Embodiment Construction

[0038] 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:

[0039] 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;

[0040] 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 ai...

Abstract

The invention discloses an industrialized recovery method and a recovery device for a glass panel of a waste liquid crystal display. The industrialized recovery method is characterized by comprising the steps of placing glass substrate on a conveying belt, with the surface a coating located on being upward; realizing self-locking and positioning of the glass substrate by virtue of static friction force between the glass substrate and the conveying belt; separating the glass substrate of the LCD (Liquid Crystal Display) from the coating by grinding; collecting grindings, thereby obtaining indium metallurgical materials; and finally conducting smashing, soaking in organic solvent, and centrifugal separation on the ground glass substrate, thereby sorting and recycling glass and polaroids. The recovery method and the recovery device are simple, practical and available for sorting and recovering the glass panel of the waste liquid crystal display, in an industrialized, high-efficient and high-quality way.

Description

technical field [0001] 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 [0002] 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 by-product of their smelting. Relevant data show that the world's proven indium mineral reserves are only 16,000 tons, which is one-sixth of gold reserves. ITO coated glass is the largest user of indium, accounting for 49%-55% of indium consumption, and is widely used...
