Abstract

The invention relates to an automatic ash removal device for a flue, in particular to an automatic ash removal device for a flue of an aluminum electrolysis cell. By the adoption of the ash removal device, ash removal for the gas collection flue can be achieved by means of tail gas of a crust-breaking and feeding system used for the aluminum electrolysis cell. The automatic ash removal device for the flue of the aluminum electrolysis cell comprises a crust-breaking cylinder and a constant-volume feeder. An exhaust vent of the crust-breaking cylinder and an exhaust vent of the constant-volume feeder are connected with an ash removal pipe arranged in the flue through hoses correspondingly. By the adoption of the automatic ash removal device for the flue of the aluminum electrolysis cell, automatic ash removal for the gas collection flue can be achieved by effectively utilizing the tail gas of the crust-breaking and feeding system, the energy utilization rate is increased, the gas collection effect of the flue and the sealing efficiency of the aluminum electrolysis cell are effectively guaranteed, the work of manual removal of accumulated ash in the flue is completely eliminated, and flying loss of aluminum oxide raw materials in the manual ash removal process is avoided.

Description

technical field [0001] The present invention patents an automatic ash removal device for flue, in particular to an automatic ash removal device for aluminum electrolytic cell flue that realizes gas collection flue exhaust gas from shelling and feeding system for aluminum electrolytic cell. Background technique [0002] During the production and operation of aluminum electrolytic cells, two problems are generally encountered. One is that the dust accumulation in the gas collecting flue is difficult to clean up, and the other is how to deal with the exhaust gas of the compressed air used in the shelling and feeding system. [0003] Regardless of whether the electrolytic cell adopts the upper flue gas collection structure or the lower flue gas collection structure, the dust accumulation in the flue is always an inevitable problem, and seriously affects the gas collection effect of the flue. Some aluminum factories use compressed air from the electrolysis workshop to regularly b...
