Abstract

The invention discloses a method and a device for recovering a glass substrate and a polarizing film in a waste liquid crystal screen. The method mainly comprises a series of treatment procedures of preheating, crushing, winnowing, flotation and the like of the waste liquid crystal screen; and the device is mainly formed by sequentially arranging a heating box, a crusher and a flotation machine according to the procedures. According to the method and the device, the waste liquid crystal screen can be recycled in a large-scale, high-efficiency, high-flotation-rate, green and harmless mode, theeffect of efficiently and harmlessly separating the glass substrate and the polarizing film in the waste liquid crystal screen is achieved, conditions are created for further green application of theglass substrate and the polarizing film, and meanwhile the problem that in the prior art, environment pollution is serious is solved.

Description

technical field [0001] The invention belongs to the technical field of electronic waste treatment, and in particular relates to a method and a device for recycling glass substrates and polarizing films in waste liquid crystal screens. Background technique [0002] At present, liquid crystal displays are widely used in fields such as liquid crystal displays, liquid crystal televisions, notebook computers, tablet computers, and mobile phones. The advantages of LCD screens are low power consumption, small size, and low radiation. With the widespread application of liquid crystal displays in various electronic devices and the end of product use functions, a large number of electronic devices containing liquid crystal displays enter the waste stream to be urgently disposed of. If waste LCD screens are discarded directly into the environment without proper disposal, the liquid crystals and heavy metals contained in them will easily pose a threat to the environment and human healt...
