Embodiment Construction

[0039] see figure 1 , the industrialized recycling method of the glass panel of the waste liquid crystal display in the present embodiment is to operate according to the following steps:

[0040] 1. Disassemble the liquid crystal display, take out the LCD glass panel, open the LCD glass panel by mechanical trimming, wash and remove the liquid crystal with a cleaning agent, and obtain two clean glass substrates 1, and clean the glass by hand or with a vacuum suction plate. The substrate 1 is placed on the horizontal conveyor belt 3 with the side where the film layer is located facing up;

[0041]2. With the conveyance of the horizontal conveyer belt 3, when the glass substrate 1 passes under the grinding wheel, the film layer on the glass substrate 1 is ground by the grinding wheel, so that the film layer on the glass substrate 1 The film layer is separated from the glass substrate, and the film layer wear debris 6 is collected; the film layer wear debris 6 is collected by air...

Abstract

The invention discloses an industrialized recovery method and an apparatus of a waste liquid crystal display (LCD) glass panel. The recovery method comprises following steps: a glass substrate is placed on a conveyor belt, with the surface where a membrane is arranged being upward, and self-locking and positioning of the glass substrate are realized by the static friction force between the glass substrate and the conveyor belt; the LCD glass substrate and the membrane are separated from each other by grinding, grinding dust is collected to obtain indium metallurgy raw materials; and at last the grinded glass substrate is crushed, immersed in an organic solvent and centrifuged successively, so that classification collection of glass and a polaroid is realized. The recovery method is simple and practical, can be industrialized, is high in efficiency, and can be used for classification collection of waste liquid crystal display glass panel with high quality.

Description

[0001] This application is a divisional application with the application number 2012101228586, the application date is April 24, 2012, and the title of the invention is a method and device for industrialized recycling of glass panels of waste liquid crystal displays. technical field [0002] The present invention relates to a method and device for industrialized recycling of glass panels of waste liquid crystal displays, more specifically, to display panels of discarded liquid crystal televisions, liquid crystal computers, mobile phones, portable game machines, or waste products produced during the production process A method and device for sorting and recycling metal materials, glass and polarizers in glass panels. Background technique [0003] The distribution of indium in the earth's crust is small and scattered, and there is no separate deposit. It is dispersed in minerals of other elements (lead, zinc, copper, tin minerals) with impurity components, and is produced as a ...
