Silicon sludge drying device capable of recycling heat

Abstract

The silicon sludge drying device comprises an upper box body and a lower box body, the upper box body and the lower box body are connected in a clamped mode, fan blades are fixedly connected to the outer surface of a fixing shaft, and the fan blades are attached to the inner wall of a turbine box. And control boxes are fixedly connected to the middle parts of the front surface and the bottom of the back of the upper box body through fixing pieces. According to the silicon sludge drying device capable of recycling the heat, heat energy steam generated when silicon sludge is dried can be effectively recycled, the turbine is pushed to rotate in a steam engine mode along with rising of hot air, the turbine indirectly drives the claw below after rotating, the heat energy generated when the silicon sludge is dried is effectively utilized, and the silicon sludge drying device is energy-saving and environment-friendly. And all the silicon sludge is returned and applied to drying operation, so that the whole work saves more energy, the situation that the silicon sludge is dried unevenly does not need to be worried about, and on the premise that the energy is saved, people can use the silicon sludge drying device conveniently.

Description

technical field [0001] The invention relates to the technical field of silicon mud processing, in particular to a silicon mud drying device with recyclable heat. Background technique [0002] Using silicon slime as raw material, it is smelted into silicon metal in electric furnace. Because of its high moisture content and fine particle size, the yield of silicon slime is less than 20% after being put into electric furnace. Most of the raw materials are easily oxidized or form silicon oxide and other other materials In the silicon wafer cutting process in the solar field, solar-grade battery silicon wafers are cut from silicon blocks or silicon rods by a multi-wire cutting machine. According to the current industry development trend, diamond wire is more Wire cutting technology will become the mainstream of multi-wire cutting in the future. In the diamond wire cutting process of single crystal silicon or polycrystalline silicon, the silicon powder generated when the diamond w...
