Background
The natural degradation time of common glass and products thereof is as long as 4000 years, heavy metal elements are added into part of the glass in the processing process, the glass possibly causes irreversible influence on soil and water when entering the environment, and waste glass cannot be treated and disposed by traditional modes such as burning, landfill and the like. Therefore, recycling is a better treatment mode for the waste glass at present. China has a mature technology in the aspect of waste glass recycling technology, and various recycling methods and devices are more and more practical. Before recycling, the waste glass with different sources, complex shapes, various types and different compositions is classified and sorted through a sorting step.
The current common sorting methods mainly comprise manual sorting and mechanical sorting. Among them, manual sorting requires a lot of labor, and is also prone to cause problems such as injury and pollution during sorting, and has been gradually replaced by mechanical sorting. For example, the chinese patent application CN204485991U discloses a glass crushing and sorting device, which physically sorts and cleans the impurities in the waste glass, such as paper scraps, plastic fragments, stones, etc. which are not beneficial to the subsequent processing of the glass, by the combination of a crusher, a magnet, a vibrating screen and a suction fan; chinese patent application CN203044366U discloses an optical sorting device for recycling colored waste glass, which can sort waste glass with different optical characteristics by using different reflection characteristics of the surfaces of different colored glass and using optoelectronic components as the recognition core. However, at present, most of waste glass is usually required to be in a shape or size meeting the requirements of a specific process before being recycled, and no better method for sorting the shape and size of the glass is available for replacing manual sorting.
