Embodiment 1

[0047] like figure 1 As shown, the equipment of the present invention includes a first feeding device 101, a shearing device, a second feeding device 102, a grinding device, an air separation device, a vibrating screening device and an airflow crushing and classifying device.

[0048] The shearing device includes a shearing cavity 2 , a knife claw mechanism 3 arranged in the cutting cavity 2 , a discharge screen 4 disposed under the knife claw mechanism 3 , and a shearing motor 7 for controlling the knife claw mechanism 3 . . A shearing inlet 5 is provided above the shearing cavity 2 , and a shearing outlet 6 is provided below the shearing cavity 2 at a position on the lower side of the discharging screen 4 . The structure of the knife claw mechanism 3 of the present invention is similar to that of the shearing device in the shearing machine, but the parameters of the knife claw mechanism 3 are improved to be suitable for the embodiment of the present invention, wherein the k...

Embodiment 2

[0056] The method for crushing and sorting solar cell assemblies of the present invention comprises the following steps:

[0057] a. Prepare the equipment for crushing and sorting solar cell modules described in Example 1, and place the solar cell modules with the aluminum frame and glass removed on the conveying platform 1 of the first feeding device 101. At this time, the conveying platform 1 starts to convey, Feed the solar cell module into the shearing device.

[0058] b. The shearing motor 7 drives the knife claw mechanism 3 to cut the solar cell module into component fragments, and the component fragments smaller than the mesh of the discharge screen 4 are screened out through the discharge screen 4 and sent to the second through the discharge port. The feeding device 102, the conveying platform 1 of the second feeding device transports the component fragments to the grinding device through the feeding conveying pipe 9, and the component fragments larger than the mesh of...

Abstract

The invention provides a device and a method for crushing and sorting solar cell modules. The device comprises a shearing device, a grinding device, a winnowing separation device, a vibration screening device and an airflow crushing and grading device. According to the device and the method for crushing and sorting the solar cell modules, a physical environment-friendly method is adopted, the solar cell modules with aluminum frames and the glass removed are cut into fragments through the shearing device, the fragments are ground into a particle mixture through the grinding device, and then plastic particles in the particle mixture are sorted out and collected through the winnowing separation device and the vibration screening device. Battery piece particles are crushed into powder throughthe airflow crushing and grading device, separation and sorting of silicon, silver, aluminum, copper and other elements in battery pieces are achieved, the separation purity of the silicon, silver, aluminum, copper and other elements is high, the treatment speed is high, environment-friendly recycling of waste solar cell modules, especially crystalline silicon modules, can be automatically achieved on a large scale, and the problem of environmental pressure and resource reutilization caused by large-scale retirement of the solar cell modules is solved.

Description

technical field [0001] The invention relates to the field of solar cell recycling, in particular to a device and method for crushing and sorting solar cell components. Background technique [0002] The photovoltaic power generation market is developing rapidly, which requires the photovoltaic modules (solar cell modules) that have exceeded their lifespan, especially the crystalline silicon cell modules and their components (glass, silicon, copper, aluminum, which occupy more than 80% of the world market share) , silver, plastic, etc.) for harmless treatment, and even recycling, can alleviate the shortage of raw materials for photovoltaic devices, and reduce resource waste and ecological environment pollution. [0003] Internationally, the European and Japanese energy industries have carried out in-depth research on photovoltaic module recycling and harmless treatment technologies and management systems, and have incorporated them into regulations and policies. In 2012, the ...
