Background
In recent years, with the economic development, the use of motor vehicles is gradually increased, and the large amount of waste generated by scrapped motor vehicles generates huge burden and pollution to the environment ecology. After these waste motor vehicles are disassembled and crushed to recover valuable materials, nearly 30% of the difficult-to-recover residues, commonly referred to as "waste motor vehicle crushed residues (ASR), contain, for example, foamed cotton, plastic, rubber, fiber, metal, glass, dust and other impurities.
It is known to recover the residues of the waste motor vehicle after crushing, to screen out combustibles and to produce solid waste Derived Fuel (RDF-5) to convert the waste into renewable energy.
In the known art, a forming process for producing a derived fuel from waste raw materials comprises the following steps: screening out a raw material with a preset size; feeding the screened raw materials into a heating unit through a conveyor to gradually heat and melt the raw materials, wherein the heating time is about 1 to 2 hours, so that the raw materials are in a molten state; cutting off a heat source, uniformly stirring the molten raw materials and cooling; and cooling and then sending the mixture into a granulating (extruding) machine for granulating (extruding) and forming.
That is, the extrusion apparatus requires an additional heating unit to be used in conjunction with the derived fuel. In other industries, the extrusion apparatus is required to be equipped with a heating unit in order to soften various raw materials for the secondary solid plastic molding.
