Quantitative feeding device for aluminum electrolytic cell

Abstract

The invention discloses a quantitative feeding device for an aluminum electrolytic cell. The quantitative feeding device comprises a discharging device arranged over an electrolytic cell hopper in the aluminum electrolytic cell, a feeding and conveying device arranged above the discharging device and a power source connected with the discharging device and the feeding and conveying device at the same time. The discharging device comprises a discharging hopper, a rotary weighing cone arranged at the bottom of the discharging hopper, a discharging motor arranged on the outer side of the discharging hopper and connected with the rotary weighing cone and the power source. The discharging hopper is further provided with an anti-accumulation cone. A pressure-sensitive delay control circuit is further arranged between the power source and the discharging motor. By means of the quantitative feeding device for the aluminum electrolytic cell, precise feeding can be well guaranteed each time, consumption of materials and output of pollutants are lowered greatly, production devices can be well protected, and the service life of the production devices is prolonged.

Description

technical field [0001] The invention belongs to the field of feeding materials for aluminum electrolytic cells, and specifically refers to a quantitative feeding device for aluminum electrolytic cells used in aluminum production. Background technique [0002] At present, the development level of the domestic aluminum electrolysis production field is far behind the international average level. The biggest problems are serious production pollution, short service life of production equipment, and serious consumption of energy consumption and production materials in the production process. Greatly limit the development of my country's aluminum electrolysis industry. One of the key reasons for the above problems is that my country's aluminum electrolysis feeding device is relatively simple, and its feeding accuracy is low, and when the proportion of ingredients is not suitable, it is easy to generate a large amount of smoke pollution, which aggravates the enterprise's handling of ...

[0002] At present, the development level of the domestic aluminum electrolysis production field is far behind the international average level. The biggest problems are serious production pollution, short service life of production equipment, and serious consumption of energy consumption and production materials in the production process. Greatly limit the development of my country's aluminum electrolysis industry

One of the key reasons for the above problems is that my country's aluminum electrolysis feeding device is relatively simple, and its feeding accuracy is low, and when the proportion of ingredients is not suitable, it is easy to generate a large amount of smoke pollution, which aggravates the enterprise's handling of smoke. The cost of gas, and a large amount of precipitation will be generated when too much material is added, which not only increases the consumption of production resources, but also increases the output of solid pollutants, and also erodes the production equipment, greatly reducing the cost of production equipment. service life
