以前,使用电解车间的天车和料斗,向电解槽输送原料(氧化铝和添加物)时,原料外溢,引起电解厂房内和大气环境污染,增加额外的管理费用,降低槽寿命,电压降升高。然而,氧化铝可从中央贮仓和中间贮仓自动地通过无尘输送装置,按需要量输送到电解槽的料斗或直接加到壳面上。研究了各种各样的物料输送和自动控制方法。新的物料输送方法可以 In the past, when using pots and hoppers from the electrolysis plant to feed raw materials (alumina and additives) to the electrolyzer, the raw materials spilled, causing pollution in the electrolysis plant and the atmosphere, adding additional overhead, reducing tank life, voltage drop high. However, alumina can be fed from the central silo and the intermediate silo automatically to the hopper of the cell or directly to the shell surface via a dust-free conveyor, on demand. Studied a variety of material handling and automatic control methods. The new material delivery method can be
