Problems solved by technology

[0007] The recycling and reuse of solar panels is actually the "reverse" process of panel production, and the above just increases the difficulty of separating glass in this "reverse" process. Ordinary knives cannot remove the EVA film on the panel. The complete peeling off seriously affects the recycling effect of solar panels

Abstract

The invention discloses a steam-jet type hot knife, which includes a knife head, a knife body and a heating coil. The top of the knife body is provided with a groove, and the lower end of the knife head is fixed in the groove by fastening screws; the heating coil is arranged around the knife. The periphery of the body and close to the cutter head; just below the groove, there is a steam channel inside the cutter body. A spout, the steam spout communicates with the steam channel. This application adopts jet steam type hot knife to finely separate the glass in the crystalline silicon solar cell from other components without destroying the structure of the glass plate. The separation rate is high, the integrity rate of the glass is high, and the residual rate of the EVA film is low. The secondary utilization of solar glass panels has made great contributions to the solar cell industry, environment and economic benefits.

Description

technical field [0001] The invention relates to the field of recycling solar battery panels, in particular to a steam jetting hot knife. Background technique [0002] The service life of solar panels can generally reach 25 years. With the growth of time and the influence of the environment, the materials of the panels will gradually age. Attenuation of 70%, almost lost the value of use. [0003] According to the data, the components and content of the battery board are about: 70% glass, 10% aluminum, 10% adhesive sealant, 5% silicon, and 5% other. By 2030, my country's discarded photovoltaic modules can produce 1.1 million tons of glass, 540,000 tons of plastic, 170,000 tons of copper, 260,000 tons of aluminum, 50,000 tons of silicon and 0.055 million tons of silver. It can be seen from these data that the scrapped crystalline silicon solar cells in the future contain a resource value that cannot be underestimated, and it is of practical significance to recycle the discard...
