Waste glass crushing and sorting recycling system and method

Abstract

The invention discloses a waste glass crushing and sorting recycling system. The waste glass crushing and sorting recycling system comprises a glass breaking device, a magnetic separation device, a vortex sorting device, a grinding device, a wind power sorting device and a photoelectric separation device. According to the waste glass crushing and sorting recycling system, the separation between the magnetic metal mixture, the nonferrous metal, the plastic and glass fragments of different colors in the waste glass and the decontamination operation of the glass can be simultaneously realized, the waste glass crushing and sorting recycling system has the advantages of being wide in application range, high in sorting efficiency, environmentally friendly and the like. The invention further discloses a waste glass crushing and sorting recycling method.

Description

technical field [0001] The invention relates to a waste recovery system, in particular to a waste glass crushing, sorting and recycling system and method. Background technique [0002] Due to its excellent properties and low cost, glass products play an important role in people's production and life. However, the number of scrapped glass products has also increased dramatically with economic development and population growth. Discarded glass accounts for about 5% of municipal solid waste, a huge amount. Statistics show that China produces more than 40 million tons of waste glass every year. The main component of glass is silica, which belongs to the range of basically non-degradable substances. The recycling of waste glass has become a hot issue in the field of resource regeneration. Due to the stable chemical properties of glass, landfill treatment will cause a lot of material waste and occupy land resources for a long time. A large amount of plastic and metal substance...

Problems solved by technology

Apply for a patent "Discarded Glass Medicine Bottle Crushing, Recycling, Sorting Device and Sorting Method" (Luo Junwen et al., CN106694196A) uses photoelectric sorting for the separation of materials with different attributes, without considering the sorting and sorting of different colored glasses, and the recycling technology is single, It is impossible to form the separate recovery of each component material of complex waste glass

The patent "A Waste Lamp Treatment and Recovery System" (Wei Zhengkang et al., CN105344696A) proposes a complete recycling process for waste lamp tubes, using the method of washing and decontamination to clean the glass, but does not consider that a large amount of fluorescent light will be produced during the cleaning process powdery waste water, prone to secondary pollution

The patent "A Device for Recycling Broken Glass" (Wei Fangfang, CN106984627A) and the patent "Impact Crusher for Glass Recycling" (Jiang Daguang et al., CN106513110A) focused on the improvement of the crusher, but did not change the components in the waste glass mixture. material for recycling
