A device for separating and recycling waste liquid crystal display glass and polarizers

Abstract

The invention discloses equipment used for separating and recovering glass and polaroids of a waste liquid crystal display. The equipment comprises a water storage tank, a water injection pipe, a motor, a main separation tank, a stirrer, a polaroid enrichment tank, a glass collection tank, a polaroid collection tank and a horizontal platform face. On the foundation of keeping physicochemical characteristics of materials, the equipment achieves separation and recovery of the glass and the polaroids based on difference of physical characteristics of materials and under the action of a separating medium. The separating medium is tap water, is clean and is recycling. The equipment has the advantages of being environmentally friendly, efficient, flexible, easy and convenient to operate, low in investment cost, small in occupied space and the like, thereby being suitable for resource recycling of the glass and the polaroids of the waste liquid crystal display.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and relates to electronic waste treatment equipment, in particular to physical treatment equipment for resource separation and recovery of valuable materials from waste liquid crystal display panels, and is suitable for resource treatment of waste liquid crystal display panels. Background technique [0002] 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 the waste liquid crystal display is discarded directly into the environment without proper disposal, the liquid crystal and heavy metals contained in it will easily pose a threat to the environment and human health; at the same time, the liquid crystal display also contains plastic, glass, metal indium, etc., which can be recycle...

AI Technical Summary

Problems solved by technology

If the waste liquid crystal display is discarded directly into the environment without proper disposal, the liquid crystal and heavy metals contained in it will easily pose a threat to the environment and human health; at the same time, the liquid crystal display also contains plastic, glass, metal indium, etc., which can be recycled Direct disposal of recycled materials is also a waste of resources, so how to scientifically and effectively dispose of waste LCD screens has become an increasingly important social and environmental issue

[0003] Among the current processing technologies for liquid crystal display screens, chemical technologies such as incineration and pyrolysis are widely used to separate and recycle organic matter and glass and other materials, and to regenerate resources. While consuming a lot of energy, they are also likely to cause secondary pollution to the environment.
