High-throughput intelligent sorting method and system for recovering waste plastic

Abstract

The invention discloses a high-throughput intelligent sorting method for recovering waste plastic. The method comprises the following steps that (1) a high-throughput intelligent sorting system is arranged, and screening manipulators are sequentially arranged from top to bottom in a layered manner from a hopper to form a multi-layer infrared screening production line; (2) the recovered mixed waste plastic fragments are conveyed to all infrared screening manipulators for spectrum recognition sorting and sorting; (3) the step (2) is repeated, the recovered mixed waste plastic fragments are sequentially fed into all the infrared screening manipulators to complete a first sorting cycle; (4) subsequent sorting circulation is carried out on the remaining unrecognized mixed waste plastic until all the waste plastic is sorted; and (5) the single-component waste plastic is enabled to be separately used for subsequent regeneration processing. The invention further discloses a high-throughput intelligent sorting system for implementing the method. According to the high-throughput intelligent sorting method and system, equipment and labor investment for recovering and reproducing the waste plastic can be greatly reduced, and the requirements of large scale and low cost are met.

Description

technical field [0001] The invention relates to the technical field of spectral identification and recycling of waste plastics, in particular to a high-throughput intelligent sorting method and system for recycling plastics. Background technique [0002] As a widely used chemical product, plastic brings convenience to human's daily life, but at the same time, due to its own weakness of being difficult to degrade, it brings great challenges to the global environment and environmental protection requirements. If waste plastics are not disposed properly, it will cause serious environmental pollution and other problems, and at the same time cause a huge waste of resources. The recycling of waste plastics is an important way to solve the problem of waste plastics, and the sorting of waste plastics is a crucial link in recycling and the premise of realizing the efficient and high value-added utilization of plastics. Sorting, purification and regeneration of waste plastics can imp...

Problems solved by technology

However, these methods have more or less disadvantages such as high energy consumption, low degree of automation, low efficiency, poor accuracy, and secondary pollution, and it is difficult to adapt to the large-scale and low-cost development needs of the modern recycling industry.

[0004] The near-infrared spectrum sorting technology is a new technology that has emerged in recent years, but there are still many technical difficulties in applying it to the field of waste plastic recycling technology and achieving the goal of high efficiency and low cost.
