Abstract

Przedmiotem zgłoszenia jest sposób odzysku odpadów wielkogabarytowych, prowadzący do wydzielenia odpadów złomu metalicznego o wysokiej czystości, gdzie odpady wielkogabarytowe po wstępnym rozdrobnieniu korzystnie do frakcji poniżej 20 mm na rozdrabniaczu wstępnym dwuwałowym (2) poddawane są klasyfikacji powietrznej (2) na frakcje lekką i ciężką. Frakcja lekka zawiera głównie tkaniny, gąbkę i tworzywa sztuczne, które następnie poddawane są klasyfikacji na separatorze magnetycznym lub elektromagnetycznym (3). Lekka frakcja niemagnetyczna poddawana jest na klasyfikatorze balistycznym (4) na elementy 2D (płaskie) i 3D (toczące się). Frakcja ciężka wydzielona na klasyfikatorze powietrznym (2) oraz lekka frakcja magnetyczna wydzielona przez separator magnetyczny lub elektromagnetyczny (3) poddawana jest doczyszczeniu w młynie elektromagnetycznym (5) wyposażonym w mielniki, których zadaniem jest oczyszczenie elementów metalowych z zanieczyszczeń niemetalicznych (farby, lakiery, tynki, drewno, tworzywa). Sposób według zgłoszenia polega na wydzieleniu ze strumienia odpadów wielkobarytowych czystego złomu metalicznego i charakteryzuje się tym, że doczyszczanie złomu prowadzi się z wykorzystaniem młyna elektromagnetycznego o średnicy roboczej minimum 300 mm i mielników o długości nie większej niż 40 mm, a także całkowicie rezygnuje się ze wstępnego demontażu i ręcznej selekcji odpadów wielkogabarytowych.The subject of the application is a method of recovery of large-size waste, leading to the separation of high-purity metal scrap waste, where the large-size waste, after initial shredding, preferably to fractions below 20 mm on a two-shaft pre-shredder (2), is subjected to air classification (2) into light and heavy fractions. The light fraction mainly contains fabrics, sponge and plastics, which are then classified on a magnetic or electromagnetic separator (3). The light non-magnetic fraction is processed on a ballistic classifier (4) into 2D (flat) and 3D (rolling) elements. The heavy fraction separated by the air classifier (2) and the light magnetic fraction separated by a magnetic or electromagnetic separator (3) are subjected to further cleaning in an electromagnetic mill (5) equipped with grinding media whose task is to clean metal elements from non-metallic impurities (paints, varnishes, plasters). , wood, plastics). The method according to the application consists in separating clean metal scrap from the bulk waste stream and is characterized by the fact that scrap cleaning is carried out using an electromagnetic mill with a working diameter of at least 300 mm and grinding media with a length of not more than 40 mm, and the preliminary cleaning is completely omitted. dismantling and manual selection of large-sized waste.
