Description

Technical Field

[0001] The utility model relates to the technical field of material sorting in a refrigerator disassembling line, and in particular to a material sorting device and system for a refrigerator disassembling line. Background Art

[0002] With the acceleration of the replacement of household appliances, the number of used refrigerators is increasing, and their disassembly and recycling have become an important part of environmental protection and resource reuse.

[0003] Currently, the material sorting process on refrigerator disassembly lines primarily involves running the crushed waste refrigerators through an eddy current nonferrous metal separator to separate the non-metallic and metallic materials, and then using a gravity separator to separate the copper and aluminum from the metallic materials. However, current separation devices only separate metals and non-metals from all crushed materials and cannot separate materials of different volumes. This results in poor purity when the gravity separator separates the copper and aluminum. Some separation devices also use eddy current separation to separate the copper and aluminum, then use a screen to separate the metallic materials by volume, and then perform gravity separation to separate the copper and aluminum. While this method can improve the purity of the copper and aluminum separation to a certain extent, it increases the number of separation steps and processes, resulting in low separation efficiency and increased equipment installation space.

[0004] In the relevant technologies, there are many steps in sorting materials for refrigerator disassembly, low purity of copper and aluminum sorting, and low sorting efficiency. No effective solutions have been proposed yet. Utility Model Content
