Description
Изобретение относитс к области цветной металлургии , в частности, к производству алюмини электролизом расплавов, н может быть использовано на электролизерах дл получени алюмини с верхним {подводом тока. Известно устройство дл улавливани газов алюминиевого электролизера с верхним подводом тсиса, включающее раму с направл кшщми, анодный кож;пс, кольцевой газосборник и щитовое укрытие 1 Известное устройство характеризуетс повышенным выделением газа н теплового излучени в рабочую зону электролизера из-за шолотиого прилегани газосборника к корке электролита, особеино при ее разрушеник. Целью изобретен вл етс умеиьивние попадаии в рабочую эсшу электролизера газов и теплового излучени . Цель достигаетс тем, что ощтовое укрытие выполнено в виде верхнего и нижнего экранов и установлено с зазором вдоль стенок анодного кожуха; экраны могут быть соединены между собой шарнирно, с возможностью вращешш вокруг оси, параллельной стенкам анодного кожуха, & также могут быть установлены в направл ющих аноднойГ рамы с возможностью взаимного перемещени . На фиг. 1 схематично изображено пре.дложенное устройство, в котором экраны соединены шарнирно с возможностью вращени вокруг оси, параллельной стенкам анодного кожуха; на фиг. 2 - то же, экраны установлены в направл ющихрамы с возможностью перемещени . На фиг. 1 и 2 схематически изображен электролизер 1 с футеровкой 2, анодом 3 и кольцевым газосборником 4,ош1рающимс на корку электролита 5. Устройство включает также щитовое укрытие, выполненное в виде нижнего экрана 6 и верхнего экрана 7. Экраны 6 и 7 соединены шарнирно на оси 8, параллельной стенкам анодного кожуха 9. Нижний экран 6 опираетс на основание корпуса с 1азором 10 между электролизером и основанием. На фиг. 2 нижн 11 и верхн 12 части щитов ч-о укрыти установлены в направл ющих рамы 13. При работе электролизера через зазор 10 под воздействием естественной т ги просасываетс воздух , что предотвращает выброс газов в рабочую зону электролизера. Прт обработке электролизера, выливке металла поднимаетс нижний экран 6 или нижн часть 11The invention relates to the field of non-ferrous metallurgy, in particular, to the production of aluminum by the electrolysis of melts, which can be used on electrolyzers for the production of aluminum with an upper current supply. A device for capturing gases of an aluminum electrolytic cell with a top cysis supply, including a frame with guides, anode leather, ps, annular gas collector and panel cover 1, is known. The known device is characterized by increased gas emission and thermal radiation in the working area of the electrolyzer due to a chilly fit of the gas collector to the box. electrolyte, especially at its destruction. The goal of the invention is to reduce the amount of gas and thermal radiation into the working cell. The goal is achieved by the fact that the perceptive cover is made in the form of upper and lower shields and installed with a gap along the walls of the anode casing; the screens can be interconnected pivotally, with the possibility of rotation around an axis parallel to the walls of the anode casing, & can also be installed in the guides of the anode frame with the possibility of mutual movement. FIG. Figure 1 shows schematically an attached device in which the screens are pivotally connected with the possibility of rotation around an axis parallel to the walls of the anode casing; in fig. 2 - the same, the screens are installed in the guides of the frame with the possibility of movement. FIG. 1 and 2 schematically depict an electrolyzer 1 with lining 2, an anode 3 and an annular gas collector 4, which attaches to the electrolyte crust 5. The device also includes a shield cover made in the form of the lower screen 6 and the upper screen 7. Screens 6 and 7 are connected pivotally on axis 8 parallel to the walls of the anode casing 9. The lower screen 6 rests on the base of the housing with 1 gap 10 between the electrolyzer and the base. FIG. 2 lower 11 and upper 12 parts of the shields of the shelter cover are installed in the guide frames 13. During operation of the electrolyzer, air is sucked through the gap 10 under the influence of natural draft gas, which prevents the emission of gases into the working area of the electrolyzer. When processing the electrolyzer, the metal is poured and the bottom screen 6 or bottom part 11 is raised.
укрыти . Соответственно верхний экран 7 или верхн часть J 2 опускаетс при операци х, св занных с обслуживанием анодного устройства.shelter Accordingly, the upper screen 7 or the upper part J 2 is lowered during operations associated with servicing the anode device.
Таким образом, предложенное устройство защищает рабочую зону электролизера от попадани в нее газов и теплового излучени .Thus, the proposed device protects the working area of the electrolyzer from the ingress of gases and thermal radiation into it.
