Embodiment 1

[0046] Such as figure 1 As shown, the equipment of the present invention includes a first feeding device 101, a hammer crushing and splitting device, a second feeding device 102, a wind separation device, a vibration screening device, an electrostatic separation device and an air flow crushing and grading device.

[0047] The hammering and splitting device includes a hammering chamber 2, a hammering mechanism 3 arranged in the hammering chamber 2, a discharge screen 4 arranged below the hammering mechanism 3, and a hammering mechanism for driving the hammering mechanism 3. motor7. There is a hammering inlet 6 on the upper side of the cavity, and a hammering outlet 5 on the lower side of the discharge screen 4 of the cavity. The hammering mechanism 3 includes a rotating shaft and 5-20 hammers arranged on the rotating shaft. One end of the hammers is evenly arranged coaxially along the rotating shaft. The hammering motor 7 controls the rotating shaft to drive the hammers to rot...

Embodiment 2

[0054] The method for crushing and sorting solar cell components of the present invention comprises the following steps:

[0055] a. Prepare the equipment for crushing and sorting solar cell assemblies described in Example 1, and send the solar cell assemblies without the aluminum frame and glass to the hammering and dismantling device.

[0056] b. The hammering motor 7 of the hammering and splitting device drives the hammer blade of the hammering mechanism 3 to rotate, and the hammer blade crushes the solar battery module, the plastic of the module is hammered into plastic particles, and the battery sheet of the module is hammered into silicon particles and Metal welding strip particles, metal converging belt particles, these particles form a particle mixture; the particle mixture smaller than the 4 meshes of the discharge screen is sieved out through the screen mesh, and sent to the second feeding device 102 through the hammering discharge port, Sent to the winnowing separat...

Abstract

The invention provides an equipment and method for crushing and sorting solar cell components. The equipment for crushing and sorting the solar cell components comprises a hammering and splitting device, a winnowing separation device, a vibratory screening device, an electrostatic sorting device and an airflow crushing and grading device. A physical environmental protection method is adopted. Thesolar cell components, which remove aluminum frames and glass, are hammered into particle mixtures by the hammering and splitting device, and plastic particles are screened for recycling and meanwhilecopper materials such as metal solder strip particles and metal bus bar particles are screened and recycled in advance. The remaining particle mixtures are crushed into powder through the airflow crushing and grading device, so that the separation and sorting of silicon, silver, aluminum and other elements in cells is realized. The equipment has high processing speed, can automatically realize environmentally-friendly recycling of waste solar cell components, especially crystal silicon components on a larger scale, and solves the problems of environmental pressure and resource reuse caused bylarge-scale decommissioning of the solar cell components are solved.

Description

technical field [0001] The invention relates to the field of solar battery recycling, in particular to a device and method for crushing and sorting solar battery components. Background technique [0002] The photovoltaic power generation market is developing rapidly, which requires the photovoltaic modules (solar cell modules) after their lifespan, especially the crystalline silicon cell modules and their components (glass, silicon, copper, aluminum, etc.), 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 technology and management systems, and have incorporated them into regulations and policies. In 2012, the Eur...
