (10) de matériau. |
