Изобретение относитс к получению алюмини электролизом, а именно к способам питани сырьем алюминиевых электролизеров.The invention relates to the production of aluminum by electrolysis, and specifically to methods of feeding raw materials for aluminum electrolysis cells.
Известен способ питани сырьем алюминиевых электролизеров подачей его в дозируемом количестве через вертикальный проем в аноде, причем дл лучшего растворени глинозема в проеме создают вакуум.A known method of feeding raw materials for aluminum electrolysis cells by supplying it in a metered amount through a vertical opening in the anode, and a vacuum is created to better dissolve the alumina in the opening.
Однако в известном способе непосто нен состав электролита и концентрации глинозема, а также высокий расход сырь , электроэнергии и трудозатрат.However, in the known method, the composition of the electrolyte and the concentration of alumina, as well as the high consumption of raw materials, electricity and labor costs are not constant.
Предлагаемый способ отличаетс тем, что сырье подают одновременно с инертным газом под давлением на 5-20Vo П1ревышающем давление анодных газов.The proposed method is characterized in that the feedstock is fed simultaneously with an inert gas at a pressure of 5-20Vo exceeding the pressure of the anode gases.
Это позвол ет поддерживать посто нный состав электролита и концентрации глинозема и сократить расход сырь , электроэнергии и трудозатрат.This allows you to maintain a constant electrolyte composition and alumina concentration and reduce the consumption of raw materials, electricity and labor.
Количество загружаемого сырь дозир етс питателем, а врем загрузки определ етс датчиком, работающем в зависимости от давлени анодных газов. Сырье подают в аэрированном виде, причем дл лредопвращенн его зависани в полости вертикального проема последн находитс под давлением инертного газа, например, азота, на 5-20% превышают давление анодных газов. Это позвол ет создать газовый мениск, что улучшает переход шихты из вертикального проема в электролит. Иодача инертного газа улучшает также и растворение глинозема.The amount of feedstock is dosed by the feeder, and the loading time is determined by a sensor operating depending on the pressure of the anode gases. The raw material is supplied in aerated form, and to prevent it from hanging in the cavity of the vertical aperture, the latter is under the pressure of an inert gas, for example nitrogen, 5-20% higher than the pressure of the anode gases. This allows a gas meniscus to be created, which improves the transfer of the charge from the vertical opening to the electrolyte. Iodacha inert gas also improves the dissolution of alumina.
