A kind of e Foerderanlage of electrolysis of aluminum raw material comprises chute, and the two ends of said chute are respectively arranged with opening, is communicated with the thermal source pipeline between the said openings at two ends, and said thermal source pipeline is arranged in the chute, and said thermal source pipeline is communicated with extraneous thermal source.
Preferably, said thermal source pipeline and electrolysis flue gas pipe connection.
Further, the heading of the interior electrolytic aluminum raw material of the flow direction of flue gas and chute is opposite in the said thermal source pipeline.
Preferably, be provided with wire spiral in the said thermal source pipeline.
Preferably, the xsect of said thermal source pipeline is rectangle or circular or Polygons.
Further, the cross-sectional area of said thermal source pipeline is 25-60cm2.
Preferably, the outside surface of said chute is provided with thermal insulating warm-keeping layer.
The e Foerderanlage of the electrolysis of aluminum raw material that the utility model provides has following characteristics:
1, improves the temperature of electrolysis of aluminum raw material, strengthen the stability of electrolyzer.The electrolysis of aluminum raw material gets into electrolyzer through chute, is furnished with the thermal source pipeline in the chute, and the thermal source pipeline is communicated with extraneous thermal source; Make the electrolysis of aluminum raw material before getting into electrolyzer, receive the external heat source heating; Material temperature raises, and behind the entering electrolyzer, caloric receptivity is few; Local temperature difference reduces in the electrolyzer, and the operation of electrolyzer is more stable.
2, electrolysis of aluminum energy consumption reduces.Raw material in the chute is through the mode of external heat source heating, and after raw material got into electrolyzer, the amplitude that electrolyzer temperature reduces was little, and the power consumption of electrolysis of aluminum reduces.External heat source adopts the flue gas that produces in the electrolytic process, and flue-gas temperature is about 150 °, and energy is fully utilized, and has practiced thrift the energy.
