Complex sorting system and complex sorting method for sorting automobile shredder residue using trommel

Abstract

The purpose of the present invention is to separate automobile shredder residue into uniform particle sizes and thereby solve the problem of overloading a crushing unit and a vacuum suction device, and to separate the automobile shredder residue by particle size to increase fiber fluff removal efficiency. The present invention provides a complex sorting system for sorting automobile shredder residue using a trommel, the complex sorting system comprising: a first trommel which separates the automobile shredder residue into particles having an average particle size of 30 mm or less and particles having an average particle size over 30 mm; a first magnetic sorting unit which receives the particles having an average particle size over 30 mm separated by the first trommel, and separates same into magnetic products and non-magnetic products; a first crushing unit which receives and crushes the separated non-magnetic products to form first crushed products; a plurality of blown air sorting units which receive the first crushed products, separate same into high-weight products and low-weight products, and discharge the low-weight products; a sorting unit which receives the high-weight products from the blown air sorting units, crushes same, and classifies the crushed high-weight products into particles having an average particle size of 5 mm or less, particles having an average particle size of 5 to 12 mm, and particles having an average particle size of 12 to 20 mm; and an output unit which receives the particles having an average particle size of 5 mm or less to collect conductive metal particles, receives the particles having an average particle size of 5 to 12 mm and the particles having an average particle size of 12 to 20 mm to collect nonferrous metals, and discharges polyvinyl chloride (PVC).

Description

technical field [0001] The present invention relates to a composite sorting system and a composite sorting method for scrapped automobile residues using a drum screen, and in more detail, to the following composite sorting system and a composite sorting method for scrapped automobile residues using a drum screen, that is, by Scrapped car residues are sieved to a homogeneous particle size to reduce the load of the crushing process and vacuum suction process and improve the removal efficiency of fiber fluff. Background technique [0002] With the expansion of the scale of the automobile industry, the environmental pollution caused by end-of-life vehicles (ELV, End of Life Vehicle) is gradually becoming the focus of social attention. Therefore, various countries are working to minimize pollution and recycle resources through stricter regulations. Maximize the system. [0003] At present, among scrapped vehicle shredding products, although iron fragments and non-ferrous metals ...

Problems solved by technology

Although incineration and landfilling of solid industrial waste that can be reduced in volume by incineration is usually carried out, the incineration or landfill of scrapped vehicle residues not only reduces the recycling rate of scrapped vehicles, but also causes insufficient landfills and environmental problems. issues such as pollution, therefore, technologies for recycling are currently required

[0006] So far, although a technology for standardizing ELV residues to a size below the specified reference particle size has been developed, this technology not only has the problem of non-uniform particle size of the standardized ELV residues, but also has The load on the process is increased, and the removal efficiency of fiber fluff and the recovery efficiency of metals in the overall process are reduced.
