Back plate removing device of retired photovoltaic module

Abstract

The invention discloses a back plate removing device for a retired photovoltaic module. The back plate removing device for a retired photovoltaic module comprises a rack, a material conveying mechanism, a grinding mechanism and a lifting mechanism, wherein the material conveying mechanism is movably fixed on the rack along the vertical direction and is used for bearing and conveying the retired photovoltaic module, the grinding mechanism and the lifting mechanism are fixed on and below the material conveying mechanism correspondingly, the lifting mechanism is connected with the bottom of the material conveying mechanism and moves the material conveying mechanism in the vertical direction, and the grinding mechanism and the material conveying mechanism are arranged in a spaced mode, which is used for making contact with the retired photovoltaic module on the surface of the material conveying mechanism after the material conveying mechanism moves upwards and grinding a back plate locatedon the upper surface of the retired photovoltaic module. According to the back plate removing device of the retired photovoltaic module, on the premise that waste gas and waste liquid are not generated, the back plate is firstly removed, the photovoltaic module can be favorably recycled through a mechanical treatment method, and the environment is well protected.

Description

technical field [0001] The invention relates to the technical field of photovoltaic module recycling, in particular to a device for removing a back plate of a decommissioned photovoltaic module. Background technique [0002] Photovoltaic modules contain eight major materials, namely solar silicon cells, tempered glass, packaging materials (such as EVA, that is, ethylene-vinyl acetate copolymer; POE, that is, polyethylene octene co-elastomer), photovoltaic backplane (fluorine-containing plastics) ), copper-tin soldering strips, silica gel, junction boxes, and aluminum alloy frames. The materials are mostly interlayer structures for auxiliary lamination, providing conditions for step-by-step separation and recycling. [0003] According to the public data of the National Energy Administration of China, as of 2018, the installed capacity of photovoltaic modules in the world has reached 500GWp, and the installed capacity of photovoltaic power generation in my country has reached ...

AI Technical Summary

Problems solved by technology

[0004] The specific recovery and treatment methods of photovoltaic modules reported publicly include inorganic acid dissolution method, organic solvent dissolution method, heat treatment method, mechanical treatment method and mixed method, but the recovery of photovoltaic modules by chemical and heat treatment methods is very easy to produce highly polluting waste gas and waste liquid, therefore, how to effectively mechanically peel off the various components of photovoltaic modules has become a hot spot and difficulty in the recycling of photovoltaic modules
