Description
TECHNICAL FIELD
[0001] The utility model relates to the field of renewable resources recycling, in particular to a sorting equipment for glass, battery piece and solder strip in photovoltaic recycling materials. BACKGROUND
[0002] The photovoltaic assembly is the related equipment for helping solar energy conversion into electric energy, because solar energy is renewable energy, and any environmental pollution will not be generated in the conversion process, the photovoltaic industry has obtained the rapid development in recent years, is set up and installed in all parts of the world, however, the service life of photovoltaic assembly is about 25 to 30 years, and most of the constituent materials of photovoltaic assembly are recyclable materials, so after the service life of photovoltaic assembly expires, it is usually recycled and treated to recycle the recyclable materials contained in it.
[0003] When recycling the scrapped photovoltaic assembly, the assembly usually needs to be disassembled first, and then the aluminum frame, glass and junction box are removed, and then the remaining photovoltaic board is crushed, and the EVA adhesive layer in the photovoltaic board is decomposed by high-temperature incineration method and chemical treatment method, so as to obtain valuable recyclables such as silicon wafer, glass and solder strip contained in it, because the silicon wafer, glass and solder strip are mixed together, and the sales of each recyclable product is separate, therefore, these products need to be sorted.
[0004] CN217664711U discloses a sorting device for glass particles and silicon wafer particles, which is based on the fact that the thickness of glass particles and silicon wafer particles is not consistent, and the thickness of glass particles is several times that of silicon wafer particles. Therefore, by taking advantage of the difference in thickness, when the glass particles and silicon wafer particles are displaced to the input port part of the second discharge hopper, the silicon wafer particles pass through the gap between the second discharge hopper and the belt conveying mechanism and enter the first discharge hopper, but the glass particles are blocked by the second discharge hopper and cannot pass through the gap between the second discharge hopper and the belt conveying mechanism and enter the first discharge hopper.
[0005] Although the above sorting device can separate glass particles and silicon wafer particles, some small-volume glass particles are easily blocked at the input port part of the second discharge hopper, which needs to be cleaned from time to time, resulting in reduced sorting efficiency. UTILITY MODEL CONTENTS
[0006] The utility model provides a sorting equipment for glass, battery piece and solder strip in photovoltaic recycling materials, which can avoid blockage and improve sorting efficiency.
[0007] The technical solution to solve the above technical problems is as follows:
[0008] The application discloses a sorting device for glass, battery pieces and solder strips in photovoltaic recycling materials, which comprises a rack, a material guiding component, a first roller assembly, a second roller assembly, a first driving assembly, a second driving assembly and a plurality of material receiving containers.
[0009] When the device is used, the mixture of glass, battery pieces and solder strips is input into the material guiding component and then slides along the material guiding component and enters between the first roller assembly and the second roller assembly. The first roller assembly drives the first driving assembly to rotate in a first direction, and the second roller assembly drives the second driving assembly to rotate in a second direction. The first direction and the second direction are opposite, and the mixture of glass, battery pieces and solder strips is displaced by the force generated by the first roller assembly and the second roller assembly. Since there is a gap between the first roller assembly and the second roller assembly, the material with a thickness smaller than the gap falls into the material receiving containers below the roller assemblies after passing through the gap. Since the gap is narrow at one end of the two roller assemblies and wide at the other end, materials with different thicknesses can be separated. The first half of the gap can sequentially separate battery pieces and solder strips, and the second half of the gap can separate glass with different specifications. The device is usually used in the first sorting process of the mixture. BRIEF DESCRIPTION OF DRAWINGS
