Problems solved by technology

However, this transportation scheme has high energy consumption (about 12kW.h of electricity is consumed per ton of alumina powder for unloading. Taking an electrolytic aluminum plant with an annual output of 300,000 tons of aluminum ingots as an example, only unloading needs to consume 6.912 million kW.h ), the damage rate of alumina powder is serious, and the unloading efficiency is low (it takes about 50 minutes or more to unload a can)

Abstract

The invention discloses a train tanker alumina powder unloading and conveying method and conveying device. The conveying method is characterized in that a set of conveying device is mounted on the outer side of an alumina powder storage bin, and a train tanker loaded with alumina powder is conveyed into the alumina powder storage bin through a conveying system. The conveying device is used for unloading and conveying the alumina powder, has the advantages of simple structure, convenience in implementation, small occupied space and low investment, not only can effectively reduce the breakage rate of the alumina powder and the failure rate of equipment, but also can improve the conveying efficiency and reduce the conveying cost, and is high in practicability and suitable for popularization and application.

Description

technical field [0001] The invention relates to the technical field of material conveying in electrolytic aluminum plants, and is used to convey the alumina powder in the train tank car to the alumina storage bin, in particular to a train tank car alumina powder discharge conveying method Method and delivery device. Background technique [0002] Metal aluminum is one of the important raw materials for my country's industry and national defense construction. Alumina powder is a powder with good fluidity and is not easy to absorb moisture. It is made by smelting alumina powder by molten salt electrolysis in the electrolytic aluminum plant. It needs to consume about 1920kg of alumina powder per ton of aluminum. Taking the electrolytic aluminum plant with an annual output of 300,000 tons of aluminum ingots as an example, it needs about 57.6 kg of alumina powder per year. tons of alumina powder. After the alumina powder is produced by the alumina plant, it is mainly transported...
