Patent ID: 11261095

Abstract:
A manufacturing system and method for recycling and smelting crushed silica from silicon plants, including a crushed silica storage device, granulator, submerged arc furnace, transfer device, forming device and cooling system. Firstly silicon waste is collected, then crushed silica is output to a granulator. The granulator mixes the waste irregular crushed silica with water, and granulates and produces small particles having an uniform grain size as the raw material for smelting. The raw material is smelted in the submerged arc furnace. The forming device evenly pours the silicon liquid into the cooling system according to a set flow rate. The silicon liquid is solidified to form silicon pellets, and then a lift system is used to lift the formed silicon pellets, wherein the silicon liquid poured into the cooling system has a uniform diameter. The system can rapidly and efficiently smelt the silicon waste from the silicon plants.
