Cleaning method and device for anode roasting fire path wall

Abstract

The invention discloses a method of cleaning a flue wall of an anode baking furnace and a device. The method includes the steps of feeding a rotating plate with a wire brush fixed thereon in the flue wall of the anode baking furnace; pushing the rotating plate towards the flue wall by a push device which is connected with the rotating plate, so that the wire bush on the rotating plate comes into close contact with the flue wall; and cleaning the flue wall through rotary friction between the wire bush on the rotating plate and the flue wall. By adopting the method of the invention, the operation requires no entry into the baking furnace when a worker clean the flue wall; the operation can be done when the worker just stands on the furnace surface of a multifunctional crown block, thus greatly reducing the heavy physical labor when the worker clean the flue wall, improving the working environment and the labor intensity of the worker, and at the same time shortening shut-down time of the baking furnace and improving the production efficiency; the cleaning quality is remarkably improved, thus prolonging service life of the baking furnace and reducing maintenance expense of the baking furnace.

Description

technical field [0001] The invention relates to a method and a device for cleaning the flue wall of an anode roasting furnace, and belongs to the technical field of cleaning an anode roasting furnace. Background technique [0002] Anode roasting is an important process in the production of electrolytic aluminum anodes. Its method is to use a crane device to feed the raw anode carbon block into the roasting furnace for roasting at high temperature to harden it into a clinker anode. This process can improve the electrolysis efficiency and durability of the electrolytic aluminum anode, and greatly reduce the production cost of electrolytic aluminum. However, since the carbon block itself is extruded from materials such as carbon powder, pitch and coal tar, during the high-temperature roasting process, materials such as pitch and coal tar will volatilize and bond with the surrounding dust in a high-temperature environment. Fire path wall. After a long period of accumulation, t...

Problems solved by technology

[0003] At present, the cleaning work of the flue wall mainly relies on manual cleaning. The cleaning method is: first stop the roasting furnace, and after the temperature in the roasting furnace is lowered, the workers directly enter the roasting furnace to clean the solidified matter on the flue wall. Cleaning, because the temperature in the roasting furnace drops very slowly, it takes a long time to shut down the furnace. On the other hand, the consolidated matter is very firmly bonded, and the cleaned-up consolidated matter will raise a lot of dust

During the cleaning process, the workers have an extremely poor working environment and high labor intensity. The cleaning efficiency is extremely low. It takes a long time to clean up, and the cleaning effect is not ideal.
