Silicon removal device for crude nickel sulfate liquid

The utility model relates to the technical field of nickel sulfate production, in particular to a silicon removal device for crude nickel sulfate liquid, and aims to solve the problem that in the current nickel sulfate production process, when silicon removal is carried out on the crude nickel sulfate liquid, the silicon removal efficiency is low. Due to the adoption of traditional multi-stage silicon removal equipment, the steps in the silicon removal process are complicated, the labor intensity of operators is high, the utilization rate of an equipment site is low, and the silicon removal progress and the overall production efficiency of nickel sulfate are finally influenced. The device mainly comprises a kettle body, a liquid inlet, a liquid outlet, a stirring device, a feeding port, a heat tracing pipe and the like, crude nickel sulfate liquid is added into the kettle body, alkali liquor and a flocculating agent are added into the crude nickel sulfate liquid, and the heat preservation effect of steam in t
