Automatic material sorting system based on near infrared spectrum

Abstract

The invention discloses an automatic material sorting system based on a near infrared spectrum. The material sorting system comprises a shell (1), a conveyor belt (2), a near infrared light emitter (3), an infrared light detection probe (4), a set of nozzles (5), a gas supply pipe (6), a high-pressure air pump (7), a first material storage barrel (8), a second material storage barrel (9), a dust hood (10), a fan (11), a brush roller (12) and a material guiding mechanism (13). The material sorting system has the advantages of being efficient, energy-saving, low in material requirement, capableof identifying materials with different sizes, and high in sorting speed; and the material sorting system is environment-friendly, and according to the a dust removal device, dust generated during work is removed, and pollution of the dust to an infrared lens is reduced.

Description

technical field [0001] The invention relates to the field of material sorting, in particular to an automatic material sorting system based on near-infrared spectroscopy. Background technique [0002] In the field of solid waste disposal and recycling, if you want to sort out mixed plastics, you can only select them manually, relying on human eyes to identify them based on the differences in color and texture of the selected materials combined with experience, and then pick them out by hand. However, manual sorting has the problems of high sorting cost, low efficiency, and poor accuracy. There are also some water washing equipment, according to the density difference of the plastic, reconcile different concentrations of brine for sorting, this method produces more waste water and is not environmentally friendly. Contents of the invention [0003] The purpose of the present invention is to provide an automatic material sorting system based on near-infrared spectroscopy, bas...
